The species is commonly found in tanks, ponds, lakes, reservoirs, canals, swamps, etc in freshwater plains. It is air-breathing in nature and survives easily low oxygen stress. During drying-up of water bodies in summers, it has been reported to penetrate deep under moist-earth and come out live on arrival of rains. The name 'murrel' encompasses its resemblance to reptile (snake) due to presence of body scales all over its body including head region. Fully-grown adults are dark greenish brown with faint black and white vertical bands visible across its entire abdominal length below the lateral line and a black ocellus at posterior end of dorsal fin.

Striped murrel is one of the important food fish of high commercial value due to preference for its meat quality, therapeutic and antinociceptive properties and hence consumed by many to induce healing and pain control after clinical operations. It contains high arachidonic acid (AA), which is a precursor of prostaglandin that may initiate blood clotting and enhance tissue growth. Geographically, the species is distributed in Western to Southeast Asia including Bangladesh, Cambodia, China, India, Indonesia, Lao People’s Democratic Republic, Malaysia, Myanmar, Nepal, Pakistan, SriLanka, Thailand and Vietnam (Chaudhary, 2019). It is supposed to be introduced in countries like Fiji, New Caledonia (Welcomme, 1988), Madagascar (Stiassny and Raminosoa, 1994) and Hawaii (Courtenay et al., 2004). The species has been reported to grow to a length of 100 cm (Rahman, 1989) and categorized„ Least Concern under the IUCN Red List (IUCN, 2020).

Globally, 92523 ton of striped murrel is produced (FAO, 2016), of which the major share of 70802 ton is contributed from capture fisheries and 21721 ton from aquaculture (Figure 1). Though capture fisheries of striped murrel is quite stable in terms of global production, the aquaculture has shown a steady rise in last two decades. In India, though no production data is available, the production of this species is mainly contributed from the capture fisheries with meager contribution from aquaculture. This has caused serious stress in past few years on its resources, more particularly due to habitat degradation and man-made hazards in aquatic ecosystem.

1.1 Importance of Water for Agriculture

All animals and plants require water for their survival. Animals cannot prepare their own food. They depend on plants for their food. Plants need water for preparation food by the process of photosynthesis. Majority of this water requirement of the crops is met from different forms of precipitation. However, when the water requirement is not fully met from precipitation, then growth of the crops is affected. Water requirement of crops depend on many factors. It depends on the type of crops, irrigation schedules practiced, soil texture, position of groundwater table below effective root zone of the crop and management practice followed in crop cultivation. The dry land crops need less water compared to rice which is a water loving crop. The perennial crops like sugarcane, banana etc. need more water than other crops like cereals, pulses, oilseeds etc. Water requirement of crops is partly met by the upward flux of groundwater. The capillary rise of shallow water table in the form of upward flux helps in meeting the water requirement of crops to some extent. The upward flux depends on the type of the soil, effective root zone depth of the crop, depth of water table below effective root zone depth of the crop and potential gradient of soil moisture suction. If the soil is heavy like clay, effective root zone depth of the crop is more (deep rooted crop) and position of ground water table is near to ground level (shallow water table), then the upward flux is more.

Due to rainfall or application of irrigation water, some amount of water is recharged to soil reservoir. This recharged water is stored in the soil as soil moisture content. The stored moisture or called as water in the soil reservoir helps in supporting water requirement of crops also. The heavy soil like clay has more moisture retention capacity than the light soils like sandy soil. The residual soil moisture held in clay soil is released slowly and supports more soil moisture to the crops for a longer period than the sandy soil which has less soil moisture retention capacity. After meeting the water requirement of crops from all sources including different forms of precipitation, ground water contribution by capillary rise and residual soil moisture, if there is any shortage of water, then this shortage should be met from other sources which are called as irrigation. It is to be noted that irrigation is not the natural phenomenon of supply of water; rather it is the artificial means of supply of water to the crops. Irrigation may, therefore, be defined as the science of artificial application of water to the crop in accordance with the crop requirement for better nourishment of the crops.

1.1. Prologue

In present era, agriculture is a cause of global concern in the context of price volatility with a rising trend growing concerns for food security and resultant trade restrictions, global economic conditions in the recent past, the forecasted rate of reduction of growth of agricultural land over the next two decades, increasing mismatches between supply of agricultural products in relation to growing demand and the climatic changes which are wielding pressures on agricultural production. Thus, enhancing agriculture production and productivity have emerged as a global challenge. India, with 2.4 per cent of the world’s geographical area, is the largest producer of pulses, tea, and milk and second largest producer of fruits, vegetables, wheat, rice, groundnut and sugarcane in the world but supports about 16.2 per cent of the world’s population. Coupled with small scale land holdings and deep rooted poverty in rural areas, the magnitude and dimensions of challenges for agriculture policy-makers have increased manifold. So far as the agriculture sector in Odisha is concerned, it contributes only 15.6 percent in 2013-14 towards State Gross Domestic Product (SGDP), but provides employment and sustenance to more than 60 percent of the total workforce of the State. In this sense, the agriculture sector is still the mainstay of the economy of Odisha. According to the Economic Survey 2013-14 of Odisha, despite wide annual variations in its growth, the agriculture sector had grown at a rate of 12.72 per cent in 2012-13. However, a negative growth of 3.53 percent is anticipated during 2013-14 due to cyclonic storm Phailin and flash floods in the State in October 2013. The real per capita income of Odisha was Rs. 25,891 in 2013-14 which was around 65 per cent of All-India real per capita income of Rs.39, 961. According to the 68th round of National Sample Survey Organization (NSSO), the monthly per capita consumer expenditure (MPCE) for rural and urban Odisha is below the respective national averages. In the food and non-food consumption behaviour, an average Indian spends more than an average person in Odisha. In short, the above parameters pinpoint that the State of Odisha has been lagging behind the national economy & highlights the necessity of achieving higher growth on a sustainable manner across the sectors particularly the agriculture sector in order to uplift the society from underdevelopment & poverty. Though the contribution of agriculture to Net State Domestic Product (NSDP) has declined, the percentage of workforce engaged in agriculture has remained somewhat unchanged. This implies that there has been an overcrowding in agriculture without any noticeable increase in production.

