The vulnerability of agriculture and livelihoods in the Member Countries of the Centre on Integrated Rural Development for Asia and the Pacific (CIRDAP) poses a significant threat to achieving climate- resilient rural development. CIRDAP includes 15 member countries: Afghanistan, Bangladesh, Fiji, India, Indonesia, Iran, Laos, Malaysia, Myanmar, Nepal, Pakistan, Philippines, Sri Lanka, Thailand, and Vietnam [CIRDAP, 2023]. ]. In many Asian countries, agriculture is still practiced using traditional methods that do not incorporate climate data or modern techniques. This reliance leads to several challenges, such as reduced productivity and crop diversity, increased vulnerability to weather fluctuations, and hindrance in establishing resilient value chains. For example, in Iran's rural sector, challenges such as centralized planning, patriarchal norms, inefficient extension systems, and weak inter-agency coordination are uniquely defining features (CIRDAP, 2025). However, evidence shows these challenges are widespread across the region:

1. Introduction
In recent decades, environmental contamination has emerged as a seriousthreat to our modern society. The relentless growth of urbanization andindustrialization leads to the ever-increasing production of hazardouschemicals. Safe disposal of these hazardous materials is crucial, as releasingthem into an already strained environment has severe consequences. Theexponential rise in human activity is directly related to the alarming risein local and global pollution levels, which severely disturbs the balance ofecosystems. Industrial activities, in particular, are a major source of highlyhazardous chemicals such as dyes, pigments, and aromatic compounds,which pose a serious threat to the environment. In India, the textile industry, amajor force driving the country’s economic growth, also ranks asthsecondlargestpolluter. The printing, finishing, and dyeing processes used in textileproduction generate significant waste (Dubey et al., 2018). Dyes, a majorsource of pollution in this industry, are syntheticand complex in structure. Thiscomplexity makes them poorly soluble in water, hindering biodegradation andposing a long-term environmental concern. The global textile industry utilizesa wide range of dyes, with estimates indicating over 100,000 commerciallyavailable options. The worldwide production of these dyes is estimated to be700,000 tons per year (Al-Tohamy et al., 2020). However, dye contaminationis a major challenge in this industry. Studies indicate that during synthesisand dyeing processes, a significant portion, ranging from 10% to 15% of thetotal dyestuffs used ends up released into global water bodies (Leal et al.,2020). A significant portion of textile dyes, ranging from 2% to 20%, aredirectly released into water reservoirs through wastewater effluents. This is

HYPERTHERMIA Hyperthermia is a condition characterized by elevated body temperature due to increased heat production or absorption, or reduced heat loss   owing to physical cause. Etiology • Physical causes such as exposure to high environmental temperature, severe and prolonged physical activity especially in hot humid condition or    animals    confined    with    poor    ventilation. • Spontaneous hemorrhage in hypothalamus can cause neurogenic hyperthermia. • Severe dehydration affects the heat loss by evaporation and thus can lead to hyperthermia. • Too much muscular activity.

Intelligent healthcare is advancing through the integration of multimodal data, trustworthy AI, federated learning, digital twins, IoT devices and real-time decision-support systems. This chapter reviews the evolution of healthcare-data analysis and examines emerging methods for intelligent diagnosis and predictive care. It discusses explainability, privacy-preserving analytics, interoperability, data governance and ethical frameworks necessary for responsible implementation. Wearable technologies and connected sensors support continuous monitoring, while human–AI collaboration improves clinical decision-making. Case studies illustrate practical healthcare applications and implementation strategies. The chapter also considers global-health requirements, particularly in developing countries, and identifies future opportunities for scalable, equitable, secure and clinically effective intelligent healthcare systems.

Curriculum development and lesson planning are complex educational processes requiring alignment among learning objectives, competencies, instructional activities, assessment strategies, learner characteristics, and changing societal requirements. Generative AI offers new opportunities to support educators and curriculum designers in managing these processes more efficiently and intelligently. This chapter examines AI-augmented approaches to curriculum development and lesson planning, with emphasis on personalization, competency-based education, adaptive learning, and data-informed instructional design. Generative AI can assist in developing learning objectives, lesson sequences, teaching activities, question banks, assessment rubrics, case studies, and differentiated learning resources. It can also analyze student performance and recommend modifications to curriculum content, learning pathways, and instructional strategies. The chapter considers applications within Indian educational contexts, including curriculum alignment, digital platforms, low-bandwidth environments, and emerging institutional initiatives. It also discusses challenges such as teacher resistance, inadequate AI literacy, interoperability, infrastructure limitations, data privacy, and ethical concerns. Successful implementation requires human review and pedagogical judgment. The chapter ultimately presents AI as a curriculum co-design and teacher-augmentation tool capable of improving efficiency, personalization, scalability, and educational relevance.

