1. Introduction

Poultry industry in India stands out as a major success story. It’s phenomenal that India’s poultry production whichstarted justas a backyard venture before 1960s, has shaped up into a proven agribusiness, where its annual turnover exceeds Rs 30,000 crores. Current global ranking of India is that of number three, in terms of egg production (behind China [1st] and USA [2nd]), and of18th position in Broiler production. Today, Poultry is one of the fastest growing industries of the agricultural sector in India at present. The annual growth of broilers and egg production is 8-10% compared to 1-2% for production of agricultural crops [3].

Poultry production forms an important Agrarian Avenue providing valuable animal proteins for the fast-growing human population of the developing India, with promises of additional income to small and marginal farmers.Rural and backyard poultry farming is very common among landless and marginal farmer families in India and is a rewarding source of additional income. It involves low investment with high returns which can be easily operated by women, children and elder members of the farm families. Poor households generate good income through backyard poultry farming which provides meat and egg rich in protein and energy. Agriculture including animal husbandry provides 30-40% employment in terms of man/woman days in a year. Scarcity of land holdings, land fragmentation and seasonal agriculture aresome of the reasons that crop production only is unable to provide cent percent employment to the rural youths (men and women).

The sheep population in India is estimated to be about 65.07 million ranking second in the world (Anonymous, 2019). There are 42 descript breeds of sheep distributed in various agro climatic zones of the country (Anonymous, 2017). It is well-known that the sheep rearing provides nutritional security and insurance to the farmer at the time of crisis due to crop failure. Therefore, sheep is seen as, “finance elevator” by the countryside poor farmer (Sharif et al., 2011). Two major sources of income; meat and wool make sheep industry a very profitable enterprise. In addition, a rich source of nitrogen, phosphorus and potash present in the droppings of sheep improves the soil fertility. Indian sub-continent isa rich source of diverse ovine germ plasm.
The native breeds of sheep of from India are well adapted to geo-physical and agro-climatic conditions. Most of the breeds of sheep in India have evolved through natural selection. Most of the breeds have generally been named after their place of origin and on the basis of prominent characters. This vast ovine biodiversity in India is being eroded rapidly and more than 50% of sheep breeds are currently under threat.
Sheep biodiversity in India is characterized by high degree of endemism and variations in agro-climatic conditions of the different regions have led to the development of various breeds/strains. Selecting for breeding animals with superior EBV in growth rate, meat, milk, or wool production, or with other desirable traits has revolutionized livestock production through out the world.
Breeding means, the manner in which selected males and females are mated. The breeders identify and select desirable qualities in animals for future mating and discard less desirable qualities. For the improvement of livestock (farm animals) selection and breeding must be practiced simultaneously. Continuous selective breeding leads to homozygosity in a population resulting in loss of variability. If all the individuals are alike, the breeder cannot make progress in future. Hence, there is a need to create variability in population. This can be achieved by breeding. Therefore, selection and breeding go hand in hand for the improvement of livestock.

Soil  and its Components
Soil
Soil is a three dimensional, transferable natural material which is found on the earth crust and provides natural medium to plant growth. OR
Soil is the upper most loose layer of the earth, suitable for plant growth. 
Different scientists defined ‘SOIL’ in different ways:
Buckman and  Brady defined soil as  “A dynamic natural body on the surface of the earth in which plants grow, composed of mineral and organic materials and living forms”.

In the foregoing experiments performed either in CRD or RBD or LSD. We were primarily concerned with the comparison and estimation of the effects of a single set of treatments like varieties of paddy, different methods of cultivation etc., and such experiments which deal with one factor only may be called simple experiments. In factorial experiment the effects of several factors of variation are studied and investigated simultaneously in a single experiment, such experiments are known as factorial experiments. In these experiments an attempt is made to estimate the effects of each factors and also the interaction effects i.e. the variation in the effect of one factor as a result to different levels of other factors.  These experiments provide an opportunity to study not only the individual effects of each factor but also interactions.  In many biological and clinical trials factors are likely to have interaction. Therefore, factorial experiments are more informative in such investigations.

Lagerstroemia indica belongs to family Lythraceae commoly known as Crape myrtle. It it grown well in India for various landscape purposes. It is called Sawani or Shravani (Hindi), Dhayti (Marathi), Chinagoranta (Telugu), Pavalakkurinji (Tamil). Lagerstroemia a long period of striking rainy season flower colour, attractive fall foliage and good drought-tolerance all combine to make a favourite shrub or small tree for either formal or informal landscapes. It is a deciduous, multi stemmed; rounded crown; dense branching and is highly recommended for planting in urban and suburban areas.

