Abstract: Genus Jasminum contains 90 species to be true in existence and use, range from landscape to hair adornments, and perfumes. It is native to Indo-Malayan region. Morphological variants from different species have been developed in different regions in India. Unfruitfulness, cross incompatibility, pollen and seed sterility, delicate flower parts, peak and active night flowering, endosperm antagonism often pose significant challenge to breeders. Genetic information and trait heritability is almost unknown for this crop. Phenotypic traits requiring future improvement include recurrent flowering for fresh flower market, high concrete recovery, biotic and abiotic stress tolerance. Future breeding and genetic studies are needed for further transform this crop.

Mungbean (Vigna radiata L Wilczek) is considered to be originated from Vigna sublobata. It is also known as green gram, an important short duration grain legume with wide adaptability, low input requirements, and the ability to improve soil fertility by fixing atmospheric nitrogen. Mungbean is well suited to a large number of cropping system and constitutes an important source of cereal based diets. Mungbean is used for different purpose. The major portion is utilized in making dal, curries, soup, sweets and snacks. The food values of mungbean lie in its high and easily digestible protein. Mungbean is grown throughout Asia, Australia, West Indies, South and North America, Tropical and subtropical Africa. However, India alone accounts for 65% of the world acreage and 54% of the world production. It is widely cultivated in India in different seasons; however, the maximum area is under kharif cultivation. Extremely plastic morphology, phenology and short maturity duration (60 days) makes the crop ideal as a catch crop, inter crop or relay cropping. It is grown as sole relay crop in rice fallows during rabi season in A.P., Tamilnadu, Karnataka and Orissa and sole catch crop during spring/summer season in Uttar Pradesh, Bihar, West Bengal, Jharkhand, Punjab, Haryana & Rajasthan (Table 1).

Chickpea, Cicer arietinum L, is the second most important pulse crop in the world. In India, it occupies prime position in terms of area, production and economic value and as an important constituent vegetarian diet. Chickpea is traditionally grown in many parts of the world covering Asia, Africa, Europe and North and South America. But the bulk of it is produced and consumed in South Asia and increasingly in Middle East as well as in some Mediterranean countries. Recently, chickpea cultivation started in Australia, Canada and USA mainly for export to south Asia. The cultivated species, Cicer arietinum L. (2n=16 and n=8), is characterized by possessing two distinct types-small and brown seeded known as desi type, and bold and white seeded known as kabuli type. The former is mostly cultivated in Indian sub-continent. Chickpea (Cicer arietinum L.) is also known by several common names viz., Bengal gram, Gram, Chhola, Hommes and Garbenzobean.

Chickpea provides 2-3 times more protein than many cereals, constituting a major component of the agrarian diet of the Indian sub-continent. Chickpea grains provide about 18-24% protein, 4-10% fat, 52-70.9% carbohydrate, 10-23% fibre, minerals and vitamins. Among essential amino acids lysine, methionine, threonine, valine, isolucine and leucine are major components of seed protein. It also contains considerable amount of vitamins such as B₁ and B₂, ascorbic acid (vitamin C) and niacin also. Chickpea, therefore, plays an important role in human nutrition.

13.1 INTRODUCTION

Weed is defined as an unwanted plant growing at a place where it is not desired. Weeds are unwanted and undeserved plants that interfere with the utilization of the land and water resources and thus adversely affect crop production and human welfare. Thus, a plant out of its place or a plant growing where it is not desired at that time is a weed. Weed has no species, but name was suggested as a useless and harmful plant that persistently grows where it is quite unwanted. According to Jethro Tull, the father of Weed Science, weed is defined as the unwanted, undesirable plant, growing out of their proper place, which interfere with the utilization of natural resources, prolific, persistent, competitive, harmful and even poisonous in nature and can grow in adverse climatic conditions. Of the total losses caused by pests, weeds have a major share (30%). They reduce the crop yield and decrease the quality of produce and hence reduce the market value of the turnout. Weeds are a major problem to horticultural production as they take advantage of their initial slow growth rate. Weeds reduce crop yield, lower their quality, act as alternate host of many pests/diseases and also have allelopathic effects on crops. Weeds also interfere with vital farm operations like weeding, fertilizer application, herbicide application and harvesting. Both annual and perennial weeds are common in their actions reducing the productivity of fruit trees. Weeds also provide shelter to various pathogens by becoming an alternate or collateral host of invaded crops by a number of fungal, bacterial and viral diseases.

The worst weeds found in the world are Cyperus rotundus, Cynodon dactylon, Echinochloa crusgalli, Echinochloa colona, Eleusine indica, Sorghum halepense, Imperata cylinderica, Eichhornia crassipes, Portulaca oleracia, Chenopodium album, Digitaria sanguinalis, Convolvulus arvensis, Avena fatua, Amaranthus hybridus, Amaranthus spinosus, Cyperus esculentus, Paspalum cojugatum, Rottboelia exaltata (Rana and Rana, 2016). All of these weeds are found in India. It has been reported that about 36-42% losses may occur due to inadequate management of weeds in apple (El- Metwally and Hafez, 2007). Therefore, management of weeds in all agro-ecosystems is crucial to sustain our crop productivity and to ensure the food security to the rapidly increasing population.