We all are familiar with the word “quality”. If we bring some fruits or vegetables from the market, the other family members will reflect on their quality by making observations such as: fresh or stale, good or bad quality or inferior product, etc. These observations are perceptions of consumers based on the sensory attributes of the fruit or vegetable colour, appearance, touch, smell or taste.

The quality characteristics of food that are acceptable to consumers are comprehended under the term “Food Quality. It includes external factors such as appearance (size, shape, colour, gloss, and consistency); internal factors (chemical, physical, microbiological) and characteristics/ specifications prescribed under the Government laws/standards. If consumer’s perceptions regarding quality of food are not positive he or she either will not purchase the material or will be paying less compared to when the consumer has positive perception about the quality.

The relationship between quality, profitability and market share has been well established. In the quest of quality, the dairy business is passing through revolutionary changes and the need for such changes has been very well realized. The leaders have initiated the process of setting vision and are working hard to provide the basic infrastructure with necessary resources. This has become a point of vital importance as the nation has now captured the first rank in milk production globally and is now ready and set to march ahead in the global race for dairy products market. Our country has great potential to export the dairy products such as cheese particularly Mozzarella, Feta, and indigenous products such as ghee, khoa, chhana, paneer, and array of sweets. Food items or dairy products to be traded in the international markets should be manufactured in accordance with global accepted norms and standards. In order to improve the quality of milk and milk products the Government of India is focusing on “Clean Milk Production”. As a dairy technologists and entrepreneurs, we must ensure production of quality products.

1. Country Background

India is one of the oldest civilisations in the world with rich cultural heritage. India has become self-sufficient in agricultural production, and is now the tenth industrialised country in the world. It covers an area of 32,87,263 sq km. Lying entirely in the northern hemisphere, the mainland extends between latitudes 8°4' and 37°6' north, longitudes 68°7' and 97°25' east, and measures about 3,214 km from north to south between the extreme latitudes and about 2,933 km from east to west between the extreme longitudes. 
Agriculture is the mainstay of the Indian economy, as it constitutes the backbone of the rural livelihood security system. It is the core of planned economic development in India, as the trickle-down effect of agriculture is significant in reducing poverty and regional inequality in the country. Growth in agriculture has a maximum cascading impact on other sectors, leading to the spread of benefits over the entire economy and the largest segment of population. 141 million hectares is the net sown area, while 190 million hectares is the gross cropped area. The net irrigated area is 57 million hectares with a cropping intensity of 134 per cent. Eighty-two per cent of farmers have small and marginal land holdings.

Multipurpose trees and shrubs are defined as all woody perennials that are purposefully grown to provide more than one significant contribution to the production and/or service functions of a land-use system that they occupy. In agroforestry systems, different species of trees and shrubs can be planted with many types of crops in a variety of patterns. Thus, it is required to know about the methods of propagation and nursery raising, planting and other silvicultural management practices along with the diverse uses of multipurpose trees and shrubs of tropical and subtropical areas before their selection for forestry and agroforestry activities. It is important to select the most suitable tree species since it is not easy to replace them once they have been planted.

Mangium (Acacia Mangium)

Acacia mangium is a single-stemmed evergreen tree that grows to 25-35 m in height and up to 60 cm in diameter. The bole is usually straight, often fluted near the base, free of branches for up to half its height. Mangium is native to Australia, Indonesia and Papua New Guinea. However, it tolerates varied site conditions and has adaptability to different planting objectives. Mangium shows most vigorous growth on well-drained, fertile soils in high rainfall areas in the humid tropics. It is valued for its rapid growth and has been planted throughout the humid tropics and is a major plantation species in the Asia Pacific. Provenances from Papua New Guinea consistently show better growth in height and diameter.

The transition from vegetative to floral meristems in higher plants is programmed by the coincidence of internal and environmental signals. The timing of floral transition has a direct impact on reproductive success. One of the most important environmental factors that affect the transition is the change in day length (photoperiod). Classical experiments imply that plants monitor photoperiods in the leaf and transmit that information coded within an elusive signal dubbed florigen to the apex to reprogram development. Recent advances in Arabidopsis research indicate that the core of the day-length measurement mechanism lies in the circadian regulation of CONSTANS (CO) expression and the subsequent photoperiodic induction of the expression of FLOWERING LOCUS T (FT) gene, which might encode a major component of florigen. The florigen paradigm was conceived in photoperiod-sensitive plants; nevertheless, it implies that although it is activated by different stimuli in different flowering systems but the signal is common to all plants. Flowering time, the major regulatory transition of plant sequential development, is modulated by multiple endogenous and environmental factors.

1. Pesticides

A pesticideis defined as anysubstance intended for preventing, destroying, attracting, repelling or controlling pests including unwanted species of plant, or animals duringthe production, storage,transportation, distributionand processing of the food, agricultural commodities or animal's feed or which may be administered to the animals for the control of ectoparasites. Pesticides include insecticides, herbicides, fungicides, acaricides, nematicides, etc.

