One of biggest challenges facing animal science is to increase the production in the context of climate change. Animal performance may be limited by adverse climatic focus (Sejian et al., 2010; Sejian et al., 2012). The economic impact of climate changes in relation to livestock production are widely reported, and several losses are predicted if current management systems are not modified to reflect the shift in climate. Climate change poses formidable challenge to the development of livestock sector in India (Sejian et al., 2013; Naqvi et al., 2013). Global warming could increase water, shelter and energy requirement of livestock for meeting projected milk demands. The anticipated rise in temperature between 2.3 and 4.8°C over the entire country together with increased precipitation resulting from climate change is likely to aggravate the heat stress in dairy animals, adversely affecting their productive and reproductive performance, and hence reducing the total area where high yielding dairy cattle can be economically reared. A preliminary estimate indicates that global warming is likely to lead to a loss of 1.6 million tonnes in milk production in India by 2020.

Seasonal variations in climatic conditions impact the availability of feed in the livestock (Sejian et al., 2014; Bagath et al., 2016). Over and above the effect of seasonal variations that cause considerable economic hardship, it is the unforeseen and unexpected periods of inclement and severe weather conditions which exacerbate the gross economic losses in livestock industry (Sejian and Srivastava, 2010; Sejian et al., 2010). In addition to mortalities of livestock associated with severe climatic conditions, reductions in reproductive and productive performances generate sizeable economic setback. Impressive advances in research have been made to assess the impact of climatic stressors on the physiological and dynamic responses of livestock (Shaji et al., 2015; Maurya et al., 2015). At the same time livestock managers and farmers continue to search for management options which can alleviate and reduce the effects of severe weather on livestock performance and productivity. This chapter will address in detail the impact of environmental stresses on livestock production and reproduction. These attempts will help the scientific fraternity to develop appropriate mitigation strategies to improve ruminant livestock production in these agro-ecological zones. This might pave way to improve the livelihood securities of poor and marginal farmers of this tropical environment via an appropriate universal research agenda.

5.1 Introduction

A farm pond that collects and harvests in-situ rainfall as well as runoff from the catchment area can be used for many purposes: the most important of which is the supply of water to crops as supplemental irrigation. It is no doubt a viable source for integrated farming system. In addition, the water of the pond can be used for domestic and to some extent for the industrial uses. It is also a good source for recreational use. Total water demand of the pond including irrigation to different crops in different seasons, domestic and other non agricultural uses are to be assessed. While estimating the crop water requirement and irrigation requirement, various crops to be grown in the service area of the pond, their water requirements, crop duration, extent of coverage and water management practices followed are to be taken into consideration. Multiplying the irrigation requirement with crop coverage area, volumetric irrigation water requirement of crop can be found out. Summation of irrigation requirement of all crops grown in service area of the pond, gives total irrigation demand of the pond.

Farm ponds are normally used for irrigation to crops as well as to meet the live stock water demand. Normally the large live stocks like horse, cattle require 20 thousand litres of water per head per year whereas the small live stocks like sheep, goat, pigs require 2 thousand litres of water per head per year. Adding the irrigation demand to the livestock demand, total water requirement of the pond is calculated. In addition to this, if the pond water is used for industrial, domestic and other sectoral purposes, then water used in all such sectors are to be added to irrigation and livestock demand to estimate the total water demand of the pond.

Irrigation Methods

Pressurized irrigation

12.1 Surface Irrigation

Surface irrigation method refers to the manner or plan of water application by gravity flow to the cultivated land wetting either the entire field (uncontrolled flooding) or part of the field (furrows, basins, border strips). Most irrigated areas have characteristic land features and differ from those in other areas. Hence, for efficient application of water it is important to select such method of irrigation, which fits one’s own land.

The adoption of a certain method need not be necessarily based on convention or that followed in the adjoining farm. The factors, which determine the suitable method of irrigation are local conditions (soil type - its permeability & water storage capacity; land topography, climate, water availability & water quality), crop type, type of technology, previous experience with irrigation, required labour inputs etc. Good yield of crops can be obtained from irrigated land only if the water is applied judiciously to meet the needs of the plant, but not to cause waste and damage. Irrigation water is applied to cultivated land by the following surface methods of irrigation:

Microbiology is a branch of science dealing with the study of organisms which are too small to be seen clearly by unaided eye. Roughly the organisms with a diameter of 0.1mm or less, which can not be seen by the human eyes unaided, come under the domain of microorganisms.

Thus, the laboratory work dealing with the microorganisms needs special care to avoid infection and infusion for maintaining good health. In fact all microorganisms should be treated as potential pathogens. Thus, for working with microorganisms aseptic techniques must be followed by students as well as by the laboratory assistants and teachers.

Introduction

The sustainable agriculture begins with ideal soil health with minerals and organic matters. The sustainable farming practices enhance and protect soil health, water quality and water quantity, biodiversity, manage insect pests, disease and weeds. The Indian council of Agricultural Research (ICAR) set up an All India Soil Survey Committee in 1953 which divided the Indian soils into eight major groups. (i) Alluvial soils (ii) Black (or Regur soil) (iii) Red and Yellow soils (iv) Laterite soils (v) Arid and desert soils (vi) Saline and alkaline soils (vii) Peaty and marshy soils and (viii) Forest and mountain soils.

Introduction

On the basis of inputs based ecological principles, the all possible and available resources are allocated to achieve maximum outputs. One of the most promising paradigms of external inputs based agriculture that have emerged for the benefit of small scale resource-poor farmers and that is termed as low external input and sustainable agriculture (LEISA), which can enable such farmers to achieve higher income and attain sustainability by: (i) Optimizing the use of locally available resources, thereby achieving a synergetic effect amongst the various components of the farming system (soil, water, animals, plants, etc.) so that they complement each other in the production of output; and (ii) Minimizing the use of external inputs, except where there is a serious deficiency and where the effect on the system will be to increase recycling of nutrients.

Low External Inputs and Sustainable Agriculture (LEISA): Low external input sustainable agriculture (LEISA) is a way of thinking about farming. It incorporates some ideas found in what people have labelled eco-logical, organic, regenerative, biological, or simply alternative agriculture. Amongst the goals that now drive the interest in low-input sustainable agriculture, two stand out: profitable and productive farming, and protection of resources and environmental quality. Companion objectives include ensuring safe and nutritious food supplies and reducing health risks to farm workers. LEISA involves farmers substituting management, scientific information, and on-farm resources for some of the purchased inputs they currently depend on maintain production sustainability. Sustainability has been defined, for the purpose of including resource-poor as well as resource-rich farmers, as managing agricultural productivity while maintaining or improving the resource base. This means that agriculture must be environmentally solid, economically feasible, socially scrupulous, and flexible (for future needs).

