Introduction

A geographic information system or geographical information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. The acronym GIS is sometimes used for geographic information science (GIScience) to refer to the academic discipline that studies geographic information systems and is a large domain within the broader academic discipline of geoinformatics. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries. In a general sense, the term describes any information system that integrates stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. Geographic information science is the science underlying geographic concepts, applications, and systems.

GIS is a broad term that can refer to a number of different technologies, processes, and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization. GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth-based spatial–temporal location and extent references should, ideally, be relatable to one another and ultimately to a “real” physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry.

The term ‘Horticulture’ is derived from two Latin words, Hortus meaning Garden and Cultura meaning Cultivation. In ancient days the gardens had protected enclosures with high walls or similar structures surrounding the houses. The enclosed places were used to grow fruits, vegetables, flowers and ornamental plants. Horticulture differs from agriculture and forestry in specializing the cultivation of garden crops. The garden crops include fruits, vegetables, flowers, ornamental trees, spices, plantations, medicinal and aromatic plants. Horticultural crops do not give food grains. The products of horticultural crops such as fruits and vegetables are highly perishable so that they are utilized in the fresh state. In general horticultural crops need more intensive cultivation (i.e. need more work) than the agricultural crops.

Special Features of Horticulture

As horticultural crops generally need intensive cultivation, they require a large input, capital, labour and technology per unit area of land.

Many cultural operations are specific to horticultural crops. The cultural operations such as propagation, fertilization, training, pruning, harvesting and marketing are skilled operations and these are specific to horticultural crops.

Mostly the horticultural products are utilized in the fresh state and are highly perishable.

Most of the horticultural crops are the rich sources of vitamins and minerals.

Gratification or aesthetic sense is an exclusive phenomenon for horticultural science.

Introduction

Impact studies isolate the effect of an intervention by assuring that there is clean comparison between a treatment group that received the intervention and a comparison group that is just the same except that it did not get the intervention.

Impact studies test whether one thing causes another. Just knowing scores have gone up following an intervention doesn’t mean improvement is attributable to that intervention.

The data are generated from an impact study used to identify best practices, to replicate successful programs or policies, and to avoid mistakes that might have negative implications for future projects.

Intellectual property (IP) refers to the creations of the human mind that can be protected and have commercial value. These creations, or “intellect,” can take various forms, such as inventions, artistic works, and designs. Converting intellectual property into a useful product or process requires resources like time, effort, skill, and financial investment. Intellectual property rights (IPR) are legal rights granted to innovators and creators, giving them exclusive control over the use and monetization of their inventions and creations. IPRs are territorial and allow creators to sell, license, transfer, or otherwise dispose of their rights, similar to physical property.

IPRs are considered crucial for promoting economic growth and development, as they encourage innovation, investment, and entrepreneurship. Without IPRs, inventions and creative works could be easily copied or stolen, resulting in reduced incentives for innovation and decreased economic value. Lack of IPR can also lead to an increase in infringements and economic losses. In recent years, India has been increasing its awareness of IPR and has seen a rise in registrations of indigenous technology, patents, trade secrets, and copyrights among others.

The Internet of things connects the devices over Internet. The devices can communicate with each other and can be monitored and controlled remotely. The IoT is a system with interrelated computing devices, digital and mechanical machines, objects, animals or people each with an unique identifiers (UIDs ). It has the ability to transfer data over a network without human intervention. The Internet of Things is simply a network with Internet connecting the objects to collect and exchange the data. This chapter covers the basics of Internet of Things and its components.

2.1 Characteristics of IoT

Internet of Things can be used to design products for businesses. The added value to the businesses over IoT is created by the information which is collected by connected devices. The process has five phases of lifecycle, first phase is ‘create phase’, where sensors collects the data from environment. This data can generate the information. Second is ‘communicate phase’ where data generated in first phase is communicated to the required destination. Third is ‘aggregate phase’ where collected data over network is aggregated by device itself. Fourth is ‘analyse phase’ where aggregated data is used to generate patterns and use it to control and optimize the process. Fifth is ‘act phase’ where actions are taken on the basis of information extracted from the aggregated data.

The characteristics of IoT may vary from one domain to other. Few characteristics are listed as follows-

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.

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.

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).

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.

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.

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.

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.

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.

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:

Q.1 Statistics in singular is used to denote a subject (branch) of science.

Q.2 Statistics in plular is used to denote data or methods.

Q.3 The data first time collected is known as primary data.

Q.4 Primary data is collected from published report.

Q.5 Editing of data is not necessary.

Q.6 Consistency must be maintained in data.

Q.7 Baised and unbiased errors are known as statistical error.

