Abstract

The growth story of any economy depends upon availability of financial services; finance is the life blood of economy and financial system work like the heart of the economy to ensure availability of finance. Efficient mobilization of household saving and effective allocation to the growing credit requirement of the economy helps in sustainable development of the country. Government RBI and banking sectors are making tremendous effort to bring every section of the country into the mainstream financial system. Still there exists a significant gap between the growth expectations and the ground realities in context of ‘mobilization and utilization of funds’ that support inclusive growth of the country. There is also a significant disparity among the people of rural and urban area in availing the services of the financial system. There is a need of effective tools to bridge the gap and bring in every section of people from all parts whether rural or urban to take part in the mainstream financial activities. Mobile technology can act as a tool to develop a platform which helps us to extend the financial services in remote areas. Technology intervention helps banks to reduce their cost, to increase customer reach ability and in better management of business risk. E-wallet can be a good platform to penetrate the financial services.

Abstract

Climate variability/change is one of the very significant concerns discussed in the recent two decades. Its impact on air temperature and precipitation has received massive attention worldwide as they affect both the spatial and temporal patterns of water availability. Hence, it is becoming clearer that analysis of trends in air temperature and rainfall is significant in studying the impacts of climate variability/change for water resources planning and management. Therefore, the aim of the study was to detect theannual, seasonal and monthly trends in air temperature and rainfall in the Râmgangâ river basin. Daily air temperature (Bareilly and Moradabad) and rainfall data (Shahajahanpur, Bareilly, Bareilly BPO and Moradabad)of 40 years (1971 to 2010) were used for the study. Non-parametric Mann-Kendall test and theTheil-Sen’s Slope Estimator was used for determination of estimating the trend and magnitude of the trend. Findings revealed that the basin is experiencing a warming trend because of the rise in themaximum and minimum air temperature. In case of rainfall, Moradabad showna significant high positive trend during the monsoon season. This would alter the river run-off in long run if the existing trend continues to persist like this.

Abstract

Nitrogen is an important nutrient for growth and development of plants. Presence or absence of nitrogen often affects the amino acid composition of proteins, which may in turn change its nutritional quality. Increase in the elevated CO₂ concentration and temperature associated with future climates are expected to affect the nitrogen use efficiency (NUE), growth and grain yield of wheat (Triticum aestivum L.). Atmospheric CO₂ is steadily rising from the current level of approx 384 µLL^-1 and is expected to rises upto 550 µLL^-1 by 2050. It is predicted that the global temperature would increase by 1.5- 4.5^oC. The main future challenge is to feed nine billion people under an altered climate, as this increase in global temperature would affect, negatively or positively the future crop productivity including wheat depending upon the geographical location. The present book chapter summarizes the potential impact of elevated CO₂ and temperature on NUE of Triticum aestivum L.

Abstract

Climatic variability with respect to total annual precipitation, mean maximum and mean minimum temperature as well as phytosociological characteristics of various herbaceous plant species of two distinct landscapes, ie, BudhaPushkar (BP) as sandy and Nasirabad Valley (NV) as rocky gravel, of Central Aravalli region was compared over a long period of time (1957-2012). Analysis of climatic data indicates reduction of total precipitation of 50 years by 1226.2 mm. There has been a ‘shift’ in monsoon season. However, a significant increase (36.8%) in precipitation was noticed during the winter season of last five decades. Data on total mean maximum temperature also showed significant variation. A rise of 2.5⁰C was recorded while compared the periods 1971-1990 and 1991-2011. Study showed a notable increase in the mean maximum and mean minimum temperature in the region. An assessment of changes in plant diversity at two landscapes was carried out over a period of 35 years (1976 and 2012). The phytosociological characteristics were compared for these selected years. It was observed that climatic variability have changed the order of dominants and other species with respect to frequency, density and IVI of herbaceous species at both BP and NV landscapes. Total number of species increase for BP landscape while decreased for NV stands, while numbers of invasive species are increased for both the landscapes over a period of 35 years.

Marketing Channel

Marketing Channel is an organised network of agencies and institutions which in combination perform all the activities required to link producers with users to accomplish the marketing tasks.
Marketing channel is the route taken by a product as it moves from the producer to the consumer.
It is a part of value chain – what the customers are prepared to pay for goods and services and all activities carried out in chain.
Marketing channels are sets of interdependent organizations involved in the process of making a product or service available for use/consumption. Channels normally describe a forward-movement of products from sources to user. Reverse flow channels is used to reuse or recycle products, and to recycling or disposal of solid waste (ecological goods).

