1.1 Introduction
Meteorology, at its heart, is the scientific endeavor dedicated to understanding the Earth’s atmosphere and the myriad phenomena that occur within it. More than just the art of predicting whether it will rain tomorrow, meteorology is a robust interdisciplinary science. It intricately weaves together principles from physics, chemistry, and mathematics to unravel the complexities of atmospheric processes. From the gentle caress of a breeze to the formidable power of a hurricane, meteorology seeks to explain the underlying mechanisms that drive our ever-changing weather and long-term climate patterns.
The study of meteorology encompasses a wide array of atmospheric characteristics. Meteorologists delve into the composition of the atmosphere, examining the various gases and tiny particles known as aerosols that reside within it. They also investigate its vertical structure, distinguishing between layers like the troposphere, where most weather occurs, and the stratosphere, home to the ozone layer. The motion of the atmosphere, manifested as wind systems ranging from local gusts to global circulations, is a central focus. Furthermore, meteorology explores the thermodynamics of the atmosphere, including how heat is transferred and how temperature changes, as well as the role of water in the atmosphere, from humidity to the formation of clouds and precipitation – the realm of atmospheric hydrology. Even the captivating
optical phenomena we sometimes witness, such as rainbows and halos, fall under the purview of meteorological inquiry.

OPERATING MECHANISM OF A FLOUR MACHINE
The flour grinding machine operates using blade cutting, high-speed air impact, and a two-layer destruction function that integrates collision and particle sorting. The principle of operation involves the rotor generating high-speed airflow during blade cutting. As the material accelerates within the airflow, repeated impacts cause it to be destroyed in two layers simultaneously, enhancing the destruction rate.
As airflow enters the classification chamber, the destruction process rotates at high speed, and the classification rotor generates centrifugal force. The viscous effect of the airflow creates centripetal force. When the centrifugal force on the particles exceeds the centripetal force, the coarse particles return to the destruction chamber, while fine particles are carried with the airflow to the powder collector for collection.
There are three primary operating characteristics of the flour mill. First, the main shaft in the power system is sequentially equipped with bearing caps, radial ball bearings, bearing pads, and thrust ball bearings from top to bottom. Second, the grinding system consists of a spring, spring pad, inner grinding head, adjusting nut, and outer grinding head mounted on the spindle. Lastly, the separation system features a brush mounted on the spindle, with a tension spring above and an adjusting nut below the brush.
The core principle of the flour grinding process is to reduce grains like wheat, corn, or rice into flour particles. Raw grains are introduced into the mill's hopper and then conveyed to the grinding chamber containing the grinding stones or rollers. As the grains pass through the chamber, the high-speed rotation of the stones or rollers generates friction that crushes, grinds, and pulverizes the grains into a coarse powder, which gradually becomes fine flour.

Introduction
An ecosystem is any unit that consists of all the creatures, or communities, in a certain area that interact with the physical environment to produce a trophic structure, biodiversity, and material cycle within the system. Various biosphere ecosystem types are
1) Natural ecosystems
2) Man-made ecosystems
Natural Ecosystems
Under natural conditions, these ecosystems function independently with little to no significant human intervention. These are further separated as follows based on the specific type of habitat:
• Terrestrial: grasslands, deserts, and forests
• Aquatic (open to the water), which is further subdivided into

Packaging machinery is integral to all packaging processes, from primary packaging to distribution packs. It encompasses various stages, including fabrication, cleaning, filling, sealing, combining, labeling, overwrapping, and palletizing.Food packaging refers to the methods, materials, and technologies used to package food items. It serves multiple purposes, such as prolonging the shelf life of products. However, food packaging is not a recent innovation, and its history is quite fascinating.
Food packaging has existed in various forms throughout history. The Journal of Agricultural and Food Chemistry highlights that Napoleon played a major role in its development by offering a reward of 12,000 francs for anyone who could invent a method to preserve food for his army. This prize went unclaimed for 15 years until Nicholas Appert introduced the canning method. Appert’s process involved boiling food and sealing it in airtight glass containers, laying the foundation for modern canned food as we know it today.
EVOLUTION OF FOOD PACKAGING THROUGH AGES
The history of food packaging dates back centuries! The Chinese were pioneers in developing paper and wrapping materials, which were utilized for storing food. In ancient Egypt, advancements were made in glass-blowing and molding techniques, allowing glass to be shaped into various forms for food and water storage.

Introduction
In the past, the approach to disaster management was relief-focused and restricted to helping the area affected by the disaster. involves a continuous and integrated process of organizing, coordinating, and putting into action measures that are required or advantageous for preventing danger or threats, mitigating risk or its severity or consequences, building capacity through research and knowledge management, being ready to deal with any disaster, responding quickly to any situation that poses a threat to the community, determining the extent or severity of effects, evacuation, rescue and relief efforts, rehabilitation, and reconstruction.
Phases and Elements in Disaster Management
I. Pre-disaster phase: There are three components to the pre-disaster phase: preparedness, mitigation, and prevention.
II. The aftermath phase, encompassing response, recuperation, and restoration. All these components are connected by a structure of institutions and legislation.

Natural Farming (NF) represents a sustainable approach to agriculture that draws upon ecological principles, minimizes reliance on external inputs, and makes extensive use of locally available resources. In contrast to conventional farming—which often depends on synthetic fertilizers and commercial animal feed—natural farming seeks to foster balance among the soil, crops, animals, and microbial life. Popularized in India by Subhash Palekar, this method promotes the use of natural preparations such as Jeevamrit, Beejamrit, and practices like mulching to enrich soil fertility and support plant vitality.
A core aspect of natural farming is the inclusion of livestock, which significantly contributes to nutrient recycling, weed suppression, and overall farm efficiency. Products like cow dung and urine form the basis of microbial formulations that boost soil activity and crop productivity. Livestock also contribute to ecological health through regulated grazing, pest management, and the breakdown of organic residues.
Animals such as cows, buffaloes, goats, sheep, backyard poultry, and fish are effectively integrated into the NF system to form a cohesive and regenerative agro-ecosystem. These animals enhance crop systems by providing organic inputs while simultaneously benefiting from pesticide-free fodder and farm-generated feed, leading to healthier livestock and improved quality of dairy, eggs, and meat.
This interdependent model reduces the need for external feed inputs, enhances natural animal wellness, and raises farm income, particularly for smallholders. Natural farming promotes the use of native breeds that thrive in local conditions with minimal intervention.
Ultimately, integrating livestock within natural farming is not just beneficial— it is vital for establishing robust, regenerative farm systems. This synergy between animals and crops supports ecological sustainability, strengthens food systems, and uplifts rural communities.

The presence of water in its various phases (gas, liquid, and solid) within the atmosphere plays a pivotal role in shaping our weather and climate.This chapter, „Water Vapor in the Atmosphere,“ will delve into the crucial concept of atmospheric humidity – the amount of water vapor in the air. Water, unique in its ability to exist in all three states at Earth‘s temperatures, undergoes phase changes that are fundamental to the formation of clouds, precipitation, and atmospheric stability. Understanding the sources of atmospheric moisture, the ways it is measured and expressed, and its influence on atmospheric processes is essential for comprehending a wide range of meteorological phenomena. We will explore concepts such as evaporation, condensation, humidity indices, and the role of moisture in energy transfer within the Earth-atmosphere system. Join us as we unravel the dynamics of this vital component of our atmospheric environment.
8.1. Expressions Used for Water Vapor in the Atmosphere
The concepts of vapor pressure, saturated vapor pressure, vapor pressure deficit, and dew point has been discussed with detailed explanations:
8.1.1. Vapor Pressure (e)
Vapor pressure is the partial pressure exerted by water vapor molecules in ,the air. It represents the contribution of water vapor to the total atmospheric pressure. Imagine air as a mixture of gases; the vapor pressure is the „pressure“ exerted solely by the water vapor component of that mixture.

From the farmer deciding when to sow seeds to the traveler planning their journey, from the pilot navigating the skies to the energy provider managing demand, the state of the atmosphere profoundly influences our daily lives and myriad human activities. The ability to anticipate future atmospheric conditions, a practice we know as weather forecasting, is therefore not merely an academic pursuit but a practical necessity (Fig. 16.1).
This chapter will delve into the fascinating world of weather forecasting, exploring its historical roots, the fundamental scientific principles that underpin it, and the sophisticated tools and techniques employed by modern meteorologists. We will journey through the process of observing the current state of the atmosphere, the computational power used to model its complex dynamics, and the various ways forecasts are disseminated and interpreted.
Understanding the science behind weather forecasting empowers us to appreciate its capabilities and limitations. It allows us to make more informed decisions in the face of an ever-changing atmospheric environment. Join us as we unravel the methods used to predict the weather, from simple observations to cutting-edge numerical models, and gain insight into the continuous advancements shaping the future of this vital scientific discipline.