Introduction

Despite fact that more than two-third of the earth’s surface is covered with water, currently, near about 450 million people in 29 countries are facing severe water shortage and at least 20 percent more water would be required to feed additional 3 billion populations by 2025. About 97.5 percent of ocean-sea water is not available due to its salinity and 2.49 percent is locked up in ice and only 0.01 percent is technologically available and economically accessible water either from surface or ground water sources for human uses. So water saving technologies developed so far is very pertinent to propagate amongst the users. Water is an essential natural resource for sustaining the environment and supporting life where the agriculture is the major user of water resource. Water is an indispensable for sustainable agricultural growth and development. Previously, rainfed agriculturewas 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. Although there is a difference in the objectives of water management where there is abundant availability of water from continuous flow connected with perennial sources or lakes and rivers and that of from restricted or limited supply from collection of excess rain through water harvesting structures.The former is associated with to obtain as much as yield of crop per unit area under water application and later is associated with increasing productivityof crop per unit of water application even under rainwater recycling and its effective management for the purpose of irrigation. Hence, both the rainwater and irrigation water are considered to be equally important to context of agricultural development of the country to get higher water use efficiency and proper utilization of water resources (Zaman,et.al., 2017).

Introduction

Agricultural productivity during past three decades resulted in depletion of natural resource base besides creating several environmental and ecological problems. In contrast the demand scenario features a growth rate in food requirements to meet the ever-increasing demand of the growing population. The total food grain demand of India by 2020 is estimated at 294 million tones as against the present 224 million tonnes (2010-11), which has to come from the almost static net cultivated area of about 142 million ha. This improvement in food grain production has to be achieved while dealing with the factors affecting the ecological balance and sustainability of Agricultural resources. Soil and water conservation is an important aspect, which needs very careful dealing with proper attention of the researchers and planners particularly in the context of agriculture of rainfed areas. As the water without soils is useless for crop cultivation, the soils without water nothing but desert. At least 20 % of total land is deserted and very difficult to use with another 20 % is sandy and poor in nutrient content subjected to severe soil erosion and excessive land degradation which causes fragile nature of eco-system and threatens food security of such areas. Soil erosion reduces productivity and cuts crop yield and causes at least 10 metric tons of topsoil loss per hectare per year. Now days, soil and water conservation is gaining paramount importance globally due to its obvious reasons. The main objective of the subject to protect soils against damage due to excessive runoff by natural, mechanical, cultural and agronomic measures to be adopted to bring a state of equilibrium between climate, soil, rainfall, slope and vegetation.

Social disinterestedness could be an anticipation that applies issues of amends and candor to policy. Aback the Sixties, the anticipation of amusing disinterestedness have been activated in an advance of institutional contexts, calm with apprenticeship and accessible administration. The anticipation of amusing disinterestedness is about afflicted aback to the works of philosopher and Plato. Definitions of amusing disinterestedness will vary, about all focus aloft the ethics of amends and fairness. Disinterestedness in fashionable societies involves the role of accessible directors, United Nations bureau breadth assemblage accountable for authoritative assertive that amusing casework breadth assemblage delivered equitably. This bureau demography into application actual and accepted inequalities a part of groups; candor relies on this amusing and actual context.

10. 1 Land and Water Resource

India has got the world’s 2. 45% area and 16. 87% of population with only the 4% of available fresh water (Table 10. 1). This indicates the necessity of development of water resources and optimal use of it. India at macro level does not have short of water. But the shortage of water is due if not properly managed by conservation and sector wise utilization.

INTRODUCTION

Himalayan region is known for the diversity of its cultural heritage and climate. In Indian part, this mountain range includes states of Uttarakhand, Himachal Pradesh and Jammu & Kashmir. The climatic variability of the region,from sub-tropical to extreme dry temperate, offers great attraction to naturalists, all across the globe. The forest formations here are the natural habitats of a large number of flora and fauna. The flora found in these forests varies with the altitudinal gradient and is quite distinct. In the sub-tropical Himalayas, for example,the predominant vegetation is of deciduous type consisting of trees, shrubs, scrubs, climbers and xerophytes. Man-made Chir pine forests can also be witnessed. At middle elevation, the climate is sub-temperate and supports a mix of broad leaves and pines forests.In the high reaches including Trans Himalayas, climate is typically wet or dry temperate. In the wet temperate climate, evergreen forests are the predominant vegetation, whereas, the dry temperate areas do not support any significant vegetation.This variation in climate and altitude has a great impact on the biodiversity found in the region, and represents about seven percent of the country’s total biodiversity.

Among this diversity, many valuable and rare medicinal and aromatic plants grow wild in the region. The herbs which are traded from this region are of immense value for the preparation of Ayurvedic drugs in the form of monoherbal preparations or as multi-compound herbal formulations. Charak Samhita mentions that the herbs of the Himalayan forests excel in efficacy.

Carbohydrates are widely prevalent in the plant kingdom, comprising the mono, di-, oligo-, and polysaccharides. The common monosaccharides are glucose, fructose, galactose, ribose etc. The disaccharides, i.e., the combination of two monosaccharides include sucrose, lactose and maltose. Starch and cellulose are polysaccharides consisting of many monosaccharide residues. Cellulose is the most abundant organic compound on this planet since it forms part of the cell wall in plants.

Aldehydes (–CHO) and ketones (= CO) are active groups in carbohydrates. Carbohydrates contain many hydroxyl groups as well. The number of hydroxyl groups varies with the number of carbon atoms. Monosaccharides contain the free aldehyde or ketone group. Some disaccharides have the free aldehyde group (maltose) and some do not have the free ones (sucrose). The polysaccharides, starch and cellulose, are polymers of monosaccharides linked through the active groups. The chemical properties of saccharides vary depending upon the number of hydroxyl groups and the presence or absence of –CHO/= CO groups. These variations are the basis in the development of colour reactions to identify the saccharides. Some simple tests used to identify the presence/absence of certain saccharides are listed below:

ABSTRACT

Biotransformation is an essential step in the elimination of drugs and reduction of their toxicity. The use of fungi in biotransformation reactions can provide information about the metabolism of new drugs and facilitate the attainment of necessary amount of metabolites for toxicological and pharmacological evaluation. Biotransformation studies require the right choice of the microorganisms and also of the culture conditions (pH, substrate, oxygen, salts, temperature, etc). The optimization of these procedures is essential to achieve good results. The fundamental aspects of drug biotransformation by fungi are discussed here as well as some applications showing that many fungi are used in biotransformation studies, mainly Cunninghamella species. Several species mimic the mammalian metabolism producing the same metabolites observed in humans.

