Introduction

Soil is considered one of the world’s limited, non-renewable resources. Under cropland conditions, it takes between 200 and 1000 years for 2.5cm of topsoil to form (Piementel et al., 1995). The continued maintenance of fertile soil is essential in order to meet basic human needs. It strengthens the provision of ecosystem services such as food production and climate regulation, and provides the basis of livelihoods for millions of people across the world (Ma, 2005). The multi-functionality of soils is key to the sustainable use of land and soils. A healthy soil performs six essential functions (Andrews et al., 2004) namely: i) Physical Stability and Support, ii) Water Relations, iii) Resistance and resilience- iv) Nutrient Cycling, v) Biodiversity and Habitat and vi) Filtering and Buffering. These soil functions are controlled by various soil properties. Among them soil structure is one of the most important properties of soil, which describes soil condition and has a great influence on crop production.

The arid and semi-arid regions of India are drought prone and the availability vegetation of these regions is more acute during summer when the quality of the pastures becomes vulnerable. Small ruminants in the semi-arid regions need to adopt special physiological function to maintain thermal equilibrium. The reproductive efficiency of different breeds of sheep inhabiting in the semi-arid regions of India is relatively low (Arora and Garg, 1998).The nature of nutritional resources and management problems differs with climate, soil and vegetation, the physical process which governs the animals reproductive performance are the same; the female must reach puberty, show behavioral estrus and shed one or more ova which have then to be fertilized. Dietary nutrition promotes the programming and expression of the metabolic pathways that enable animals to achieve their genetic potential for reproduction. Nutrition has an important impact on the reproductive performance in sheep, but the magnitude of the effect on reproduction may vary with the season (White et al., 1983). Sheep are more prone to neglect compared to cattle and often suffer from lack of feed and fodder. The animals during the grazing are exposed to combined stress (Sejian et al., 2010 ab, and 2011) .This leads to decrease in body weight and loss of reproductive functions. Concurrently, Rhind and Mc Neilly (1986) showed that ewes with low body fat reserves had fewer large ovarian follicles and therefore the potential for subsequent maturation and ovulation declined. 

Introduction  

Developing effective strategies for improving and stabilizing rainfed crop production continues to be a prime concern in the semi-arid region of western India. Rain water management is most crucial aspect in rainfed production systems. Growing uncertainties associated with rainfall pattern (Ali et al., 2007) add to the complexity of the challenge. The medium deep black soil region of Rajasthan is spread predominantly in Jhalawar, Kota, Baran, Bundi, and Sawai Madhopur districts of South-eastern Rajasthan (Fig. 1). This region is characterized by almost flat alluvial plains interspersed with hills of Arawali and Vindhyan ranges and rock outcrops. 

Increasing evidence over the past few decades indicate that significant changes in climate are taking place worldwide as a result of enhanced human activities. The inventions that were discovered during last few centuries, more so in the last century has altered the concentration of atmospheric constituents that lead to global warming. The major cause to climate change has been ascribed to the increased levels of greenhouse gases like carbon dioxide (CO₂), methane (CH₄), nitrous oxides (NO₂), chlorofluorocarbons (CFCs) beyond their natural levels due to the uncontrolled activities such as burning of fossil fuels, increased use of refrigerants, and enhanced agricultural related practices. The temperature increase is widespread over the globe and is greater at higher northern latitudes. Land regions have warmed faster than the oceans. January 2000 to December 2009 was the warmest decade on recordreported by NASA. These activities accelerated the processes of climate change and increased the average global temperatures by about 0.8°C (1.5°F) since 1880 (NASA,2010). Global average sea level has risen since 1961 at an average rate of 1.8 [1.3 to 2.3] mm/yr and since 1993 at 3.1 [2.4 to 3.8] mm/yr, with contributions from thermal expansion, melting glaciers and ice caps, and the polar ice sheets. Satellite data since 1978 show that annual average Arctic sea ice extent has shrunk by 2.7 % [2.1 to 3.3%] per decade, with larger decreases in summer of 7.4% [5.0 to 9.8%] per decade. Mountain glaciers and snow cover on average have declined in both hemispheres. It has also induced increased climatic variability and occurrence of extreme weather events in many parts of the world.