Abstract

Aquifers are usually composed of permeable layers that can ways a considerable amount of groundwater. Usually, aquifer units are correlated through the concept of lithostratigraphy. For low-permeable aquifers, it is difficult to define the spatial distribution of hydrogeological units, and this study attempts to use geochemical methods to identify the groundwater flow paths in an area of Southeast coast of Tamil Nadu, India. Multiple geochemical analyses, including groundwater chemistry; stable isotopic compositions of d¹⁸O and 8D contents were performed.  Spatial distribution of d¹⁸O, dD, Cl-/HCO-₃ show that northeastern part of the study area seriously affected by seawater intrusion. The highly permeable aquifers at the east coastal region are characterized by high hydraulic conductivity as compared with other regions of the study area. Hydrogeochemical characteristics based on bivariate diagrams of major and minor ions show that changes in the chemical composition of groundwater are mainly controlled by the salinization process followed by cation-exchange reactions.

2.1 Introduction

The word Nanotechnology has originated from a Greek word which means “dwarf” and nanometer is one billionth of a meter (1 nm = 10^-9 meter). The nano-scale is not just another step toward miniaturization but a qualitatively new scale. The new behiviour of matter at nano-scale is dominated by quantum mechanics, material confinement, large interfacial volume fraction and other unique properties, phenomenon and processes. At nano-scale, physics, chemistry and biology converge towards the same principles and tools. Nanotechnology cannot be considered as a discipline in science or technology but it is domain in science and technology. Nanotechnology is a multidisciplinary area, any scientist, engineer, medical doctor can do research on nanotechnology. Presently, it is more of a science and less of a technology because of a lack of proper tools for studying the properties of nano-material. There is an immediate need to convert this science into technology and get out of this transition stage.

9.1 Introduction

Nanoparticles (NPs) are particulate matter with at least one dimension less than 100 nm (Christian et al., 2008). Although NPs are naturally present in the environment, manufactured NPs may have distinctive surface properties and chemistry in comparison with natural NPs (Handy et al., 2008). Manufactured NPs have a large area-to-volume ratio and size-dependent properties, which impart novel properties and behaviors that make them suitable for nanotechnology applications (Auffan et al., 2009). Range of applications for NPs has brought about a rapid development of the nanotechnology industry.

11.1 Introduction

Nanotechnology is the manipulation or self-assembly of individual atoms, molecules, or molecular clusters into structures to create materials and devices with new or vastly different properties. Nanotechnology can work from the top down (which means reducing the size of the smallest structures to the nanoscale e.g. photonics applications in nanoelectronics and nanoengineering) or the bottom up (which involves manipulating individual atoms and molecules into nanostructures and more closely resembles chemistry or biology). The definition of nanotechnology is based on the prefix “nano” which is from the Greek word meaning “dwarf”. In more technical terms, the word “nano” means 10-9, or one billionth of something. It is a very promising new branch of small-scale technology named for the unit of measure at which it operates: the nanometer. Nanotechnology enables us to create functional materials, devices, and systems by controlling matter at the atomic and molecular scales, and to exploit novel properties and phenomena. Consider that most chemical and biological sensors, as well as many physical sensors, depend on interactions occurring at these levels and you’ll get an idea of the effect nanotechnology will have on the sensor world.

15.1 Introduction

It is important that we understand some terms like clay, mineral, clay mineral, activated clay, and nanocomposite clearly. In fact, “clay” is a soil separate consisting of particles of <2 µm (equivalent to <0.002 mm) in equivalent diameter (Brady & Weil, 2002; pages 18-19) in both USDA and International systems. While in nanotechnology, uniqueness of micro- and nana- aggregates is of crucial consideration. (In Chapter 8: The Colloidal Fraction (Brady & Weil, 2002) size dimensions of minerals are given eliminating any chance of confusion.) Now let us look at some definitions provided in the Glossary of the Clay Minerals Society (CMS) Nomenclature Committee – Clay Science Project (www.clay.org; August 2011).

