Introduction

The livestock enterprise is complementary to crop production providing a balance and protective program of farming. Farming that combine’s crop production with livestock rearing is called mixed farming. If cow, buffalo. Poultry, piggery, sheep, goat etc. has more than 10 % contribution to grow gross income of farm is called Diversified type of farming.

Mutagenesis is the process whereby sudden heritable changes occur in the genetic information of an organism not caused by genetic segregation or genetic recombination, but induced by chemical, physical or biological agents.

Mutations were first identified by Hugo de Vries in the late nineteenth century, while experimenting on the ‘rediscovery’ of Mendel’s laws of inheritance. He coined the term ‘mutation’. Radiation-induced mutations as a tool for generating novel genetic variability in plants, advanced as a field after the discovery of the mutagenic action of X-rays demonstrated in maize, barley and wheat by Stadler. The discovery of X-rays by Rontgen in 1895 led to the application of X-rays for inducing mutations in fruit fly by Muller (1927). Mutation is of two types

Introduction

Rice (Oryza sativa L.) is the vital cereal crop, probably the oldest cultivated grain crop, produced under varied ecosystems is consumed as the primary source of food by the billions of people throughout the world covering 9% of total arable land among world. India is one of the top leading countries in the entire world in case of both production and consumption of rice. Rice is cultivated in 43.86 m ha geographical area of the country producing 115.6 million tons (2018- 2019) of rice. It is produced in various ecosystems throughout the country under diverse climatic and soil condition but the productivity is much lower as compared to other countries. According to Pandey et al. (2006), the average loss of rice production during drought years in major rainfed rice grown states like Chhattisgarh, Jharkhand and Odisha was found to be 30 percent of the annual production in case of non-drought years.

Aplant collector and conservationist faces many problems. These include adverse weather, limited availability of personnel, insufficient material because of poor growing season, general scarcity of the plant in the target region, grazing of the plant by animals, damage by pests or diseases or immaturity of the material. These problems are common to both seeds and vegetative propagules. The vegetatively propagated plant material face another unique problem related to excessive weight and bulk. The cost and inconvenience of transporting large amounts of material can be a limitation on the scope of a plant exploration mission. There is additional need to maintain selected clones in a disease-free condition for distribution to national programmes.

Nutrient supply is one of the major inputs for agricultural crop production in a sustainable manner. The factor productivity of inputs especially the fertilizers in agriculture was found to be in a declining phase during the last four decades. This had a detrimental effect on annual compound growth rate of major crops as wells on soil quality. The current status of nutrient use efficiency in different cropping system is low in case of major macro nutrients likes Nitrogen (30-50%) and Phosphorus (15-20%). Because 50-70% of the nitrogen applied using conventional fertilizers, with particle size dimensions greater than 100 nm, is lost to the soil due to leaching, nutrient utilization efficiency (NUE) by plants is low. Attempts to increase the NUE in conventional fertilizer formulations have thus far resulted in little success. On the other hand, the emerging nano strategies indicate that, due to the high surface area to volume ratio, nano fertilizers are expected to be far more effective than even polymer-coated conventional slow-release fertilizers. In this context, nanotechnology offers an important role in improving the nutrient use efficiency of agricultural systems.

Fig along with fruits like date palm, grape (vinifera) and olive was regarded as an important food crop of the ancient civilization that developed in the Mediterranean region. The fig description occurred prominently in number of songs as well as in the mythological and historical events that took place at that time. Fig is thought to be native of southern parts of Arabian peninsula, Italy, Balkan and USSR region. Fig was in cultivation as early as 300 BC and from Arabian peninsula it spread to Turkey, Syria, Iraq and later to many subtropical parts of the western hemisphere.

Feed accounts for a major portion of farm expenses in livestock and poultry production. Thus, to obtain maximum profitability, it must be ensured that the feed should not only be well balanced nutritionally but economical too. Rising prices of feeds certainly have reduced the profitable nature of broiler farming. For better utilization of feed and to improve feed efficiency, antibiotics were used at sub-therapeutic levels in the animal ration.

Development of antibacterials progressed very quickly and as a result, certain new antibacterial substances were discovered and developed for use as growth promoting agents in livestock and poultry. The antibiotics act by reducing nutrient destruction in the intestine, increasing microbial synthesis of certain vitamins and amino acids, reducing the rate of passage of nutrients in the gastrointestinal tract and reducing the thickness of the intestinal wall. This thinner wall and reduced rate of passage have been suggested as factors favoring efficient absorption of nutrients. It is also reported that the antibiotics also inhibit the bacterial production of ammonia and other harmful nitrogenous compounds such as trimethylamine that reduce the growth of chickens.

