Farmyard Manure is the manure prepared by using the mixture of dung and urine soaked litter by microorganisms.

Good farmyard manure is one

Salt affected soils occupy 962.2 m ha globally which accounts for 33% of the arable land. In India 8.373 m ha is affected with salts. Of which 2.359 m ha are alkali soils, 3.829 m ha are saline soils and 2.185 m ha coastal saline soils. Reclamation of these soils provides additional area for food grains production and employment.

Introduction

During the past 60 years, conventional agriculture has become increasingly dependent upon petroleum-based. Chcmically-synthesized fertilizers and pesticides for crop protection and to supply plant nutrients. Certainly, these energy intensive technologies have contributed greatly to this Nation’s agricultural productivity. However, sharply escalating production costs associated with the increasing cost and uncertain availability of energy i.e., fuel and fertilizers, have generated considerable interest in less expensive and more environmentally compatible production alternatives such as organic farming (USDA, 1980). The apparent decline in soil productivity throughout the world from excessive soil erosion, nutrient runoff and loss of soil organic matter; the impairment of environmental quality from sedimentation and pollution of natural waters by agricultural chemicals and the potential hazards to human and animal health and food safety from heavy use of pesticides, have also stimulated interest in organic farming systems of food production.

Use of organic wastes and residues in agriculture

Most countries have traditionally utilized various kinds of organic materials to maintain or improve the fertility, and productivity of their agricultural soils. However, several decades ago organic recycling practices were largely replaced with chemical fertilizers which were applied to high yielding cereal grains that responded best to a high level of fertility and adequate moisture, including irrigation. Soil cultivation was also intensified to improve weed control and seedbed conditions. Consequently, the importance of organic matter to crop production received less emphasis, and its proper use in soil management was neglected, or even forgotten. As a result of this and failure to implement effective soil conservation practices, the agricultural soils in a number of developed and developing countries have undergone serious degradation and decline in productivity.

Introduction

Weeds are the most costly category of agricultural pests, causing more yield losses and added labor costs than either insect pests or crop disease. Weeds are a constant fact of life in annual row crops, vegetables, and other horticultural crops. In India, the manual method of weed control is quite popular and effective. The usage of herbicides in India and elsewhere in the world is increasing due to possible benefits to farmers. At the same time, the continuous use of herbicides of the same weed shift, herbicide resistance in weeds and environmental pollutions. Application of herbicides also kills species of bacteria, fungi and protozoa thereby upsetting the balance of pathogens and beneficial micro organisms. The complexity of these situations has resulted in a need to develop a holistic sustainable eco-friendly weed management programme throughout the farming period (Gnanavel and Natarajan, 2014). Sustainable development of agriculture is concerned about the conservation of land, water, plant and animal genetic resources, is environmentally non-degrading, technically appropriate, economically viable and socially acceptable. Sustainable weed management is the use of weed control methods that are socially acceptable, environmentally benign and cost-effective.

Ber (Ziziphus maruritiana Lam.) is cultivated all over the desert part of the Indian subcontinent for its fresh fruits, which are rich in vitamin C, vitamin A and vitamin B-complex and minerals. It can be successfully cultivated even in the most marginal ecosystems of the subtropics and tropics. Ber or Indian jujube belongs to the genus Zizphus of the family Rhamnaceae and order Rhamnales. Ber is adopted to ecologically poor, drought prone areas, which encounter recurrent crop failures and thereby economic crises. It yields nutritious fruit, rich in vitamins and minerals than apple even in drought years and its cultivation is highly cost effective owing to very low input requirement. Ber cultivation also provides employment for people in different farm operations for production and sale of the produce. In India, Haryana, Punjab, Uttar Pradesh, Rajasthan, Gujarat, Madhya Pradesh, Bihar, Maharashtra, Andhra Pradesh and Tamil Nadu are major ber producing states. The area under cultivation with this fruit is 8.7 lakh ha with an annual production of 8.9 lakh tones in India (Baloda et al., 2012). About 125 varieties of ber are available in India. A few of these varieties are known for taste, size, amount of pulp and higher yields. The cultivars Umran, Kathapal and Gola are the most promising varieties of ber in North India (Azam-Ali et al., 2001).

