Abstract

Several methods of composting are in practice in India such as the anaerobic pit composting, Indore method, NADEP method, bio dung method and vermicomposting. Wastes at the domestic, community and industrial level, can be converted to compost as a viable solution in solid waste management, as well as compost production as a viable micro-enterprise functioning as income generation program. Agricultural waste and residues are an excellent resource for composting at rural centres. Beneficial use of this compost in organic farming as well as in soil bioremediation has been well proven.

Women are the backbone of rural economy. They play a significant role in domestic and socio-economic life of the society. National development is not possible without developing this important and substantial segment of any society. To achieve anything, women are obliged to surmount host of obstacles. The difficulty in gaining access to land, credit and agricultural inputs hampers their potential as producers who feed the world. Barriers of tradition and discrimination have limited their access towards technology, training and education. Moreover, the extension approaches and strategies usually followed for transfer of technology to women are not keeping match with their specific needs and problems. The World Food Summit convened by FAO in 1996 drew up a plan of action to address the major impediments to universal food security. It also called for the full and equal participation of both the genders so as to ensure gender equality and empowerment of women.

Introduction

Beginning with the Green revolution organised training of farmers and extension personnel in the country has now come of age. Since, multiple training institutions government and non-govt have come up, playing a pivotal role in transferring the technical knowledge and know how to the farming community. The turning point and a giant leap in farmers’ training came with the establishment of Farm Science Centre or Krishi Vigyan Kendras by ICAR during 1974. Having district as its jurisdiction area, KVKs have played crucial role in transfer of technology through a well qualified and trained work force at its disposal. As an organization, KVK has its own process for managing the trainers/ subject matter specialists in order to keep them motivated and dedicated to the service of poor farming community. Keeping in consideration some of the job related attributes/ factors that contributes towards effectiveness and efficiency of the SMSs, the present study has been conceived with the main objective- ‘To study the job satisfaction of the KVK trainers’.

Introduction

The key to the advancement of women belong to poor background is self-help groups. Members of society with greater social influence are women. The World Bank estimates that women make up 48.0% of the population in India. Women in India are impacted by a number of economic and social variables. They are essential to any economy. Men and women must be viewed as equal participants in development if a nation is to achieve overall success and positive growth. The nation’s economic growth and social advancement depend on the independence of women. Through collective participation for growth, the empowerment of women through SHGs will benefit not just the individual women but also the family and network as a whole.

Self- Help Groups

Self-Help Groups (SHGs) have developed in order to assist underprivileged women in obtaining services and resources like loans. In 1985, the idea of SHG was first introduced in India. Self-help Groups (SHGs) are informal associations of people who come together to find ways to improve their living conditions. SHGs help in improve the lives of the poor and marginalised segments of society. They also foster financial inclusion. The self-help groups play an important role in ruler women life.India’s Self Help Group movement has emerged as the world’s largest network of community-based organizations.Under this programme, banks were allowed to open savings accounts for Self-Help Groups (SHGs). This was started in the early nineties. Empowering women is crucial to the prosperity and development of the country.

Abstract

The arid Kachchh district, located at the western most part of the Gujarat State in India, is known for its large extent of area under wetland habitat, which is represented by numerous seasonal water bodies and coastal habitats. Vast stretch of grasslands also available in the northern border of the district, the Banni (23⁰ 19’ to 23⁰ 52’ N; 68⁰ 56’ to 70⁰ 32’ E), which encompasses an area of 2,617 km². There are many depressions in Banni, locally known as Dhandh (shallow lakes). During monsoon, rainwater gets collected in these depressions and form shallow lakes. About 34 smaller and bigger size Dhandhs are present in the Banni. Banni communities are highly dependent on the Dhandhs for various purposes. Due to the erratic rainfall in arid Kachchh, Maldharis is highly unstable for livestock in search of fodder and water during drought years. During the normal rainfall years, livestock from neighboring talukas of Kachhh and even from other districts depends on this grassland and Dhandhs. During last decade, the Banni grasslands have seen serious environmental changes due to the invasion of an exotic plant Prosopis juliflora and increasing the salinity are the major issues of Dhandh degradation. Thus, the Banni is gradually losing its capacity to sustain human and livestock population.

