1.1. INTRODUCTION

During the last 30 years, India’s food production nearly doubled from 102 million tons. Almost all of this increase resulted from higher yield in all food grains rather than increase in area, particularly wheat, rice, maize and some extent in pulses and oil seed crops. This has contributed to a significant reduction in poverty from 55% to 26% (Dar, 2011). The increase in yield is the result of scientific innovations in India and other parts of the world and their adoption in India.

In 1871, the Government of India created Department of Agriculture. The impact of these departments in enhancement of crop productivity was not remarkable. Later, the Government of India established the Imperial Agricultural Research Institute in 1905 in Pusa, Bihar to enhance the agricultural research and education. Later, the headquarter of Imperial Agricultural Research Institute has been shifted to New Delhi in the year 1936. The name of the institute has been changed in 1946 as Indian Agricultural Research Institute. To boost the agricultural Research activities, Imperial Council of Agricultural Research was established in the year 1929, subsequently, the name of Imperial Council of Agricultural Research has been changed to its present form of Indian Council of Agricultural Research (ICAR) in 1946. Since then, ICAR playing significant role in all sphere of agricultural research, education and extension. A number of varieties and hybrids of different crops have been developed and released by the scientists of ICAR. To test the outcome of the agricultural research, ICAR has started All India Coordinated Crop Improvement Projects, which provide an efficient channel for multilocation testing of newly evolved strains.

ABSTRACT

North-Western Himalayas have a large area which are degraded and bouldry. Such areas are not fit for crop production. These areas are generally kept unutilized and hence are invaded by uneconomic and invasive species. These lands can be brought under production though establishment of silvipastoral system which has a potential of fodder, fuel and timber production besides conserving natural resources. The paper discusses the techniques of establishment, management and production potential of silvipasture systems in north-western Himalayas.

Cucumber, both slicing and pickling types, is one of the most popular vegetable crops of the family Cucurbitaceae. Like other cucurbitaceous crops, the cucumber also requires a warm season for commercial cultivation and has little or no tolerance to frost. Temperatures above 20°C are optimal for cucumber growth and development. Currently, its cultivars are generally classified as either pickling or slicing types, each with its own set of quality attributes. Pickling types typically have more prominent warts (tubercles) and lighter-coloured skin. They are harvested more frequently at the immature stage, when their length and diameter (LD) ratios are lower. The LD ratio for pickles typically falls within the range of 2.8 to 3.2. On the other hand, slicing cucumbers are harvested and commonly sold in lengths ranging from 12 to 25 cm, with diameters ranging from 1.5 to nearly 7.5 cm. Most slicing cucumbers have cylindrical-shaped fruit with blocky or slightly rounded ends that taper slightly from the stem to the blossom end. Generally, slicers have an LD ratio greater than 4.0, a smooth surface, and thicker skin compared to pickling types. This difference is accentuated because slicers are harvested at later stages of maturity than pickling cucumbers.

Imagine the air around us. Even though we can’t see it, air has weight. Atmospheric pressure is essentially the force exerted by the weight of the air molecules above a particular point on the Earth’s surface.
Think of it like this: Imagine you’re at the bottom of a swimming pool. The water above presses you down, and you feel that pressure. Similarly, the atmosphere, a giant ocean of air, has layers of air molecules, and their weight presses down on everything below, including us.
• Atmospheric pressure is defined as the force per unit area exerted by the weight of the air column extending from the surface of the earth ,to the top of the atmosphere above that area
• It can be explain in simple terms like:
• Air has weight: Just like water or a pile of books, the air surrounding the Earth has mass, and thus, weight due to gravity.
• Weight creates pressure: This weight of the air presses down on the surface. The more air there is above a certain point, the greater the pressure.
• Like a stack: Imagine a stack of blankets. The blanket at the bottom has to support the weight of all the blankets above it, so it experiences more pressure. Similarly, the air at lower altitudes has the weight of all the air above pressing down on it.

Introduction

India is the largest consumer and second largest producer of sugar in the world next to Brazil. Among the sugar yielding crops like sugarcane, sugar beet, palms and sorghum, sugarcane is the second most important agro-industrial crop of the country. It is the only raw material for nearly 538 sugar mills (2014-15), producing about 28 million mt of sugar annually from a sugarcane production of 366 million tons in an area of 5.307 mh. Apart from this, it is the predominant source of potable alcohol, industrial alcohol and fuel-ethanol. In India, 35 million farmers are engaged in sugarcane cultivation and another 50 million depend on employment generated by these 538 sugar factories and other related industries using sugar. Sugarcane occupies a very prominent position in the agricultural crops of India covering large areas in UP, Punjab, Haryana and Bihar (sub tropical) and Maharashtra, Karnataka, Gujarat and Tamil Nadu (tropical). On an average, white sugar production accounts for 74% of total cane produced, 14-15% is utilized for jaggery and khandsari production and the rest is utilized for other purposes including seed.

