To understand IoT “Internet of Things” it is important to understand internet first. Internet is connecting a device to other device anywhere in the world. When two devices are connected with the Internet, they can send and receive all kinds of information such as text, graphics, voice, and video. The high-speed, fiber-optic cables are used, through which the bulk of the Internet data travels. The Internet has revolutionized the communication world. In today’s scenario the internet is an important part for people around the world. The Internet is a global network of billions of electronic devices. The World Wide Web (www) is most widely used part of the Internet.

The “Internet of Things is a potentially integrated part of the ‘Future Internet’. IoT can be defined as a dynamic global network with self - configuring capabilities based on communication protocols where physical and virtual ‘Things’ interact with each other.

The Internet of Things (IoT) is inter-connecting the networks of smart devices. Smart devices may be embedded with vehicles, buildings, or other electronics object with software, sensors, actuators, and network connectivity. Network connectivity enables smart devices to collect and exchange data. The Internet of Things (IoT), also referred to as the Internet of Everything (IoE) which comprises of the web-enabled devices. IoT has its applications in smart city, smart surveillance, automated transportation, smarter energy management systems, water distribution, urban security and environmental monitoring. Agriculture is another new area of IoT application.

Due to advancement in technology the processing power and storage capacity has been increased, in the recent years. At the same time technology is making the devices pervasive, wearable and mobile. Smart devices are fitted with sensors, actuators which enable devices to sense, compute and act intelligently. They are able to exchange information with environment.

This is a branch of veterinary science that deals with the biology of animal when they are in good health condition, disease status and also deals with the selection of the laboratory animal, important care to be taken and also the usage of these laboratory animals in experiment and also for other research activities.

IMPORTANCE / SCOPE FOR STUDY

Veterinarian with special training/ advanced training in laboratory animal medicine and management are required by medical school, pharmaceutical industries, private and government organization, hospitals, research institutes.

This field of veterinary science has become highly dynamic and it provides good opportunities to satisfy academic professional career.

Usage of these laboratory animals goes back to 2^nd Century. However, the systematic and systemic usage came into existence a century back when research workers started working on polio vaccine. Since then, a debate is going on between scientists of different organizations regarding the usage of laboratory animals.

Large Language Models (LLMs) have emerged as one of the most significant developments in artificial intelligence, transforming the way machines understand, process and generate human language. Their evolution reflects a progression from rule-based systems and statistical language models to neural networks, word embeddings, recurrent architectures and, ultimately, Transformer-based models. This chapter provides a comprehensive overview of this evolution and explains the technological breakthroughs that enabled modern LLMs. It discusses early language modelling approaches, the transition from N-gram models to distributed representations, and the contribution of deep learning and attention mechanisms. The development of influential models such as BERT, GPT, T5, XLNet, PaLM and LLaMA is considered to illustrate increasing capabilities in language understanding and generation. The chapter also examines core LLM capabilities, including question answering, dialogue, summarization, translation and multimodal processing. Finally, it highlights challenges involving hallucination, computational requirements, privacy, bias and responsible deployment, while outlining opportunities for future intelligent and trustworthy AI systems.

The science of Meteorology is defined as the science that deals with physical and chemical processes of the lower atmosphere. The physical and chemical changes in the lower atmosphere produce weather and popularly known as the weather science. The weather science concerns the study of structure, state and behaviour of the lower atmosphere. It is essentially an observational science dealing with different atmospheric variables such as atmospheric pressure, temperature, wind, humidity, density, cloud amount, radiation, precipitation and related variables at a given moment and attempts to predict the behaviour of atmosphere over a period of few hours to few days ahead and disseminate the same in time to the users? community. The statistical approach of weather phenomena deals with the mean state of the physical properties of atmosphere. This branch of science is popularly known as Climatology. The weather science can be categorized into several branches based on method of approach, purpose and function, scale and region. Based on the purpose and function, it can be divided into several branches like Livestock Meteorology, Agro Meteorology, Forest Meteorology, Hydro Meteorology and Bio-Meteorology (Fig 1.1).

Animal husbandry is the most important economic activity in rural areas as livestock plays a vital role in the economy. Over 90 per cent of the milk production comes from small farmers, who are located in rural areas. Growing human population, increasing urbanisation, rising domestic incomes and changing lifestyles in the country have led to increasing demand for dairy products (Anita and John, 2001).