The major focus of the study was to critically analyse the overall performance of Women Dairy Cooperative Societies (WDCS) in two districts of Odisha. The methodology used in carrying out investigation has been outlined in eight sections as mentioned below.

Soil mechanics as a distinct branch of soil science is comparatively of recent growth. Its need arose from the fact that the requirements of the engineer are very often quite different from those of the agriculturist. Whereas the former would as a rule require hard, compact, impervious soil, the latter would have no use for it for the growth of his plants which require soft, friable and porous soil. The agriculturist generally has to look up to nature to help him out of his difficulties, the engineer has to depend on his scientific skill to modify the soil to suit his requirements. In this chapter an attempt will be made to explain in a simple language the requirements of the building, road, and irrigation engineer for particular types of soils and how they are met by modifying the soil if the required properties already do not exist.

Introduction

With growing concern about climate change, environmental sustainability, soil health and food safety, conservation agriculture, organic agriculture and protected cultivation are emerging production systems being popular in India. The changing farm practices in these production systems invite many biotic stresses and demand novel approaches for their sustainable management for profitable farming. The dynamics of biotic stresses vary from system to system; therefore they require system specific approaches for sustainable management. The different agronomic/ plant protection measures practiced in above mentioned emerging systems are listed in Table 1. Protected cultivation is meant for the high value crops are grown, the management of biotic stresses is the foremost important to minimize losses. Organic farming demands more preventive measures for sustainable control of biotic stresses rather than curative measures because of complete restriction on use of harmful chemical pesticides. Conservation agriculture demands more of ecofriendly measures for biotic stress management with minimal use of pesticides. In this chapter, we discussed novel approaches for biotic stress management in emerging production systems.

Fruit Juice Beverage: This is the fruit juice that has been considerably altered in composition by adding water, sugar, acid, flavour, colours, preservatives etc. before consumption. It may or may not be diluted before it is served as a drink eg. squashes, nectars, appetizers etc.

Biodiversity is a magnificent contribution of nature on our planet. The great variety of life forms on earth has catered for man’s needs over thousands of years. This diversity of living creatures which forms a support system has been used by each civilization for its growth and development. Those that used this “bounty of nature” carefully and sustainably survived. Those that overused or misused it disintegrated. The attempt to classify and categorize the variability existing in nature for over a century has led to an understanding of its organization into communities of plants and animals. This information has helped in utilizing the earth’s biological wealth for the benefit of humanity and has been integral to the process of development. This includes better health care, better crops and the use of these life forms a raw material for industrial growth which has led to a higher standard of living for the developed world. However, this has also produced the modern consumerist society, which has had a negative effect on the diversity of biological resources upon which it is based. The diversity of life on earth is so great that if we use it sustainably we can go on developing new products from biodiversity for many generations. This can only happen if we manage biodiversity as a precious resource and prevent the extinction of species.

The sustainable management of biodiversity is one of the most important challenges facing humanity. Biological diversity, abbreviated to biodiversity, refers to the variety of life forms at all levels of organization, from the molecular to the landscape level. These are the legacy of billions of years of evolution, shaped by natural processes and increasingly, by the activities of humans. Losing biodiversity has eroded the basis for social and ecological resilience, which has resulted in reducing the capacity for adaptive responses in a rapidly changing world. However, human activities still continue to have a large impact on the environment and on biodiversity. Agricultural, urban and infrastructural developments and climate change has exacerbated biodiversity loss. As a result, ecosystem functions and services are affected with serious consequences. The Sustainable Development Goal should be devoted to “protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss”. It is high time to realize the linkages between the severity of global biodiversity loss and degradation of ecosystems and the negative impact that this situation have resulted on food security, nutrition, access to water, health of the rural poor and people worldwide.

14.1. Introduction

Environmental pollution primarily deals with five types of pollution: soil pollution, water pollution, air pollution, sound pollution and light pollution. However, soil, water and air pollutions are considered very important as the pollutants from the environmental compartments may be cycled within themselves, enter the food web and interfere the biological processes adversely of any living species. Soil supplies nutrients and water to plants which, in turn, act as the nutrient supplier to animals and humans. Thus, maintenance of soil quality is considered prerequisite for growth of plants, animals and humans. If soil, water and air are polluted through various mechanisms, living components in the environment are suffered adversely. Soil, water and air pollutions are associated with the build-up of soil contaminants such as toxic organic and inorganic compounds, petroleum hydrocarbons, radioactive materials, salts, disease causing agents etc. above the permissible limit, so that their presence will cast adverse effects on physicochemical and biological properties of soil which in turn exert negative impact on crop growth and on any non-targeted organisms. Common soil contaminants include heavy metals, pesticides, petroleum hydrocarbons, fertilizers if used in excessive amount, and many others. Contamination of the soil, air and water results from intensification of farming activities. Primarily nutrients (particularly nitrogen and phosphorus), sediment, wastes, pesticides and salts are regarded as agricultural nonpoint source pollutant. Realistically, most of the pollutants originate from anthropogenic activities, although there exists many naturally occurring mineral components that may exhibit toxicity towards living system at higher concentration. Land disposal of municipal and industrial wastes, automobile emissions, mining activity, and application of fertilizers and pesticides to agricultural field cause a continuous accumulation of heavy metals and other pollutant components in soils. These pose threats of environmental degradation via soil erosion, loss of biodiversity, climate change etc.

