Planned Strategies for Rural Development in India

The Food and Agriculture Ministry appointed a Committee to examine the Grow More Food activities of the Government which were in implementation and to suggest measures for ensuring rapid expansion of agricultural production. The Grow More Food Campaign Inquiry Committee pointed out that there was imperative “Need of an organisation for intensive rural work which would reach every farmer and assist in the coordinated development of rural life as a whole similar in conception to the “extension” or “advisory’” services in the U.S.A., the U.K. and elsewhere.” One of the recommendations of the Committee was that an extension agency should be set up for rural work, which would reach every farmer and assist in the coordinated development of rural life. The Planning Commission set up the Government of India in 1950 to formulate the First Five Year Plan summarized the reasons for failure of the earlier efforts by the governmental and voluntary organisations as follows

Evolution of Panchayati Raj System in India

In January 1957, the Government of India appointed a committee under the chairmanship of Balwantray Mehta to examine the working of the Community Development Programme (1952) and the National Extension Service (1953), and to suggest measures for their better implementation. The committee expressed concern about the lack of participation of people in these programmes and made a string plea for devolution of power. The committee submitted its report in November 1957 and recommended the establishment of the scheme of ‘democratic decentralization’ through a three-tier system of local government from village to district Level-Gram Panchayat at village level, Panchayat Samiti at block level and Zilla Parisad at district level -which ultimately came to be known as Panchayati Raj in India. The recommendations of the committee were accepted by the National Development Council (NDC) in January 1958. The NDC did not insist on a single rigid pattern of panchayat raj system throughout the country but left it to the states to evolve their own patterns suitable to local conditions. But the basic principles and broad fundamentals of democratic decentralization remained identical throughout the country. Thus, the Panchayati Raj system came into existence in 1959 with two basic objectives. These were (1) democratic decentralization and (2) local participation in planned programmes. The new system of Panchayat Raj Institutions was first adopted in Rajasthan and Andhra Pradesh in 1959, followed by Assam, Tamil Nadu and Karnataka in 1960, Maharashtra in 1962, and Gujarat and West Bengal in 1963 and 1964 respectively. By the mid-sixties, the hype to strengthen the Panchayati Raj Institutions (PRIs) gave way to a growing tendency of centralization and the PRIs descended to ground zero. To revive the working of PRIs, the Janata Government in 1977 appointed a committee headed by Ashok Mehta to study the functioning of PRIs and to suggest measures for improvement. The committee suggested a minor change in the Balwantray Mehta Scheme. Mehta (1978), in the Report of the Committee of Panchayati Raj Institutions (PRIs) identified three phases of Panchayati Raj in India

Agriculture Technology Management Agency (ATMA)

Extension Reforms were introduced during 2005-06 by the Department of Agriculture & Cooperation (DAC), Ministry of Agriculture, Government of India as a major intervention in addressing the constraints as observed in T & V and post T & V system by making the extension system farmer driven and farmer accountable through process and institutional reforms mechanism. The institutional mechanism in the form of Agricultural Technology Management Agency (ATMA) at district level was pilot tested under Innovations in Technology Dissemination (ITD) component of National Agricultural

Technology Project (NATP) in seven states viz. Andhra Pradesh, Bihar, Himachal Pradesh, Jharkhand, Maharashtra, Orissa and Punjab covering 4 districts in each State from 1998 to 2004. The key features of reforms are:

1.1. FYM compost

Decomposed mixture of dung and urine of farm animals along with litter and left over materials from roughages or fodder fed to the cattle.

Farmyard manure contains 0.5% N, 0.2% P₂O₅ and 0.5% K₂O.

Urine contains one per cent nitrogen and 1.35% potassium.

10 to 20 t/ha is applied, but more than 20 t/ha is applied to fodder grasses and vegetables like potato, tomato, sweet potato, carrot, radish, onion etc., respond well to the farmyard manure.

Crops like sugarcane, rice, oranges, banana, mango and coconut respond good to FYM.

10.1. Heterosis

Occurrence of a genetically superior offspring from mixing the genes of its parents.

Superiority of F₁ hybrids over its both parents in terms of yield and vigour.

8.1. Definition

Managing pests by combining biological, cultural, physical and chemical tools to minimize economic, health, and environmental risks.

8.1. Comparative advantage principle

Different areas or regions or farmers will tend to produce those products for which they have greatest comparative and not just absolute advantage.

Due to an extension and application of principles of specialization and diversification.

Each farm or region produces those crops or raises that livestock which it can grow more profitably

For example, farmers in Tamil Nadu specialize in sugarcane cultivation and those in Punjab specialize in paddy cultivation.

2.1. Radio

A popular communication medium

2.1.1. Historic features

In India, Madras Presidency Club pioneered radio broadcasting in 1924.

Due to financial difficulties, gave it up in 1927.

In 1927, businessmen in Bombay started Indian broadcasting Company with stations at Bombay and Calcutta.

But, failed in 1930.

Different type of mycotoxins commonly present in different feed and fodder crops are produced by mould during cultivation and storage and are specific to certain region according to climatic and environmental conditions. Most of the toxins produced in crops are consumed when fed to animals. Among the mycotoxins, aflatoxin B-1 is present in highest concentration which enters rumen following ingestion of aflatoxin contaminated feed stuffs. In the rumen, AFB-1 is degraded into aflatoxicol and the remaining portion of the aflatoxin is absorbed in the digestive tract by passive diffusion and metabolized in the liver into aflatoxin M-1 (Kuilman et al., 1998). AFM-1 circulates in the blood as a stable compound until excreted in milk, urine and bile. The following are the sources of AFM-1 contamination in milk and milk products and it occurs through two modes of contamination viz., indirect contamination and direct contamination.

1.1 General

Food is basic necessity for the survival of human beings. It is derived from agriculture which traps and transfers solar energy in chemical energy in the form of biomass and end products are processed and utilized for food, feed, fibre, fertilizer, and fuel. Indian’s economic security continues to be foreseen upon agricultural sector. Agriculture supports 52 per cent of population, as against about 75 per cent at the time of dependence. Despite the focus on industrialization, agriculture remains a dominant sector of the Indian economy both in terms of contribution to Gross Domestic Product (GDP) as well as a source of employment to millions across the country. India occupies a leading position in global trade of agricultural products. However, its total agricultural export basket accounts for a little over 2.15 per cent of the world agricultural trade. The major export destinations are USA, Saudi Arabia, Iran, Nepal and Bangladesh. Among agricultural commodities, basmati rice, spices, oil meals, sugar, cotton and castor oil have been leading export commodities.