A tumour/neoplasm is caused by a purposeless multiplication of living cells. The word neoplasm means new growth. Tumours are common in carnivore as compared to other animals. Horse and cattle are mostly affected than sheep, pig and goats. Old animals are affected more commonly than young ones. Cancer, according to current opinion, is a multitude of different diseases and is no more a “one diseases’. Myriads of tumour types and plethora of their patho-physiology in different species necessitates species wise study of tumours in detail.  Of all species, dog develops cancer twice as frequently as humans. Mammary tumours rank second (behind skin tumours) as the most common neoplasm in dogs and constituting more than 50% tumours in bitches.

Soil is inhabited by incredibly diverse living microorganisms that are significant to plant growth and development. Soil microorganisms produce a variety of metabolites, probably several thousands, which influence the plant growth either positively or negatively. Therefore, in such a complex situation, identification of any one metabolite or a compound as active phytohormone or phytotoxin is really an uphill task. Appropriate extraction procedure, knowledge about the proper site for its action, appropriate conducive physiological environment and the effective intensity or concentration is of prime importance. Compounds, in general, are inhibitory to growth at higher concentrations but usually stimulatory at lower concentrations. All growth regulators, irrespective of their provenance or structure, may be divided into two groups.

2.1. Introduction

A system of housing is more or less synonymous to the system of management of dairy cattle. Housing is essential to protect the animals from extreme climatic conditions, wild animals and theft. Housing also helps to maintain normal health of the animal by proper feeding, watering and reducing environmental stresses. An efficient housing system ultimately leads to an efficient management and reduce labour requirements to the minimum.

3.1. Introduction 

Calves are the future replacement stock of dairy farm. The raising of calves, an important operation of the dairy farm requires a great deal of managemental skill, application and constant attention. Any negligency results in increased calf mortality, poor growth and development of the calves. So, care of the calves is important for success of the dairy farm.

12.1. Introduction

Milking is the crucial operation in a dairy farm, as milk is the main source of revenue of a dairy farm. Milking is a labour intensive operation. About 50-60 percent of the total time of farm operation is required for milking and allied activities. Milking is an art which requires skill, patience, efficiency and experience. It should be handled quietly, quickly, gently, cleanly and completely, by avoiding any type of pain, annoyance or inconvenience to the animals. Possession of high yielding animals or good managemental conditions will not generate profit if the milking operation is inefficient.

21.1 Introduction

Plants and insects share a wonderful relationship. Both are dependent on each other at different levels and chemicals emitted by plants connect them to a large extent.  “Plants” contribute to a major share of occupancy on earth and makes several organisms such as insects & microbes and also humans to depend on them for their survival. This dependency leading to several interesting interactions between plants & insects which are often utilized by humans for their own benefit. Plants maintain incredible communication with their associated organisms. Since plants are rich banks of chemicals and constantly emit them in to its immediate environment which contributes in communication between insects and plants. Insects are the major organisms that have a long relation with the plants and there are several incredible ways how plants can interact with insect species.

23.1 Introduction

Cultural methods have been in practice for pest management in traditional systems of agriculture since time immemorial. The worldwide awareness of safe environment provided the impetus to foster non-chemical pest management strategies. Of these strategies, cultural control constitutes the most farmer-oriented approach, where the weak points in the biology and behaviour of insects are exploited and pressure is exerted on the population by manipulating the environment.  In addition to the cultural practices, the other widely used approach is the use of physical control methods which hold promise and provide an attractive alternative to current practices, particularly when integrated into a general control scheme incorporating cultural methods, plant breeding, biological or behavioural methods and pesticides. In physical control methods, the physical environment of the pest is modified in such a way that the insects no longer pose a threat to the agricultural crop.

INTRODUCTION

Food is the basic need of human beings. It gets spoiled primarily due to microorganisms and enzymes. Energy is required for microbial growth and enzymatic reactions. At low temperature, the rate of biochemical reactions is slow resulting in prolonged storage life of food. It must have been observed long back that food could be stored for longer period without deterioration during the winter months. Since then this principle is being used to extend the storage life of foods. A sea change can be observed in development of low temperature preservation technology. It has travelled a long journey to reach this stage; however, a major break through took place in twentieth century. Low temperature technology is of two types; refrigeration and freezing. In refrigeration storage, water is in liquid phase and temperature is maintained above freezing point. In freezing technology, the food is stored below freezing point and water gets converted into ice. The former is short term preservation due to slow growth of microbes and lower enzymatic activity while the later is long time preservation due to inactivation of enzymes during blanching and inhibition of microbial activity due to unavailability of free water and much lower temperature. Low temperature preservation is widely accepted and is of commercially important in food supply chain.