Reproduction is essential for the survival of the species but not for the survival of the individual. The female reproductive system is entrusted with the responsibility to produce female gametes ie ova and hormones that regulate and integrate the functional activity of the female reproduction.

Liberalized economies and evolving businessstrategies push variousindustries to achieve a competitive edge both in the domestic and international markets. Food industry especially, works on the bedrock of quality of products and services in order to attract and retain customers. In this new world of economic order, customers can select from wide range of products and services that are available in the market.

Food safety is a discipline ensuring safe consumption of food without any injuries to human health. It is multifaceted and influenced by various factors including, food processing, handling and practices, consumer demand and their knowledge, globalization of world food trade, changes in food consumption pattern (Chen et al., 2020).

Breeding of Indian Major Carps (IMCs) and Minor Carps involves specific practices to induce spawning in these fish species. IMCs, like Catla, Rohu, and Mrigal, are typically bred during the monsoon season through induced breeding methods, which involve injecting hormones or chemicals to trigger spawning. Minor carps, while also bred during the rainy season, may have slightly different hormone injection dosages and breeding practices.
The carps are freshwater fishes which contribute about 85% of aquaculture production in India. It has the first position in global freshwater aquaculture production. Commonly cultivated carp varieties are catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus mrigala) which are of Indian origin and are collectively called as Indian Major Carps (IMC) which depends on different niches of a water body.

A drone is a sophisticated piece of technology made of many key components that work together to enable flight and various functions. The primary parts include the frame, which provides the structure and support for all other elements; the motors and propellers, which generate lift and control movement; the flight controller, acting as the brain of the drone, processing input from sensors and guiding the drone’s flight path; and the battery, which powers the system. Moreover, sensors like GPS, accelerometers, and gyroscopes are integral for stability and navigation. Many drones also feature cameras and other payloads for specific tasks, such as aerial photography, surveying, or surveillance. These components, working in harmony, allow the drone to perform a wide range of applications in industries like entertainment, agriculture, and delivery.
KEY COMPONENTS OF A DRONE
Agricultural drones consist of multiple components, including a remote controller, an aerial platform, and a spraying mechanism. They possess sensors, cameras, and more components to enhance crop management and productivity. Understanding the fundamental components is vital to understanding the potential of agricultural drones. This section delineates the essential components that render these drones viable instruments for contemporary agriculture.

INTRODUCTION
A produce packing plant is a specialized facility designed to sort, package, and sometimes store fresh produce. These facilities are essential in the agricultural supply chain, helping to maintain the quality, safety, and freshness of fruits and vegetables as they are prepared for distribution to retailers or consumers. Packing plants are commonly used in commercial agricultural operations, especially for fruits and vegetables grown in large quantities.
Uses and Managing a fruit and vegetable packing plant involves overseeing all activities related to the handling, grading, packaging, and storage of fresh produce, ensuring that it meets quality standards and is ready for distribution. Effective operations and management are essential to maintaining product quality, optimizing efficiency, and ensuring profitability for producers and suppliers. The operation includes several stages that require coordination, from the receipt of the harvested products until they are sent to markets or retailers. Management, on the other hand, refers to the processes, strategies and decisions that ensure the smooth operation of the packing plant.
Packing plants serve as a collection center for fruits and vegetables prior to their distribution and marketing. These can be simple packing sheds with limited equipment and minimal operations or a large, well-equipped complex with equipment for specialized operations. The types of operations performed vary depending on the different products and market demands. Products destined for export or supermarkets often undergo more elaborate operations than those in local markets. Some of these operations include the following:
OPERATION
The specific operations carried out in a packinghouse depend on the type of crop being processed and the target market. Some or all of the following steps may be involved:

Artificial Intelligence (AI) tools have rapidly transformed the way we work, learn, communicate, and solve problems in the 21st century. From automating routine tasks to assisting in complex decision-making, AI tools are becoming an essential part of modern life and professional environments. These tools use technologies such as machine learning, natural language processing, computer vision, and data analytics to perform tasks that traditionally required human intelligence. As a result, AI is not only increasing productivity but also changing the nature of work across industries. AI tools are software applications or platforms that use artificial intelligence to perform specific functions such as content creation, data analysis, customer support, language translation, image generation, video editing, coding assistance, and workflow automation. Today, AI tools are used in education, healthcare, business, marketing, finance, engineering, journalism, and many other fields. For example, students use AI tools for research, writing, and learning new concepts; businesses use AI for customer service chatbots, data insights, and marketing automation; and designers use AI for image and video creation.

River-training works guide and regulate the flow of a river to achieve a stable channel alignment, protect banks, improve navigation, prevent erosion, and reduce flood damage. Rivers naturally change their course through sediment deposition, bank cutting, meandering, and variations in discharge. Engineering interventions must therefore account for hydraulic forces, sediment movement, channel morphology, and long-term river behaviour. This chapter defines river training and explains its objectives, benefits, limitations, and key design principles. It discusses guide banks, groynes or spurs, embankments, revetments, pitching, launching aprons, cut-offs, and related protective works. It also considers structural placement, classification, construction materials, maintenance, and environmental consequences.