Agriculture has been the base of human livelihood since ancient time when the man started planting of seeds of some edible plants now called Agricultural crops. Domestication of food plants and animals was started with the development of human civilization. Thus agriculture can be explained as science and technology of growing food crops and rearing of animals. Still in several countries of the world, most of population is based on agriculture for their livelihood particularly in rural areas of that country. According to Williams and Haq (2002) there are over 7000 species of plants that can be used for food. The edible plants species grown for food are called agricultural crops. The crops grown in garden are known as garden cops or Horticulture crops. Horticulture is a branch of agriculture, which deals with intensive cultivation of garden crops such as fruits, vegetables, f lowers, ornamental plants, plantation crops, spices, medicinal and aromatic plants, and mushroom. It also deals with post-harvest technology of horticultural crops. Processing and Preservation of fruits and vegetables is a part of Post-harvest Technology of horticultural crops which deals with methods of processing and preservation of these crops to extend the shelf life of fruits and vegetables after harvesting.

All horticultural crops have their own importance in our society. Fruits, vegetables and spices are major ingredients of our meal. Spices add taste and flavor to our food and also have high medicinal values. Flowers and ornamental plants are used for decoration of environment and landscape. Aromatic and plantation crops have become industrial crops. Mushroom growing is a great enterprise. Among these crops fruits and vegetables are major crops and have been considered presently as highly economical and important food crops. There are 1200 crop species are used for vegetable purpose in the world (Hazra and Som, 2006). Fruits and vegetables are richest and cheapest source of all essential nutrients (carbohydrates, fat, protein, vitamins and minerals) required by our body for proper functioning of body organs and maintaining good health. Besides these nutrients they also supply water and fibers to our body which play vital roles in our body. Fruits and vegetables have important place in our daily diet and based on survey made by experts FAO WHO (2003) has recommended 400 g/capita/day of fruit and vegetables (fruits -100 g/capita/day and vegetables -300 g/capita/day) to be consumed for good health and prevent chronic diseases. Therefore, the demand of these food commodities has increased in the modern society due to increased awareness of the nutritional importance of fruits and vegetables. So that people must be aware that what part of fruit and vegetable is to be consumed?

Human beings, considered to be the highly evolved living organisms, have been making consistent and constant efforts to lead comfortable life without much concern for the conservation of nature and adversities to other living and nonliving entities existing in the universe. To meet the requirements of food, feed, fibre, timber and other needs, the plants that could supply the above were selected and domesticated. When the useful plant species were cultivated over large areas repeatedly year after year, the problems afflicting plants that were not recognized earlier as constraints for crop cultivation, assumed monstrous proportions wiping out entire crops and ruining the livelihood of the people of that geographical location/country. World history is replete with numerous instances of huge crop losses caused by microbial plant pathogens resulting in malnutrition, hunger and death. Migration of millions of people to other countries for their survival, became unavoidable. Such historical evidences threatening the existence of humans necessitated to investigate the causes of destructive diseases like late blight and heliminthosporiose diseases affecting respectively potato and rice, the staple food of the largest populations of the world. In order to take appropriate measures for minimizing losses due to crop diseases and to mitigate the sufferings of man and the animals, application of various short- and long-term disease management strategies has become indispensable for the profitable cultivation of crops

1. FOOD AND ITS SIGNIFICANCE

Food is the basic necessity of all the living world and the man is no exception to this. The basic purpose of food is to provide energy for the routine body functions and protect the body from various diseases. Life cannot be sustained without adequate nourishment for a healthy and active life, diets should therefore, be planned and consumed on sound nutritional principles (Fig. 1). For want of nutritious foods, consequence is the prevalence of malnutrition. There are several diseases that are related with deficiency of nutrition food, if not consumed. Such diseases include Kwashiorkor that can develop in children consuming insufficient protein even if total calories are sufficient. Marasmus is often due to the cessation of breast feeding and the attempt to replace it with foods, inadequate in protein such as rice broth. Other nutritional diseases still found particularly in the developing world are childhood blindness (vitamin A deficiency), rickets (vitamin D deficiency), beri-beri and infantile beri-beri (inadequate thiamin intake), pellagra (inadequate niacin intake), anemia (iron deficiency), goiter (iodine deficiency), etc. To cope up with this, the diet needs to be supplemented with nutritious food components including fruits and vegetables to make it more suitable for the growth and development of body.