According to food and agricultural organization (FAO) 1986, the term pesticidehas been defined as“any substance or mixture of substances intended for preventing or controlling any pest and includes anysubstance or mixture of substances intended for use as plant growth regulator (PGR), defoliant or desiccant. The term excludes fertilizers and antibiotics or other chemicals administered to animals to stimulate their growth or to modify their reproductive behaviour”. Pesticides are the largest group of poisonous substances that are widely broadcast today.

A number of insects infest seeds in storage. These insects infest seeds to fulfill their feed and shelter requirements, which result into qualitative as well as quantitative loss of seeds. Indian climate is very favourable for their multiplication and growth throughout the year. Storage pests move along with commercial products from one area to another and even to different countries in the world. Some adult insects are strong fliers and may spread from one to another place of storage or from source of infestation. Generally, all insects infesting seeds in storage belongs to insect order Coleoptera and Lepidoptera (Table 4.1). Some minor species belong to Pscoptera. These pests cause losses to man by destroying large quantities of grain, corn, legumes (beans, lentils and peas), milled cereal products, flour, bran, macaroni and other paste products, dried fruits, dried vegetables, cheese, nuts, candy and other food materials. They contaminate and thus eliminate for human consumption, far more food than they eat and either cause direct loss or transmit diseases to man and his domestic animals. These insects can be categorized as major or minor pests according to the loss of seeds caused by them. Similarly, on the basis of their feeding behavior, they can be grouped as follows:

Introduction to Molecular Biology Techniques Molecular biology is the domain of biology concerned with DNA replication, RNA synthesis (transcription), translation, and the role of proteins in cellular function, while molecular biology techniques are the keystones of modern biology, facilitating scientists to decode these molecular foundations of life. These molecular techniques aim to analyze and understand the structure, function, and interactions of biomolecules such as DNA, RNA, and proteins. These techniques facilitate an understanding of complex life processes such as gene expression, genetic variations, and cellular mechanisms. Researchers have used these molecular tools to unravel complex biological processes from genetic inheritance to cellular signaling pathways. The knowledge gained has been applied to solve challenges in various domains of biological science such as medicine, agriculture, and environmental science. During 1960’s methods to identify, isolate and manipulate molecular components were developed by molecular biologists. The field of molecular biology emerged in mid 20th century, driven by groundbreaking discoveries such as the deduction of the double-helix of DNA

Designing an earthen dam requires the coordinated evaluation of catchment runoff, reservoir capacity, site conditions, foundation properties, expected service life, and the consequences of failure. A selected return period is used to estimate extreme rainfall and runoff, while adequate spillway capacity and freeboard protect the embankment against overtopping. The dam must possess low permeability, stable upstream and downstream slopes, and sufficient resistance to seepage, settlement, erosion, and earthquake forces. This chapter presents design criteria, top width, dam height, side slopes, freeboard, seepage-control components, slope-protection measures, and stability considerations. It also explains procedures needed to create a safe, economical, and functional embankment.

Computational crop-disease detection uses machine learning, neural networks and image-processing techniques to provide timely and accurate diagnoses. This chapter presents a complete framework covering agricultural intelligence, disease categories, image acquisition, preprocessing, model training and classification. It examines datasets collected in fields or through drones and considers deployment through mobile devices, cloud platforms and other digital systems. Evaluation measures are introduced for assessing model accuracy and reliability. The chapter also considers limitations caused by insufficient or poor-quality data and variation in field conditions. Future directions include multimodal data integration and explainable models that provide transparent recommendations for sustainable crop protection and improved food security.

Introduction

Barley is an important cereal crop grown all over the world and is used mainly for feed and malt purposes and little for human food. Barley is the world’s oldest grain, as evidenced by discoveries in ancient cities in the Middle East and North Africa. It has been cultivated for about 8,000 years, and today is the world’s fourth largest cereal crop. Considerable evidence is available that points to the role of barley as sustaining food source in the evolution of humans. Additionally, alcoholic beverages of various types and fermented foods prepared from barley are commonly referred to in the ancient literature. As other food crops (wheat, rice, corn and rye) became more abundant, barley was relegated to the status of “poor man’s bread”. In the United states, barley used as food is 1.5%, as animal feed 65% and in malt and alcohol production 30% (Newman and Newman, 2006). In 1991, barley used as food in European countries was even lower (0.3%) than the United States. In contrast, during the same time period food was the largest for barley in Morocco (61%), China (62%), India (73%), and Ethiopia (79%). However, current consumer interest in nutrition and human health may help restore barley’s status in the human diet. Nutritional qualities of barley have been known since ancient times. For example, Ajgaonkar 1972 described how ancient Indian physicians effectively stabilized type II diabetics some 2400 years ago. Treatment was remarkable simple and not really different from recommendations that are given to diabetic patients today, i.e., lose weight, change diet, and increase exercise.

