Introduction

Development of feeding strategies that are more efficient and more eco-friendly by reducing waste is one of the key priorities in poultry production today. Thus, there is a focus on reduction of the crude protein content in a diet fortified with adequate amounts of currently available free amino acids (e.g. L-Lys, DL-Met, L-Thr, L-Val and L-Trp) in order to optimize protein utilization efficiency while maintaining production performance and reducing nitrogen excretion in chicken. Baker et al (1978) reported that animals do not need dietary protein to provide amino acids. Since, then numerous studies have been conducted to study amino acid requirement of poultry. They are components of tissue proteins and provision at insufficient levels leads to reduced protein synthesis. Provision of the different essential amino acids is therefore a prerequisite for maintaining optimal rates of protein synthesis. However, optimizing amino acid nutrition requires consideration of the different functions of amino acids, which are recognized to have several significant influences. Amino acids are precursors of important molecules.

Introduction

Minerals are essentially required for growth maintenance, egg and meat production, health, nutrient metabolism, physiological function, reproduction, skeletal growth and development and maintenance of normal immune function. There are 25 essential minerals, seven are major minerals, as they are present in relatively higher amount in the body than the trace minerals and need to be supplemented in higher quantities in the feed. These major minerals are calcium, phosphorus, magnesium, sodium, chloride, potassium, and sulphur. The micro minerals are present in small quantities in the body and their requirements in the diet are below 100 mg/kg. The 18 trace minerals are iron, copper, zinc, manganese, iodine, selenium, cobalt, molybdenum, chromium, tin, vanadium, fluorine, silicon, nickel, arsenic, aluminium, lead and rubidium. Among these, the first nine micro minerals have been identified to play a significant role in birds. Total minerals in diet include feed sources and supplementary sources. 

After the Second World War, the 1940’s and 1950’s was the wide spread establishment of artificial insemination and the introduction of frozen semen in cattle breeding.  In the late 1960s came revolution in measurement of hormones in the body fluid with the introduction of sensitive radio-immuno-assay (RIA) techniques, which provided a new approach to early pregnancy diagnosis, emerging around the same time were early forms of the ultrasonic which could also employed in the detection of pregnancy. The 1970’s were to see embryo transfer and freezing of embryos in cattle becoming commercial realities and their incorporation into increasingly effective breeding improvement programme with the availability of prostaglandins (PGs) and Gonadotrophin releasing hormones (GnRH) that decade also witnessed new possibilities for estrum control in cattle and horses.  Few years later came the ability to produce the cattle embryos in the laboratories in large numbers and at low cost.

Water is the most critical component of life system. Irrigation plays vital role in rising and stabilizing yield and maintaining quality of fruit crops grown in tropical or sub-tropical climate. Micro irrigation is one of the modern and advanced methods of irrigation which is becoming popular in areas having problems like water scarcity and poor quality of water. Since the competition for water between agricultural and non-agricultural sector is increasing day by day, the efficient management of water resources is very essential to meet the water requirement. It is anticipated to reduce water use for agriculture by 70% in the coming decade, where the present day share is 80%. Demand for water is increasing in non-agricultural sectors like industry, energy, domestic use etc. Hence, policy makers and researchers consider water as the main obstacle for growing enough food crops in the coming years. In India where population is increasing at alarming rate, the area under irrigation should go up from 60 million hectares to 114 million hectares by the year 2050. In this context, micro irrigation plays a major role under limiter water agro ecosystem.

Introduction

India is a rich center of plant diversity due to varied climatic conditions as well as soil qualities which provide a better platform for the diverse plant groups. In India around 45000 plant species are spread over the area (Mayers, 1988). These plant species multiply and produces the new plant. The multiplication of plants is termed as propagation and the art of propagation is as old as civilization of human being. The history of civilization began with the propagation and growing of plants. Plant propagation was in practice in pre-historic period. However, the propagation process has got commercial popularity only recently. The success in plant propagation depends on a thorough knowledge of the growth of plants, choice of suitable method and technical skill. In nature, plants multiply naturally to perpetuate themselves. Now-a-days, propagation practices have been totally modernized and became advanced from field to in vitro. Variation in plant propagation can be observed in the nature like some plants are producing many seeds for future generation with their unique type of dispersal mechanism. Among a large

Introduction : Need to Change

During the era of Green Revolution, India remarkably achieved self-sufficiency in food production with the introduction of high-yielding varieties, extension in the irrigated cultivable land, high use of chemical fertilizer such as Urea and other sources of NPK fertilizers and increase in cropping intensity.During these processes, relative contribution of organic manures as a source of plant nutrients declined substantially. Due to heavy application of chemical pesticides an increase in resistance of insect pests has also been noticed for most of the regular used plant protection chemicals. Health hazards associated with intensive modern agriculture, such as pesticides residues in food products and groundwater contamination are matter of concern. In the progress of green revolution technologies and chemical dependent nutrient management has declined the overall productive capacity of the soil due to no judicious fertilizer use. Such concerns and problems faced by modern-day agriculture gave birth to new concepts in farming, such as organic farming, natural farming, biodynamic agriculture, donothing agriculture, eco-farming, etc. The essential feature of such farming practices imply, i.e., back to nature.