Jaggery and khandsari, the traditional Indian sweeteners are the natural mixture of sugar and molasses. If pure clarified sugarcane juice is boiled, what is left as solid is jaggery, which contains 65-85% sucrose. Khandsari sugar is a finely granulated and crystallized which contains 94 to 98% sucrose. In the early 1930’s, nearly 2/3rd of sugarcane production was utilized to manufacture these two alternate sweeteners. With the introduction of sugar mills and their multiple growth and better standard of living and higher per capita income, the demand for sweetener has shifted to white sugar which contains purely sucrose (99.7%).

Abstract

Satellite photographs depict exciting evidence on the migratory melodrama of river systems. A study has been conduced in parts of Tamil Nadu using IRS-IA Satellite pictures, archaeology and Tamil literature, which reveals that from Pleistocene to 2700 years B.P.(Before Present) the river Cauvery flowed in a northeasterly direction from the Stanley reservoir via Chinnar, Palakkodu, Mattur, Tiruppathur (Tiruppattur), Gudiyatham (Gudiyattam), Vellore and Walajapet to meet the sea at Madras. From 2700 to 2300 years B.P., it flowed via Uttangarai and Tirukkovilur to meet the bay of Bengal near Pondicherry, over which the present-day Ponnaiyar is a misfit stream . From 2300 to 1300 year B.P. it has flowed via Erode, Tirukkampuliyur, Alagarai , Tiruchy, Kiranur and Pudukkottai meeting the sea in the region where the present-day Agniar and Ambuliar meet the sea. Subsequently, between 1600 and 1300 years B.P., the Cauvery flowed along the present-day tracts of the Vennar and Vettar, after which it seems to have flowed as the Kodamurutti, Arasalar and PalanCauvery from 1300 to 1000 years B.P. From about 900 years B.P. it flowed via Tirupurampayam (Tirupurambiyam), Achalpuram till around 750 years B.P. and then it is stabilised as the Colleroon (Kollidam). Such periods and phases of river migration as well as their implications in the search for archaeological remains are discussed in this paper.

Introduction

The digital farming solutions by various advanced tools and technologies became a prime important to see the future smart agriculture in India with enhanced productivity and farmer’s lifestyle upliftment. The agriculture industry facing challenges from farm to market by climate interfacing and energy conservations practices during farming operations. The use of innovative industry 5.0 is targeting a farming society to achieve high productivity by hardware devices like Robots, Drones, Automated Guided Vehicles (AGVs) working on the basis of Artificial Intelligence (AI), Machine Learning (ML), Deep Learning (DL), Big-Data, IoT and Cloud-based software tools and interactive software programs.

The use of tractors, combine harvesters, power tillers etc. like advanced machineries are practiced in present farming practices by youth farmers; however the digital tools with an automation of existing advanced farm machinery became an attraction to see human comfort. The custom operative design and development of digital tools are essentially becomes a need to innovate and exercise in finding best technologies for Indian farming society. The agricultural society spent several years and now also synthesizing an operational description for digital farming. There are several ways of opting solutions by using new digital logistic tools with software and hardware engagements. As we know agricultural production is influenced by climate, weather, soil properties, plant genetic profile, plant peripheral environment, plant protection, plant nourishing, harvesting and post harvesting like operational tasks. All such a challenging task can be handled by advanced digital tools and technologies.

Rabbits are produced for meat, wool and research and as pets or for a hobby. Meat production is the most important commercial aspect of rabbitry. The domestic rabbit is primarily herbivorous and will consume most types of grains, oil seed cakes, brans, greens and hay. Diets provided, whether home grown or commercially prepared, consist almost entirely of ingredients from plant sources. Although, the producers / farmers mostly rely on home grown feeds, a good portion of the rabbit feed presently used is commercial pelleted feed. Since the rabbit can utilize a certain amount of forage, it has a place in food production by making use of some non-competitive feeds.

Introduction

Fish is a source of valuable animal protein and is considered a health food. This has resulted in increased consumer demand. Fish is now more expensive than meat and other animal foods. Being a highly perishable commodity, fish require immediate processing and various options are available for the value addition of fish. Fish processing, particularly seafood processing and marketing have become highly complex and competitive and exporters are trying to process more value added products to increase their profitability. Value can be added to fish and fishery products according to the requirements of different markets. These products range from live fish and shellfish to ready to serve convenience products. In general, value added food products are raw or pre-processed commodities whose value has been increased through the addition of ingredients or processes that make them more attractive to the buyer and/or more readily usable by the consumer.