E numbers : Each food additive used in the food industry has been given a specific number code for their identification. These numbers are called as E numbers. These E numbers are used within the European Union. The word prefix “E” stands for Europe. They are commonly used on the food label through out the European Union. These are not used in Australia and New Zealand. The different food additives are given different E numbers depending upon the type of food additive like E100-E199 (food colours), E200-E299 (preservative), E300-E399 (antioxidants), E400-E499 (thickners, stabilizers, emulsifier), E500-E599 (pH regulator, anticaking agent), E600- E699 (flavour enhancers), E700-E799 (antibiotics), E900-E999 (miscellaneous like waxes, synthetic glazes, packaging gases, sweetners, foaming agents), and E1000-E1099 (additional chemicals).

HACCP : The Hazard Analysis and Critical Control Points (HACCP) is a scientific, rational and systematic approach to identify, assess and control hazards during production, processing, manufacturing and use of food. It ensures safety of the food. HACCP presents a good opportunity for the food industry for upgrading quality and bringing uniformity and consistency in their supplies to international market. or It is a systematic preventive approach to food safety that addresses physical, chemical and biological hazards as a mean of prevention rather than finished product inspection. It involves identification, evaluation and control of hazards which are significant for food safety.

Abstract

With categories including food, building materials, medicinal plants and resins, non-wood forest products are the economically important face of biodiversity. Using non-wood forest products to generate income and alleviate poverty requires different approaches to their special characteristics. Among the features that distinguish non-wood forest products from other goods are the unpredictability of the quantities available, the lack of control of collectors over their growth conditions, and the difficulty of ensuring that the products can be placed on the market efficiently. In developed countries such as Finland, with under-harvesting of non-wood forest products, getting an economic benefit from these involves the seasonal migration of collectors. The latter is illustrated by the case of Thai in a working visit to Finland, to pick the often underutilized wild berry harvest in Lapland. The majority of the workers are from farming backgrounds, but there is a weak positive correlation between their non-wood forest product activity in Thailand and berry picking in Finland.

Abstract

Mahua (Madhuca spp.) is an important tree in India, with high socio-economic, environmental and spiritual values. We carried out this study among the local communities of Azamgarh district (eastern Uttar Pradesh) and with the Gond and Baiga tribes from Raisen and Dindori districts, Madhya Pradesh. Among the five mahua species found in Indian subcontinent, Madhuca latifolia is widely distributed in the north and central plains, the focal area of our study. Mahua has been vital to the survival of these communities, particularly the Gond and Baiga tribes, from the time immemorial. It has been a major source of food energy in the form of sugar, seed oil and alcohol. As well, different parts of the tree are used as ethnomedicine. The tribal people’s high regard for mahua is reflected by its sustainable and regulated use. In this study, we present an in-depth analysis of conservation, management and sustainable use of mahua, and also suggest its role in socio-economic adaptation, with particular reference to climate change.

Tremendous genetic diversity occur within different crops of this family with respect to their adaptability. Some cucurbits are grown in tropical, subtropical or arid deserts whereas other prefer to grow in temperate conditions. Harvested fruits and vegetables can be potentially exposed to numerous abiotic stresses during production, handling, storage and distribution (Hodges, 2003). However, when the abiotic stress is moderate or severe, quality losses almost always are incurred at market (Toivonen, 2003). Annually about 42% of the crop productivity is lost owing to various abiotic stress factors (Oerke et al., 1994). One of the key factors for abiotic stress in crop plants is the ill effect of global warming which may cause reduced precipitation, less snow pack, and earlier snow melt, leading to drought conditions. In addition about 20% of the world’s irrigated lands are affected by salinity (Zhu, 2001), a situation worsened by climate changes.

