Abstract

Re-constituted rice-premixes made by extrusion, has been successfully formulated for the fortification of market rice with vitamin A (retinyl palmitate and betacarotene) and iron. The statistics of vitamin A deficiency (VAD) and Iron deficiency anaemia (IDA) are alarming in the developing world, particularly in India. In fact, India is second largest producer as well as consumer of rice in the world, so fortification of rice with vitamin A and iron seems to be a successful solution to reduce the VAD and IDA in India. In order to design the final formulation, eight formulations containing target micronutrient profile were tested for vitamin A (both retinyl palmitate and beta-carotene) and iron retention for a period of six months under ambient (24-26 ⁰C) and elevated temperature (40 ⁰C) conditions. Nonsignificant iron loss was observed during six months of storage time under both ambient and elevated conditions. The higher retention of retinyl palmitate and beta-carotene was observed in formulation 5 and 8 respectively. In F5, the retention of retinyl palmitate was 73% and 66% and in F8, retention of beta carotene was 70% and 63% under ambient and elevated temperature conditions respectively after six months of storage. Substituting the original, vegetable shortening with palm shortening resulted in increased retention of retinyl palmitate and beta carotene in formulation 5 and 8. Thus, increased antioxidant effect of natural antioxidants in palm shortenings contributed to stability of micronutrients.

Definition

Based on various standard sources, plant breeding has been defined in various ways. A few important and standard definitions are:

The art and science of changing plants genetically.

Plant breeding is the genetic adjustment of plants to the service of man.

Improvement of crop plants as the result of process of evolution directed by man for his own ends. The basic principles of plant breeding are thus the principles of evolution. Directed evolution as imposed in plant breeding differs from natural evolution chiefly in a greatly reduced time-scale, and in a more precise control over the factors which govern hybridization and selection.

The science and art of manipulating the heredity of plants for a specific purpose.

Plant breeding is a deliberate effort by human to nudge nature, with respect to the heredity of plants, to an advantage. The changes made in plants are permanent and heritable and the professionals who carry out this task are called plant breeders. This effort at adjusting the status quo is instigated by a desire of humans to improve certain aspects of plants to perform new roles or enhance existing ones. As a result, the term “plant breeding” is often used synonymously with “plant improvement” in recent years. Normally the term plant breeding connotes the involvement of sexual process in effecting a desired change; however, it is also true that modern plant breeding also includes the manipulation of asexually reproducing plants (plants that do not reproduce through the sexual process). Breeding is therefore about manipulating plant attributes, structure, and composition, to make them more useful to humans.

Gepts and Hanock (2006) have defined plant breeding as an applied, multidisciplinary science. It is the application of genetic principles and practices associated with the development of cultivars more suited to the needs of human than the ability to survive in the wild; it uses knowledge from agronomy, botany, genetics, physiology, pathology, entomology, biochemistry and statistics. Of particular importance is the ability to transfer, in addition to major genes, large suites of genes conditioning quantitative traits such as productivity and other traits of interest to humans. The ultimate outcome of plant breeding is mainly improved cultivars. Therefore, plant breeding is primarily an organismal science even though it is eminently suited to translate information at molecular level (DNA sequences, protein products) into economically important phenotypes. The traditional definition of plant breeding includes only those scientists who develop new cultivars and improved germplasm, however, many feel this definition should be expanded to include scientists who contribute to crop improvement through breeding research.

The horticultural produce includes fruits, vegetables, flowers, plantation crops and spices. However, fruits and vegetables are the most consumed and important commodity among them. Morphologically and physiologically, the fruits and vegetables are highly variable and may come from a root, stem, leaf, immature or fully mature and ripe fruits. They have variable shelf life and require different suitable conditions during marketing. All fresh horticultural crops are high in water content and are subjected to desiccation (wilting, shrivelling) and to mechanical injury. Various authorities have estimated that 20-30% of fresh horticultural produce is lost after harvest and these losses can assume considerable economic and social importance.

Maturity

It is the state of reaching a stage of full or advanced development of tissue of fruits and vegetables, after which it will ripen normally. During the process of maturation, the fruit receives a regular supply of food material from the plant and at maturity, the abscission or corky layer formed at the stem end stops this inflow. Afterwards, the fruit depend on its own reserves, and carbohydrates are dehydrated and sugars start accumulating until the sugar acid ratio formation. In addition to this, typical flavour and characteristic colour also develop. It has been determined that the stage of maturity at the time of picking influence the storage life and quality of fruit, when picked immature like mango develop white patches or air pockets during ripening, thus lacks in in normal brix acid ratio or sugar acid ratio, taste and flavour. On the other hand, if the fruits are harvested over mature or full ripe, then they are easily susceptible to microbial and physiological spoilage and their storage life is considerably reduced. Such fruits continue to show numerous problems during handling, storage and transportation. Therefore, it is necessary or essential to pick up the fruits or vegetables at correct stage of maturity to facilitate proper ripening, distant transportation and to obtain maximum storage life.

