Introduction

Cowpea, {Vigna unguiculata (L.) Walp.} is an important food legume in the semi-arid tropics covering Asia, Africa, Southern Europe and Central and South America (Henriet et al., 1997; Mortimer et al., 1997; Van Ek et al., 1997). It is a drought tolerant and warm weather crop. Therefore, well adapted to the drier regions of the tropics where other food legumes do not perform as well. It fixes atmospheric nitrogen and grows well even in the poor soils with more than 85% sand and with less than 0.2% organic matter and low levels of phosphorus (Kolawale et al., 2000 and Sanginga et al., 2000). Also, it is shade tolerant and therefore, compatible as an intercrop with maize, millet, sorghum, sugarcane and cotton as well as with several plantation crops (Singh and Emechebe, 1998). Coupled with these attributes, its quick growth and rapid ground cover checks soils erosion and in situ decay of its roots and nitrogen rich residues improves soil fertility and structure which together have made cowpea an important component of cropping system in the dry savannas of the sub-Saharan Africa (Carsky et al., 2001 and Mortimer et al., 1997).

Cowpea is cultivated in about 14 million ha world wide with about 5 million tons annual production. However, a substantial part of the cowpea production comes only from few countries. Nigeria is the largest producer and consumer of cowpea with about 5 million ha area and about 3 million tons production annually. Niger Republic is the next largest producer with 3 million ha and over 1 million ton production. Northeast Brazil grows about 1.5 million ha of cowpea with about 500.000 tons production. In the southern USA about 40,000 ha of cowpea is grown with an estimated 45,000 tons annual production of dry cowpea seed and a large amount of frozen green cowpeas. Even though exact statistics are not available, India is the largest cowpea producer in Asia and together with Sri Lanka, Pakistan, Nepal, Bangladesh, Thailand, Indonesia and other far eastern countries, there may be over 1.5 million hectares under cowpea in Asia.

The British administration, with an intention of ruling over India, viewed Allahabad as a city of the future. They saw the prospect of a glorious future in Allahabad and planned the city in a manner to project it as a center of Education, Culture and Administration. With religious bearings already an established feature, this, added to its charm and growing potential. This chapter covers the crucial ninety years of development in the city before Independence. The observations and findings are recorded and commented upon, these help in analyzing the exact nature of rise and decline, this city faced in years to come.

ALLAHABAD : AN ESTABLISHED CENTER OF EDUCATION AND CULTURE (1858-1947)

In the following section the focus is on the Kumbh mela, its rising popularity and the presence of cultural institutes, their functioning and role in developing the city into a prominent urban centre. During the period 1858-1947, the importance of Kumbh grew, it is evident from the records that the number of pilgrims visiting Allahabad during the Magh increased.

Metabolic diseases assume the greatest significance in dairy cows and buffaloes during transition period, and occur due to imbalance in input and
output of production. The main reasons of occurrence of metabolic diseases are an imbalance between the rate of ‘input’ of dietary nutrients and ‘output’
of production.

In the present study, chicken (broiler) meat mince was used as protein sources. Incorporation of chicken meat minceat10, 20, 30, 40 and 50percent levelweretriedbesidesotheringredientswhichwereaddedincontrol.Chicken Biscuits incorporated with 20 per cent CMM were preferred the most on the basis of their sensory evaluation. Asthe chicken incorporated biscuits have not been reported in India and abroad. Majority of biscuits available in market are prepared from cereal (refined wheat flour), which has very low protein content & lack lysine, threonine & tryptophan essential amino acids. The biscuits thus developed can contribute good amount of nutrients especially protein if consumed in place of cereal (refined wheat flour) biscuits. The developed products can be used for feeding programme at institutes and school going children and elderly people, who are more prone to malnutrition particularly due to protein with essential amino acids deficiency. Chicken meat is also rich in threonine, tryptophan and lysine. Thus development of chicken incorporated biscuits using chicken meat and wheat flour would provide a nutritious, convenient and ready to eat food item. With an aim to develop biscuits by incorporating the chicken meat, the present study was planned. It was concluded that the biscuits with 20 per cent chicken meat mince and wheat flour would provide a nutritious with sufficient amount of essential amino acids (lysine, tryptophan and threonine), convenient and ready to eat food item. The cost of production of biscuits with 20 per cent CMM worked out to be Rs. 82.40 per kg.