Introduction

Rice is grown in more than 100 countries in the world and is an important crop for nutritional security of large part of the population. World rice production in 2007 was approximately 645 million tones. Around 50 countries have an annual production of more than 1 million tones. Ninety percent of the total rice is produced in Asian countries, with two countries, China and India, growing more than half the total crop. Top ten rice producing countries are China, India, Indonesia, Bangladesh, Vietnam, Thailand, Myanmar, Japan, Philippines, and Brazil. In Bangladesh, Cambodia, Indonesia, Lao PDR, Myanmar, Thailand, and Vietnam, rice provides 50-80% of the total calories consumed. Major part of the rice is consumed locally where produced and only 6-7% of world rice production is traded internationally.

2.1. GERMPLASM COLLECTION
a. Propagation techniques
There are four main propagation techniques that are used in plant reproduction for most plants, viz;
• Seed
• Cuttings
• Marcotting
• Grafting
Note: That not all plants can be propagated by all the four methods mention above.

12.1 Introduction

Rainfall is the major source of water that contributes lion’s share for irrigation to crops. Before it reaches the earth, it is to a great extent pure in nature. By the time it falls on the ground surface, it comes in contact with various types of gases and suspended materials of the atmosphere and also after it flows as runoff on the surface it gets dissolved with many types of salts, impurities etc. that render the water to be impure. Many a time the industrial waste, agricultural wastes, pesticides, fungicides, chemical fertilizers etc. get mixed with water and make it unsuitable for irrigation use. Water being a universal solvent, it dissolves all most all organic impurities, salts etc. which makes it objectionable for both domestic and agricultural uses.

Irrigated agriculture is dependent on an adequate water supply of usable quality. In the past, water quality concerns were neglected because good quality water supplies were plentiful and readily available. This situation is now changing in many areas. Especially, in the arid and semi-arid zones, water quality is fast deteriorating which is posing threat to irrigated agriculture.

Conceptually, water quality refers to the characteristics of a water supply that will influence its suitability for a specific use. On the other hand, it refers to the situation of how well the quality meets the needs of the user. There are three quality indicators. They are physical, chemical and biological indicators. Even a personal preference such as taste is a simple evaluation of acceptability. For example, if two drinking waters of equally good quality are available, people may express a preference for one supply rather than the other; the better tasting water becomes the preferred supply. In irrigated agriculture, emphasis is placed on the chemical and physical indicators of the water and rarely the biological indicator is considered important.

Introduction

One of the triumphs of modern agriculture is the increase achieved in the productiveness of land, measured by yield of crops per hectare or per acre. This has enabled the earth to support a much greater population than would have been possible in past centuries. The increased productivity of the land is a result of scientific and technological progress in plant breeding, in control of pests and weeds, in irrigation and in fertilizers to supplement natural reserves of plant foods. But this progress makes it more difficult to fulfill one specific requirement of many crops: pollination. Pollination of flowers is an essential step in the sexual reproduction of angiosperms. Most angiosperm species rely on insects or other animals, rather than wind, for transfer of pollen among individual plants. The pollinators in turn benefit by obtaining floral resources such as nectar or pollen. Pollination is not only mutually beneficial to the interacting plants and animals, but also serves humanity directly through the yield of many crops, and indirectly by contributing to the healthy functioning of unmanaged terrestrial ecosystems (Costanza et al.,1997; Nabhan and Buchmann, 1997; Klein et al., 2007; Abrol, 2007 and 2008).

Introduction

Globally, India takes pride of being one of the world’s largest producers of horticultural and agricultural commodities. The rapid increase in the area under intensive cultivation of crops, introduction of high yielding varieties, lack of natural enemy load of the pests and changing climatic conditions is largely responsible for the severe pest depredations. Pest management in agriculture is a challenging task in the context of increasing agricultural productivity without upsetting the ecological balance and deteriorating the environment. Use of agrochemicals in agriculture though played a significant role to boost the agricultural production is posing enormous problems like environmental pollution, pest resistance, pest resurgence, toxicity hazards, secondary pest outbreaks, residues in feeds, foods, soil and water, destruction of biodiversity of useful natural enemies and some social economic and political problems. In response, there has been increased demand for alternative and selective pest control agents. Biopesticides are advantageous due to their target specificity, eco-safety, no development of resistance, reduced number of applications, yield and quality improvement, higher acceptability and value of produce for exports and suitability for rural areas.

