Integrated Pest Management (IPM) is an effective and environmentally friendly step towards pest control based on a combination of common practices. IPM programs use up-to-date and comprehensive information about the life cycle of pests and their interactions with the environment. This information, along with existing pest control methods, is used to control pest damage in the most cost-effective manner and with the least possible risk to people, property and the environment. The IPM methods can be used in agricultural and non agricultural areas, including homes, gardens and workplaces. IPM uses all pest control options, but not limited to the appropriate use of pesticides. In contrast, organic food production shares many of the same concepts as IPM, but limits the use of pesticides to those that come from natural sources rather than synthetic chemicals.

IPM is a set of pest management assessments, choices, and actions rather than a single approach of pest control. Growers using integrated pest management (IPM) that recognize the possibility of insect invasion employ a four-tiered strategy including establishing action levels, keep a look out for and recognize pests, its prevention and control.

IPM establishes an action threshold—a point at which insect populations or environmental circumstances suggest that pest control intervention is necessary—before implementing any pest control measures. It’s not always necessary to take action when one pest is seen. Future decisions about pest treatment must take into account the degree to which pests will pose an economic risk. Set thresholds through systematic, regular, and consistent monitoring. Develop thresholds that are appropriate for your circumstance. Modifying thresholds, management and monitoring techniques if necessary. For the majority of pest monitoring techniques, quantitative thresholds can be created, such as treating when specific circumstances are favorable for the onset of a disease or when the number or percentage of invertebrate pests or damaged plant parts surpasses predetermined limits. A good monitoring procedure involves knowledge of pest and beneficial species likely to be present, awareness of the critical crop development stages, good sampling and recording techniques and an estimate of infestation level.

Cloudy Swelling

Swelling of cells occur with hazy appearance due to a mild injury. The cells take more water due to defect in sodium pump leading to swollen mitochondria which gives granular cytoplasmic appearance. It is the first reaction of cell to the mildest injury. Cloudy swelling is a reversible reaction (Figs. 4.1 & 4. 2).

Etiology

• Can be caused by even mildest injury.

• Any factor causing interference with metabolism of the cell like bacterial toxins, fever, diabetes, circulatory disturbances etc.

Macroscopic features

• Organ becomes enlarged and rounded.

• Weight of organ increases.

• Bulging on cut surfaces.

• Amount of fluid increases in organ.

Microscopic features

• Swelling of cells, edges become rounded.

• Increased size of cells.

• Cytoplasm of the cells becomes hazy/cloudy due to increased granularity.

• Can be seen in liver, kidney and muscles.

The blueberry (Vaccinium spp.) is an evergreen or perennial deciduous shrub that is a member of the Ericaceae family and it is native to North America. It is oblat at maturity and forms dark blue color. Blueberry is also known as “the king of berries,” have real blue fruits, which is very rare in nature (Chu et al., 2018). Tropical, subtropical, and temperate climates make up the majority of the distribution of blueberries. The United States, Chile, Canada, Spain, China, Japan and Morocco are the top producer in the world (Yousuf et al., 2016). Traditionally, 58% of the world fresh blueberries are consumed in North America. The lowbush and highbush varieties combine produced 850,886 tonnes of blueberries in 2020. The United States alone produced around 35% and Peru for 21%. (FAOSTAT 2022).

According to the South Africa Berry Producers’ Association, blueberries were originally brought to South Africa in the 1970s and are currently one of the country’s fastest growing agricultural sectors. There are many places where blueberries are grown, with the Western Cape produced around (60%) followed by Limpopo (15%), North-West (10%), Gauteng (8%), Eastern Cape (4%), Free State (2%) and Mpumalanga (1%) (Steyn et al., 2022). Federick Coville of the United States Department of Agriculture began the first blueberry domestication in 1908. (USDA). High and low bushes are the most widely grown kind of blueberry, however rabbiteyes are only significant in South and North America. High and low bushes hybrids are very common in the upper Midwest of the United States. The main growing countries for north high bush are Australia, Germany, and France.

Introduction Farmer Producer Company (FPC) is a dynamic form of farmer collective that enables strong backward and forward linkage to the member farmer, leading to enhanced socio-economic status amongst the farming community. As of March 31, 2019, there were 7,374 FPCs with a total of 860.18 crore in Paid-Up Capital (PUC). With a budget of 6,865 crore, the Ministry of Agriculture and Farmers' Welfare announced in 2021 central scheme to support 10,000 farmer producer organisations. The Small Farmers Agribusiness Consortium (SFAC), the National Bank of Agriculture and Rural Development (NABARD), and f lagship programmes like the Agriculture Investment Fund (AIF) have all contributed to expanding farmers' access to capital (www.livemint.com).

FPCs are effective tools that give smallholder farmers more influence over the trading markets. This improves agricultural output and raises the revenues of small-scale farmers. To fully realise the potential of FPCs, cluster-based business organisations must acknowledge the inherent difficulties that they face and understand how to avoid common management mistakes.

Branding scenario of successful FPCs

There have been very few Farmer Producer Companies (FPCs) in India that have been running their businesses professionally and have become sustainable organisations over the years with well-established market linkages. Sahyadri Farmer Producer Company (Nashik, Maharashtra), Indian Organic Producer Company (Kerala), Bhangar Vegetable Producer Company (West Bengal), Madhya Pradesh Women’s Poultry Producer Company Pvt. Ltd. (Madhya Pradesh), Nachalur Farmers Producer Company Limited (Tamil Nadu), Maha Gujarat Agri Cotton Producer Company Ltd. (Gujarat), etc. are some of them, to name a few. A lot of sincere efforts have been put into strengthening their marketing linkages, viz. grading, processing, packaging, branding, distribution, etc. All the FPCs have been able to garner a significant market share because of their immaculate branding exercise. Their success has proved the fact that mere branding won’t guarantee large-scale consumer acceptance and it is brand positioning which is the required engine to drag the product towards consumers.

The current study focused to investigate the significance of AgNOR count in diagnosis of canine mammary tumour and its correlation with histopathological evaluation. A total of 53 cases suspected for canine mammary tumour were presented to Veterinary Clinical Complex, DUVASU Mathura from January 2021 to April 2022, out of these 42 cases were screened as neoplastic while 11 were non- neoplastic based on cytological examination. 24 tissue samples were collected out of 42 neoplastic cases during surgical procedure under general anaesthesia for further detailed examination by the approval of Institutional Animal Ethics Committee vide application number IAEC/22/22. AgNOR staining revealed that carcinoma solid had highest number of AgNOR followed by malignant myoepithelioma and fibrosarcoma. AgNOR count gives an assessment of cell kinetics and is directly related to proliferative activity of cells.