Introduction

Seasonality in agriculture is a major determinant of poverty, food insecurity and hunger in areas having harvest only once or twice a year. Undiversified livelihoods survive on the crops that the households consume as food and sell for income. The risk being high, a single failed harvest can cause huge losses and can destitute a marginalized household with limited or no savings, increasing their dependence on borrowings leading to indebtedness later on. Punjab being one of the pioneer states in green revolution in country is facing lot of challenges due to monoculture i.e. paddy-wheat as the major crop rotation followed on 92% area of the state. The situation has led to serious repercussions in agriculture sector of the state along with social, financial, and ecological issues. 

Introduction

Age determination, a fundamental discipline within fisheries biology and ecology, is a critical tool for unraveling the life histories and population dynamics of aquatic species. The ability to accurately estimate the age of individual fish holds immense value in various scientific, management, and conservation contexts.

14.1 Introduction

As discussed above, the development discourse on women nationally and internationally moved from Women in Development (WID) to Gender and Development (GAD) and Women's Empowerment. This was reflected in the Government Plans and Policy Documents throughout the past six decades. Since independence, many schemes have been launched for the emancipation of women in the country.

The social welfare method was superseded by the development strategy in the Fifth Five-Year Plan (1974-1979). This acknowledged the contribution and productive role of women. With its emphasis on work, education, and health, the Sixth Five-Year Plan (1980-1985) marks a turning point in the history of women's growth. The Seventh Five-Year Plan (1985-1990) prioritized projects aimed at improving women's status.

Post-harvest management of agricultural crops is a critical aspect of the food supply chain, encompassing a range of activities aimed at preserving the quality and extending the shelf life of harvested produce. The abstract on post-harvest management highlights its significance in ensuring food security, reducing post-harvest losses, and enhancing economic viability for farmers. It emphasizes the multifaceted nature of post-harvest management, which involves handling, storage, processing, and distribution of agricultural crops. The abstract may also touch upon key challenges faced in post-harvest management, such as inadequate storage facilities, pest infestations, and market access constraints. Overall, the abstract provides a concise overview of the importance and complexity of post-harvest management in sustaining agriculture and meeting the nutritional needs of populations globally.

Our digestive structure is not only just a food handle centre. It’s a foundation of fitness, moving everything from our immunity to mental well-being. A fit gut aids in the digesting and assimilation of nutrients supports a healthy and strong immunity, and helps in the effective elimination of waste. Asserting good gut fitness is critical because it can influence our whole body’s health, prevent chronic afflictions, and develop value of growth. Plants have been second-hand for curative purposes for thousands of years, and many up-todate cures are still coming from plant compounds. In this chapter, we will
study some commonly used medicinal plants used to treat common digestive system diseases, along with associated ethnomedicinal details.
1. Diarrohea

The Gujarat state is located on the north-west of India between 20^o6' N and 24^o42' N latitude and 60^o24' E to 74^o24' longitude. The climate of Gujarat is semi-arid tropical . the summers are very hot, the winter season is uncertain and irregular. The Arabian sea and Gulf of cambay have a moderating effect on the climate of the coastal areas of the state.

The state has a coastline of 1600 km (27% of the country) out of which Saurashtra and Kutch has about 1125 km long coastal line. The total coastal cropped area of the state is 8.75 lakh ha (9.11% of total cultivated area) spread over three agro-climatic regions of the state, out of which 91% comes under arid and semiarid climate type (Table 1). The important crops of the region are groundnut, bajara, sorghum, cotton, and wheat. The ground water availability is also scare. In the state recently the soil degradation through salinity has caught hold over 1.2 m ha of land, of which, about 0.3 m ha occurs in the coastal area. About 1125 km long coastal line is in Saurashtra and Kutch which comprises about 0.1079 m ha of saline land which needs to be treated for salinity reduction.
 

Farmer Field School (FFS) is a capacity building method based on adult education principles for group of farmers. FFS is best described as a ‘school without walls’, where farmers learn through observation and experimentation in their own fields. FFS methodology is potential extension approach to enhance farmer’s knowledge which is a basis for adoption of improved practices (Manoj and Vijayaragavan, 2014). In Andhra Pradesh Department of Agriculture initiated FFS programme in the name of Polambadi during 2006.