Flood routing predicts how a flood hydrograph changes as it passes through a river reach or reservoir. Storage, channel geometry, friction, inflow distribution, and outlet conditions generally reduce, delay, or otherwise modify the flood peak. Routing results help forecast downstream water levels, determine reservoir releases, design spillways and channels, issue warnings, and evaluate flood-control alternatives. This chapter introduces the continuity and storage principles underlying flood routing and distinguishes reservoir routing from channel routing. It discusses hydrologic and hydraulic approaches, including level-pool, Muskingum, and related techniques. Attention is also given to inflow and outflow hydrographs, routing coefficients, travel time, attenuation, data requirements, assumptions, calculations, and practical engineering applications.

Genetic improvement creates permanent, heritable gains in milk production, growth, fertility, disease resistance and environmental adaptation. This chapter explains how artificial intelligence complements conventional phenotypic and pedigree-based selection by analysing large genomic and performance datasets. Machine-learning models reveal genotype-phenotype relationships, predict breeding values and support earlier, more reliable selection. Applications include genomic selection, precision breeding, reproductive technologies, bioinformatics and digital twins. AI can reduce generation intervals and improve the efficiency of breeding programmes, but its success depends on data quality, representative populations and interpretable models. Ethical concerns, genetic diversity and long-term sustainability must also be considered when designing AI-supported breeding systems.

Microbiology is the scientific study of microorganisms, including bacteria, fungi, algae, protozoa and viruses, and their interactions with plants, animals and the environment. Microorganisms are microscopic in size but have enormous importance in agriculture, food production, environmental management and biotechnology. In agricultural systems, microorganisms contribute to decomposition of organic residues, nutrient cycling, soil fertility, plant growth and suppression of harmful organisms. Beneficial microorganisms also form associations with plant roots and improve nutrient availability and plant health. At the same time, certain microorganisms cause plant diseases, food spoilage and environmental contamination. Agricultural microbiology applies the principles of general microbiology to understand these beneficial and harmful activities in farming systems. This chapter introduces the scope and importance of microbiology, major groups of microorganisms, basic laboratory concepts and their applications in agriculture. An understanding of microbial structure, metabolism, diversity and ecological functions provides the foundation for studying soil microbiology, plant–microbe interactions, biotechnology and environmental remediation.

Soil health and nutrient availability are fundamental determinants of plant growth, crop productivity and sustainable agricultural production. This chapter examines how artificial intelligence can support soil health monitoring and nutrient management. It introduces soil health concepts and nutrient dynamics before exploring AI technologies capable of processing soil, environmental and crop-related datasets. AI-based approaches can assist in identifying soil conditions, assessing nutrient requirements and developing site-specific nutrient management strategies. Integration with precision agriculture technologies can improve fertilizer-use efficiency and reduce unnecessary inputs. The chapter also considers practical case studies, challenges and future opportunities. By combining AI with agricultural data, soil monitoring can become more timely, precise and useful for informed crop management.

Early and accurate detection of plant diseases is essential for protecting crop productivity and reducing agricultural losses. This chapter explores artificial intelligence-based plant disease detection using image processing and deep learning. It introduces major plant diseases and the fundamentals of image processing before examining deep learning approaches for identifying disease symptoms from plant images. AI models can automate disease recognition and support timely interventions in smart agricultural systems. The chapter presents a proposed methodology and discusses results and analysis, practical applications and limitations. It also considers challenges associated with data quality, environmental conditions and model performance, followed by future directions for developing more accurate, scalable and intelligent plant disease diagnostic systems

Metabolomic research depends on analytical technologies capable of detecting and characterizing large numbers of chemically diverse metabolites. This chapter introduces the principal analytical platforms used for metabolite analysis, with emphasis on mass spectrometry and nuclear magnetic resonance spectroscopy. Gas chromatography–mass spectrometry, liquid chromatography–mass spectrometry, capillary electrophoresis–mass spectrometry, and NMR are examined in relation to metabolite separation, identification, and quantification. The chapter also considers sample preparation, analytical workflows, advantages and limitations of different platforms, and complementary approaches for achieving broader metabolome coverage. These techniques provide the analytical foundation for metabolic profiling, biomarker discovery, pathway analysis, and systems-level biological investigations.

The Sun is the primary source of heat to the Earth and its atmosphere. The heat received from other celestial bodies as well as the interior of the Earth is rather too significant. The distance that separates the Earth from the Sun is about 149.0 million km. The diameter of the Sun measures roughly about 1.3824 million km. The surface temperature of the Sun is estimated between 5500^o C and 6100^o C. (or 5762^o K).

The weight of the sun is about 1.9 X 10 30kg. The radius is 6.97 X 10 8 m or the diameter of the sun is 14 X 10 5 km. The mass of the earth is 6 X 10 24 kg, the radius is 6.4 X 10 6 m. The gravitational force of the earth is 9.81m/s². Whereas the sun‘s attractive force is 274m/s². This is 25 times higher than earth’s gravitational force.

10.1 Normal Distribution
The normal distribution is the most widely used distribution in statistics. Almost all biological data including the agricultural data eg. crop yield, plant height, seed weight, seed size, protein percent in pulse, oil content in an oil seed etc are assumed to be normally distributed. In practice their distribution is rarely verified. In distribution theory, for large values of n, the number of trial (or sample size), almost all the distributions e.g. Binomial, poission, Negative binomial, chi square, student’s t, and Snedenor’s F distributions etc. are very closely approximated by normal distribution. It is a continuous distribution with mean and variance as its two parameters.