Introduction Market led extension effectively delivers sufficient and high-quality information to farmers so they can make decisions about production and marketing that willmaximize their return on investment without endangering the needs of future generations. Farmers must improve from being producers or sellers in the home market areas to producers cum sellers in a large market to best reap the benefits of their products. This necessitates the transfer of new extension strategies involving a range from local market to export markets, subsistence to commercial agriculture, productivity to profitability, commodity-oriented to farming systemsoriented, mono-cropping to varieties of crops, and so forth. The extension agents’ attention must be diverted from production in some way. Reducing production costs, increasing product value, and enhancing marketability will assist the farming community in receiving high returns for the products.

Introduction
Generally, muscles and offals obtained from animals feeding on grass and various other cultivated crops are regarded as meat. Apart from the meat obtained from the cattle, sheep, goat, pig and poultry, in many countries particularly Denmark, Belgium, Holland and Germany, horse meat is also consumed (hippophasia) as normal meat. Kangaroos are slaughtered for meat in Australia whereas capybara a large semi-aquatic vegetarian rodent, is used in South America as of one of the meat source. Dog meat (fragrant) is relished (Kinophasia) in few cultures such as South Korea, China, Vietnam and few north eastern states of India.
In many parts of the world including Indian subcontinent, buffalo meat (Bubalus bubalis), also known as water buffalo or arna, is quite popular owing to its tenderness, leanness and low cholesterol qualities. It is distributed in many countries around the world such as India (largest population), Pakistan, China, Bangladesh, Indonesia, Philippines, Hungary, Italy and France etc. Bison (Bison bison) from North America is also called buffalo but they are separate species of the order Bovidae. Rabbits are also source of meat having higher growth rate and better feed conversion ratio (2:1). Elands are another meat source which are raised in Africa and Russia for meat purpose.
Meat is quite high in protein content but the presence of saturated fat is perceived negatively due to its association in various cardiovascular diseases, diabetes etc. Efforts are made to produce lean meat having higher content of unsaturated fatty acids and to reduce the ω-6 to ω -3 fatty acids ratio.

Metabolomics is the comprehensive qualitative and quantitative study of metabolites present in biological systems under specific physiological or pathological conditions. This chapter introduces the concept of metabolomics and the metabolome and explains their importance in understanding cellular function and phenotype. It traces the development of metabolomics from classical biochemical analysis through chromatography, mass spectrometry, NMR spectroscopy, and modern high-throughput technologies. The chapter discusses applications in medicine, agriculture, biotechnology, pharmaceuticals, and environmental sciences. It also explains the relationship between metabolomics and systems biology, emphasizing the role of metabolites as functional indicators connecting genotype with phenotype and supporting biomarker discovery and biological systems analysis.

Meteorology is the scientific study of the atmosphere. It focuses on the physical processes and phenomena that occur within the Earth’s atmosphere, including weather and climate. Meteorologists study these processes to understand, explain, and ultimately forecast the Earth’s weather.
Think of the atmosphere as a vast and dynamic fluid that surrounds our planet (Fig. 1.1). Meteorology seeks to understand:
• Composition of the atmosphere: What gases and particles make up the air we breathe?
• Structure of the atmosphere: How is the atmosphere layered (e.g., troposphere, stratosphere)?
• Atmospheric motion: Why does the wind blow? What drives air currents?
• Energy balance: How does the Earth receive and redistribute energy from the sun?
• Formation of weather phenomena: How do clouds, rain, snow, storms, and other weather events develop?

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.

Microscope is an instrument to magnify and enable to see the microorganisms by us.

Microscopes are of two types. Light and Electron microscope.

Basic Principles of light microscope

The light is the primary source on which magnification is performed. The magnification is obtained by a system of optical lenses using light waves. These light microscopes can be further classified into

Molecular biology is a branch of science that deals with understanding the biological activities at the molecular level. Molecular biologists are involved in understanding the concepts behind various intra and intercellular interaction of molecules, contributing to the knowledge about interrelationship of DNA, RNA and protein synthesis, i.e., how genes are transcribed into RNAs and how RNA is translated into protein, the phenomenon which is commonly known as “Central Dogma”stated by Francis Crick in 1956.

“The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred back from protein to either protein or nucleic acid”-Francis Crick.