Agriculture, the cultivation of plants and rearing of animals for food, fiber, and other products, is intrinsically linked to the Earth’s climate. Temperature, rainfall patterns, and atmospheric composition profoundly influence agricultural productivity and distribution. However, the stability of these climatic conditions is increasingly threatened by climate change, driven primarily by the escalating concentration of greenhouse gases in the atmosphere. This chapter delves into the multifaceted relationship between climate change and agriculture, exploring the ways in which altered climatic conditions affect agricultural practices, productivity, and sustainability. We will examine the impact of rising temperatures, shifting precipitation patterns, and increased frequency of extreme weather events on crop yields, livestock health, and overall agricultural output. Furthermore, the chapter will discuss the implications of these changes for global food security, economic stability, and the livelihoods of millions of people who depend on agriculture. Finally, we will explore strategies for mitigating the adverse effects of climate change on agriculture and enhancing the resilience of agricultural systems in the face of this unprecedented challenge.

Agriculture, the cultivation of life that sustains human civilization, is profoundly intertwined with the rhythms of the natural world. Of all the environmental factors that influence farming, weather reigns supreme, orchestrating a complex symphony of elements that dictate the success or failure of crops. This chapter delves into the intricate relationship between weather and agriculture, exploring how temperature, precipitation, sunlight, and other atmospheric conditions shape every facet of agricultural production.
Weather’s influence begins with the very first stage of a plant’s life. Temperature governs seed germination and seedling development, while sunlight provides the energy for photosynthesis, the process by which plants convert light energy into chemical energy. The availability of water, dictated by rainfall patterns, is crucial for plant growth and nutrient absorption. Wind patterns can aid in pollination but also cause damage to crops.
Throughout the growing season, weather continues to play a critical role. Optimal temperatures are essential for each stage of plant development, from flowering to fruit production. Adequate rainfall, or irrigation to supplement it, ensures healthy growth and abundant yields.
Extreme weather events, such as droughts, floods, heatwaves, and frosts, can have devastating consequences for agriculture. These events can destroy crops, reduce yields, and disrupt food production, leading to economic losses and food insecurity (Fig. 18.1).

In an era defined by increasing climate variability and the urgent need for sustainable food production, the science of Agricultural Meteorology has risen to unprecedented importance. This chapter, “Agricultural Meteorology: An Essential Associate for Natural Farming,” synthesizes the principles and applications we have explored, highlighting their critical role by providing timely, location-specific insights into weather and climate - factors that directly influence crop growth, soil health, and ecological balance. Unlike conventional farming, which often relies on synthetic inputs to manage uncertainty, natural farming depends heavily on understanding and adapting to natural rhythms. Here, agrometeorology becomes an indispensable ally.
Natural farming systems are sensitive to changes in temperature, rainfall, humidity, wind, and solar radiation. Agrometeorology helps farmers monitor and interpret these parameters, enabling them to make informed decisions such as when to sow, irrigate, mulch, or harvest — all without chemical interventions. For instance, knowing the onset of monsoon or forecasted dry spells helps in planning sowing operations or preparing natural plant protection measures like cow dung-based formulations.

The study of animal nutrition is a complex and important field that requires a detailed understanding of the various nutrients that are essential for the proper functioning of an animal’s body. These nutrients, including proteins, carbohydrates, vitamins, minerals, and fats, play a crucial role in metabolism and serve different functions such as providing energy, promoting growth and development, maintaining bodily functions, and supporting immunity. It is imperative to have a thorough knowledge of their quantitative requirements and the sources from which they can be obtained for scientific feeding practices. This knowledge has been gained through extensive research and experience over the years. Therefore, it is crucial for students studying nutrition to understand the methods used to acquire this knowledge and how it continues to evolve through ongoing research. This in-depth understanding will enable them to make informed decisions when it comes to providing optimal nutrition for animals.
Advantages of Scientific Feeding
Scientific feeding offers numerous advantages compared to standard feeding practices.
1. It guarantees that animals receive the correct amount and balance of nutrients, leading to improved health and a decreased risk of metabolic disorders.
2. It enhances feed utilization efficiency, resulting in lower production costs and reduced environmental impact in animal agriculture.
3. It improves the quality and safety of animal products, boosting their market value and consumer acceptance.
Challenges of Scientific Feeding
Despite its benefits, scientific feeding also encounters some challenges.
1. It requires skills and knowledge that small farmers may not have or can’t afford.

Nutrition plays a significant role in any livestock development program, and the expression of genetic potential for production depends on the adequate supply of nutrients. For profitable livestock production, it is essential to feed livestock nutritionally balanced diets with minimum cost and wastage, as feed cost accounts for more than half of the cost of livestock produce. Providing a balanced diet to animals can reduce feed costs, minimize nutrient wastage, and improve feed efficiency, thereby positively impacting the environment by reducing nutrient excretion.
The demand for animal products such as milk, meat, and eggs is constantly increasing to meet the needs of the growing human population. Better awareness of health and rapid urbanization, with a higher preference for quality animal products, has further fueled this demand. Human food is incomplete in terms of optimum nutrition without animal products like meat, milk, and eggs. To maximize the production of animal products according to their genetic potential, animals must be fed a balanced ration scientifically formulated to provide all essential nutrients.
Balanced feeding involves feeding livestock according to their requirements to achieve growth and production in line with their genetic potential. Understanding the nutrient requirements and the relative value of feeds as a source of these nutrients is the foundation of scientific feeding. Effective measures to achieve a balanced diet include accurate feed formulation based on the nutritional value of each feed ingredient, precise quantification, proper blending of different feedstuffs, optimal use of mineral mixtures, salt, feed additives, and the application of improved feed processing techniques tailored to the relevant species of livestock.

Imbalance between feed availability, feed ingredient prices, and livestock product prices, such as milk, meat, and eggs, leads to poor animal performance, low growth rates, reduced reproductive efficiency, and high morbidity and mortality rates. This issue is particularly severe in South Asian countries like Pakistan, Nepal, India, and Bangladesh, where there is a widespread lack of sufficient high-quality feed. To address this challenge, it is essential to develop technologies for utilizing non-conventional feeds and fibrous agricultural residues more effectively.
The large number of livestock in these countries is both an asset and a liability. Many of the less productive animals are owned by impoverished individuals who have no alternative livelihood options and cannot reduce their livestock numbers. Therefore, efforts must be made to enhance production by optimizing the use of available feed resources, minimizing losses from diseases and parasites, implementing better management practices, and focusing on genetic improvement. The primary feed resources in these regions are crop residues, such as rice and wheat straws, sorghum and maize stovers, and sugar cane bagasse. These materials are typically low in protein and high in fiber, with energy content in a lignified form.
India, with 17.5% of the global population and 20% of the world’s cattle population, faces challenges due to limited land availability for agriculture. The country’s animal population grows at a rate of 0.66% annually, while the human population increases rapidly at 1.6%. With only 4% of cultivable land allocated to farm feed production, there is intense competition between human and animal populations for food and fodder resources. India currently experiences a deficit of 44% in concentrate feed ingredients, 10.5% in dry crop residues, and 35.6% in green fodder, exacerbating the shrinking farmland due to urbanization.
Traditional feed in India consists of crop residues or straw from grains like jowar, bajra, ragi, wheat, and barley, either whole or ground. These materials can be fed alone or in combination with fresh fodder. The limited availability of land for fodder crops necessitates the exploration of non-traditional or

Introduction
Sexual development in animals is considered one of the most complex research areas. This complexity arises from the underlying genetic structures that determine gender. Additionally, sexual development is viewed as one of the most intricate traits that have evolved, making it essential to studying evolution and population genetics (Schartl et al., 2018). According to evolution, fish have a link between invertebrates and higher-stacked vertebrates. According to Smith & Wootton, (2016), Kang et al. (2017), nearly all known mechanisms of sex determination observed in vertebrates have been identified in fish. As a result, finding the fish sex determination genes and their role in fish biology has excellent significance for the purely biological science of sex determination in animals. The energy from food is consumed into growth before fish become sexually mature. Since there is a range of ages for sexual maturity among different fish species, this explains the bilateral sexual growth differences in the species. The common carp (Cyprinus carpio) and the half-smooth tongue sole (Cynoglossus semilaevis) are two species that show a pattern in which females mature later than males, leading to larger females.
Sex-determining genes and their action mechanisms are crucial for guiding sex control breeding strategies in animals like the Nile tilapia (Oreochromis niloticus) and yellow catfish (Pelteobagrus fulvidraco), where males are categorized as more advanced than females Shao and Chen 2012; Chen et al., 2013; Long et al.., 2015; Mei and Gui. 2020). However, over ten years ago, the most evolved animals were the primary research subjects on the genes that determine sex and the mechanisms by which they work. According to Sinclair et al., SRY, also known as Sinclair, is the first human sex-determining gene found on the Y chromosome. in mice) and subsequently turned out to be a gene that determines maleness.