Nutritive Value

Many people are unaware that the ber is one of the most nutritive fruit, since ber is a common fruit. It is one of the richest sources of vitamin C, next only to aonla and Guava but better than citrus fruit and apple. The fruit pulp contains 13-20% total soluble solids and 0.20-0.80% acidity at fully ripened fruit. Ripe fruit of Umran contains 117 mg ascorbic acid/100 g of pulp. Ber fruit contains β-carotene (vitamin-A) at 81 µg/100 g of fruit, 5.6% sucrose, 1.54% glucose, 2.08% fructose, 1.00% starch and 1.13% total carbohydrates. Due this, so ber is often called the “poor man’s fruit”. Table 1 represent the nutritional composition of different ber varieties.

Tropical fruit tree are important crops which supplement and improve the quality of diet. Many of the species have multi-purpose uses in that they produce non food products such as fuel, timber, fodder, medicines and industrial products for small holders. Harvesting from these trees enable rural people to provide nutrition for a balanced diet and generate income thus alleviate poverty. Tamarind (Tamarindus indica L) can be found throughout much of the tropics, it is grown unattended in backyards, roadsides or waste lands. Tamarind is ideally suited for avenue plantings as a roadsides tree, in and around villages as a multipurpose species for agro-forestry system or as protective firebreaks for forest margins. It is a valuable timber species widely used for making furniture, tool handles, charcoal, oil mills, rice pounders and fuel wood. The leaves are an important source of food and herbal medicine and the edible pulp of ripe fruits is used as a flavouring agent in cooking, soups, jams, chutneys, sauces, pickles etc. The fruit pulp of tamarind forms the “Tamarind of Commerce”. The name tamarind is derived from the Arabic word ‘Tamar-u’l-Hind’ because the dark brown pulp of the fruit was thought to resemble dried dates. It was therefore called the Tamere-hindi or ‘date of India. The production of Tamarind in India was estimated 201000 tonees for year 2017-18 (Horticulture statistics, 2018), India is the world’s largest producer of tamarind products. It is particularly abundant in the India states of Madhya Pradesh, Bihar, Andhra Pradesh, Karnataka, Tamil Nadu and West Bengal. The production in India is mainly concentrated in the drier southern states and the produce is collected by the villagers and sold in the market. In India, the average production of tamarind pods per tree is 175 kg and processed pulp is 70 kg/tree (Kulkarni et al., 1993).

India is today the second largest producer of fruit and vegetable after China with a total annual production of 281.75 million tons in 2017-18. Fruit and vegetables are essential components of the human diet and nutrition constitute. Fruit and vegetable are also element of diversification in agriculture for additional income generating resource and employment generation area. Although India is the largest producer of fruit in the world, the production per capita is only about 100 g per day. Huge losses to the extent of 20 to 40% of the total production are reported due to lack of adequate infrastructure and transportation facilities and higher the transportation cost. Thus the per capita availability of fruits is further reduced to 60 -80 g per day which is almost half the requirement for a balanced diet. The fruit production in India has recorded a growth rate of 3.9%, whereas the fruit processing sector has grown at about 20% per annum. However, the growth rates have been extensively higher for frozen fruits and vegetables (121%) and dehydrated fruits and vegetables (24%).

Fruit and vegetables are mostly seasonal crops but they are demanded by consumers throughout the year. They are very highly perishable in nature, which is difficult to preserve for the longer period of time under ambient storage conditions. The low temperature storage retarded the activity of various biological and biochemical agents of spoilage and provides longer shelf life to the fruit and vegetables The temperature is brought down by taking out the heat with the help of mechanical refrigeration, This system is based on a liquid absorbing heat as it change to a gas. The more common mechanical refrigeration system use a refrigerant such as (Ammonia, Freon etc.,) takes out the heat from the chamber/ store as it is expand. The spoilage agents are microorganism such as (e.g., bacteria, yeast and molds etc.) and larva. Optimum storage temperature for most products is one slightly above the freezing point of the product. Some fruit and vegetables are particularly sensitive to storage temperature are susceptible to called storage disease when stored at temperature below as or above the critical temperature e.g.,