Out of different types of foods, the fruits and vegetables constitute an important component of the food. Horticultural crops occupy a prominent position both in the importance and production in the world. The temperate fruits and vegetables are an important part of the horticultural crops, in terms of production and role in human health. These crops assume all the more importance due to their antioxidant activity, and presence of minerals and vitamins. Both fresh and processed fruits and vegetable, their different products are consumed. They are also called as protective foods. Fruits and vegetables are major sources of important vitamins like B and C and minerals such as Ca, Fe, P and K.

Plant breeding is described as an art and science of changing the genetic architecture of plants with a goal towards betterment of mankind. Apart from this generalized concept, plant breeding is accomplished through inter-disciplinary mode assorted from simple selection in a variable plant-population having some desirable traits to the application of biotechnology and more. Worldwide, cultivars of different crops are routinely manufactured by Multinational and National level Industries, Government Institutions, Universities, Crop specific Organizations, professional plant breeders and even by the individuals such as gardeners and farmers.

Plant breeding is basically operated by the principles of Genetics where selections are practiced from a variable population and the selected variation needs to be inherited. Three categorized broad goals of plant breeding are 1) high yield 2) uplift in quality and 3) resistance against biotic and abiotic stress.

Spice crops are known to add nutritive value and increase the palatability as well as quality of food. Therapeutic uses of spices are also well recognised. The spice industry in India and trade has shown stunning progress over the last 5 years with 120% increase in revenue which is very close to touch $ 3 billion. East Asia is the major market for spices, followed by America and the European Union and the world spice trade has almost touched $ 17 billion by 2020. So, increased production is of paramount importance across the world and the potential is increasing. On the other hand, quality improvement is one of the primary objectives of spice crop breeding apart from achieving high yield. Cultivar and species diversity are the principal components of diversity of spices (Sasikumar et al. 1999; Krishnamoorthy et al., 1997; Prasath and Venugopal, 2004). A good amount of variability is found in many important Indian spices like black pepper, cardamom, cinnamon, curry leaf, ginger, garcinia, tamarind and turmeric. A number of cultivars have been released followed by intra-germplasm evaluation and selection in spices. Contribution of recombination breeding is less in spice crops with regard to other field crops and a number of valuable varieties have been bred by clonal and seedling selection (Peter, 2008). Deployment of high yielding, water use efficient, climate resilient genotypes and technologies are also necessary.

Oilseed Crops consist of those groups of plants cultivated for substantial quantities of the oil, vegetable fat obtained from the seeds (endosperm) of the plants.

The major oilseeds grown world over are soybeans, sunflowers, rapeseed – mustard (or canola in USA & Canada), groundnuts (peanuts) and linseed. Seed oils from flax (linseed) and castor beans are used for industrial purposes. These Oilseed crops including oilseed bearing trees are the basic biological systems that produce oils, contributing to renewable energy production, help stabilize greenhouse gases, and mitigate the risk of climate change (Jaradat, 2016)

The oilseed crops are of heterogeneous group of plant species not having any common morphological and genetic features except production of seed oil. Crops like groundnut, sesame, castor bean, soybean and niger are grown during the rainy season and the others like rapeseed and mustard and safflower are grown in the post rainy season. Sunflower, however, may be grown in both the seasons. Hence the individual crops forming the conglomerate of Oilseed crops have to be treated differently for their improvement and production. Nevertheless, all of them produce a common end product viz., oil or vegetable fat, the importance of which is growing in product development, commerce and human and farm animal nutrition. The oilseed bearing crops have to be treated as a unique group in terms of research and development to come up with strategies for their judicious exploitation in the national farm economy. From the scientific point of view, the oilseed crops are energy rich and offer impressive potentials in terms of realizable production levels and valuable product development. In India good progress has been achieved so far in research and development of some oilseed crops; but there exists a need to scale to newer heights in terms of realising the hidden potentials of oilseed crops through basic and strategic research, with an integrated approach.

A model is something that mimics the behavior of some real system of interest. Our interest here will be in water quality models, which are usually equations, and which predict some result based on factors that influence that result. A water quality model is a representation of a real system. The essence of a good water quality model is that it is simple in design and exhibits the basic properties of the real system that we are attempting to understand. The model should be testable against empirical data. The comparisons of the model to the real system should ideally lead to improved mathematical models. The model may suggest improved experiments to highlight a particular aspect of the problem, which in turn may improve the collection of data. Thus, modeling itself is an evolutionary process, which continues toward learning more about certain processes rather than finding an absolute reality.

Water pollution is a large set of adverse effects upon water bodies such as lakes, rivers, oceans, groundwater caused by human activities. Although natural phenomena such as volcanoes, storms, earthquakes etc. also cause major changes in water quality and the ecological status of water while these are not deemed to be pollution. Water pollution has many causes and characteristics. Increases in nutrient loading may lead to eutrophication. Organic wastes such as domestic sewage and farm waste impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole ecosystem. Industrial discharge a variety of pollutants in their wastewater including heavy metals, organic toxins, oils, nutrients, and solids. Discharges can also have thermal effects, especially those from thermal and nuclear power stations, and these too reduce the available oxygen. Siltbearing runoff from many activities including construction sites, forestry and farms can inhibit the penetration of sunlight through the water column restricting photosynthesis and causing blanketing of the lake or river bed which in turns damages the ecosystems the process is called as eutrophication.