Introduction
Chromosome manipulation, the targeted alteration of chromosome quantity and combination, represents a cornerstone of genetic enhancement in aquaculture. Initially rooted in early twentieth-century studies focused on fundamental biology—particularly in amphibian models—this field has significantly expanded to enhance desirable traits through methods like polyploidy and uniparental inheritance (Arai, 2001; Benfey, 1999; Benfey, 2011; Cherfas, 1975; Devlin & Nagahama, 2002; Felip et al., 2001; Guo et al., 2009; Hulata, 2001; Komen & Thorgaard, 2007; Nagy, et al., 1979; Nagy, et al., 1978; Neyfakh, 1956; Ojima & Makino 1978). Over time, researchers worldwide have meticulously refined these techniques, transforming chromosome manipulation into a powerful tool for developing aquaculture strains with improved performance traits. By the late 20th century, aquaculture research began leveraging chromosomal modifications in finfish and aquatic invertebrates to achieve increased growth rates, disease resistance, and enhanced survival, with such techniques becoming extensively applied in commercial aquaculture operations (Pandian & Koteeswaran, 1998; Piferrer et al., 2009; Purdom, 1972). Over the past 30 years, a wide body of research has focused on optimizing treatment conditions specific to each target species, yielding robust evaluations of various aquaculture performance metrics. These metrics, including survival, growth, reproductive maturation, and disease resistance, have proven essential in assessing the effectiveness of polyploid and uniparental (gynogenetic and androgenetic) progeny (Purdom, 1976; Refstie et al., 1977; Romashov et al., 1960; Romashov & Belyaeva 1964; Stanley 1976; Stanley, 1976; T. J. Pandian, 2011; Devlin & Nagahama 2002; Guo, et al., 2009; Hulata, 2001; Komen & Thorgaard, 2007). As aquaculture has grown into the fastest-expanding sector of animal food production globally, the demand for sustainably produced, high-quality protein continues to rise. This surge in demand is driven, in part, by the decline of global fisheries due to overfishing, pollution, and habitat degradation. Consequently, the aquaculture industry faces the challenge of increasing output sustainably, necessitating the development of improved fish strains that support the resilience and efficiency of farmed stocks. To meet these demands, a range of genetic modification methods has been employed, aiming to produce fish with desirable traits such as rapid growth, superior meat quality, and enhanced resistance to disease (Xu et al., 2015). Chromosome manipulation has thus emerged as a critical tool, facilitating precise genetic interventions to enhance farmed species’ overall performance and adaptability.

Introduction
Fisheries and aquaculture are crucial for global food security, providing a significant portion of the world’s animal protein supply. With the rapid growth of the human population and the overfishing of natural fish stocks, it is more important than ever to increase aquaculture production sustainably. Advances in molecular cytogenetics are crucial for promoting sustainable growth and innovation in fisheries and aquaculture. These advancements offer deeper insights into the genetic factors that govern key traits like growth, reproduction, and environmental resilience, enabling aquaculture to address global food demands while safeguarding biodiversity and maintaining genetic
integrity. The integration of these techniques in fisheries and aquaculture has led to significant advancements in the genetic improvement of cultured species, disease management, and biodiversity conservation in recent years. Moreover, these scientific advancements offer innovative methods for effective disease control and the preservation of aquatic biodiversity, all of which contribute to aquaculture’s long-term viability and growth. Over the past two decades, fish karyotype studies have been combined with genome sequencing, revealing more remarkable genome plasticity and variability in fish compared to other vertebrates. Comparative fish genome analysis evaluates divergence rates and explores sex-determination genes and gene family evolution in teleosts. ,Currently, over 80 fish species have their genomes annotated in the Ensembl database (https: //www.ensembl.org/index.html, accessed on 6 April 2021), and around 150 are assembled to the chromosome level in the NCBI database (https://www.ncbi.nlm.nih.gov/genome/). However, the quality of many assembled genomes has been criticized for not meeting reference genome standards. Fish genome sequencing is expected to grow significantly by 2028 due to initiatives such as the Earth BioGenome Project. This chapter will explore the chronological development of cytogenetic techniques used in aquaculture and fisheries, emphasizing their role in improving quality, ensuring disease resistance, and promoting environmentally sustainable practices.

Earth’s atmosphere is a dynamic and complex system that plays a crucial role in supporting life as we know it. This chapter explores into the fascinating world of this gaseous envelope that surrounds our planet, exploring its composition, structure, and the processes that drive both our daily weather and long-term climate. It includes:
• Composition and Structure: It will begin by examining the unique blend of gases that make up the atmosphere, including nitrogen, oxygen, argon, and trace amounts of others. It will also be explored how the atmosphere is structured into distinct layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere), each with its own characteristics and role.
• Weather: Weather refers to the short-term conditions of the atmosphere at a specific time and place. We’ll discuss the key elements of weather, such as temperature, pressure, humidity, wind, and precipitation, and how they interact to create the ever-changing weather patterns we experience.
• Climate: In contrast to weather, climate describes the long-term average of atmospheric conditions in a particular region. We’ll investigate the factors that influence climate, including latitude, altitude, proximity to oceans, and atmospheric circulation patterns. We’ll also explore the different climate zones found across the globe.
• Interconnectedness: A key focus of this chapter understands how weather and climate are interconnected. Daily weather patterns are influenced by the same fundamental atmospheric processes that shape long-term climate. For example, the way the sun’s energy interacts with the atmosphere drives both daily temperature variations and global climate patterns.

Horticulture, the branch of agriculture that deals with the art, science, technology, and business of cultivating plants, plays a vital role in food security, nutrition, and economic development globally. This diverse sector encompasses a wide array of activities, broadly categorized into:
• Pomology: The cultivation of fruits and nuts.
• Olericulture: The cultivation of vegetables.
• Floriculture: The cultivation of ornamental flowering plants.
• Landscape Horticulture: The design, construction, and maintenance of landscapes.
• Post-harvest Handling: The management of horticultural produce after harvest to maintain quality and reduce losses.
Each of these components is intricately linked with weather conditions, making the horticulture sector highly vulnerable to climate change.

1. Introduction
Aquaculture, the farming of aquatic organisms such as fish, crustaceans, mollusks, and aquatic plants, plays an essential role in global food security and economic development. As the demand for sustainable and efficient fish farming practices grows, the need to optimize fish health, growth, and feed efficiency becomes increasingly crucial. One emerging area of interest in aquaculture nutrition is the use of bioactive peptides, which offer a natural and effective alternative to synthetic feed additives.
Bioactive peptides are short chains of amino acids, typically ranging from 2 to 20 residues, which are derived from protein sources. These peptides are typically inactive within the parent protein but become bioactive once they are released through specific processes, including enzymatic hydrolysis, microbial fermentation, or gastrointestinal digestion. The peptides exhibit a wide range of biological activities that can directly benefit fish and shellfish health. Their functional properties include antimicrobial, antioxidant, immunomodulatory, antihypertensive, and growth-promoting activities, making them valuable components of aquafeeds.
The integration of bioactive peptides into aquaculture systems offers an innovative and environmentally sustainable approach to enhancing the health and performance of aquatic species. By replacing or complementing conventional feed additives, such as antibiotics and synthetic growth promoters, bioactive peptides can improve feed efficiency, disease resistance, and immune function, thereby promoting better overall productivity.