Main objectives of the present paper is to examine the local perceptions of wetland and grassland change, socio-economic status, and factors that cause degradation of the wetland and vegetation resources in the Banni grassland.

Sterilization is defined as the process by which an article, surface or medium is freed of all living microorganisms either in the vegetative or spore state.

Disinfection means the destruction or removal of all pathogenic organisms, or organisms capable of giving rise to infection. Chemical disinfectants which can be safely applied to skin or mucous membrane and are used to prevent infection by inhibiting the growth of bacteria are called antiseptics.

Five main methods are used for sterilization. 1. Red heat (flaming) 2. Dry heat (hot air) 3. Moist heat 4. Filtration 5. Radiation.

The killing effect of dry heat is due to protein denaturation, oxidative damage and toxic effect of elevated levels of electrolytes. The lethal effect of moist heat is due to the denaturation and coagulation of protein. In the case of spore, steam condenses on it, increasing its water content with ultimate hydrolysis and breakdown of the bacterial protein.

1. Introduction

 Mushrooms have been part of man’s diet for centuries (Rajarathnam and Shashirekha, 2003). Mushrooms grow on wide range of agro-residues, biodegrade and biotransform them into edible fruiting bodies (Rajarathnam and Zakia Bano, 1988a; 1988b; 1990; Zakia Bano and Rajarathnam, 1988; Zakia Bano et al., 1993; Rajarathnam et al., 1998). Their post-harvest life is very ephemeral at room temperature (Rajarathnam et al., 1983) due to delicate flavor (Rajarathnam et al., 1990) and high moisture content, with a range of chemical constituents (Zakia Bano and Rajarathnam, 1986; 1982; 1988; Rajarathnam and Zakia Bano, 1990; Rajarathnam et al., 1983; 1992). Since, they contain large quantities of water and therefore suffer considerable weight loss during transportation and storage, causes serious economic losses, due to reductions in weight and quality (Gray, 1970). When the supply of water, organic substances and minerals are cut off at harvest, the fresh mushroom enters a deterioration or perishable phase. Cap opening and stem elongation are the usual symptoms of senescence constituting visible evidence of deterioration. At room temperature, the shelf-life of mushrooms cannot be for more than 24 h (Rajarathnam et al., 1983). During this period, there are considerable changes in color, texture and taste. In addition, water is continuously being lost as a result of transpiration and respiration. Additional loss occurs from surface cracks and bruises that develop during growth and handling (Salunkhe et al, 1991). Fresh mushrooms are white or light buff, with no dark marks on either the cap or stem. The veil is closed and the gills are not visible. The upper surface of the caps should be strongly convex and stems should be plump rather than elongated. Mushrooms are grown on compost, usually in mushroom houses where the temperature and humidity can be controlled. Eventually after harvest, the mushrooms can never be able to withstand any increase in temperature and decrease in relative humidity. Mushrooms are commercially preferred at the immature stage characterized by closed caps, invisible lamellae, round stipe and light color. Agaricus development is classified into various stages (Table 1). Thus, the concept of physiology of fresh mushrooms being very complicated, bears a great impact on the delicate problem of extending the storage life. The various means and methods studied and adopted by various researchers to aim at extended storage life of fresh produce, underlined by its physical, chemical and biochemical properties and also development of value added products are critically evaluated.

Storage is one of the most important aspects of post harvest handling of fruits and vegetables. The main objective of storage is to extend storage life of fruits and vegetables and increase their period of availability. A substantial quantity of fruits go waste in India due to lack of proper storage facilities. Storage of fruits and vegetables is practiced for various reasons. Proper post harvest handling of fresh horticultural produce helps in extending  period of availability of wide range of  fruits and vegetables round the year, prevention of seasonal market gluts, orderly marketing, better return to grower and  preservation of  nutritional qualities. The   long  term  storage  of  fruits  and  vegetables is expensive and requires high level of technical  knowledge of crop. However, an orderly marketing reduces storage period considerably. 