Introduction

Mithun is to be originated before more than 3000 years ago. Mithuns are found over a large area of southest Asia. This animal’s natural habitat is in the forests of highlands. In addition to meat production, Mithuns are used for sacrificial purposes and also for barter trade. Even today, Mithun is used as a holy sacrificial animal to appease the god by the tribe people. Mithun is a unique bovine species which are situated at limited geographical distribution. It is mainly found in the tropical rain forests of North Eastern hilly states of Arunachal Pradesh, Nagaland, Manipur and Mizoram of India. Mithun is also known as “Cattle of Mountain”. In Indian subcontinents, Mithun is also known as “Gayal” (Bos frontalis). In Myanmar and Bhutan, it is called Mithun, whereas in China, it is called Dulong cattle.

Mithun is a magnificent massive bovine and is presently reared under free range condition in the hill forests at an altitude of 1000 to 3000 m above mean sea level. Mithun plays an important role in the socio-economic and cultural life of the local tribal population. Presently, this animal is mainly reared for meat, which is considered to be more tender and superior over the meat of any other species. Although, Mithun produce less quantity of milk and can be used for preparation of various milk products. Leather obtained from this species has been found to be superior to cattle.

The massive unique beautiful animal is anatomically a physiologically well adapted to high altitude. Mithun is a social animal; they establish small groups usually containing an adult male and several female and juveniles. It is a potential source of delicious meat, and it can also be used for improvement of local, native cattle breeds. Mithun hide has almost three times the size and thickness that of native cattle.

Entrepreneurship involves seeking and exploiting opportunities available for the benefit of the society. The changing agro-economic conditions in our country have offered a prospective context for developing entrepreneurship in agri-business in the country. Agri-entrepreneurship has the prospect of social and economic development, for example, employment generation, poverty reduction, improvements in nutrition, health and overall food security in the national economy especially in rural areas. The task of promoting entrepreneurship was earlier given to different departments and government agencies. In 2014, the Prime Minister decided to dedicate an entire ministry to build this sector as he felt that skill development required greater push from the government’s side. The idea is to reach maximum people and startups through funding and skill development initiatives.

Vitamins are natural and indispensable nutrients that are essential for our bodies in small quantities. Vitamins are indispensable for a multitude of biological functions, including growth, development, wound healing, maintaining healthy bones and tissues, supporting the immune system, and more. These vital organic compounds exhibit diverse biochemical functions and are essential for metabolic processes. The discovery of vitamins dates back to 1912 when Casimir Funk, a Polish American biochemist, initiated research on their sources, functions, and deficiency disorders. Because of his groundbreaking work, Funk is widely recognized as the pioneer of vitamins.

Types of vitamins

The classification of vitamins is determined by their solubility, resulting in two distinct groups: fat-soluble vitamins and water-soluble vitamins.

Fat-soluble vitamins

Fat-soluble vitamins, as their name implies, need fat for absorption and are stored in the fat cells. These vitamins include Vitamin A, D, E, and K.

Balsam (Impatiens balsamina) is an annual herbaceous flowering plant valued for its attractive flowers and use as a loose flower crop. It performs well under warm, humid conditions and is suitable for rainy-season cultivation. The chapter presents its origin, distribution, genetics, botanical characteristics, varieties and climatic and soil requirements. Detailed production practices include seed propagation, stem cuttings, micropropagation, land preparation, nutrient management, planting, irrigation, weed control, mulching, staking and pinching. Plant growth regulators, insect pests and diseases are also discussed. Particular attention is given to harvesting, postharvest handling and yield, making the chapter useful for commercial cultivation and practical floriculture education.

The methods of plant germplasm preservation or conservation depend  upon type of germplasm i.e. seed or non-seed clonal materials. 

Storage of Seeds

According to the storage tolerance of seeds to low temperature and dry environments seeds are further divided into storable (orthodox) and non-storable (recalcitrant) types. The orthodox seeds are those seeds which are fully desiccation tolerant. These basically include small seeded grain crops and vegetables. They can be stored for a long time under low temperature and low humidity environment and are separately stored in long, medium and short term storage conditions in accordance with the purpose of storage.

Abstract

Cut flowers of rose cv. ‘First Red’, with uniform stem length of 45 cm, harvested during different times of the year i.e. March, May and October, were used for standardization of holding solutions to increase the vase life. Harvest-wise pooled averages of two years data (2003-04) revealed that the cut flowers of March and May harvests gave increased flower diameter, more volume of solution consumed, maximum vase-life, reducing sugar and protein content with minimum weight loss when these were held in a solution containing 100 ppm 8-HQC (8-hydroxy quinoline citrate) +1.5 per cent sucrose. For getting similar results of October harvested flowers lower concentration of 8-HQC (50 ppm) with same level of sucrose was found most suitable