Agriculture is derived from two Latin words Ager and Cultura. Ager means land or field and Cultura means cultivation. Therefore the meaning of the word agriculture is cultivation of land.

Definitions

Agriculture is defined in the Agriculture Act, 1947, as ‘‘including horticulture, fruit production, seed production, dairy farming and livestock breeding/keeping, the use of land as grazing land, meadow land, osier land, market gardens and nursery grounds, and the use of land for woodlands where that use is ancillary to the use of land for other agricultural purposes”.

Agriculture is defined as ‘purposeful work through which elements in nature are harnessed to produce plants and animals to meet the human needs’. It is a biological production process which depends on the growth and development of selected plants and animals within the local environment.

Agriculture is defined as the art, the science and the business of producing crops and the livestock for economic purposes.

As an art it embraces knowledge of the way to perform the operations of the farm in a skillful manner, but does not necessarily include an understanding of the principles underlying the farm practices. The skill is categorized as;

Physical skill: It involves the ability and capacity to plough the field in an efficient and quick manner, handling of farm implements, animals, sowing of seeds, fertilizer and pesticides application etc., For example: Taking a straight furrow.

Mental skill: It involves the ability of the farmer to take a decision based on his experience, he decides the correct and accurate timing of operation, such as i) time and method of ploughing ii) selection of crop and cropping system to suit soil and climate, iii) adoption of improved farm practices.

The onion, or Allium cepa var. cepa L., 2n=16, is one of the most important vegetables that are grown and eaten globally (Kiani et al., 2023). It is referred to as the 'queen of the kitchen' because of its wide range of culinary applications (Selvaraj, 1976). It can be eaten raw or prepared in a variety of ways, including as pickles, soups, frying, boiling, and baking (Cattivelli et al., 2021). Apart from being consumed raw, onions also provide excellent raw materials for the processing sector. They can be processed into onion pastes, dehydrated powder, flakes, rings, shreds, and onions in vinegar or brine (Gnanasundari et al., 2023). Additionally, it possesses several health promoting factors such as antihyperlipidemic, anti-diabetic, anti-hypertensive, anti-microbial, immune-protective, anti-obesity properties, and rich in several minerals and vitamins (Pareek et al., 2017). Medicinal value of onion has been known since antiquity; the third or fourth century A.D.'s "Charak Samhita" is one of the medical treatises that mentions it (Ray et al., 1980). Allicin, ajoene, allixin thiosulfinates, sulphites, and other significant biochemical components are found in onion, giving them considerable use and nutraceutical value.

Abstract

Scarcity of resources, economic deprivation, gender bias in wages, prevention from decision making and using income generated by farm activities has made life miserable and unjustifiably hard for rural women. The plight of rural women can be improved by dissemination of latest technologies in agriculture, creating small entrepreneurial outlets for agri-based products, networking of support services for women, development of new and adoption of drudgery reducing technologies, improvement in rural infrastructure to improve the life style and to promote entrepreneurial opportunities, better access to resources, organizing women’s co-operative movement, larger role in decision making, mandatory involvement of women in all agencies and organizations involved in rural development, feedback and follow up of women’s programmes and recognizing the success of rural women by government and its highlighting by media.

History is the continuous record of past events

Heritage is the inherited values carried from one generation to other generation

Agricultural heritage refers to the values and traditional practices adopted in ancient India which are more relevant for present day system.

Agricultural Heritage in India

Agriculture in India is not of recent origin, but has a long history dating back to Neolithic age of 7500-6500 B.C. It changed the life style of early man from ‘nomadic hunter of wild berries and roots’ to ‘cultivator of land’. Agriculture is benefited from the wisdom and teachings of great saints. The wisdom gained and practices adopted have been passed down through generations. The traditional farmers have developed the nature friendly farming systems and practices such as mixed farming, mixed cropping, crop rotation etc. The great epics of ancient India convey the depth of knowledge possessed by the older generations of the farmers of India. The modern society has lost sight of the importance of the traditional knowledge which had been subjected to a process of refinement through generations of experience. The ecological considerations shown by the traditional farmers in their farming activities are now-a-days is reflected in the resurgence of organic agriculture.