Agriculture is an essential ingredient in overall development of India economic. The history of Indian agriculture in dates back to Indus Valley Civilization and even before that in some places of Southern India. India ranks second worldwide in farm outputs.

On the eve of Independence, 70 per cent of India’s nation income was from agricultural sector. Before 1947, over 85 per cent of country’s population lives in villages where livelihood completely depended on agriculture, which contributed over 95per cent of country’s income. Agricultural sector was most important sector in Indian economy facing massive stagnation and continuous determination. In the present context, around 60 – 70 per cent of Indian population directly or indirectly depends upon the agricultural sector and currently it contributes to 16 per cent of the Indian gross domestic product.

4.1 Introduction

In the modern era, agricultural productivity seems to have reached a maximum production due to the easy availability of fertilizers and pesticides/insecticide, which are used to improve crop productivity. Excess uses of these products and unawareness about field constraints can decrease the crop productivity and endanger the environmental balance in the cultivation area. Therefore, there is an urgent need to improve agricultural system and efficient utilization of these resources for profitable and environmentally sustainable agriculture.

Government has also an emphasis on effective and efficient use of available resources and farmers are also adopting more scientific approach during crop production such as remote sensing, global positioning system, and new equipment to make their agricultural operation more precise.

Precision agriculture is one of the many advanced farming approaches that make production more efficient. It is basically an approach of farm management with the help of information technology to confirm that the cultivated crops and soil receive desire input for optimum health and productivity. In other words, precision agriculture utilizes different tools and technologies to identify infield soil and crop variability for improving farming practices and optimizing agronomic inputs. To reduce dependency on excessive use of chemical inputs in agriculture, several technologies have been applied to make agricultural products safer and to lower their adverse impacts on the environment and human beings, a goal that is consistent with sustainable agriculture. Precision agriculture has emerged as a valuable component of the framework to achieve this goal. Further, Pierce and Nowak define the precision farming that, the application of technologies and principles to manage spatial and temporal variability associated with all aspects of agricultural production for improving crop performance and environmental quality. Precision agriculture is the combination of many different elements working together in a synchronised way with the help of Geographic Information System (GIS) as shown in Fig 4.1. Precision agriculture is basically an information technology based agricultural management system. In this modern management system, Geography information system (GIS) based analysis is extensively used to get land and crop related data accurately and timely, which help farming community to take correct decision .

6.1 Introduction

Aquaponics represents the relationship between water, aquatic life, bacteria, nutrient dynamics and plants, which grow together in waterways all over the world. Taking cues from nature, aquaponics harnesses the power of bio-integrating these individual components: exchanging the waste by-product from the fish as a food for the bacteria, to be converted into a perfect fertilizer for the plants, to return the water in a clean and safe form to the fish. Just like mother nature does in every aquatic ecosystem.

Aquaponics is basically a combination of aquaculture and hydroponics plant production in a close-loop water system where both vegetables and fish grow simultaneously. This is a closed-loop system and considered as highly efficient, produce more food compared to the traditional farming system. Importantly, it has virtually no waste and with double purpose, aquaponics farming might be an economical viable solution to the low provision of fish and vegetable in some countries. In many cases, aquaponics is advertised as a form of sustainable agriculture because it is water efficient, and has fewer environmental impacts than some forms of aquaculture. That is why, aquaponics is considered as super sustainable and highly efficient because of the healthy symbiotic relationships among the plants, fish and nitrogen-fixing bacteria as illustrated in Fig 6.1. As fish excrete into the water, the water is then pumped up to the plant beds, and bacteria break down the fish excrement so the plants can absorb it.

Aquaponics farming is quite different than hydroponics farming. As discussed in previous chapter, hydroponics is the process of growing plants in a soilless medium where nutrients are added to the water for the plants to absorb. Such systems are not as sustainable and viable as aquaponics because they require the addition of other supplemental nutrients to get desired plants growth. The quality of water decline with time and require proper disposal otherwise, it will contaminate water streams and other water sources. On the other hand, aquaponics incorporates fish to provide the natural fertilizers and nutrients plants need. This simple addition, eliminates the need to add “food” for plants. Best of all, aquaponics has a built in self-cleaning and filtration system that returns clean water to the fish. Aquaponics farming system can be more productive and economically feasible where land and water are limited. No doubt, aquaponics is complicated and requires considerable start-up costs. The production of fish and vegetables is the most visible output of aquaponics farming units. It is essential to understand that aquaponics is the management of a complete ecosystem that includes three major groups of organisms: fish, plants and bacteria.

8.1 Introduction

In the modern world, the most elementary desire of every common man is to have sufficient food and mental peace. With the increasing world population, pressure on both peace and availability of food are continuously increasing. Advancing agricultural research can explore a possibility to feed to all living beings. Agricultural crops are highly susceptible to climatic conditions and crop productivity which are mainly influenced by extreme weather conditions; including temperature and water availability. In open field conditions, during long dry weather condition, soil moisture reduces and increases the transpiration.

Plants are very important to all forms of life on the earth because they consume carbon dioxide from the atmosphere and produce oxygen. In addition, plants make up the base of the food web. Basically, plants need five things in order to grow and these are: sunlight, proper temperature, moisture, air and nutrients. These five things should be provided by the natural or artificial environments where the plants live. If any of these elements are missing, they can limit plant growth. If any environmental factor is less than ideal, it limits the plant›s growth. People began putting plants indoor to avoid the damage from cold weather and this practice led to development of greenhouse. With the improvement in living standard and upgradation in agricultural technologies, off seasoned cultivation is also possible by providing desired artificial environmental conditions. The environmental stress weakens a plant and makes it more susceptible to disease or insect attack. In the modern engineering era, plant production systems have become more sophisticated. The desired climatic condition to grow plants and its control have changed from manual to automated digital operations and control computers have become faster and more capable.