Pollutants in water include a wide spectrum of chemicals, pathogens, and physical chemistry or sensory changes. Many of the chemical substances are toxic or even carcinogenic. Pathogens can obviously produce waterborne diseases in either human or animal hosts. Alteration of water’s physical chemistry include acidity, conductivity, temperature, and excessive nutrient loading. Even many of the municipal water supplies in developing countries can present health risks leads to many diseases.

Insects are the most successful arthropods in animal kingdom. They are found in almost all habitats on earth except for the frozen polar environments at the highest altitudes and in the immediate vicinity of active volcanoes. They are the only invertebrate animal (animals without backbones) with wings. The success of insects on the planet is due to their ability to fly and rapidly colonize new habitats. The study of insects is called entomology and entomologists are those scientists who study about insects.

While fertilizer injectors that mixes fertilizer solutions with the irrigation water flow in the micro irrigation systems, a scientifically prepared fertigation schedule is the software that farmers need to implement a successful fertigation plan.

Though water soluble fertilizers are a special grade of fertilizers manufactured for fertigation per se; I have been assisting farmers to do fertigation with conventional fertilizers, those are familiar to them; like Urea for N, white muriate of potash (MOP) for K. Only in the case of P source they need to acquire water soluble special fertilizers like Monoammonium Phosphate (MAP) or Phosphoric acid. Historically, fertigation by our small holder farmer began in India just by fertigating Urea alone. And applying P and K as direct dry application to the soil with Single Super Phosphate (SSP) or pink MOP, both are not water soluble. Gradually, when farmers realised that fertigation is giving them more yield of the crop and income they warmed up to the idea of full fertigation and demand for water soluble fertilizers like MAP, White Potash, SOP etc. grew.

The term digital is derived from the word digit or digitus, a Latin word for finger, as fingers are often used for discrete counting. A variable is discrete when it is countable in a finite time and its instantaneous value at any timing/ instant belongs to a set of finite values.

This research seeks to address some major concerns of communication through cyberspace and its socio-cultural implications. In particular, it seeks to address the use of cyberspace or Internet as a potential medium of communication for the people of Odisha and the relatively positive and negative outcomes of the use of this medium. It investigates the current Internet-mediated communication practice in the twin city (Bhubaneswar and Cuttack) of Odisha and explores the social and cultural implications of the new communication mode.

Soil is the most fundamental resource to fulfill basic requirements of food, fiber and shelter of human race. Although soil is perceived as something of insignificant value and it is considered as dirt but humans cannot survive without soil. Soil forms
basis for all terrestrial life. Soil provides a wide range of ecosystem services (Table 1) that make humankind to survive and progress.

Plants are used as medicine since time immemorial. One of the area of Ethnobotany, Ethnopharmacology is considered as the scientific evaluation of traditional medicinal plants (Cotton, 1996). Cox (1994) has suggested that the ethno-directed sampling is most likely to succeed in identifying drugs used in the treatment of gastrointestinal, inflammatory and dermatological complaints. The Plant kingdom is a virtual goldmine of potential drug targets and other active molecules awaiting to be discovered. It has been estimated that only 10 - 15 per cent of the 7,50,000 existing species of higher plants have been surveyed for biologically active compounds.

India is an agriculture based country which is one of the few developing countries in the world. It successfully achieved Green Revolution during the late 1960s (1967-68). At present, agriculture is a principal means of livelihood for over 58.4 per cent of Indiaís population directly or indirectly (Anonymous, 2011). It is worthwhile to mention that although agriculture continued to be the mainstay of the Indian economy previously (Anonymous, 2010b) yet now its share in the Indian economy is declining year after year (Anonymous 2013d). After Independence, agricultureís sector contribution to GDP swings between 50-60 per cent. Even in 1950-51, it was 55.1 per cent, but fell to mere 17-18 per cent in 2008-09 (Mahajan and Gupta, 2009).

A ‘spice’ is a seed, fruit, root, bark, bulb, corm, rhizome or any other part of a plant primarily used for enhancing the taste, flavor or color of food. Some spices serve as preservative of food substances. Many spices have antimicrobial properties. Spices are sometimes used in medicines, religious rituals, cosmetics, perfumes etc. Spices are more commonly used in countries having warmer climates, especially in meat preparations. Many spices have substantial antioxidant property due to the presence of phenol compounds, particularly flavanoids.

India is the major producer of spices and contributes about 75 per cent of world’s spice production. Developing and under developed countries of the world supply about 55 per cent of spices to the global markets and the major markets in global spice trade are the United States of America, The European Union, Japan, Singapore, Saudi Arabia and Malaysia.

Since shrimps live and grow in water, water quality has an impact on their growth and survival. Water of good quality means that the parameters influencing shrimp growth and survival rates are within the optimal range of shrimp requirements. Each water quality parameter can have a direct impact on the health of the animals. Shrimp suffer from stress and disease when exposed to improper levels of dissolved oxygen, ammonia, nitrite, or hydrogen sulphide. Water quality parameters, however, influence each other in the complex and dynamic environment of aquaculture ponds. 

Agricultural crops are being affected by a wide range of organisms such as insects, mites, fungi, bacteria etc. Another important and unseen enemy is known as plant parasitic nematodes. The study on nematodes is known as Nematology.