1. Introduction
Enzymes are specialized proteins that act as biological catalysts, facilitating and accelerating biochemical reactions within living organisms. They are essential for various physiological processes, including digestion, metabolism, and energy production. In fish and other aquatic animals, enzymes play a pivotal role in breaking down complex nutrients found in their diets into simpler, absorbable components. This enzymatic action is vital for maximizing nutrient utilization, promoting growth, and ensuring overall health. The inclusion of enzymes in aquaculture feeds has garnered significant attention over recent years, particularly as the industry strives to meet the increasing global demand for fish and seafood products. With aquaculture now accounting for over 50% of the fish consumed worldwide, there is an urgent need for innovative strategies that enhance the sustainability and efficiency of fish farming operations. One such strategy is the supplementation of feeds with exogenous enzymes, which has been shown to improve feed digestibility, promote better growth performance, and mitigate environmental impacts associated with aquaculture.
1.1. The Role of Enzymes in Nutrient Digestion
Fish diets often consist of a combination of protein, carbohydrates, and lipids sourced from both animal and plant materials. However, many of these feed ingredients, especially plant-based sources, contain complex macromolecules that can be difficult for fish to digest. Fish possess a limited capacity for endogenous enzyme production, which can hinder their ability to effectively break down these complex nutrients. As a result, poorly digested feed not only leads to inefficient nutrient absorption but also contributes to increased waste production, further exacerbating water quality issues in aquaculture systems.

Introduction
Over the past few decades, fisheries nutrition has undergone a remarkable transformation, driven by the rapid expansion of global aquaculture and the increasing need for sustainable seafood production. As wild fish stocks have become overexploited and the demand for protein-rich aquatic food sources continues to rise, aquaculture has emerged as a vital solution for meeting the growing global need for fish and seafood. By 2014, aquaculture production had surpassed wild-caught fisheries in providing fish for human consumption, marking a significant shift in how we obtain seafood. This growth, however, brings with it numerous challenges, particularly regarding the nutrition of farmed fish.
Fisheries nutrition, as a specialized field, plays a pivotal role in supporting aquaculture’s ability to provide healthy, high-quality fish for human consumption while maintaining environmental balance. As aquaculture intensifies, the demand for high-quality, cost-effective feed ingredients has surged. Traditional reliance on marine-derived ingredients like fishmeal and fish oil is becoming increasingly unsustainable, as these resources are finite and face depletion due to overfishing. This has resulted in rising costs for these inputs, placing economic pressures on aquaculture producers. Additionally, marine-derived ingredients contribute to ecological imbalances, prompting the need for alternative solutions in feed formulation.
At the same time, the environmental impacts of aquafeeds have garnered increased scrutiny. The production of feed ingredients such as soybeans, corn, and other crops can contribute to deforestation, water pollution, and greenhouse gas emissions, undermining efforts to achieve environmental sustainability in aquaculture. Nutrient waste from uneaten feed and fish excreta can also lead to eutrophication in aquatic ecosystems, damaging water quality and biodiversity. Therefore, fisheries nutrition must address not only the nutritional requirements of fish but also the broader ecological footprint of aquafeed production and usage.

This alternative pathway for glucose oxidation has enzymes in the cytosol through which glucose is degraded to carbon dioxide. It is also called a shunt because carbon atoms from glucose 6-phosphate take a long route before they proceed down the EMP or glycolytic pathway. This pathway is anabolic in nature as it produces many intermediates. In this pathway, two NADPH are generated from one glucose 6-phosphate molecule. No ATP is generated or consumed.
Overall, this pathway needs three glucose-6-phosphate molecules to complete all the reactions. Therefore, one cycle run produces 2 mol of fructose-6- phosphate, 1 mol of glyceraldehyde-3-phosphate, and 3 mol of carbon dioxide from 3 mol of glucose-6-phosphate with the reduction of 6 mol of NADP+ to NADPH.
Overall reactions of the HMP pathway are as follows:
3 Glucose-6-P + 6 NADP+→ 3 ribulose-5-P + 3 CO2 + 6 NADPH
3 Ribulose-5-P → 2 xylulose-5-P + Ribose-5-P
2 Xylulose-5-P + Ribose-5-P → 2 fructose-6-P + Glyceraldehyde-3-P

CALIBRATION OF SEED DRILL
Calibration of a seed drill refers to the process of testing the seed drill to ensure it delivers the correct seed rate. Before using the seed drill in the field, calibration is essential to achieve the desired seed rate. This procedure is done to ensure that the machine delivers the predetermined seed rate accurately. The following steps are followed for the calibration of a seed drill.
Procedure for Calibration of a Seed Drill
• Determine the nominal width (W) of seed drill .
W = M x S,
Where, M = Number of furrow openers
S = Spacing between the openers, m
• Find the length of the strip (L) having nominal width (W) necessary to cover 1/25 ha (1 /25 x 10000 m2).
L = 400/W meter
• Determine the number of revolutions (N) of the ground wheel of the seed drill
required to cover the length of the strip (L).

Abstract
Managing weeds in agricultural productivity poses a formidable challenge. An increasingly common weed control strategy in ecologically friendly farming systems is integrated weed management, which involves bioherbicides. Ensuring global food security and environmental safety heavily relies on the sustainability of agricultural production. Worldwide, sustainable agricultural approaches, including the maintenance of a permanent layer of soil cover, the minimization of soil disruption, the implementation of regular crop rotations, the practice of integrated weed control, and the adoption of conservation agriculture, are becoming increasingly popular. Bio-herbicides are commonly derived from plants containing phytotoxic allelochemicals or specialized bacteria that can induce diseases and reduce the population of weeds within a given area. However, bio-herbicides have demonstrated significant potential in inhibiting the germination and spread of weed seeds. Bio-herbicides offer a promising, environmentally friendly, promising solution for weed control, as they are derived from natural sources such as bacteria, plants, or biochemical compounds. This study investigates the effectiveness, environmental benefits, and challenges of using bio-herbicides to achieve sustainable weed control. Bio-herbicides possess the capacity to reduce dependency on artificial pesticides, eradicate unintended harm to non-target organisms, and foster a more harmonious ecosystem by employing biological agents to target particular weeds selectively.
Keywords: Bio-herbicide, allelochemicals, weeds, sustainable agriculture.

Introduction
The Kashmir Valley, located on the northern side of the Indian subcontinent, is renowned for its stunning aquatic habitats, integral to its biodiversity and cultural heritage. The state is endowed with natural water resources Exclusively Distributed by NIPA GENX Electronic Resources and Solution Pvt. Ltd. New Delhi encompassing a total water spread area of about 0.40 lakh hectares (Department of Fisheries, Government of Jammu and Kashmir). These resources exist in the form of fast-flowing cold-water streams, lakes, rivers, marshes, springs, and high-altitude lakes. These waters hold great potential for the development of various types of fisheries, including cold water fisheries, warm water fisheries, sport fisheries, and reservoir fisheries (Department of Fisheries, Government of Jammu and Kashmir). The data outlining the fishery resources of Jammu and Kashmir is presented in (Table 1). The state is blessed with the presence of significant rivers, namely the Indus, Jhelum, Chenab, and Ravi (Shukla and Ali, 2018). Indus originates from Lake Mansarovar at an elevation of 5100 meters in the Himalayas and flows diagonally toward the northwest (Ahmad and Rais, 1998). Jhelum, another important river, originates from a spring at Verinag, which lies northeast of Anantnag Town. The river flows through the city of Srinagar and the towns of Sumbal, Sopore, and Baramulla (Raina, 2002). The third major river in the state is the Chenab, which originates from the Himalayas. The lakes of the Kashmir Valley are surrounded by the majestic Himalayan Mountains (Romshoo et al., 2020). These lakes are invaluable natural water bodies housing a diverse gene pool. The valley boasts numerous lakes and wetlands at varying altitudes, categorized as high-altitude lakes (such as Gangabal, Vishan Sar, Kishan Sar, Sheesh Nag, Nilnag, Kauser Nag, etc.) and valley lakes (including Wullar, Dal, Manasbal, Aanchar, Ahansar, Hokersar, Haigam, etc.). The main factors contributing to the degradation of the lakes include indiscriminate cutting of surrounding vegetation, leading to increased silt and nutrient accumulation in the lake. Additionally, the disposal of sewage and domestic waste, along with the excessive use of pesticides and insecticides in the surrounding areas, and agricultural practices utilizing agrochemicals have been identified as significant contributors (Jamal et al., 2022; Kumar et al., 2022).