Mycotoxins are the secondary metabolites produced by moulds, which grow on food and feedstuffs causing pathological or physiological changes to humans and animals. They are toxic to vertebrates in low concentrations. Symptoms depend on the amount of toxin in the feed, the period for which the infested feed is ingested, the nutritional status of the feed and the susceptibility of the animal species. Toxic effects of chronic consumption of mycotoxins in human are carcinogenicity, hepatotoxicity, oestrogenicity, genotoxicity, nephrotoxicity, immunosuppression, reproductive disorders and dermal irritation (Anfossi et al., 2010). The most extensively studied mycotoxins viz., Aflatoxins, ochratoxins, deoxynivalenol (DON, vomitoxin), T-2 toxin, zearalenone, fumoninsins, mycophenolic acid, cyclopiazonic acid and ergot toxins are produced by the moulds Aspergillus, Fusarium, Pennicillium and Claviceps (Iqbal et al., 2015).

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.

India achieved food security through the adoption of high-yielding seed varieties, chemical fertilizers to boost soil nutrition, and pesticides to protect crops. However, this progress came at an environmental cost, including excessive fertilizer use that harmed both human and ecological health.
Natural farming, or prakritik kheti in Hindi, represents a traditional yet evolving approach to agriculture that promotes ecological balance, self-reliance, and sustainability. It is deeply embedded in India’s agricultural legacy, where for centuries, farming was done without synthetic chemicals or mechanization. Today, it is gaining renewed importance as a viable alternative to input-intensive farming, offering solutions to challenges like soil depletion, falling groundwater levels, rising costs, and environmental degradation.
Natural farming operates on the belief that nature is inherently self-sustaining. It avoids the use of chemical fertilizers, pesticides, and GMOs, instead relying on natural, locally sourced inputs to boost soil health and crop yield. This method emphasizes collaboration with nature rather than domination over it. Subhash Palekar’s “Zero Budget Natural Farming” (ZBNF) model, based on low-cost and chemical-free techniques, has been especially appealing to small and marginal farmers.
Soil health is central to natural farming. Techniques like mulching with crop waste, applying jeevamrit (a fermented solution of cow dung, urine, and natural additives), and treating seeds with bijamrit are widely used. These enhance soil microbes and improve its capacity to retain water and nutrients. Natural farming also promotes biodiversity through intercropping, crop rotation, and the use of indigenous seeds.

Theophrastus gave the name “ORCHIDS” to the group of bizarre plants on the basis of the resemblance of paired underground tubers of these plants to masculine anatomy. This resemblance was also responsible for the mistaken belief that the orchids posses aphrodisiac properties and eating of underground tubers might “provoke venus” and they may be get male children. The appreciation of orchid beauty has a very long history in both the Western and Eastern cultures. Much of this is attributed to the diverse form and structure of orchids and the large number of species in the orchid family. Orchidaceae is amongst the most diverse family of the flowering plants consisting of 35,000 species under 880 genera (Kumar and Sheela, 2007, Fay and Chase, 2009). Orchids belong to the highest level of organization and are distinguished by the complicated biology of reproduction with long developmental cycle (Vakhrameeva et al., 1991, Sherif et al., 2012). They are beautiful and exotic perennial herbs grown in both north and south hemispheres. They exhibit an incredible range of diversity in size, shape and colour of flowers. Its flowers have lustrous, translucent petals rich in variegated colors and fragrances. Generally Orchids can grow at different elevations (Kumar and  Sheela, 2007).

Abstract

An intellectual property infringement is the violation of an intellectual property right of the owner. Infringement is established based on the law governing appropriate IPR in the concerned country. Both civil and criminal remedies are available under the concerned law. The present paper introduces the patent infringement as per Indian Patent Act, 1970. It discusses various modes and types of infringements which can take place. It further discusses a procedure to formulate opinion about product infringing a granted patent. In the end some usual defenses against patent infringements have been discussed. Some case studies have also been presented along with the damages awarded for the patent infringement.

Anatomy

The study of gross internal structure of plant organs by the technique of section cutting is called anatomy .The term anatomy was derived from two words ‘ana’ means as under and ‘temnein’ meaning to cut. Anatomy is the branch of science which deals with internal structures and organization of the organism. It is also known as internal morphology. Plant anatomy also describes tissue and tissue systems of the plant body.