India had fourfold increase in population from 0.3 billion to 1.34 billion and registered a fivefold increase in food grain production from 50 million tons to
285 million tons in 2018 (Paroda, 2020). 

There are many bacteria and fungi which produce biofilms. These are made up of living, reproducing microorganisms. These microbes form communities and adhere tightly to the surfaces and are resistant to many antibiotics. Many pathogenic microorganisms form biofilms which are difficult to be removed and are harmful.Such microbial colonies produce an extracellular polymeric substance (EPS) to protect them. The dental plaque was the first documented evidence of microbial biofilms. When such microorganisms get a moist environment they attach themselves to any object and reproduce forming an attachment by secreting a slimy, glue-like substance. It is possible with metals, plastics, natural materials, medical implants, kitchen counters, contact lenses, walls of a hot tub or swimming pool. Initially it was the investigation of many scientists to show the presence of biofilms

Beneficial effects of biofilms have also been shown (Rosche et al., 2009) especially in agriculture (Bogino et al., 2013; Berlanga and Guerrero, 2016) where it can be utilized as a biological control agents. They are used as biofertilizers to enhance crop production (Timmusk et al., 2017), hazardous pollutants can be removed (Irankhah et al., 2019). 

Cataract is a common cause of visual impairment and blindness in dogs and has a wide variety of aetiologies, as well as the disabling effect on the animal. Cataracts present important welfare considerations for the owner. Visual impairment in dogs may lead to increased nervousness, aggression and reluctance to exercise, all of which may adversely affect the owner-pet relationship (1). The only effective mean of treatment for cataract is surgical extraction of diseased lens (2).

Although vision is one of the important faculties for any living individual, dogs have very well developed olfactory lobe and have great sense of smell. They can move about easily in limited area familiar to them even with impaired vision. Cataract surgery was therefore not a common procedure in animals for many years. Quite often however,

Canine domestication is an age-old practice which started with guard for humans and other animals, dogs being the favorite companion animals. They have many positive social effects on lives of their owners including enhanced emotional sense and companionship and even reduction of anxiety and mental disorders. Though dogs have proven good for human health, it should be kept in mind that are prone to many disorders and infectious diseases. Healthy life of dogs is attributed to healthy lifestyle, good feeding practices and regular medical care. In addition, an equally important practice is vaccination. Since dogs live in close proximity to human beings and their environment, regular check on their immunity becomes essential, especially when kept as indoor pets. Their illnesses vary from minor issues like dental tartar to fatal diseases like tumors and rabies. Depending upon lifestyle patterns and subsequent body parameters, many predisposing factors increases the susceptibility of dogs to various diseases.

Agriculture depends mainly on natural resources like land situation, soil, water and a favourable climate. Continuous agricultural practices adopted without conservation of such precious resources may lead to unsustainability of growth in agriculture. Conservation of these resources and their sustainable use with appropriate measures would be required for a sustainable agriculture.

The large and diverse livestock resources of India benefit millions of people in rural areas, enhancing their standard of living. The key elements of sustainable agriculture are livestock resources. India has a population of 535.78 million livestock. According to 20th livestock census 2019,India ranks first in the world for the number of buffalo (109.85 million), second in number of cattle (192.49 million), third for the number of sheep (74.26 million), fifth for the number of chickens and ducks (851.81 million), and tenth for the number of camels (2.5 lakhs). About 8.8% of India’s population is engaged by the livestock industry, which provides a living for two-thirds of the country’s rural communities.

The two limbs of Arabian Sea and Bay of Bengal form parts of North Indian Ocean (NIO) on the left and right respectively. Though the Arabian Sea and the Bay of Bengal are located in the same latitudinal belt and receive the same amount of solar radiation, oceanographically these two basins exhibit remarkable differences. The reason for it is Bay of Bengal is shallow and less saline due to heavy river water discharge and Arabian Sea is deep and cold and more saline.

Happiness is the barest minimum to any person for survival and moving with a humble vision and mission either. Unfortunately, our farmers are denied to a glow of happiness, and mantled with clouds of agony, depression and confusuion. They are supposed to ensure food security to all, but themselves have to deal with extreme food insecurity, market uncertainty, undulating income, erosion of natural resources and stereotypes of farming occupation. That is how there has been a sharp rise in the migration from farm to off farm occupation.

This is the need of the hour to estimate their happiness. Agriculture is India’s backbone, employing half the country’s population. However, it has been confronting with several issues, including unfair and non-remunerative market prices, an unstructured supply chain, disaster driven crop failure, and so on. However, an alarming trend in our country shows that farmers are desiring to quit agriculture by large number, 45-60 per cent, and are committing suicides; this is a threat to our long-term a gri-development. Do they cultivate because they desire to, or because they have got no other choices either?

Domestication is the most extensive biological experiment ever undertaken by man. It has involved millions of animals and has extended through many centuries. It still continues and animal domestication was one of the major contributory factors to the agricultural revolution during the Neolithic period, which resulted in a shift in human lifestyle from hunting to farming. There are two species of domestic duck, the common duck, domesticated from the wild mallard (Anas platyrhynchos), and the Muscovy duck (Cairina moschata). Both are members of the Anatinae. In both species, the same scientific binomial is used for the domestic and the wild forms. Inter-breeding between the two species occurs, but their offspring are infertile. Both species of domestic duck produce eggs and meat and both are valuable on farms and smallholdings for reducing pests.