The scientific name, Lagerstroemia, was coined in 1759 by Carl Linnaeus, who described and named the plant in honour of “Magnus von Lagerstroem”, an avid naturalist and director of the Swedish East Indies Company. Crape myrtle derives its common name from its crepe-like, crinkled petals, and the resemblance of its leaves to the true myrtle, Myrtus communis. “Crape myrtle” is a peculiarly-American term. Elsewhere in the world, “Lagerstroemia” is often used as the common name for crape myrtle (Knox, 2003).

Crape myrtle is the smaller version of Lagerstroemia speciosa, commonly known as Pride of India or Queen crape myrtle. The deciduous crape myrtle is among the longest blooming trees in existence with flowering periods lasting from 60-120 days. Crapes come in heights as short as 46 cm and as tall as 12 m. Leaves are alternate and smooth, but leaf size depends on variety. Flowers are borne in summer in big showy clusters and come in white and many shades of pink, purple, lavender and red. The bark is a prominent feature being smooth, pinkinsh-gray and mottled, shedding each year. Leaves are small and dark green changing to yellow and orange in autumn. When the leaves fall in winter, crape myrtle becomes a living sculpture. The trunk and branches of tree-form plants have an attractively gnarled, sinuous character with smooth bark. Seeds are narcotic. In Manipur, flowers and leaves are used as purgatives. Bark is stimulant and febrifuge (fever removing). Roots are astringent and used as gargle.

A review on historic occurrences of tsunamis in the Indian Ocean and their associated characteristics followed by detailed characterization of genetic causes of recent tsunamiarepresented in this chapter. Althoughsubmarineearthquakes occur very frequently, resultant tsunami and its strength relied on many factors including transformation of energy into the ocean water, area of rupturing of ocean floor, duration of rupturing, accompanying submarine slides, kind of material at focus of earthquakes and type of faulting. The direction of tsunami wave propagation plays the decisive role in deciding sites of impacts. Perfect blend of all these parameters is required to make a submarine earthquake to generate devastating tsunami, which is relatively rare in geological history. This is the reason why although there were as many as 77 tsunamis that occurred in the Indian Ocean region during historic past, the recent one of 26th December 2004 is deadly and rare geological occurrence. However, aftermath effects in terms of volcanic eruptions, coastal high wave activities and change in climatic cycles are recorded since then and require constant scientific vigil.

INTRODUCTION

Tsunami is defined as a sea wave of local or distant origin that results from large-scale seafloor displacement associated with major earthquake or submarine slide or submarine volcanic explosion. Many a times it is incorrectly described as tidal wave or seismic sea wave, as both of these terms mislead in regard to its mechanism of generation. In Tamil Sangam literature, tsunami is cited as “Azhipperalai”. In South America, it is termed as “Maremoto”. Other names for tsunami include “Flutwellen”, “Vloedgolven” “raz de mare” “Vagues Sismique” and Kai e’e. Prevalence of specific terms for tsunami in many such regions and languages itself stands testimony to the fact that tsunami is known to ancient human populations and that tsunami occurred frequently the historics past.

Women Folk: A Precious Resource

India’s ancient history ascribes a divine status to women. Laxmi, Durga and Saraswati are the three great goddesses of Prosperity, Power and Wisdom respectively. The ancient scriptures declared that ‘God lives where women are worshipped’. However, a multitude of derogatory attributes have been ascribed to women in the post-vedic period. According to Manu, “a woman must never be independent. In childhood, she must be subject to her father, in youth to her husband, and when her lord is dead, to her sons”. The passive role of women, unfortunately thus visualized, later guided the future course of action leading to their present status of backwardness in general and neglect in the streams of development and scientific arena in particular.

The term ‘gender’ was first used by Ann Oakley and others in 1970s to describe the characteristics of men and women which are socially determined in contrast to biological differences. The term ‘gender’ further explains, a neutral term meaning either men or women or both in a particular context. The goal is to improve the status of disadvantaged class and get rid of socially created and approved discriminations. The green revolution in India changed the face of agriculture but apparently it contributed to two general trends (FAO, 1996) where wealthy have benefited more from technological change in agriculture than the less well off andsecondly men have benefited more than women.