Biosecurity refers to the measures aimed at preventing the introduction and/or spread of harmful microorganisms to animals and plants in order to minimize the risk of transmission of infectious disease. Biosecurity is of growing interest as a result of developments at the international level, including globalization of the world economy, technological progress and the rapid increase in communications, transport and trade. Against this background, there is concern that the appropriate level of protection of human, animal and plant life and health is not being maintained as risks increase. Biosecurity is a strategic and integrated approach that encompasses the policy and regulatory frameworks for analyzing and managing relevant risks to human, animal and plant life and health, and associated risks to the environment. 

Several definitions of plant breeding have been put forward. All of these have a core component of the definition that is “the art and science of improving the heredity of plants for the benefit of the humankind” as mentioned by famous plant breeding teacher and a popular plant breeding text book author, J. M. Poehlman. N. I. Vavilov has defined plant breeding as “evolution directed by the will of the man”. The most modern definition of plant breeding by Bernardo (2002) is “plant breeding is the science, art, and business of improving plants for human benefit”. A few more definitions on these lines given by several other famous plant breeders are as follows.

Plant Pathology
The term Plant Pathology is derived from greek words- pathos (suffering) + logos (study) i.e. the study of the suffering plant. Plant Pathology has two phases broadly-
• Science- Understanding of the disease i.e. the theoretical consideration of the suffering plants and how do pathogens invade, how do plants defend themselves, what causes symptoms etc.
• Art- The application of the science to the field problems i.e. Diagnosis and Control.
Plant pathology or phytopathology is the branch of agricultural, botanical or biological science which deals with the cause, etiology, resulting in losses and management methods of plant diseases. 
Plant pathology can also be defined as the study of the nature, cause and prevention of plant diseases. Plant pathology is related to most of the old and new sciences like biology, physics, chemistry, physiology, mathematics, genetics, soil science, biochemistry, biotechnology etc.

Objectives of Plant Pathology
The key objectives of plant pathology include:
1. Understanding Disease Etiology: Identifying the causal organisms or factors responsible for plant diseases.
2. Disease Diagnosis: Developing tools and techniques for early diagnosis of plant diseases.
3. Pathogenesis: Studying how pathogens cause disease in plants and how plants respond to infection.
4. Disease Management: Creating effective and sustainable strategies to control and prevent plant diseases.
Definition and Scope of Plant Pathology
Plant pathology, also known as phytopathology, is the study of plant diseases caused by pathogens (infectious agents) and environmental conditions (non-infectious agents). It encompasses the diagnosis of plant diseases, the mechanisms of disease development, and the development of management strategies. A widely accepted definition of plant pathology is provided by George N. Agrios (2005), who defined it as:
“Plant pathology is the study of the living entities and environmental conditions that cause diseases in plants, the mechanisms by which they induce disease in plants, the interactions between the plant and the pathogen, and the methods of preventing or managing plant diseases.”
Plant pathology integrates principles from microbiology, botany, mycology, bacteriology, virology, and genetics to address plant health issues. It is a critical field for ensuring food security, agricultural sustainability, and the stability of ecosystems

WHAT IS PLANT?

A. Definition - by most definitions, a plant:

is multi-cellular;

is non-motile

has eukaryotic cells

has cell walls comprised of cellulose

is autotrophic; and

exhibits alternation of generations - has a distinctive diploid (sporophyte) and haploid (gametophyte) phase.

History of poultry production

Domestication of birds has a long history, with evidence of their existence and use dating back thousands of years. Here are some key points:

• Chickens: Archaeological evidence suggests domesticated chickens existed in China 8,000 years ago and later spread to Western Europe, possibly via Russia. The cockfighting in India 3,000 years ago indicates their cultural significance. Modern domestic chickens (Gallus domesticus) evolved from the wild red jungle fowl (Gallus gallus), native to India and Southeast Asia.

• Pigeons: The domestic pigeon (Columba livia f. domestica) is considered the world’s oldest domesticated bird.

• Geese: Domestic geese (Anseranserdomesticus in Africa, Europe, and West Asia; Ansercygnoides in East Asia) were domesticated in Egypt over 4,000 years ago and have significance in Roman mythology.

The term project originates from the Latin word projectum derived from the Latin verb proicere, “before an action” which originates from pro-, signifying precedence, something that occurs prior to something else in timing, and icere, “to do”. The term “project” therefore initially signified “before an action. “. A project is a distinct kind of production system that produces a sole unit of product. Like, building a ship or a house, moving a department or a plant, developing a new product or performing a study are examples of such one-of-a-kind products.