Wheat (T. aestivum) is a staple food of the vast majority of the human population in most part of the world; Europe, West Asia, South East Asia, Americas and North Africa. It provides more nourishment than any other food crop and leads all other food crops-rice, maize and potato on a global basis. The wide varieties of food products prepared from it make the crop popular and also a reason for its expansion even to non-traditional wheat cultivated areas. As a leading cereal crop, it is cultivated widely under varied agro-ecological regions and cropping systems throughout the world. It is one of the first plants domesticated and cultivated by humans, which played a critical role in the transition from hunter–gatherer groups to stabilized societies with an agrarian foundation. Wheat is harvested every month of the year somewhere in the world, from as far south as Argentina and as far north as Finland, and it is grown over a substantial area in almost every country of North and South America, Europe, and Asia (Fig. 32.1). Even though, the normal planting period of wheat falls in the same month across different countries, the harvesting period is different (Fig. 32.2).

Yak (Poephagus grunniens)is the most remarkable and multipurpose domestic animal living at high altitudes of the Himalayas. Features common to the environment in which yak live are extreme cold, mountainous terrain, high altitudes with reduced oxygen in the air, high solar radiation and short growing seasons for herbageanda variable assortment of herbage, sparse insome areas. Generally, the yak habitat ranges from 3000-6000 m abovemean sea level (msl), where the alpine pastures are found and there is no absolutely frost-free period during any part of the year. Wilted herbage provides some sustenance for the yak at other times of year, but not insufficient quantity for their requirements (Fig. 9.1). Many of thecharacteristics of the yak can be regarded as adaptations to these conditions, in which cattle of other species have difficulty in surviving (Wiener et al., 2003).The yaks are considered as the life line of the highlanders in remote terrain because yak is the only sustainable livelihood due to non-availability of arable land for major agriculture. Yak husbandry is one of the important and indispensable aspects of the Indianstates, namely, Arunachal Pradesh, Himachal Pradesh, Jammu and Kashmir, Sikkim and Garhwal hills of Uttarakhand where other livestock species can hardly live but yaks can survive, reproduce and produce milk, meat, wool and other by-products.

Abstract

The development of nano technology creates an excellent opportunity to address complex technical  issues of food supply chain. Failure to embrace nano technology will deny the horticultural sector an opportunity to capitalize on improved product visibility, food safety, quality and security and associated economic benefits. Agricultural and food supply chain management is complex due to the diverse characteristics of agricultural products. There are numerous types of horticultural crops and products, many of which are perishable. In addition, the degree of standardization of some kinds of fruit products and their management is still low. In this regard, the potential application of nano technology to the horticulture is reviewed. Investigation confirms that incremental applicationof nano technology in the horticulture,

Introduction

Insects have a long history through many geological periods. They appeared in the world long before man. Over 750,000 species of true insects have already been described, for centuries man has fought insects as pests, carriers of disease and destroyers of his food. This combat will continue, for humans have never eradicated a single species. Insects such as flies, fleas, lice and mosquitoes directly attack man and domesticated animals. Others attack indirectly by transmitting dangerous diseases to man and animals.

Agricultural production in India is still vulnerable to vagaries of monsoon rainfall in spite of rapid technological advancements like 1) Availability of high yielding varieties 2) Improved crop management practices and increased irrigation availability and effective control of pests and diseases and etc, over last few decades. Majority of Indian farming community which broadly comprising of small and medium farmers are often subject to climate extremes such as droughts, floods, heavy rainfall events, heat and cold waves, frost, hail storms during the crop growing season. The probabilities of occurrence of such climate extremes and associated crop damages and production losses are common in tropical countries like India. Compensation to the resource crunched farmers in the form of crop insurance seems to be the best option for speedy recovery from the losses incurred during the season. It provides security and stability to farm income by protecting the farmers’ investment in crop production and then improves their risk bearing capacities. Crop insurance scheme is based on the fundamental principle of insurance business in which risk is distributed across space and time. For successful implementation of any crop insurance scheme operating presently in the country, proper monitoring of accurate weather parameters at the identified locations throughout the crop life cycle is important.

Veterinarians will be often required to mention the specific animal husbandry terms for various purposes like writing certificates for various schemes, postmortem, attending court of law in veterolegal cases etc. Hence this chapter aims in refreshing the vets with the common terms associated with different domestic animals and animal husbandry activities. 