1. Introduction
The era of genome sequencing was exploded by the upcoming of Human Genome Project (1989), coordinated by the U.S. Department of Energy and the National Institute of Health to identify all the approximately 20,000-25,000 genes, 3 billion chemical base pairs, store this information in databases, improve the tools for data analysis, transfer related technologies to the private sector, and address the ethical, legal, and social issues (ELSI) that may arise from the project. The dawn of genome sequencing began with Fredric Sanger’s sequencing almost twenty-five years ago. The time consuming and labor intensive gel preparation and their running, as well as the cost of such experiments replaced the conventional sequencing by “shotgun” sequencing.

Introduction

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

Introduction

There has been a slow evolution of information technologies in fruit crop production as innovators combined their prior field experience with an attitude of learning by doing while looking for practical applications for farm management. As a suite of technologies became available for use in agriculture production, a new management strategy that combined information with decision making became known as Precision farming. Precision farming is the emerging technology which involves maintaining of crop inputs on site specific basis with reducing waste, increasing the profits and maintaining the quality of environment. The main tools involved in this are Geographical Information System (GIS), Variable Rate Technology (VRT), Global Positioning System (GPS), Yield Monitoring and Remote Sensing.

Abstract

Horticulture crops play significant role in improving the productivity of land, generating employment, enhancing exports, improving economic conditions of the farmers and entrepreneurs and providing food and nutritional security to the people. For better management of the existing crops and to bring more area under horticulture crops, updated and accurate database is necessary for systematic planning and decision making. Remote sensing (RS) is an advanced tool that aids in gathering and updating information to develop scientific management plans. Many types of sensors namely microwave radiometers, laser meters, magnetic sensors and cameras collect electromagnetic information to derive accurate, large-scale information about the Earth’s surface and atmosphere. Because these data and images are digital, they can easily be quantified and manipulated using computers. RS can be used in efforts to reduce the risk and minimize damage. The same data can be analyzed in different ways for different applications. A number of studies were aiming at identification of crop, area estimation, disease and pest identification, etc. using satellite data in horticulture. The potential use of RS techniques in Horticulture is briefly reviewed in orde

Introduction 

Conservation tillage has been defined based on percent cover of the soil surface with crop residue (CTIC, 2000). Quantifying crop residue cover on the soil surface is important for improving estimates of surface energy balance, net primary productivity, nutrient cycling, and carbon sequestration. Quantifying crop residue cover is also an important factor in controlling soil erosion and evaluating the effectiveness of conservation tillage practices (Barnes et al., 2003). Collecting this information by conventional method of survey and line transact are time-consuming, labor intensive, costly and can involve destructive sampling (Morrison et al., 1993). Moreover, field data are limited because they provide point, rather than area information. Remote sensing technique revealed as promising tool in providing such spatial data over a large area in a time and cost-effective manner.

Introduction

In India, Fruits and vegetables comprises nearly 90% of the total horticulture production. India is now the second largest producer of fruits and vegetables in the world and leader in several horticultural crops, namely mango, banana, papaya, cashewnut, arecanut, potato, and okra (National Horticulture Board, 2015). The total area occupied by horticultural crops in India was 23.69  million ha and total production was 283 million tonnes in 2015-16 (Source: Ministry of Agriculture and Farmers’ Welfare). Different horticultural crops like fruits, vegetables, spices, medicinal plants and plantation crops comprises a large chunk of the total crop sales value of the country and also secures nutritional security of the persons of the country. For systematic and efficient management of existing crops and to bring more area of the country under the cultivation of horticultural crops to increase overall horticultural production in term of time and area, a database must be created for decision making and planning. 

Production is based on reproduction and health of reproductive system. Economy of livestock industry is directly attached to the maintenance of high fertility in the herd so controlling the reproductive diseases in cattle is a must.  Reproductive health may be disturbed by reproductive infections like Brucellosis, Leptospirosis, Infectious bovine rhinotracheitis and Bovine viral diarrhea.