In modern business and science, a project is a joint effort, encompassing research or design, that is carefully organized to accomplish a specific goal. The project can also be described as a collection of interconnected tasks to be performed within a defined timeframe and under specific budgetary and other constraints. Projects can be additional defined as temporary instead of enduring social systems or work systems that are formed by teams within or between organizations to achieve specific tasks under time constraints. And all must be expertly managed to deliver the on-time, on budget results, learning, and integration that organizations need. A project in business and science is a provisional endeavor engaged in to produce a distinct item, service, or result. Basically, it is planned to attain a specific goal. The aim of a project is to achieve its goal and subsequently conclude.

Introduction

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.

R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. In a nutshell, R is an open-source software environment for statistical computing that is rapidly becoming the tool of choice for data analysis in the life sciences and elsewhere. It’s developed by a large international community of scientists and programmers and is at the forefront of new developments in statistical computing.

Introduction

R is one of the most popular platforms for data analysis and visualization currently available. It is free, open-source software, with versions for Windows, Mac OS X, and Linux operating systems. R is a language and environment for statistical computing and graphics, similar to the S language originally developed at Bell Labs. It’s an open source solution to data analysis that’s supported by a large and active worldwide research community. But there are many popular statistical and graphing packages available e.g. Microsoft Excel, SAS, IBM SPSS, Stata, and Minitab etc., however R has many interesting features so why it is mostly followed by researchers and academicians. Few of the major features of R are given below:

R software is a programming language used for statistical analysis, graphical representation and reporting, and is currently developed by the R Development Core Team. R software is available freely under the GNU General Public License, and the binary versions are provided for the Windows, Linux and Mac operating systems. To develop R, effort from all over the world is made in a collaborative manner.

What is GNU?

GNU stands for GNU’s Not Unix. It is a Unix like computer operating system, but different from Unix. GNU consists of GNU packages which are program specific and released by GNU project. Free software means that the users of the software have freedom to run and use the software and also can copy, change, improve and distribute the software freely.

Development of R

R software was initially written by Robert Gentleman and Ross Ihaka also known as “R & R” of the statistics department of the University of Auckland, New Zealand. R appeared first in 1993. Since then various contribution to R has been made by a large group of talented individuals by sending code and bug reports. A core group, known as the “R Core Team” modify the R source code archive since 1997. Thus R is a collaborative project with many contributors.

R has become the world-wide language for statistics, predictive analytics, and data visualization. R is not limited to statistics; it provides a wide range of tools for spectroscopy. It offers a wide range of methodologies for spectral data preprocessing, spectral analysis, multivariate analysis of the spectral data, machine leraning models for prediction of properties, and visualization. As an open source project, it’s freely available for a range of platforms, including Windows, Mac OS X, and Linux. An integrated development environment (IDE) for R, R Studio, allows interactive execution of R functions with user interface. RStudio is available in two formats - RStudio Desktop and RStudio Server - both available in free and fee-based (commercial) editions.

Introduction

Regenerative agriculture is both a philosophy and a strategy for land management. It asks us to consider how all aspects of agriculture are connected through a web, which is a network of entities that grow, enhance exchange, and distribute, consumer products and services. Traditionally, supply chains have been organized linearly. It is about farming and ranching in a way that nourishes people as well as the earth, with specific practices differing from grower to grower and from region to region. This style of farming and ranching is also known as “permaculture.” Although there is no definitive rule book, the holistic principles that underpin the dynamic system of regenerative agriculture are designed to address issues of inequity, reestablish the health of soil and ecosystems, and ensure that our land, waters, and climate are in better condition for future generations. It is a novel concept of uplifting the natural world rather than imposing an invasive control, regenerative agriculture intriguing environmental approach to agricultural production that enables the natural systems to renew themselves. Regenerative agriculture refers to farming practices that, in comparison to industrial agriculture, cause significantly less damage to the surrounding environment and the soil. When we give more to nature than what we receive from it, we bring nature closer to us and bring ourselves closer to nature at the same time. Farming that is in harmony with both the surrounding environment and the community fosters a feeling of integrity and togetherness that helps to strengthen the connection between the two. The concept of harmonious farming can be summed up in a few words: It involves engaging in agricultural practices and cropping systems that increase soil fertility return nutrients to the soil, increase soil water retention, remove carbon dioxide (CO2 ) from the atmosphere, and, most importantly, adapt to the ecosystems in which they are grown.