Introduction

Almost all agricultural commodities include cereals which are stored in go-downs or store on large scale or small scale because storage of food grains is inevitable both in times of deficit and surplus production (Lal, 1985). The intensification of food production has led to several problems in the post-harvest phase including the major concern of pest infestation during storage. The post harvest losses in India have been estimated to be 12 to 16 million metric tonnes of food grains every year (Singh, 2010). The stored grain pests are serious pests of dried, stored, durable agricultural commodities and of many value-added food products and non-food derivatives of agricultural products worldwide.

ABSTRACT
The ‘steel-drum type’ biogas plant installation programme in Punjab was initiated in the early seventies, whose construction works were entrusted on the Department of Agriculture. Because of their high cost and high failure rates then, only the affluent farmers could afford to install. In the meantime, a cheaper Chinese model, also known as Janta type (dome-type replacing the drum-type) plant, became popular but was still out of the reach of ordinary farmers. With dual objectives of cost reduction and efficient biogas production to make it affordable to small farmers, a coordinated research was initiated. Detailed extension surveys were carried out in Ludhiana district which inferred that the farmers did not install the gas-holding steel drum though they purchased it. A significantly low cost Katcha-Pucca plant model of 15m3/d capacity was developed and installed in Sangrur district. Similar digester was tried for Janta model in which the inlet, outlet and dome (gas holder) were masonry works but the digester was a Katcha pit, the dome of the plant being modified to a semi-circular dome. More than 80 such plants are functional in a single village, and more than 40–50% of the plants installed in Punjab and Haryana are these PAU designs. The chapter deals in greater details on the design aspects and the extensive field works carried out to achieve these successes, along with some relevant facts and figures. The write-up is written as a commentary, rather than a typical chapter, for the benefit and interest to the readers.

Introduction

Tree growing in hot arid region is basically concerned with the management of trees for conservation and for limited production objectives like wood for fuel, poles and fencing material; leaves for livestock fodder; and pod/seeds for many types use in human diet. The role of trees to conserve the fragile ecosystems of hot arid regions has been well recognized (Mann and Muthana 1984). The trees also provided so many services to mankind, which make them an intricate part of man-livestock-agriculture continuum, the lifeline of hot arid regions (Saxena 1997). 

Drug designing is the approach of finding drugs by design based on their biological targets. The substance used for medical purpose, either alone or in mixture that changes the state or function of cells, organs or organism as a whole is known as a drug. So typically a drug target is a key molecule involved in particular metabolic or signaling pathway that is specific to disease condition or pathology, or to the infectivity or survival of a microbial pathogen. Drugs may be designed that bind to the active region and inhibit the key molecule that causes disease. However these drugs would also have to be designed in such a way that they should not affect any other important molecules similar to the key molecule. These can also be used to enhance the normal pathway of metabolism by promoting specific molecules that may have been suppressed in disease state.

Neisseria meningitidis, also simply known as meningococcus, is a gram-negative bacterium best known for its role in meningitis. It only infects humans; there is no animal reservoir. It is the only form of bacterial meningitis known to cause epidemics. The carbohydrate capsule of N. meningitidis determines its virulence and is targeted by the immune system. Approximately 12 strains of N. meningitidis exist and are characterized by the polysaccharide expressed on its capsule: A, B, C, 29-E, H, I, K, L, W-135, X, Y and Z. Inhibition of Pencillin Binding proteins (PBPs) leads to irregularities in cell wall structure such as elongation, lesions, loss of selective permeability and eventual cell death and lysis. 3-D structure of PBP was studied using Bioinformatics tool. Using Homology modelling, converted protein sequence of penicillin binding protein, extracted from NCBI server, in FASTA format and performed PDB-BLAST to search a desired template. Selection of template was based on lower E-value, bit score and identity. Using MSA with the help of CLUSTAL W software conserved region was found between the target and template sequence, 1K25. The 3-D structure of penicillin binding protein was found with the help of Modeller 9v2 and molecular dynamics was performed using GROMACS software. The docking was performed (Autodock 3.0 software) using 3 ligands viz. Cefuroxime, Chloramphenicol, Cefalotoxime with standard Bioinformatics tools.