Introduction

For many years it has been an elusive task to provide a precise definition as to what constitutes quality in wheat. Each country has its own traditions in bread and other bakery products. Quality will mean different things to a miller, a baker, a grain handler or a plant breeder. As the baking industry becomes increasingly specialized, specific qualities are sought. Even among those wheat varieties generally recognized as having desirable quality traits, the influence of environment can be substantial, and this necessitates a high level of skill on the part of grain buyers to survey the current year’s crop and blend the wheat for a specific end-use. This genotype X environment effect on quality also limits the capacity of end-users to source identity-preserved wheat from a narrow geographic area. Those of us engaged in the field of plant breeding are concerned primarily with those traits that can be manipulated genetically, and we study their stability under a range of climatic conditions. Constraints in time, cost, and sample availability usually necessitate the use of predictive tests during early generations, followed by milling and baking tests on advanced lines that have met a number of agronomic, disease and predictive quality criteria.

Introduction

Dough is a complex mixture of flour constituents, water, salt and other ingredients depending upon the requirements of end-products. It is the principal intermediate stage in the transformation of wheat into different end-use products. Rheological properties of dough determine the behaviour of dough during mixing, rounding and molding used in making different products and also effect on the quality of finished product. Therefore, understanding the various features of dough rheology and their relations with product quality is important. The importance is enhanced further because of mechanization and automation of baking industry. Dough is composed of continuous phase in which gas cells are dispersed. The continuous phase is called “dough phase”. It consists of starch granules embedded in protein matrix along with some lipids, cell remnants and yeast cells in fermented dough. Gas production and retention is the most comprehensive quality requirements of the dough for bread making. The ability of the wheat dough to retain gas during fermentation and oven rise is unique. This depends on the ability of the dough to be stretched into thin membranes because of protein phase.

Introduction

Wheat is the most important cereal crop to the human kind. It is the main source of energy and nutrition in human diet. Wheat is consumed in the form of large number of end products as chapati, bread, biscuit, cakes, pretzels, noodles and pasta products. Millions of people are involved in milling, baking and pasta products industry with huge turnover per annum. However, each end-use product of wheat has it’s own specific requirement for example basically hard wheats along with strong gluten and high protein content are used for bead making. Soft wheat with weak gluten and low protein content are required for biscuit making Souza et al. (1994). Durum (tetraploid) wheat is used for pasta products as macaroni, vermicelli and spheghatti and Dicoccum for therapeautic purposes. Often chemical improvers are used to improve the dough properties for these products. Most of these chemicals have been banned because of their toxic effects. Therefore, only alternative is to develop varieties suited to meet the requirements of these end-use products. This needs better understanding of molecular basis of grain quality to accelerate breeding for producing wheat varieties for each end-use product separately. Storage proteins are the major component of grain which determines end-product quality. In this chapter detailed structure, genetics and functionality of gluten proteins are described.

INTRODUCTION

Himachal Pradesh, the mountainous state is well known for its natural wealth. It is situated between 300 22’ 40"to 330 12’ 40" N latitude and 750 45’ 55" to 790 04’ 20" E longitude in the western Himalayas. The 12 districts viz., Bilaspur, Chamba, Hamirpur, Kangra, Kinnaur, Kullu, Lahaul & Spiti, Mandi, Sirmaur, Shimla, Solan, and Una of the state covered 10.5 per cent of the Indian Himalayan Region (IHR) and 1.69 per cent of country’s geographic area. State experienced high variation in an elevation and climatic conditions. An elevation of the stateranged from 350 to 6975 metres above mean sea level (amsl.) that increases from west to east and south to north.On the basis of elevation and slope,the state is divided into fourdistinct topographical regions: (1) Shiwalik Hills, (2) Mountains-Lesser Himalaya, Greater Himalaya and Trans Himalaya, (3) Valleys-Shiwalik dun valleys, fluvial, and glacio-fluvial valleys, and (4) Mountain Passes (Singh and Kumar, 2014). Whereas, physiographically, state is divided into four agro-ecological zones: the Shivaliks’ low, mid and high-hills; and the cold and dry or the alpine zone (Table 1). The 70% of the state area is steep to very steep, about 19% is moderate to moderately steep, and 11% is gentle to nearly level slopes.

INTRODUCTION
 
A single teaspoon of soil has more organisms than the total number of people in this planet. Therefore measuring microbial population and their activity in soil is essential in order to measure the potential of a soil to mineralize nutrients. The rhizosphere is the biologically active zone of soil, where plant roots and microorganisms interact, and is of significant importance for plant performance as well as for nutrient cycling and ecosystem functioning (Singh et al. 2004; Marschner et al. 2004., Bhaduri et al. 2015). The structure of rhizosphere microbial communities is the result of complex interactions between plant genotype and fertilization (Aira et al. 2010).

3.0 INTRODUCTION

There are two main types of plant reproduction / multiplication that are used and these include sexual reproduction known as seed propagation / multiplication and the asexual reproduction known as vegetative propagation / multiplication. Propagation is most often by seeds produced by plants or by plant parts like vines, roots, tubers, suckers, etc. Propagation is the natural mechanism by which plants regenerate. Seed is the organ of reproduction in flowering plants.