A diverse microbial population colonizes the sterile mammalian gastrointestinal tract during and after the birth. This organized and long-lasting process of colonization by microorganisms has developed into flourishing relationships creating diverse environment within the host gut (Mazmanian et. al. 2005). There are various factors that affect the optimum colonization of gut microbiome and their normal functioning on various organ systems of the host body directly or indirectly. The gut microbiome comprises of a complex combination of microbes (Mezouar et. al. 2018). The mammalian gastro-intestinal tract harbors this complex ecosystem in equilibrium with the host immune system. The most magnificent feature of this commensal relationship is that the host not only tolerates but has also evolved to require colonization by commensal microorganisms for its own development and health. There are various factors that affect the optimum colonization of gut microbiome and their normal functioning on various organ systems of the host body directly or indirectly. The process of colonization is a two way interaction between the host and the microorganisms.

The escalating global demand for livestock products, driven by rapid population growth and rising per capita consumption, presents significant challenges for the agricultural sector (Moreau and Jordan, 2005). Traditional livestock production methods are becoming inadequate to meet this demand sustainably. Biotechnology offers novel solutions to enhance productivity, improve animal health, and ensure environmental sustainability (Schmitt and Henderson, 2005). This review aims to explore the role of biotechnology in livestock, focusing on key innovations and their implications for the future of animal agriculture.

1. Genetic Engineering

Genetic engineering has revolutionized the field of animal science by enabling precise modifications of the livestock genome to enhance desirable traits and reduce undesirable ones.

1.1 Transgenic Technology

A mouse was the first successful transgenic animal followed by pigs, sheep, cattle, and rabbits (Shakweer et al., 2023). Transgenic animals are created by inserting foreign genes that encode specific traits, such as growth hormone genes to enhance growth rates or disease resistance genes to reduce susceptibility to infections (Hammer et al., 1985). For instance, transgenic cattle have been engineered to produce milk with modified protein content (Zhang et al., 2019), improving its nutritional profile for human consumption (Brophy et al., 2003). Further, cattle genetically engineered to express human lysozyme in their milk have shown enhanced antimicrobial properties, making the milk safer for consumption (Moreau and Jordan, 2005). These modifications not only boost productivity but also improve the quality of livestock products, making them healthier and more nutritious.

As we delve into the subcellular world, we uncover pivotal insights for advancing our understanding of animal health and disease. Immunoelectron microscopy (IEM) is the same as immunohistochemistry or immunocytochem istry at the light microscopy level. The Power of IEM combines the high-resolution imaging capabilities of electron microscopy with the specificity of immunolabeling. This robust procedure allows us to visualize the precise local ization of proteins and other molecules within cells, providing a detailed cellular architecture and function map. This technique is known as immunogold staining (IGS) or immunogold labelling (De Paul et al., 2012).

Principle of Immunoelectron Microscopy (Iem)

The basic principle of IEM is based on the specific binding of a primary antibody to the target antigen in the sample. A secondary antibody, which is conjugated to colloidal gold particles, is then added. This secondary antibody binds to the primary antibody. The gold particles are electron-dense, meaning they scatter electrons effectively. If viewed under an electron microscope, these particles appear as dark spots, indicating the location of the target antigen. This method demonstrates very specificity and high contrast, making it easier to visualize and study the distribution of proteins at the ultrastructural level (Schwartzbach & Osafune, 2010; Murtey, 2016).

Introduction

Biodynamic farming is a holistic and sustainable approach to agriculture that goes beyond organic practices, incorporating spiritual, ethical, and ecological dimensions into farming and food production. Rooted in the early 20th century, this method is based on the teachings of Rudolf Steiner, an Austrian philosopher, who laid the groundwork for what has become a global movement aimed at creating a harmonious balance between nature and agriculture. Unlike conventional farming, which often relies heavily on chemical inputs and monoculture practices, biodynamic farming emphasizes the interdependence of all elements within a farming system. This includes the soil, plants, animals, and even cosmic forces. The approach seeks to enhance the vitality of the farm as a living organism, fostering a self-sustaining and self-regulating ecosystem.

Central to biodynamic farming is the concept of the farm as a closed-loop system, where all inputs are produced on-site. This includes composting organic waste, rotating crops to maintain soil fertility, and using herbal and mineral preparations to enhance the health and resilience of the farm. These preparations are often made from specific plants, minerals, and animal manure, which are applied according to a biodynamic calendar that aligns farming activities with the lunar and cosmic cycles.

Cooling systems play a vital role in cold chain logistics, serving as essential components that regulate temperature for storage, processing, and transportation. An efficient cooling system ensures that food and other perishable products remain fresh for extended periods, even before they begin their journey. Various cold chain products require specific temperature settings to maintain their quality and integrity until they reach their final destination.
For instance, tropical fruits such as bananas and pineapples must be stored at a consistent temperature between 12°C and 14°C. If the temperature exceeds this range, the fruits may ripen prematurely, compromising their quality. Likewise, food items like milk, vegetables, and other perishable fruits should be cooled within the range of 2°C to 4°C. This temperature effectively eliminates harmful pathogens and prevents bacterial growth, preserving the freshness of the produce.
For businesses dealing with frozen food, seafood, or ice cream, a more advanced cooling system is necessary—one that can maintain temperatures as low as -30°C. Such systems are essential to prevent thawing and spoilage, ensuring that frozen goods remain in optimal condition throughout their transportation and storage.

Beekeeping in India has a long-standing and diverse legacy, deeply embedded in traditional knowledge systems and rural livelihoods. References to honey collection are found in ancient texts like the Rigveda and Charaka Samhita, where honey was valued for its medicinal, spiritual, and culinary uses. Historically, tribal honey hunters collected wild honey from cliffs, tree hollows, and forest hives using time-tested, sustainable methods that honored the natural rhythms of bees. While these practices were rooted in indigenous wisdom, the shift to structured beekeeping—using man-made hives—began during colonial times and gained further momentum after independence.