Introduction

The term “Remote Sensing” was coined in 1950s by Ms. Evelyn Pruitt, a geographer with the U.S. Office of Naval Research, and the term is now commonly used to describe as the science and art of identifying, observing, and measuring an object on the earth surface, without having any direct contact. This process involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or materials through which they may be identified and categorized by class/type, substance, and spatial distribution (National Aeronautics and Space Administration—NASA). Remote sensing technology has been widely applied in various applications such as water resources, agriculture, geological studies, forestry, land use, resource exploration, etc.

Elements of Remote Sensing

The remote sensing process involves an interaction between the incident radiation and the targets of interest, exemplified by the use of imaging systems in which the following seven elements are involved; however, remote sensing also involves sensing of emitted energy and using non-imaging sensors

Introduction
Remote sensing is the art and science of recording, measuring, and analyzing information about a phenomenon from a distance. Humans with the aid of their eyes, noses, and ears are constantly seeing, smelling, and hearing things from a distance as they move through an environment. Thus, humans are naturally designed to be remote sensors. In order to study large areas of the Earth’s surface geographers use devices known as remote sensors. These sensors are mounted on platforms such as helicopters, planes, and satellites that make it possible for the sensors to observe the Earth from above.

Definition
Remote sensing can be defined as any process whereby information is gathered about an object, area or phenomenon without being in contact with it. Our eyes are an excellent example of a remote sensing device. We are able to gather information about our surroundings by gauging the amount and nature of the reflectance of visible light energy from some external source (such as the sun or a light bulb) as it reflects off objects in our field of view. Contrast this with a thermometer, which must be in contact with the phenomenon it measures, and thus is not a remote sensing device.

The Renewable energy (also called green energy) is generally defined as energy that comes from resources which are naturally replenished on a human timescale. In other words, Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. The most widely used renewable energy types are solar energy, wind energy,biomass energy, and hydroenergy.
India has made significant progress in the renewable energy sector, with renewable energy accounting for 43.12% of the country’s total installed power generation capacity. Globally, India ranks 4th in overall renewable energy capacity, 4th in wind power with 46.65 GW, and 5th in solar photovoltaic power with 85.47 GW. The country has surpassed 200 GW of non-fossil fuel energy capacity which includes 85.47 GW of solar power, 46.93 GW of large hydropower, 46.66 GW of wind power, 10.95 GW of biopower, 5.00 GW of small hydropower, and 0.60 GW of waste-to-energy capacity.
Presently India has set ambitious renewable energy targets. By 2030, the country aims to achieve 500 GW of non-fossil fuel energy capacity and meet at least 50% of its total energy requirements through renewable sources. These efforts position India as a global leader in the transition towards sustainable and clean energy.
In recent years, India’s renewable energy capacity has grown rapidly. As per the Ministry of New and Renewable Energy (MNRE, 2025), the country’s total installed renewable energy capacity (excluding large hydro) reached 220.10 GW by March 2025. When large hydro and nuclear power are included, the non-fossil fuel capacity has crossed 242.8 GW, representing over 50 percent of India’s total

Agriculture is the science and art of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization. The history of agriculture began thousands of years ago. After gathering wild grains began 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Pigs, sheep and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. This chapter discusses about the agriculture and robotics in agricultural field.

1.1 Introduction to Agriculture

The word agriculture is derived from a Latin word- “agri” means soil, and “culture” means cultivation of the soil. In modern terms, agriculture comprises “the art and science of cultivating the soil, growing crops and rearing livestock.”

Farming is a complete system which includes inputs, processing, and outputs. The inputs are seeds, fertilizers, machinery, which undergoes operations like ploughing, sowing, irrigation, weeding, and harvesting. The final outputs are like crops, dairy and poultry products.

The aggregate of data forming a subject of investigation is known as population. Example, All the crop plants grown in a plot; all the fruit plants in an orchard, etc. The population may be:

1. Finite: No. of observations are definite. e.g., number of farms in a village, no. of house in a locality, no. of trees in an orchard are all finite population.
2. Infinite: Number of observation are indefinite e.g., (a) Number of insects in a region, number of grasses in a field etc. are all infinite population.