Introduction

Earth’s magnetic field (MF) is a natural component of environment and is an inescapable factor for all living organisms including plants. Earth has an inner core made of molten iron which rotates at a fairly high speed creating a magnetic field just like a dynamo. This Geo Magnetic Field (GMF) extends from the earth’s interior into outer space. It interacts with the solar wind, which is actually a stream of charged particles emanating from the sun. As earth is engulfed in a GMF, all living organisms, both plants, animals and all biological processes are under its influence. However, local differences in strength and direction of the geomagnetic field have been detected. The vertical component of GMF is maximum at the magnetic poles, which is around 67 μT, and the horizontal component is zero there. Conversely, at the magnetic equator the vertical component is zero and the horizontal component is maximum, about 33 μT (Kobayashi et al., 2004).

Turbulent flows of the fluid metallic inner core of earth mainly contribute to GMF and the effect of external MFs located in the ionosphere and the magnetosphere is very meagre (Qamili et al., 2013). As GMF extends beyond the earth’s surface it is this force along with magnetosphere that protects the earth and its biosphere, from the solar wind by deflecting most of its charged particles (Occhipinti et al., 2014).

1. INTRODUCTION

With the rapid development of Information Communication Technology (ICT), many new services have been introduced in libraries to satisfy the need of users in a better way. Institutional Repository is a type of information service which involves collection, organization, preservation and dissemination of digital scholarly materials such as theses, dissertations, technical reports, journal articles and teaching materials. It is created and maintained by an individual library/ organization or a group of libraries/organizations with an aim to preserve the institutional knowledge .Thus basically it is an online locus for collecting, preserving and disseminating the intellectual output of an academic or research institution in digital form, created and maintained by the institution itself.

“Clifford Lynch defines “ a university based Institutional Repositories as a set of services that a university offers to the members of its community for the management and dissemination of digital materials created by the institution and its community members. It is most essentially an organizational commitment to the stewardship of these digital materials, including long-term preservation where appropriate, as well as organization and access or distribution” ¹

Similarly Mark defines IR as “An institutional repository (IR) is defined to be a web-based database (repository) of scholarly material which is institutionally defined (as opposed to a subject-based repository); cumulative and perpetual (a collection of record); open and interoperable (e.g. using OAI-compliant software); and thus collects, stores and disseminates (is part of the process of scholarly communication). In addition, most would include long-term preservation of digital materials as a key function of IRs”²

INTRODUCTION

Library Consortia is the sharing of resources among the libraries based on a number and utility over their respected areas. The resources that are shared in today’s consortia atmosphere are largely in electronic form such as electronic journals and databases. The aim of consortia is to accomplish what the members of the group cannot achieve individually, and its intention is sharing of resources, manpower and money, etc. It is regarded as a valuable strategy to increase the buying power and risk-sharing capacity of academic libraries over a short term. It is also a chance to maximize the opportunities for joint collection development and resource sharing over the long term. A consortium has the ability to share resources without forfeiting the individuality of member library. As a result, the end-users can collect the benefits of more resources than would be accessible through one library, while staff can adapt the system to meet their individual library’s needs. It can be a single agency with multiple locations around the world, all sharing one name, or the consortia members can retain their own name, but use the name of the consortia to recognize that they are the part of a larger, often worldwide, organization. It acts as director for the electronic resource sharing at the national, regional and local levels. The accessibility of IT-based electronic information products put forth portions of their budgetary allocation for either acquiring or accessing web-based online full-text search services, online databases shared services, on the one hand, permits flourishing consumption and desktop access to electronic resources at highly increasing users demands and growing cost of journals.

Since the industrial revolution in the 1800s, automation got more advanced to efficiently handle sophisticated tasks and increase production. With increasing demands and shortage of labor across the globe, agriculture robots or commonly known as Agribots are starting to gain attention among farmers. Crop production decreased by an estimated 213 crores approx ($3.1 billion) a year due to labor shortages in the USA alone. Recent advancements in sensors and AI technology that lets machines train on their surroundings have made agrobots more notable. We are still in the early stages of an ag-robotics revolution, harnessing the full potential of the Internet of Things in agriculture, with most of the products still in early trial phases and R&D mode.