The establishment of institutions such as the Khadi and Village Industries Commission (KVIC) in the 1950s and the Central Bee Research and Training Institute (CBRTI) in Pune played a pivotal role in promoting scientific beekeeping and offering formal training. In recent years, the focus has transitioned toward more natural and sustainable beekeeping models, especially within organic and natural farming frameworks.

In natural farming practices, the adoption of natural and indigenous hive designs aligns with values of sustainability, simplicity, and care for bee wellbeing. Unlike commercial systems that rely on uniform Langstroth hives for maximum honey production, natural beekeeping focuses on affordable, locally sourced, and non-intrusive hive models that support bees’ instinctive behaviors with minimal disruption.

These hives are constructed to replicate bees’ natural nesting environments, such as hollow trees or crevices in rocks. They offer suitable insulation, darkness, airflow, and internal structure that support the colony’s natural rhythm. Rather than prioritizing honey output, these hives are intended to promote the long-term health and stability of the bees. Typically, natural hives remain in a fixed position, allow bees to build immobile combs, and need fewer inspections, which helps reduce colony stress.

Such indigenous designs uphold the core ideals of natural farming—selfsufficiency, minimal interference, and ecological balance—while also making beekeeping more practical and inclusive for small-scale and resource-limited farmers.

Natural beekeeping emphasizes nurturing bee colonies through a diet that mirrors their natural foraging behavior while avoiding synthetic inputs. Bees instinctively collect nectar and pollen from a diverse range of flowering plants, which supply essential carbohydrates, proteins, vitamins, and minerals for their development, immunity, and productivity. In a thriving environment free from pesticides, bees meet their nutritional needs independently. However, when natural forage becomes scarce—due to seasonal changes, drought, or habitat loss—supplementary feeding may be required to maintain colony strength.

In natural farming, supplements are offered using organic, chemicalfree options such as jaggery-based sugar syrup, diluted honey from surplus or crystallized stores, or herbal infusions made from tulsi, neem, and turmeric to boost bee digestion and immunity. These methods support crucial colony functions like brood development, wax production, and honey storage while reducing stress that could lead to disease outbreaks

Creating and sustaining a healthy aquarium depends on the correct setup and operation of filtration, aeration, and heating systems. These components function collectively to maintain clean water, adequate oxygenation, and consistent temperatures—key elements for the health and comfort of aquatic life.
Filtration systems clear debris, neutralize toxic substances like ammonia and nitrites, and provide a home for beneficial bacteria that fuel the nitrogen cycle. Options include internal filters, canister models, sponge filters, and hang-on-back units, each ideal for different tank capacities and setups.
Aeration equipment—such as air pumps, bubble stones, and diffusers— boosts dissolved oxygen and enhances water movement, which is especially critical in well-stocked or densely planted aquariums and during warmer periods when oxygen tends to deplete. Heaters are essential for tropical tanks, maintaining water temperatures typically between 24–28°C. A stable temperature supports healthy fish metabolism, immune response, and breeding activity. Together, these systems are the core of a functioning aquarium. Choosing the right equipment and maintaining it regularly ensures optimal conditions for both fish and plants.
TYPES OF FILTERS: INTERNAL, EXTERNAL, SPONGE, CANISTER
Aquarium filters come in various types such as internal, external (canister), sponge, and hang-on-back (HOB) filters. Internal filters operate from inside the tank, while external canister filters function outside. Sponge filters work using an air pump that moves water through a foam medium. HOB filters are mounted externally on the tank’s back.

Selecting and adding fish to an aquarium is a crucial process that directly affects the tank’s ecological stability, visual harmony, and long-term success. Effective fishkeeping involves more than just choosing attractive species—it requires a thoughtful understanding of each fish’s behavior, tank needs, dietary preferences, and environmental compatibility.
When choosing fish, consider the aquarium type—whether it’s a community setup, a biotope, or a species-specific tank. Factors such as tank size and water conditions (including pH, temperature, and hardness) should guide your selection. It’s essential to know which species are peaceful (like mollies, tetras, and guppies) and which are known to be aggressive or territorial (such as bettas or cichlids), and
avoid housing incompatible fish together.
Proper stocking density is vital for tank health. Overcrowding can lead to water pollution, increased stress, and disease outbreaks, while too few fish may destabilize the biological balance. The general guideline of “1 inch of fish per gallon” works for small freshwater aquariums, but must be adjusted for fish size, waste production, and swimming habits. New fish should be introduced gradually, particularly in newly cycled tanks, to avoid overloading the filtration system. Quarantining newcomers is also advised to reduce the risk of introducing illnesses.
A well-planned fish selection and stocking strategy promotes a thriving, visually appealing aquarium that is stable, easier to care for, and more enjoyable to watch.
CRITERIA FOR SELECTION: COMPATIBILITY, SIZE, ACTIVITY
When choosing and stocking fish for an aquarium, it’s essential to consider compatibility, adult size, and behavioral traits. Compatibility ensures that fish can coexist peacefully, while size and activity level help prevent overcrowding and stress, contributing to a stable and healthy aquatic environment.

Introduction
Food is a basic human need that is necessary for survival. The three main sources of our food are fishing, farming, and animal husbandry. Modern agricultural practices are unsustainable and employ enormous amounts of pesticides and fertilizers, which pollute the environment. October 16th has been designated as World Food Day.
Global Food Issues
• The rate of food production is not keeping up with the increasing demand.
• There are significant differences in the accessibility of wholesome food. Malnutrition is still a major issue for several tribes, particularly for women and children.
• Our rich soils are being depleted more quickly than they can replenish themselves.
• The conversion of wetlands, meadows, and forests to agricultural usage has resulted in significant ecological issues.
• There is an indication of exhaustion in our upland and marine fish resources.