The Population may be:

1. hypothetical or theoretical

   Hypothetical population consists of unit that has no physical existence. This population exists only in imagination. For example, Result of tossing coin, throwing die,

2. Existent or real population consists of units that are physically present. This population actually exists. For example, Number of employees in a factory, Number of farms in a village.

Seed

• In broad sense, seed is a material which is used for planting or regeneration purpose. However, scientifically, seed is a fertilized matured ovule together covered with seed coat is called seed or it is a propagating material i.e., part of agriculture, sericulture, silviculture and horticultural plants used for sowing or planting purpose.
• Seed is a mature integumented megasporangium or mature ovule consisting of embryonic plants together with store food material covered by a protective coat.
• Seeds are fertilised, mature ovules, the result of sexual reproduction in plants. Not all plants produce seed (some produce spores or reproduce vegetatively) but most of the higher plants produce seed.
• It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant.
• The formation of the seed completes the process of reproduction in plants (started with the development of flowers and pollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule.

A semiconductor is a material that has an electrical resistivity between that of a conductor and an insulator.

A semiconductor is a substance, usually a solid chemical element or compound that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current. Its conductance varies depending on the current or voltage applied to a control electrode, or on the intensity of irradiation by infrared (IR), visible light, ultraviolet (UV), or X rays.

An external electrical field changes a semiconductor’s resistivity. Devices made from semiconductor materials are the foundation of modern electronics, including radio, computers, telephones, and many other devices. Semiconductor devices include the transistor, solar cells, many kinds of diodes including the light–emitting diode, the silicon controlled rectifier, and digital and analog integrated circuits. Solar photovoltaic panels are large semiconductor devices that directly convert light energy into electrical energy. In a metallic conductor, current is carried by the flow of electrons. In semiconductors, current can be carried either by the flow of electrons or by the flow of positively–charged “holes” in the electron structure of the material.

1.1 Introduction
Sericulture involves raising silkworms to produce silk. It is an agricultural industry that includes growing food plants for silkworms, raising them to produce cocoons, and then processing the cocoons to create yarn for weaving, resulting in value-added benefits.
1.2 Definition of Sericulture
Sericulture (also known as ‘silk production’) involves breeding and caring for silk worms to produce silk on a large scale. This process includes raising the worms on mulberry plants, harvesting and processing their cocoons to extract raw silk fibres, and ultimately creating commercial silk products. The art of silk production is called sericulture that comprises cultivation of mulberry, silkworm rearing and post-cocoon activities leading to production of silk yarn (FAO). While there are many species of silk worms, only a few are commonly used for commercial purposes.
1.3 Silkworm
The silkworm is the larval stage of the domesticated silk moth Bombyx mori, which is in latin also referred to as the “silkworm of the mulberry tree”. Being the main source of silk, it is a significant insect from an economic standpoint. White mulberry leaves are the primary meal of silkworms (monophagous). The generation of domestic silk moths is largely dependent on humans due to millennia of selective breeding. Because wild silk moths
have not undergone selective breeding like their domestic cousins, they are not economically viable to produce silk.

Agriculture is undergoing a major transformation driven by digital technologies, artificial intelligence, and data-based decision-making. This chapter introduces the concept of smart farming and explains the transition from traditional agriculture to precision and digital agriculture. It discusses enabling technologies such as the Internet of Things, remote sensing, cloud computing, machine learning, and data analytics. These technologies facilitate real-time monitoring, precision irrigation, crop surveillance, yield forecasting, and efficient resource management. The chapter also examines the development of cyber-physical agricultural systems and the potential of automation. Challenges including data quality, infrastructure, cost, technology adoption, and the rural digital divide are also highlighted.

Soil fertility -importance

From edaphological point of view soil is a medium for plant growth. It holds and nourishes the plants. Soil fertility refers to the ability of soil to supply plant nutrients. Soil fertility and fertilizers are very much closely related terms; and cannot be neglected one from the other in their function. Soil fertility acts as a ‘SINK’ where in plants can draw nutrients for maximum productivity, where as fertilizer, acts as a ‘SOURCE’ wherein we can apply continuously different nutrients. The importance of soil fertility and nutrient management is being increasingly recognized in all countries recently to meet the demand for food and other agricultural raw materials. Intensive use of fertilizer, intensive cropping and high yielding seeds have no doubt increased the food production and reduced the food shortage but it has also ushered in innumerable problems of soil fertility, soil and water pollution. On the other hand, fast depletion of nutrients due to over exploitation, a wide spread deficiency of N, P, K and S coupled with micronutrients deficiencies specially Zn, B and Mo is taking place. Further deforestation, shifting cultivation, burning of crop residues, trees, bushes, grasses and cow dung, soil erosion, nutrient losses and imbalanced nutrient application, leaching losses etc., have aggravated the depletion of soil fertility status. The productivity of Indian agriculture solely depends on scientific management of soil fertility along with judicious and efficient use of fertilizers integrated with organic sources.