ABSTRACT

Plant growth promoting (PGP) bacteria play an immense role in promoting crop growth mainly by direct mechanisms such as N_2-fixation, phosphate solubilization and phytohormone production and indirectly may help to suppress pathogens or contribute to enhance absorption of nutrients leading to increase yields. The N₂fixers are grouped based on their niche adaptation as endophytic nodular symbionts (Rhizobium spp.), free living (Azotobacter spp.), associative symbionts (Azospirillum spp.) and endophytic non-nodular symbionts (Azoarcus and Gluconacetobacter diazotrophicus). In the recent past, phosphate solubilizing and phytohormone synthesizing bacterial communities also gained momentum.

ABSTRACT

Heavy metal contaminated soils are biologically inactive and extremely poor in soil fertility status. These metals are highly resistant and cannot be easily degraded by either chemical reactions or amendments. Microorganisms are biological softwares capable of degrading the metals efficiently. Among microorganisms, mycorrhizas are known to circumvent metal toxicities through a series of processes that assist in immobilization in biological systems which converts toxic metals into less or nontoxic forms. There are five mechanisms such as biosorption, solubilization, hyphal transport, detoxification and dilution are involved in promoting tolerance of host plants to heavy metal toxicities. These processes are strategies that can be exploited to phytoremediate the contaminated soils. The phytoremediation strategies encompass tolerance of mycorrhizal fungi, phytostabilization (preventing entry of heavy metals into plants), phytoextraction (luxuriant uptake and transport to shoots) and intercropping or crop rotation with mycorrhizal dependent hyperaccumulators or non-hyperaccumulators. Despite mycorrhizas are natural, the indigenous population is not sufficient enough to induce tolerance of host plants to abiotic and biotic stress conditions. This necessitates adopting recommended agronomic practices to promote mycorrhizal colonization in natural agro-ecosystem or to derive full benefits from phytoremediation strategies. Thus mycorrhizas are important naturally occurring microorganisms capable of withstanding highly contaminated metal sites and offer protection against phytotoxicities caused by heavy metals.

ABSTRACT

Worldwide reinterpretation of evolutionary history of sedimentary basins had commenced with the introduction of sequence stratigraphic concepts by geoscientists of Exxon. The eustatic sea level controlled deposition in sedimentary basins together with synchronous excursions of many trace elemental and stable isotopic compositions of sedimentary strata have led to a proposition that geographically widely separated sedimentary strata could be classified and correlated with ease by application of sequence stratigraphy and chemostratigraphy, relatively younger branches. This paper reviews the key definitions of these stratigraphic methods, presents an overview on their applicability in petroleum exploration, reservoir characterization and stratigraphic correlation. Considering the man-hours required for interpretation of sequences and chemozones from large quantum of core samples being generated from exploration activities and the possibility of human-error and biased nature of interpretations, an automation scheme involving statistical discrimination is suggested. The statistical discrimination method has been tested to have 76-100 % distinction of depositional units of Recent – Cretaceous in age in terms of sequences, chemozones, lithostratigraphic units, petrographic types and sedimentary microenvironments with 100% reproducibility of predictions. Hence, creation of a large database with well constrained subpopulations and putting it to use for recognition of depositional units and correlation of strata and reservoir characterization is suggested which may reduce operational inconsistencies and improve exploration strategies.

ABSTRACT

Mecheri Panchayat union lies in the northwestern part of Salem district and adjascent to Dharmapuri district of Tamil Nadu. It lies between the latitudes 11°43’ -12° and longitudes 77° 48’ -78° 03’ of Toposheet No. 58 E/13 of scale 1:50,000 published by survey of India in 1973. Mecheri Panchayat union covers a total area of about 177.6 Sq.Km with a population nearly 1 lakh, live in 150 hamlets. Groundwater is the only replenshable nature resources available to man. The use of groundwater has been growing steadily over the years for domestic, agricultural and industrial purposes. Hydrogeochemical study is a dynamic process undergoing constant change in space and time. In unconfined aquifers, the change likely to be quite rapid and cyclic in nature with respect to the mode of recharge and discharge and related to the nature of host aquifer. In this study an attempt has been made for understanding the chemical quality of groundwater in theunconfined aquifer of Mecheri union. Groundwater samples have been collected from 10 representative dug wells lying in the Mecheri union during December 2004 and analysed by the standard procedures of water analyses. It is essential in determining its usefulness for domestic, industrial and agricultural purposes. Presentation of Geochemical data in the form of graphical charts such as Collin’s bar, Stiff’s polygon diagram, Pie diagram, Piper tri linear diagram, USSL classification and thematical maps were prepared for recognizing various hydrogeochemical types in the Mecheri union. Deleterious effects of fluoride on the human beings are well known. Fluoride are known to be beneficial, when present in concentration ranging from 0.5 ppm to 1.2 ppm. But when it exceeds the limit 1.2 ppm it is found to cause fluorosis. Dental, skeletal and non-skeletal fluorosis may be caused depending upon the concentration of fluorides in drinking water. The main source of drinking water for the majority of people of Mecheri union is groundwater obtained through dug and bore wells. The analysis of groundwater samples showing high (> 1.5 ppm) fluorite content observed in the following villages, viz Mallikundam, Kuttapatti Aranganur, Banapuram, Sathappadi, Mecheri town, Virudasampatti and Amaram.

Abstract

The tsunami has struck many coastal countries of South Asia on 26 December 2004 and caused greater devastation along Andaman - Nicobar and Indian coasts. In India, Tamil Nadu coast is worst affected in Kanyakumari, Nagapattinam and Cuddalore districts. Subsequently, damage assessment, in respect of natural and physical resources, was done using Remote Sensing and GIS in parts of Cuddalore and Pondicherry coasts. The structural damages were studied village wise and categorized as maximum, moderate and least affected areas. As far as the natural resources are concerned, the changes in geomorphology, land use/ land cover, soil and water have been studied. On the basis of the same, the risk maps were also generated in GIS environment.

Abstract

Drying is a widely used method of food preservation. It leads to some structural changes in the dried material resulting in poor quality and rehydration. Freeze drying, though a costly process, reduces water activity without exposing the food material to high temperatures, eventually retains the original quality to a great deal. Moisture in the foods is frozen to ice which is sublimated under low pressure. Low pressure helps to vaporise the ice without transforming it to liquid, hence leaving the food structure porous in nature. The food is claimed to preserve the nutritional, sensory and re-constitutional qualities.

1.1 INTRODUCTION

Most food materials are composed of a very high percentage of water, which can be as high as 95%, and this makes them susceptible to microbial activity. Microbial activity spoils the products, leaving them useless for human consumption. It not only changes their taste and color but it may also develop toxins, thus making them unsafe. There are various methods for preserving food but in order to make them shelf stable, removing water from foods helps keep them from spoiling for a longer period of time.