Storage : It can be defined as keeping the commodity fresh or processed in safe condition with minimum of deteriorative changes for later use.

Reasons of Deterioration During Storage

Abstract

Pulses constitute an important component of the diet and are a major source of protein in vegetarian diet. India has largest area under pulse cultivation and produces a variety of pulses. A large portion of this produce gets spoiled due to insect and fungal attack. A variety of insecticides and fungicides are used for the control of pest during storage. There is an increasing trend towards the reduction in the use of pesticides in storage due to strong demand from consumers to choose food with no pesticide residue, development of insect resistance to pesticides and the impact of pesticides’ use on environment. All these have posed a challenge to refine the existing management procedures of storage and commodity to find the optimal solution. Controlled/ Modified Atmosphere storage offers an alternative to the use of pesticides extends storage life and maintains product quality. The Controlled/Modified Atmosphere is created by altering the composition of the atmosphere in terms of CO2, O2, and N2 concentration. High CO2 produce undesirable conditions for insects and microbes and thus control their activity.

1. INTRODUCTION

To over come the problem of glut of perishables and to regulate the market, storage of such commodities is a 'common' practice. Storage of fruits and vegetables also makes available these commodities in the off-season. Needless to say, storage is a powerful tool in the prevention of postharvest losses and to give remunerative prices to the farmers. The management of temperature and relative humidity are the most important factors determining storage life of horticultural produce. The natural means like ice, cold water, night temperature have been used for long time for protecting food materials from spoilage and these are still common. However, with the development of innovative technologies, it is possible to achieve optimal environments in the insulated stores. All these aspects are discribed in this chapter.

Introduction

India is bestowed with huge production of fruits, vegetables, cereals, millets, sugarcane along with meat production, milk production, fish production and poultry. Despite such a huge production in India, owing to perishable nature of these produce around 25-30 per cent of the produce is being lost as post harvest loss. The one important reason for this may be the production of the crops are season specific and during the peak season the production is more while demand for consumption is less. It may be possible to cut down losses to great extent, if these produces may be transported from the produce states to those who are not producing due to agro-climatic reasons. So for making transportation of the perishable a successful venture in decreasing post harvest loss, there must be proper storage facilities both at producing site as well as marketing place. The aim of the storages must be to keep the produce in saleable condition during entire storage periods. Some products are stored for short period whereas fresh fruits, vegetables require cold storage. Foods before keeping into the storage room need some pre-storage treatments for better results.

Proper marketing of perishable commodities such as fruit and vegetables often requires some storage to balance day-to-day fluctuation between harvest and sale or for long term storage. Storage of horticulture produce is attempeted with a view to extend period of availability. Storage controls shelf life of produce by controlling rate of respiration, transpiration, ripening and biochemical changes all of which are responsible for shelf decomposition/deterioration of produce. Further, different types of storage have different attributes in minimizing microbial infection and thus add to better storability of produce.

Abstract

Crop cultivation is a complex process and involves a set of activities like land preparation, planting, pest control, irrigation, nutrient management, harvesting, marketing, etc. Entire cycle of crop production requires multitude of information by the farmers. Despite many efforts over the years to disseminate and transfer agriculture knowledge to the stakeholders, large amounts of expertise and knowledge are still out of reach to most of them. Agriculture knowledge may be contained in the corporate database, or it may reside undocumented inside the brain of the researchers or even stored in locations unknown to the majority of the people in the organization. Large sections of the farming community, particularly the rural folk, do not have access to the huge knowledge base acquired by agricultural universities, extension-centers and businesses. In this respect the main challenge is to find this knowledge and apply it to the decision making process involved in agriculture development.

Abstract

The control of micronutrient deficiency is a realizable goal, notwithstanding the magnitude of the task, challenges and constraints that need to be resolved. Since wheat products particularly maida and atta form the major raw material in widely consumed food items like chapati, bread and biscuit. Fortification of flour as followed in many other countries could be an important strategy to help realize this goal. The technology of flour fortification is effective and cost affordable. Effective flour fortification program would require collaboration between scientific community, governmental and non-governmental agencies, and industry and consumer groups.