The first step of sexual reproduction (Flowering) is of paramount importance in agriculture, horticulture and plant breeding. The change from the vegetative state to the reproductive state is one of the most dramatic events. Flowering leads to an exciting succession of events like anthesis, fruit set, fruit development, maturation and ripening. It provides for the propagation of the species and assists in crop improvement through genetic recombination. Plant growth regulators have remained an important component in horticulture, agriculture from time immemorial, because they were effective means of quantitative as well as qualititative improvement in growth and development of crops. Plant growth and development as well as the responses to environmental factors, are highly regulated by complex and coordinated action of the endogenous hormones (Reddy and Bhagwan, 2014).

ABSTRACT
The global energy demand is increasing day by day. Now-a-days, the supply of global energy is highly dependent on fossil fuels (viz., crude oil, lignite, hard coal, natural gas). But, on one hand the source of fossil fuel is decreasing at a rapid rate, and on the other hand the burning of fossil fuel is also degrading the environment due to huge Greenhouse Gas (GHG) emission (FAO/CMS, 2011). Hence, there is an urgent need of an alternate clean energy source that can sustain the future development undeterred while still protecting the environment. Biomass is considered as a sustainable source of clean energy that is useful in steam, fuel and chemicals production. It can be digested in controlled environment to produce biogas. The biogas is a clean, non-polluting and smoke-free fuel (Weiland, 2010) which can be used for applications that include cooking, space cooling/refrigeration, heating, electricity generation and gaseous fuel (CNG) for vehicles (Weiland, 2003). This paper analyses possible alternatives to process and utilise biogas for energy at industrial scale as a petroleum fuels replacement.

Buffalo plays an important role in Indian livestock economics.  India has more than the half of the world buffalo population, contributing 50% of total milk production of the country.  The buffalo is said more productive than an average cow due to the higher fat percentage (7%) in the milk, better feed conversion ability and disease resistance.  Buffaloes have lower reproductive efficiency in the form of delayed age of maturity, longer calving interval, weak / silent estrus, seasonality of breeding, poor libido and poor semen quality. A large number of buffaloes do not conceive due to some gynaecological problems and are being slaughtered every year.  The most commonly observed reproductive disorders are detailed below.

Abstract
 
The field experiment was conducted during rabi season at the Baruipur Research Farm of the Calcutta University using treatments as T1-NPK 100%, T2- Compost 100%, T3- Compost 50%+NPK 50%, T4-Vermicompost. 100%, T5- Vermicompost 50%+NPK 50%, T6-FYM 100%, T7-FYM 50%+NPK 50%, in a Randomised Block Design (RBD) replicated thrice.  The results show that the amount of available N content in soil  has been found to be increased with the progress of crop growth upto 45 days of crop growth and thereafter, the amount of the same decreased with the crop growth irrespective of treatments. The amount of P content in soil has been found to be increased with different treatments, being maintained highest amount (18.30 kg/ha) in the treatment Vermicompost 50%+ NPK50% followed by the treatment where 100% NPK and 100 % vermicompost were applied. The results show that the amount of K content in soil was increased initially and thereafter, the amount of the same decreased with the progress of crop growth.

Abstract

Chhotanagpur plateau is well-known for its quality vegetable production, however, indiscriminate uses of chemical fertilizers and pesticides in different vegetables lead to more yields but of their inferior quality of produces. The over uses of agro-chemicals also drastically affect the soil bio-physico-chemical properties. In this context, an alternative approach was taken into account through present study in order to address such problems. For the purpose, cabbage cv. Golden Acre was grown in organic experimental plots of the university by using ‘Sasyagavya liquid organic formulation’ to observe its effects over the crop and soil bio-chemical properties of the experimental site.Theexperiment was designed after CRBDby adoptingseven treatments i.e.T1: 1% Sasyagavya; T2: 5% Sasyagavya; T3: 10% Sasyagavya; T4: 15% Sasyagavya; T5: 20% Sasyagavya; T6: 25% Sasyagavya and T7: Absolute Control withtheir three replications. Different growth, yield and quality attributes of the crop and soil bio-chemical properties of the experimental soils were studied. 