Abstract

Drying is one of the most important industrial operations for preservation of food material. Due to the major limitations posed by convective drying methods, there is always a need for novel drying techniques which are technically, economically and environmentally sustainable. Based on the principle of moisture diffusion due to vapor pressure gradient, atmospheric freeze drying (AFD) offers a promising alternative to conventional drying systems. A cold gas with low water vapor pressure is used as drying medium to sublimate moisture directly from the frozen material at atmospheric pressure conditions. As a result the product gets dried at much lower temperature unlike convective drying. Thus, products dried with AFD retain better nutrition, texture and color and the process is also considerably cost effective. Major limitation of the AFD process is longer drying time, which can however be accelerated by using heat pump drying or new ultrasound technology. This chapter focuses on mechanism, benefits, limitations and comparative study of AFD with other drying methods such as hot air drying and vacuum freeze drying. It provides an insight regarding effect of AFD on properties of food material based on various studies reported in literature.

Abstract

Increasing global demand for ‘fresh-like’ processed food products has forced food industries to investigate into various minimal processing techniques. Food processing in general has been associated with thermal processing, alone or in various combination with chemical and mechanical preservation and processing methods. However, thermal processing methods are energy intensive in nature and tend to reduce product quality and freshness at the cost of shelf-life gain. Advance technique such as microwave, radio-frequency and freeze drying do maintain the product quality but their implementation at industrial scale involves high operational and maintenance cost. An ideal processing method therefore would be one that can process food products without losing its quality, is energy efficient and is easily scalable. In this chapter, we discuss about ‘Electrohydrodynamic (EHD) Drying’, which is can be classified as a minimal processing technique. The heat and mass transfer principles involved in EHD drying have been extensively discussed and so has been the key consideration for designing an EHD drying system.

DEFINITION

Pheromones are chemical produced as messengers that affect the behavior of other individuals of insects. The term pheromone was introduced by Peter Karlson and Martin Liischer (1959) and is based on the Greek pherein (to transport) and hormon (to stimulate) is a chemical that triggers a natural behavioural response in another member of the same species. There are alarm pheromones, food trail pheromones, sex pheromones. And many are others that affect behaviour or physiology. Their use among insects has been particularly well documented, although many vertebrates and plants also communicate using pheromones. Pheromones are chemicals released by an organism into its environment enabling it to communicate with other members of its own species.

India, as a developing country has reasons to be concerned about the adverse impact of climate change on its economy. A large part of its population depends on climate sensitive sectors for livelihoods which makes it highly vulnerable to climate change. Climate change can have serious impact on its crops, forests, coastal regions, etc. which can in turn affect the achievement of its important national development goals. The issue of climate change cannot however be taken up without linking it to developmental needs such as poverty, health, energy access and education. Traditionally climate change experts have focused on mitigation measures, adaptation measures have also been acknowledged of late as effective and equitable means to deal with climate change impacts. Most of the mitigation measures are high in terms of technology and capital. Therefore, while developed economies choose to mitigate climate change by making heavy investments, developing economies choose to adapt (Monika and Hooda, 2018). There is increasing recognition that the world’s current progress on reducing greenhouse gas emissions is not occurring rapidly enough to avoid impacts from climate change in the coming century. Because of this, the world is “committed” to a certain level of global warming and therefore, subject to a degree of impacts that will require adaptive responses by nations and communities (Bizikova et al., 2008). IPCC have specific observations on India in relation to climate change and its impact in its AR 5 Report. Several workers analyzed monthly, seasonal, annual temperature (1901-2007) and rainfall (1873-2011) variability for entire India over two different spatial scales of 30 sub-divisions and 7 regions of India. The net change in rainfall and mean temperature indicates decreasing rainfall and increasing temperature in most of the months and seasons. In India, an increase in temperature over the country and the subcontinent was observed. As discussed in Intergovernmental Panel on Climate Change (IPCC) 5^th Report (IPCC, 2014), the global ocean will continue to warm during the 21^st century, with the strongest warming projected for the surface in tropical and Northern Hemisphere sub-tropical regions. In addition, changes in precipitation will not be uniform (Pachauri and Meyer, 2014). In the light of these projections, it can be assumed that climatic pattern of Haryana can also undergo considerable changes (Anurag et al., 2017). Increasing trend of annual rainfall in Haryana was also reported by India Meteorological Department (Rathore et al., 2013).

Climate change is one of the most important global environmental challenges facing humanity and as per the instrumental records, the earth’s climate system has demonstrably changed on both global and regional scales since the preindustrial era. Further evidence shows that most of the warming (of 0.1°C per decade) observed over the last 50 years, is attributable to human activities. The levels of greenhouse gases namely carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) have increased markedly as a result of human activities. The CO₂ concentration in atmosphere is now more than 400 ppm and the decadal increase is from 0.86 ppm per year to 1.99 ppm per year (Table 16.1) which is the highest ever. The Intergovernmental Panel on Climate Change (IPCC, 2007) projects that the global mean temperature may increase between 1.4 and 5.8 ^oC by 2100. This warming of the earth-atmosphere system is expected to have severe impacts on the global hydrological system, ecosystems, sea level, crop production and related processes. Agriculture sector is the most vulnerable entity in light of the global warming and its impacts. Global mean temperatures of today are already about three quarters of a degree warmer than that of preindustrial times, and even if carbon emissions were completely stopped today the warming trend would continue for many decades. Moreover, the United Nations (2015) report has projected the world population to increase from current 7.3 billion to 8.5 billion (16%) by 2030, 9.7 billion (33%) in 2050 and 11.2 billion (53%) in 2100. With more population to feed the agriculture of tomorrow will be at cross roads if it is not sustainable as well as productive. Since the beginning of the early civilizations, agriculture and its adaptation to climate change or anything else is an ongoing process. On a long term basis, the agricultural crops will have to adapt to at least a warming of about 2^oC. These low cost adaptations in agricultural crops (such as changes in sowing periods / dates, cultivars, fertilizer and irrigation use and crop management practices) can reduce the impact on crop yields by often more than half, relative to the cases of no-adaptation.