Q.8 Arrangement of data in different, rows & columns is known as classification.

The word ‘statistics’ has been derived from the Latin Word ‘Status’ which means ‘Political State’. The word statistics has been coined by Gottfried Aschenwall, a German Political Scientist. Ronald Aylmer Fisher is regarded as father of modern statistics. The word statistics has meaning both in plural and singular sense. In plural sense, it means quantitative/qualitative figures. For example, the area under food grains in different states of India, the production of guava in different states of India, germination percentage of seeds, etc.. In singular sense, it means as a subject i.e., method of dealing with the quantitative/qualitative information.

Statistics is defined as scientific method which deals with collection, organization presentation, analysis and interpretation of data. It is included under both science and arts. Statistics is used as a tool to obtain knowledge on other subjects of science.

1.2 Introduction

Statistics is a powerful and essential field of study with substantial importance in various aspects of life, science, business, and society. Its significance lies in its ability to provide a systematic framework for collecting, analyzing, interpreting, and presenting data. Statistics is a universal language of data that empowers individuals, organizations, and societies to make informed decisions, solve problems, and gain deeper insights into the world around us.

Introduction

Strategy is to achieve a particular goal or set of goals through plan of action. Importance of strategy: Strategy helps organizations to focus on their longterm goals and objectives, and to allocate their resources in the most effectiveway to achieve those goals.

 Types of strategy: There are several types of strategies, including corporatestrategy, business-level strategy, functional-level strategy, and operationalstrategy.

 The strategy development process: The strategy development processtypically involves several steps, including analyzing the external and internalenvironment, setting objectives, formulating a strategy, implementing thestrategy, and evaluating the results.

 Organizational strategy tools and techniques: Numerous tools andtechniques exist for organizations to foster and execute their strategies. These encompass SWOT analysis, PESTLE analysis, Porter's Five Forces analysis, and the Balanced Scorecard.

The food productivity increased manifolds due to high-input modern agriculture with the adoption of new technologies like high yielding varieties, farm mechanisation, increased use of fertiliser and pesticide, specialised farming practices, water resource development and improved irrigation practices, etc. The Green Revolution started in the early 1960s has led to the attainment of self-sufficiency in food grain production.

This book is designed to introduce to the students some of the most widely used experimental procedures in biotechnology, including DNA/RNA isolation, manipulation, cloning, protein purification and characterization. The students will also get familiarized with some of the equipments frequently used in biochemistry and molecular biology.

The biotechnology laboratory course is an exploration of procedures. Hence, in order to get full benefit from the course, the students need to read the manual, which is self explanatory. The more effort they put into the course work, the more they will learn. Before the start of actual lab works, one needs to spend some time reading the Laboratory Manual. This reading will provide background information and an outline of the procedures to be performed.

The biotechnology laboratory is conducted as a “directed” research project. This means that although the general procedures are well established, the overall goal of each experiment is the acquisition of new information. Because of the nature of scientific research, predicting the outcome of experiments that have not previously been performed is difficult. It may therefore be necessary to design new experiments based on the results of previous ones, or to repeat experiments that yielded uninterruptable or ambiguous results.

1.1 Importance

Perfumes, essential oils and aroma are some of the products which indicate religious values, living standards, personality development for personal use and adornment from years back. The Vedic literatures also indicate the presence of perfumes and aromatics and were used for religious purposes as well as medicinal purposes. The word perfume has been used today to describe scented mixtures and is derived from the Latin word, “per fumum”, meaning through smoke. Perfumery has been one of the Indian arts and was a famous centre for perfume and perfume products. The essential oil means a class of volatile odoriferous oils, obtained from raw material of botanical source that impart the plant odour and other characteristic properties derived through distillation (usually with water or steam) or expression and obtained in the form of an oily liquid. The oils extracted through expression are some time called “Expression oils”. The aromatic substances being used from the Vedic period are defined as those plants which possess odoriferous steam volatile constituent’s (essential oil) in them.

Brazil, China, Egypt, India, Indonesia and USA are the major producers of aromatic materials. China is becoming increasingly important as a primary source and a very large quantity of aromatics and flowers as raw material is available. European Union and Switzerland are the main world markets for aromatics and also has established as a largest consumer of essential oils. The world’s largest importer of aromatic materials is the USA followed by Japan. The latter accounts for about 10% of world demand especially for lemon, clove, orange, peppermint and cedar wood oil.

India exports essential oils of lemongrass, mint, sandalwood, palmarosa, cardamom, ginger and eucalyptus in adequate quantity under AGMARK certification. But, for a better export quality there is a need to study the customer requirements, quality assurance and standards to keep pace with International market, Total Quality Management (TQM) through adulteration detection and modern analysis techniques with economic marketing channels.