Soil represents a medium or substrate in which numerous microorganisms live and bring about a great variety of processes that are responsible for the continuation of the cycle of life in nature. The numerous living forms which spend their life in the soil, ranging from submicroscopic forms to the lower animal forms. With the growing recognition of the numerous processes carried out by the microorganisms in the soil there gradually emerged a branch of microbiology, which came to known as soil microbiology. It is a branch of soil science concerned with soil-inhabiting microorganisms and their functions and activities.

Since soil microbiology concerns soil microorganisms and their processes it is closely associated with soil biochemistry. Medical bacteriologists are interested in the soil as a medium for the growth and survival of disease-producing organisms. Agricultural chemists are also interested in the soil processes that result from the activities of microorganisms. General bacteriologists, zoologists, botanists are interested in a certain special group of organisms found in the soil. Recently, soil microbiology has expanded to include the study of the role of soil microorganisms in genetic engineering, in the biological control of pests and diseases, the degradation of pollutants, production and destruction of radioactive gases and its transfer. Thus microbial participation in several important processes emphasizes that soil microbiology has become a global science.

“SOIL” the term is derived from Latin word “solum” which means, “floor”. Soil has been a defining component of humanity since the beginning of civilization. It holds the clues of past cultures, it supports the web of life connecting all ecosystems, provides materials to build houses, and provides the base for our food, feed, fiber and even some biofuels.

Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things. It forms at the surface of land and is the “skin of the earth.” Soil is capable of supporting plant life and is vital to life on earth. There are several general roles that soils play:

Spices breeding is the process of developing new and improved varieties of spices through selective breeding, hybridization, and other genetic techniques. The main goals of spices breeding are to enhance desirable traits such as yield, flavour, aroma, disease resistance, and adaptability to different growing conditions. Importance of spice breeding
• Economic value: Spices are economically valuable crops globally. Breeding can lead to higher yields and better quality, improving profitability for farmers.
• Diversity and culinary use: Spices like black pepper, cardamom, turmeric, and chili are used worldwide in various cuisines. Breeding helps to maintain and improve the diversity of these spices.
• Medicinal properties: Many spices have medicinal properties. Breeding can enhance the concentration of beneficial compounds in spices.
Breeding objectives
• Yield improvement: Increasing the quantity of spices produced per plant or per unit area.
• Quality enhancement: Improving the essential oil content, pungency, colour, and other quality traits.
• Disease and pest resistance: Developing varieties that are resistant to common diseases and pests affecting spices.
• Climate adaptation: Creating varieties that can withstand different climatic conditions, such as drought or high humidity.
• Reduced crop duration: Breeding for shorter growth cycles to increase the number of harvests per year.

India is known as the land of spices, while Kerala is often referred to as the spice bowl of the country. Out of the 109 spices acknowledged by the International Organization for Standardization (ISO), India cultivates around 63 spices. The Spices Board of India actively encourages the cultivation and trade of 52 spices. This remarkable diversity in spice cultivation is made possible by India’s varied geographical conditions, encompassing all 15 agroclimatic zones, ranging from tropical and subtropical to temperate regions. These diverse conditions enable the cultivation of almost all kinds of spices.
Definition
Spices are defined as “spices are those plants, the plant products of which are made use as food adjuncts to add aroma and flavour”. Spices are also defined as per the Internal Organization for Standardization (ISO) as “Spices are Vegetable products, or mixtures thereof, free from extraneous matter, used for flavouring, seasoning and imparting aroma to foods”.
Condiments are defined as “condiments are also spices, products of which are used as food adjuncts to add taste only.” Mainly used for seasoning purpose. Herbs are defined as “dried leaves of aromatic plants used for flavouring food”. Both spices and condiments consist of essential oils which enhance the flavour and taste.