The State of Himachal Pradesh encompasses a geographical area of 55.7 lakh ha and is situated between 31°22’40" and 33°12’40"N latitude and 75°45’55" and 77°10’20"E longitude. The state is bordered by Jammu and Kashmir on the north, Punjab on the west, and Haryana on the south-west (Fig. 19.1). About 12 per cent of the state area is under agriculture which is mostly (80 per cent) rain fed. Wheat, maize, rice, and barley are the principal crops. In state, there are 12 districts, viz., Bilaspur, Chamba, Hamirpur, Kangra, Kinnaur, Kullu, Lahaul & Spiti, Mandi, Shimla, Solan, Sirmaur and Una. About 20 per cent of the area is under forest cover. It is rich in biodiversity of flora and fauna. Nearly 27 per cent of the area of the state is covered under permanent pastures. The state is endowed with a wide range of physiography/landform, climate, vegetation and geology which have influence on genesis of soils. The soils are mostly shallow, medium deep to deep, well/excessively drained, sandy, sandy-skeletal, loamy-skeletal, coarse-loamy and fine-loamy, calcareous as well as non-calcareous with low available water capacity. The State is the biggest montane ecosystem in India situated in northern part of the country. It is seventeenth largest state in terms of area and twentieth in population of which 65 per cent people are dependent on agriculture and 60 per cent of GDP comes from agriculture sector. Increasing temperature and reducing rainfall affecting the crop growth and crop production is a major issue everywhere in the world nowadays and this state has also not remained untouched by these prime issues of climate change. For sustainable development of agriculture in state, there was/is a need to identify and quantify climatic change where agriculture has a significant influence on both the economy and livelihood.

The United Nations Framework Convention on Climate Change (UNFCCC) defines Climate Change as a change the weather parameters attributed directly or indirectly to human activity, altering the composition of the global atmosphere. Human activity includes the pollution that arises from industrial activity and other sources that produce greenhouse gases. These gases, such as carbon dioxide, have the ability to absorb the spectrum of infrared light and contribute to the warming of our atmosphere. Once produced, these gases can remain trapped in the atmosphere for tens or hundreds of years.

The green buildings are the needs of present day in India as well in the world. The easy availability of most of the green materials and equipments in the country has made it easier for designers to adopt local materials to a very large extent in the construction of green buildings. Now, there is an imminent need for service providers, who would be required in large number, not in hundreds but in thousands, as the movement is heading to reach greater heights. The green building movement is here to stay for the benefit of individuals, society and the country at large in the era of climate change.

With increase in the urbanization and industrialization, there is more pressure on available land and natural resources. In coming era, there will be only limited space available for city dwellers. In buildings one can grow a wide range of flowering and foliage plants. Plants not necessarily one confined to the outdoor only but bed room, kitchen, staircases, patios, windows and other locations can be made green with suitable plants. Indian Council of Green Building (ICGB) has developed the rating system.

Green Building in Santiago, Chile

A large amount of materials are used and energy consumed in construction and operation of average building. Many steps have been taken to reduce consumption of energy by developing new types of vehicle, energy sources, recycled materials and designing environment friendly buildings. These buildings are also known as green buildings or green construction or sustainable building.

Introduction

Bougainvillea is a popular ornamental plant in the tropics and sub-tropics of the world. The plant is mainly grown for its attractive bracts in wide array of colours which splash colour to the surrounding where it grows. Wide adaptability to different agro-climatic conditions and easy multiplication has made it a popular ornamental plant of the world. The mass effect of the colourful bracts of Bougainvillea can alter the face of any given place in a magnificent way which could not be achieved by punctuating any other plant. The flowering of Bougainvillea is compared with the Azalea of temperate countries and very truly called as Glory of the Tropics.’

The popularity of Bougainvillea has now crossed from tropical to temperate countries and successfully being grown as pot plants in green houses. Selection of cultivars of Bougainvillea spectabilis and B. peruviana for temperate region is recommended for better result. Availability of a large number of cultivars under horticulturally important species, provide a unique scope to the Bougainvillea lovers for wide choice according to their need. Single bracted cultivars with large bracts in different colours are obvious choice for every landscape designer while double bracted cultivars produce mass effect of colour as specimen plant. Considering its ornamental and commercial importance in nursery trade, R & D work were taken up by different national research institutes (IARI, IIHR, NBRI, BARC), agricultural universities, Agri-Horticultural Societies (Kolkata and Chennai) and even by progressive nursery men. As a result, a large number of new cultivars have been developed in India. Considering the contribution made by India, The international registration authority for new cultivars lies with The Indian Agricultural Research Institute (IARI), New Delhi which is an international recognition conferred upon by International Society for Horticultural Science.

Recently, lot of development taking place for further popularization and exploitation of Bougainvillea around the world by way of development of new cultivars, standardization agro-technology suited to different zones. Countries like Thailand, Singapore, Malaysia and India have been excelling in this area. Establishment of American Bougainvillea Society is another landmark in Bougainvillea cultivation.

Chemicals which are used specifically for the control of mite pests are known as acaricides, though there are many insecticides, which show acaricidal properties as well. In the last few decades, there has been tremendous progress in the development of broad-spectrum acaricides i.e. the compounds that will knock down different species of mites at the same time. Prior to the commercial introduction of broad-spectrum insecticides like DDT and other organochlorine insecticides, mites did not commercially cause wide-spread damage under natural or semi-natural environments which were little influenced by man. This might be due to the natural processes of prey-predator relationship in undisturbed situations. Contrastingly in situations where broad-spectrum pesticides are commonly used, the natural enemies are more adversely affected than the mites, and an outbreak of the latter occurs. Besides becoming generally intensified with the introduction of modern insecticides, the mite problem in some cases has subsequently become even more serious due to development of resistance against these materials.

Many spider mite species, which were rarely found in pest form in some situations, appeared commonly as major pests with the persistent use of pesticides. In Indian literature, spider mites were never reported in pest form prior to 1940 but with the intensive use of pesticides, every year new mite problems are appearing and becoming troublesome to control.

What is seed?

“A seed is an embryo, a living organism securely fixed in the supporting or the food storage tissue.”

A true seed is defined as “Structurally a true seed is a fertilized matured ovule, consisting of an embryonic plant, a store of food and a protective seed coat, a store of food consists of cotyledons and endosperm”. In broad sense, “seed is a material which is used for planting or regeneration purpose”. Scientifically, “seed is a fertilized matured ovule together covered with seed coat is called seed” or “it is a propagating material i.e., part of agriculture, sericulture, silviculture and horticultural plants used for sowing or planting purpose”.

The business of Seed Technology is to protect this biological entity and look after its ‘welfare’, while the focus of Food Technology is on the second component – the supporting tissue.