The major concern of fisheries and aquaculture is to reduce the widening gap between fish demand and supply and achieve the ultimate goal of self-sufficiency in fish production; however, this can only be achieved if technology advances. The world's fishery resources require scientific management to preserve their long-term viability and availability for future generations. Overfishing and its detrimental effects on ecosystems have become increasingly evident in recent years. Recent developments in fishing technology have focused on reducing the bycatch of non-target species, protected species, and juveniles, minimizing the environmental impact of fishing gear and their operation, and minimizing the energy use per unit volume of fish landed during fishing operations. Fishing innovations have been around for thousands of years, and they were primarily motivated by the goal of enhancing capture efficiency, which was sparked by a growing comprehension of the habits and behaviors of the species that were being sold. The degree of adoption of responsible fishing technologies strongly depends on the robustness of the fisheries management system.

Persimmons are mainly distributed in tropical and subtropical regions of the world. The genus contains nearly 400 species including the horticulturally important, Diospyros kaki, D. virginiana and D. lotus. The persimmon cultivated mainly for fruit is D. kaki, which is called the Japanese persimmon, Oriental persimmon, or simply Kaki. The generic name is derived from the Greek ‘dios’ (meaning divine) and ‘pyros’ (meaning grain of wheat), referring to the excellent fruit of the genus. The specific name kaki is from the Japanese common name given by Carl Peter Thunberg (1743–1828), a Swedish naturalist and medical doctor, and a pupil of Linnaeus. He stayed in Japan from 1775 to 1776 and published “Flora Japonica” in 1784 introducing many Japanese plants.

Introduction

Agricultural pests cause considerable yield losses throughout the world. In ancient times, farmers had to manage pest problem to safeguard their basic needs, and as a response, the farmers use to practice and develop cultural and mechanical pest control strategies based on their field experience. Over a period of time, these practices have become a part of their production management system. Pest management practices began to change in later stages of the 18^th century. Introduction of pesticides in agricultural ecosystems 1950’s contributed substantially in raising agricultural productivity and they become an integral component of intensive agricultural ecosystems. At the same time, environmentalists raised their concerns on deleterious effects of pesticides on environment, human health and non-target organisms. Excessive use and abuse of pesticides leads to the problems like resistance, resurgence and residues (Beaument, 1993). One of the deleterious effects of over use of pesticides is the death of effective predator and parasitoids. This ultimately leads to the imbalance in the agroecosystem. Concerns about the negative effects of pesticides led to research and promotion of alternative pest control practices – Integrated Pest Control or simply IPC. This new concept called Integrated Pest Control (IPC) and later Integrated Pest Management (IPM) was stimulated by symposia organized by the Food and Agriculture Organization (FAO) of the United Nations in 1966 and the International Organization for Biological Control (IOBC) in 1967. IPM made a paradigm shift in the philosophy of pest control, from pest eradication to pest management. Instead of single tactic control, emphasis was placed on the use of a combination of available tactics in a compatible manner keep the pest below economic injury levels. Consequently, a more integrated approach of pest control was advocated considering the natural mortality factors. IPM is a complex system approach that comprises judicious use of cultural, physical, mechanical, biological, host plant resistance, regulatory and chemical methods.

8.1 Introduction

One important aspect of bio-aesthetic planning is to landscape public places on a priority basis compared to private places. For this specific reason, the railway station and the railway lines should attract attention at the very outset for landscape gardening.

8.2 Definition

Bio-aesthetic planning means the proper utilization of the available flora and fauna in the beautification of the surroundings. The concept of bio-aesthetic planning is given by concept of Prof. Lancelot Hogben.

In India, the theme of bio-aesthetic planning was propagated by Dr. M. S. Randhawa. Le Corbusier and his associates, Pierre Jeanneret, E. Maxwell Fry and Jane B. Drew had planned Chandigarh city as per the principles of bioaesthetic planning.

Introduction

Banana (Musa sp; family: Musaceae) is the most popular commercial soft fruit crop grown in equatorial and subtropical regions of the world and also serves as a staple food since the dawn of recorded history in many countries (FAO, 2012). It has bounties of significance to the human beings and is one of the 4th most important food in the world after rice, wheat, and maize. Musa species grow in a wide range of environments ranging from the edible bananas and plantains of the tropics to cold hardy fiber and ornamental plants. They thrive well in an average annual temperature of 20^°C and well distributed rainfall of 200 cm per year (Simmonds, 1959; Wardlaw, 1961). Banana is a large, perennial, monocotyledonous herb 2-9 m in height that arises from large, subterranean rhizomes called ‘corms’. Musa fruits are variable in size, shape, and color. They are generally elongate cylindrical, straight to strongly curved, 7-40 cm long, and 2-8 cm in diameter. The fruit apex is an important attributes in variety identification.