Introduction

The method of obtaining the data for each and every unit belonging to the population or universe, which is the aggregate of all units of a given type under consideration, is known as complete enumeration survey or complete census. Examples of units are family, a period of time such as an hour, day, fishing village, fishing household, fishing establishment, fishing boat, fish landing centres etc. The type of unit to be considered would depend on the purpose of the view. The population may be finite or infinite. It is obvious that for any statistical investigation complete enumeration of the population is rather impracticable. For example, if we want to have an idea of the total catch of fish (monthly) in India, we will have to enumerate all the fishers who catch fish in the country, which is rather a very difficult task. If the population is infinite, complete enumeration is not possible. In addition, if the units are destroyed in the course of inspection, 100% inspection though possible, is not at all desirable. However, even if the population is finite or the inspection is not destructive, complete enumeration is not taken because it is time-consuming, expensive, and as well as it needs a large amount of resources in terms of trained personnel.

Cable conveyor: A power conveyor in which a trolley runs on a flexible, torque transmitting cable that has helical threads.

Cable: 1. A general term applied to rope or chain used for engineering purposes. 2. The standard wire with insulating cover used for conducting electrical current.

Cage harrow: A rolling harrow with horizontal shafts each fitted with star shaped tines joined by rods forming the lines of cylinder.

Estimates of heritability use statistical analyses to help to identify the causes of differences between individuals. Because heritability is concerned with variance, it is necessarily an account of the differences between individuals in a population. Heritability can be univariate–examining a single trait – or multivariate – examining the genetic and environmental associations between multiple traits at once. This allows a test of the genetic overlap between different phenotypes: for instance hair colour and eye colour. Environment and genetics may also interact, and heritability analyses can test for and examine these interactions (GxE models).

Introduction

India is the largest producer of vegetables in the world after China, contributes over 13% to world vegetable production and occupies first position in the production of cauliflower, second in onion and third in cabbage. Amongst vegetables, India is the largest producer of Ginger and Okra and ranks second in Potatoes production (10%), Onions, Cauliflowers, Brinjal, and Cabbages, etc. During 2012-13, India exported vegetables worth  1516.33 crores. The average productivity of vegetables in the country is 17.61 t/ha.

Prices of major spices such as chillies, jeera, turmeric and cardamom are being driven to the ground by higher production, poor export earnings and a lack of working capital with traders to hold the stocks. Last December, all these spices were at record highs. With the prices ruling high last year, the acreage of most of the spices has increased this year, indicating excess production. The chilli acreage has increased by 15% to 20% while the land under jeera crop is estimated to have gone up by over 26%. The turmeric production is heading for a historic high of 82 lakh bags (each bag of 70 kg) and cardamom is having a bumper harvest.

The relationship between man and plant resources of his surroundings is intimate. Of the 350 tribes inhabiting different parts of India, about 171 dwell in Himalayan region. The inhabitants of the mountain areas use native flora for food, fodder, fiber, fuel, timber and for health care of both human beings and their livestock. These plant resources, particularly medicinal and aromatic plants (MAPs), not only meet their health care needs but also support their livelihood. Recently the demand of MAPs has transformed from local and traditional needs to global needs. This has adversely affected availability and quality of raw material as also livelihood and health options of the local people. Most of the raw materials are gathered from the forests, and only a few plants are under cultivation. To avoid rampant exploitation of MAPs from nature, there is an urgent need to establish procedures for their cultivation and organized marketing. The present article deals with strategies and actions to protect livelihood options of the indigenous communities inhabiting mountain areas in western Himalaya as well as promote sustainable utilization of MAPs through scientific and technological interventions.

Introduction

India and China are two major Medicinal and Aromatic Plants (MAPs) producing countries, providing 40% of the global diversity and availability of rare species. The Ministry of Environment and Forests, Government of India has identified and documented over 9,000 species of medicinal plants that are significant for the pharmaceutical industry (AICRPE 1996). Of these, 2,000 to 2,300 species are used in traditional medicines while at least 150 species are used commercially on a large scale (EXIM Bank 1997).

11.1 Introduction

Tropical Root and Tuber Crops serve as primary or secondary staple to meet the calorie needs of one fifth of world’s population. These crops have myriad and complex roles to play in the food security and reduction of hunger and elimination of poverty. The starch content, pharmaceutical and nutraceutical value endow these crops with an extra ordinary range of potential and uses. Root and tuber crops are also greater sources of industrial raw materials for biodiesel and starch derived materials.

Saccharides : A monosaccharide sugar or combination of sugars is called saccharides.

Saccharification : The process of breaking a complex carbohydrate (starch or cellulose) into its monosaccharide components is called saccharification.

Saccharimeter : A device (polarimeter) used for measuring the amount of sugar in a solution is called saccharimeter. It is also known as saccharometer. It is a hydrometer with a special scale.

Arecanut palm (Areca catechu L.) is the source of common masticatory nut, popularly known as arecanut, betelnut, or supari. It is used extensively in India by all sections of people as masticatory, and is an essential requisite for several religious and social ceremonies.