Around the world, nearly one billion people live along the 3,12,000 Km long coastline. The Indian coastline runs around 8,129 Km distributed along nine coastal states, two groups of islands and two union territories. The coastal ecosystem of India forms a very valuable resource community, supporting the livelihood security of several million rural poor and also contributing the national economy in a large measure. The latest estimates by National Bureau of Soil Survey and Land Use Planning (NBSS & LUP), Nagpur, India, using Global Assessment of Soil Degradation (GLASOD) guidelines indicate that the coastal area in the country is spread over an area of 11.8 million hectares (Mishra, 2005). Yadav et al. (1983) have reported about 3.1 M ha and 2.1 lakh ha of coastal salinity in India and Tamilnadu respectively.

1.1 Background

The whole world is characterized by diverse cultures, different approaches to life, divergent outlooks and world views and dissimilar living conditions and environments. The people in it live with cultural, social, economic and educational dissimilarities, differences, inequalities, and goals. Despite the disparities in everything, the whole world is unified by Information, Communication and Technology through the global media culture, technocapitalism, and information revolution. Gone are the days when people confined themselves to their hearths, farms, educational institutions and places of work, managing their lives with basic minimum requirements and needs! 

Uncertainty is an inevitable character of any system where most of the contradictory factors are either unpredictable or unfathomable. The higher is the complexity, the lesser would be the resilience. Agricultural production system, as it is managed in Indian condition, is the most vulnerable one to a plethora of uncertainties. Mostly managed in an open air rained conditions, it has been exposed to weather and resource uncertainties comprising of market volatility, poor access to technology and a fragile input delivery mechanism. The present study examines and depicts the possible issues and reasons for uncertainty.

Growth of urban population has become a challenge throughout the world. Presently, many of the cities are featured with high rising buildings, rush of vehicular traffic and networking of industrial establishments. The urban ecological footprints are increasing day-by-day resulting in unfavourable living conditions. The cities require vast area of land to sustain the population for requirement of food, clothing and other requirements. All these items are brought from areas outside the city, may be from far or near. Creating avenue for production of food and other materials in and around the cities will certainly minimize the pressure on land available outside the city areas. The urban sustainability is at threat due to environmental pollution, rising population and intensification of non-green activities. Many cities have natural resources such as water bodies, inherent vegetation, open space, etc.; which can be appropriately utilized for productive purpose. Promotion of urban agriculture in the form of growing crops, planting trees rearing animals and encouraging landscape garden will have long term impact on urban ecosystem. This can prevent environmental degradation, ensure supply of fresh food and improvement in urban life.

Vegetables are defined as edible herbaceous plants or parts of plants consumed as raw or after cooking and are rich in vitamins and minerals, low in calorific value and neutralize the acid substances produced during digestion of high energy foods. Olericulture is a branch of horticulture that deals with production, storage, processing and marketing of vegetables and has its origin when man started growing vegetables for human consumption. The term Olericulture comes from Latin words holus-holeris = any kind of culinary vegetable, pot herb, and cultura = to cultivate.

Vegetable crops include a large number of plants, mostly annuals and a few perennials, grown for their edible leaves, stem, flower buds, flowers, fruits and roots. Vegetables are integral part of a balanced diet and are considered as “Protective foods” as their consumption prevent several diseases. They have a prominent role in combating malnutrition of animals and human beings.

The word ‘horticulture’ was first conceived by Peter Laurinburg. In an English language, the word horticulture used for the first time in 1678 in a book entitled “New World of Words” by Phillips. The term HORTICULTURE is resultant of two Latin words i.e. HORTUS meaning GARDEN and CULTURA meaning CULTIVATION.

The Latin term ‘Garden’ meaning to enclose. In past, the garden had protection with with walls or other similar structures. Such protected places were used to grow fruits, vegetables, flowers and ornamental plants. When fruits are grown in a definite area, that area is called as an ‘orchard’. Thus, horticulture refers to cultivation of garden plants in protected enclosures. It is an aesthetic science deals with the garden crops. Such as growing of vegetable crops in vegetable gardens; fruit crops in fruit gardens. The most distinguished character between horticulture and agriculture is that horticulture deals with small scale gardening and usually in enclosed gardens although this is not a necessity, while agriculture is done on large scale with extensive crop cultivation.

Soil is a natural resource that exists on the planet much before the existence of mankind on it. The human relationship with soil throughout the history of mankind has marked its ability of crop production and influenced the success of civilisation. Such relationships also affirm soil as the foundation of agriculture and food security, supplying all the essential ingredients to plants, as fundamentals to life on planet, and support various biogeochemical cycles on earth’ s terrestrial ecosystem. Prosperity of human society depends on the utilisation of planet’ s resources in creative and productive ways. Of these resources, soil has gained much importance as it provides human to sustain themselves with their capacity to food production, to make significant contribution towards biodiversity and other ecosystem services that are vital for the functioning and resilience of earth’ s environment. Soil occupies a pivotal position in the environment to maintain its quality.