The  information on normal reproductive traits in domestic animals like calving interval, age at first calving etc, is essential for getting the maximal reproductive efficiency of the animal by the farmer. It also helps in improving the reproductive efficiency of the animals by different required means viz nutrient/mineral supplementation, antibiotic, hormonal therapy etc.

Introduction

The Indo-Gangetic plain (IGP) is of great importance for the food security of India. It extends over 1,600 km with a width of 320 km, including the arid and semi arid environments in Rajasthan and Punjab and the humid and per humid deltaic plains in west Bengal (Shankaranarayana, 1982). During the green revolution period in the early 1960s, production increased through area expansion and intensification of the rice –wheat system. Driving forces included suitable thermal regimes for rice and wheat cultivation, development of short- duration, nitrogen responsive cultivars, expansion of irrigation and an ever increasing demand for food from the rising population. The rice –wheat system, covering an area of around 10 million hectares (mha), is the major cropping system in the IGP. These two crops together contribute more than 70 % of total cereals production in India from an area of around 25 mha under wheat and about 40 mha under rice. The small states of Punjab and Haryana contribute 20 % of the total national grain production and 50 % and 85 % of the government procurement of rice and wheat, respectively (Singh, 2000).

Conservation agriculture (CA) refers to a set of agricultural practices involving three basic principles of proven scientific soundness. These include continuous minimum mechanical soil disturbance; permanent organic soil cover with crop residues or cover crops; and diversified, efficient, economically viable, appropriate spatial and temporal crop sequences providing opportunities for saving on inputs (labor, fuel, machinery etc.), improving resource use efficiency (water, nutrient, energy etc.) and mitigating GHGs emission with climate change adaptation. Recently research efforts have been made to refine the crop management technologies which are more resource efficient, improve production and income, and reduce GHGs emission compared to the conventional practices. Resource conserving technologies (RCTs) are increasingly being adopted by farmers in the rice-wheat belt of the Indo-Gangetic Plains because of advantages of saving on labor, water, fuel and cost along with timeliness in operations particularly early planting of wheat.

Introduction

The subject of conservation agriculture CA has emerged as a need given the declining productivity of land and increasing costs of input that is putting tremendous pressure on the farming community. Higher yield expectation from land given also brings pressure to the subject of food security. Considering the markets with the globalisation influence is beyond a farmer’s means of influence and price realisation is not a point of control, the situation has deteriorated to their disadvantage. Climate change and soil degradation on the other hand is a reality and agriculture is both a sufferer and contributor, and cannot ignore this reality. Good physical management of soils is one of the key factors to maintain or improve agricultural productivity, in tropical and subtropical regions, and to reduce soil and environmental degradation (Lal, 2000). Tropical soils often have a stable structure and are well aggregated but management practices like intensive ploughing or avoiding the use of cover crops can lead to rapid deterioration (Madari et al., 2005).

Introduction

Rice is grown 43.7 m ha land in India. It is cultivated in 39.51 m ha under kharif and 4.26 m ha under rabi season. As a whole, rice production in India was 104.32 m t (2011-12) with an average productivity of around 2.6 t ha-1. Majority of rice grown in India in the eastern part of the country comprises the states of West Bengal, Orissa, Chattisgarh, Assam, Bihar and Jharkhand. Maximum area under rice in eastern India in West Bengal (5.94 m ha) with a production of 15.04 mt. Productivity was maximum in West Bengal followed by Jharkhand, Assam, Bihar, Orissa and Chattisgarh (DOSE, MOA, GOA, 2011). There is a plenty of scope to increase the productivity of these region with proper policies and technological interventions. Rice area in eastern region (23.4 m ha) would be divided in different ecologies, namely, irrigated (23.2%), rainfed upland (17.9%), rainfed lowland (43.1%) and flood prone areas (25.1%).