Cashew (Anacardium occidentale L.) is an export-oriented crop grown for its nuts, a true drupe. Often referred as ‘wonder nut’, it is highly delicious and nutritive. Its nutritional composition compares well with almond, hazel nut and walnut. It is a zero-cholesterol nut with high content of unsaturated fatty acids, proteins and carbohydrates with a right combination of amino acids, vitamins and minerals. Kernels extracted from nuts are often consumed as such or used in confectionery items and various kinds of dishes. Kernel oil of pale yellow colour is used in pharmaceutical and cosmetic industries. Cashew nut shell liquid (CNSL) extracted from its shell has many industrial applications - for making paints, resins, flame-retardants, etc. Testa covering the kernel, rich in tannin, can be an acceptable substitute for wattle bark tannin in leather industry. Cashew apple, the pseudo-fruit, is rich in vitamin C. It is used to cure scurvy, diarrhea, uterine complaints and dropsy.

Potato is one of the major non cereal food crops in the world and ranks fourth after rice, wheat and maize. Due to its high production potential per unit area and time, the crop has been recorded for sustaining millions of lives during the times of war and hunger. Native of South America, this crop was introduced into India in early seventieth century. Currently India ranks 3rd for area and 2nd for production in the world [AICRP (Potato) Bulletin No. 2]. Potato is generally grown as rabi crop during October to December in gangetic plains of India but in hills it is grown almost throughout the year as commercial cultivation. In some states like Karnataka, it is generally grown during kharif season.

4.1 Introduction and Measuring

A measure of central tendency exhibits only one of the important characteristics of distribution, namely they typical representative figure to the whole set of its values. This measure alone will not adequately describe a set of observation unless all the observations are alike. Moreover one cannot understand completely about the data set with a measure of central tendency.  Because in real practical situation there may exits a number of sets of observations (or different distributions) whose measures of central tendency are same but they may differ individually from each other in a number of ways.  In particular two sets of values have the same mean but whilst one set of data is grouped close to the mean the other one is more spread out.  The following examples will illustrate this view point clearly.

Carbohydrates are the most abundant biomolecules on earth. They occur in nature as glucose, starch and cellulose etc. Each year, photosynthesis converts more than 100 billion metric tonnes of carbon dioxide and water into starch, cellulose and other plant products. Carbohydrates are polyhydroxy aldehydes or ketones and their derivatives. They provide 4K calories of energy per gram. They promote utilization of lipids and reduce wastage of proteins. They are readily available in roots, tubers, cereal grains, sugarcane and sugar beet.

Enzymes are organic catalysts produced by living organisms. They make possible biochemical reactions. Hence they are called biocatalysts. They are mostly a specialized class of proteins. However, there are some non-protein enzymes like ribozymes, which are RNAses. Enzymes speed up reactions at ambient temperatures. This is in contrast to chemical reactions like saponification of lipids which take place when lipids are boiled for a few hours with concentrated alkali. Enzymes, namely, lipases, hydrolyze lipids at body temperatures in minutes. They are superior to chemical catalysts by a factor of 10⁷ to 10¹⁴ . An enzyme may be a simple protein or a complex protein. They are produced by cells and are mostly globular proteins. Each cell contains an estimated 3000 different enzymes.

Abstract

Nitrogen is the most essential nutrient for all plants and is also the major limiting factor in plant productivity. High yielding varieties of all crops are responsive to nitrogen but its ever-increasing use has shown detrimental impact on the environment along with extremely low use efficiency. Nitrogen use efficiency (NUE) in crop plants depends on various internal and external factors, which are dealt in detail. There has been a significant interest in genetic engineering of the crops to improve NUE. The use of biotechnological interventions by manipulating genes of the nitrogen utilization pathway to improve NUE has not been very successful. But transgenics/mutants with modified capacities for nitrate uptake, assimilation and remobilization have enhanced our understanding of the genetic control of NUE. In both cellular, and at whole plant level the mechanisms involved in N remobilization from the senescing organs towards the grain have recently gained importance but their understanding is still preliminary. Recent evidences have shown that grain filling during later stages of crop growth is supported by N recycling.

When you are assigned with your thesis problem or some problem is puzzling you, the first step is to search the related literature ; here the term literature is used not as it is used in humanities but this means the literature related to the research work published by the earlier scientists on the topic. The searching of literature is a most important and first step in conducting research on a particular topic. This not only acquaint you with the work of other scientists who tried to solve the problem but also confirms the possibility that previous scientists might have solved that problem and yours will be a repeat attempt ; in that case you may tackle other aspects of the problem, if at all they are existing and important in present circumstances.