Introduction

Vegetables are the vital sources of minerals, vitamins and dietary fibres and play an important role in supplying nutrition to human health. Vegetables require comparatively lesser quantities of agro-inputs to grow. Vegetables are rich source of vitamins, minerals and plant fibres which provide food and nutritional security. These also generate high income and employment, particularly for small farmers. Vegetables being a rich and cheap source of vitamins and minerals, occupy an important place in the food basket of Indian consumers, a majority of whom are vegetarian. This persistent vegetarianism coupled with rising per capita income is fuelling a rapid growth in consumption of vegetables. Presently, India is producing more then 70 types of vegetables which are capable of meet out the economic and nutritional requirement of the country (Table 1). There has been a revolution in the production of vegetables in the country in the last four decades.

Introduction

Vegetable crops are an important component of Indian Agriculture. They are known for their short cycle and high productivity per unit area providing a valuable source of income leading to improve livelihood. The prosperity and advancement of a nation largely depend on achieving nutritional security to its people. The vegetables play a vital role as major supplement to food and nutritional security of our people. They are important source of nutrients like b- carotene, vitamin B, C, E as well as folic acid, iron, magnesium, etc. and they also supply fair amounts of carbohydrate, protein, fiber, antioxidants and energy.

Introduction

Green house is a structure in which external climatic factors can be controlled for cultivation and protection of crops. It has mainly two parts. (a)  a frame or the basic structure and (b) the cladding or covering material (U.V. film) Frame can be made of G.I. pipes, bamboos, woods or iron rods while the cover can be of glass or plastic films. In India the technology is primarily used. Greenhouse technology is more suited to vegetables crops (such as tomato, cauliflower, capsicum, cucumber, leafy vegetables etc.), and flowers (like rose, gerbera, carnation, etc).  This technology is mainly suitable for commercial farming, as it requires investment in setting up the entire framework.  Based on cooling systems of the greenhouse, it can be classified as naturally ventilated and fan-pad type greenhouse.

Introduction

Plant hormones (also known as phytohormones) are chemicals that regulate plant growth, which are termed ‘plant growth substances’. Plant hormones are signal molecules produced within the plant and occur in extremely low concentrations. Plant hormones are small, simple molecules of diverse chemical composition: indole compounds, terpenes, adenine derivatives, steroids, aliphatic hydrocarbons and derivatives of carotenoids or fatty acids. In the context of rooted habit and iterative mode of growth, plant hormones are not produced in specialized glands, but in most parts of the plants. Plant hormones are required in minicule quantities and their concentrations at sites of activity are precisely regulated. Changes in hormones concentration and tissue sensitivity mediate a whole range of development processes in plants, many of which involve interaction with environmental factors. First five hormones discovered from the plants were gibberellins, abscisic acid, cytokinins, indole-3-acetiv acid, and ethylene as well as some compound shown more recently to have a regulatory role in plant development, namely, brassinosteroids, polyamines, jasmonic acid and salicylic acid.

Introduction

Integrated disease management in horticultural crops are of paramount importance these days, keeping in view that a single management practice cannot control multiple diseases in a particular agro ecological system. It is therefore worthwhile that all management practices are integration of cultural, physical, biological and chemical control strategies. The routine application of fungicides for insurance purposes is not appropriate, as it does not focus the proper attention on the real problem and can lead to resistance and potential environmental issues. Fungal, bacterial, viral diseases cause a great damage to the horticultural crops thus resulting in economic losses to the farmers. The extent of damage varies from year to year, location wise and variety involved. The pathogens responsible for causing diseases affect the crop at various stages of their development right from seedling stage to harvest. The manifestation of a disease can be in the form of different symptoms viz., damping off, leaf spot, blight, wilt, etc. It is thus important to properly identify a particular disease in a crop on knowledgeable basis to reach a particular end of profitability. As such, a proper disease diagnosis is of paramount importance.

Introduction

Insect pests cause enormous loss to horticultural crops through direct and indirect invasion on various plant parts. It is estimated from the available information in the literature that there are about 1000 insect pests species on about 100 major and minor horticultural crops in India (Sharma et al., 2011).  The yield and quality of produce are central system point to the sustainable horticultural production. If not properly managed, pests can dramatically reduce crop yield, quality and subsequent returns. We invest a lot of time, money and natural resources into growing horticultural crops. Good pest management could protect this investment from avoidable losses.