The focus of world’s trade and economic activities is increasingly being shifted from resource-based economics to knowledge-based economics. This paradigm shift has been triggered due to the implementation of Convention on Biodiversity (CBD) and other related international treaties and policy frameworks. CBD for the first time states that bio-resources are the sovereign property of the countries in which they are found. It further stipulates that access to bio-resources by outside parties can be made only after prior approved consent of the concerned stakeholders and also with mutually agreed terms and conditions for equitable sharing of benefits accrued from the commercialization of biodiversity. To realize such proclaimed rights given in CBD and to fulfill obligations of various other relevant treaties, particularly in the context WTO regulation, it is imperative that the bio-resources-rich nations like India have comprehensive knowledgebase of the biodiversity and associated information systems in accessible form.

Vegetables constitute a substantial part of human diet supplying vitamins and minerals, in which other food materials are deficient. India has emerged out as the second largest producer of vegetables in the world. More than 25% of fruits and vegetables are damaged by the attack of insect-pests (Pradhan, 1964).Vegetable crop is damaged by both sucking as well as chewing insect-pests. Sucking pests are aphids, whitefly, jassids and bugs attacking in initial stage whereas chewing pests like borers, infesting in flowering and fruiting stage. Sucking pests may transmit the viral diseases which cause severe loss in yield in tomato and okra crops. About 13-14 % of total pesticides used in the country are applied on vegetables. Average pesticide consumption in vegetables in India around 0.678 a.i. kg/ha. Maximum pesticide usage in chilli followed by brinjal, cole crops and okra. Global agro-chemical consumption dominated by fruits and vegetables, accounting 25 % of total pesticide market. Major insect-pests of different vegetable crops and their management are as follows:
 
Cole crops

Cabbage (Brassica oleracea var capitata) and Cauliflower (Brassica olercea var botrytis L) are grown in cold and moist climate. It is rich in minerals namely iron, magnesium, phosphorous and sodium. Cole crops were attacked by number of insect pests and cause heavy economic loss. The major insect pests are described below along with their management:

Okra Abelmoschus esculentus L.

Cotton Jassid Amrasca biguttula Ishida (Hemiptera: Cicadellidae)

Economic importance: Sucking pest cause damage during May to September. Adults are also found on plants such as potato, brinjal, tomato, etc.

Mark of identification and life cycle: Adults are about 3 mm long and greenish yellow during the summer, acquiring a reddish tinge in the winter. The winged adults jump or fly away at the slightest disturbance and are also attracted to light at night. Females lay about 15-38 yellowish eggs on the underside of the leaves, embedding them into the leaf veins. The eggs hatch in 4-5 days. Nymphs are wedge-shaped and are very active and complete five instars with 3-5 days in each instars. Adult live for 11days.

Nature of damage: Damage to the crop is caused by the adults as well as by the nymphs, both of which are very agile and move briskly, forward and sideways. They suck cell-sap from the underside of the leaves and pass through six stages of growth in 7-21 days. They feed constantly on the plant juice. The pest completes seven generations in a year. Damage symptoms: Injury to plants is due to the loss of sap and probably also due to the injection of toxins. The attacked leaves turn pale and then rust-red. With change in appearance, the leaves also turn downwards, dry up and fall to the ground.

Solanaceous Vegetables

Solanaceous vegetables are also infested heavily by several major insect pests.

Brinjal Solanum melongena L.
 
Fruit and shoot borer Leucinodes orbonalis Gunnee (Lepidoptera: Pyraustidae)

Economic importance: Most destructive pest of brinjal, found throughout the country. Besides brinjal, the pest is also known to infest potato, bitter gourd, pea pods, cucurbits and other solanaceous etc. The infestation on brinjal can be as high as 70 per cent. The pest is active throughout the year, except in severe cold weather in North India.
 
Mark of identification and life cycle: Moths wings are white with pinkish or black tings and are ringed with small hair along the apical and anal margins. The fore wings are ornamented with a number of black, pale and light brown spots. Female lays 80-120 creamy white eggs, singly or in batches of 2-4 on the underside of leaves, on green stems, flower buds or the calyces of fruits. Caterpillars are creamy when young, but light pink when full-grown in 9-28 days. Pupate in tough silken cocoons among the fallen leaves with period of 6-17days and adult survive for 2-5days of its life cycle. A single life-cycle takes 22 - 25 days extending up to 74 days during winter and there may be 8 - 12 generations in a year.