Abstract

The substantial loss in the shielding ozone layer has resulted in an increase in the solar ultraviolet radiation (UVR) on the Earth’s surface, which is detrimental for all living organisms ranging from prokaryotes to eukaryotes, including humans. This has augmented the scientific concern and interest in searching for the photoprotective compounds from diverse organisms. Cyanobacteria, the primitive O2-evolving photosynthetic prokaryotes are solely dependent upon the solar radiation for their energy requirement and thereby have to always face the UV-B stress. UVR affects cyanobacteria either directly or indirectly by inducing oxidative stress. In response, they have evolved the capacity to synthesize, accumulate and metabolize a variety of UV-absorbing compounds such as, mycosporine-like amino acids (MAAs), scytonemin, carotenoids, biopterin glucoside, as a strategy to reduce the direct and indirect damaging effects of UVR.

Factors which influence the colonization and life cycle of VAM fungi have important bearing on the extent to which they may benefit their host. As we move closer to using mycorrhizal fungi to increase growth and productivity of different plant communities, a thorough understanding of the factors which influence their survival, germination, root colonization an d sporulation will be critical. Seasons, physico-chemical characters of the soil, agronomic practices, plant protection chemicals, pollutants and genotypic characters of the host may affect VAM fungi and their potentiality to colonize and provide benefit to the host. In view of this, the effect of such factors on the VA mycorrhizal symbiosis and its benefit to diverse plant communities has been extensively investigated worldover.

Levitical Law of Old Testament initially authorized meat animals for food of man who had to part the hoof and chew the cud. So man started eating the animals and their edible parts of animals who consume grass and other arable crops.  Examples were cattle, buffalo, sheep, goat, pigs, horses, deer, reindeer, yak, camel etc. Now poultry have become major meat producing species while rabbit, guinea pigs, various game animals and birds provides substantial meat. Advancement of knowledge on quality and safety enforced the man to evaluate and grade the live animals and carcasses for values decision in marketing.

Phosphorus is the second important key element after nitrogen as a mineral nutrient in terms of quantitative plant requirement (Donahue et al., 1990), which is required in optimum amount for proper growth of plants and soil micro-organisms. Being a constituent of ATP, it is involved in various processes such as cell division, energy transduction through photosynthesis and biological oxidations and uptakeof nutrients. The average soil contains 0.05% phosphorus, but only one tenth (1/10) of this is available to plants due to its poor solubility and chemical fixation in soil (Barber, 1984). About 98% of Indian soils have inadequate supply of available phosphorus (Ghosh and Hassan, 1979). A survey of Indian soils showed that out of 363 districts, only 2.2% were high, 51.5% medium and 46.3% were low in phosphorus content (Ghosh, 1982).

Effect of Air Pollutants on Plants
 
Elements of those air pollutants which accumulate in plants (S from SO2, heavy metals from anthropogenic emissions etc.) may be used for specific bio-indication of possible effects caused by these pollutants, and for mapping their spatial and temporal distribution. Measuring accumulated components in plants rather than directly in the environment, provides the dual advantages of an integrated rather than a momentary value, and of a biological content rather than a mere concentration (Stocker and Gluch, 1990).

Abstract

The objective of this chapter is to provide an overview of heat pump dryer (HPD) and recent developments in its applications for drying of agricultural and food products. The basics of heat pump dryer, classification, operating principle, configuration and control system have been presented for better understanding. Many researchers have concluded that HPDs use energy more efficiently than electrical dryers. The heat pump dryer is best suited for drying high value commodities such as fruits, vegetables, spices, condiments, herbs, medicinal and aromatic plants at near ambient temperature for producing better quality dehydrated product.

Abstract
 
Grains are usually harvested above 20% (wb) moisture level and they are prone to microbial attack at high moisture level. In order to avoid both qualitative and quantitative losses that arise from microbial growth, grains are usually dried to safe moisture level. The safe storage moisture content may vary from 8-16% (wb), depending upon the grain and climate type. Therefore, drying is a necessary step in preventing these losses. Drying also reduces the bulk weight of the materials, thus easing transportation and storage. Drying can occur in thin layer or in deep bed. Different drying theories are proposed to characterize these drying processes. Theoretical as well empirical drying equations have been developed.

Abstract

Inspired by the human eye to brain assessment process, computer vision technology has demonstrated its potential for monitoring and controlling of several operations in food industry. Computer vision technology is, therefore, applied extensively in food drying process for monitoring nutritional value and sensorial characteristics because of its promising characteristics such as reliable objectivity and repeatability. In this chapter, after providing a brief explanation of the computer vision technology and its prerequisites and principles, an example is given to elucidate how this technology is used for monitoring the visual attributes of foodstuffs during drying process. Overall, monitoring the visual properties of food products like size, shape, color, and texture in off-line mode are the most popular issues to fascinate researchers’ attention to apply the computer vision technology in food drying. Nevertheless, industrial applications of the computer vision technology for real-time monitoring and control of food drying facilities as final goals of its introduction in food drying industry seem to be limited. For future studies, it is suggested to apply this unique technology along with advanced soft computing methodologies for in-line monitoring and control of food drying process in order to achieve high quality dried products. Finally, outlooks and potential employment of this technology in food drying domain are discussed as well.