Introduction

Seed is a critical and vital input that draws an explicit line between the success and failure of any agricultural production programme. In fact progressive history of agriculture has been a history of seed development and production. The mankind has been attempting to select better seed and employ better seed production techniques volitionally or in-volitionally ever since it divested nomadic life for the settled one. Initial attempts were confined to selection of useful crops followed by selection of better sorts and land races among the available native genetic resources. The introductions, hybridization followed by selection of better types and modern breeding tools inclusive biotechnological interventions have been extensively employed to breed better seed. Considering that research in crop improvement can turn little stone unless the quality seed with desired attributes is made available to the farmers. Government of India set up enforcement of provisions of Seed Act, 1966 for certification of seed as per prescribed minimum standards. Central Seed Certification Board was established in 1972 to exhort the central and state governments for producing genetically and physically pure and physiologically viable seed. The seed production programmes and rules were progressively honed to meet the ground situations. Initially the seed was considered as the exclusive bastion of public sector but the private sector got actively involved in seed production. WTO the seed still became a very open subject and the Seed Act was modified in 1988 and 2001 to permit import and export of quality seed, respectively. Despite of all these positive developments in seed sector, the availability of seed is still far from satisfactory. As on today private sector dabbles in low volume high cost seed due to economics and storage factors but the high volume less cost is still a virgin for private sector and is predominantly done by the public sector. Crop improvement is no more an art and science of improving hereditary of crop plants but has become a starker and competitive business under which the stronger would survive and the weaker get eliminated.

Business was abysmally shattered at the terminal end of the Second World War. This forced some nations to sign some tariff related global

ABSTRACT

Traditional herbal drug preparations are known for centuries to protect several human diseases such as peptic ulcer, diarrhea, piles and dysentery. Current days knowledge about the underlying biochemical mechanism for most of the gastric ulcers and majority of the duodenal ulcers deserve appropriate consideration and due weightage while consolidating regarding the efficacy of a plant extract. The present investgation relates to a pharmaceutical composition comprising an effective amount of lyophilized extract or at least one bioactive fraction obtained from flowers of Woodfordia fruticosa (L.) Kurz, along with one or more pharmaceutically acceptable additives or carriers. The present results provides a composition for treating ulcers such as stress induced ulcer, peptic ulcer, cold restraint induced ulcer, drug induced ulcer and acid induced ulcer, and also the composition used as specific inhibitor of gastric H+, K+-ATPase. Herbal formulation in the form of capsules were conducted on marker-based stability studies as per ICH Q1 guidelines at accelerated and real time stability studies (40±2°C, 75% ± 5% RH and 30±2°C, 65%±5% RH, respectively), and also stability testing investigation was done as per stability specifications at intervals of 0, 3, 6 months for accelerated stability studies and 0, 3, 6, 9, 12, 18, 24, 36 months for real time stability. The present data reveals that this species is one of the potent Indian medicinal Plant which helps in curing ulcer and associated diseases.

ABSTRACT

Due to the exorbitant price of the popular gelling agent agar, Plant Tissue Culture (PTC) has gradually become a costly technique in recent times. So, alternative sources of agar needs to be popularized which at one hand should be able to meet all the positive properties of agar and on the other hand be cost effective as well. The seed husk obtained from Plantago ovata Forsk. is such an alternative which was successfully used as a gelling agent for media preparation in PTC experiments for in-vitro shoot and root development in Nicotiana tabacum L. and Ocimum gratissimum L. The nodal explants were grown in MS basal medium (MSo) supplemented with 3% sucrose and were gelled with progressive concentrations of isabgol husk to ascertain the optimum concentration for better survival and growth response, while 0.8% agar acted as a negative control. The response of the explants on media gelled with husk was compared to that of media gelled with 0.8% agar. It was inferred that 0.3% husk in the medium was optimum for best growth response which was comparable to that of agar. Consequently, the estimated cost of a liter of MSo reduced by almost Rs.61.15/- (compared to Himedia’s Agar) to Rs.177.57/- (compared to Sigma’s Agar) after using isabgol seed husk as a gelling agent in media preparation.

ABSTRACT

Zanthoxylum armatum DC. is a plant species belonging to flowering family Rutaceae which has medicinal application in traditional Ayurvedic system of medicine. It is characterized by trifoliolate leaves with leaf-stalk winged, branches with straight prickles, and fruits are small reddish brown. In India, tribal community used this species as carminative, dyspepsia, tooth curing, treating malaria fever, stomach pain and expelling roundworms. Chemistry indicates that Z. armatum is a repository of many chemical compounds such as alkaloids, flavonoids, sterols and triterpenoids. Zanthonitrile, berberine, α-sitosterol, armatamide, limonene and linalool are major constituents. Leaves and young shoots yield essential oils which act as anti-bacterial, antifungal and anthelminthics, and has tremendous potential in development of value added products. Volatile oils are active constituentsof linalool, limonene and ligan. Z. armatum has been declared as an endangered species as per International Union for Conservation of Nature and Natural Resources(IUCN) Red List category. Conservation practices needs to be adopted to conserve this valuable medicinal plant. There is a need to study on ecology, adaptive biology, chemistry and biotechnological intervention for future propagation and conservation of this medicinal plant species.

ABSTRACT

Panax L. is an important medicinal plant species complex, which is commonly known as ginseng. Ginseng has high commercial value for itsginsenoside contents and is collected from the wildin the subtropical-temperate forests of north-eastern India. Taxonomy, ecology and phenology of five species of Panax found in north-eastern India viz., P. assamicus R. N. Banerjee, P. bipinnatifidus Seem., P. pseudoginseng Wall., P. variabilis J. Wenand P. sokpayensis Sharma& Pandit, have beendiscussed in this paper. The distribution of these species is restricted to the states of Arunachal Pradesh, Manipur, Meghalaya, Nagaland, Sikkim and Darjeeling HillsofWest Bengal.P. pseudoginseng hasextended distribution range in Nepal. P. variabilis was reported from Nagaland, which is a new record for India. All the species of Panax prefer shady and moist habitat. The species grow in the soil texture that ranges from loamy sand to sandy. The pH ranges from 4.3-7.1. The species is perennial and pereniates through its underground rhizome. The phenophase starts with emergence of seedlings in the late March and senescence takes place in the middle of October after seed setting. Monitoring of the populations of all Panax species revealed that the population size have decreased by 40-50% over a period of 10 years due to over-harvesting from the wild by the local people for its medicinal value. Sustainable use of rhizome and its cultivation practice need to be standardized to address the conservation issues related to the plant.