Introduction

Agricultural insect pests routinely disturb crop production, yet their effects are relatively minor compared to the economic disruption, Suffering, and death caused by medical pests. So, the medical pests compose an extraordinarily important group of insect pests. Insect pests of public health importance had a remarkable impact on human history and this influence still continues (Higley et al., 1989). Diseases carried by insect are prevalent in many parts of the world, particularly the tropical and subtropical countries. These organisms have the capacity to inflict injury, disease, discomfort, or distress. They may cause direct illness and suffering through stings and bites, infested wounds, or allergic reactions. They may feed on blood or body tissues and thus may also transmit deadly pathogens or parasites. Economic losses associated with these pests are borne not only by the affected individuals and their families, but also by human society in general (Higley et al., 1989).

The oilseeds crop occupies an important position in agriculture economy in the world. Indian agriculture has made considerable progress, particularly in respect of food crops such as wheat and rice in irrigated areas; however, performance has not been so good in case of other crops particularly oilseeds, pulses, and coarse cereals. Therefore, after achieving self sufficiency in food grains the government is focusing attention on these agricultural commodities. On the oilseeds map of the world, India occupies a prominent position, both in regard to acreage and production. India is the 4th largest edible oil economy in the world and contributes about 10 percent of the world oilseeds production, 6-7% of the global production of vegetable oil, and nearly 7 percent of protein meal. This sector also has an important place in the Indian agricultural sector covering an area of about 26.5 million hectares, with total production of over 25.3 million tonnes in the triennium ending 2015-16 (GOI, 2016). This constitutes about 14.8 per cent of the gross cropped area in the country. A wide range of oilseed crops is produced in different agro-climatic regions of the country. Insects-pests are one of the limiting factors in the production of oilseed crops. Management of these pest problems by using possible control techniques could increase the quality and quantity of the products. These crops are damaged by a more number of insect pests, of which some are more serious. These pests can be effectively controlled by the integration of different techniques such as use of various safe insecticides/biopesticides, some modification in cultural practices and use of pest tolerant varieties. Integrated pest management approaches will help to increase the production and productivity of oilseed crops by reducing the pest damage without any adverse effect on the agro- system and erosion in the environment. 

Pest wise information of oilseed crop and management of major pests are described below.

Pollination is the transfer of pollen from the male part of the plant to the female part of the plant of the same species. The anthers, the male part of the flower, produce pollen. The pollen must be transferred to the upper female part of the flower, the stigma. Here the pollen germinates and grows down the style (the elongated portion of a pistil that connects the ovary with the stigma of a plant) to where fertilization occurs and the seeds develop in the ovaries. A fruit is a ripened ovary.

Introduction
 
The relationship between insects and animals is complex. Insects are injurious to animals in myriad ways, whereas a few are beneficial. Some carry deadly disease germs and transfer them mechanically; others serve as necessary hosts of disease germs. Insects injure livestock by several ways like biting, crawling and scratching. Some burrow in the tissues, which become inflamed or are actually destroyed. Many insects are more or less specific to a host while others attack all kinds. Cattle tick, for example, attacks cattle, horses, mules, and sometimes sheep, but it is only to bovines that it transmits cattle tick fever. It is almost impossible to group insects in a list having the same characteristics, habits and methods of injuring livestock. The losses are found due to infection or infestation of ectoparasites on animals. The ectoparasites sucks blood which causes development of anaemia.They irritate the skin of the animals creating itching resultantly loss of hairs/ wools occur. Irritation may also leads to restless that adversely affect the appetite and water intake. Some ticks are responsible to transmit dreadful disease like Red water, Theileriosis, Anaplasmosis etc. Fleas act as intermediate host for some worms eg. Diphylidium caninum.They causes skin diseases like mange, Flea bite dermatitis, and cutaneous myiasis. Loss of body weight in all animals, drop in milk production in milch animals, decrease in meat production, retarded growth of young animals can transmit bacterial, viral, protozoal and rickettsial diseases. They decrease immune response to diseases. They causes annoyance and wry to the animals. The insect bites and blood sucking flies causes direct injury to the animals.