Supply chain management (SCM) is essential for the food industry because it involves the coordination and management of various activities from food procurement to consumption. The food supply chain is complex and involves many stages, from the production of raw materials to packaging, distribution and sales. Therefore, effective food supply chain management is essential to ensure that food products are delivered to consumers efficiently, cost-effectively and with maximum food safety.
One of the biggest challenges in food chain management is food safety. Foodborne illness is a major concern and food manufacturers must implement strict quality control measures at every stage of the food supply chain. This includes testing and monitoring for pathogens, maintaining proper storage and transportation conditions, and ensuring that all equipment is cleaned and  disinfected to prevent contamination.
Another challenge is food waste. Food products have a limited shelf life and Managing inventory levels is essential to minimize waste and spoilage. Effective food supply chain management requires careful planning and coordination between suppliers, manufacturers, distributors, and retailers to ensure that products are delivered to consumers before their expiration date.
Efficient management of logistics and transportation is another essential aspect of supply chain management. Food products often travel long distances before reaching consumers, and companies need to ensure that products are delivered to customers quickly and efficiently. This requires careful planning and coordination of transportation routes, scheduling, and delivery times to minimize delays and disruptions.

Introduction
Urban sustainability has become a critical focus as the global population increasingly concentrates in cities. With over 56% of the world’s population residing in urban areas, cities are significant drivers of economic growth and innovation but also contribute disproportionately to environmental degradation, resource depletion, and social inequities. Urban sustainability aims to balance economic, social, and environmental dimensions, ensuring that cities are livable, resilient, and capable of meeting the needs of current and future generations. Information Technology (IT) is pivotal in advancing urban sustainability by enabling smarter resource management, reducing environmental footprints, and fostering inclusive and equitable development.

Biochemical tests are vital diagnostic tools in fish health laboratories across India, helping to accurately identify and differentiate bacterial pathogens responsible for aquatic diseases. These tests complement culture-based and morphological analyses by revealing the metabolic and enzymatic functions of bacterial isolates. Given India’s broad aquaculture landscape with varied species and environmental conditions, rapid biochemical diagnostics are crucial for effective disease control and reducing economic impact.
Indian labs, especially those near coastal regions, aquaculture ponds, and freshwater bodies, routinely use these tests to confirm bacterial species isolated from fish. After isolating colonies and performing Gram staining on samples from fish gills, fins, skin lesions, internal organs, or mucus, key colonies are subjected to standard biochemical assays. These assays examine traits like carbohydrate fermentation, enzyme production, and substrate utilization to pinpoint genus or species. Frequently encountered bacteria include Aeromonas, Vibrio, Edwardsiella, Streptococcus, Flavobacterium, and Pseudomonas.
The oxidase test detects cytochrome c oxidase; Aeromonas and Vibrio are oxidase-positive, while Edwardsiella is not. The catalase test identifies catalase enzyme production, distinguishing catalase-negative Streptococcus from other Gram-positive cocci.
The Triple Sugar Iron (TSI) agar test, widely used in Indian labs, checks glucose, lactose, and sucrose fermentation along with hydrogen sulfide (H?S) production. For example, Edwardsiella tarda from Tamil Nadu and Andhra Pradesh produces black precipitate and ferments glucose. The indole test identifies indole production from tryptophan—many Aeromonas isolates from West Bengal and Odisha are indole-positive.

Modern agriculture prioritizes intensive crop production in a sustainable manner to meet the growing demand for food. However, the increasing prevalence of biotic stresses such as fungal, bacterial, and viral pathogens, along with insect pests and nematodes, poses a serious threat to agricultural productivity. Conventional pest management practices, rely heavily on synthetic chemicals, that have raised concerns due to environmental toxicity, pest resistance, and health risks. Consequently, scientific community is shifting their focus to ecofriendly alternatives to ensure agricultural sustainability. Plant growth-promoting microorganisms, as bioinoculants have gained widespread recognition for their potential to enhance plant development and reduce the harmful effects of agrochemicals. Despite their promise, the field application of bioinoculants remains limited due to poor shelf-life, rapid degradation and instability under field conditions. The integration of nanotechnology with microbial inoculants, referred to as nanobioinoculants, offers an innovative and sustainable solution to these limitations through the development of smart products, and efficient delivery systems. This chapter highlights the functional synergy between nanomaterials and bioinoculants, integration strategies, mechanisms of action, and their role in managing biotic stresses. Nanobioinoculants, including biogenic nanomaterials, nanobio conjugates, and encapsulated bioinoculants offer enhanced plant protection by producing antimicrobial compounds and

