Introduction

Climate change induces significant and long-lasting shifts in the statistical distribution of weather patterns over periods ranging from decades to million years. It is believed to be the cause of long-term temperature changes, changes in rainfall patterns and volume, prolonged summer seasons, increasing sea levels, and increased frequency and intensity of floods, droughts, and heat waves, etc.

Animals are intimately and inseparately associated with their physiological and chemical environments from conception until death. As a result, climate change has an impact on animals both directly and indirectly. Since, animals have had to alter their behavioural and physiological mechanisms in order to maintain homeostasis.

Climate change has emerged as a serious threat to the livestock industry. It reduces animal productivity by lowering growth, milk yield, meat production, egg production, wool production, reproductive performance, and health. About 20 to 30 percent of plant and animal species would likely be at risk of extinction with an increase of 1.5 to 2.5°C, which will result in severe consequences for food and nutritional security in developing countries. This is why; measurements of meteorological variables are needed for effective scientific management of livestock and poultry to cope with the negative impacts of climate change while enhancing growth and productivity.

Estimation of variance is primary for any breeding program as all the genetic parameters are dependent on these estimates. The properties of an estimate, their assumptions, type of data, availability of data, and computational requirement make it important to understand the method of estimation of variance components so as to make a wise choice that would suit the breeder’s requirement. This chapter explains the methods of estimation of variance with merits and demerits of each and the reader could use these as a guide to choose the right method of estimation.

The genetic parameters are the basis for any animal breeding program and the important parameters such as heritability, repeatability and genetic correlation are ratios of (co)variances and their reliability depends on the accurate estimation of variance components. Estimates of variance components are used extensively in animal breeding.

Introduction

The kidneys play a vital role in maintaining water and electrolyte balance (such as chloride, potassium, calcium, hydrogen, magnesium, and phosphate ions). It also regulates the acid-base balance of the blood, arterial blood pressure, and osmotic pressure of the nd water-soluble waste products, which are removed from the bloodstream by the kidneys and excreted as urine. Normally, the kidneys receive about 22% of the cardiac output. According to Arthur Cushny (1866-1926), there are three steps involved in urine formation in the nephrons: glomerular filtration, tubular reabsorption, and tubular secretion. When the kidneys are injured, their regulatory activities are disrupted, resulting in a change in the quality and quantity of urine. Urine is composed of the following components:

This is the reason why a urine analysis is a common test to evaluate the pathophysiology of the urinary system in general and the kidneys in particular, as well as to aid in the differential diagnosis of certain diseases.

Services for CSA

Under the CSA projects and programmes, the services like supply of inputs and technology transfer through extension services are provided to the farmers. The inputs like seeds of crops are provided by the input dealers at the subsidized rate and seedlings of fruits and vegetables are provided by both private and government agencies to grow under general cultivation and poly-house cultivation technology. Similarly other services like soil testing facilities, issue of soil health cards, construction of micro-irrigation projects and rain harvesting structures are made available to farmers. Under insurance scheme, loanee farmers are supported to pay premium dues for availing crop insurance facilities. Other services like trainings at various levels, demonstrations, exposure visits, exhibitions, kisan melas, field days, monitoring and evaluation of all these activities under these programmes are provided to the farmers with collaboration of extension officers.

Introduction

Ficus carica is widely distributed in tropical and sub-tropical countries. The related genera with edible fruits are Artocarpus, Cudrania and Morus of the family Moraceae. Some important species are Ficus glomerata, Ficus bengalensis, Ficus religiosa, Ficus elastica, Ficus hispida and Ficus roxburghii. A fig is a large shrub or low-growing deciduous tree with a short and twisted trunk. Fruits are solitary, axillary green or yellow, pear-shaped.

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.

Approximately 80 per cent of all flowering plant species are specialized for pollination by animals and mostly by insects. These crops account for 65 per cent of global food production, still leaving as much as 35 per cent depending on pollinating animals (Klein et al., 2007). These food crops include delicious products such as many of our tree fruits (e.g., apples, cherries, mangos, and avocados) and nuts (e.g., almonds, peanuts, macadamia nuts, and cashew nut), squashes, cucumbers, melons, citrus, and berries. In addition, many of oil seed crops benefit from bee pollination, such as mustard, coconut, canola, safflower, and many more.

The honey bee (Apis mellifera) is the most commonly used insect in agricultural crops as managed pollinator in North America and Europe, Japan, China, India and many other parts of the world as well. Farmers in the United States rent more than 2.5 million honey bee colonies every year for fulfillment of pollination deficit but today, the honey bee is threatened by colony collapse disorder (CCD). The demand for honey bees in California almond orchards rapidly increased due to increasing acreage, while on the other side, bee colonies decreased due to CCD, but that occurred during a time when honey bee colonies were not easy to procure and as a result, the cost of renting bees shot up from US$50 per hive in 2003 to US$140 per hive in 2006 (Sumner and Boriss, 2006). The rental charge increased about 3 times within 4 years.

The key genetic parameters available with the animal breeder to attain improvement are heritability, repeatability and genetic correlation. This chapter will mainly deal with the theoretical considerations of these parameters.

The goal of an animal breeder is to bring about permanent improvement in different economic traits, either individually (univariate) or simultaneously in multiple traits (multitrait). The phenotypic value available from the animal is a combination of genotypic value and environmental deviation. By permanent improvement in a trait, we mean the improvement in genotypic value, which could be carried over to future generations. The environmental deviations are spatially and temporally specific, and thus will not be the same over generations. The genotypic value, itself is made up of additive effect, dominance deviation and interaction deviation. The additive effect is a value of genes (the sum of the average effect of genes) and hence is more important for the breeder as only the genes are passed on to the next generation.