Youth, as a concept, has been generally defined all over the world as a group of human beings who have reached the end of puberty but have not yet acquired the full rights and duties of adult life ( Friedman: 1971).  Undeniably, the youth constitute a vast reservoir of energy especially in underdeveloped countries including India. Out of the 120 crores population of India, those in the 15 to 30 age group constitute 50 per cent which means that 60 crore young people, men and women, are available for handling various tasks of development, local, regional and national.  Progress of the country depends on the participation and full involvement of all sections of people especially youth. Youth can make their constructive contribution to national development and through which society can benefit from the idealism and sense of dedication of youth. At the same time, they also benefit from their active participation in developmental activities. Since such participation increases their self esteem, give them a sense of identity and of being needed by society.  The human life passes through various stage such as infancy, childhood, adolescence, youth, adult and old. Out of these stages the youth stage is very crucial and dynamic in the life of an individual as from this stage individual starts assuming responsibilities in the life and learns practically the social rules by coming in contact with world outside the family.  Youth is the time of life marked by growth and development. It is the period between childhood and maturity. United Nation has defined youth as those young people within the age group of 15 to 24 years both inclusive. Youth symbolizes zest, idealism, dynamism, enthusiasm and energy.

Afamous traveller John de Marignolli has described jackfruit as ‘there is again another wonderful tree, which produced fruit on the trunk, and was very pleasing to see and the fruit was as big as a lamb‘. The rind is hard and has to be cut open by a sharp knife, the pulp inside is of pleasant flavour sweetness of which matches the honey and usually contains 500 or more chestnut like seeds which are eaten after roasting. In its place of origin (India) where it has been grown since ancient times it is held in great esteem. Theopharatus and Pliny who wrote about jackfruit also expressed similar opinion about the fruit. In India several vernacular names are given like Kanthal, Kathal, Panasa and Kantaka.

Introduction

A hatchery is such a facility where eggs are hatched under artificial conditions, especially those of poultry eggs. Poultry hatchery produce a majority of bird’s chicks by hatching their eggs including chicken, turkey, ducks, quails, goose and some minor bird species. A broiler breeder produces about 150-180 fertile eggs in a year of reproductive life. This reproductive capacity can’t be utilized without liberating the breeding hen from incubating eggs. In India, there is huge demand of day old chicks for commercial poultry farming and for that there is great scope for hatchery business. The competition in the hatchery industry is increasing day by day for efficient production of quality chicks economically. Therefore, it may be necessary for the hatchery man have thorough understanding of the basic and practical aspects of incubation and hatchery operation for efficient working.

Disease Forecasting

Definition

Forecasting involves all the activities in ascertaining and notifying the grower of community that conditions are sufficiently favourable for certain diseases, that application of control measures will result in economic gain or on the other hand, and just as important that the amount expected is unlikely to be enough to justify the expenditure of time, energy and money for control. The above statement made explicit distinction between positive forecast and negative forecast and both have value for growers as well as society in general.

Positive forecast: Employs need based chemical sprays, provides adequate protection to crop and reduces damage to environment.

Negative forecast: Avoids unnecessary chemical sprays, no risk to the crop health and no disruption of environment.

Soil organic matter is a key component of soil fertility, biological activity, aggregation and carbon storage. This chapter examines the origin, transformation and management of organic matter in agricultural soils, with particular attention to irrigated agroecosystems. It discusses the decomposition of organic matter under aerobic and anaerobic conditions and explains the major factors influencing decomposition rates. Microbial activity plays an important role in transforming organic materials and regulating nutrient cycling within the soil. The chapter introduces humus, humic substances and non-humic substances and explains interactions between clay and humus that influence soil properties. The relationship between soil organic matter and plant growth is also considered, highlighting its contribution to nutrient availability, soil structure and biological processes. Methods for maintaining soil organic matter and conserving soil carbon in agroecosystems are discussed along with factors controlling soil carbon levels. The chapter therefore establishes the importance of organic matter management for improving soil health, carbon conservation and the long-term sustainability of irrigated agricultural systems.

Abstract

The effects of packaging materials, temperature and dressers on bell pepper (Capsicum annuum, L.) seed storage, at the end of 24 months, revealed maximum test weight (5.15 g) in poly jar x refrigerator x cow dung. Maximum seed germination was observed in polythene bag x refrigerator x thiram. This combination resulted in slow but gradual decrease in germination from 3rd month (95.33%) to 24th month (75.33%). The same combination of treatments also extrapolated maximum SV-I (15-24 months) and  (Seed Vigour)SV-II (18-24 months). Stress test was maximum (50.01%) in poly jar x refrigerator x thiram. Thus, it was inferred that bell-pepper seed germination and vigour can be maintained for 24 months after treating the seeds with thiram, packing in polythene bag and then storing in refrigerator, after harvesting the crop.

1. HETEROSIS

1.1. Definition

Heterosis or hybrid vigor or outbreeding enhancement, is the increased function of any biological quality in a hybrid offspring. It is the occurrence of a genetically superior offspring from mixing the genes of its parents.

1.2. Inbreeding depression

Inbreeding depression is the reduced fitness in a given population as a result of breeding of related individuals. In general, the higher the genetic variation within a breeding population, the less likely it is to suffer from inbreeding depression.