Financial modeling is one of the most highly valued, but thinly understood, skills in financial analysis. The objective of financial modeling is to combine accounting, finance, and business metrics to create a forecast of a company’s future results. A financial model is simply a spreadsheet, usually built in Microsoft Excel, that forecasts a business’s financial performance into the future. The forecast is typically based on the company’s historical performance and assumptions about the future and requires preparing an income statement, balance sheet, cash flow statement, and supporting schedules (known as a three-statement model, one of many types of approaches to financial statement modeling). Financial modeling skills are essential for anyone pursuing a career in finance. Models synthesize a vast amount of information to help users make better investment and business decisions. The modeler’s technical acumen

A detention reservoir temporarily stores storm runoff and releases it gradually at a controlled rate, thereby reducing the peak discharge reaching downstream channels and communities. Unlike a conventional conservation reservoir, its principal function is short-term flood moderation rather than permanent water storage. Its performance depends on basin capacity, inlet and outlet arrangements, catchment response, design storm, allowable downstream discharge, and available drawdown time. This chapter explains the concept, purposes, and functioning of detention reservoirs and distinguishes them from ordinary storage reservoirs. It covers their classifications, site requirements, storage estimation, outlet design, routing principles, benefits, limitations, maintenance, and application in rural watersheds, urban drainage systems, and integrated flood-control programmes.

Marriage and family dynamics concern the structures, relationships, roles and processes through which families function and change. This chapter examines forms of marriage and family, mate selection, family authority, role allocation, communication, adjustment and decision-making. It considers changing family patterns, marital relationships, parenting styles, family life-cycle stages, conflict, divorce and the influence of social and cultural factors. Questions also address family welfare, interpersonal relationships, responsibilities, values and the challenges experienced by contemporary families. By connecting theoretical concepts with everyday family situations, the chapter helps learners understand how individuals and families adapt to transitions, maintain relationships and promote the well-being of their members.

Animal husbandry faces increasing pressure to produce safe milk, meat and eggs while improving animal welfare and reducing environmental impacts. Traditional observation-based management is increasingly inadequate for large and complex livestock systems. This chapter introduces digital transformation through Precision Livestock Farming, which combines IoT devices, smart sensors, wearables, computer vision, artificial intelligence, machine learning and digital twins. Continuous animal-centred data enables timely decisions concerning health, reproduction, feeding, behaviour and welfare. The chapter explains how digital technologies can support early disease detection, efficient resource use and improved productivity across commercial and smallholder farms, creating more profitable, sustainable and welfare-conscious livestock systems.

Predictive modelling of plant growth can help farmers and researchers improve crop management, resource utilization and production planning. This chapter examines machine learning approaches for predicting important plant growth characteristics. It introduces plant growth fundamentals and the environmental and management factors that influence development. The chapter covers the machine learning workflow, including data acquisition, preprocessing, feature engineering, model development and evaluation. Supervised learning, unsupervised learning and deep learning approaches are considered for predicting plant height, biomass, canopy development, leaf area and yield-related characteristics. Data from IoT devices, drones and satellite imagery can strengthen prediction models. The chapter also discusses precision agriculture applications, limitations and emerging technologies such as explainable AI, digital twins and edge AI.

Escherichia coli is an important model organism for studying microbial metabolism, metabolic regulation, and metabolic engineering. This chapter introduces the use of metabolomics to investigate the metabolic architecture and physiological responses of E. coli. It examines metabolite profiling, central carbon metabolism, metabolic pathways, environmental responses, and metabolic flux analysis. The chapter explains how metabolomic data can reveal changes in cellular metabolism and support the identification of pathway bottlenecks and regulatory mechanisms. Applications in microbial biotechnology, recombinant production, metabolic engineering, and optimization of fermentation processes are considered. The chapter demonstrates how E. coli serves as a useful experimental system for connecting metabolite changes with cellular function.

