Introduction
Spices have been considered significant in the culinary art from time immemorial. India, “The Homeland of Spices” is one among the largest producers, consumers and exporters of spices as well as spice products. Spices comprise different plant components such as floral parts or fruits or berries or seeds or rhizomes or roots or leaves or kernel or aril or bark or bulbs. The recorded history of the use of spices dates back to 5000 years or so from the Egyptian or at the most from the Indus valley civilization. Spices are used for flavouring, seasoning and imparting aroma in various cuisines. Besides these inherent qualities, some of them are known to be fungistatic, antimicrobial or antibiotic. They are also processed into numerous ‘value added’ products such as oleoresins, essential oils, curry powder etc. Black pepper, cardamom and turmeric are the major spice crops and its production and marketing are the main economy stays of lakhs of people of the country. Billions of rupees are involved in domestic trading and foreign export. Therefore, it is highly imperative for farmers to adopt the advanced practices to sustain spices productivity. Even, additional income could be generated from the intercropping of spices from the interspaces in mango orchards (Shukla and Adak, 2020). Thus the present chapter included all aspects of production to protection and value addition for  the benefits of growers.

Vegetative propagation enables horticulturists to multiply plants while retaining desirable genetic characteristics of selected mother plants. This chapter covers important methods including cuttings, layering, budding, grafting, division, and specialized vegetative structures. The physiological basis of rooting, wound healing, callus formation, compatibility, and environmental requirements is discussed. Grafting and budding are particularly important for combining desirable scion characteristics with suitable rootstock traits such as vigor, disease resistance, stress tolerance, and adaptation. Proper sanitation and selection of healthy propagation material are emphasized to minimize pathogen transmission. Modern techniques such as rooting hormones, mist chambers, protected propagation, and clonal multiplication further improve the efficiency and uniformity of vegetative propagation.

Introduction
 
The future of functional foods is bright and there are several reasons for the growing interest in “functional” foods, such as awareness of personal health deterioration, led by busy lifestyles with poor choices of convenience foods and insufficient exercise; increased incidence of self-medication; increased level of information from health authorities and media on nutrition and the link between diet and health; scientific developments in nutrition research; and a crowded and competitive food market, characterized by pressurized margins. Now, the consumer is well aware of the relationship between diet and health. Consumers understand that the risk for chronic diseases such as heart disease, stroke, colon cancer, and type II diabetes is possibly preventable by modification in their diet pattern. This scientific progress in understanding the relationship of diet to disease, along with increasing health care costs and the consumer’s desire to initiate healthy eating and lifestyle habits, makes this a potentially fertile ground for the development of food products that meet these demands.

Lentil (Lens culinaris, 2 n = 2 x = 14, family Fabaceae/Leguminosae, subfamily Papilionaceae, essentially self-pollinated annual) has average global area, production and yield during 2015-17 as 5.56 million ha, 6.55 million tons of production and 1178 kg/ha as per FAOSTAT. The top ten lentil producing countries globally are Canada, India, Turkey, USA, Nepal, Australia, Ethiopia, Bangladesh, China, and Kazakhstan. India produced 0.94 million tons of lentil from 1.60 million ha with a productivity of 587 kg/ha during 2010-11. The corresponding figures for the year 2018-19 are 1.56 million tons, 1.51 million ha and 1033 kg/ha indicating a significant gain in the productivity over the years (Directorate of Economics and Statistics, 2020). The top states in lentil production in India are Madhya Pradesh (40%), UP (30%), West Bengal (11%) and Bihar (9%). Rest of the states is insignificant. The plant was given the scientific name Lens culinaris in 1787 by Medikus, a German botanist and physician.

Development of fungicide resistance in a fungal disease pathogen is a major concern for some of the important diseases in their management. This can be overcome by designing of fungicide use strategies to manage the threat of fungicide resistance.

Methods and procedures for the qualitative characterization and quantitative analysis of different constituents of soil organic matter are presented in this Chapter.

20.1. Moisture

The soil sample should be in an air-dry condition after mixing, sieving and grinding. When stored in a moisture-tight container, the free H₂O content should not vary appreciably during storage. While most determinations can be done on air-dry samples, for certain purposes such as obtaining summation values, a moisture content value is required.

Introduction

The problem of dealing with climate change, a critical global issue, has come to define our era. Human activities are rapidly altering Earth’s climate, with far- reaching repercussions for many industries, including agriculture. The necessity for environmentally responsible food production is pressing as the global population rises. One possible way to lessen the effects of global warming on food production is to adopt the sustainable agriculture practice of striking a balance between environmental protection, social justice, and economic viability. The impacts of climate change on farming may be seen all across the world right now. Global food security is threatened by climate change, which is causing higher temperatures, changing precipitation patterns, and increasing extreme weather events. Greenhouse gas emissions, deforestation, and unsustainable farming practices all have a hand in accelerating global warming. Therefore, it is crucial to tackle the double problem of lowering agriculture’s environmental imprint while also adapting it to climate change. Sustainable agriculture works toward a compromise by encouraging robust and flexible agricultural practices. It aims to ensure the sustainability of food production in the future while reducing environmental effects by incorporating climate change adaptation and mitigation techniques into agricultural practices. Agricultural systems can be made more resistant to climate change by the use of sustainable farming practices such as agroforestry, crop diversification, soil conservation, and water management. Sustainable farming practices help communities adapt to climate change, boost local economies, and secure food supplies for future generations.