Climate change is a statistical variation in properties of the climate system that includes changes in global temperature, precipitation, etc due to natural or human drivers over a long period of time. It may affect distribution and quality of natural resources thereby influencing livelihood security of the people (Status of Indian Agriculture, 2013). Recent climate change activities is the increase in earth’s temperature by 0.74^ºC between 1906 to 2005 (IPCC 2007) due to increase in anthropogenic emissions of green house gases such as carbon dioxide (CO₂), methane (CH₄), ozone (O₃), nitrous oxide (N₂O) and chlorofluorocarbon (CFCs). Increase in concentration of green house gases influence future climate as well as agriculture (Mall et al., 2006; IPCC, 2001; Aggarwal, 2003: Bhatia et al., 2004). For Indian region under South Asia, Intergovernmental Panel on Climate Change (IPCC), 2007 projected a rise in temperature from 0.5-1.2^ºC by 2020, 0.88-3.16 oC by 2050, and 1.56 - 5.44^ºC by 2080. This may anticipate greater instability in agricultural production (Aggarwal, 2008). Beside this, climate change also affects the dynamics and frequency of extreme events like tropical cyclones, associated storm surges, and rainfall events. Low lying regions are more vulnerable to climate change as increase in temperature melt down the glaciers causing floods, submergence, and degradation of these regions. Therefore, there is a need for a ‘wake up call’ at this stage to aware farmers about the climate change, extreme weather events like hailstorm, heat and cold waves, drought, flash and river floods and landslides, and its affect on crop and agriculture, and strategies to overcome it.

1. Introduction

Pineapple (Ananas comosus) is a tropical fruit having good sensorial characteristics such as, mechanical properties, flavor, acidity/sweetness ratio, color; and nutritional. Pineapple is known to be a good source of vitamins such as vitamin C, vitamin B and antioxidants. The free radical scavenging activity of pineapple is found to be much higher than banana and is comparable to that of guava (Alothman et al., 2009). However, it is a perishable cash crop that grows in abundance in a short time. This necessitates protecting the perishable fruit against quality loss during storage and distribution.

Fruit leathers are an economic and convenient substitute for natural fruits with high nutritional components. Leathers are made by removing moisture from wet pulp until the desired cohesive “leathery” composition is obtained. Since it is light and low in moisture it has minimum storage problems and is economical to ship (Moyls, 1981). Therefore, making fruit leather from fresh fruits is an effective way to preserve fruits (Maskan et al., 2002). Furthermore, fruit leather has far fewer calories, less than 100 kcal per serving (Huang and Hsieh, 2005) and have a far greater nutritional value (e. g., especially in terms of energy, minerals, antioxidants and fiber) than the fresh fruits because all nutrients are concentrated. There are large numbers of fruit leather available in the market, such as mango leather, apricot fruit leather, grape leather, berry leather, kiwifruit leather, and jackfruit leather (Torres et al., 2015).

4.1. INTRODUCTION

Rice (Oryza sativa) is the major food crop in the world. Nearly 40% of the world population consumes rice as the major staple food. Most of the people, who depend on rice as primary food, live in the less developed countries.  Archeological evidence on rice in India dates back to 1500-1000 B.C. Since the dawn of civilization, rice has served humans as a life-giving cereal in the humid regions of Asia and, to a lesser extent, in West Africa. Introduction of rice into Europe and the America has led to its increased use in human diets. There are 42 rice producing countries throughout the world but China and India are major rice production centers. Rice is grown in wide range of agro-climatic conditions ranging from mountainous (Jammu) lands to low land delta areas (Sundarban), spanning an area from 53° latitude north to 35° south of the world but about 90% of the crop is grown and consumed in Asia. Rice provides fully 60% of the food intake in Southeast Asia and about 35% in East Asia and South Asia. The highest level of per capita rice consumption (130-180 kg per year, 55-80% of total caloric source) takes place in Bangladesh, Cambodia, Indonesia, Laos, Myanmar (Burma), Thailand, and Vietnam (Kenneth and Kriemhild, 2000). In many cultures of the world rice is the central part of people’s life and culture. Rice is an excellent food and is an excellent source of carbohydrates and energy.

Eastern India is frequently affected by weather hazards, such as drought, flood and heat wave. The region consists of Orissa, West Bengal, and Bihar. The coastal states of Orissa and West Bengal frequently face cyclones, while Bihar and eastern U.P. face cold wave. Due to unfavorable seasonal weather, crop productivity is poor. However, the recent change in climate induced by global warming has further threatened the agricultural productivity in the region. Rice is the principal crop of Eastern India and rice based cropping systems has long been practiced in the region. While rice-rice is the most dominant cropping system in Orissa and West Bengal, rice-wheat is in Bihar and eastern U.P. Besides, rice-groundnut occupies a considerable area in the region. It is now doubtful whether the resilience of these cropping systems would continue sustaining the productivity under the climate change. The major aim of the proposal was to identify suitable adaptation measures of crop production under projected climate change. Climate change is expected to alter precipitation pattern, increase temperature, change in humidity level and decrease sunshine. As a result it is like to influence right from land preparation to the harvest and post harvest process. Thus the project aim was to revisiting the existing package of practices of selected cropping systems by simulation modelling, deduce suitable adaptation measures and validate these by OTC experiments.