3.1 SEXUAL REPRODUCTION OR SEED PROPAGATION TECHNIQUES

Seed is the organ of reproduction in flowering plants. Sexual reproduction is propagation by seeds. This is the main method by which plants reproduced in nature as most plants produce seeds except in species that have separate male and female plants; e.g. Njansang (Ricinodendron heudelotii) and Black fruit (Canarium schweinfurthii)

Seed multiplication seems to be the most practicable technique by the farmers. Example Agroforestry Species that are mostly propagated by seeds are Sweet Bush mango [Irvingia garbonensis], Bitter Bush mango [Irvingia wombolo], Bitter kola, Kola nitida, Kola acuminata, Njansang [Ricinodendron heudelotii].

2.1 Introduction

Rain and snow are the two chief sources of water of the earth. In-situ conservation of rainwater helps the plants to meet some of their consumptive uses directly. Not all the amount of rainwater that falls at a point is conserved by the soil reservoir to support the plant growth. Some part of it flows over the soil surface as surface runoff and some seeps down as infiltration and finally adds to the under ground reservoir. Therefore, rain or snow, which is not used directly by the plants, becomes a potential source of either surface or ground water for irrigation. In areas with extreme low temperature, snow contributes major source of water supply wherever, in humid and sub humid regions, rain is the principal source. Precipitation, rain or snow, is the first stage of the continual cycle of water in its round from atmosphere to the earth and return by evaporation from water bodies, snow surfaces and land surfaces. The continual cycle of distribution of water is governed by the process called as hydrologic cycle. Thus, precipitation or atmospheric water is the first form of water above the earth’s surface, the second form being the surface water on earth and the third form is the subsurface water or underground water. The study of occurrence, distribution and circulation of precipitation through the unending hydrologic cycle forms the basic part of study of hydrology. As mentioned above, the part of precipitation that is not used by the plants in-situ flows over the soil surface as runoff and contributes to either surface or ground water supply.

11.1 Introduction

The entire amount of water that is diverted at the canal head regulator does not reach at the field for use of irrigation. Major amount of it is lost on way during its movement in the canal systems. During the passage of water from main canal to outlet at the head of the water course, water may be lost either by evaporation from the surface or by seepage through the peripheries of the channel. These losses are sometimes very high, and may go up to 50 % of the total water diverted into the main canal. Evaporation losses are low and may go to a maximum of about 7 percent.of total losses. The major loss of water in the conveyance system is the seepage loss. Seepage loss depends on the channel geometry and evaporation loss is proportional to the area of free surface. In determining the designed channel capacity, a provision of these water losses must be made. The provision for the water lost in the watercourses and in the field however, already made in the outlet discharge factor, and hence no extra provision is made on that account. However, excluding the above two losses, there is operational loss which when added to the evaporation and seepage losses, the total losses goes up the maximum 50 percent level. The operational loss includes spillage, over-toping, leakage through rodent holes, dead storage, initial infiltration and evapotranspiration from the vegetation along the watercourse. Evaporation and seepage losses of the canals are discussed below.

Introduction

The competition between human and livestock population for the existing animal and plant resources has been of great concern to the poultry nutritionists. Today the poultry industry has already challenged by the high price of the feed ingredients. Moreover in the next century there will be a shortage of conventional feed stuffs for use in poultry production. Efforts are on to look forward for the new feed resources and to evaluate them for their inclusion in the poultry ration. However many of the feed stuffs are characterized by the presence of certain incriminating factors. The incorporation of feed stuffs containing incriminating factors may adversely affect the performance of poultry. The nutritional strategy involving the use of feed enzymes offer immense potential to overcome the problems. The use of enzymes in feed mixtures of growing poultry particularly for young chicks has been the subject of much research activity in the recent decades. The interest in the feed enzymes is a reflection in changing the attitude of the society and the economic climate of the feed industry. It has been seen that approximately 187 million metric tons of cereal grains (FAO, 2011) and 26.02 million tons oil seeds as per the trade estimate for 2011-12 are produced in India which yield non starch polysaccharides (NSP) as a part of variety of products.

Introduction

The term “probiotic” is derived from Greek and means pro: for and bios: life (for life) in contradiction to antibiotic which means: against life. The term probiotic was first introduced by Lilly and Stillwel (1965) to describe growth-promoting factors produced by microorganisms. Parker (1974) first specified designation “probiotic”. He defined probiotics as microorganisms or substances, which contribute to the balance of the intestinal micro flora. Crawford (1979) defined probiotics as a culture of specific living microorganisms, primarily Lactobacillus spp. that are implanted in the organism and ensure the rapid and effective establishment of a beneficial intestinal population. Fuller (1989) discussed the definition given by Parker (1974) and considered it too broad, as cultures, cells, and metabolites are also included in antibiotic preparations. He redefined “probiotic” as a live microbial feed additive, which beneficially affects the animal by improving its microbial balance. Havenaar et al. (1992) pointed out that the definition of “probiotic” made by Fuller (1989) was restricted to feed supplements, animals, and their intestinal tract. Therefore, they generalized Fuller’s definition of “probiotic” as a mono or mixed culture of living microorganisms, which beneficially affect the host by improving the properties of the indigenous micro-flora. Through 1989, United States Department of Agriculture (USDA) advised manufactures to use the term: “direct-fed microbial” (DFM) instead of “probiotic” (Miles and Bootwalla, 1991). The USFDA defined DFM as a source of live naturally occurring microorganisms, including bacteria, fungi, and yeast. Vanbelle et al. (1990) pointed out that most researchers considered “probiotic” for selected and concentrated viable counts of lactic acid bacteria. Koh et al. (1992) pointed out that as a biological product for newly hatched chicks a bacterial culture producing acetic acid could be used. Such a culture might be supplied to the chicks either through their drinking water or by the feed. For controlling the biological balance in the chicken’s intestinal tract different probiotics may be used. The US National Food Ingredient Association presented, probiotics (direct fed microbial) as a source of live naturally occurring microorganisms and this includes bacteria, fungi and yeast (Miles and Bootwalla, 1991). According to the currently adopted definition by FAO, probiotics are: “live microorganisms which when administered in adequate amounts confer a health benefit on the host” (FAO/WHO, 2001). More precisely, probiotics are live microorganisms of nonpathogenic and nontoxic in nature, which when administered through the digestive route, are favorable to the host’s health (Guillot, et al., 1998; Thomke and Elwinger, 1998,).