Introduction

With the change in global scenario there is increase in pressure of meeting the food requirements of rapid growing population but due to scarcity of resources it is becoming very difficult to meet the needs of present population but even if there is so much problem still nature has provided solution to sort out from it through hybrid seed production through male sterility. As male sterility is a condition in which pollen grain is either absent or non-functional in the pollen grain. Its first case was reported by Koelreuter in 1763. Later many scientist have reported about its role in hybrid seed production. Mainly the male sterility is characterized by malformation of androecium, lack of normal anther sac, inability of pollen to mature or to release from the anther sac and inability to develop normal microspore or pollen. Due to such malformation male sterility is characterized into phenotypic male sterility, genotypic male sterility and chemically induced male sterility. Later in 1998, Kaul further generalised the phenotypic male sterility into structural, sporogenous and functional male sterility. In case of structural male sterility stamens are completely absent or if present then it is either malformed or modified into other floral part. While in case of sporogenous male sterility a case of abnormal microsporogenesis has been reported. In functional male sterility pollen development is normal but its function is impaired.Genotypic male sterility which is further classified into genetic, cytoplasmic and cytoplasmic genetic male sterility.

Abstract: Agro-ecosystem analysis of the island farming system revealed four distinct micro farming situations (MFS) viz., Hilly (MFS I), Slopping hilly upland (MFS II), Medium upland valley (MFS III) and Low lying valley (MFS IV). The enterprise combination study indicated the suitability of plantation based cropping sequences + backyard poultry and livestock in hilly areas, Short and medium duration paddy, vegetables, floriculture, plantations, fodder + backyard poultry + goat,  fish cum poultry cum duck and cattle in slopping hilly uplands, vegetables, plantations + backyard poultry, fish cum poultry cum duck in medium upland valley and long and short duration paddy, vegetables + backyard poultry, fish cum poultry and cattle in low lying valley micro farming situations.

Introduction

Pests and diseases are very serious issues in vegetable crops and account for nearly 25-30% damage to the expected yields across different crops inspite of high amount of chemical use. Excessive reliance on chemicals has created problems of pest resistance to pesticides, decimated useful fauna and flora as well as imperilled the delicate ecological balance. In addition, pesticide treadmill lures the farmers for ever increasing use of pesticide dosages, thereby encouraging a vicious cycle of environmental pollution. Vegetable crops are one of the major groups of crops that contribute heavily in this regard, being the third major consumers of pesticides after cotton and rice in our country. Insect pests and diseases inflict the horticultural crops especially vegetable crops more than others because of their supple nature, intensive cultivation under high moisture and input regimes, short duration and denser canopy of the crops.

Abstract

Water is an indispensable natural resource for sustaining the environment, supporting life and responsible for sustainable agricultural growth and development wherein agricultural sector is the major user of the water resource. The integrated management of water resources could only be possible through adoption of efficient and optimum use of irrigation water, which could only be ensured by judicious and economic use of irrigation potential whatsoever created to increase crop production. The integrated water resources management also includes the concept of rainwater management that has got an immense important on the way to develop the rainfed farming system. Previously, rainfed agriculture was associated primarily with conservational land treatments to check soil erosion and land degradation. But in the areas of medium to heavy rainfall, there is ample scope of tapping excess rain water through suitable water harvesting structures constructed for this purpose for its subsequent uses as irrigation or to apply lifesaving irrigation to the crops which should also come under the purview of water management for crop production.

18.1. INTRODUCTION

Plant genetic resources (PGRs) are the foundation for the development of a food and nutritionally secured society. Food is the foremost important to sustain life and livelihood followed by shelter and cloth. Thus, the slogan of 3Fs may be modified as, “Food, Frame (shelter) and Fibre (cloth)”. All these 3Fs we can get from PGRs. There must be balance between demands and resources. Gradually the demand for basic needs increasing. So, we have to improve the PGRs to cope with the increasing demands. PGRs are the foundation for the development of these 3Fs. India is a country rich in crop biodiversity and genetic resources. The status of Germplasm accessions in the National Gene Bank is being presented in Table 18.1.