Introduction

In general economic model, technological change in agriculture is expected to cause the commodity supply curve to shift down and out against a stationary demand curve, giving rise to an increase in quantity produced and consumed, and at a relatively lower price. Agricultural economists have used supply and demand models of commodity markets to represent agricultural research impacts, beginning with Schultz (1953) and Griliches (1958), with important subsequent contributions by Duncan and Tisdell (1971), Akino and Hayami (1975), among others. Such a model is explicitly used in many studies. However, low crop productivity, food insecurity, hunger and malnutrition; inadequate farming knowledge and skills, implements and inputs are characteristic of smallholder agriculture in developing countries including India. Many researchers argue that conservation agriculture can guarantee higher crop productivity, food security, improved net income of the farmers and environmental protection, better than the traditional systems of cultivation practices.

Introduction

Brinjal is an important vegetable crop grown extensively throughout India. In India, brinjal is cultivated in around 730.4 ha with a production of 17.5 million tonnes in the year 2017-18. It is also called as poor man’s vegetable. It is consumed in variety of ways depending upon the eating habits of the different parts of the country. It is grown extensively in Bihar, Orissa, Karnataka, Tamil Nadu, Andhra Pradesh, Maharashtra, West Bengal, Uttar Pradesh and states with matching climatic conditions in the tropics and subtropics.

Brinjal is an important vegetable crop, but insect pests are making more losses in brinjal cultivation. In brinjal, more than 36 pests have been reported from the time of planting to harvest (Regupathy et al., 1997). Among all insect pests shoot and fruit borer (Leucinodes orbanalis), hadda beetle (Epilachna vigintioctopunctata), jassid (Cestius phycitis), Ash weevil (Myllocerus subfasciatus), white fly (Bemisia tabaci), lace wing bug (Urentius hystricellus) are important (Barker and Pritchrad, 1960).

Despite serious nature of the pest, its management tactics by and large is limited to frequent sprays of chemical insecticide without much impact on the yield. Such practice of pesticide usage is detrimental to environment, also increases the cost of production and chances of insecticide residues in the fruit. About 47 per cent insecticides are used for management of fruit and shoot borer out of the total pesticide consumed in vegetables. In this background major emphasis, now-a-days, is being given on Biointensive integrated pest management as alternate to the insecticides for management of any pest. More than a dozen parasitoids and three pathogens have been recorded as natural enemies of insect pest. But the extent of parasitisation/predation under field condition is very low. In this context, inundative release of bio-agents, particularly egg parasitoids in pest management may be more advantageous.

Potato plays a vital role in food security for ever increasing world population (Thiele et al., 2010; Scott and Sourez, 2011; Scott and Sourez, 2012). It is highly capital and labour intensive crop (Kushwah and Singh, 2011). Presently, India is the second largest potato producer in the world. India is producing about 45-48 million tonnes of potato annually from about 2 million hectare of area. However, India would require 125 million metric tonnes of potato from 3.6 million hectare area in 2050 (Vision, 2050). The stagnating growth rates of cereals’ productivity, large scale diversion of food grains to feed & bio-fuel and expected steep rise in per capita consumption of pulses, edible oil, fruits, vegetables, milk, sugar and non-vegetarian food in the regime of steadily rising population is bound to put pressure on existing cultivable land. Since, cultivable land is expected to remain more or less constant in the next 40 years, the role of crops like potato having higher production potential per unit land and time will become imperative. In this context potato crop has very high probability of making crucial contribution to the future national food security agenda. The perceived changes in Indian socio-economics in the medium and long term are expected to enhance per capita food consumption of fresh potatoes.

Fertilizer and nutrient recommendations for different crops are mostly region specific and very general in nature which results into a blanket application of fertilizer leading to its poor efficacy and wastage of costly resources as well as of environmental pollution. In addition, this has caused severe imbalance of nutrients in soil. The spatial variability of available nutrients properly mapped along with other relevant parameters will help to develop site specific nutrient management practices with increased productivity and profitability apart from checking nutrient imbalance and environmental pollution.

Maintaining the required type of information in the form of records is primary for any type of animal breeding analysis and this chapter explains the importance of records and ways to maintain them in the form of registers or computer databases. The formats for different types of registers to be maintained are also given as a template in appendix. Any breeding plan is formulated to improve the economic traits depending on the utility of species reared and the chapter lists important economic traits of livestock and poultry with definitions and formulae, where ever required.

Basic record maintenance is a must for any animal breeding program. Every farm or breeding program is expected to maintain records in the form of registers or computerized databases. The goal of animal breeding is to select mates with the objective to improve economically important traits. In this chapter, the most common economic traits in different species of livestock are described. Even though the list is not exhaustive the basic economic traits that have been worked for improvement are explained. Breeders also explore new composite traits which are a combination of these base traits.