Introduction

The word ‘risk’ derives from the early Italian risicare, which means ‘to dare’. In this sense, risk is a choice rather than a fate (Bernstein, 1996).

It is an inherent trait in humans to take chances. We believe that even though the future is uncertain we can make calculated choices based on our knowledge of past occurrences and the outcomes will be skewed in our favour. 

Introduction

Among vertebrate pests such as birds and wild animals, Well-known rodents include mice, rats, squirrels, dogs, gerbils etc., are great importance. Among rodents, rat and mice come under class Mammalia. They are small mammals belonging to order Rodentia and under sub family Murinae in the Family Muridae. Rat and mice cause severe damage to various crops like sugarcane, rice, maize etc. both directly and indirectly by gnawing, spoilage, contamination and hoarding activities. Beside this, it is big problem in house, store godown, warehouse, urban cities and industries. Rats and mice have caused more human suffering and more economic damage than any other vertebrate pest. It is also known to introduce secondary pest like fleas, mites and ticks into premises cause additional problem.  Statisticians estimate that rats and mice destroy 20 per cent of the world’s food supply every year directly by feeding and indirectly through contamination. It has adapted to nearly all human environments. They live in granaries, fields, city sewers, attics, basements, street trees, on top of 30-story buildings, and inside subway tunnels. Rats may be also responsible for the spread of many diseases. Some of the more important diseases associated with rats are plague, murine typhus fever, rat bite fever, salmonella food poisoning, and trichinosis. Adult mice have a small, triangular head with a small nose and little delicate feet as compared to the body. The mouse ears are very large relative to their heads. Rat ears are smaller relative to their heads. Rats have thicker tails than mice.

Abstract: Agroforestry, is a sustainable land use system being practiced since long time through out the country. A diverse climatic, edaphic, and environmental conditions prevailing in the country has made it possible to practice different kinds of agroforestry systems. Karnataka state has four major agro-ecological regions and coffee agroforests are prevalent in the region of Western Ghats of Karnataka, which has tropical climate. With in Karnataka, Kodagu district has highest area under coffee agroforests with a total area of 1,00,079 hectares and is the largest producer of coffee in the country. The area under coffee agroforests is increasing at the cost of natural forested landscapes, which is considered as a looming threat to biological diversity. But, at the same time there are arguments that these coffee agroforests also supports high level of biological diversity. There are very few studies to justify this argument. With this background the present study is an attempt to enumerate the biological diversity of coffee based agroforests of Kodagu.

The importance of Plant Pathology has been realized over the years owing to number of crop failures in different parts of the world. Plant disease control is indispensable for qualitative production and to compete in global agricultural trade. There is great need of sensitization of our research in various aspects which shall guide the generation to come for managing plant diseases not only for enhancing crop production but also in facilitating trade by conserving the biodiversity and environment.

Research Trend in Plant Pathology

Like in other sciences, there has been a change in the trend of research in Plant Pathology with passage of time. Up to the late 1960s most of the interest in plant pathology was concentrated in crop diseases mostly caused by fungi. Physiology of microorganisms and physiology of parasitism became increasingly popular fields of interest in 1960s.

Introduction

Climate is one of the main determinants of agricultural production. Throughout the world there is significant concern about the effects of climate change and its variability on agricultural production. Researchers and administrators are concerned with the potential damages and benefits that may arise in future from climate change impacts on agriculture, since these will affect domestic and international policies, trading pattern, resource use and food security. The climate change is any change in climate over time that is attributed directly or indirectly to human activity that alters the composition of the global atmosphere in addition to natural climate variability observed over comparable time periods (IPCC, 2007).

Introduction

In order to define climate it is important to distinguish it from weather. The weather that we experience on a day-to-day basis is a momentary atmospheric state characterized by temperature, precipitation, wind, and so on, and seems to vary in an irregular way, not following any particular pattern. Climate is a very general term that has a variety of closely related meanings. Usually, climate refers to the average weather conditions observed over a long period of time for a given area. In contrast to the instantaneous conditions described by weather, the timescale upon which climate statistics are calculated is typically thirty years. There can be variations in climate from year to year, or one decade to another, one century to another, or any longer time scale. The climate of a region depends on many factors including the amount of sunlight it receives, its height above sea level, the shape of the land, distance from the equator and how close it is to oceans. Generally speaking, the climate remains stable over long periods of time if the various elements within the system remain stable. However, if one or more of the components of the system is altered, the stability of the whole system is compromised and can lead to uncharacteristic behaviour and give rise to weather, which is outside the usual range of expectations. This situation can be described as climate change.