Introduction
The Kashmir Valley, situated in the western Himalayas between latitudes 33°01'N and 35°00'N and longitudes 73°48'E and 75°30'E, spans an area of 4,920 square kilometers and sits at an elevation of 1,585 meters. This region is rich in water resources, featuring numerous lakes, rivers, and wetlands. The ecosystem benefits from a continuous supply of water from perennial glaciers, mountain streams, and a multitude of springs. It is estimated that more than Exclusively Distributed by NIPA GENX Electronic Resources and Solution Pvt. Ltd. New Delhi 6% of Kashmir's land surface is covered by various types of water bodies, enhancing the valley's natural beauty (Zutshi and Gopal, 2000). Whether from glaciers, springs, rivers, or lakes, the water in Kashmir contributes significantly to its picturesque landscape. The Kashmir Valley hosts a variety of 23 fish species, both native and introduced (Bhat et al., 2020). Cypriniformes, the largest group of freshwater fish, are divided into two main superfamilies: Cyprinoidea (carp like fishes) and Cobitoidea (loach fishes). This classification covers a wide variety of aquatic species, highlighting the extensive biodiversity within the Cypriniformes order (Nelson et al, 2016). The initial documentation of cold-water fish in India was provided by Hamilton in 1822. The Cobitidae family, known as true loaches, includes species such as Botia birdi found in the Kashmir Valley. The family Balitoridae, specifically the subfamily Nemacheilinae, in this region include two scaleless fish species earlier named as Cobitis vittata and C. marmorata by Heckel (1838) but Kullander et al. (1999) renamed them as Triplophysa marmorata and T. kashmirensis and Paraschistura punjabensis. Loaches are a fascinating subject for aquatic enthusiasts and researchers alike. Found predominantly in Eurasian waters, these bottom-dwelling fish are recognized for their distinctive elongated bodies, small scales, and barbels around the mouth which aid in their sensory and feeding functions. Loaches are renowned for their adaptability, thriving in a variety of habitats ranging from fast-flowing rivers to stagnant ponds. With over 200 species classified across several genera, loaches exhibit a remarkable range of behaviours and ecological roles, from the well-known clown loach (Chromobotia macracanthus), popular in the aquarium trade, to the stone loach (Barbatula barbatula), a species integral to the ecosystems of European rivers and streams (Nelson, 2006; Kottelat, 2012). Loaches play significant roles in their natural habitats, contributing to the benthic community dynamics and nutrient cycling. Their sensitivity to environmental changes makes them valuable bioindicators for assessing the health of freshwater ecosystems (Kottelat & Freyhof, 2007).

Introduction
An organism can be highly destructive in one habitat while coexisting peacefully in another. It is exceedingly challenging to forecast the impact of a new species on the local flora and fauna when it is brought into an ecosystem where it has never before lived naturally. In competition for resources and space, the imported species can surpass the native fauna. A delicate web of interdependence that gradually shaped over thousands of years is harmed when introduced species compete more successfully for resources because they have no predators in the area. In certain cases, they even kill and eat native populations (Raman et al., 2013). Fish species classified as non-native are those that have been intentionally introduced outside of their natural range (for example, to support aquaculture, improve a reservoir or recreational fishery, through the ornamental fish trade, or to control mosquitoes), accidentally introduced (for example, through bait releases, aquaculture escapes, or ballast water transport (Gupta and Everard, 2019), or introduced in the name of wellmeaning but misguided religious practices (Everard et al., 2019). Due to their higher birth rate, the tendency to feed on local fish species, increased growth rate, larger size, longer life spans, or competition for comparable food supplies and habitat, these species may negatively impact native fish species (Ricciardi and Rsmussen, 1998).
The International Union for Conservation of Nature and Natural Resources (IUCN) classifies alien invasive species as those that spread quickly through natural or semi-natural ecosystems or habitats, act as change agents, and endanger the biological diversity of the host species. These invasive are widely dispersed across the world's ecosystems, including every class of living thing (Raghubanshi et al., 2005). Fish native to the area compete with exotics for food and habitat. The quality of the aquatic ecosystems may deteriorate, new illnesses and parasites may be introduced, hybrids may be produced, native fish may be killed, and genetic "pollution" may occur. All of these will eventually cause the priceless biodiversity to disappear (Nyman, 1991). The socioeconomic facets of the human population that depend on aquatic environments for survival are also at danger, in addition to possible consequences on the quantity or quality of biodiversity (Philipp et al., 1995). The most varied group of vertebrates is fish, and freshwater fish in particular are thought to be among the most critically threatened animal species due to the introduction of alien (or non-native) species, which are species that do not typically occur in an aquatic environment (CONABIO, 2008). According to Contreras-Balderas (1999), these species hurt local populations when they are introduced and harm ecosystems by causing the water body to deteriorate. Maclvor brought the first group of exotic fish in 1874, namely crucian carp

Three fundamental aspects—slope, stream order, and land use/land cover (LULC)—are critical in understanding landscape dynamics. These factors shape the physical and hydrological characteristics of an area and significantly impact ecological functions, land development planning, and conservation initiatives. Reliable analysis and detailed mapping of these parameters are crucial for the responsible management of land and water resources.
Operation and maintenance of soil conservation structures encompass a variety of activities designed to reduce soil erosion, sustain soil quality, and enhance water absorption. Structures such as terraces, check dams, and gully plugs must be consistently monitored and managed to ensure optimal performance over time. Essential tasks include frequent assessments, clearing of blockages or sediment build-up, and timely repairs to safeguard their structural integrity and operational efficiency.
Soil conservation refers to a collection of methods aimed at preserving soil from erosion and deterioration. At its core, soil conservation recognizes the soil as a living, dynamic system. One of its primary principles is the regular return of organic material to the soil, supporting its biological activity and overall health. Soil conservation can be compared to preventive maintenance on a car. Just like changing the oil, replacing filters, and inspecting spark plugs helps avoid costly engine damage, taking proactive steps to conserve soil now ensures its long-term productivity and health. Preventive measures in soil conservation help safeguard this essential resource for future use.
Soil conservation is a “combination” of practices used to protect the soil from degradation. At its core, it involves recognizing soil as a vibrant, living ecosystem.
The countless organisms residing in the soil contribute significantly to its fertility and structure. These organisms decompose organic materials, release essential nutrients, and create pathways for air and water movement—crucial for soil health

Warehousing is a critical national strategy for conserving food grains. The proper storage and maintenance of notified commodities, primarily food grains, alongside safeguarding them from adverse weather, rodents, and natural decay, are vital for fostering the growth and development of the agricultural sector.
Post-harvest losses contribute to approximately 10% of total food grains, primarily due to improper storage methods, insects, rodents, microorganisms, and birds. The Punjab State Warehousing Corporation (PSWC) takes on the responsibility of storing, handling, and warehousing notified commodities, including agricultural produce, industrial raw materials, finished goods, and various perishable and hygroscopic items. PSWC provides scientifically designed warehouses that protect both the quality and quantity of stored goods, aided by trained personnel.
At PSWC warehouses, stored products are safeguarded from rodents, pests, and moisture, ensuring their preservation. The provision of scientifically managed storage facilities for food grains, from procurement to distribution, is a vital function carried out by PSWC. PSWC has made significant strides in creating warehousing facilities throughout the state, constructing numerous warehouses in key rural and urban areas.
Rail-side warehousing facilities have also been established, offering costeffective and efficient storage solutions under a unified approach. Additionally, PSWC helps prevent distress sales, enabling producers to hold their products until favorable market conditions arise, thereby securing the best possible value for their goods.
Horizontal sheds are commonly used to offer low-cost, large-volume storage, and the Food Corporation of India (FCI) has also built very large sheds for storing grains and other products. These sheds typically feature steel or corrugated sheet

Quality control plays a vital role in ensuring food safety and freshness. Inspecting, testing, and grading fruits and vegetables is essential to confirm that food products meet safety standards. In today’s globalized food industry, quality control tests are conducted at various stages throughout the supply chain, from cultivation and harvesting to processing, packaging, transportation, and distribution.
In agriculture, the quality of grain is determined by its intended use. In ethanol production, factors such as starch content are crucial, while in food and feed manufacturing, properties like protein, oil, and sugar are of primary importance. In the milling industry, the soundness of grain is the most significant factor in determining its quality. For grain farmers, high germination percentages and seed dormancy are essential characteristics to monitor. For consumers, visual qualities such as color and flavor are key indicators of quality. Quality control ensures that the grain meets the needs of both producers and consumers while maintaining food safety.
RESOURCES FOR QUALITY CONTROL
PRE-HARVEST TESTING
Pre-harvest tests are essential tools that help growers assess the needs of their crops. These tests assist in making informed decisions regarding nutrition or pesticide applications, determining the optimal harvest windows, and supporting various farm management decisions. By conducting pre-harvest testing, farmers can enhance crop health, improve yields, and ensure that their crops are ready for harvesting at the best possible time.
Starch Iodine Test
Starch is a carbohydrate present in various plants, including apples. As apples ripen, the starch gradually converts into sugar. The amount of starch in an apple