Introduction

The Indian lac insect, Kerria lacca (Kerr) (family Tachardiidae (Kerriidae), super family Coccoidea of the order Hemiptera) is widely cultivated in India for their products viz., resin, dye and wax.Lac products have diverse uses in food, pharmaceuticals, surface coating, electrical, cosmetic industries, etc. Lac cultivation is one of the major sources of income for the tribal community of the country. India is the global leader in lac production. Out of 2 strains (kusmi and rangeeni) available in lac insects, Kusmi lac insects are specific to India and contribute good quality and quantity lac. Although lac insects can survive on more than 400 host plants, important host plants of lac insects are Butea monosperma (Palas), Schleichera oleosa (Kusum), Ziziphus mauritania (Ber) and Flemingia semialata in India.

Bananas and plantains constitute the fourth most important global food commodity (after rice, wheat and maize). They are cultivated in over 120 countries in the tropical and subtropical regions of the world in an area of  approximately 100 million hectares, where they constitute a major staple food crop for millions of people, as well as providing a valued source of income through local and international trade.
 
Banana is one of the oldest fruit crops of India, finding its reference even in epics like Ramayana. India is  believed to be one of centres of  origin, besides southeast Asian countries like Burma, Thailand, Malaysia and Indonesia. It is a crop having multifarious uses as every part of the plant is utilized and hence aptly  called as ‘Kalpatharu’ the plant of virtues. It is important internationally from the point of view of  trade as well as livelihood security.

Climate Change has emerged as one of the most serious environmental concerns of recent times. The most imminent climatic change is increase in atmospheric temperature due to increased levels of greenhouse gases such as carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O) and hydrochlorofluoro carbons (HCFCs). Because of increasing concentrations of the greenhouse gases in atmosphere, there is much concern about future changes in the climate system viz., Atmosphere, Lithosphere, Biosphere, Hydrosphere and Cryosphere. Direct or indirect effects on the society linked sectors like water, forestry, agriculture, animal agriculture, fisheries, land and marine biodiversity and health due to climate change/variability are many-fold and economic impact of climate change is enormous. The recurrent drought and desertification threaten seriously the livelihood of over 1.2 billion people who depend on land for most of their needs.

The aim of this book is to further strengthen the knowledge of readers on management of disasters so that they are better prepared to cope with more frequently occurring natural and manmade disasters.

The process that helps us to face disasters effectively is commonly known as disaster preparedness.  When a disaster strikes, it affects us directly and immediately. While as the government, international agencies such as United Nations, Red Cross Society, non government organizations, like Ramakrishna Mission, OXFAM, CARE, resident welfare associations in urban areas and panchayats in rural areas assist us when faced with disasters the community, invariably remains the first responders. Hence, the individuals as a part of community should prepare adequately to prevent, face and respond to disasters effectively. History has  shown that where communities have prepared adequately to confront disasters, losses to life and property have been less and environment could be protected. People living in an area may be prone to more than one type of disaster. For example Kutch District of Gujarat is vulnerable to floods, drought, cyclones and to earthquakes. Such an area is called ‘multiple hazard’ zone.

Basic thought of Sampling

The data is very important in every field for decision making whether it is medical sciences, engineering sciences, agricultural sciences and management sciences etc. for this we need to plan the correct data. If we don’t have correct data then based on that we cannot plan good decisions and it will provide misleading results. So, to achieve or plan the right data it is necessary to have the right technique which is to be used while collecting data and an appropriate method of data collection is preferred. From this, the two important questions arise (i) what are those methods required to obtain paramount data or sample and (ii) how best to use the data or sample to estimate the characteristic of the whole population i.e., what are those methods by which we can study our population parameters to draw a proper statistical inference.

The forest cover in most tropical countries has been under severe pressure and is diminishing at an alarming speed; consequently, they are experiencing severe biodiversity losses, reverting to a mature state at a slower rate with low resiliency. These tropical countries are aware of the danger causing due to the loss of forests, and large afforestation programmes have been launched by forest departments, private companies, and donor-supported projects. Nevertheless, plantation activities have rarely been able to keep pace with the deforestation rate, not to mention replacing what has been lost during the past. Plantation programme through afforestation activity is not only the matter of the forest department alone but also the combined responsibility of all the foresters. The appeal of forest planting has changed over the years following the broader demand spectrum.

To some extent, the forest plantations fail to create the diversity of plants and wildlife that has been lost. Hitherto, large-scale plantations are still necessary both directly to cater to the needs of industrial wood and help to minimize the pressure on the remaining natural forests. During the past decades, many government programmes have emphasized using