Climate
This refers to the long-term statistical data of temperature, humidity, wind, precipitation, atmospheric particle count, and many other meteorological parameters in a particular area. However, weather refers to the current state of these same elements over a maximum of two weeks. The statistical long-term representation of the shortterm weather is called climate. A region’s “climate” is its average long-term weather. Temperature and readiness determine the climate. The variations between the average circumstances at two different times can be used to define changes in the climate. The atmosphere, seas, ice sheets (cryosphere), living things (biosphere), and soils, sediments, and rocks (geosphere) all contribute to and are a part of the global climate system.
When the sun falls on moisture droplets in the earth’s atmosphere, a spectrum of light appears in the sky, creating an optical and meteorological phenomenon known as a rainbow.
A wilderness is an area of the planet’s natural ecosystem that has not seen major alterations from human activities.
The atmosphere, a body of gases or air around the earth, shields it from harm and makes life possible. The planet’s atmosphere is primarily made up of nitrogen, with only 21% being oxygen; the remaining little portion is made up of carbon dioxide and other gases. The earth is divided into five separate layers, ranked from lowest to highest:

The Environment (Protection) Act
In 1986, the Environment (Protection) Act was introduced. Concern over the environment’s declining condition grew, leading to the passage of this act to safeguard it. The goal is to plan, organize, and carry out the long-term requirements for environmental safety as well as to oversee and coordinate the development of an effective system for responding to environmental emergencies.
If we want to protect our environment, we must move far more quickly to execute this legislation. Food cycles are disrupted and species are lost when dangerous substancesare present in the atmosphere and aquatic environments in excess.
The Environment Act of 1986 has a Global Context in Addition to Aignificant Constitutional Ramifications.
• This act put into practice the spirit of declaration approved by the United Nations Conference on Human Environment, held in Stockholm in June 1972.
• In the 1970s, environmental protection gained national priority because to the significant growth in damages.
• Food chains are disrupted and species are lost when there are excessive quantities of dangerous substances in the atmosphere and aquatic habitats.
• Goals
• Clearly defining what environmental conservation is.
• Determining the generally acknowledged regions that pose a threat to the life support system.

Integrated Farming Systems (IFS) involve the integration of various agricultural enterprises—such as crops, livestock, fisheries, horticulture, and poultry—within a single farm unit to maximize productivity, ensure sustainability, and diversify income sources. The effectiveness of an IFS largely hinges on selecting the right site and devising a well-thought-out plan, which together create the groundwork for a resilient and efficient farming system. Site selection and planning in IFS focuses on identifying a suitable location and developing a farm layout that allows seamless interaction among different farming components. Key factors to consider include the compatibility of soil and climate, the availability of water and other natural resources, and the optimal use of space and inputs. A carefully chosen site and integrated design enhance synergy between farm components, improve resource efficiency, and increase the overall profitability and sustainability of the system.
TOPOGRAPHY, SOIL, WATER AVAILABILITY, AND CLIMATIC CONDITIONS
In Integrated Fish Farming Systems (IFS) in India, topography plays a crucial role in site selection and planning, impacting the success of the system. Topography affects water management, soil suitability, and overall feasibility of the farm. Local Topography and Site Selection Local topography largely determines which type of pond you will build. The choice is based on the study of the longitudinal profile and cross-secitonal profiles of the valley. Look for Sites:
• Where water drainage will be possible by gravity;
• Where the earthwork will be minimum;
• Where it will be easy to balance the volume of earth to be excavated and that to be filled in.

Integrated fish farming involves the simultaneous cultivation of fish alongside other organisms, such as plants or animals, with the primary goal of achieving maximum yield using minimal resources in a shorter period. One notable form of this practice is Rice–Fish farming, which entails raising fish within the same land area used for rice cultivation. This method yields significantly higher productivity compared to rice cultivation alone.
Traditionally, the practice involved digging several small ditches in the rice fields and adding tree branches or bushes to create artificial habitats for wild fish. Occasionally, Carpio fry were stocked. However, the production levels were quite low—around 50 kg per hectare.
Since the 1990s, Non-Governmental Organizations (NGOs) have actively promoted Rice–Fish farming, enhancing it to include both nursery-stage and tablesize fish production. Additionally, Macrobrachium rosenbergii (giant freshwater prawn) is now cultured to increase profits and diversify outputs. Common species used in modern Rice–Fish systems include Labeo rohita (Rui), Catla catla (Catla), Cirrhina mrigala (Mrigel), Cyprinus carpio (both common and mirror carp), Hypophthalmichthys molitrix (Silver carp), Tilapia species, Thai barb (Puntius gonionotus), and M. rosenbergii. Yields have improved significantly under this system, reaching approximately 200 kg per hectare, much higher than in traditional setups.
PADDY-CUM-FISH CULTURE MODELS (SIMULTANEOUS & ROTATIONAL)
In rice fields that remain waterlogged for 3 to 8 months annually, fish often find their way into the waters naturally. This likely led to the practice of intentional stocking and harvesting of fish in paddy fields. The age-old method of trapping fish and prawns using cloths like gamcha or dhoti in fallow fields is still common in India.

Aquaponics is a method of soilless culture that combines aquaculture (raising fish) and hydroponics (growing plants without soil). It’s a sustainable and efficient system where fish waste provides nutrients for plants, and plants filter the water, creating a closed-loop ecosystem. This integration allows for a self-sustaining food production system with reduced water usage and increased resource efficiency.
CONCEPT OF AQUAPONICS – INTEGRATION OF AQUACULTURE AND HYDROPONICS
Aquaponics is a sustainable farming system that combines aquaculture and hydroponics. Aquaculture involves raising fish or other aquatic animals in tanks, while hydroponics is the practice of growing plants without soil, using nutrientrich water instead. Aquaponics merges these two systems into a symbiotic environment where both fish and plants thrive.

Protected cultivation structures such as greenhouses, polyhouses, and net houses represent significant advancements in agricultural production, offering growers the ability to create an environment that is partially or fully isolated from external weather conditions. These structures are vital tools in modern horticulture and floriculture, especially in areas experiencing unpredictable weather patterns, water scarcity, and heightened pest pressures. The core objective of protected cultivation is to optimize the internal microclimate to meet plants’ physiological needs, ensuring higher yields, improved quality, and year-round cultivation. Achieving these outcomes requires a deep understanding and management of various microclimate factors, such as temperature, relative humidity, light intensity and quality, carbon dioxide (CO?) concentration, and air circulation. Each of these elements plays a crucial role in influencing plant health, photosynthetic efficiency, nutrient uptake, resistance to pests and diseases, and overall productivity.
Effective management of the microclimate begins with controlling temperature, which is arguably the most important factor affecting plant growth. While optimal temperature ranges vary by crop, even small deviations can disrupt essential physiological processes like germination, transpiration, and flowering. To maintain ideal temperatures in protected environments, growers employ a combination of passive and active strategies, such as utilizing roof and side vents for natural ventilation, applying shade nets during periods of intense sunlight, using fogging systems for evaporative cooling, and installing heaters or thermal blankets during colder months. These tools are often automated with sensors and climate controllers, making the system responsive and energy-efficient. In addition to temperature, managing relative humidity (RH) is essential.
Excessive RH can encourage the growth of fungal pathogens, while low RH can lead to water stress and hinder pollination. Maintaining RH between 50% and 70% is ideal for most vegetable and ornamental crops. This can be accomplished