1.1 Perspective

From the very dawn of evolution of human beings, man has been using plants as food, for wellness and as medicine to alleviate diseases and discomfort. People living in different parts of the world, both new and old, in the centres of some of the oldest civilizations, had selected organisms from time immemorial for food and medicine by a process of trial and error or even by experimentation with the biological resources, particularly among the plants growing around them. These have been referred to as ethnic food/traditional food and ethnic medicine/traditional medicine. India is one of the mega centres of biodiversity, and that of the ethnic diversity, that evolved over millennia with settlement of diverse races coming from different regions of the world, besides the indigenous people. Thereby, it inhabits some of the most diverse cultural traditions. This process has led to further evolution of some of the oldest indigenous civilizations originated in the Indian Subcontinent with amalgamation of exotic traditions and the knowledge. Integration of the knowledge associated with the use of plants with medicinal properties has enriched its great heritage of medicinal plant use, the Ayurveda, i.e., the knowledge of life and longevity, dating back to the pre-historic and the early Vedic period.

India, the second most populous country in the world after China, is trying hard to provide basic needs like food, shelter, clothes, electricity and education facility to its 1,316 million people and to upgrade itself from the stage of ‘Developing economy’ to ‘Developed economy’. Table 1.1 depicts the trend of population increase from 1154 million to 1316 million during 2009 to 2018 with diminishing growth rate from 1.42% to 1.12%. Growing demand of ever increasing population has been met so far by over exploiting natural resources like land, water, fossil fuels, forests and mineral resources which resulted rapid unplanned urbanization, quick depletion of fossil fuels, more and more waste generation, alarming increase in environmental pollution, deforestation with loss of plant and animal species, desertification of cultivable land due to soil erosion, soil contamination & soil salinity and increase in health diseases due to malnutrition, starvation and environmental pollution.

India is well known for its rich flora and fauna and is referred as one of the richest biodiversity nations of the world. The mammalian population of India is a combination of Palaearctic, Oriental and Afro-tropical fauna (Sahajpal et al. 2009). It is the home of 400 different mammalian species, 129 of these species are protected under Wildlife (Protection) Act 1972 (India) and an arbitrator to Convention on International Trade in Endangered Species (CITES) (Nameer, 2015). Illegal trade of the wildlife for preparation of various products is the common issue in the conservation and is also responsible for regional extinction of the species.

Participatory curriculum development (PCD) in extension education is an emerging approach to help and improve the quality of education in farm universities. The main steps of the PCD approach adopted here have high practical utility for the design of formal course contents for the Undergraduate and Postgraduate courses in Agricultural Extension. A great deal of thinking is required while deciding on how much participation will be required from which stakeholders, at what level(s).

Cytology is the study of cells from fluid or tissue samples prepared directly on glass slides and stained for microscopic evaluation. It is also described as examination of cells without regard to the tissue's architectural details.

It is less invasive than tissue biopsies and, in some cases, it can provide a rapid diagnosis that would otherwise take several days if done by histopathology.

When is the cytology needed?

The diagnostic methods of clinical examination, radiographic evaluation, and laboratory data suggested that a diagnosis that cannot be confirmed by these methods. In that situation, cytology is very much helpful to confirm the disease processes or conditions.

1.1 Background

The aftermath of Green Revolution has contributed to both coercions and pollution, albeit, it saved human civilization from hunger, malnutrition and impoverishment. The beginning of GR era, with the prevailing objective and condition, has got less but few choices to go for intensive cultivation that invited chemical fertilizer, assured irrigation and farm mechanizations to make the 'magic gene' revolutionizing the production, productivity and livelihood security in agriculture as well.

The welcome of exotic genes into Indian agriculture has also triggered the silent oftraditional cultivars. Nevertheless, the quantum jump of an agriculture with a production of 55 million tons to 120 million tons during 70s, has contributed to make India self-reliant in food and we have been able to earn a new esteem in the global geo-political scenario by throwing away the 'begging bowl' called PL480.

Albeit a mammoth volume of food grain production in India, 320 million tons and close to 350 million tons of vegetables production in 2023 evinces the emergence of mighty Indian agriculture over the geo-political expanse at global level, yet the income from agriculture to her 140 millions of farmers is not secured, persistent and satisfying. This is due to a mal orchestration of weather-market-job-technolgy uncertainties. The farmers producer organization offers them a new hope and aspiration for small-marginal tiny agricultural producers of India.

Introduction

Human beings are the most critical components of an organization. The organization’s survival has improved all the facets contributing to its success. In a competitive world, human resources are sine qua non in an organization. Quality of work life (QWL) is critical for deciding organizational employee- related outcomes. Human resource management has a unique role in any organization. Organizational goals in an organization are achieved through planning, organization, staffing, direction, coordination, and control. 

India is basically an agrarian economy where 57.8% of rural households are engaged in agriculture (Situation Assessment Survey of Agricultural Household, 2021). 48.9 per cent of the Indian work force is employed in the agricultural sector, (ILO, 2016). The estimated Indian population for the year 2050 is 1.7 billion which will raise our food demand to ∼400 million tonnes (Rao et al., 2018). In this context, Indian agricultural production system will have to take up the challenge to feed l7.5% of the global population with only 2.4% of land and 4% of the available water resources at its disposal.

The term “fish” is usually a convenient description for a group of cold-blooded, ectothermic, aquatic non-tetrapod craniates that breathe with gills (Nelson, 2006). Fishes exploit every nook and niche of the domain of water. They are especially noted for their unimaginable numbers and bewildering forms. Most of them have a stream-lined body covered by scales and pose fins supported by fin rays and breathed by gills throughout life. They constitute the first group of animals that have developed biting jaws in the phylogenetic history of vertebrates.