Introduction

Grapes are a delicious, refreshing, and nourishing fruit. It was introduced into India by the in values of Iran and Afghanistan. 50% of the total production of fruits in the world is contributed by grapes. Cultivation of grapes is called “viticulture”. Easily digestible and rich in energy-giving sugars, certain minerals and vitamins. Grape juice is a refreshing drink a stimulant to kidenys and laxactive. In India, 80% of the production is used for table purposes, 10% for raisins and 10% for wine production, while in western countries 80% is used for winery, 10% for raisins, and 10% for table purposes. The area of the same is increasing fast in Maharashtra, Karnataka, Mizorum, Andhra Pradesh, Tamil Nadu, Punjab, Haryana, Madhya Pradesh and Uttar Pradesh are grape growing.

Introduction

Guava ranks 4^th in area and production after mango, banana, and citrus. It is a very hardy sub-tropical plant, prolific bearer. It is known as the “poor man’s apple” in India and has spread widely throughout the country. Allahabad has the reputation of growing the best guava in the country as well as in the world. A native of tropical America, guava was spread rapidly throughout the world’s tropics by the Spanish and Portuguese. The major guava producing countries are India, China, Thailand, Indonesia and Pakistan. In India, it is grown in Uttar Pradesh (largest area and production), Bihar, M.P, Maharashtra and Andhra Pradesh. The fresh fruits are very rich in vitamin C (100-260 mg/100 g pulp). Vit-A, B and minerals like Calcium, P, acidity 2.4 per cent, carbohydrates 9-10 per cent, TSS-13 per cent, pantothenic acid, riboflavin, thiamin and niacin, also a rich source of pectin. The fresh ripe fruits are used as table/salad fruit. Fruits are rich in pectin. The best quality jelly can be prepared.

Introduction and Origin

It is typically a temperate zone nut crop and is mostly grown in Turkey, Italy, Spain, Germany, France and England. Turkish hazelnut production of 625,000 tons’ accounts for approximately 75 % of worldwide production. The common hazel (Corylus avellana) is native to Europe and Western Asia. In Himachal Pradesh, it is found growing wild in the Pangi region of Chamba district, where it is locally known as Thangi. Hazelnut is also known as cobnut and filbert. In the UK, a distinction is made between filbert, which has a husk longer than the nut, and cobnut, in which the husks are shorter than the nut. Hazelnuts are extensively used in confectionary to make praline and are also used in combination with chocolate truffles.

Climate and Agriculture

Soil, climate and water are three basic requirements of a crop to be grown in a particular region. Climate affects the temperature trends, seasons, length of the growing season, amount of sunlight and the seasonality of sunlight etc. A change in climate may cause recurrent droughts, floods and weather extremities that would affect the agricultural production, human livelihoods, health and biodiversity. The relationship between agriculture and climate is complex as it is dependent on climate and also plays a contributing role in emission of greenhouse gas (GHG). Greenhouse gases include carbon dioxide, nitrous oxide, methane, chlorofluorocarbons (CFCs), hydro-chlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), per fluorocarbons (PFCs) etc. , which play a significant role in climate change.

In agro-ecosystem, many agricultural and horticultural crops are dependent on insects for their pollination; their degree of interdependence varies species to species. Some plant species depend primarily on a single pollinator’s species or genus, whereas some plant species accept diverse pollinators. About to 80 per cent of flowering plants’ pollination determined for pollinators (FA0, 2007) and out of that most of the floras depend on insect pollinators for pollination and pollinators depend on flora for their food. Bees are considered as most important pollinator due to their diversity, credential ability and effective pollinators of many plant species. Most of the crops pollination need was met by wild pollinators living within the farming landscape (Kevan and Phillips, 2001). Therefore, pollinators play paramount role in ecosystem through enhance the crop productivity and conserving biodiversity. On the above service of pollinators is priceless and natural endowment, but the society we live in, always categorized and measured in terms of financial value. In 2005, globally, insect pollination services economic value was estimated to be about €153 billion (Gallai et al., 2009). The United Nations also reported that the economics of ecosystems and biodiversity by insect pollination was valued at £134 billion. The assisted pollination may have to be done when natural pollination is insufficient in order to reduce potential yield loss (Klein et al., 2007).

Agricultural biodiversity is known as crop genetic resources, although agroecosystems hold a wide diversity of other organisms that contribute toward their productivity and sustainability. Amongst these pollinators play the massive role in crop pollination and thus ensure that fruit or seeds are formed. Over 3 decades ago, the international community began to emphasize on the importance of pollinators. In agro-ecosystems, pollinators are essential for agriculture, horticultural and forage production as well as the production of seed for many root and fiber crops. Pollinators such as bees, birds and bats affect 35 per cent of the world’s crop production, increasing outputs of 87 of the leading food crops worldwide, plus many plant-derived medicines in our pharmacies (Klein et al., 2007). Food security, food diversity, human nutrition and plant diversity all rely strongly on animal pollinators. Pollination is an essential ecosystem service that enables plant reproduction and food production. The pollinators’ abundance and diversity play pivotal role for enhancement of the productivity, quality and maintenance of natural resources of plant biodiversity. The diminution of pollination abundance and their diversity certainly affect productivity, quality and plant biodiversity.