India possesses a number of resources as plant parts, ample land and varied climatic conditions with low production costs but the essential oil producers need to study the customer needs for a regular supply of best quality products at a competitive rates. Today, second important factor for successful competition is the quality assurance. The consumers, these days, are very much aware about the quality and safety of using perfumes, essential oils and other pharmaceutical products. The third most important point is the packaging which attracts the consumers most of the times. Proper packaging along with an attractive label is always a plus point for the marketing of any product. Hazard Analysis Critical Control Point (HACCP) and Good Manfacturing Practices (GMP’s) are the quality assurance systems which continuously controls and regulate the quality production of commodities, needs strict enforcement. ISO 9000, TQM and ISO 14000 series are the some of quality management organizations, working for the development of quality standards.

Ultrasonography is the process of obtaining images of an area, organ or tissue with the help of ultrasound beam that can be displayed on a screen. Such images can be recorded on videocassettes or printed on a thermal paper. Ultrasonography in veterinary practice is a revolutionary step for diagnosis of various ailments and to assess normal physiological functions of the body organs of domestic animals. Ultrasonography is considered a wonderful tool particularly for the study of reproductive functions viz. follicular dynamics, pregnancy diagnosis and abnormalities of contents of tubular tract. In 1980, Palmer and Driancourt reported for the first time, real time ultrasonography for diagnosis of pregnancy in the mare. This report generated considerable interest among veterinarians and scientists about ultrasonography and this new discovery contributed significantly towards understanding of functioning of the uterus and ovaries of mare (Chevalier and Palmer, 1982; Ginther, 1983; Ginther and Pierson, 1984a & 1984b), cows (Pierson and Ginther, 1988, Reeves et al., 1984) and other species (Buckrell, 1988; Driancourt, 1991). The ultrasonography is fast replacing the age-old procedure of rectal palpation of genital tract for pregnancy diagnosis (Pieterse et al., 1990). This technique has been used and advocated for the use in the academics and field practice.

The association of weeds with field crops was started when ancient man started cultivating plants as crops commercially. However, type of weed flora went on shifting with the passage of time, due to changing climatic conditions, cropping pattern, agronomic practices, crop cultivars etc. When crops are cultivated invariably a variety of volunteer undesirable vegetation come up simultaneously which competes with the crop for all growth factors viz., nutrients, soil moisture light, space etc.

Definition of Weed

Weed is a plant that originates under a natural environment and in response to imposed and natural environments, evolved and continues to do so as an interfering associate with our desired plant and activities.

Weed is a plant growing out of place. They are unwanted not useful, persistent and prolific, effectively competing with the beneficial and desirable crop plants for space, nutrients, sunlight, and water, interfere with agricultural operations and thereby reducing the yield and quality of produce.

Weeds are unwanted and undeserved plants that interfere with the utilization of the land and water resources and thus adversely affect crop production and human welfare. Thus a plant out of its place or a plant growing where it is not desired is a weed. This definition was given by Buchholtz in 1967. E.g. Bajra is a weed in pulse, pulse is a weed in bajra, tomato is a weed in brinjal field. Weed is defined as the unwanted, undesirable plant growing out of their proper place which interfere with the utilization of natural resources, prolific, persistent, competitive, harmful and even poisonous in nature and can grow in adverse climatic conditions (Jethro Tull: Father of Weed Science).

Weediness: Weediness is defined as the state or condition of a field, flower beds, lawns and so forth in which there is an abundance of weeds.

Weeds are plants that are unwanted in a given situation and may be harmful, dangerous or economically detrimental. Weeds are a serious threat to primary production and biodiversity. They reduce farm and forest productivity, displace native species and contribute significantly to land and water degradation. The costs of weeds to the natural environment are also high, with weed invasion being ranked second only to habitat loss in causing biodiversity decline.

India is one of the chief carpet wool producing and exporting countries of the world. A large quantity of carpet wool is exported to the developed countries. Wool production in Indian subcontinent is mainly dependant on distinct type of sheep producing wool in a particular geographical area. For example small and course wool is produced by Bikaneri breed in North Western India, course wool by Deccani breed and hair type breed by Mandya breed in Peninsular India and fine wool is produced in Himalayan region. In general, tropical breeds of sheep are mainly producing course wool which is highly suitable for carpet manufacture. Most of the Indian sheep breeds are producing low fleece yield. The annual total yield of greasy wool is in the range of 1-1.5 Kg. Overall great quantity of wool is produced in southern hemisphere but consumption is in northern hemisphere.