A well-managed nursery is essential for producing healthy, uniform, vigorous, and field-ready planting material. This chapter explains nursery planning, site selection, propagation structures, growing media, containers, trays, irrigation, fertilization, sanitation, pest management, hardening, and transplant quality assessment. Protected raising techniques using shade nets, polyhouses, insect-proof structures, and controlled environments are discussed for improving germination and seedling survival. Particular attention is given to biosecurity, disease prevention, substrate sterilization, water quality, and environmental control. The chapter also introduces quality indicators such as root development, shoot growth, and physiological fitness. Efficient nursery management reduces establishment losses and provides the foundation for productive and profitable horticultural enterprises.

See also B horizon, C horizon.

Abatement: Refers to reducing the degree or intensity of greenhouse-gas emissions.

1. Introduction

There are a large number of indigenous rice varieties in India, which are still grown by the tribal people and small farmers of the remote areas where the modern agricultural practices, sufficient foods as well as healthcare systems are a dream. Nature has provided them some alternative ways. They have different indigenous rice varieties with its nutritional and medicinal values. Until recently, rice was considered only a starchy food and a source of carbohydrates and some amount of protein. Rice protein, though small in amount, is of high nutritional value (Chaudhary and Tran, 2001). It has extensive curative properties known from the ancient days. In fact, specific rice varieties with medicinal properties were cultivated and used in the treatment of some ailments in different counties of South East Asia.

During recent times, both at national level and international levels, the land races are being preserved in the gene banks. The scientists said that they were also checking these land races for some such characteristics which were not available in the existing varieties so as to incorporate the same in the present varieties (Sultan and Subba Rao, 2013). Traditional varieties are experiencing an increasing trend among consumers, due to their incredible health benefits for example the traditional varieties possess higher amount of glutamic acid, fiber and vitamins. Some people also credit traditional varieties with other health benefits, such as giving sensations of cooling in the body, improves vocal clarity, eyesight, fertility and mitigating rashes (Caius, 1999).

Crop residues are valuable natural resources that may be managed to maximize various input use efficiencies. These are a great source of organic materials for improving the soil structure, water holding capacity, the soil's ability to withstand pH variations, increasing the cation exchange capacity, reducing the phosphate fixation, as a storehouse for micronutrients and secondary nutrients especially in organic farming. Organic matter serves as a source of energy for soil fauna and microbes, which are the main agents controlling the decomposition and release of mineral nutrients in organic soil ecosystems. Crop leftovers are frequently burned by farmers, especially after harvest, which depletes the soil's nutrient content and microbial population and produces greenhouse gases. Each year, a sizable amount of crop residue is produced and if used efficiently, they may provide partial or full amount of the nutrient budget required under organic farming for the production of annual or perennial crops besides achieving resource conservation and environmental sustainability.

1. Introduction

Crop residues are the non-economic plant parts like straws, stubble, stover etc., that remain in the field after harvesting the economic product. Crop remains from threshing sheds such as groundnut shells, oil cakes, rice husks, corn and sorghum cobs or discarded during crop processing can also be utilized in organic farming. India produces 108.75 MT of wheat, 121.46 MT of rice seed, 30.24 MT of maize seeds, 49.66 MT of millets seeds (jowar, bajra, ragi, and small seed millets), 392.8 MT of sugarcane, 46.11 million bales of fibre crops (jute, mesta, cotton), 25.58 MT of pulses and 36.57 MT of oilseed (Agricultural statistics at a glance, 2021).

Abstract

Various studies put the percent of rural women engaged in agriculture and related activities in India around 65-70%. A majority of them are from economically and socially deprived category and qualify as “poor” or below poverty line. In rural India women play the role of agricultural labourer, fuel gatherer, food provider and home maker. Both central and state governments have framed and implemented various programmes to improve the living conditions of rural people. Measures have also been taken to provide employment and alleviate poverty. Generally these programmes fall into the category of wage employment, self-employment, housing and habitat development, and watershed development programmes. The last mentioned focuses on various water supply schemes to the rural poor and socially deprived. These programmes are evaluated in this paper. Although they are intended to benefit all the poor and jobless in rural Karnataka, the benefits reach women too because of their role as homemakers and food providers. Be it wage earned or drinking water or shelter, these programmes, if implemented sincerely, make the life of farm women less laborious and more comfortable.