Introduction

Natural phenomena such as solar radiation, volcanic activity and ocean circulation influence climate and contribute to its variability. Evidence suggests that climate is now also changing as a result of human activities, such as the emission of greenhouse gases and changing land uses. The fourth assessment report of the Intergovernmental Panel on Climate Change (IPCC, 2007) concluded that the global average mean temperature and the frequency of hot extremes, heat waves, and heavy precipitation will very likely increase in response to increased concentrations of greenhouse gases in the atmosphere.

Society will have to make decisions in the coming years about how to adapt to a changing climate. Climate variability and climate change create risks to all sectors of the economy. Climate is already a prime factor in 9 out of 10 disasters, many of which cost billions of dollars and thousands of lives. Effective preparation for the possible effects of climate change requires the engagement of resource managers, planners, public works officials, local managers, community development specialists, businesses, residents, and property owners. The challenge is to provide these diverse stakeholders with trusted, useful, science-based information so that they in turn can make informed decisions. 

Introduction

Development, refinement and adoption of machinery for a range of soil and cropping situations will be fundamental in any success to promote conservation agriculture systems. This chapter reports on the performance of machinery for minimum/zero tillage, bed cultivation system and crop residues management in different cropping system and outlines the need for continuing efforts. Particularly, the focus will be on developing equipments/implements for fixed path / controlled traffic to minimize the ill effects of wheels in the longer terms.

Introduction

The wide range of agro-climatic and agro-ecological situations that prevail in the country supports cultivation of a variety of horticultural crops. The horticultural sector in the country is experiencing a phenomenal growth as far as increase in area, production and productivity are concerned. However, there is a lot of opportunities for enhancing productivity, post- harvest processing, value addition, hi-tech horticulture and precision farming etc. Hence, it will be enterprising to develop this sector, especially among the marginal and small farmers, so that that it will help them doubling their income from farm sector. 

Abstract 

The district Murshidabad lies within the Younger Deltaic Plain and the Bhagirathi Recent Surface has been considered as the severe flood affected district of West Bengal state, India. Murshidabad is highlighted one in terms of occurrence of flood due to its typical geographic location and diverse geomorphological characteristics. The district witnessed frequent floods because of high intensity of rain fall in the basin area of Bhairavi-Jalangi-sealmari rivers. Inflow of flood water from Ganga-Padma in high spate condition further aggravates the congestion of drainage. Lack of proper drainage is also responsible for flood in the upstream side in the western part as well as beyond the Berhampur town. Flood management may be undertaken through physical and socio-economic measures, which includes the scientific control of reservoirs; construction of new barrages, improvement of river channels, removal of human encroachment along river side, timely flood warning and forecasting, preparedness of essential services along with proper flood plain planning are indispensable. Addressing of socio-economic problems may help to combat the flood situation in an effective way.

Abstract

Organic farming is a method of crop and livestock production that involves much more than choosing not to use pesticides, fertilizers, genetically modified organisms, antibiotics and growth hormones. Organic fruit production essentially excludes the use of many inputs associated with modern farming, most notably synthetic pesticides and fertilizers. Organic agriculture, the innovative farming system can build-on and enhance the traditional knowledge and practices of local and indigenous communities. Indigenous Knowledge can be broadly defined as the knowledge that anindigenous (local) community accumulates over generations of living in a particular environment. ITK in fruit production is important for reducing the cost of cultivation, reducing the pollution and also the natural resource base. It is very important to understand these age old practices to address the local problems and to document it before is vanished away.

Introduction

ICT is an acronym for Information and Communication Technology.  The information refers to accessibility of digital data in an easy way to retrieve relevant facts. The communication refers to the medium or the way to transmit the information from one place to another place or one media to another media. The advancement in these areas refers to technology. The collectively ICT covers any product that will store, retrieve, manipulate, transmit or receive information electronically in a digital form. For example, personal computers, digital television, email, robots.

Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events). The change lasts for an extended period of time i.e., decades to millions of years has also been considered as climate change. The causing factors of climate change are biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. The affecting factors seems to be irreversible, it has become the today’s necessity to develop improved next generation technologies which processes the current and future shifts in the climate system. In particular, the Agriculture will be most affected domain due to climate over the next few decades (Brown and Funk, 2008). The development of crop modeling tools pointed out that climate change is likely to decrease agricultural production.