There are manyreasons for using computerstoday. Word processing is area which has proved computers to be powerful than ever. There are many different kinds of word processors availabletoday, however, most share the same basic functions and do not require advanced computeror typing skills to use. These basicfunctions include typing, savingdocuments,openingdocuments, copying, pasting, cutting printing, checking spelling, etc. The commonly used word processors include Microsoft Word, ClarisWorks, Word Perfect, Word Pad, Apple Works, etc.

4.1 Microsoft Word

4.1.1 Introduction

Microsoft Word, or Word as it is commonly known, is a software application that allows the user to perform word processing. The word processing means the creation, input, editing, and production of documents and texts by means of computers systems. Microsoft Word allowthe user to format text with attributes such as bold, italics, font size, and margins. It is part of the Microsoft Office suite of applications and is a highly popular programme for the workplace.

Microsoft Word was first released in 1983 under the name Multi-Tool Word for Xenix systems. Versions were later writtenfor several other platformsincluding IBS PCs running DOS in 1983,the Apple Macintosh in 1984 and Microsoft Windows in 1989. The latest release is Word 2010.

1.1 Introduction

The human population is growing rapidly at an alarming rate, disproportionately to the production of food supplies, which will necessitate production of more food in the near future. The human population has already crossed the 7 billion mark and is expected to rise over 8-10 billion by 21st century. More than 800 million people are reported to suffer from malnutrition (Matson et al., 1997).  Thereby necessitating the need for more food production. Presently, agriculture faces the double challenge of feeding a fast growing population and at the same time prevents the degradation of the agricultural resource base. There appear to be two options for developing countries; either to improve agriculture through modernization, by emphasizing pesticides, fertilizers, machinery and modern varieties of crops; or use sustainable agriculture, promoting improved traditional, small-scale techniques (Pretty, 1999).

The term nanotechnology, buzzword of present day science owes its origin from the Greek word ‘nano’ literally meaning dwarf. When it is expressed in terms of dimension one nanometer equals to one billionth of a meter (1nm = 10-9 m). A nanometer is a thousandth of a thousandth of a thousandth of a meter, about 60,000 times smaller than a human hair in diameter or the size of a virus, a typical sheet of paper is about 100,000 nm thick, a red blood cell is about 2,000 to 5,000 nm in size, and the diameter of DNA is in the range of 2.5 nm. Therefore, nanotechnology deals with matter that ranges from one-half the diameter of DNA up to 1/20 the size of a red blood cell. 

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.

Over the last decade, area under horticultural crops grew by 2.60% per annum and production 4.8% per annum. During 2017-18 total 311.71 million tonnes horticultural crops were harvested from 25.43 million hectare area. India is 2nd largest producer of fruits in the world after China, with average productivity at 14.97 t/ha. Fruits alone were cultivated almost in 6.5 million hectare area and production of 97.38 million metric tons, (Anonymous, 2018).

Of the 7 billion global population, about 800 million do not have enough food to eat and majority of the them live in developing countries. By 2050, the world population is estimated to reach 9 billion. Plant pests and diseases are responsible for losses of 20 to 40% of global food production. Due to increasing global trade and a changing climate, plant diseases pose a major threat to food security today than ever before. Agriculture will have to cope with weather fluctuations that can affect the survival, distribution and multiplication of plant pathogens apart from shift in pathogenic microbial flora. Emergence of new races of pathogen potentially threaten the production of food. To cite an example, migration of 13 -A2 clonal lineage of Phytophthora infestans from Europe, during 2013, devastating tomato and potato in India. Plant pathogens also impact on environment sustainability, forest health, recreational horticulture, human and animal health.

The science of plant pathology can play a much needed role in alleviating hunger and malnutrition through development of affordable solutions for devastating plant diseases leading to increase in food production. It hold promise to ensure quality produce by containing microbial invasions and toxin contamination of food crops. Plant Pathologists have an important role to play in meeting the food security need of the nation by developing technologies for ensuring proper crop health. There is an urgent need to produce more food per unit area for feeding rapidly increasing human population. We need to act ahead of pathogens in our efforts to ensure normal crop yields. Cutting edge biotechnologies such as CRISPR gene editing systems and RNA interference are being exploited to rapidly developed crop varieties having resistance to specific pathogen races.

Crop protection has come a long way from predominantly chemical based approaches to more environment friendly IDM technologies including green chemistry. There is a need to develop bio-intensive modules for management of diseases. Decision support system need to be developed for important diseases for their timely, more efficiently management. There is need to adopt information technology at a larger scale to facilitate quick dissemination of new crop protection solutions among the farmers and other stakeholders.