Environmental control techniques are essential for protected cultivation and are not only for greenhouse’s cultivation but are also applicable to tissue culture and space farming as well. Environmental control in the present protected crop cultivation practices has been profusely supported by computer and sensor developments which is sometimes aslo called controlled environment agriculture.

9.1 Introduction

The increase in world’s population and respective food demand has brought the global concern. The climate change alone has put a tremendous burden on the farming communities, and has become the major challenge to feed the burgeoning population. It has been estimated that by the end of the year 2050, the global population will be around 10 billion, meanwhile, the food demand will also be increased by 70-100 %. The traditional method of agricultural practices are not sufficient enough to meet the rising food demand. Therefore, to meet the increasing food demand, agriculture is intensified by the use of chemical fertilizer, pesticides, herbicides, which deteriorat the soil health. Thus, new automated/ mechanised systems have been introduced into the agriculture sector to ensure precision farming. These systems are quick in action, and satisfing the requirements along with generation of billions of employment worldwide. In a developing country like India, 65-70 per cent of the total population resides in rural areas, of which, most of the households are dependent on agriculture. The agriculture sector in India accounts for 18 per cent of the country’s GDP, and provide employment to 50 per cent of the total work force. The agriculture sector is one of the most sensitive sectors of Indian economy which supports all other sectors, and spreading its benefit to the far-reaching areas. Therefore, it becomes important for the developing country like India to develop agriculture sector to boost-up the rural economy.

With the advent of technology, a rapid transformation has been occurred in various industries, while agriculture remains the least digitized. Though, the application of aircraft/ drones in agriculture for fertilizer/ pesticides applications, image capturing, access to real-time quality data has adopted in some developed countries like Australia, USA, Japan, and some of the European countries. Moreover, these unmanned aerial vehicles could provide data of soil health, monitor crop health, assist in irrigation scheduling, yield estimation, and weather data analysis too. However, such development in agriculture is still lacking in developing countries. The agriculture development in the modern era could be done by taking the biological information and agricultural knowledge through integration of modern agriculture information technology with traditional agricultural practices. These knowledge integrations with mobile internet, cloud computing, and machine learning could enable to control the agricultural production system over stressed climate condition easily. Thus, Artificial Intelligence (AI), which is a sort of machine intelligence, an inbuilt set of programme and algorithms similar to the human brain in the current world is gaining more attention in agricultural application for precision farming.

Abstract

Phosphorus is the second important key element after nitrogen as a mineral nutrient in terms of quantitative plant requirement. Although abundant in soils, in both organic and inorganic forms, its availability is restricted as it occurs mostly in insoluble forms. The dynamics of phosphorus in soil is closely related to the dynamics of the biological cycle in which microorganisms play a central role. They also participate in the cycles of the most important macro and microelements such as phosphorus besides their major role in the decomposition of plant residues, creation of humus and maintenance of stable soil structure. Microorganisms affect the amount of phosphorus accessible to plants by means of mineralization of organic phosphorus compounds, immobilization of available phosphorus and solubilization of non-soluble phosphorus minerals such as tricalcium phosphate. Mineralization is catalyzed by microbiological enzymes phosphatases secreted by a diverse group of bacteria, fungi and other groups of microorganisms. Organic phosphorus mineralization in soil depends on several soil and environmental factors such as temperature, pH, soil moisture, degree of aeration. In this chapter the major emphasis is given on the transformation of P through microbiologically involving different enzymes and also the microorganisms involved in the process. Emphasis is also given on the factors that have profound influence on the microbial transformation of P in soil and ultimately making it available for plant uptake. This chapter also focuses on the mechanism of P solubilization, role of various phosphatases, impact of various factors on P solubilization and potential for application of this knowledge in managing a sustainable environmental system.

Abstract

Human milk is the dynamic fluid provides initial and essential nutrients to the neonates and play key role in development and growth of infant gut microflora, nerve system, immunity system and other organs. Composition of human milk varies with number of factors from geographical location, individual habits, stage and period of lactation to mature or pre mature born of infant. Each component and its bioavailability in human milk plays specific function in infant nourishment. Protein and non-protein nitrogenous compounds of milk provides essential bioactive component required for preventing infants form many diseases and develop immunity. Nucleotides involve in many enzymatic and metabolic activities. Milk contains 3.0 to 5.0% fat act as a major source of energy consisting of larger portion of triglycerides. Essential fatty acid of milk important for nerve system development in infant. Additionally, fat soluble vitamins plays in sight and immune development for new-born. A Human Milk Oligosaccharide is natural prebiotic present in human milk which helps in growth of bifidus bacteria and prevent respiratory tract infection in infants. Furthermore, micro components like vitamins, mineral, enzymes involved in various essential activity lead to healthy infant.

Introduction

Agriculture is that the back-bone of the economics of eveloping country likes India. It’s additionally the most “culture” for rural families even nowadays agriculture and allied activities build the one largest contribution to gross domestic product. Female are mother of the race and liaison between generations. Female’s role in agriculture and agricultural heritage described and recognized by the United Nations Organization (UNO) that has sustained the expansion of society wrought the long run of states. Within the rising advanced social state of affairs female have a role to play. Rural females are the foremost vital productive hands within the economy of majority of the developing nations together with India. Female are concerned all told the aspects of agriculture. India incorporates a preponderantly rural economy. Seventieth of her population is rural; of these households, have interaction in agriculture as their main supply of financial gain. It’s forever been India’s most vital economic sector. Female plays a significant role during this vital agricultural sector, as a result of it’s for the most part a ménage enterprise. Female in India are major producers of food in terms important, volume and variety of hours worked. Nearly 63% of all economically active men are engaged in agriculture as compared to seventy eight per cent of female. Nearly 50% of rural female employees are classified as agricultural labourers and thirty seventh as cultivators. Concerning 70% of farm work was performed by women. In several countries, women play a major and crucial role in agricultural development and agricultural allied fields together with, main crop production, live-stock production, gardening, post-harvesting operations, agro/social biology, fishing etc. as it is evident; it’s a reality long taken without any consideration however unheeded since ages. Hence, here a try has been created (i) to review the role of female in agriculture and changes in their position at small level, that’s village level (ii) to review the gender discrimination in land, labour and wage market.