Aquaculture, also known as aquafarming, refers to the controlled cultivation of aquatic organisms—such as fish, crustaceans, mollusks, and aquatic plants— for all or part of their life cycles. As wild fisheries face increasing pressure and limitations, aquaculture has emerged as one of the fastest-growing sectors in global food production, offering a sustainable means to meet the rising demand for highprotein food sources. In India, aquaculture plays a crucial role in enhancing food security, generating rural employment, and contributing to economic growth, particularly in states rich in freshwater and coastal resources like Andhra Pradesh, West Bengal, Odisha, Tamil Nadu, and Kerala. A critical component of aquaculture is the hatchery system. Hatcheries are specialized facilities focused on the artificial breeding, hatching, and rearing of aquatic species during their vulnerable early life stages. They provide a consistent and high-quality supply of seed—such as larvae, fry, or fingerlings—for grow-out in aquaculture systems including ponds, tanks, cages, and raceways. Hatchery operations replicate the natural reproductive environment through scientific interventions such as induced breeding, optimized hatching conditions, and biosecure rearing techniques. Their core objectives include genetic enhancement, disease resistance, improved survival rates, and a dependable seed supply for both commercial and small-scale aquaculture ventures. India has seen significant advancements in hatchery technologies, especially for species such as Indian major carps (rohu, catla, mrigal), freshwater prawns, tilapia, pangasius, and the commercially important shrimp species Penaeus vannamei. Modern hatcheries increasingly rely on sophisticated systems like recirculating aquaculture systems (RAS), flow-through setups, and integrated multi-trophic aquaculture (IMTA) models to enhance efficiency and environmental sustainability. These advancements are supported by institutions such as the National Fisheries Development Board (NFDB), the Marine Products Export Development Authority (MPEDA), and various agricultural universities and research institutes

Broodstock management is a cornerstone of sustainable aquaculture. It involves the careful selection, conditioning, and maintenance of mature fish to ensure the consistent production of high-quality eggs and sperm. The health and reproductive success of broodstock directly influence the quality of fry and fingerlings, which are vital for successful fish farming operations. Effective broodstock management focuses on creating an optimal environment to promote gonadal development, fecundity, and survival. Key environmental factors such as water temperature, dissolved oxygen, pH, and photoperiod are closely regulated. Additionally, species-specific nutrition—particularly diets rich in protein, essential fatty acids, and vitamins—is essential for gamete development and reproductive performance. In captive environments, many fish species face reproductive dysfunction, especially in the final stages of oocyte maturation. Hormonal treatments are commonly used to induce final maturation and spawning. For instance, in salmonids, eggs must be stripped at the precise time of ovulation to prevent overripening, which can occur within hours. Thus, hormonal manipulation is crucial to ensure precise timing and improve spawning outcomes. Species selection for broodstock is based on biological characteristics such as size at maturity, reproductive behavior, feeding habits, and environmental tolerance. Farms may choose to rear their own broodstock from juvenile stages or collect them from wild populations. Those that raise their own become selfsustaining units, independent of external genetic inputs. Broodstock are typically reared in controlled ponds or tanks, with conditions tailored to their specific needs. This includes sex separation when necessary, as different sexes may require distinct environmental or hormonal cues. For example, male and female sturgeons respond to different hormone treatments. Water parameters are continually adjusted to meet species-specific requirements

Induced breeding in freshwater fishes is a technique used to stimulate ripe fish to breed in captivity, typically by injecting them with pituitary hormones or synthetic hormone extracts. This method is crucial for aquaculture as many farmed fish species don’t naturally breed in captivity. Induced breeding is a technique by which the economically important fishes (which generally do not breed in captive condition) are breed through artificial stimulation. Induced breeding is a technique whereby ripe fish breeders are stimulated by pituitary hormone or any other synthetic hormone introduction to breed in captive condition. It is also known as hypophysation.
A BRIEF HISTORY OF INDUCED BREEDING
Induced breeding has revolutionized aquaculture by allowing fish to reproduce under controlled conditions, overcoming their dependence on natural environmental cues for spawning. The technique’s development has seen major contributions from various countries, leading to its global application in fish farming.
• 1930 – Argentina (Houssay): The journey began in Argentina with Houssay’s pioneering use of pituitary extract to induce premature birth in livebearing fish. This milestone introduced the possibility of manipulating fish reproduction artificially.
• 1934 – Brazil: Brazilian scientists built upon this innovation by successfully applying pituitary extract for induced breeding, confirming its broader applicability beyond Argentina.
• Expansion to America and Russia: Researchers such as Merlin and Hubs in the U.S. and Gerebilisky in Russia quickly adopted and refined the technique, promoting its international recognition in aquaculture research.
• 1937 – India (Khan): Khan achieved India’s first success with induced breeding in Cirrhinus mrigala. This event marked the beginning of induced breeding in Indian aquaculture practices.

In Indian aquaculture hatcheries, water quality management is crucial for successful fish seed production. It involves maintaining key parameters like pH, dissolved oxygen, alkalinity, and temperature within the optimal range for the specific fish species being bred. Proper management techniques include monitoring water quality, ensuring adequate water flow, maintaining appropriate feeding practices, implementing aeration and oxygenation systems, and implementing effective waste management.
PARAMETERS
Fish health is closely linked to a delicate equilibrium between the host, potential pathogens, and their aquatic environment. Any disturbance—particularly in water quality—can induce stress in fish, making them more vulnerable to diseases. Therefore, understanding and managing key water quality parameters is essential for optimizing fish growth and survival.
Dissolved Oxygen
The optimal range for dissolved oxygen (DO) in pond water is between 5 mg/ litre and saturation, ensuring healthy fish growth. Aeration is an effective method to improve DO levels. Common aerators include paddle-wheel and aspirator types. In high-aeration ponds, improper placement of aerators along pond edges can generate strong currents that erode the pond bottom. Hence, strategic placement is crucial.
Temperature
Temperature governs fish metabolism by affecting molecular properties and biochemical reaction rates. Ideal temperature ranges vary: 14–18°C for coldwater species and 24–30°C for warmwater species. In controlled environments like hatcheries, water temperature can be regulated. In large ponds, aerator operation during calm, warm afternoons helps disrupt thermal stratification. Tree planting for shade may help regulate temperature but can reduce sunlight penetration, thus lowering pond productivity.

