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.

Plants yielding oilseeds are economically important in India next only to food crops and play an important role for sustainability of  cropping systems and soil health. Oilseeds scenario in the country underwent a sea change in  last fifteen years. India changed from net importer in  1980s to a net exporter  during  early 1990s. Again, it is back to net importer importing more than 40 % of its annual edible oil needs. Country’s demand for edible oils is  rising to double  the current level of 4% (as against productivity growth of 2% in 1986-2001) in  next 12 years (Hegde 2004). To meet  challenges of oilseeds production, there is  need to adopt multi-pronged strategy which involves enhancing production through area expansion and productivity improvement through improved technologies and value addition . As a progressive step in this direction of self sufficiency, there is  need to identify alternative oilseed trees/plants which can be grown in wastelands. There are more than 300 different kinds of tree species which bear seeds  rich in oil and  introduction of simarouba is an important step in this direction. National Oilseeds and Vegetable Oil Development (NOVOD) Board under Ministry of Agriculture  identified simarouba as a potential Tree Bearing Oilseed (TBO) for popularization in India and placed it in  first place in their list of importance.

1. Introduction

Bamboo has historically been an integral part of human culture. Bamboo is a mystical plant representing symbol of strength, flexibility, tenacity, endurance and compromise. Throughout Asia, bamboo has for centuries been integral to religions, ceremonies, art, music and daily life. Bamboo provides numerous environmental benefits such as playing a critical role in the balance of oxygen/carbon dioxide in the atmosphere. Bamboo is the fastest growing canopy for the regreening of degraded areas and generates more oxygen than equivalent ultraviolet rays. It is an atmospheric and soil purifier. Its soil conservation properties create an effective watershed, stitching the soil together along fragile river banks, deforested areas, and in places prone to earthquakes and land slides. Its fast growing and high yield nature makes it a highly valued renewable resource. Its low cost and abundance call for its utilization to a full extent. 

A Overview

Genetics is a branch of biology concerned with heredity and variation.

Genes are the unit of inheritance and are composed of DNA.

The effects of genes are noticeable at the molecular, cellular, family, and population levels.

Genes are DNA sequences that instruct cells to produce particular proteins, which in turn determine traits.

Genes can exist in more than one form and the variants of a gene arise by mutation.

An allele is a variant of a gene that alters its expression in a detectable way. Alleles can be dominant or recessive.

A polymorphism is a particular sequence of DNA that varies in one percent or more of the population.

Single nucleotide polymorphisms are single base pair sites that differ among individuals.

Chromosomes consist of genes and associated proteins.

The human genome consists of 22 pairs of autosomes and one pair of sex chromosomes.

A karyotype is the photographic catalog of the human chromosomes.

Specialized cells and tissues arise by differentiation from the stem cells of the early embryo.

Pedigree diagrams enable recessive and dominant traits to be followed through multiple generations of a family.

A gene pool is the collection of alleles in a population.

Comparative genomics is leading to a more detailed and subtle understanding of evolutionary relationships among species

Gerbera, commonly known as Transvaal Daisy, Barberton Daisy or African Daisy, is cultivated throughout the world under a wide range of climatic conditions for its attractive flowers. It is highly suitable for beds, borders, pots and rock gardens. The wide range of colour and the attractive shape of flowers suit very well in flower arrangements. The cut blooms have long vase life. Today Gerbera is known as an important commercial flower crop and belongs to the most important plant species in the world, together with the rose, chrysanthemum, carnation and tulip. Gerbera is amongst the ten most important commercially grown flower crops in the world.