Abstract

More than 73% of its total population lives in rural areas and depends primarily on agriculture for livelihood. The performance of agriculture determines food and nutrition security which is important for reducing poverty and achieving sustainable growth. Production and productivity has increased manifold and yields of major crops like paddy, pulses, oilseeds and vegetables have more than trebled in the last four decades. The impressive long term growth in agriculture helped in taking the state out of famines and serious food shortages into one of the food surplus states and ensuring food, nutrition and livelihood security. The state is characterized by wide diversity and considerable spatio-temporal variations in growth and productivity. In fact, agriculture isincreasing with public investment in infrastructure including irrigation, establishing appropriate farming systems, developing suitable and affordable technologies and crop varieties, augmenting credit delivery and designing region and crop-specific plans. In this backdrop, a study was conducted to document the indigenous and organic farming technologies in selected communities of the state in tribal dominant Gajapati district of Odisha intended to help the farmers to be aware of their own innovative technologies for weakening balances on the environment due to intensive use of fertilizers and agrochemicals. 

Introduction
Climate change has become an issue of global concern and has a direct large scale impact on land and marine biosphere. The expected and unlikely events like increase in temperature, melting of glaciers and rising of sea level, increase in magnitude  and frequency of drought and floods, cyclones/tsunamis, desertification, heat and cold waves, snow fall are most threatening challenges that are being witnesses in the present era. Rain fall is likely to decline by 5-10 % over southern parts of India where as 10-20% increase likely over the other regions. There is probable decrease in number of rainy days over major parts of the country pointing at likely increase of extreme events of floods or drought. In India, salt affected soils currently estimated to be 6.73 M ha in different agroecological regions and  the area is likely to be almost turn to 20Mha by 2050. Framing breeding strategies to develop climate resilient varieties is necessary to mitigate adverse effects of climate change.

In our country livestock are mostly dependent upon cereal by-products or the crop residues such as straws, stovers etc., which are low in nutritive value. According to the National Commission on Agriculture (1989-90), there is a shortage of 40% of concentrates, 20% of dry fodder and 40% of green fodder for meeting the nutritional requirements of livestock. Consequently the livestock is surviving on low weight, low energy and thereby leading to problems in the production and reproduction. Nutritional deficiencies as well as imbalances are implicated as the cause of infertility in animals. The clinical signs observed with the deficiency of a specific nutrient as variable depending on the degree of the deficiency. The information on the important relationship between nutrition and health is necessary for recognizing and correlating the reproductive problems.

Introduction

Agroforestry system (AFS) is a form of sustainable land use that combines trees, shrubs, crops and livestock so as to increase and diversify farm and forest production along with conserving natural resources. Microorganisms play a crucial role in improving nutrient availability to plants, thereby decreasing the dependence on chemical fertilizers and achieve sustainable agriculture through agroforestry (Araujo et al. 2012). Arbuscular mycorrhizal (AM) fungi, plant growth-promoting rhizobacteria (PGPR), and the association of rhizobia with leguminous plants are symbiotic associations of high economic importance for increasing agricultural production. Yadav et al. (2010) studied soil biological properties under different tree based traditional agroforestry systems in a semi-arid region of Rajasthan, India and concluded that biological properties can be optimized in the soil under AFS. Many authors have reported that soil microbial biomass and microbial diversity are greater in the AFS due to the ameliorative effects of trees and organic matter inputs and the differences in litter quality and quantity and root exudates (Mungai et al. 2005; Sørensen and Sessitsch, 2007). Also, the presence of a large and diverse soil microbial community is crucial to the productivity of any agroecosystem. Moreover, more than one plant species in AFS have been reported to have shown a larger diversity and/or abundance of mycorrhizal fungi than monocultures (Cardoso and Kuyper 2006) and more efficiency in biological fixation of the nitrogen, especially in tropical soils (Freitas et al. 2010). Also, soil microbial biomass has other important functions in the soil such as nutrient cycling and the degradation of pollutants (Watanabe and Hamamura 2003; Araújo and Monteiro 2006).

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.

Introduction

Livestock sector plays an important role in the rural economy at national level and this sector is emerging as a driving force in agriculture by contributing towards the income and employment of rural households. Livestock contributed 16% to the income of small farm households that indicates importance of livestock sector as a whole. In 2010-11, livestock generated outputs worth Rs 2075 billion (at 2004-05 prices). Agriculture sector grew at low rate of 4.7% during 2013-14 and contributed 13.9% to National GDP (Economic Survey 2013-14). The livestock sector contributed over 4.1 per cent of the total GDP in 2012-13, that nearly accounts for 29.5% of the agricultural GDP (Economic Survey 2013-14) indicating a significant contribution of the livestock. Sheep and goats are an important livestock species for a large number of rural poor, especially socially backward, marginal and landless labourers in India. Sheep are mostly reared for wool and meat purpose. India ranks third in sheep population and account for nearly 6% of world sheep population, currently India has 65.06 million sheep as per Livestock census 2012.