Laboratory and exotic pets require specialized handling because their anatomy, behaviour and physiological characteristics differ considerably from conventional domestic species. This chapter covers restraint, physical examination and medication of laboratory animals, birds and exotic pets, including reptiles. Physical examination involves systematic evaluation from head to tail, assessment of oral and external structures, palpation and measurement of physiological parameters. Special attention is given to reptile examination, where shells and species-specific anatomy may complicate physical assessment. Diagnostic imaging can be particularly valuable. The chapter emphasizes minimizing stress, selecting appropriate restraint methods and adapting clinical procedures to species-specific requirements.

INTRODUCTION

Biodiversity  refers to varieties of life on the Earth including  animals, plants, microbes and genes within them, their habitats and ecosystems and all variations within a given ecosystem, biome or entire planet. Biodiversity is the basis of life on Earth, important for the functioning of ecosystems, provides us with products and services without which we cannot live. Consider our food range in India. It ranges from Indian bread (chapatti), rice and rice products and related curries and other varieties made out of different vegetables. These food items are made of wheat, paddy, maize, bajra, ragi, potato, tapioca, sweet potato,  yams and corns, pulses like pigeon pea, green and black gram, Bengal gram, soyabean, vegetables like tomato, brinjal, cucumber, pumpkin, drum stick, bitter gourd, snake gourd, bottle gourd and various gourds, French bean, amaranth and  so many leafy  vegetables, spices and condiments like chilly, cardamom, ginger, turmeric, pepper, nutmeg, clove, cinnamon, cumin, coriander, fenugreek etc. This is the diversity of food we have in India. Similarly, all other groups such as herbal medicine, ornamentals, timber and non-timber species are also very diverse.

4.1 Introduction

Discharge is also called as rate of flow. Discharge is defined as the volume of water flowing through a cross section in a unit time. It can be expressed as cubic metre per second (cumec), cubic feet per second (cusec), litre per sec (lps) etc. One cumec is equivalent to 35.5 cusecs or 1000 lps. The measurement of discharge is very important in everyday life starting from deciding the amount of irrigation to be supplied to a crop at a particular growth stage, or amount of water supply for domestic and industrial uses, for flood control and power generation etc. It plays a vital role in water resources planning. If a stage-discharge (also called as gauge-discharge) relationship for a particular gauging site is developed, then daily measurement of discharge in the gauging site is not required. Discharge can be estimated from the developed relationship of discharge versus stage if the measurement of stage is known.

Introduction

Cereal crops are of global importance and the lifeline of the humane civilization. Nutritionally, they are important sources of dietary protein, carbohydrates, Vitamin B complex, Vitamin E, iron, trace minerals and fiber. Major cereal crops produced worldwide include wheat, rice, maize and millets. Among them, wheat, maize and rice together comprise at least 75% of the world’s grain production. More than 70 per cent of the cereal crop produced in developed countries is fed to livestock whereas, in developing countries, 68-98 per cent of the cereal crop is used for human consumption (Chaven and Kadam, 1989). Rice is the most important and widely cultivated crop in the world and is the staple food for about 60% of the world’s human population. It is basically a crop of humid tropics, but it varies widely in physiological adaptability, hence grown successfully both in tropical and temperate conditions. Wheat (Triticum aestivum L.) is the another important and widely cultivated food crop in the world and important rabi crop of our country. In India, wheat is the second stable food crop after rice which contains more protein than any other cereals. Maize is an important kharif cereal in hilly, sub-mountained and even in plain regions of our country where it forms staple diet of the people.

Introduction

The demand for butter as table spread has declined due to high cost, poor spreadability at low temperature, high saturated fat and cholesterol content, changing life style and increased demand for healthy products. Today food industry is actively involved in new product development, this includes new formulations and imitation of foods being designed to compete with or replace existing products based on their superiority in convenience, cost and quality. The wide acceptance of bread in regular diet among urban consumers (75 percent of all household) reflects around 8 percent rate of growth in bread consumption. With this increase, the requirement of a suitable spread to complement has also increased. Table spreads include a variety of spreadable semi-solid products such as fat spreads, cheese spread, peanut butter etc. Butter has also been blended with vegetable oils/fat to produce a product that retains dairy qualities of butter with enhanced spreadability.