Health and disease management is a crucial component of hatchery operations in aquaculture. Hatcheries, which rear aquatic organisms like fish, crustaceans, and mollusks during their early life stages, are particularly vulnerable to disease outbreaks due to high stocking densities, variable water quality, and the fragile nature of eggs, larvae, and fry. These outbreaks can result in significant mortality, reduced seed quality, and substantial economic losses.
To prevent such outcomes, a comprehensive health management strategy is essential. This includes maintaining optimal water quality, implementing proper feeding practices, and minimizing stress on the organisms. Regular monitoring and early diagnosis help in identifying diseases promptly, allowing for targeted and effective treatments.
Robust biosecurity protocols are also vital. These measures aim to prevent the introduction and spread of pathogens through controlled access, disinfection procedures, and quarantine practices. Together, these steps help create a stable, disease-free environment that supports the healthy growth and survival of hatchery-reared aquatic species.

INTRODUCTION TO ROUTINE MAINTENANCE PROCEDURES FOR AGRICULTURAL DRONES
Regular maintenance of agricultural drones is crucial for their best performance and durability, as these sophisticated devices are integral to contemporary agriculture. Agricultural drones endure severe climatic conditions, such as dust, wetness, and fluctuating temperatures, which might impact their performance. Routine maintenance activities, including cleaning, inspecting, calibrating sensors, and assessing component wear, mitigate expensive downtime and guarantee that drones consistently provide accurate data for applications such as crop monitoring, irrigation management, and pest control. By following a regular maintenance schedule, farmers may optimize the dependability and effectiveness of their drone technology, so improving production and reducing the likelihood of malfunctions during essential activities.
UAV systems (drones) necessitate routine maintenance inspections to verify optimal functionality. They are susceptible to deterioration from prolonged usage, particularly when utilized within a bigger fleet.
This checklist may be utilized as frequently as necessary for routine maintenance inspections; however, it is more efficacious to conduct maintenance on a per-flight basis rather than at fixed intervals. Scheduling will more precisely indicate the likelihood of the drone requiring maintenance.
You likely already possess established procedures for determining when and how to conduct maintenance. Verify all items on this list to confirm their operational status and facilitate any required repairs or replacements prior to the next flight.

INTRODUCTION TO SAFETY PROTOCOLS FOR DRONE OPERATIONS
Drones in agriculture have transformed how farmers oversee and cultivate crops, enhance efficiency, and optimize resources. Nonetheless, like any sophisticated technology, the utilization of drones in agricultural contexts necessitates compliance with stringent safety measures to safeguard the operator, the surrounding environment, and the equipment. The size, power, and complexity of agricultural drones entail inherent operational hazards, including possible accidents, collisions, and interference with other equipment or humans. Implementing safety measures not only prevents accidents but also guarantees the accuracy and reliability of acquired data, hence optimizing the advantages of drone technology in agriculture. By complying with safety regulations, such as conducting thorough pre-flight inspections, establishing secure flight areas, and implementing emergency response protocols, farmers can mitigate risks while maximizing the benefits of drones in agricultural management.
Implementing safety guidelines for drone operations in agricultural environments is crucial to safeguard both operators and the ecosystem while optimizing technological efficacy. Drones serve as potent instruments for activities such crop monitoring, spraying, and soil health evaluation; nevertheless, inadequate management or noncompliance with safety protocols may result in accidents, equipment damage, and data integrity issues. The following are essential safety protocols to adhere to when operating drones in agricultural environments:

INTRODUCTION
A Primary Processing Centre (PPC) is a facility that offers essential infrastructure for the initial processing of agricultural produce, including grading, sorting, packaging, and storage. These centers are strategically located near production zones within raw material catchment areas and are supported by Collection Centers (CCs) in nearby villages.
The establishment and efficient management of a Primary Processing Centre (PPC) play a crucial role in enhancing the value of raw agricultural products, improving their marketability, and minimizing post-harvest losses. A welloperated PPC integrates modern processing technologies, optimized resource utilization, and streamlined logistics to ensure high-quality output and long-term sustainability. Advanced processing methods such as drying, milling, juicing, and canning help maintain product quality and nutritional integrity while reducing waste. Additionally, a robust management framework is essential for supervising operations, implementing quality control measures, and maintaining an efficient supply chain that connects local farmers to the processing facility. The effectiveness of a PPC extends beyond technical efficiency, as it also fosters community empowerment through job creation, skill enhancement, and active participation, thereby contributing to both economic development and sustainable agricultural practices. By harmonizing these elements, a PPC serves as a critical hub for agricultural progress, granting farmers improved market access, decreasing reliance on unprocessed exports, and generating value-added products that align with consumer demand.
The manufacturing and management of a Primary Processing Centre (PPC) play a crucial role in transforming raw agricultural produce into value-added products that enhance marketability, reduce post-harvest losses, and improve farmers’ income. A well-established PPC serves as a key

Beekeeping in India has a long-standing and diverse legacy, deeply embedded in traditional knowledge systems and rural livelihoods. References to honey collection are found in ancient texts like the Rigveda and Charaka Samhita, where honey was valued for its medicinal, spiritual, and culinary uses. Historically, tribal honey hunters collected wild honey from cliffs, tree hollows, and forest hives using time-tested, sustainable methods that honored the natural rhythms of bees. While these practices were rooted in indigenous wisdom, the shift to structured beekeeping—using man-made hives—began during colonial times and gained further momentum after independence. The establishment of institutions such as the Khadi and Village Industries Commission (KVIC) in the 1950s and the Central Bee Research and Training Institute (CBRTI) in Pune played a pivotal role in promoting scientific beekeeping and offering formal training. In recent years, the focus has transitioned toward more natural and sustainable beekeeping models, especially within organic and natural farming frameworks. India’s ecological diversity supports a wide range of bee species, including the native Apis cerana indica, Apis dorsata, and Apis florea, along with the introduced Apis mellifera. This variety allows region-specific approaches to beekeeping based on climate, flora, and agricultural needs. Despite India’s potential to support over 200 million bee colonies, fewer than 5 million are currently managed, highlighting the vast scope for expansion. With growing domestic and global demand for raw honey, beeswax, and pollination services, interest in apiculture is steadily increasing. Government programs under the “Sweet Revolution,” support for Farmer Producer Organizations (FPOs), and an emphasis on organic certification have opened up new opportunities—especially for youth and women in rural areas. Ultimately, beekeeping in India embodies a harmonious blend of heritage, biodiversity, and