Introduction
A biogas plant is an engineered system designed to generate biogas through the anaerobic digestion of organic materials rich in cellulose, such as cow dung, agricultural residues, poultry waste, and other biodegradable biomass. In the absence of oxygen, microorganisms decompose these materials, producing a mixture of methane (CH4), carbon dioxide (CO2), and traces of hydrogen sulfide (H2S). This biogas can be utilized as a renewable energy source for cooking, heating, and power generation.
In India, cow dung has traditionally served as the primary substrate, and such systems were popularly known as Gobar Gas Plants. The early designs were promoted by the Khadi and Village Industries Commission (KVIC)
Components of a Biogas Plants
A typical biogas plant consists of the following major components:
• Foundation: Provides structural support to the digester and gas holder.
• Digester (Fermentation Tank): The main chamber where anaerobic digestion occurs.
• Gas Holder (Masonry Dome or Drum): Collects and stores the biogas produced.
• Mixing Tank: Used to prepare the slurry by mixing feedstock with water (commonly 1:1 ratio).
• Inlet Chamber/Pipe: Feeds the prepared slurry into the digester

In the contemporary academic sphere, the demands placed upon faculty members have grown increasingly complex, requiring a multifaceted skill set that goes beyond subject matter expertise. A truly effective faculty body is characterized by several key attributes and supported by institutional mechanisms that foster growth and accountability.
7.1. Effective Mentorship
• The Indispensable Nature of Communication Skills: Exceptional communication skills form the bedrock of effective teaching and mentorship. Faculty must possess the ability to articulate complex ideas with clarity and precision, adapting their communication style to suit diverse learning needs and preferences. This includes not only lucid lecturing but also active listening, providing constructive feedback, facilitating engaging discussions, and utilizing various communication technologies effectively (Fig.7.1). Strong communication fosters a positive and inclusive learning environment, enabling students to grasp concepts more readily, ask pertinent questions, and feel comfortable expressing their thoughts and challenges. Moreover, effective communication extends to interactions with colleagues, administrative staff, and parents, ensuring a cohesive and collaborative educational ecosystem.
• Unwavering Commitment to Student Welfare: Faculty commitment to student welfare transcends the traditional boundaries of academic instruction. It encompasses a genuine interest in the holistic development of students, encompassing their academic progress, personal growth,

Introduction
Liposomal drug delivery methods have received a lot of interest in the pharmaceutical industry because of their capacity to improve therapeutic efficacy while also reducing toxicity of encapsulated pharmaceuticals. Liposomes, which are spherical vesicles made up of lipid bilayers, provide targeted delivery of drugs, increased bioavailability, and controlled release of therapeutics (Gupta et al., 2023; Rana et al., 2023; Salave et al., 2023, 2024). However, guaranteeing the sterility of liposomal formulations is critical for their safety and efficacy, particularly in parenteral applications.
Sterilization is a validated process that achieves a microorganism-free product without altering its properties. In the pharmaceutical industry, a sterilization process is deemed valid when it successfully attains the necessary Sterility Assurance Level (SAL) of 10-6. The SAL represents the likelihood of contamination occurring after the sterilization process for a product with an initial biological load of 106 colonyforming units (Woedtke et al., 2008). The biological indicator used in this case is one of three bacterial species: Geobacillus stearothermophilus, Bacillus pumilus, or B. atrophaeus (Mcevoy et al., 2023). Accordingly, a product may be deemed “sterile” if the likelihood of a viable microorganism being present is equal to or less than 106. Liposomal formulations provide particular issues for sterilization due to their fragile nature and the physicochemical features of the encapsulated drugs. Sterilization plays a vital role in the production of liposomal formulations for parenteral administration. It is crucial to remove all viable microorganisms to prevent infections, maintain the effectiveness of therapeutic agents, and ensure patient safety. The delicate nature of liposomal carriers presents unique challenges in the sterilization process (Lombardo et al., 2022 a).
Traditional sterilization methods, such as autoclaving, dry heat, and chemical sterilization, are frequently not suitable for liposomal structures (Figure 1). The application of these techniques can lead to the breakdown of lipids, changes in phase, or destabilization of the drug contained within the formulation, resulting in a decrease in its therapeutic effectiveness (Zuidam et al., 1993 a). In addition, the physicochemical properties of liposomes, such as their size, lamellarity, and lipid composition, play a crucial role in determining their stability and how they react to sterilization methods.
Considering these limitations, the pharmaceutical industry has investigated alternative methods of sterilization that guarantee the elimination of microorganisms while preserving the integrity of liposomes. A commonly used method for sterilizing liposomal formulations is filtration through sterile membrane filters with pore sizes of 0.2 micrometers (Goldbach et al., 1995 a). This

Introduction
Liposomal formulations have emerged as a revolutionary platform in drug delivery systems, significantly enhancing the therapeutic efficacy and safety profile of numerous pharmaceutical agents (Crommelin et al., 2015). Liposomes are spherical vesicles composed of lipid bilayers, providing a versatile and biocompatible method for encapsulating both hydrophilic and hydrophobic drugs (Nsairat et al., 2022) (Liu et al., 2022). This encapsulation protects drugs from degradation, reduces systemic toxicity, and enhances their bioavailability (Gubernator, 2011). Beyond their protective capabilities, liposomes serve as an effective platform capable of delivering a diverse array of therapeutic agents, including conventional drugs, proteins, genes, and oligonucleotides (Gupta et al., 2023) (Salave et al., 2022 a) (Juliano et al., 2009). Their attractive biological properties, such as biocompatibility, enhanced solubility of hydrophobic compounds, stability of large molecules, and improved efficacy, position them as ideal candidates for advanced drug delivery systems. These properties enable precise targeting and controlled release strategies, thereby optimizing therapeutic outcomes across various medical applications (Polaka et al., 2021). The pharmacokinetic (PK) and pharmacodynamic (PD) properties of liposomal formulations are crucial determinants of their clinical success. Pharmacokinetics involves the study of the absorption, distribution, metabolism, and excretion (ADME) of drugs, while pharmacodynamics focuses on the biochemical and physiological effects of drugs and their mechanisms of action (Li et al., 2019) (Negus et al., 2018). Understanding these parameters in the context of liposomal delivery is essential to optimize therapeutic outcomes and minimize adverse effects.
Liposomal encapsulation can significantly alter the PK profile of a drug. By modifying drug release kinetics, liposomes can extend the half-life of encapsulated agents, ensuring sustained therapeutic effects and reducing dosing frequency (Rana et al., 2022). Moreover, the ability of liposomes to target specific tissues or cells through passive and active targeting mechanisms enhances drug distribution to the site of action, increasing efficacy and minimizing off-target effects (Salave et al., 2021)(Salave et al., 2022 b). For instance, the liposome surface can be covalently decorated with targeting ligands, enhancing binding and internalization by cancer cells that express receptors for these ligands (Riaz et al., 2018). These ligands can include immunoglobulins or their subunits, such as immunoglobulin fragment antigen binding (Fab’) and single-chain variable fragments (scFv), or nutrient molecules with affinity for cell surface receptors, such as transferrin and folate (Sapra et al., 2003) (Kang et al., 2011) (Cheng et al., 2010). Liposomes’ unique structural properties facilitate the incorporation of targeting ligands, pHsensitive components, and other modifications to refine the drug’s therapeutic profile (Salave et al., 2022 c)(Salave et al., 2023)(Zangabad et al., 2018). They can also be engineered to release encapsulated drugs at specific sites by sensitizing the bilayer membrane to stimuli such as light exposure, oxidation, enzymatic degradation, heat, or radiation (Lee et al., 2017) (Antoniou et al., 2021). The