Abstract
The western Himalayan region is rich in a variety of natural resources owing to the existence of a range of biophysical and climatic interactions. Mountain inhabitants have been living in harmony with these natural resources for generations to meet their subsistence needs out of these resources.  However, recent decades have witnessed a substantial imbalance between man and nature that has adversely affected the livelihood of native people. Several anthropogenic and natural factors are responsible for this change. Furthermore, the exposure of mountain societies to outside world has opened up a number of new livelihood options based on both natural resources and other forms of human capital. The local people have adopted some livelihood practices suiting to the changed conditions at the expense of the age-old agri-silvi-pastoral mode of livelihood. There is an emerging challenge for policy makers and planners to make developmental interventions and tailor made livelihood options suiting to the changed scenario. Several government and non-government organizations and other agencies initiated a number of programmes that focus on natural resource management vis-à-vis livelihood improvement in the region. However, for want of cause and effect analysis many of these programmes are not yielding the desired results. This chapter provides an overview of the traditionally important livelihood practices of the western Himalayan region and some of the emerging livelihood supporting activities based on natural resources of the region. A case study of Bhimtal lake catchment where transformation of traditional livelihood has taken place at a rapid pace due to the influence of tourism and urbanization has also been included to highlight the emerging scenario. The paper suggests some useful policy options for planning livelihoods in the western Himalayan region of the country.

It is well recognized that sustainable management and sustainable livelihoods are inseparable. If neglected and if the present trends are not corrected in time, everyone’s future is threated. On the other hand, there is increasing recognition of living examples and demonstrated evidences of how the eco agricultural practices can help provide a solution to some of the major problems of today and tomorrow. Also, the main stream international agencies are emphasizing that agro-ecological approaches are the way forward. What the policy makers, farmers and people would like to know is How !it has been our experience that in most countries of the developing world the answer to ‘How’ of eco-agricultural is being demanded!

Theory

Rural Development: The economic betterment of people as well as greater social transformation. The efforts for rural development comprises the direct and indirect involvement of people at the grass root level for development of agriculture/animal husbandry, industry, communication, education, health and allied sectors. 
Democratic Decentralization: To ensure people’s participation in rural development programmes, democratic decentralization has been the core principle of the government since 1957. In the process, people’s participation in all developmental activities has been the unique phenomena to find out the solutions of their problems.
Panchayat Raj: On the principle of democratic decentralization, Panchayat Raj institutions were launched in 1957 as per the recommendations of Balwant Rai Mehta Committee. Under this, the government has derived its authority from the people, and distribute to some extent to the people for decision and action at the local level called Panchayat Raj.

10.1. Introduction

During last few decades dairy animal production has been intensified several folds, along with this reproductive problems have also increased. For efficient dairy animal production, the cow should show regular reproductive activities like cyclic breeding activity, pregnancy at appropriate time, give birth of a live healthy calf and again pregnant after sometimes. If any of these activities are inadequate, then it substantially affects the profitability of the farm. There is an ample scope of improvement of these reproductive setbacks through traditional breeding, feeding and management. However, reproductive problems can be minimized by the use of recently developed reproductive techniques. It not only minimizes reproductive problems, but also improves the reproductive efficiency of the dairy herd and better exploitation of the genetic potential of high merit animals.

Introduction

Packaging and storage are two most important operations in post harvest supply chain of fresh and processed fruits and vegetables. The self-life, damage, loss, sale and profit from commodities depend on storage and packaging parameters. The primary objective of packaging of fruits and vegetables is to protect the contents during storage, transportation and distribution against deterioration, which may be physical, chemical, or biological. Packaging is hence provided at the point of production or processing or at distribution centers. Though packaging forms the last link in the chain of production, storage, marketing and distribution, it still plays an important role in delivering the contents safe from the ‘‘farm gate to the consumer plate.’’ Increase in production can have an impact on the consumer only when the food is wholesome, unadulterated and available under hygienic conditions at an economical price.

