Introduction

Agricultural extension has been developing from past more than 100 years. The term was first used by Universities of Cambridge and Oxford, in the year 1867. Chinese people have been following extension approximately from past 2000 years. There are four generations of agricultural extension in Asia: colonial, diverse top-down, unified top-down and diverse bottom-up extension. Communication takes place mainly in two ways in extension system: paternalism versus participation and persuasion versus education, which aims to change behaviour of rural people. Many approaches have emerged in extension which includes ICT based extension.

Education: Education is the production of desirable changes in the behaviour of the people. It is the production of desirable changes in human behaviour in knowledge (things known), attitudes (things felt) and skills (things done), in all of them or in one or more of them.

Behaviour: Includes three components viz., knowledge, attitude and skill

Knowledge (Cognitive): It includes facts, concepts, principles and relationship.

Attitude (Affective): An attitude can be loosely defined as a feeling towards some object, person and situation or idea.

Introduction

In the midst of the rapid speed of global change and in a highly competitive and risky business situation, the knowledgeable consumer gains power, and the market shift towards quick product creation. Innovation has emerged as a crucial component of success, particularly for new businesses, involving the development of economic productivity and operational and working producers (Baron and Tang, 2011). The systematic and planned transformation of a person into an entrepreneur is known as entrepreneurial development. The process of making an entrepreneur involves teaching everyday people how to be business owners, as well as imparting the necessary information, management, technical, financial, and marketing abilities. The definition of the entrepreneurial developmentprograme is a course created to assist a person in enhancing their entrepreneurial drive and obtaining the knowledge and talents required to carry out their position as an entrepreneur successfully (Kumari, 2014).

Our country today is considered independent. We have the freedom to live by our choices, and there is no discrimination between women and men. Nowadays, women and men get equal opportunities to earn their livelihoods. Women’s work is restricted to the households and jobs outside the home to contribute to the family’s economy. As industrialization occurs, the demand for labour and employees is also increasing. This has created opportunities for both women and men to work equally.

Extended Summary

Kiwifruit is recent crop introduction tohorticulture practices in Mid-Himalayan statesin India such as, Himachal Pradesh and J&K in the North-West and Sikkim, Arunachal Pradesh and Nagaland in the North-Eastern Himalayas.Over past few years this fruit has attainedimmense popularity and among consumers due to its nutritional value, while also it has gained appeal among small and marginal farmers owing to its high benefit-cost ratio,particularly through Hi-Tech cultivation techniques.

Kiwifruit,also known as Chinese gooseberry (Actinidia chinensis Patch) is believed to have originated in China,although it gained popularity in New Zealand. In India, Kiwi was first introduced in Lal Bagh at Bengaluru,however,it was soon observed that the fruit could be cultivated well only inthe semi-temperate climate of Himachal Pradesh, around1963.

Women have been seen as necessary as a man. The status of the women and the work progress of the women have been seen as a nation’s overall progress. Without the penetration of women in socio-economic and political activities, the country is considered to stagnate. Still, the devaluation of women commences at birth with the preference for male offspring. This continues through childhood conditioning to the submissive and, later on, the subservient role required of them in the marital home.

Introduction

Quality of Work Life (QWL) is a popular concept among the organizations. Work is an essential part of everyday human life. Work influences the overall quality of life. Human resources are one of the main assets of any organization. Quality of work life (QWL) is one of the important subsystems of human resource management. There are economic, social, psychological and organizational aspects of work life. Many new subsystems are being added to human resource management with employees’ changing needs, culture, expectations, and work environment.

Abstract

This chapter presents the principle of fluidisation and its use in drying of food materials. Being a convective drying process, capacity and kinetics are limited by process conditions and material properties. The influences are discussed as well as presenting the main equations that describe drying in fluidised beds. The main focus lies on hot gas drying, additionally superheated steam drying as well as atmospheric fluidised bed freeze drying and microwave-assisted fluidised bed drying are presented and discussed.

Abstract

Mushrooms are the fruiting bodies of fungi, a group of organism that is different from fruits and vegetables. They are a rich source of good quality protein having more essential amino acids and vitamins with low calories. There are about six commonly known edible mushrooms throughout the world with button mushroom (Agaricus bisporous) being the most familiar and commercially important variety. Mushroom is a highly perishable product with a shelf life limiting to a few days. Soon after harvest, it starts to undergo physiological disorders like shriveling, wilting, liquefaction, browning, textural as well as weight losses and flavour changes. The main responsible factors for the quality deterioration after harvest are respiration rate, browning, bacterial spoilage of mushrooms, temperature and relative humidity. Because of its limited shelf life under ambient conditions of temperature and humidity, the preservation of mushrooms is a matter of concern. Various techniques have been involved in the extension of shelf life of mushrooms including chemical treatments, cooling, modified and controlled atmospheric storage, radiation, drying etc. Drying is one of the most accepted and effective methods for the long term storage of mushrooms. Mushrooms preserved by drying have a pleasant flavour and are used as an important ingredient in several food formulations including salads, instant soups, meats and rice dishes. Various drying processes like sun drying, hot air drying, freeze drying, vacuum drying etc. can be used for the long term storage of mushrooms. As mushrooms are sensitive to temperature, determining the right drying method is the key for the successful and effective operation of the system. The different operating conditions involved in various methods of drying affect product quality considerably. The effect of drying methods on the process and the quality of the dried mushroom is explained in detail in this chapter.

Abstract

Vitamin C is one of the most important phytochemicals and can be found in almost all fruits and vegetables. Since it covers almost all eventualities, being water solute and prone to leaching from cells, thermally labile (one of the most labile vitamins), pH-, metal ion-, light-sensitive, as well as readily oxidizable by ascorbic acid oxidase, vitamin C is selected as the most frequently measured nutrient to evaluate the nutrients loss during thermal processing. It is generally accepted that if vitamin C is well preserved, the other nutrients are also well retained. Higher retention of vitamin C in processed products is highly desired. Herein this chapter reviews the degradation mechanism and kinetics of vitamin C of fruits and vegetables during thermal processing, such as blanching, drying, cooking and frying. It starts with an overview of the functions of vitamin C in human’s health. Then the current status for understanding of the degradation kinetics of vitamin C during thermal processing was outlined, followed by the discussion of its degradation mechanism. At last, potential strategies or alternatives to keep vitamin C are identified and discussed.

Introduction

Thar Desert is unique both from floristic and climatic parameters. Biodiversity in this region survives on a very/ fragile ecosysytem under a highly hostile environment. Major area consists of dry undulating mass of loose sand, thus, leading to shifting sand dunes. The sandy plain is full of sand-hills with serve as low depressions where salt and soda are deposited after drying. The whole area is inhospitable and sterile. Trees are rather a few and far between (Bhandari, 2005).

The Thar Desert of western India is known for its rich and ancient culture system and traditions. The communities have long been part of the Thar Desert ecosystem and have evolved specific strategies to live in harmony with its hostile environment. Orans have remained mainstay in balancing this arid ecosystem. Man of this region has never been greedy as he is today. Orans were repositories of ancient system of gene pool conservation. But, there are unregulated encroachment on the marginal lands and over-exploitation of groundwater resources. Orans has been part and parcel of the lifestyle of the Thar Desert inhabitants. Orans are used to provide vital grazing land for livestock, water, minor forest produce, medicinal plants and green cover for the villages. They were worshipped as devbhumi. Orans preserve the endemic, endangered or threatened species, medicinal plants and wild variety of cultivars found.