Introduction

India has very old and long tradition of flower cultivation. With changing life styles and increased urban affluence, floriculture has assumed a definite commercial status in recent times. Improved communication facilities have increased their availability in every part of the country. Floriculture in India is being viewed as a rapidly growing industry. In India, at present total area under flower crops is about 2,33,000 ha with production of about 17.29 lakh tonnes of loose flowers and 76732 lakh  number of cut flowers (NHB database, 2013).The important floricultural crops in the international flower trade are rose, carnation, chrysanthemum, gerbera, gladious, gypsophila, liastris, bird of paradise, orchids, anthurium, tulip, lilies, etc. All the flowers and ornamentals are the most perishable commodities needs special care during harvesting, handling, storage and transport. The losses can be both, quantitative as well as qualitative, which result in loss in terms of monitory value.

Meaning of Advertising

According to Concise Oxford Dictionary, the word to advertise means to make generally or publicly with a view to increasing sales. The word ‘advertising’ is derived from the Latin word ‘advertese’ which means ‘to turn (the mind) to’. Advertising means providing adequate knowledge about some special product/service/idea to potential consumers so that they are stimulated to buy it. Adequate knowledge about a product means to let people know the name of the product, its function, size, price and place of its availability. The organizations providing service or idea give information regarding where, how and on what conditions their service or idea can be made available and how the same can be helpful to the people. Today is the age of competition. Consumers buy commodities after careful consideration. Under the circumstances, manufacturers are faced with the problem of how to motivate the consumers to buy their product. To find a solution to this problem, manufacturers make use of advertising.

1. Feminization of Agriculture

Almost all active women in rural India can be considered as ‘farmers’, in some sense – working as agricultural labourer, unpaid workers in the family farm enterprise, or combination of the two. Moreover, several farm activities traditionally carried out by men are also being undertaken by women as men are pulled away into higher paying employment. Thus rural India is witnessing a process which could be described as ‘feminization of agriculture’. The significantly high and growing population of female headed households has also highlighted women’s contribution to agriculture.

Since time immemorial, women have played and continued to play a key role in conservation of basic life support system, such as, land, water, flora and fauna. Women power at present constitutes nearly half of the global population and account one third of the total work force. They contribute more than half of duties and responsibilities but are not given proper rights. In India till now rural women continue to struggle with dual responsibilities of economic production and domestic labour, and most are confronted by poverty, illiteracy, high health risks, inadequate access to productive resources, and lack of credit/market access. The empowerment and autonomy of women and the improvement of women’s social, political, legal and economic status is essential for sustainable rural development

1.0 INTRODUCTION

The cumin (Cuminum cyminum Linn.) belonging to family Apiaceace is an important seed spice believed to be indigenous to northern Egypt, East Mediterranean region, Iran, Turkey  and India (Amin, 2003; Raghavan, 2007). It is popularly known as safed jeera and is one of the most common spices of daily use in the Indian sub-continent. Cumin is well known to ancient civilization. It is one of the oldest spices known since biblical times, valued mostly for their digestive properties and for flaovouring bread and other dishes during the periods of ceremonial fasting. As early as 5000 BC, Egyptians preserved the bodies of their kings by mummifying them with cumin, anise and marjoram.

In this era of computer, mathematical models become integral part of hydrologic studies due to advancement in soft technology. But question always arises as ‘Why should modeling?’ It was well expressed by Rosenblueth and Wiener (1945) as

No substantial part of the universe is so simple that it can be grasped and controlled without abstraction. Abstraction consists in replacing the parts of the universe under consideration by a model of similar but simpler structure. Models, formal or intellectual on the one hand, or material on the other are thus a central necessity of scientific procedure.

Moringa oleifera Linn. belongs to the family Moringaceae, that consists of only one genus with about 13 species of deciduous trees (Keay, 1989). It is believed to be the native of India-Pakistan-Nepal borders, but now is becoming widely distributed and grown in several countries, particularly in tropical and subtropical regions (Satti et al., 2013). Besides some other species, M. oleifera is recently being the most widely cultivated in numerous countries in Asia, including the Arabian Peninsula, central and south America and in most African countries like Benin, Burkina Faso, Cameron, Senegal, Mauritania, Niger, Nigeria, Tanzania, Uganda, Kenya and Sudan (Nasir and Ali, 1972; Ramachandran et al., 1980 and Parrotta, 2001).