India is the home to a number of fruit species including mango, banana citrus etc. which have global importance. The North-Eastern (NE) region is particularly endowed with tremendous diversity of banana and citrus and a number of wild/ minor species. However, India has been and continues to be highly interdependent for germplasm sharing with many countries. In the early times, development in Indian fruit industry brought about largely by making selections from indigenous variability for large scale production. Selection from natural or introduced diversity was performed by the local growers, often patronized by rulers, continued over the years and resulted in the development of several popular types of different fruits.

14.1 Introduction

Sugarcane, basically a tropical crop in nature, requires a suitable high temperature, a lot of sunshine and rainfall ranging from 1250-2500 mm for its growth and yield. Relatively speaking, it is an intensive user of water as compared to rice and other crops. The total water requirement to mature the crop is about 64-80 acre inches.  Although globally but Brazil and Mexicos in Americas, India, Pakistan, Thailand and China in Asias, Australia and Africa, the Caribbean and to a smaller degree in southern Europe and the Middle East are major sugarcane growing areas in the World (Khan and Jamil, 1983). Historically famous for sugar, this crop has now attained a significant nadir for biofuel production (Mino, 2010).

Sugarcane, a perennial grass, is exposed to all sorts of biotic and abiotic adversaries. The variation in weather parameters like sunlight, temperature, rainfall, humidity and solar radiation affect the different phases of growth like germination, tillering, cane formation and cane stalk elongation, as well as the maturity and ripening phases of plant (Malik, 2009).

Abstract

Abundant organic wastes come from agriculture sector. Earthworms offer an opportunity for beneficial disposal of this unwanted material by converting into vermi compost, a national wealth. It is rich in nutrients, enzymes, hormones and beneficial microbes but free from harmful chemicals and pathogenic microorganisms, hence improves crop productivity. Disposal through burning creates environment pollution and loss of valuable plant nutrients. Dumping creates unhygienic situation. Vermicomposting is quicker than other conventional composting techniques. In northeast India, Eisenia foetida and Perionyx excavatus were found equally efficient in vermi composting of agricultural wastes. Among different bio mass, vegetable wastes and soft weeds were converted to compost very quickly by using Perionyx excavatus within 1 to 2 months. Composting was found moderate (3 to 4.5 months) in crop residues and hardy weeds while slow (5 to 10 months) in case of dry tree leaves. When different wastes are mixed together it takes 3.5 to 4.5 months for complete composting. Composting can be accelerated by mixing the wastes with cellulolytic fungi such as Triichoderma viride, Trichurus spiralis, Paecilomyces fusiporus and Aspergillus awamori. Vermicompost prepared from wastes is a marketable product. It can bring prosperity in the villages by means of employment generation and good income. Awareness among people can be created through training.

Cymbidium is a genus in the orchid family Orchidaceae. It was first described by Olof Swartz in 1799. The name is derived from the Greek word “kumbos”, meaning “hole”, “cavity”. It refers to the form of the base of the lip. The flowers are long-lasting, both on the plant and when cut large attractive and available in a wide range of colours. Smaller plants are now coming into vogue as decorative pot plants. These have smaller flowers but they are as desirable as the standard varieties and often more acceptable in modern homes. The popularity of miniature cymbidium is now spreading from Asia to the worldwide orchid community. These ancient flowers have been treasured in numerous societies for nearly two thousand years. Many orchid lovers are most charmed by its fragrance and form rather than its petite size.