Introduction

India is bestowed with wide range of climate and physic-geographical conditions and as such is most suitable for growing various kinds of horticultural crops such as fruits, vegetables, flowers, nuts, spices and plantation crops (coconut, cashewnut and cocoa). Its horticulture production has increased significantly over the last two decades and as per the final estimates, by 2013-14, it has increased to about three times (2.87) since 1991-92 and to about twice (1.90) compared to the production in 2001-02. This has placed India among the foremost countries in horticulture production, just next to China. As per National Horticulture Database 2014, during 2013-14, India’s contribution in the world production of fruits & vegetables was 13.6% & 14%, respectively. Total production of fruits during 2013-14 was about 89 million tonnes while that of vegetables was 163 million tonnes.

Trees have been used in cropping systems since the beginning of agriculture. Throughout the world, at one period or another in its history, it has been the practice to cultivate tree species and agricultural crops in intimate combination. In the tropics, human beings underwent a transition from hunting/gathering to the use of domesticated plants and livestock. As a part of the process, they cut down trees, cleared the debris by burning and sowed crops in the ash-enriched soil. It was the ‘slash-and-burn’ agriculture, a primary forerunner of the present-day agroforestry and a practice that might have originated in the Neolithic period, around 7000 BC.

There are innumerable examples of traditional land-use practices involving combined production of trees and agricultural species on the same piece of land in many parts of the world. Trees were an integral part of these farming systems and they were deliberately retained on farmlands to support agriculture. These practices are now known as agroforestry. However, the ultimate objective of these practices was not tree production but food production.

Organic farming necessitates a shift from conventional to non-chemical agricultural methods and practices. For this, it needs creation of facilities for the production of organic inputs, adoption of crop rotation, green manuring and other best management practices for the organic production of crops and livestock. Further, the ‘towards organic approach’ in intensive agricultural areas and ‘scientific organic farming’ in niche areas have to be implemented for development of an organic farm. The synthesized information on how to convert an inorganic farm into an organic farm followed by its sustainable maintenance is the need of the hour. This chapter holistically deals with designing and maintaing the whole ecosystem organic.

1. Introduction

Nowadays, the growers, policymakers and consumers are talking about organic farming (OF) across the globe. For practitioners, it is still a confusion regarding what and how to practice OF. There is a wrong notion that simple addition of organic manures and the use of chemical pesticides for growing different crops is considered as organic farming. In sense real, organic farms are the cultivated fields without addition of chemical fertilizers, pesticides, livestock additives, etc., and only organic and (or) non-chemical methods are practiced, and the concept or practice is known as organic farming. A large number of farms have been converted from conventional into chemical farms during the last more than 50 years by using synthetic chemicals. In view of the increasing demand for organic products and spiraling soil and human health problems, there is need to transform them gradually into organic farms. So that, it can help enhance soil organic carbon status and fertility which in turn can support crop growth and produce healthy foods besides protecting the environment. However, the extent of chemical used might be varying from one farm to another depending on the crops cultivated, nutrient requirement, pest/ disease severity, availability and accessibility to chemical use, socio-economic condition of the farmers, geographical location, etc.

9.1 Planning land use

Modern techniques such as mechanization, better crop varieties, and the scientific use of fertilizers can transform agriculture, but before they can be effective the use of the land has to be right. No techniques will make it possible to grow a good crop if the soil conditions are unsuitable for that crop, and no conservation works can prevent erosion when the basic cause is trying to grow crops on land which is really unsuitable for arable farming (plate 9.1). The object of land use planning is to determine the characteristics of land, its possibilities, and its problems, and try to match these to a form of land use which will be sustainable and economically productive.

9.7.1 Some planning principles

An often quoted definition is that ‘planning is the conscious process of selecting and developing the best course of action to accomplish an objective’. In the case of Land Use Planning the objective is the efficient intensive use of land resources.

It is difficult to imagine any field of human activity where some form of planning is not essential to achieve the objective. Consider going on holiday. Certainly it is possible to come home from work one evening, throw some clothes into a suitcase, go to the railway station or airport and buy a ticket to the first holiday resort which comes to mind. Some fortunate people may indeed enjoy so unplanned a holiday but for most of us it would be disappointing to find oneself in a mountain holiday resort without climbing boots, or on a sunny beach with only winter clothing in the suit case. No, one is more likely to achieve the objective of a happy holiday by a planned approach and this means going through a logical sequence of steps, i.e.

It is the common maintenance of bee colonies by humans in hives made of man-made materials. The majority of these bees are honeybees from the genus Apis, however there are others that make honey, like Melipona. There are also stingless bees kept. A beekeeper raises bees to produce bees for sale to other beekeepers or to collect honey and other goods that hives generate, such as beewax, propolis, flower pollen, and bee pollen, to fertilize crops. An apiary, often known as a bee yard, is a place where bees are kept.