Delicious and crunchy apple fruit is one of the most popular fruit favoured by health conscious, fitness freaks who believe in “health is wealth”. It is one of the popular wonderful fruit that contains a long list of essential nutrients that in the true sense are indispensable for human health. The antioxidants in apple have many health promoting and disease prevention properties; thus justifying the adage “An apple a day keeps the doctor away”. Apples help in controlling heart diseases, weight loss and cholesterol levels. Apples do not have any cholesterol instead they have fibre which reduces cholesterol by preventing reabsorption and thus are low in calories. Unpeeled apples provide plenty of nutrients which are present just under the skin. Apples are a good source of minerals like potassium, calcium, magnesium and iron, vitamins of B-complex such as riboflavin and pyridoxine (vitamin B6), vitamin C, folic acid and beta carotene. Apart from this they also contain appreciable quantities of tartaric acid that gives tart flavour to them.

Importance of nutrient management in crop production can be very well explained by conducting various field trails by different fertilizer nutrient, methods of application and sources of fertilizer. Experiments on nutrient management are being carried out to study the impact of nutrient application, new techniques of fertilizer application, sources and doses of fertilizers on plant growth, yield and soil fertility and their efficiency over existing one was elucidated through various efficiency indices. The following efficiencies are normally being used in nutrient management studies.

Agricultural water consumes about 85% of the available water. The future hopes to solve world’s food problem lies in irrigation development. Considering the need of efficient management of water, which is crucial at this point understanding of different efficiencies of the irrigation related experiments or projects, is necessary. Irrigation efficiency is used to evaluate how effectively the available water is used in crop production. Water is conveyed through canal system, watercourses and channels to crop fields. Irrigation is applied to store water in the effective root zone of soil for use of crops. A considerable loss occurs after its diversion from sources to its actual use by crops. The extent of water loss in the process decides the irrigation efficiency. Irrigation efficiency declines as the water loss increases. A high efficiency of an irrigation project is always desirable. The efficiency may be estimated for various operations beginning from diversion of water to its actual use by crops, uniformity in its distribution in the root zone, its use for crop productivity, economics and so on.

The rhizosphere is the narrow zone of soil surrounding the root that is under the immediate influence of the root system. This zone is rich in nutrients when compared with the bulk soil, due to the accumulation of a variety of organic compounds released from roots by exudation, secretion and deposition. Organic compounds released by plant roots include amino acids, fatty acids, nucleotides, organic acids, phenolics, plant growth regulators, putrescine, sterols, sugars and vitamins. Because these organic compounds can be used as carbon and energy source by microorganisms, microbial growth and activity is particularly intense in the rhizosphere.

Abstract
Better seed production technology is vital to furnish quality seed of improved varieties. Trees are generally propagated from seeds and the suitability and quality of the seeds have a big effect on the success of the plantations, afforestation and reforestation programmes raised from them. It must be stressed that good seed implies seed which is both of high viability and vigour and is genetically well suited to the site and to the purpose for which it is planted. The use of sound seed from stands of high inherent quality is widely recognized as the best means of ensuring fast-grown and healthy plantations capable of yielding high quality wood. Quantity, as well as quality, of seed production is important. Seed quality depends on factors like source, time and techniques of harvest, processing and storage practices. Unlike agriculture, the forestry seeds have great variation in size, shape, dormancy, viability, moisture content, etc.

Abstract

The availability of the quality seed is the first and the most important requirement which is of great relevance in tree improvement programme. Unlike agriculture, the forestry seeds have great variation in size, shape, dormancy, viability, moisture content, etc. It needs special techniques for collection, handling, processing and storage of the seeds of the large number of forest species. A strong commitment to improving tree seed technology is required for full utilization of seed supplies with the help of recent advances in seed physiology. Substantial improvements have occurred as a result of seed technology research offering the potential for major advances in traditional seed production and distribution systems.

A key question facing agricultural scientists in the 21^st century is how to produce sufficient amounts of food, feed and farm income while protecting and improving environmental quality (Robertson and Swinton, 2005). Intensive soil tillage, mismanagement of land, water and fertilizers had severe negative economic, environmental and social consequences (Foley et al., 2011; Godfray and Garnett, 2014; Tilman et al., 2011). Presently depletion and / or degradation of natural resources (land, water, and biodiversity), decreasing farm profitability, low input use efficiency (fertilizer, water, energy, pesticides, and labor), environmental pollution (soil, water, air), climate change and scarcity of farm labour are threatening the sustainability of crop production systems.