Ornamental fish breeding and trade provide excellent opportunities for employment and income generation. One of the most critical determinants of the success of the trade is the problem of delivering a quality product to the market. The know-how of collection, critical handling, packaging methods are essential for serving the successful transport of live tropical fish to their final destination. However, a major impediment in expanding the trade of indigenous fishes is the poor roads/communication from most of the collection/landing centres to the town, non-availability of oxygen packaging at remote collection centres, difficulties in transportation of the collected fishes to the agent/stockist. Transportation of live fish and shellfish from areas of collection to destination or from areas of farming to the destination is an important activity of ornamental fish industry.

Proper collection, packing and transportation may help in increasing trade to a greater extent. Ornamental fishes destined for marketing, both domestic and export, have to use modern post-harvest technology or modifications of the current post-harvest technology to improve the post-harvest and post-shipment survival that is critical to the industry. It is in this context that the significance of packing and transport come into the picture. To overcome the problem of high mortality of fish species at different stages during transportation, it becomes essential to evaluate the most suitable and ideal condition for transportation. At present, the mortality rate during fish catching, collection, transportation is very high. The claim by the importers due to DOA (Death on Arrival) from India is on the higher side compared to the consignments from other developing countries. This is due to the lack of appropriate technology for fish packing & transportation/ shipment. Similarly, since the airfreight charges are very high, the exporters have no idea of the optimum number of a particular live fish to be packed in a container to reduce transportation cost. Such information is lacking for Indian fishes. The success of ornamental fish transportation depends on the following steps:

1. Choose the most appropriate option with a tick mark

i) Floating plants are required for breeding

a) Guppies

b) Angel fish

c) Swordtail

d) Gourami

ii) Breeding traps are generally used for

a) Egg-scatters

b) Egg-depositors

c) Livebearers

d) Nest-builders

Soil classification, or soil taxonomy as it is called, is grouping of soils in an orderly and logical manner based on soil properties (differentiating characters) for the purpose of studying and identifying them. The following are the purpose of soil classification:

To organize our knowledge of soils

To bring out and understand the relationships among the soils

To remember the properties of soils

To learn new relationships and principles in different soil groups

The types of crops and the practices used to grow them and the sequence in which they are grown altogether refers to cropping system. It comprises of all components required for the crop production and their relationships with the environment. Traditionally the cropping systems aim at maximizing the per unit area productivity, which can be done by growing improved high yielding varieties, by adequate and scientific crop management practices and by increasing cropping intensities with the help of different cropping patterns.

In today’s world cropping system should produce more, at the same time the practices should be ecologically and environmentally sustainable. There should be efficient utilization of land and water. It should be designed to conserve soil, soil moisture and improve soil resilience.

Introduction

Agriculture is the backbone of Indian economy. Good harvest helps in moving the economy in the right direction. The agriculture sector accounts for 17% of US$ 2.6 trillion economy of India (Anonymous, 2019a) and employs 54.6% of the country’s workforce (Anonymous, 2019b). India occupies first place in the production of pulses, jute and milk, and second place in rice, wheat, cotton, sugarcane, vegetables and fruits (FAO STAT, 2020). The agriculture export constitutes a fifth of total exports made by India and self-reliance in agriculture is required to become an economic superpower. The green revolution has paved the way from begging bowl to overflowing granaries in our country. The overall food production has increased from 52 MT in 1950-51 to 295 MT in 2019-20, which is a phenomenal growth of more than five times in seven decades span. Of the several factors that influenced the sea change in agriculture production and productivity, the quality seed of improved varieties occupies a crucial position. The green revolution was ushered in by the import of 18000 tonnes of seed of high yielding wheat varieties Lerma Rojo and Sonara 64 and rice variety IR-8. Till today, the quality seed alone contributes to 15-20% of total production (Chauhan et al., 2015), indicating its importance in agricultural production of the country. The problematic global scenarios like economic recession, climate change, water scarcity, population explosion, pollution or new pandemics drives the states to be more self-reliant. To be self-reliant is not to be altogether “self-contained”. We should be opened for the best material available anywhere in the world, and simultaneously we should develop our infrastructure and industry to cater to the needs of our population as well as export to other countries. Seed sector is one of the potential areas for boosting self-reliance as well as has a lot of export potential. The government push for self-reliance under the present COVID-19 pandemic situation by infusing INR one lakh crore as agricultural infrastructure fund that will help in developing several start-ups. The success of this movement mainly depends on innovations in every sector, including the seed sector and simultaneously, there is a need to extend it to the regulatory mechanisms. This chapter will discuss the possible areas of innovations that are already in the pipeline and those to be targeted in the areas of seed production, quality assurance, marketing and regulation along with policy interventions needed to boost the seed sector.

Introduction

Surging food demand and shrinking land resources to produce more from the limited natural resources like soil and water is poised to environmental degradation. Increased production must be achieved mainly by increasing crop productivity per unit area while sustaining the environment and enhanced input use efficiency. Agricultural production systems are increasingly under pressure to adapt decision-making process to be make more informed and efficient use of irrigation water, fertilizers and pesticides. Adverse effects of climate change are added challenges to agricultural productivity. Efficient crop management strategies to improve resource use efficiency and reduce crop losses are vital issues to be taken care for a sustainable sustainably enhanced production system. Genetic improvement approaches involving high throughput phenotyping and genomics-assisted breeding enhancing resource use efficiency, stress tolerance, yield has become imperative. Precise crop health monitoring is one of the keys to the modern production system. Obviously, disease forecasting and surveillance systems are in great demand to adopt precise management against the losses caused by diseases. Predicting disease risk at regional and global scales is of great interest for on-farm management and for assessment of agricultural policies and practices.

Historical Perspective of Agricultural Education Policy in India

Pre-Independence Era

During the reign of the British Crown, vocational education and training suffered a great setback and there was a lack of emphasis on agricultural education, even though the Indian economy, to a great extent, depended on agriculture. In 1901, only five institutions were imparting theoretical and practical instruction in agriculture, but that education was not used in extension or fieldwork—it served only as an opening for government white-collar jobs (Crane, 1965).