Introduction

Dry lands cover nearly one-third of the earth’s total surface and characterized by high climatic variability in rainfall and temperature along with higher potential of wind and water erosion (Mainguet, 1991; Okin, 2000). Wind erosion has been identified as one of the overriding factors of desertification in regions characterized by strong and persistent winds through out an annual dry season (Le Houerou, 1996). Clear sweep of strong winds across sandy desert is the great hindrance in sustenance and progress of agricultural activities. The strong blowing winds on one hands takes away top fertile soil thus causing irreparable loss to soil productivity, on the other hand deposition of airborne soil particles (sand, silt and clay) block the roads, railways, water bodies, open canals and burry agricultural fields (Gupta and Aggrawal,1978; Prasad et al, 2004). To minimize erosion hazards of speedy winds and optimize production of agricultural crops, various efforts have been made in the past by adopting different soil conservation measures among which the windbreak/ shelterbelt plantations rank high due to their expected effects on wind velocity, microclimate and productivity. 

Introduction

Any kind of garden established on the roof top of building is known as roof garden, which provides the opportunity to cultivate the quality vegetables, fruits and flowers in home. In this system plants and grasses are grown on a nutrition medium placed above a waterproof membrane. Roof gardening is mostly adopted in urban areas. It uses for decorative benefit, roof plantings make available food, manage temperature, hydrological remuneration, architectural improvement, habitats  for wildlife, frivolous opportunities, and in large scale it may even have ecological benefits (Louise, 2009). This considerably increases human health as adding organic cultivation.

Introduction

Controlled perpetuation of plants is known as plant propagation. Plant propagation can be broadly classified in two types: sexual and asexual. In sexual propagation, the fusion of male and female gametes gives rise to a new plant, whereas in asexual propagation which is also known as vegetative propagation, the development of new plants takes place without the fusion of male and female gametes, that is, the new plant develops from vegetative plant parts. Various techniques of asexual propagation are adopted in plant propagation, such as: grafting, budding, layering, cutting, etc. So far cutting and layering are concerned; the new plants are developed on their own root system, but in grafting and budding on the others’ root system. It means that in these two techniques (grafting and budding), two plant parts are joined to form new plants; the one which forms the root system is known as rootstock and the one forming the shoot system is known as scion. Plant propagation is both a science and an art. The science of plant propagation requires knowledge of plant physiology, nursery cultural practices, and characteristics of the particular plant that you want to grow. The art of plant propagation cannot be taught in a book or classroom, however, because it consists of specific technical skills that must be acquired through innate ability or experience and often requires a certain feel.

Abstract

The utilization pattern of common property water resources revealed interesting pictures in different agro climatic regions of the eastern region. The group activities for utilization of water resources in Keonjhar district of Orissa indicate that the 10 different groups of farmers have been benefited differently from the utilization of common property water resources. The group nearer to sources utilized water resources intensely to their maximum benefit. The study reveals the different benefit level for different user groups under WTCER developed water resource. It is revealed that the use of CPR revealed a highest benefit cost ratio of 3.88 against lowest benefit cost of 1.24 for different groups. A case study of use of CPR water resources under irrigation tanks for different economic activities carried out by WTCER in Ganjam, Gajapati of Orissa and South 24 Praganas of West Bengal reveals that, the relatively poor HH (having land holding <1 ha) constituting about 76% of the population under the command of the sources completely depended on the system for livelihoods and for agricultural purpose in comparison to 54% of the households having land holding more than 1 ha. In most of the systems of irrigation tanks, the dependency on common property tanks for livestock rearing was found out to be more than 90% which sometimes goes as high as 100% for poor households.

Several cryogenic agents have been used in many countries for freezing and preservation of bovine semen like solid carbon-di-oxide (-79°C), liquid air (-183°C), liquid helium (-268°C) and liquid nitrogen (-196°C).  Liquid nitrogen is 4th coldest substance known and its small amount is converted into a very large amount (near about 700 times) of its volume when exposed to atmosphere.  It is a colourless, odourless, non-irritant, non-toxic, non-caustic, non-corrosive, non-inflammatory and inert gas having boiling point -196°C temperature.  Being a liquid it comes into good contact with the surface of the semen straws and constant storage temperature is maintained throughout the straw and due to these properties LN2 is most widely used refrigerant in the world.