Introduction

Labour markets, poverty and inequality in the growth process
 
The theoretical discussion on the changes in the incidence of poverty and inequality in the growth process of agrarian economies from low levels of income has been a major topic in development economics. The impact of growth is delineated through the labour market, and any predictions about the impact on poverty and inequality must be based on some implicit or explicit view of the structure of labour markets and their functioning.

Setting price is a critical component of successful marketing. Vegetable growers have a greater level of control than most other growers over marketable yields, input costs and price. The closer a grower is to the consumer, the more control over price the grower has. Buyers perceive price to represent value of the product. Underpricing, or pricing too low, gives the perception that the product is inferior, while setting the price too high often drives customers away. Many growers make the mistake of setting the price too low at the beginning of the marketing season when competition is less and demand is strong and then find it difficult to increase price later in the season. Before setting price, gauge the level of competition and the consumer demand for your product. For example, organic produce may have a stronger demand in urban areas, so prices can be set at a higher level. Also, early-season produce, such as tomatoes, has high demand with little competition in most markets, resulting in a higher price range.

2.1 Soil and Climate

Pomegranate grows well in sandy-loam and well-drained soils having a pH of 7.5. It can also be grown on light soils. Quality and colour development in light soils is good but poor in heavy soils. It tolerates salinity up to 9.00 EC/mm and sodicity 6.78 ESP. Even it can be grown well in slightly saline soils as it is considered a saline-tolerant plant (Patil and Waghmare 1983; Rao and Khandelwal 2001; Ram Asrey et al., 2002). Accumulation of salts, in excess of 0.5% of the soil mass causes dying off of growing roots. Interestingly, application of Paclobutrazol (250 ppm) was reported to reduce salinity damage (Saeed 2005). The presence of water-soluble salts like sulphates and chlorides and ex- changeable sodium negatively affect root formation.

In countries like India where majority of the population are vegetarians, leguminous vegetables serve as the major source of protein in the diet. In the developing third world countries, especially for the poor, the major protein source in the diet are vegetable legumes. Most leguminous vegetables are rich in phosphorus, calcium, iron and a number of essential vitamins. Crops like soybean, groundnut and Bamabara groundnut are also rich in fats which are needed by the body to absorb vitamin A.

The adoption of modern agricultural technologies has culminated into serious problems of pesticide resistance in major pests, resurgence in minor pests, elimination of populations of natural parasites, predators and pollinators, environmental pollution, pesticide residues in food chain and health hazards. World Health Organization (WHO) estimates one million pesticides poisoning cases and 20,000 deaths every year globally. This is due to high pesticide residues in food chain including cereals, pulses, vegetables, fruits, milk and milk products (including mother’s milk), fishes, poultry, meat products and water. Twenty five per cent of Indian food products contain pesticide residues above tolerance level compared to only 1.2% globally.

Sustainable agriculture or organic farming wherein biological inputs are maximum and chemical inputs are minimal, is drawing the attention of farmers across the world including India. For replacing chemical fertilizers, which supply plant nutrients by organic manure, the basic requirement is the availability of raw material i.e. the organic matter or biomass that can be decomposed to organic manure. The question that is often asked is what are the different sources of available biomass and how much of it is available? Different sources of biomass can be categorized as

Tomato
1. Damping off
Pathogen
Pythium aphanidermatum
Fusarium spp.
Sclerotium spp.
Symptoms
Damping off is the most important disease of tomato. Several seed and soil borne fungi can kill before the tender redical and plumule establish in the nursery bed. The pre emergence damping off and seed rotting is the usual cause of poor seedling stand. This type of damping off causes hidden loss but the post emergence damping off is more serious problem. Seedlings get infected near the soil line (collar region) after emergence and give wire stem symptoms. The tissue become soft, water soaked and weak causing the seedlings fall over and later on they die. The entire action is so fast that leaves remain green but they are unable to stand further.

2.1 Quantitative Classification

It the data are classified on the basis of phenomenon which is capable of quantitative measurement like age, height, weight, prices, production, income expenditure, sales, profits, etc., it is termed as quantitative classification. The quantitative phenomenon under study is known as variable.  For example the daily incomes of different retail shops in a town may be classified as under.