In natural farming practices, the adoption of natural and indigenous hive designs aligns with values of sustainability, simplicity, and care for bee wellbeing. Unlike commercial systems that rely on uniform Langstroth hives for maximum honey production, natural beekeeping focuses on affordable, locally sourced, and non-intrusive hive models that support bees’ instinctive behaviors with minimal disruption. These hives are constructed to replicate bees’ natural nesting environments, such as hollow trees or crevices in rocks. They offer suitable insulation, darkness, airflow, and internal structure that support the colony’s natural rhythm. Rather than prioritizing honey output, these hives are intended to promote the long-term health and stability of the bees. Typically, natural hives remain in a fixed position, allow bees to build immobile combs, and need fewer inspections, which helps reduce colony stress. Such indigenous designs uphold the core ideals of natural farming—selfsufficiency, minimal interference, and ecological balance—while also making beekeeping more practical and inclusive for small-scale and resource-limited farmers.
LOG HIVES, CLAY HIVES, BAMBOO HIVES
Log, clay, and bamboo hives are classic examples of indigenous beekeeping practices that reflect early, resource-efficient methods using materials found in the local environment. These hive designs are built to replicate natural nesting habitats, supporting sustainable beekeeping aligned with natural farming principles. Their simplicity, affordability, and low input requirements make them particularly suitable for tribal communities and small-scale farmers practicing chemical-free, traditional apiculture.

Natural beekeeping emphasizes nurturing bee colonies through a diet that mirrors their natural foraging behavior while avoiding synthetic inputs. Bees instinctively collect nectar and pollen from a diverse range of flowering plants, which supply essential carbohydrates, proteins, vitamins, and minerals for their development, immunity, and productivity. In a thriving environment free from pesticides, bees meet their nutritional needs independently. However, when natural forage becomes scarce—due to seasonal changes, drought, or habitat loss—supplementary feeding may be required to maintain colony strength. In natural farming, supplements are offered using organic, chemicalfree options such as jaggery-based sugar syrup, diluted honey from surplus or crystallized stores, or herbal infusions made from tulsi, neem, and turmeric to boost bee digestion and immunity. These methods support crucial colony functions like brood development, wax production, and honey storage while reducing stress that could lead to disease outbreaks. Care must be taken not to overfeed or use inappropriate substances like refined sugar or commercial syrups with additives, as these can disrupt bees’ digestive systems and lower immunity. All supplements should be natural, safe, and easily assimilated by bees. Health management in natural beekeeping avoids synthetic antibiotics, pesticides, and miticides, which can damage colonies, taint hive products, and foster resistance. Instead, it relies on proactive strategies such as clean hive conditions, good ventilation, regular inspections for signs of illness, and surrounding the apiary with medicinal plants. Natural remedies like neem or garlic water sprays deter pests, while substances like turmeric or ash address fungal problems. Propolis-rich hive materials also enhance the colony’s natural defenses. Sustainable beekeeping depends on healthy, well-nourished, and genetically resilient colonies that thrive with minimal interference. The beekeeper’s role is

A machine learning model is a program that can find patterns or make decisions from a previously unseen dataset. For example, in natural language processing, machine learning models can parse and correctly recognize the intent behind previously unheard sentences or combinations of words. In image recognition, a machine learning model can be taught to recognize objects - such as cars or dogs. A machine learning model can perform such tasks by having it ‘trained’ with a large dataset. During training, the machine learning algorithm is optimized to find certain patterns or outputs from the dataset, depending on the task. The output of this process - often a computer program with specific rules and data structures - is called a machine learning model. Machine Learning Model is a computational program that learns patterns from data and makes decisions or predictions on new, unseen data. It is created by training a machine learning algorithm on a

Financial modeling using Python has emerged as a highly effective approach for modern finance, combining the flexibility of programming with the analytical rigor required for accurate forecasting and decision-making. Python is particularly valuable because it can handle large datasets, automate repetitive tasks, and integrate advanced statistical and machine learning techniques into financial models, surpassing the limitations of traditional spreadsheet-based approaches. Its extensive libraries, such as pandas, NumPy, scikit-learn, and matplotlib, make it an ideal tool for building robust and dynamic financial models. The foundation of financial modeling in Python begins with data acquisition and preprocessing. Financial data is often sourced from databases, APIs, or CSV files, and Python provides efficient tools to import and clean this information. The pandas library allows analysts to create dataframes, which are flexible structures for organizing, filtering, and transforming data. Preprocessing tasks, such as handling missing values, normalizing variables, and converting date formats, ensure that datasets are ready for accurate modeling. This step is critical, as errors or inconsistencies in the data can lead to incorrect forecasts and flawed financial decisions. Once the data is prepared, Python enables comprehensive exploratory data

Quality control in fish feed manufacturing plays a vital role in ensuring the safety, nutritional value, and uniformity of the final product. It involves a structured set of procedures carried out throughout the entire production cycle— from sourcing raw materials to packaging the finished feed—to confirm that the product adheres to standards that support fish health, growth, and environmental stewardship. At the initial stage, raw materials are tested for factors such as moisture, protein, lipid content, fiber, ash, and the absence of harmful elements like aflatoxins, pesticides, or heavy metals. Leading feed manufacturers enforce strict supplier verification and sampling routines to maintain ingredient quality and authenticity. During production, critical parameters are routinely checked, including grind size, mixing consistency, and temperature and moisture levels during conditioning. The physical integrity of pellets is also evaluated during extrusion or pelleting. Specific performance indicators—like water stability, floatability for floating feeds, and feed conversion ratios (FCR)—are assessed to determine feed effectiveness. Post-production checks include examining the pellet’s appearance (size, shape, and color), along with chemical assessments

Probability analysis measures the likelihood of uncertain climatic and agricultural events. It is particularly useful for assessing rainfall occurrence, drought, floods, heatwaves, cold events and other risks that cannot be predicted with complete certainty. This chapter introduces classical, empirical, subjective and conditional probability, probability distributions, return periods and recurrence analysis. It explains how historical climatic records can estimate the likelihood and severity of future events. These methods assist in crop selection, sowing decisions, irrigation planning, infrastructure design and weather-risk management. By converting uncertainty into measurable probabilities, the chapter provides a scientific basis for climate-informed agricultural planning, disaster preparedness and development of resilient farming systems.