Introduction
DNA fingerprinting envisages a very significant molecular methodology employed for identification and characterization of wheat varieties and germplasm. It is of utmost importance in varietal authentication, rights protection of breeders, and analysis of genetic diversity. Currently employed molecular markers like SSRs, SNPs, and DArT are applied extensively for wheat fingerprinting. Such markers precisely differentiate closely related varieties and aid in breeding programs (Babu et al., 2020; Kiss et al., 2021).
The current standing of wheat DNA fingerprinting shows a trend toward high-throughput genotyping and genomic selection strategies to accelerate crop improvement. Future prospects would entail the integration of advanced sequencing technologies such as Next-Generation Sequencing (NGS) and machine learning for genetic analysis. These technologies will ease wheat breeding and dramatically contribute to food security and climate-resilient agriculture. Expanding the global DNA fingerprinting database would further enhance global wheat germplasm conservation and utilization (Sandhu et al., 2021; Ahmadi et al., 2020). Wheat (Triticum spp.) is one of the major staple crops of the world, supporting the sustenance of over one-third of the total world population. It is the main source of carbohydrates, proteins, fibers, and other important micronutrients, making it very important for human nutrition. Wheat is cultivated mainly in all types of agro-climatic zones, with major producers being China, India, Russia, United States, and the European Union.
Wheat is highly valuable not only in terms of food security, but also economically with millions of farmers involved in its production and trading worldwide. Wheat is an important raw material for many food products, such as bread, pasta, and baked goods. Wheat production faces challenges from climate change, pests, and emerging pathogens. Therefore, continuous research on wheat, genetic improvement for desirable traits, and sustainable agricultural practices are needed to enhance yield, resilience, and in turn global food security. Genetic diversity in wheat is pertinent for fulfilling food security at the global level and for the success of breeding programs, apart from giving diverse traits for resistance against pests, diseases, and environmental stresses like droughts

1. Introduction
Soils stand out as an intricate and diverse ecosystem on our planet. Their significance extends beyond supplying 98.8% of the world’s food, encompassing a wide array of essential services such as carbon storage, regulation of greenhouse gas emissions, flood prevention, and offering support to burgeoning urban populations. However, it is crucial to recognize that soil is a finite natural resource. The unprecedented growth of the human population, escalating from 250 million in the year 1000 to 6.1 billion in 2000, with projections reaching 9.8 billion by 2050, along with the intensified practices of agricultural production, is exerting immense pressure on the sustainability of soils.
For long-term sustenance the concept of ‘Soil quality’ was propagated around three decades back from now in the United States of America, and further expanded to the scientists of European and Asian countries. Soil health and soil quality are two interweaving term that signifies the potentiality or capacity of soil towards mankind. These two words complement each other in such a way that one term automatically comes with another to determine both aspects i.e. agricultural sustainability and environmental quality in terms of plant, animal and human health (Haberern, 1992; Doran, 2002). Idowu et al. (2007) remarked that the term “soil quality” is more favoured by scientists, whereas “soil health” is a term favoured by farmers as it connotes a holistic approach to soil management. The inception and application of soil quality term was officially approved by Soil Science Society of America (SSSA). They defined soil quality as “The capacity of a specific kind of soil to function within natural or managed ecosystem boundaries, to sustain biological productivity, maintain environmental quality, and promote plant and animal health” as illustrated by Karlen et al. (1997). It is a complex composition of certain properties associated with physical (texture, bulk density, water holding capacity, infiltration capacity etc.), chemical (pH, EC, organic carbon, extractable macronutrient and micronutrient etc.) and biological (microbial activity and related parameters) conditions of soil (Prabha et al., 2020). There are primarily two key methodologies for assessing soil quality: the descriptive approach, which focuses on characterizing various aspects or attributes of soil quality, and the Indicative approach, which aims to identify the ability or capacity of an attribute in a desired manner. The comprehensive process of developing a soil quality index is guided by the 3-Is framework: the Identification of indicators, Interpretation, and Integration of selected soil quality indicators. It is important to note that the specific set of indicators utilized can vary between different soils, diverse agroecosystems, and from one crop to another. Additionally, climatic conditions and other abiotic factors may also significantly influence the assessment of soil quality.
The USDA has categorized soil quality indicators into four primary groups: visual, physical, chemical, and biological indicators. However, in the current context, the dominant indicators are physical, chemical, and biological. For a systematic assessment of soil quality, it is crucial to collect individual parameters and integrate them meaningfully. Consequently, integrated soil quality indicators

1. Introduction
Ecosystem Services (ES) are actually the benefits human beings derive from their interaction with nature (Reyers et al., 2013; Ernstson, 2013). Around 400 BC, Plato observed how important service provided to Attica by the forests and subsequent loss of forests lead to drying spring and soil erosion (Mooney and Ehrlich, 1997). Thus, the work of Plato highlights that how the people were even then aware of the critical services provided by nature much before the industrial revolution (Rapidel et al., 2011). These ES are categorised into mainly provisioning, supporting, regulating and cultural services as per the Millennium Ecosystem Assessment (MEA, 2005). In fact, the increasing population warrants more and more set of ES (Biggs et al., 2015). A combination of factors responsible for delivery of ES like geology, climate, ecosystem, management scenarios, society, techniques, skills etc. that led to ES in an agricultural ecosystem (Kroll et al., 2012; Swinton et al., 2007). The ordinary nature largely comprised of agricultural lands (i.e., intensive crops, species poor, artificial pasture) that covers around 37.4% of total Earths’ land surface (FAOSTAT, 2016; Leff et al., 2004). Converting large tract of pristine lands into agricultural land and other competing uses considered to be one of the main reasons for biodiversity loss and land degradation (Tilman et al., 2001). Thus, meeting the challenge of working with limited arable land to feed our population in an eco-friendly manner requires our proper understanding of processes/mechanisms involved in nutrient availability/dynamics including fixation/ release pattern and refining the best management practices (Kumar et al., 2022a). The production of food has been targeted at the cost of other ES like supporting, cultural and non-marketable provisioning services (Muller et al., 2016; Foley et al., 2005; MEA, 2005). There is complex interaction between ecosystem and societal changes in an agricultural landscape. One is intermittently connected to other. Thus, it requires thorough understanding of the processes and biophysical factors that affect ES research, in particular and social-ecosystem, in general (Reed
et al., 2013; Carpenter et al., 2006; Plieninger et al., 2013). The ES that contribute to the agricultural production are mostly linked to aspect of soil fertility, biological control as well as pollination (Bommarco et al., 2013; Duru et al., 2015).

1. Introduction
Fish and fisheries remains to be an important sector for Indian economy providing food, nutrition as well as employment to a large share of the population. Initiating with a production of merely 7.7 lakh ton of fishes in 1951-52, the country was on its way of increasing the production steadily and has now attained the phenomenal success of producing 162.5 lakh ton during 2021-22. Of this total amount, 41.3 lakh ton has been obtained from marine fisheries and 121.2 lakh ton from inland resources (Anon, 2022). For the inland fisheries production, the contribution of fish culture sector was much lower than that from capture fisheries for several decades during the initial phases. However, the production of culture fisheries maintained a consistently increasing trend and has now surpassed in magnitude the production from capture fisheries sector (Fig.1). With the potential areas for fish culture being gradually used up for different purposes, maintaining such high production rates in coming days will be possible only through optimum management of various factors which govern the productivity of the ponds. Among such factors, one important aspect is nourishing the quality of pond soil and water.

1.1 Weather Forecasting
Farmers have always been at the mercy of the weather, and accurate forecasting has become an essential tool for their decision-making process. Weather forecasts play a critical role in supporting farmers’ decision-making processes, from crop planning and management to harvest planning and economic decision-making. Crop planning and management is one of the key areas where weather forecasts are crucial. Farmers use weather forecasts to determine the best time to plant seeds, taking into account temperature, moisture, and sunlight requirements. This enables them to choose crops that are suitable for the predicted weather conditions. Additionally, forecasts help farmers optimize irrigation, reducing water waste and ensuring crops receive adequate moisture (Fig.1.1).
Weather forecasts also help farmers mitigate weather-related risks. Extreme weather events like floods, droughts, heat waves, and storms can have devastating effects on crops. Accurate forecasts enable farmers to prepare for and respond to these events, reducing crop damage and loss. For instance, forecasts help farmers take measures to protect crops from frost and freeze damage, which can be catastrophic for certain crops.