1. Introduction

India’s horticulture sector stands as a beacon of promise and potential within the agricultural landscape, showcasing a rich diversity of fruits, vegetables, tubers, spices, flowers, medicinal and ornamental plants as well as herbs. This sector provides livelihoods for millions of farmers and plays a crucial role in ensuring food security and nutritional well-being. Amidst the challenges posed by climate change and environmental degradation, the resilience of horticultural crops becomes increasingly significant. Diversifying towards resilient crops and sustainable practices not only mitigates risks but also enhances the sector’s adaptability to changing climatic conditions. Investment in research and development to breed climate-resilient varieties and promote agroecological approaches is imperative. Furthermore, promoting organic and niche horticulture products presents exciting opportunities for Indian farmers to capture premium markets both domestically and internationally. With growing consumer awareness and demand for healthy and nutritionally rich food, India’s horticulture sector is well-positioned to become a global leader in organic and exotic produce.The recent trend of exploring new crops within Indian horticulture promises to diversify farmers’ income sources and address emerging challenges such as climate change and shifting consumer preferences.

Reproduction is the backbone of animal production and productivity is the key to development. Reproductive inefficiency is one of the most important causes of economic losses in animal industries and it is realized throughout the world. Despite the remarkable advancement that has been made in the field of reproductive physiology in recent years, infertility due to low conception rate and high embryonic mortality rate remains a major problem. To meet future needs and to be able to sustain agricultural production, agricultural research and its applications need to use all emerging technologies one of which is modern reproductive biotechnologies.5 Thus, various assisted-reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or sub-fertile) animals in addition to disease control. Reproductive biotechnologies intend to be used routinely to shorten generational intervals and to propagate genetic material among breeding animal populations. To achieve this goal, reproductive technologies have been developed in generations over the years, namely artificial insemination (AI), embryo transfer (ET), manipulation of fertilization in vitro (IVF), cloning and transgenesis. These, together with sperm separation techniques, including that of selection of spermatozoa for chromosomal sex (commonly named sex-sorting) all face today a strong wave of increasing commercialization.9 Hence, this review paper highlighted the reproductive biotechnology options and their roles in the improvement of livestock production.
Roles of Reproductive Biotechnology in Animal Production
Biotechnology is defined as a technique that uses living organisms to make or modify and improve products. The emergence and development of reproductive technologies have been driven by the economic gain offered by the potential increase in the number of offspring from genetically superior animals or simply to safeguard the genetic pool of infertile or sub-fertile animals. In other words, reproductive technologies were developed to offer possibilities for wider use of superior germplasm.In recent times, there has been increasing challenges for

Introduction 
Inclusive education means including all children in the same classrooms, in the same schools. It means real learning opportunities for groups who have traditionally been excluded – not only children with disabilities, but speakers of minority languages too. The school and classroom operate on the premise that students with disabilities are as fundamentally competent as students without disabilities. Therefore, all students can be full participants in their classrooms, in the local school community and in the societies they live in. Much of the movement is related to legislation that students receive their education in the least restrictive environment (LRE). This means they are with their peers without disabilities to the maximum degree possible, with general education the placement of first choice for all students (Alquraini & Gut, 2012). Inclusive education in India has evolved significantly over time. Initially, education for children with disabilities was largely segregated, with specialized institutions being the primary option. The shift towards inclusion began gaining momentum in the late 20th century, influenced by global movements and national policies. Key milestones include the 1992 National Policy on Education, which emphasized inclusive practices, and the 2009 Right to Education Act, which mandated free and compulsory education for all children, including those with disabilities. Recent initiatives have focused on improving accessibility, teacher training and integrating students with diverse needs into mainstream classrooms, reflecting a growing commitment to equitable educational opportunities for all. Contemporary inclusive education in India is characterized by a growing commitment to integrating students with diverse needs into mainstream schools, supported by various policies and initiatives. The 2016 Rights of Persons with Disabilities Act and the 2020 National Education Policy underscore the importance of inclusive practices, advocating for accessible infrastructure, specialized training for educators, and individualized support for students. Despite these advancements, challenges remain, including inadequate resources, a shortage of trained teachers, and varying levels of implementation across different regions. Efforts are ongoing to address these issues, aiming to create an educational environment where all students, regardless of their abilities, have the opportunity to succeed and thrive. The emerging importance of an inclusive education system in India reflects a growing recognition of diversity and equality in the educational landscape. This shift is driven by the realization that inclusive education not only promotes social justice but also enhances academic and social outcomes for all students. As India progresses towards a more inclusive society, there is increasing emphasis on