Post-Independence Era

Prior to the establishment of agricultural universities, university-level education in agriculture, animal science, horticulture, agricultural engineering, and allied subjects were largely conducted by colleges affiliated with general universities that had no special commitment to the farming community. The University Education Commission of 1947, among other things, examined the state of agricultural education in India. The report of this Commission emphasized the need for having what was termed “Rural Universities.” In 1954, the First Joint Indo-American Team on Agricultural Research and Education fully endorsed the recommendations of the University Education Commission and strongly recommended the immediate establishment of agricultural universities in a few selected states. The U.S. agricultural advisors who began to arrive in India in the early 1950s were products of the land-grant university system, and many of them naturally believed India could benefit by creating a similar system (Goldsmith, 1988). The Government of India accepted this recommendation and the first agricultural university in Uttar Pradesh now named as Govind Ballab Pant of Agriculture & Technology was established in 1960, patterned on the land-grant university model of the United States. This was a significant turning point in the history of agricultural education in India. The Second Joint Indo-American Commission (1959) reiterated the recommendations of the First and recommended that at least one agricultural university be established in each state. Agricultural universities have now been established in 21 of the 28 states and the concept of the agricultural university now forms an essential part of the national policy on education.

Japanese plum (Prunus salicina) is widely grown in hill and to a limited scale in the plains of north-western India. Although the fruit quality of plums produced in subtropical is poor however, it fetches high process in the market because of it early availability. Its availability in market at a time when the competition from other fruits is less. It is known as Japanese plum due to its cultivation in Japan from where cultivars spread to other places. At present, plum is cultivated in all temperate climate countries of the world. Plums are a familiar part of our diets. These sweet, fleshy fruit are a common sight in super market shelves. Prunus domestica, the European plum, is an important crop that has been cultivated in Europe for over 2,000 years. When the early European settlers landed on the shores of North America, they found various kinds of native plums scattered throughout the countryside, all of which were found to be of inferior quality. Until the 19th century, most plum cultivation in the United States was confined to the European varieties that were brought overseas. Today, new plum hybrids of native and Asian species have been developed for fresh market consumption, but Prunus domestica remains the prime source for processing plums. Depending on the variety, these plums can be good for either canning, drying as prunes, for culinary uses, or, in lesser amounts, eaten fresh.

Ornamental horticulture consists of floriculture and landscape horticulture. Each is concerned with growing and marketing of plants used to beautify the outdoor environment and with the associated activities of flower arrangements and landscape designs. Ornamental plants provide comfort and peace in our everyday lives. Floriculture is a dynamic, global, fast growing industry comprises of cultivation and trade of cut flowers, loose flowers, potted plants, foliage plants, dried flowers and value added products etc and is becoming popular in both domestic and export markets (Rikken, 2010). In the recent years, ornamental horticulture has emerged as a profitable agri-business in India due to improved living standards and growing consciousness among the citizens to live in environment friendly ambiance. Now-a- days this activity has assumed the commercial status with great potential for generating gainful self-employment among small and marginal farmers. Globalization of the Indian economy and subsequent liberalization of the Seed Act paved the way for the advent of protected cultivation of flowers in the country resulting in increase the production of quality floricultural products witnessing their presence in the international flower markets. The production and trade of floriculture has exhibited considerable increase consistently over the last decade in the country.

Flowers and ornamental plants have been associated with mankind since time immemorial, as they have been used for religious offerings and other social ceremonies. Loose flowers are mostly grown for worship, garland making and decoration. Cut flowers like rose, chrysanthemum, carnation, gerbera, anthurium, orchids and lily are mostly grown for export purposes. Some of the flowers are also edible with their nutritional value e.g. Dahlia tubers, lily, tapioca etc., mainly their roots are rich in starch and even dahlia roots are considered good to cure the cancer.

A garden is a place where ornamental plants are grown to put on display various forms of plant life which are purposely intended for ornamental or practical use or both. Now days we often use the term landscape gardening, Landscape architecture and Landscape design. Landscape gardening can be defined as arrangements of trees, shrubs, climbers and variety of other plants in concert with the building, walks, drives, artificial and natural features for the use of humanity while Landscape architecture is the art of arranging land and landscape for human use convenience and enjoyment. A good landscape design determines the characters of objectsto serve a certain purpose known in advance.

The subject garden planning is diverse and complex and very difficult to symbolize all ideas of wholeness. In modern living consciousness of interior decoration including furniture,woodwork,wall furnishing, carpets painting also needs careful setting and the services of specialist are considered necessary for this purpose. In order to achieve a rewarding result a garden should be designed carefully as it is semi-permanent feature and frequent change in design is not possible.

Principles of design steer designers to organize elements for a visually pleasant landscape. A melodious composition can be achieved through the principles of proportion, repetition, order and unity which are alllinked and application of one principle assists to achieve the others. By using these principles, two important concepts in garden design i.e. physical and psychological comfort can be achieved. Landscape that has order and repetition creates more psychologically comfortable feeling. Psychological comfort is also affected by the sense of satisfaction that a spectator perceives from a harmonious landscape. Users feel more physically comfortable and secure in a landscape with proportions compatible to human scale. Garden design combines the aesthetic beauty, artistic knowledge and at least the principles of gardening. In order to layout good garden some fundamental principles to be followed

Annual flowers are a cluster of herbaceous plants which grow from seeds, produce flowers, set seeds and complete their life-cycle within one year or one season. They offer a gorgeous display of colours within the garden. Whether it is a small homemade garden or a giant public garden, it is incomplete without beds of annual flowers. They enhance the ornamental value of a garden within a small span of time. At their blooming time, one feels elated when rainbows of colours appearin the garden.

Classification of Annuals

Flowering annuals are grown in beds and pots. They’re used for several purposes in the garden. In beds, they are grown individually with or without perennial plants in borders. They are developed in hanging baskets, window boxes or rock gardens, for training on walls and trellises and for planting in the form of edges, borders or ground covers. Dried flowers of some annuals are similarly used for interior decoration. Some annuals provide sweet fragrance.