ABSTRACT

Systematic studies through stored specimens in herbaria and museum of defined geographical areas provide a set of baseline data for understanding the vegetation composition of a defined ecosyetm. A stored plant collection in herbaria offers a rich portrait of biodiversity, making innumerable contribution to science and human society. Digitization coupled with hosting of such information on world wide web (www) system has been accepted as an important tool for the dissemination of the botanical specimens in the form of databasing, imaging and geo-referencing of voucher specimens. In the present communication, we describe the development of the Janaki Ammal Herbarium (JAH) database that contains a comprehensive and searchable data of voucher snaps, historical background and statistical analysis of 23,225 voucher specimens. The information on JAH database is easy to extract data on botanical names, author citation, variety (if any), family, collection number, specific location, collection date, habitat, collector’s name and remarks on morphology. The goal of the present investigation is to digitize (database, image, georeference) all specimensin JAH, enabling themto be made available through a single portal. At concluding, all vouchers of JAH made publicly accessible via world wide web user interfaces, and also linked to PubMed, NCBI Taxonomy, where the site provide information related to Entrez records, comments and references of the particular species, while Wiki species site is linked to the free species directory. It also provide link of online accessible herbarium-based databases of the world.

1. Introduction

The scientific naming of plants is called botanical nomenclature. Although, nomenclature is included in taxonomy, but it distinctly differs from taxonomy. Plant taxonomy is concerned with grouping and classifying plants, however, the botanical nomenclature provides names for the results of this process. Names are a means of reference to all living and non-living things. The common names of pants and animals vary from place to place and language to language. But, scientific names of plants and animals are universal. For uniformity and consistency, the scientific names are given to plants according to certain internationally accepted rules provided in International Code of Nomenclature. It was Linnaeus who for the first time proposed some rules for generic names of plants in his Fundamenta Botanica, 1736 and Critica Botanica, 1737. However, the first proper set of rules of plant nomenclature was drafted by A. P. de Candolle and passed by the International Botanical Congress at Paris in 1867. The present Botanical nomenclature is governed by the International Code of Nomenclature for algae, fungi, and plants (ICN), which replaces the International Code of Botanical Nomenclature (ICBN) in 2012.

Botanical nomenclature has a long history, going back to the period when Latin was the scientific language throughout Europe, and perhaps further back to Theophrastus. The starting point for modern botanical nomenclature is Linnaeus’ Species Plantarum (1753). In the nineteenth century it became increasingly clear that there was a need for rules to govern scientific nomenclature and initiatives were taken to produce a body of laws. These rules were published in successively more sophisticated editions after every six years. The most recent is the Melbourne Code, adopted in 2012.

All formal botanical names are governed by the ICN, and within the limits set by that code there is another set of rules, the International Code of Nomenclature for Cultivated Plants (ICNCP). The latter Code applies to plant cultivars that have been deliberately altered or selected by humans and require separate recognition

1. Introduction

Seeds have complex and remarkable diversity in shape, size, colour and morphological and anatomical sculpturing details of seed coat, which are valuable for taxonomic significance and can be used as an additional parameter combined with other parameters during taxa identification and classification. Distinctive seed coat morphology usually allowing identification of species even solely on the basis of seed characters. All members of a particular taxon possess variation within acceptable limits of their description and can be used for identification purposes. High structural diversity provides most valuable criteria for classification between species and family level. Takhtajan (1959) pointed out that even for the phylogenetic correlation between families and genera, the structure of the seed coat might be important. Most taxonomists agree that data concerning the structure and microstructure are of great significance mainly for the classification of angiosperm taxa. Consequently, in addition to vegetative and reproductive characters, seed characters are being used in most of the studies for the analysis of taxonomic relationship in wide variety of plant families. It was observed that seed morphology and anatomical features are rather conservatives, which makes them taxonomically important (Esau 1977; Barthlott 1984).

Gaertner (1788-1805) was the first botanist to use seeds and fruit morphology for comparison and identification of different taxa. Later on, Harz (1885) presented a comprehensive account of seed structures and their individual characters of different taxa. In the 20^th century interest in legume seed morphology was renewed. Capitaine (1912) studied the seed morphology of entire family and concluded that seed morphological characters are helpful in legume classification and identification at the tribal, generic and specific levels. After 40 years of Capitaine, Jensen (1998) documented 27 publications on seed morphology. Gunn (1981) summerized the seed characteristics for 510 legume genera. Seed characters of seventeen families were compared by Isley (1947). Duke (1961) indicated that seed shape, sculpturing and colour provide a critical indication of the systematic position of species of Drymaria (Caryophyllaceae). Obermeyer (1962) pointed out that the only reliable distinction between the two genera Chlorophytum and Anthericum of Liliaceae appears the number and shape of seeds. Hairy outgrowth on the testa, their length and colour provide useful characters in the distinction of genera/species in Malvaceae, Convolvulaceae, Asclepiadaceae and Acanthaceae. Gunn (1970, 1971) divided one hundred species of Vicia into major and minor groups on the basis of seed size, shape and length of the hilum, lens position and seed coat pattern and sculpturing. He successfully employed these characters up to specific level. Gunn and Gaffney (1974) studied the seeds of 42 economically important taxa of Solanaceae, including hilum and surface pattern as key character. Later on Gunn and Barnes (1977) had also used seed characters in the delimitation of Erythrina species. Seavey et al. (1977) studied the seeds of 210 species of Onagraceae, where seven seed groups were recognized and their evolutionary implications were also discussed. Matthews and Levinus (1986) demonstrated fairly constant seed characters in those species of Portulacaceae which have restricted geographical distribution, whereas the seeds of species with wider geographical distribution show varied morphological structures.

Fraudulent substitution of meat is the adulteration or mixing of the inferior or cheaper quality meat into superior quality meat. The first case of fraudulent substitution was recorded in thirteenth century A.D. at Florence in Italy. A common fraud in the meat industry in which uninspected meat is substituted for meat that has undergone inspection and been branded as satisfactory. The other frauds are the substitution of meat of another species, e.g. horse for beef especially in Britain and Ireland, beef in kangaroo meat in Australia, cat for chicken or rabbit, goat meat for mutton, mutton for venison, dog meat and cat meat for chevon in other countries including India. As per an estimate about 25-30% of meat sold in India is adulterated. These practices are more common in comminuted meat products. These illegal practices are punishable under PFA act 1955. The choice of method to be applied is depend on the need or condition of meat recovered.

Physico-chemical and microbiological quality of meat and aquatic food and food products gives its overall safety and quality status as a food. The physico-chemical and microbiological qualities of raw material have great importance on the product development. It also affects the shelf life of the raw material as well as final product.