About Northeast India

A serene land tucked up in the lap of mighty Himalayas, the North East regions in India is bestowed with picturesque locale and inexorable culture. The vast stretch of land located on the foothills of Himalayas, is a glorious heritage of art, culture and festivities. The tropical beauty of India, finds itself an all new meaning when we enter this paradise of tranquility. The serene ambience and salubrious climate of the region attracts people from all over the world. It almost feels like the valley casts a magical spell upon its visitors to replenish their soul making them feel rejuvenated. The widely scattered archeological specimens in the region speak aloud about the mythological significance of this part of the country, the North East region of our country bears testimony to our rich cultural heritage.

India is primarily an agriculture based economy, which implies, agriculture dominates the nation’s economic landscape. In the course of socioeconomic growth, agriculture is crucial. Around 58 per cent of the population in India rely only on agriculture for their livelihood. In India, agriculture acts as an important source of living for about 60 per cent of the population (India Brand Equity Foundation, 2021) and almost 70 per cent of rural households depend on farming. The farming sector in India contributes significantly to the economy, making up about 29 per cent of Gross Domestic Product (GDP) (Balkrishna et al. 2021).

This chapter describes fundamental terminology and lays the foundational framework for the course. It offers a general understanding of statistics, its purpose, and its role in addressing diverse problems across various fields of study. Additionally, it explains the rationale behind choosing R software as a powerful tool for data analysis.

Basic Concepts and Terminology

Statistics is an essential tool in agriculture, helping researchers to collect, analyze, interpret, and present numerical data related to plant traits, and agricultural practices. The fundamental goal is to make informed decisions and enhance crop yields, quality, and resilience.

To illustrate, researchers choose to work with a sample due to practical considerations, such as time and cost constraints. For instance, in a field with 10,000 crop plants, a researcher aims to determine the average plant height in the field. To conserve time and resources, they randomly select 200 plants from various locations within the field. These 200 plants constitute a sample from the entire population of 10,000 plants. By analyzing the height observed in the sample, the researcher can conclude the average height of the entire crop field.

1.1 GENERAL DESCRIPTION

There is a folk tale from India which is mentioned under relevant situations. This tale teaches how different perspectives lead to different points of view. The tale of the blind men and an elephant originated in the ancient India, from where it has been widely spread to different parts of the world. This famous ancient tale mentions about six blind men who had never come in contact with an elephant during their lifetime and who know and visualize what the elephant appear like by touching it and feeling. In the tale it is highlighted that every blind man touches a different part of the elephant's huge body, but only one part, such as the leg, ear, tail, body or the tusk. These blind men then go on to narrate about the elephant on the basis of their touch and feeling and their recount of the elephant varied widely from each other. They were told that elephants could trample forests, carry huge loads and is very big in size. The six blind men were taken to the elephant and asked how it look like (Fig.1.1). The first blind man reached out and touched the side of the huge animal. "An elephant is smooth and solid like a wall!" he declared. "It must be very strong and powerful." The second blind man put his hand on the elephant's trunk. "An elephant is like a giant snake," he said. The third blind man felt the elephant's pointed tusk. "I was right," he decided. "This creature is as sharp and deadly as a spear." The fourth blind man touched one of the elephant's big ear and announced "I believe an elephant is like a huge fan or may be a magic carpet that can fly over mountains and treetops". The fifth blind man touched one of the four legs. "What we have here," he said, "is pillar of a house." The sixth blind man gave a tug on the elephant's coarse tail. "Why, this is nothing more than a piece of old rope and it appeared to him dangerous, indeed”.

Seed is the primary and most critical input in any crop production programme. A quality seed alone contributes around 15-20% towards total production. The efficacy of all other inputs to increase production will be in vain if the quality of the seed is poor. Hence, use of quality seed is crucial as it appreciably increase the productivity of the crop without depending much on other inputs. This adds to the old saying in Manu Smriti good seed in good field yield abundantly .A quality seed can be defined as genetically and physically pure seeds with high germination percentage, free from seed borne pathogens and safe moisture content. This guarantees good germination, vigorous growth, and good establishment of crop in the field.

History of Seed Industry in India

Farmers dependent mostly on traditional indigenous varieties earlier and its seed requirements were met through their own farm saved seeds or through local sources. But the quality of these seed stocks was not assured, and this resulted in drastic reduction in production as well as productivity of the crops. As a result of various crop improvement programmes, improved varieties possessing high yield potential along with additional characters of biotic and abiotic resistance came into the scenario. But the availability of the seeds of these improved varieties among the farmers remained as a problem and it limited the cultivation of these varieties. This led to the development of a well-planned systemized seed production system. Government of India had framed and brought out different legislations for regulating systemized seed production. These laws are framed to make available quality seeds and planting materials to a common farmer and equip him to approach authority for justice. Seed legislations were initiated in the country by establishment of National Seed Corporation (NSC) during 1963 under Ministry of Agriculture and the seed industry was restructured through the nationals seed projects phase I (1977-78), Phase II (1978-79) and Phase III (1990-1991). These initiatives strengthened the seed industry through formulation of seed regulations, establishment of state seed corporations and seed certification agencies thereby assured the supply of quality seeds to farmers