Introduction

The share of Agriculture sector in GDP is declining over the years. This is because, of the a large gap in the latest known technology and technology being used by the farmers. Our human resources are not being utilized properly because our people in the villages are ignorant about many scientific innovations.

In Andhra Pradesh, more than 70.00 per cent of the population is dependent on agriculture but its contribution to the state GDP is only 30.00 per cent. It is felt that this low contribution to the GDP by the Agricultural sector is due to uneconomic returns

Indian agriculture is passing through a phase of reforms, owing to its shifting emphasis towards diversification, intensification, commercialization and sustainability, which has posed newer challenges before the extension functionaries. Understanding and appreciating the information needs of different clients (farmers, farm women, labourers, youth, etc) and providing quality extension service is central to its success, which needs quality manpower at different levels. Among extension services training need resources is a key input for human recourses development and contributes substantially to face the challenges by all concerned. Farmer led extension approach gives farmers the opportunity to share their experience and practices through a method demo with fellow farmers in the area. It was noticed that farmers who are successful in their farming venture have established credibility among their peers. These very same farmers are just waiting to be tapped to act as extensionist.

Abstract

‘Made in India’ is no more a sign of poor quality. However, in the field of food grain exports, India is still lacking the required determination. The Indian food grains get rejected in the International market because of its out-dated post harvest technology (PHT). The Food Corporation of India (FCI) is the nodal national agency for the procurement, storage, processing and transporting of food grains, and their further distribution through the Public Distribution System (PDS). The government fixes the procurement price as well as the distribution price of the food grains, and the FCI has to accept it. The government compensates the resulting loss through subsidy. The government, through FCI, must encourage cultivation and marketing of premium quality food grains, by offering suitable incentives to farmers. The cost of marketing, storage and transporting of food grains can be considerably reduced with simultaneous improvement in quality of the end product, if the prevailing bag handling is replaced by bulk handling, storage, and transportation. However this needs closer coordination between various departments of the Ministry of Food and Ministry of Railways. The President of India revealed his vision to make India a developed country by the year 2020. To achieve this, the current post harvest losses to the tune of 10 percent must be reduced to 2 percent. This is possible if the government takes bold political decision supported by equally firm and time-bound necessary

Introduction

Castor (Ricinnus communis L.) is an important non-edible oilseed crop and occupies an important place in the country’s vegetable oil economy. The crop is mostly confined to Gujarat, Andhra Pradesh and Rajasthan. Although other states like Tamil Nadu, Karnataka, Orissa, Maharashtra, parts of Madhya Pradesh, Bihar and Chhattisgarh cultivate castor, their contribution to either area or production is limited. Presently, castor is grown over an area of 8.7 lakh hectares with a production of 11.7 lakh tonnes and productivity of 1352 kg/ha in the country (2008-09). Castor oil finds application in manufacture of a wide range of ever expanding industrial products such as nylon fibres, jet-engine lubricants, hydraulic fluids, soaps, varnishes, paints, medicines and a host of similar other products. Castor cake is used as manure and also as nematicide. Gujarat and Andhra Pradesh put together contribute to 68.5% of the total castor area and 80% of the total castor production in the country. The crop has been cultivated under resource-rich irrigated conditions in Gujarat with very high productivity (1963 kg/ha), while in Andhra Pradesh, the crop has been cultivated under rainfed and poor resource management conditions, with very low productivity (509kg/ha).

Introduction

Cassava is an important tuber crop in India grown in 2.7 lakh hectare area with a production of 71 lakh tonnes. The average yield of tapioca is 22 tonnes per hectare. Cassava is a richest source of starch (25 to 35%) mainly processed for starch and sago. Cassava is an industrial crop of Tamil Nadu occupies 32.97% of the area and 45.98% of the production in India. (Edison et al 2006). In Tamil Nadu major traditional tapioca growing districts are Salem, Namakkal, Erode, Cuddalore, Dharmapuri and Kaniyakumari mostly as rainfed. Among the districts Salem District stands first in area (27000 ha) and with the production of 10.475 lakh MT(Anonymous, 2006).