1. Based on season: the annual flowers are divided into 3 groups—winter, summer and rainy season.

Orchid is a valuable flowering plant belongs to family Orchidaceae. It is considered that the family recognise for maximum number species ranged between17,000 and 35,000 worldwide (Garay 1960; Willis 1973). The word orchid is derived from a Greek word orchis for testicle because of the shape of the root tubers in some species of genus Orchis. India is a reservoir of 1300 orchid species from 184 genera, accounts for nearly 7 per cent of worlds orchids genetic diversity (Arora, 1983; Rampal and Nagrare, 2006) and 1150 species belonging to 164 genera (Satish Kumar and Manilal, 1994) of which about 800 species are found in the North Eastern region of the country (Nagaraju et al., 2006). Apart from species, more than one lakh hybrids developed in orchids. It is found all over the world from tropical to temperate and even alpine region. People always think that orchids are epiphytic only but it is not. It can grow in soil as terrestrial, on tree trunk (epiphytic) and on dead organic matter (saprophytes) and on rocks (lithophytes). Orchids produce unique flowers, affluent for their uniqueness in shape, size and colour, exquisitely attractive; remain fresh condition for long period of time in comparison to other flowers. Vase life of its flowers varied among species and hybrids ranged up to 40-45 days. Orchids are cultivated for trade of orchid species, cut-flowers, potted plants, flower basket, bouquet, stage decoration in high profile meets and functions and also used in many other value-added products (Kuehnle 2007). Many orchid species are used as food like Cymbidium hookerianum, Dendrobium chrysotoxum, D. kingianum, D. cathenatum and many more (Singh et al., 2016), spices (Vanilla planifolia and V. pompona) and medicinal uses (Dactylorhiza hatagirea, Flickingeria macraei, Vanda tessellata and Dendrobium macraei as reported by Ram Pal et al., 2020). The most popular and commercially cultivated genera are: Cymbidium, Dendrobium, Oncidium, Phalaenopsis, Vanda, Paphiopedilum, Mokara, Arundina, Paphiopedilum, Ascocenda and Cattleya in the country and even in the world.

Anthurium is commonly known as anthurium/tail flower/oilcloth flower (Anthurium andraeanum) and flamingo flower/flame plant (Anthurium scherzerianum). The word anthurium is derived from two Greek words viz, anthos meaning flower and aura meaning tail, referring to the spadix. Anthurium plants were growing undisturbed for hundreds of centuries in the rainforests of South America. Samuel Damon, a businessman and politician in the Kingdom of Hawaii brought one species out of hundreds of species of anthurium to Hawaii in 1889 for cultivation in his garden. The plants were introduced by various people in their gardens from Samuel Damon’s garden. It is a tropical ornamental plant valued for its flowers and unusually attractive foliage. In India, it is grown commercially in Assam, Kerala, Tamil Nadu, Karnataka, Sikkim, West Bengal, Meghalaya and Maharashtra. In India, total anthurium flower production is 3230 tonnes with Assam producing highest anthurium production of 2050 tonnes followed by Meghalaya 740 tonnes (Seemanthini and Chandrashekar, 2018). Major markets in the world for per capita consumption of anthurium flowers are Europe (47.80%), United States of America (21.80%) and Japan (16.80%) (Misra and Misra, 2017). In anthurium, various ploidy levels exist like diploid (Anthurium andraeanum and A. hookeri), triploid (A. scandens) and tetraploid (A. digitatum and A. wallisii). Basic chromosome number varies in different species of Anthurium. Most of the Anthurium species have 2n = 30 chromosomes while in some polyploids, it is 2n = 60. However, a few species have 2n = 20 to 124 chromosomes (Petersen, 1989). In Anthurium andraeanum, somatic chromosome number has been found as 2n = 30 + 2B and this species has high percentage of meiotic abnormalities and karyotype differences suggesting its hybrid origin. Anthurium plants need medium care and reach up to a height of 45-50 cm bearing pale white to yellow coloured flowers with orange to red coloured bracts.

Dahlia (Dahlia variabilis Desf., family: Asteraceae, origin: Mexico) is regarded as a premium specialty cut flower besides its utilization for garden decoration and growing as a potted flowering plant. The dahlia flower symbolizes elegance, inner strength, creativity and dignity. It is herbaceous rooted perennial valued for their majestic and attractive display of colourful spectacular flowers. The generic name “Dahlia” was coined by Swedish botanist “Andreas Dahl”. Dahlia was introduced in India during 1857 under the auspices of the “Agri-Horticultural Society of India”, Calcutta. Dahlia exhibit wide range of flower from and size ranging from miniatures (less than 2.5 cm across), to giant (more than 40 cm in diameter). Dahlia flowers profusely and its easy cultivation have made these very popular worldwide. The commercial value of this crop has been exploited in certain countries only. The Netherlands is claimed to be the largest producer of tuberous rooted dahlias. Other countries cultivating Dahlia as a specialty cut flower are Japan, France, South Africa, the U. K., Italy, Germany and the United States. The commercial cultivation of dahlia in Indian subcontinent is limited to hills and plains of Eastern India (Misra and Misra, 2017).

Holland takes the lead in dahlia bulb production cultivation neeary 400 ha, followed by France and Chile. There are 41 international associations concerned with the cultivation and spreading awareness about dahlia as a potential specialty cut flower and flowering potted perennial. Societies such as National Dahlia Society in the UK, the American Dahlia Society (ADS), other groups of New Zealand in European countries, France and Germany have been maintaining Dahlia germplasm for developing novel flower colour and breeding dahlias for their uniform and profuse flowering, longer flower duration, stem sturdiness and longer vase life.