Introduction

Plants are often subjected to unfavorable environmental conditions – abiotic factors, causing abiotic stresses - that play a major role in determining productivity of crop yields but also the differential distribution of the plants species across different types of environment. Some examples of abiotic stresses that a plant may face include decreased water availability, extreme temperatures (heating or freezing), decreased availability of soil nutrients and/or excess of toxic ions, excess of light and increased hardiness of drying soil that hamper roots growth. The ability of plants to adapt and/or acclimate to different environments is directly or indirectly related with the plasticity and resilience of photosynthesis, in combination with other processes, determining plant growth and development, namely reproduction. A remarkable feature of plant adaptation to abiotic stresses is the activation of multiple responses involving complex gene interactions and crosstalk with many molecular pathways.

Date palm (Phoenix dactylifera L. Family-Palmaceae) also known as Khajoor or Kharek is an ancient important fruit tree of semi-arid and arid regions of the world. It grows well under poor desertic soils due to its hardy plant characteristics and deep root system. It is also one of the most suitable fruit trees, which can be easily grown under saline conditions. Date palm grows as much as one feet per year, and as high as 80-100 feet under favorable environment. It is well known fact for date palm that its feet in the water and its head in sun. It requires dry hot climate for growth and development of fruits. In arid region, crop production is risky preposition, where date palm cultivation contributes in achieving food security, high nutritive value food, crop diversification, desertification control, income generation and foreign exchange earnings. It can be grown at such places, where adequate irrigation facility is available; besides, other climatic requirements (Chandra et al, 1992, Singh et al, 2007). The date tree has religious significance. The fruits are used during holy month of Ramzan by Muslim peoples. As Saudi Arabia is principal producer of date palm in the world, the palm tree is incorporated in the national emblem of Saudi Arabia to represent vitality and growth

Introduction

The concept of database is the approach to information organization in computer-based data processing. (Date, 1995 and Everest, 1986).

A Geographic Information System is as good as the data contained in it. Accurate and efficiently organized data are critical to the durability of the system. Data collection, capture and organization will occupy much of the time in building a GIS solution. The analysis potential of a GIS will depend on the database. It is essential to understand database concepts to practice GIS. It is erroneous to view these GIS databases as mere stores of information. The database is used to abstract very specific sorts of information about reality and organize it in a way that will prove useful during subsequent analysis. The database should be viewed as a representation or model of the world developed for a very specific application.

Conversion of real world geographical variation into discrete objects is done through data models. They represent the linkage between the real world domain of geographic data and computer representation of these features. Data models discussed here are for representing the spatial information.

Minimum field standards for seed production have been prescribed  for each crop. The major components to be looked into for meeting the field standards are: 
   Preceding crops 
   Isolation distance 
   Number of field inspections 

The minimum proceding crop requirement has been specified to minimize genetic contamination on account of volunteer plants germinating from the left over seeds in the previous season. The disease contamination is also possible from soil borne disease organisms if the previous crop was not certified. The preceding crop requirement would mean that for a prescribed minimum period the same crop or any other contaminating crop should not have been grown on the same field where seed production is to be taken up unless the preceding crop was a seed crop and had met the field/the seed standards.

The genetically engineered (GE) seeds developed using recombinant DNA technology often referred to as transgenics or genetically modified organism (GMOs) provide an usually adaptable, scale neutral technology for the farmers. Even small farmers can benefit from such seeds provided the seeds are made available at reasonable cost. While growing such seeds the existing crop management practices are usually sufficient. The transgenics or GMOs are also defined as those organisms with a gene or gene construct of interest that has been introduced by molecular or recombinant DNA techniques. These exclude organisms produced by conventional breeding as well as organism produced by rearrangement of genetic materials by physical methods or by chemical means. Thus, GMO’s carry trangene(s) which when integrated and expressed stably and properly, confer either a new trait to the organism which was hitherto not present (such as insect resistance), or enhance an already existing trait such as nutritional quality (Prasana 2001).