While reviewing the status of education and research on medicinal plants in Bangladesh, it was found that there are 27 government and private educational institutions currently engaged in offering Bachelor or Diploma degree on Unani and Ayurvedic systems and training of traditional medicine practitioners in Bangladesh. Several other public and private universities have included different aspects of medicinal plants in their syllabus with other degrees at undergraduate and post graduate level. At present, there are 277 Unani, 201 Ayurvedic and 32 herbal drug manufacturers in Bangladesh with 6498 Unani, 4058 Ayurvedic and 537 herbal products registered by the Directorate General of Drug Administration. About 500 species of plants are identified which possess medicinal properties and are distributed throughout the country. There is no distinctive research organizations at present for conducting planned research solely on medicinal plants; though, the Bangladesh Forest Research Institute have some research programme on medicinal plants. Hamdard University- a private university is offering degree on Unani and Ayurvedic systems and conducting some research including drug manufacturing. Bangladesh Agricultural Research Institute with other public and private universities are conducting some hectic research on medicinal plants including some high yielding variety development. The Government of Bangladesh (GoB) have taken some initiatives for development of Unani and Ayurvedic medicine sector like making ‘Bangladesh Unani and Ayurvedic Practitioners Ordinance, 1983’, ‘National Drug Policy 2016’, establishment of ‘Board of Unani and Ayurvedic Systems of Medicines (BUASM)’, etc. But proper implementation of the ordnance, strengthening the activities of BUASM and taking organized research programme on medicinal plants are very much essential for having skilled professionals, quality drugs and research.

Digestive System and Digestion in Chicken

Studies on structure and functions of digestive system of chicken play important role for their nutrition and feeding. Functions of each part are given below (Fig 35):

Mouth: Birds feed through the beak. The horny upper and lower mandibles form the beak. Lips, teeth, cheek and soft palate are absent. The dagger-like tongue helps to force the feed into the esophagus. Chicken has 24 taste buds with high sense of taste. Absence of teeth makes the particle size of the feed important.

Esophagus (Gullet): It is made of loose fibrous tissue and serves as a tube to pass the food from mouth to crop. This is relatively long because of the long neck of the fowl.

Crop: (Ingluvius): It is a pouch like structure of esophagus to store, moisten and soften the food. It gives information about the feeding habits of the fowl.

Proventriculus (Glandular stomach or True stomach): It is an enlarged glandular ovoid structure of the esophagus connected to gizzard. It secretes pepsin and Hydrochloric acid.

Gizzard (Muscular stomach): Disc shaped muscular organ with two pairs of strong thick muscles and lined internally with a thick horny epithelial covering called the Koilin layer. Coarse materials are ground well by its powerful contractions with the support of the grit that birds consume.

12.1 What is Climate Change?
 
The earth receives short-wave radiation from the sun, one-third of which is absorbed by the atmosphere, ocean, ice-land and living organisms. The energy absorbed from solar radiation is balanced, in the long-term, by the outgoing radiation from the earth and atmosphere. While short-wave radiation from the sun can easily pass through the atmosphere, the long-wave radiation emitted by the warm surface of the earth is partially absorbed by trace gases in the atmosphere called greenhouse gases’ (GHGs).

1. Introduction

Processed foods have become a way of life in the modern world. Manipulation of chemical and physical properties facilitated by modern food technology and followed by addition of food additives has created a plethora of innovative food products that offer consumers greater convenience, variety, safety, satiety and quality.
Food additives have been in use for centuries for preservation, for providing improved appearance or desired texture and flavour. Preservation of foods started with salting and smoking. The Egyptians used colours and flavours, Romans used saltpeter and in India, turmeric is being used. Similarly additives such as baking powder as a raising agent, thickeners for sauces and gravies and colours- synthetic as well as from natural sources are being used.
Today more than 2500 food additives have been in use mainly due to the spurt in the research activities in food science and technology that are aimed at providing different characteristic functions to foods. Out of these, about 1300 are the flavouring additives.

We are entering an era when certain environmental conditions will exert a degree of concern which has never been before encountered by man in the course of human history.

The survival of human beings depends on the realisation that they have to live in harmony with the various elements of the environment which are interconnected.
    
(i)     An understanding of the components and processes which takes place in the environment.
    
(ii)     The relationship between different abiotic and biotic components and the assessment of resources with reference to needs of people in a region is essential for their survival.
    
(iii)     A reduction in rate of growth of population in developing countries and a reduction in consumption of resources by developed countries would lead to a balance between population and resources. In this manner, the awareness of the problems faced by environment would enable people to take appropriate decisions. This makes the earth habitable for future generations.

Agroforestry is a land use system that involves two or more plant species at least one of which must be a woody perennial. When perennial woody and herbaceous components are grown together on the same piece of land their performance would largely depend on their ability to share various growth resources in a given environmental situation. Due to difference in growth pattern and resource requirement of the components in agroforestry situation, a close interactive relation is obvious. Thus, careful management practices for the components are required to establish a successful agroforestry system. The characteristics of the trees and crops, and their interactions, can be modified with good management practices in order to take advantage of the positive characteristics and minimize the effects of the negative ones. Effective and efficient agroforestry management may be divided into two groups; tree management and agricultural crop management.

FACTORS AFFECTING THE SELECTION OF TREE SPECIES

Trees in an agroforestry system contribute significantly to the total output of the system and therefore, success of the system depends on the selection of the tree species. The following factors are to be considered to choose the best tree species for the agroforestry systems in a particular site.