Jasmines constitute a group of traditional flower crops which are commercially grown for their fragrant flowers and essential oil production. There are trailing, climbing, and erect growing species and cultivars in the genus Jasminum. The genus Jasminum comprises of more than 200 species which are known to occur in different tropical and subtropical regions of the world. The countries growing Jasmines on a commercial scale are India, France, Italy, Morocco, Algeria, North Africa, Egypt and Spain. More than 80 Jasminum species are found in India, of which only four species viz., Jasminum sambac (Mogra / Gundumalli), Jasminum auriculatum (Jui / Mullai), Jasminum multiflorum syn Jasminum pubescens (Kunda / Kakda) and Jasminum grandiflorum (Jai / Pitchi) are widely used for commercial cultivation. Jasmines are commercially grown in many parts of the country as a dry land crop. The leading states in jasmine production are South Indian states like Tamil Nadu, Karnataka and Andhra Pradesh. In India, the commercial cultivation of jasmines are popular in Athoor, Coimbatore, Dharampuri, Dindigul, Erode, Krishnagiri, Madurai, Nilakottai, Periakulam, Salem, Thiruchirapalli, Thirunelveli, Thiruvallur, Tirumanagalam, Vellore, Virudhunagar etc. in Tamil Nadu; Bangalore, Bellary, Kolar, Mysore, Shimoga, Tumkur etc. in Karnataka ; Hyderabad, Khammam, Mahbubnagar, Mancherial, Ranga Reddy, Sangareddy, Vikarabad, Warangal Rural, Yadadri etc. in Telangana; Anantapur, Chittoor, Cuddapah, East Godavari, Guntur, Krishna, Kurnool, Nellore, Prakasam, West Godavari etc. in Andhra Pradesh; Ahmednagar, Aurangabad, Pune, Sangli etc. in Maharashtra; Ahmedabad, Anand, Bharuch, Bhavnagar, Kutch, Vadodara etc. in Gujarat; Gazipur, Jaunpur, Kannauj etc. in Uttar Pradesh; Ajmer, Jaipur, Kota, Udaipur etc. in Rajasthan; Panskura Ranaghat etc. in West Bengal; Guwahati, Hoja, Jorhat etc. in Assam ; and parts of Punjab and Delhi. Jasmines contributes markedly to the national economy and it is estimated that annually more than 20 crores worth of jasmine flowers are produced and traded in India and are also exported to countries like Malaysia, Singapore, Sri Lanka, UAE and United States (Safeena et al., 2017).

The Seed Act 1966 was passed by the Indian Parliament on 29th December 1966 and it came into force from 2^nd October, 1969. In addition, Seed Regulation Order was also passed in December 1983. The sole objective of Seed Act and Order has been to ensure that the Indian farmers get good quality seeds of important crops. Important provisions and guidelines for the farmers are given below:

The Act is applicable for the seeds notified by the Central Government from time to time.

Seed quality is regulated at two stages viz. seed production and seed certification. For this purpose, seed testing laboratories and seed certification agencies are to be established in each state. Maharashtra has been the first state to implement this act. Now all the states have implemented this act.

Pumpkin (Cucurbita moschata, 2n = 2x = 40, family Cucurbitaceae, monoecious, cross-pollinated, behaving like self-pollinated crop genetically) is grown globally throughout in the tropical, sub-tropical and temperate regions of both the New and Old World. The term pumpkin is normally applied to the edible fruit of any species of Cucurbita when ripe as a table vegetable or in pie (Whitaker and Robinson, 1986). Squash and pumpkin are the words quite often used interchangeably. However, the term squash or summer squash is commonly used for Cucurbita pepo which is eaten as immature fruit also. The term pumpkin is used generally for all kinds of five cultivated species under the genus Cucurbita but is quite commonly used for C. moschata. Besides C. pepo (summer squash) and C. moschata (winter or baking squash), the other three species under the genus Cucurbita are C. mixta (squash), C. maxima (winter or baking squash), and C. ficifolia (squash, fig-leaf gourd, Malabar gourd).

While compiling statistics FAO clubs squash and gourd together with pumpkin. In 2017, world production of pumpkins (including squash and gourds) was 27 million tons, with China (7.8 million tons from 0.4 million ha) and India (5.0 million tons from 0.5 million ha) accounting for 47% of the total production. Russia, Ukraine, and the United States each produced about one million ton. As per APEDA (The Agricultural and Processed Food Products Export Development Authority), India produced 1.44 million tons of pumpkin which translates into 72000 ha area assuming a productivity of 20 tons/ha during 2015-16. The major states growing pumpkin in India are Orissa, UP, MP and Chhattisgarh. It is clarified that in context of India, pumpkin means C. moschata only although IIHR released a variety of C. maxima under the name Arka Suryamukhi in 1987 (Ram, 2012). However, now it is nowhere to be seen. Fruits of C. pepo (summer squash or zucchini) now can be seen in limited scale in superstores and limited scale cultivation is certainly happening under protected cultivation of this crop in India. Under this chapter, only C. moschata is being dealt with under the term pumpkin. Pumpkin is now becoming popular in India due to its high productivity, nutritive value, good storability, long period of availability and better transportability. It is rich in vitamins particularly precursor of vitamin A and minerals.

Chromatography is the set of laboratory techniques used for the separation of molecular mixtures by developing chromatograms. Chromatogram is a collection of different bands on the chromatographic column. The mixture is dissolved in a fluid called the “mobile phase”, which carries with it another material called the “stationary phase”. The various constituents of the mixture travel at different speeds, causing them to separate. Chroma (colour) and graph in (to write) contribute to the word chromatography, as coined by Mikhail Tswett (1903). Solute moves only when it is in stationary phase. In chromatography, the mobile phase flowing into the column is called eluent, the solution emerging from the column is elute, and the process by which solutes moves and separate is called elution.

This method employs the differences in absorbability of components of mixtures and the differences in the mobility rate. The molecules of a substance which interact strongly with the fixed phase will move slowly through the column whereas substances which do not interact strongly are carried through more rapidly. It is used to separate different substances having similar chemical properties.

Radiation emitted from the radioactive isotopes can be detected and quantified by using several equipments and the details are furnished below:

A. Radiation Detection Devices

1. Electroscope

The electroscope is a simple device comprised of a metal rod with two thin leaves attached to one end. If the electroscope is given a negative charge, the metal leaves will separate from each other. It is the characteristic that makes the electroscope useful as a detection device. A negatively charged electroscope will discharge when ions in the air remove electrons from it, and consequently, a positively charged electroscope will discharge when it takes electrons from the air around it. The rate of discharge of the electroscope is a measure of ions in the air and can be used as a basis of measurement and detection.

Pomegranate (Punicagranatum L.) an extraordinary fruit crop that is cultivated worldwide with dominancy in Mediterranean countries like Morocco, Spain, Egypt, Iran, Afghanistan and Baluchistan since primordial times. Tropical and sub-tropical regions of the Indian sub-continent are the prominent areas under cultivation of this fruit crop. India plays a leading role in pomegranate production with contribution of nearly 50% of global production. The total area under pomegranate is 132 thousand hectare with annual production of 1357 thousand MT in 2014-2015.