Introduction
Plant breeding, according to Sansern et al. (2010), is the process of genetically altering plants to meet human demands. Prehistoric humans in various parts of the world domesticated only a small number of the hundreds of thousands of species that were then available. They did this by genetically altering these species’ components, which entailed both conscious and unconscious selection as well as differential reproduction of variants (Allard, 1999). A relatively small number of plant species have evolved over many years of trial and error to become the backbone of agriculture and, consequently, the world’s food supply (Mackay, 2001). This method of domestication includes the identification of specific valuable wild species along with a system of selection that resulted in alterations in the quality and quantity of cultivated crops.The modifications brought about by domestication involved altered organ size and shape, loss of many survival traits, such as bitter or toxic substances, the disintegration of seeds in grains protective structures, such as spines and thorns, seed dormancy, and change in life span increased for crops grown for roots or tubers and decreased for crops grown for seed or fruit. The domestication process followed mostly by mass selection (selection by bulking preferred kinds) is a potent method for facilitating quick changes while preserving genetic variability in the population (Okporie and Obi 2002).
Populations can exist in constantly changing surroundings due to genetic variation. More variation increases the likelihood that certain individuals in a group will have allele variants that are appropriate for the environment. Those individuals have a higher chance of survival to have offspring which carry that allele. Because of their success, the population will endure for additional generations. Selecting the best parents to utilize in artificial crosses is one of the key concerns for plant breeders since it encourages the expression of the largest genetic variability and the production of superior recombinant genotypes. The objective of plant breeding is to simultaneously improve all the desired traits. This task is complicated by correlations between various traits, which may result from pleiotropic genes, physical chromosomal links between genes, or population genetic structure. Choosing one feature will alter associated qualities, sometimes in a positive or in a negative way. As a result, selection may result in unexpected modifications, provided they fall within the typical range of variations seen in the crop and are therefore thought to be useful to consumers or the environment. Breeding practices in the 20th century improved a variety of genetic techniques, including methods for identifying and preserving more genetic diversity, creating variable populations for selection, and testing how to differentiate between the effects of genes and the environment. Naturally self-pollinating plants like soybeans or tomatoes, naturally cross-pollinated plants like maize, and plants whose vegetative propagation (typically cross-pollinated) allowed the direct fixing of improved types, all required different precise steps in the production process (Ubi, 2013).

Introduction
The genetic diversity of crops has been subjected to considerable humandriven selection throughout time, in particular, is often limited by conventional plant breeding techniques. Under these conditions, crops with low yields and a high risk of disease and pest infestation may be produced. Thus, there’s a need to introduce a technique where solutions to all the problems can be addressed. CIS breeding opens us a wider range of opportunities for improving crops by enabling the deliberate incorporation of natural genetic differences from closely related plants. The word “CIS” in CIS breeding means “on the same side/same kingdom”. CIS breeding is an advanced method for genetic improvement in which genes from closely related plants are inserted into the desired crop. This method creates crop varieties that are greatly improved in terms of growth capacity, yield potential and pest and disease resistance. CIS breeding is a pioneering technology designed to integrate novel traits into established crop varieties without the introduction of foreign genetic material. Utilizing the similar gene combinations and the plant’s intrinsic genetic systems, it is a natural form of genetic improvement that improves traits including yield, drought resistance, disease resistance and nutritional qualities (Anjanppa and Gruissem, 2021). Comparing to conventional breeding where gene transfer can occur through random cross- breeding or mutagenesis and risk of unintended effects are high, in CIS breeding, one or few genes are transferred from related species as well as risk of unintended effects are also low. Some countries, regulate it as conventional breeding and other regulate it as GMO breeding.

Introduction
Current state of global warming and climate change affecting crops through altered pest and disease incidence patterns, changes in temperature and CO2 levels which adversely affected the crop production (Habib-ur-Rahman et al. 2022). This threat is particularly pronounced in food-insecure regions, especially in Asian countries. Climate change not only jeopardizes crop and livestock health but also impacts soil and water resources and livelihood of rural communities. Furthermore, it contributes to food insecurity by increasing prices and reducing overall food production. The complexity of these effects highlights the need for modern agricultural techniques to mitigate risks and ensure global food security (Habib-ur-Rahman et al. 2018).
Crop improvement, an integral facet of agricultural development, remains a cornerstone in addressing the burgeoning global food demands. Conventional plant breeding methods have played a pivotal role in developing improved crop varieties that exhibit enhanced quality, higher yields and resilience to biotic and abiotic stresses. However, plant breeding methods involving continuous selection and intermating among closely related individuals can result in a reduction of genetic diversity within a cultivated crop species. The narrow genetic base makes crops more vulnerable to emerging threats, such as new pests or diseases and limits their ability to cope with changing climatic conditions. In India, the Green Revolution along with substantial plant breeding activities, led to a significant increase in crop yields, particularly in staple crops like wheat, rice and maize. However, one of the major consequences of green revolution is the development of narrow genetic base in cultivated crop species (Begna 2021).
Moreover, the reliance on a narrow genetic base, a consequence of crossing only two parents, curtails the exploration of broader genetic diversity. This limitation restricts the potential for effectively combining and expressing desired traits in the resulting crop varieties. Most of conventional plant breeding techniques were primarily focused on monogenic traits, while many agronomically important traits are quantitative in nature, controlled by polygenes, and influenced by the environment. This poses challenges for breeders relying only on phenotypic selection. Notably, traits influenced by multiple genes, such as resistance to diseases or tolerance to environmental stresses, are particularly challenging to manipulate using traditional breeding methods.
Quantitative trait loci (QTLs) are genomic regions that influence polygenic traits, first described by Geldermann (1975). Identifying QTLs associated with improving yield and quality traits is pivotal for catalysing a new Green Revolution (Arrones et al. 2020; Pradhan et al. 2015). Marker-assisted selection (MAS), introgression breeding and QTL pyramiding offer efficient avenues for developing improved cultivars. However, identifying QTLs associated with quantitative traits remains a challenge for plant breeders (Arrones et al. 2020). The basic requirement for the detection of QTLs involves appropriate mapping population, marker systems, phenotyping methods and suitable experimental designs (Arrones et al. 2020; Collard et al. 2005)

Mendel’s 3 Laws (Segregation, Independent Assortment, Dominance).In the 1860s, an Austrian monk named Gregor Mendel introduced a new theory of inheritance based on his experimental work with pea plants.Mendel believed that heredity is the result of discrete units of inheritance, and every single unit (or gene) was independent in its actions in an individual’s genome.According to this Mendelian concept, the inheritance of a trait depended on the passingon of these units.For any given trait, an individual inherits one gene from each parent so that the individual has a pairing of two genes. We now understand the alternate forms of these units as ‘alleles’.If the two alleles that form the pair for a trait are identical, then the individual is said to be homozygous and if the two genes are different, then the individual is heterozygous for the trait.The breeding experiments of the monk in the mid-1800s laid the groundwork for the science of genetics.He studied peas plant for 7 years and published his results in 1866 which was ignored until 1900 when three separate botanists, who also were theorizing about heredity in plants, independently cited the work.In appreciation of his work he was considered as the “Father of Genetics”. A new stream of genetics was established after his name as Mendelian genetics which involves the study of heredity of both qualitative (monogenic) and quantitative (polygenic) traits and the influence of environment on their expressions.Mendelian inheritance while is a type of biological inheritance that follows the laws originally proposed by Gregor Mendel in 1865 and 1866 and re-discovered in 1900.
Mendel carried out breeding experiments in his monastery’s garden to test inheritance patterns. He selectively cross-bred common pea plants (Pisum sativum) with selected traits over several generations. After crossing two plants which differed in a single trait (tall stems vs. short stems, round peas vs. wrinkled peas, purple flowers vs. white flowers, etc), Mendel discovered that the next generation, the “F1” (first filial generation), was comprised entirely of individuals exhibiting only one of the traits. However, when this generation was interbred, its offspring, the “F2” (second filial generation), showed a 3:1 ratio- three individuals had the same trait as one parent and one individual had the other parent’s trait.

Mutation
Definition: “Mutation is the change in our DNA base pair sequence due to various environmental factors such as UV light, or mistakes during DNA replication.”
What Are Mutations?
The DNA sequence is specific to each organism. It can sometimes undergo changes in its base-pairs sequence. It is termed as a mutation. A mutation may lead to changes in proteins translated by the DNA. Usually, the cells can recognize any damage caused by mutation and repair it before it becomes permanent.
A mutation is a sudden, heritable modification in an organism’s traits. The term “mutant” refers to a person who exhibits these heritable alterations. Mutations usually produce recessive genes.