India is the seventh largest country in the world with 17 per cent of the world’s population and with a total geographical area of 329 Mha, extending from 8°4’ to 37°6’ in the North and 68°7’ to 97°25’ in the East. It is bounded by the World’s highest mountains- the Himalayas in the North and surrounded by the Arabian Sea, the Indian Ocean and the Bay of Bengal in the South. The Indian Coastline along the southern part of the Country is over 7500 km long. The Country includes vast plains like the Indo-Gangetic Plains, and the Central Deccan Plateau, bordered by the Western Ghats on either side in the West and the South. The biodiversity in the terrain leads to a wide variety of climatic conditions, ranging from tropical to temperate climates across the Western Ghats. These range from permanent snowfields to tropical coastlands; areas of virtual desert in the northwest to fertile intensively cultivated rice fields in the northeast. A large proportion of India’s population continues to live in rural areas and depends heavily on climate-sensitive sectors such as agriculture, fisheries, animal agriculture and forestry for its livelihood. Agriculture is the mainstay of Indian economy. The Indian climate is dominated by the great wind system called the Monsoons, on which the Indian agriculture is dependant. The southwest monsoon is critical to the kharif crop (first crop), which accounts for more than 50% of the foodgrains production and 65% of the oilseeds production in the Country. The inter-annual monsoon rainfall variability in India leads to large-scale droughts and floods, resulting in a major effect on Indian foodgrain production (Parthasarathy and Pant, 1985; Parthasarathy et al., 1992; Selvaraju, 2003; Kumar et al., 2004) and on the economy of the Country (Gadgil et al., 1999a; Kumar and Parikh, 2001). Climatic variability and occurrence of extreme events are major concerns for the Indian subcontinent as they are inbuilt features under the projected climate change scenario. All the projections on climate change are based up on the General Circulation Models (GCMs). All the models project increase in temperature over the Country under different GHG emission scenarios. Rainfall variability is felt in different sub-meteorological divisions across the Country. Though the GCMs have been successful in depicting the gross features of the observed large scale climatological features, there is large uncertainty associated with these projections on regional scale, since the GCMs are yet to realistically reproduce the observed features at regional scale, particularly over the monsoon region (Kumar, et al., 2002). Several downscaling approaches are being used to derive the regional features from large scale model simulations. Under the projected climate change scenario, India will be one of the Countries facing the adverse impacts of climate change as agriculture is the mainstay of people of India. Hence, understanding of rainfall and temperature variability across the Country deserves attention in the projected climate change scenario.

The global economy has adversely been affected to a considerable extent due to weather related disasters which are not uncommon in the recent past due to global warming and climate change. It is true in the case of the Indian economy too. The year 2010 was the warmest year ever recorded, followed by 2009 in India. The year 2015 was the warmest year globally. Model simulations indicate that a marked increase in rainfall and temperature over India would be seen during the current century. The maximum expected increase in rainfall is likely to be 10–30% over the Central India. Temperatures are likely to increase between 2 and 3^oC by the end of 2100 A.D. Greater number of high surges and increased occurrence of cyclones in post monsoon period along with increased maximum wind speed are also expected along the East Coast of the Country. As a result, the occurrence of floods and droughts, cold and heat waves adversely affected the foodgrains production to a large extent across the Country in one or other region as seen in 2014, 2012, 2009, 2004, 2002 and 1987. It is true in the case of plantation crops also, which are predominantly grown in the Humid Tropics like Kerala (8°15` N and 12°50`N latitudes and between 74°50`E and 77°30`E longitudes). As seen in previous chapters, summer drought and heavy rains including waterlogging during monsoon period is a threat to plantation crops production in the Humid Tropics to a considerable extent. Waterlogging and floods due to excess rains could be minimised by providing surface and subsurface drainage facilities in plantation gardens which will improve the soil health and nutritional status, in turn yields can be increased in plantation crops.

Abstract

Elaboration of mycotoxins by several moulds in different agricultural commodities has been reported to be widespread. The mycotoxins are reported to cause variety of health hazards in different animals including Chicks, cow, horse, rat, Mouse, pig, rabbit, dog, including man. More than 150 species of moulds are reported to elaborate chemically and biologically diverse toxic metabolites. These mycotoxins  are known to induce variety of diseases commonly known as mycotoxicoses.The fungi which elaborate mycotoxins are diverse belonging to different groups of fungi.Mycotoxigenicity of these moulds not only differ among different genera but also among different species.  Some fungi such as Aspergillus flavus, A. terreus, Penicillium griseofulvum, P.expansum, P.nordicum, P.verrucosum, Fusarium acuminatum, F.culmorum, F. graminearum, F.moniliforme, F.oxysporum, F.solani, F. tricinctum and Cheatomium globosum are known to produce more  one  type of mycotoxin which differ in their chemical structure and biological activity.