Laparoscope

The term laparoscope derived from Greek word “Laparo” meaning “flank,” which is the side of the body between the ribs and hips (abdomen) and “scope” means to look at or examine. Laparoscope can be defined as an instrument through which structures within the abdomen and pelvis can be seen or a fiber optic device that consists of a flexible tube. Fiber optic scope is used to directly visualize the internal anatomy of a hollow organ. Laparoscope is used in laparoscopy and laparoscopic surgery. It has lenses like a telescope to magnify body structures, a powerful light to illuminate them and a miniature video camera. The camera sends images of the inside of the body to a TV monitor in the operating room. Specialized surgical instruments can be inserted through the laparoscope.

Among the various modern surgical methods, laparoscopy is now held as one of the most potent and promising aids for both diagnostic (laparoscopy) and therapeutic (laparoscopic surgery) use. Laparoscopy is an endoscopic procedure that bridges the gap between clinical evaluation and surgical exploration. The laparoscopic surgical techniques in both and human and veterinary medicine have grown tremendously. Laparoscopy requires a minor surgical intervention and it provides the only available practical means of making repeated direct observation of abdominal viscera. The advantage of surgical laparoscopy over the conventional open surgical laparotomy include faster patient recovery because of smaller surgical sites, decreased hospitalization, improved cosmetic, improved visualization of abdominal organs, lower postoperative morbidity with lower infection rates, and less postoperative pain and stress. Surgeons are commonly looking for more progressive and stressful surgical methods of sterilization in dogs, particularly in canine birth control programs in urban industrial areas. Demographically dense urban and industrial areas require effective animal birth control programs that can overcome the problems of hospitalization, postoperative complications and reduction in the overall cost of operation. In a large scale animal birth control program, the conventional methods of sterilization require a long period between capture of dogs and their release, due to the time taken for the surgical wounds to heal. In this aspect, keyhole surgery (laparoscopic surgery) can revolutionize the entire program, as it needs only a very small surgical wound, which usually needs no postoperative care or regular dressings.

Abstract

In recent years the quest for improving the quality of life has ventured into many aspects of utilizing plants for the aesthetic sense. One such is an increased utilization of flowers /flowering plants for beautification of homes, offices, gardens etc. The increased interest in use of cut flowers has brought challenge of bringing in varieties of natural flowers from different sources. India’s rich biodiversity also contributes addition of lot of new species to the cut flower industry. Banana and Plantains have been revered only for their utility as dessert fruit or staple food. But aesthetic dimension has never been much explored. Musa comprises more than 50 species and sub species traversed across the tropical and sub-tropical regions of the world. Musa Ornata is one such plant, native to north eastern regions of India, belongs to the family Musaceae and section Rhodochlamys. It draws its attention by virtue of its bright inflorescence and its long lasting nature. It is a medium statured plant, hence suitable for gardens also. It is a fertile wild species, multiplies mainly through suckers and through seeds to some extent.

Abstract

Agricultural practices prior to the eighteenth century were completely dependent on crop landraces and their mixtures. The knowledge of plant genetics and its application to crop improvement programmes led to increase the production potential of agriculture. Contrary to this, the wonders of crop improvement have resulted in the erosion of genetic diversity of many crops in farmers’ fields, including wheat, due to the replacement of landraces and farmers’ old cultivars with modern high-yielding cultivars.

Wheat is cultivated over an area of 216.6 million hectare globally and the production is 674.9 million tons. The seven largest producers of wheat are China, India, the Russian Federation, the USA, France, Turkey and Canada. During 2012-13, India produced 92.46 million tons of wheat from 29.65m ha area with productivity of 31.19q/ha (4th Advance Estimates, Directorate of Economics and Statistics, Government of India). Three wheat species namely, T. aestivum L., T. durumDesf. and T. dicoccumSchubl are grown in India as commercial crops covering 95, 4 and 1 percent area, respectively. The cultivation of T. dicoccumis confined largely to the regions of Karnataka and Maharashtra.

With regard to post harvest operations, cent percent of respondents graded the produce manually and jute bags used to store the produce, whereas, 71.67% of the respondents sold later when price was suitable in regulated market (90.00%) through commission agents (77.50%) and got price information by personnel visit/phone call to regulated market (81.67%) and others who visited the market (68.33%). But no farmer certified the produce and sold at premium price. With regards to personal characteristics, majority of respondents (31.62 %) were illiterate, 59.17 per cent were had joint family, 61.17 per cent were having low farming experience, 60.83 per cent of respondents were big land holders and 69.17 per cent of respondents possessed medium level of scientific orientation.

Abstract

Many people’s food and livelihood security depend on the sustained management of various biological resources that are important for food and agriculture. Agro biodiversity is the result of the interaction between the environment, genetic resources and management systems and practices used by culturally diverse peoples. The management of agro biodiversity by the indigenous communities is for a variety of reasons. The land use types, land use stages, aspect, soil fertility, availability of water and quality seed of crops etc. are essential variables which an indigenous farmer considers while cultivating a diversity of traditional landraces in the farm for food security. India is the largest producer of many kinds of millets, which are often referred as coarse cereals. However, realizing the nutrient richness of these grains they are now considered as nutria-cereals. Small millets, as a group includes several grain crops namely finger millet (ragi), proso millet, barnyard millet, italian millet, kodo millet and little millet. In the four decades since 1961, the area under millets declined by nearly 50% from about 18 million hectares to about 9 million hectares. During this time, production of millets declined from about 8.8 million tons to about 7.2 million tons; a decline of 18%. Tremendous decrease in area and production is directly or indirectly resulted in the loss of agro biodiversity of these crops as these crops are grown on marginal or rainfed areas without any fertilizers. Therefore, more emphasis should be given for maintaining bio diversity of these highly rich crops by increasing area under these minor millets and developing proper agro techniques for increasing its productivity.