Fresh meat is a type of meat which has not been subjected to any processing whereas raw meat is a fresh meat which has undergone freezing. The qualities of fresh meat are important as far as merchandiser, purchaser and consumers are concerned and it is also important for adaptability in further processing. The important quality parameters of fresh meat are:

Meteorology is derived from the Greek word meteoro which means above the earth’s surface; i.e., the atmosphere. The state of the atmosphere experienced at a given time, in any location on the surface of the earth is known as weather. Thus meteorology is the scientific study of the atmosphere or the weather. It is a branch of physics dealing with atmosphere and it is often quoted as the ‘physics of the lower atmosphere’. The main focus of meteorology is to understand the weather processes and forecast the weather. Solar radiation, the air mass and moisture are the three key ingredients that make up weather. The exchange of heat, moisture and momentum between the earth’s surface and the atmosphere determines the characteristic of weather. The observable weather events are known as meteorological phenomena and are defined by a set of variables called weather elements. Atmospheric temperature, atmospheric pressure, humidity, precipitation, cloudiness, wind and visibility, etc. are examples of such weather elements. The weather elements are not separate entities. They are closely related with each other and are highly variable in nature. Meteorology explains and analyses the changes of these weather elements.

Meteorology

The major subdivisions of meteorology are dynamic meteorology (or atmospheric dynamics) and physical meteorology (or atmospheric physics). The dynamic meteorology is concerned with the analysis and interpretation of the three-dimensional, time-varying, macro scale motions and energy transformations in the atmosphere. The science of dynamic meteorology is meant to develop models based on the hydrodynamic and thermodynamic equations. The physical meteorology is concerned with the processes that alter the physical properties and the chemical composition of air parcels as they move through the atmosphere.

Meteorological hazards are severe and extreme weather and climate events that occur in all parts of the world, although some regions are more vulnerable to certain hazards than others. Meteorological hazards include cyclones, droughts, floods, hurricanes, hailstorms, heat waves and tornadoes. The hazard is distinguished from an extreme event and a disaster. An extreme event is simply an unusual event; it does not necessarily cause harm. A disaster is an event that does cause harm in significant amounts. Meteorological hazards are often called as natural hazards. The natural hazards become natural disasters when people’s lives and livelihoods are destroyed.

Hydrological hazards are the result of either excess or a severe lack of water, i.e., flood or drought. Hydrometeorological hazard is a process or phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage. Human and material losses caused by natural disasters are a major obstacle to sustainable development. By issuing accurate forecasts and warnings in a form that is readily understood and by educating people about how to prepare against such hazards, before they become disasters, lives and property can be protected.

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Weather forecasts are made by collecting quantitative data about the past and current state of the atmosphere on a given place and using scientific understanding of atmospheric processes to project how the atmosphere will evolve on that place. Weather warnings are important forecasts because they are used to protect life and property. Forecasts based on temperature and precipitation is important to agriculture.

Agricultural production is highly dependent on weather, climate and water availability, and is adversely affected by weather and climate related disasters. In many developing countries where rainfed agriculture is the norm, a good rainy season means good crop production, enhanced food security and a healthy economy. Failure of rains and occurrence of natural disasters such as floods and droughts can lead to crop failures, food insecurity, famine, loss of property and life, mass migration, and negative national economic growth (Sivakumar, 2006).

Farming in many parts of the world, especially in the arid and semiarid regions is risky, because climate is highly variable. In some developing countries as much as 80% of the variability in agricultural production is due to the variability in weather conditions. This production variability in agriculture has immediate and important macroeconomic impacts. A timely seasonal forecast of favourable conditions could permit farmers to adjust cropping patterns and input use in order to benefit fully from these conditions. Also, a timely forecast could give the marketing system and downstream users, such as the food processing industry, time to prepare for a bountiful harvest (Arndt et al., 2000). It is important to remember that under rainfed conditions, even a less reliable, but earlier forecast may be more valuable than an accurate but late forecast (Mjelde et al., 1998).

Abstract

Entrepreneurship essentially involves economic and dynamic activities, risk- assuming and idea generation that help in developing, organising and managing a business opportunity for profits. Entrepreneurship in agriculture is not merely confined to farm activities but also involves activities interlinked and interdependent with core and peripheral agricultural activities. Impediments in the pathway of agricultural entrepreneurship in West Bengal are characterised by fragmented landholding, low financial resources and thereby debt stickiness & dependence on short-term agricultural loan. Though disbursements of short-term credit have increased substantially, the rate of increase is low. For most farmers, insurance for financial or crop crisis is unheard or have hardly any implication. The paper tries to explain the performance of various agricultural insurance schemes in terms of coverage and the benefits being delivered in India and in West Bengal. The paper analyses whether the recipients consider the schemes as an effective risk mitigation tool or merely a habit of credit-dependence in West Bengal through a diffusion model. The paper concludes with the focus on possible entrepreneurial opportunities that may offer more customised agri-insurance policies, where regional disparities could be considered and individual interests be given little more importance.

Abstract

Out of 1.37 billion populationof India 67 % lives in rural areas whose major source of income is agriculture and allied activities (World Population Review, 2019). In simple words, the livelihood of this vast majority is closely related to rural enterprises. Fostering rural entrepreneurship may be affected by several issues, infrastructure being one of them. This paper attempts to examine the relationship between infrastructure investment by the state and rural entrepreneurship in India, with ‘Gross Fixed Capital Formation’ and ‘Agriculture, Forestry, and Fishing, Value Added’ considered as proxy variables. Time series econometrics is compiled with the data collected from World Bank Database for the period of 1961-2017. The study has established evidence in support of greater investment in infrastructure enhancing rural entrepreneurial opportunities in India.

Abstract: Ornamental salvia, native to Brazil is cultivated as bedding plant in the world. Many species have horticultural, commercial and medicinal values. Continued breeding and improvement of salvia is focused on disease resistance, new flower colours, seed oil content and abiotic stress tolerance. Interspecific hybridization is hampered by genomic differences, heterostyly, self incompatibility and low seed set. Breeders have created polyploid cultivars and mutants which have high ornamental value. Continued use of these and other modern techniques will ensure creation of new phenotypes for the market.

Keywords: Salvia, polyploidization, male sterility, inheritance, seed production.

Abstract: Tuberose, native of Mexico, occupies prominent position due to long spikes of fragrant flowers, potential in perfume industry and nearly year round growth in tropical and sub-tropical climate. Flowers are used for artistic garlands, floral ornamentals, bouquets and cut flowers for table decoration. Flowers remain fresh pretty long time and stand long distance transportation. Lack of genetic diversity in flower type, size, colour, self incompatibility, sterility, low seed set and limited information on genetics of characters pose significant challenges to breeders. Breeding objectives with high priority include dwarf plant type, novel colours, attractive forms for pot culture/ bedding purpose intense fragrance and high essential oil content. Only two white flowered cvs. Single and Double types are cultivated for commercial production. Salient breeding achievements through planned hybridization and mutation breeding are discussed.

Keywords: Polianthes, cultivars, interspecific/ intervarietal hybridization, transgressive segregants, gamma rays.