Introduction

Integrated Pest Management (IPM) has evolved over the last five decades since Stern et al. (1959) first gave the concept of integrated control. The basic tactics of IPM were developed and applied to reduce crop losses against the ravages of pests before the term IPM was coined (Jones, 1973; Smith et al.,1973). Entomologist at the university of California, United State of America (USA) played a pivotal role in developing IPM tactics (Perkins, 1982). Development of resistance to insecticides and the elimination of natural enemies by insecticides led to the development of ‘supervised control’. The publication of the book ‘Silent Spring’ written by Rachel Carson (1962) was a defining milestone for it brought the problems caused by pesticides to the attention of the public and the scientists. The term ‘integrated pest management’ was used for the first time by Smith and van dan Bosch (1967). In the last five decade many synthetic pesticides have been banned. In 1972, ’integrated pest management’ and its synonym were incorporated into English dictionary and accepted by the scientific community (Kogan, 1998). IPM is the main strategy accepted for pest management under agenda 21 of the United Nations conference on Environment and Development (UNCED, 1992).

Information technology is set to become important in agriculture in the coming years. In the last few decades, the application of computers and communication technologies has led to the development of a plethora of information of all types in the area of plant protection science. These information bases are available on CD-ROM, on-line form in various hosts and via mail over internet, multimedia data bases, Decision-Support Systems (DSS)/Expert Systems (ES), Simulation Models (SM), etc.- to cite a few of the latest developments. Further, cyber space is fast emerging as an area of information technology, particularly in the field of crop pest management (Srivastava and Swain, 1998). The application of information technology in pest management has been one of the most exciting developments in the field over the last decade. From the 1960s, the entomologists began using computers for spray scheduling, population modeling, exploring control strategies and managing pest monitoring data. More recently, computers are being utilized in pest management delivery systems and decision support systems (DSS) designed to enhance decision making.

Introduction

Fruits, oldest forms of food known to man, are not only good source of nutrition to the body but also have medicinal property and treat ailments. Fruits like apple, lemon, orange and pomegranate aid in proper functioning of the heart. Nutrients in apple, date and mangoes sharpens memory, prevents exhaustion, hysteria, insomnia and mental tension. All berries are rich in iron, phosphorus and sodium which are essential minerals for blood building and nervous system strengthening. Liver ailments, indigestion and rheumatism can be cured by the use of Lemons. Watermelons are good kidney cleansers. Pineapple, pomegranates help in soothing inflammation of nose, throat, fever and other chronic or bronchial ailments. Grapefruit juice is an effective aid for common cold. Fresh and ripe fruits like grapes, apples, bananas and figs are good for all brain deficiencies. Even the kernel of walnut is a helpful remedy for weakness of the brain.

Delineating species boundaries correctly and also identifying species are crucial to the discovery of life’s diversity because it determines whether different individual organisms are members of the same entity or not (Dayrat, 2005). The identification of species depends on the knowledge held by taxonomists whose work cannot cover all taxon identification requested by non-specialists. To deal with these difficulties, the ‘DNA Barcode of Life’ project aims to develop a standardized, rapid and inexpensive species identification method accessible to non-taxonomists.

DNA barcoding is a technique in which species identification is performed by determining and comparing the sequences of several hundred base pairs of nucleotides from a small fragment of an identified gene, with the aim of contributing to a wide range of ecological and conservation studies in which traditional taxonomic identification is not practical (Krishnamurthy and Francis, 2012). The two main ambitions of DNA barcoding are to assign unknown specimens to species and to enhance the discovery of new species and facilitate identification, particularly in cryptic, microscopic and other organisms with complex or inaccessible morphology (Hebert et al., 2003a). Apart from these, identification of species previously defined by other criteria to also is an objective of barcoding. Another major objective could be the definition of operational units for ecological studies. This may also be used for forensic purposes by linking the specimens with already identified databases.