Cardiovascular examination provides essential information about cardiac function, circulation and vascular abnormalities. This chapter describes practical examination techniques including inspection, palpation, percussion and auscultation of the heart and peripheral circulation. Assessment of the cardiac impulse, heart sounds, murmurs, pulse quality, jugular veins and blood pressure contributes to identification of cardiovascular abnormalities. Electrocardiography is presented as an important diagnostic technique, including electrode placement and interpretation of standard leads. Echocardiography is also introduced for structural and functional cardiac assessment. The chapter provides species-specific practical approaches for cattle, horses and dogs, helping veterinary students recognize cardiovascular abnormalities systematically and accurately

Introduction

Training is the crucial and expensive component of HRD, intended to improve the efficiency and effectiveness of performance of the members of organization through planned learning efforts, transfer of such learning at work place and in turn improvement of the organizational performance. Given such objectives, most of the training programmes fail to inculcate the transfer component in trainees (Subedi 2004). Hence, there is an increasing concern over training transfer at work place and the resultant improved organizational performance in terms of productivity, efficiency, effectiveness and turn over etc (Howard 1995, Huselid 1995, Martocchio and Baldwin 1997 and Salas et al.. 2000, Thayer1997).

Introduction

India has about 18% of the human and 15% of the livestock population of the world that needs to be supported from only 2% of the earth’s land area. The per capita land availability has declined from 0.89 ha in 1951 to 0.37 ha in 1991 and is likely to be 0.20 ha by 2035 (Singh, 2005). It is estimated that demand for green and dry fodder would be short by 64 and 24% by 2020, while it was short by 62 and 22% in 2005. The current sustainable production of firewood is 17 million tons from forest areas and 98 million tons from non-forest areas, leaving a net deficit of 86 million tons which is removed illicitly from forest and scrub formations all over the country. Nearly 32.67% of India’s geographical area is affected by various forms of soil erosion and land degradation. The area reported to be degraded in India varies widely, ranging from 63.9 million ha (Anonymous, 2000) to 187.70 million ha (Sehgal and Abrol, 1994), due to variations in approaches used to define degraded lands. The area under wastelands is estimated to occupy 63.85 million ha which is 20% of the country’s geographical area.

This chapter provides an introduction to cyclogenesis, nature of cyclone disaster and historic events. The mechanism that is in practice in cyclone mitigation, information dissemination and relief and rescue operations are detailed. As the state of Orissa is being battered more frequently by cyclones than any other state of India, special emphasis on cyclone disaster management system of Orissa is also discussed.

INTRODUCTION

Orissa state with immense natural resources is located between 17⁰27’N and 22⁰34’N latitudes and meridians of 81⁰27’E and 87⁰29’E longitudes. Orissa lies on the eastern coast of India with the waters of the Bay of Bengal swirling along its eastern and southeastern boundaries. It shares its boundaries with West Bengal and Jharkhand on the north, Chattisgarh on the west and Andhra Pradesh on the south. Out of the Indian mainland coastline of 7500 km, it constitutes a coastline of about 480 km. It extends for about 155,707 sq.km accounting about 4.74% of the total area of India. According to the 2001 census, it has 3.57 percent of the total population of India. Administratively, it has 30 districts, 3 Revenue Divisions, 58 Sub- Divisions, 51,061 villages and 127 Urban Centers.

Based on physiography, Orissa can be divided into three broad regions - the coastal plains, the middle mountainous region and the plateaus, and rolling up lands. The coastal plains extend from the River Subarnarekha in the north to the River Rushikulya in the south. The coastal zone covers nine districts namely Ganjam, Puri, Jagatsinghpur, Kendrapara, Jajpur, Khurda, Cuttack, Bhadrak and Balasore. It is narrow in the north, widest in the middle, narrowest in the Chilika coast and broad in the south. The coastal belt of Orissa lacks hills excepting few hillocks and mounds in the northern and southern parts. It has extensive low lands adjacent to the sea, sloping gently towards the shoreline of the Bay of Bengal. The coastline consists of the lakes, lagoons, marshes, bays and islands and natural harbors. The lakes in Orissa are natural and artificial. One of the blazing example of the natural lake is the Chilika lake.There is only one bay in Orissa which is the Hukitola bay. Eventually there are only two islands in Orissa - the Short’s Islands and the Wheeler Islands. Among the natural harbor, there is only one of its type in Orissa i.e. Paradeep which holds its recognition as the deepest natural port in the whole of India. The main drainage system of this area is represented by several rivers at their old stages flowing sluggishly towards the sea, which form topographic features like peneplains, natural levees, deltas, etc. (Fig.1). The major rivers flowing in the coastal belts are the Subarnarekha, the Budhabalanga, the Baitarani, the Brahmani, the Mahanadi and the Rushikulya. This region is the combination of several deltas of varied sizes and shapes formed by these rivers. The coastal belt has an area of 40,166 sq. km with a population of 68,79,379, which is 45 percent of the population of 9 coastal districts of Orissa.