Pomegranate (Punica granatum) a deciduous shrub in the family Lythraceae, subfamily Punicoideaeis one of the most adaptive sub-tropical fruit crop. It was introduced in the Indian subcontinent during 15^th century from the Mediterranean region of the globe. India holds the first rank as producer and exporter of pomegranate since last decade. Among the states, Maharashtra is the largest producer of Pomegranate (Punica granatum) in India. Pomegranate have an impressive nutrition profile it contains 7 grams fiber, 3 grams protein, 30% Vitamin C, 36% Vitamin K, 16% Folate and 12% Potassium. It also contains 24 grams of sugar and 144 calories. It contains two important compounds namely Punicalagins and Puninic acid. Along with the above nutritional advantages, it also has immense health benefits right from curing a fatal disease like cancer to remedying arthritis and joint pain. India stands first in the list of Pomegranate producer countries with respect to cultivation area. The states leading in pomegranate production in India are Maharashtra (70.2%), Karnataka (10%), Gujarat (7.4%), Andhra Pradesh (6.7%), Telangana (1.9%), Madhya Pradesh (1.9%), Tamil Nadu (1.0%) and Rajasthan (0.4%) (Source: Horticultural Statistics at Glance, 2015).

Cashew (Anacardium occidentale L.) is an important cash crop and India ranks second to Brazil in production (Shanthi and Vittal, 2012), the incidence of diseases considerable losses in cashew plantations. Cashew nut is a plantation crop that is grown extensively in area along with costal tract of peninsular India. It is the most important export crops and the main source of cash income. Cashews (Anacardium occidentale L.) are a perennial nut crop native to Brazil and belong to the Anacardiaceae family. (Zhongrun and Masawe, 2014). Plans produce numerous pinkish-white flowers and kidney shaped true fruit (nut) in gray-brown shell develops from a fleshy fruit, referred as ‘cashew apple’. The cashew apple is pear shaped and red to yellow in color. The cashew apple is also valued in alcohol fermentation and cashew shell oil for base of paints and water proofing agent. Cashew (Anacardium occidentale L.) is a perennial tree crop, originating from South America from Brazil now widely grown in the tropics. Cashew affected by many biotic and abiotic causes resulting in significant yield losses. Biotic diseases and pests are the most damaging cashew nut yield in terms of quality and quantity. (Freire and Rossetti, 1991; Freire, 1997; Freire and Cardoso, 1995). Many pathogens have now been recorded from seedlings, adult plants and from kernels (Freire, 1996; Freire et al., 1996, 1999).

Major diseases of cashewnut plants are anthracnose (Colletotrichum gloeosporioides), Pestalotia leaf spot (Pestalotia heterocornis), bacterial leaf and nut spot (Xanthomonas citri pv. anacardii), Powdery mildew (Oidium anacardii) Pink Disease or Dieback (Corticium salmonicolor) and gummosis (Lasiodiplodia theobromae) are reported in cashew tree worldwide often considered as the most important diseases causing severe economic damage cashew nut producing countries. According to Sijaona (2013) powdery mildew can cause yield losses ranging from 70 to 100%. In Brazil, anthracnose infection has drastically reduced cashew production by up to 40% in 2000 (Freire et al., 2002).

It is an organized set up to provide micro credit to the rural women on the strength of the group savings without insisting on any collateral security for the purpose of encouraging them to enter in to entrepreneurial activities and for making them enterprising women (Gurumoorthy, 2000).

Puhanzhendi and Badatya (2002) find that the SHG programme has a positive social impact.

Rajamohan (2003) stated that SHG is a medium for the development of saving habit among the women.

Jeyasudha (2004) reported that eradication of poverty and the ushering in of speedy socioeconomic progress is the goal with which the developmental programmes are being implemented through a multipronged strategy, reaching out to the most disadvantaged sections of the society. She placed the concept of rural development at the top of agenda in national policies of developing countries of Asia, Africa and Latin America. The developed countries have also recognized this need and have directed their efforts towards meeting the basic needs of the poorest people in developing countries.

The study is confined to tribal zone of Orissa, especially of Koraput district where tribes account for 49.69% of the district population. The sample SHG were selected from Sadar, Similiguda and Koraput blocks without any prejudice to their performance. At the outset, it is admitted that SHG has created a sensation among the tribes to look forward the development process. The present study ‘SHG in Techno-Economic Empowerment of Tribal Women’ has been conceived to find out inter-play of technological and economic variables that reflect in social status.

Membership status

SHG starts with the philosophy of micro-approach. Small sized group dynamics, available technology and economic opportunity linked with market structure are the perceived objectives to bring change in livelihood system. The study considered the age of SHG, present membership status, rate of discontinuance as the basic factors of SHG in tribal zone.

Introduction

Amaranthus species were grown as the principle grain crop by the Aztecs 5,000 to 7,000 years ago, prior to the disruption ofthe South American civilization by the Spanish Conquistadors. Synonyms such as “mystical grains of the Aztecs,” “super grain of the Aztecs,” and the “golden grain of the Gods” were used to describe the nutritious amaranth grain. Vegetable Amaranthus spp. were and are presently utilized for food from such diverse geographic areas as southwestern United States, China, India, Africa, Nepal, South Pacific Islands, Caribbean, Greece, Italy, and Russia (Stallknecht et. al., 1993). Amaranthus grain is extremely nutritional pseudo-cereal with a higher amount of proteins when compared to true cereals. It is a reasonably well balanced food with functional properties that have been shown to provide medicinal benefits. Amaranth associate underutilized crop and an inexpensive supply of proteins, minerals, vitamin A and C, appears to be a future crop which may substantiate this demand because of its tremendous yield potential and biological process qualities, conjointly recently gained worldwide attention (Topwal, 2019). Amaranth as a unique plant with a long and mysterious history is the obj ect for science and also for business. Its characteristics such as absence of gluten and special composition of oil lead this plant to the position of very important plant for the future. The Advantages of Amaranth for Food Industry: Gluten-free, High-quality protein, Non Food-allergy, Thickening property of amaranth starch. The Advantages of Amaranth oil for Cosmetic Industry: Squalene content has a preserve function for skin and hair against sun and radiation, Available for very sensitive skin, Non- Allergy amaranth oil on skin. Amaranth has a big advantage, because it could be use by two ways-biomass for the bio fuel production and grain for food production (Matusova, 2008). As dyes, the flowers of the ‘Hopi Red Dye’ amaranth were used by the Hopi (a tribe in the western