Spices are defined as a strongly flavored or aromatic substance of vegetable origin, obtained from tropical plants, commonly used as a condiment. India is known as ‘land of spices’. Chilli (Capsicum annuum L.) also known as hot peppers and Capsicums also referred as bell peppers or sweet peppers belong to the genus Capsicum which is a member of the Solanaceae family. The native home of chilli is considered to New Mexico with secondary origin at Guatemala. They are known from pre-historic remains of Peru. Chilli was introduced into India by Portuguese in 16th century. Chilli is considered as one of the major commercial crops of the world. Both green and dried chillies are the important components of our routine diet. Chilli also contains vitamin A, C and E. It will give the required pungency, colour, taste and flavour to our dishes. The presence of capsaicin in chilli is responsible for its pungency and it has medicinal value. The extracted capsaicin is used in pain balms, cosmetics and medicines related to heart diseases. Capsanthin, a pigment in chilli is used for natural colouration to Jams, Jellies and squashes, since it is a natural pigment and no harmful or side effects on human health. Oleoresin is used in pain balms, vapours, etc. Hence, there is lot of demand for chilli oleoresin in the world market. The largest producer of chillies in the world is India contributing 52 per cent of world production, accounting for 11.67 lakh tonnes of production from an area of 7.5 lakh ha with 1550 kg/ha of productivity followed by Nigeria (17%), China (16%), Peru and Bangladesh (6%). India exported 1.8 million tonnes of chilli during 2009 (Reddy, 2010).

Borer pests cause significant yield losses and are one of the most serious production constraints in tropical vegetable production. For instance, eggplant fruit and shoot borer (EFSB), Leucinodes orbonalis Guenée (Lepidoptera: Pyralidae) reduces yield as much as 70% (Dhandapani et al., 2003). Tomato fruit borer, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) causes about 5 to 55% loss in almost all the tomato producing areas in the world (Kashyap and Batra, 1987). Up to 80% yield losses have been reported in various vegetable and grain legumes due to legume pod borer (LPB), Maruca vitrata F. (Lepidoptera: Pyralidae) damage (Singh et al., 1990; Sharma, 1998; Gressel et al., 2004; Hammig et al., 2008; Zahid et al., 2008). Due to higher yield losses, growers tend to apply extremely high quantities of chemical pesticides to control borer pests on vegetable crops. Because the borer larvae are exposed on external plant parts only for a brief time after hatching, the window for effective pesticide application is very brief; vegetable farmers spray throughout the growing season, but without satisfactory results. A survey of pesticide use in Bangladesh indicated that farmers spray up to 180 times with chemical insecticides during a year to protect their eggplant crop against EFSB (SUSVEGAsia, 2007). Pesticide application often exceeded 50 sprays per tomato crop season in south India (Nagaraju et al., 2002). In Bangladesh, country bean (Lablab purpureus) is being sprayed at weekly or biweekly intervals—sometimes every day—to control LPB (Hoque et al., 2001). On average, farmers used 10-24 kg/ha of pesticides in cabbage and cauliflower in India to manage the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae) and other pests (Weinberger and Srinivasan, 2009).

Cashew research in India dates back to 1950’s when Indian Council of Agricultural Research sanctioned ad-hoc schemes in the then composite Madras, Travancore, Cochin and Bombay States. Thus, Kottarakkara (Kerala) in 1952; Ullal (Karnataka in 1953 and Vengurla (Maharashtra) in 1957 came into being as pioneering cashew centres in the country. More research schemes were started with ICAR’s assistance in 1955 at Bapatla (Andhra Pradesh) and in 1956 at Deragaon (now shifted to Kothiali) in Assam. During the period, Central Food Technological Research Institute, Mysore and National Chemical Laboratory, Pune were also engaged in developing technologies for economic utilisation of cashew apple and Cashew Nut Shell Liquid (CNSL). In the second phase of strengthening cashew research in India, the ICAR started All India Spices and Cashewnut Improvement Project in 1971 linking countrywide network among different research centres. Collection, conservation and evaluation of germplasm, hybridization and selection, vegetative propagation, and nutritional studies were the primary areas under this programme.

Maharashtra, the first state was to release cashew variety under the name Vengurla-1 through Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli in the year 1974. So far, 8 varieties have been released from Regional Fruit Research Station, Vengurla (M.S.), of which, Vengurla-4, Vengurla-6, Vengurla-7 and Vengurla-8 are widely accepted for commercial plantation.

Cashew apple, a highly potential nutritional source, is almost entirely wasted now. In Goa, cashew apple juice is fermented and distilled for production of alcohol. Cashew apple is juicy and swollen. It is a rich reserve of vitamins and minerals. The cashew apple is the peduncle of the nut. Normally the apple is 8 to 10 fold large by weight compared to cashew nut, at ripe stage. Cashew apples can be of different size and shape. The ripe apple is very juicy and fibrous with thin skin. When fully ripe, it gets detached from the pedicel and falls down. In Brazil, cashew is a popular fresh fruit and dwarf types are being evaluated to fulfil the market requirements of fresh cashew apple in terms of red colour, high sugar, low tannin etc.

Water is indispensable for human, animal and plant life. Water is essential part of protoplasm. It is essential for photosynthesis. About 400 to 500 litres of water is necessary for the production of  a kilo of plant dry matter.
 
Irrigation

It is the human manipulation of hydrological cycle to improve crop production and quality and to decrease the economic effects of drought. Israelsen and Hansen (1962) defined irrigation as the artificial application of water for the purpose of supplying moisture to plant growth.