Introduction

On 29 January 2000, the Conference of the Parties to the Convention on Biological Diversity adopted a supplementary agreement to the Convention known as the Cartagena Protocol on Biosafety. The Protocol seeks to protect biological diversity from the potential risks posed by living modified organisms resulting from modern biotechnology. It establishes an advance informed agreement (AIA) procedure for ensuring that countries are provided with the information necessary to make informed decisions before agreeing to the import of such organisms into their territory. The Protocol contains reference to a precautionary approach and reaffirms the precaution language in Principle 15 of the Rio Declaration on Environment and Development. The Protocol also establishes a Biosafety Clearing-House to facilitate the exchange of information on living modified organisms and to assist countries in the implementation of the Protocol.

Abstract

While, life on Earth is dependent on microbes for many essential services, microbes are intimate partners in virtually every life process of plants by way of mobilization/acquisition of nutrients, out-competition and antagonism of pathogens, plant stress alleviation, plant growth promotion, co-metabolism, degradation of toxins, etc. Exploitation of such interactions between microbes and plants and optimization of plant microbiome could allow farmers to apply less chemical fertilizer, and pesticides besides improving overall plant health which paves the way for sustainable development. What is less appreciated, and less well understood, is the mechanism of microbes exerting such benefits to the plants. A greater understanding of how plants and soil microbes live together, communicate, build innate plant immunity, triggers hormone synthesis and benefit each other can therefore provide new strategies to improve plant productivity, while helping to protect the environment and maintain global biodiversity.

Abstract

The nutrition of tobacco plants relies upon the plant genotypic variation and soil characteristics which also influence the various microflora that inhabit the rhizosphere. The investigations were aimed to analyze the role of native and inoculated plant growth promoting bacteria on the uptake of major plant nutrients viz., nitrogen, phosphorus and potassium and also their supportive nature in reducing the infection caused by  Pythium aphanidermatum, the damping-off fungus of tobacco in nursery. Rhizosphere microorganisms include PGPR viz., Azotobacter, Azospirillum, Pseudomonas and Bacillus, AM fungi and Streptomyces. The addition of these microbes as bioinoculants in tobacco integrated nutrient and disease management resulted in better quality tobacco worth premium price.

Abstract

Cyanobacteria comprise a group of photosynthetic prokaryotes, which exhibit versatility in their morphological, biochemical and molecular characteristics and represent an untapped source of novel metabolites and genes. Their structural-functional flexibility makes them successful in diverse and extreme environments including high temperatures or levels of UV light and salinity, and co-exist in symbiotic/parasitic/mutualistic associations with various members of Plant and Animal kingdom. The intracellular colonization of cyanobacteria in wheat and rice roots and their potential as plant growth promoting agents for several crops, besides rice, has led to the deployment of novel formulations of cyanobacteria and agriculturally useful bacteria as biofilms and disease suppressive options in field studies.

Summary

Idealistic theories of property are projected to offer general and explicit statements of the justification for deciding legal and moral questions about the status property claims. Debates over property rights in biotechnology were occasioned by specific legislative proposals such as the US Animal Patent Act of 1986, and by filing of patent applications for DNA sequences and processes in the early 1990s. While these debates make sporadic petition to philosophical theories of property, moral claims were entwined with questions about filing requirements, tests for worth, and the rules for licensing and defending patents. The comparative scarcity of discussion on intellectual property at that time dictated the general approach of the chapter: Review basic philosophical approaches to property rights, and speculate on how one might use these approaches in constructing an argument pertinent to agricultural biotechnology. This chapter deals with different approaches to intellectual property in the field of Plant Sciences especially the Biotechnology. It incorporate many different types of intellectual property and a variety of incommensurable values play a role in the justification of intellectual property.

Summary

Multicellular organisms are made up of diverse set of cells. Cells respond to the changes in the particular microenvironment by means of cellular communication. This cell-cell communication is extremely important for the development, maintenance and survival of the organism. This communication is equally important for the unicellular organisms. Cells communicate to one another and respond to the environmental changes using diverse chemical languages, as discussed in this chapter. However, in many cases like multicellular organisms, cell communication is primarily mediated by specific receptor(s) expressed on the cell membranes. These receptors bind to the extracellular signaling molecules (called ligands) and activate specific signaling pathways to bring about particular cellular responses. These different receptors, ligands and signaling pathways are briefly discussed here.