Quantitative genetics is often considered to be the bedrock of crop breeding research. Understanding and analyzing complex nature of genetic data based on its quantitative traits is of much importance in any perennial crop improvement research. Genetics and statistics are the two sides of a same coin to unravel complex problems in the study of inheritance and heredity of quantitative traits. Application of statistical methods in genetics probably dates back to 1880’s when Galton (1886), in his historic study about inheritance of mid-parent’s heights on their children, adopted the theory of regression. In the early 1990’s, Fisher (1918), in his study on correlation in Mendelian inheritance, utilized the analysis of variance (ANOVA) technique. The distribution of quantitative traits in a population follows the normal distribution (also known as Gaussian distribution or bell curve), the central concept of statistical theory. Number of research experiments after these two historic studies essentially concentrated on analyzing vast genetic data of several quantitative traits and attributing the source of variability in traits to genetic variation. Furthermore, as emphasized by Narain, (2010) the classical genetic basis of continuous variation based on the infinitesimal model of Fisher and mostly using statistical methods has since undergone major modifications. Largely due to rapid advances in computational tools for data analysis, complex techniques, which better explain the reality in the vast data generated by the researchers, are being employed. Accordingly, an attempt is made not necessarily be exhaustive, to discuss about traditional data analysis techniques leading to modern aspects with special reference to perennial fruit crops.

Introduction

Over the years, processed food industry has become the largest growing industry in the world. The convenience food industry with the state of the art technology has been proved very successful in reaching every household and have started replacing fresh and healthy foods with the processed ones (Srinivasan and Shende, 2016).

Demand for processed and convenience foods are constantly on rise and convenience food segment is rising by leaps and bounds. Changing life style, food habits, displacement of rural population to urban centres, insufficient time to prepare healthy food and changing socio economic needs have led to the industrialization of the food supply and resulted in the development of convenience foods and today a great variety of the same are available for sale to the consumer throughout the world (Tillotson, 2003).

These convenience foods are available readily, convenient, inexpensive with pleasing organoleptic quality, requires minimal or no preparation before consumption. Varieties of convenience foods which are available in the market play a prominent role in the food choice of today’s consumer, and they include frozen and canned vegetables, bakery products, soups, sauces, prepared meat and fish, chilled and frozen dairy products as well as ready to eat and shelf stable products (Tillotson, 2003).

Rapid switchover of the consumer from the traditional dining practices to fast food centres, generally feed on quick and easily made products called fast foods, often termed as unhealthy junk foods. These foods are rich in saturated fatty acids, several refined components, high carbohydrates etc., which ultimately lead to the negative impact on physical and mental health of the consumer, contributing to several chronic diseases such as cardiovascular complications, cancer, atherosclerosis, liver disease, type 11 diabetes (Veggie et al., 2018) etc.

Therefore, focussing much about the health of the consumer, there is a great need for a healthy and a balanced diet to meet the basic needs of the human body (Mendes et al 2013) with an appealing organoleptic properties and appearance.

12.1 The nature of gully erosion

Gully erosion is spectacular and widespread, and so it is often used by conservationists as a characteristic symptom of erosion. As a result there is a danger of its importance being over-emphasized. Certainly it is most important as a source of sediment in streams, but in terms of damage to agricultural land or reduction of agricultural production, it is usually not very important for the simple reason that most land subject to severe gully erosion is of little agricultural significance. The really spectacular erosion so popular in non-technical reports shows large areas cut up by deep interconnecting gullies, but this situation is usually found in semi-arid climates unsuitable for any serious agriculture, or on soils which have such adverse chemical or physical properties that their potential production is very low. Added to this is the fact that gully control is always difficult and expensive, so the cost of reclamation usually exceeds the value of the land. Certainly in the sense of reducing the amount of eroded soil choking the dams and rivers it may be highly desirable to do something about gully erosion, but it is very much a case of prevention being better than cure. Limited resources in manpower, money and materials can usually be better employed in preventing future gullies than in curing existing ones.

The worldwide occurrence and recognition is well demonstrated in the variety of names: in English and American - gully, in Egypt - wadi, in South Africa - donga, in French-speaking lands - ravine, in India - nulla, in South America - carcava, or arroyo, and many others. The definition is the same in any case, a steep-sided eroding watercourse which is subject to intermittent flash floods. They are more common in semi-arid climates with infertile soils and sparse vegetation, but some spectacular examples are found in tropical forests in deep soils with dense vegetation.