The present study has been conducted in one of the agro-ecological zones of the state of West Bengal, New alluvial zone. Four villages from Haringhata block in Nadia district were selected from the new alluvial agro- ecological zone to conduct the study. One hundred farmers were selected from the villages of Dalilpur, Mitrapur, Fatehpur, 25 respondents from each. The primary data were collected with the help of structured interview schedule by following the personal interview method. The secondary data were collected from our departmental library, internet, Department of Agriculture, West Bengal, Bidhan Chandra krishi Viswavidyalaya, etc. for establishing the conceptual framework of the study.

Introduction

Recently the terms “governance” and “good governance” are being increasingly used in development literature. Bad governance is being increasingly regarded as one of the root causes of all evil within our societies. Major donors and international financial institutions are increasingly basing their aid and loans on the condition that reforms that ensure “good governance” are undertaken.

Good governance is an essential complement to sound economic policies. Efficient and accountable management by the public sector and a predictable and transparent policy framework are critical to the efficiency of markets and governments, and hence to economic development. Good governance, for the World Bank, is synonymous with sound development management The Bank’s experience has shown that the programs and projects it helps finance may be technically sound, but fail to deliver anticipated results for reasons connected to the quality of government action. Legal reforms, however urgent, may come to naught if the new laws are not enforced consistently or there are severe delays in implementation. Efforts to develop privatized production and encourage market-led growth may not succeed unless investors face dear rules and institutions that reduce uncertainty about future government action.

The Management tools are very useful to achieve the objectives of any extension organization. There are number of management tools, which extensively used for better personal and organizational effectiveness, such as follows: Johari window, SWOT analysis, Agro-Ecosystem analysis, PRA, Transaction Analysis, etc.

• Personal Effectiveness-Johari Window:

The personal effectiveness is very useful for success of management in any extension organization. In Extension organization, the manager or leader has to deal with human beings to obtain the objectives’ of the organization through better personal effectiveness. The basic precondition for personal effectiveness is better self-awareness but understanding one does not alone make a person effective.

The Johari Window: The simple and widely used model of self-awareness is the Johari window, developed by Joseph Luft& Harry Ingham in 1973. In this model, there are two main dimensions for understanding the self: Those aspects of a person’s behavior and style that known to him(Self) and those aspects of his behavior known to those with whom he interacts(Others). A combination of these two dimensions reveals fur areas of knowledge about the self.

The ICAR / Agriculture Universities are playing key role in addressing the gender issues in agriculture as a whole through development of women friendly technologies, efficient extension system and technical backstopping because of the fact that women are the backbone of as nearly contribute 33% of agriculture workforce and silently adorning myriad roles in agriculture sector from home maker to cultivator and even entrepreneur. Traditionally, managing the home, nurturing and grooming children have been considered to be the primary responsibility of women. Besides attending the household chores, they attend to arduous agricultural operations like sowing, transplanting, weeding, harvesting, threshing, agro processing in crop production and cutting and transportation of fodder, milking, cleaning of cattle shed and making of cow dung cakes in livestock rearing. The role of Indian rural women is increasing evidently due to migration of males to urban areas which is having profound and far-reaching effects.

Value Addition in Livestock Product

Mankind has been utilizing different animal species from the dawn of civilization for a variety of purposes viz. production of milk, meat, wool, egg and leather etc. These products are either useful in raw form or in value added form. Value-addition describes economically adding value to the product by changing its place, time and form to characteristics that are more preferred in the market place. Another way of explaining is that what happens when you take a basic product and increase the value of that product, usually the price by adding extras in the manufacturing process, or by tacking on extra products and/or services.

16.1 Introduction

The broad bean is a hardy plant and can withstand sufficiently cold temperatures. It is cultivated on a small scale in India but widely cultivated in Latin America. This is the only bean which is sown in autumn and is grown as a winter crop (in temperate countries). Broad bean is used as green, shelled and dry beans and as a feed for livestock. Plants have distinguishing features like square and erect growing stems which grow up to 30 cm (dwarf cultivars) to 100 cm (tall cultivars).