Significant transformation took place in the traditional variety improvement and seed production programmes in the sixties and modernized with initiation of hybrid development programme in maize, sorghum and pearl millet, as well as with the introduction, breeding and release of semi dwarf high yielding varieties of wheat and rice. To support the release of varieties and their quality seed production Indian Parliament enacted Indian Seeds Act in 1966. Subsequently, National Seeds Corporation was launched by Government of India for scientific growth of seed industry in the country. All these developments led to the green revolution and country attained self-sufficiency in food crops.

Abstract

Despite several controversies surrounding the genetically modified (GM) crops or their produce, the production of such crops is constantly increasing, especially in developing countries. To regulate the GM produce in the market, several countries have set very strict regulatory procedures for the approval to grow, import or utilize these GM crops as food or food ingredients. Hence, for regulatory compliance on GM labeling and identification of genetic traits, the development of reliable, sensitive and precise detection assays have become essential. The detection of GM produce is carried out by detecting either the inserted foreign DNA or the novel transgenic protein specifically expressed in GM crops. This article broadly focuses on some DNA and protein-based detection methods employed for GM produce and significant current advances in such detection technologies.

Abstract

Pruning is the most important cultural operations in tea cultivation. Time of pruning affects health of bush, incidence of pests and disease, yield and distribution of crop. Root starch reserve at the time of pruning affects the recovery of bush and hence considered as the most crucial factor for deciding time of pruning. Downward movement of photosynthates was found maximum in December and January, thereby maximizing the starch reserve in roots. Maximum recovery of tea bush and minimum loss in annual crop was found when pruned during December – January. Pruning in remaining months (February – November ) may result in crop loss to the tune of 5 per cent – 37 per cent in plain areas. Clonal varieties differ in root starch accumulation during winter months hence pruning time of individual clone needs to be decided accordingly to enhance recovery of plants.

Abstract

Tea [Camellia sinensis (L.) O. Kuntze], of family Theaceae, is an important cash crop  worldwide. It is an evergreen shrub cultivated in humid and sub-humid tropical, sub-tropical, and temperate regions of the world, and grows mainly on acidic soils. Due to limitation of expansion of tea cultivation in new land, import of low cost high quality tea, increasing vertical productivity is the best option of Indian tea Industry. The primary need of the tea industry today is to develop high yielding clones with better quality and stress tolerance potential. Conventional tea research has contributed appreciably to the genetic improvement of tea over the past several decades, but it is time-consuming and labor intensive.

Introduction

Indigenous peoples established distinct systems of knowledge, innovation and customary practices from their centuries old interactions with the local biodiversity and environment, relating to the uses and management of local natural resources. Today, this knowledge is looked as an important resource for research and development in different areas such as pharmaceuticals, agriculture, veterinary, jewelry, fashion and cosmetic products. This has led to rampant exploitation of such knowledge disregarding the customary practices and rules of indigenous peoples holding and preserving such knowledge as well as the biodiversity and natural resources. As a consequence, the traditional knowledge is under threat of being misappropriated or lost.

Antibodies are a group of glycoproteins having a globular compact structure. They are known as immunoglobulins. On the basis of their experiments, Tiselius and Kabat, in 1939, demonstrated that most antibodies are found in the g globulin fraction of serum proteins. When serum from rabbit, immunized with ova albumin, was subjected to electrophoresis, it showed a peak for g globulin (Fig. 4.1). Studies have revealed that the major part of IgG is found in the g globulin fraction of the serum proteins. Other fractions, a and b, too, have other immunoglobulins along with small part of IgG.

With the evolution of Information and Communication Technology (ICT) in Agriculture as the major employer of Ugandans population with over 82% of the population, agricultural information is a key component in improving small-

Globally, 2 billion children under the age of five suffer from diarrhoea, of which, more than 50% of the cases being in South Asia and sub-Saharan Africa, where the disease is more likely to be fatal (UNICEF-WHO, 2009). It has been also estimated that the great majority of acute diarrhoeal illnesses in children over the age of two years is attributable to bacterial pathogens (Carpenter, 1980). Amongst the various enteric bacterial pathogens, diarrheagenic strains of Escherichia coli are considerably responsible for causing bacterial diarrhea (Nataro and Kaper, 1998).
