Abstract

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

Introduction

Vegetables are one of the potential crops in meeting the food requirements and improving the nutritional status of our people. They play a vital role in crop diversification, employment generation, and nutritional security and in improving the economic conditions of farmers.

Our country has made a tremendous progress in vegetable production and ranked as second largest producers of vegetables in the world with a total production of more than 125 million tons per annum. Our estimated demand is about 225 million tons by 2020 AD. This target can be achieved through use of improved vegetable varieties, hybrids and production technologies even with diminishing land and water resources.

In Indian vegetable scenario, IARI has contributed significantly by developing more than 168 improved varieties and 24 hybrids in different vegetables. Apart from high yielding, many of these varieties/F₁ hybrids are resistant to biotic and abitic stresses and also suitable for processing, value addition and export. Besides developing large number of improved varieties and F₁ hybrids of vegetables, IARI has developed/standardized improved hi-tech vegetable nursery and off-season production technologies which require commercialization by the entrepreneurs as these can bring quantum improvement

Introduction

The floriculture industry in India is characterized by growing traditional flowers (loose flowers) and cut flowers under open field conditions and protected environment conditions, respectively. India also has a strong dry flower industry, which contributes a major share to the overall trade. Other segments like fillers, potted plants, seeds and planting material, turf grass industry and value added products also contribute a share in the overall growth of the floriculture sector. 

Area and Production

With the rise in people’s investment in flower purchase for gifts at social ceremonies or for home decoration, the focus shifted to production of cut flowers too. The fresh increase in the area under flowers is more for cut flower production, but not necessarily at the cost of loose flower production.
A large share of the total world production area is in India. With an estimated area of 1,60,000 ha (2007-08), India perhaps is the largest production base in the world. The last decade and a half has witnessed significant increase in the area under flowers, which has tripled from 53,000 ha (1993-94).

Introduction

Self Help Groups (SHGs) are fast emerging as a powerful tool of socio-economic empowerment of the poor in rural areas. These are based on the principle by the people, for the people and of the people. Such groups are participatory processes to provide opportunities for people to share knowledge, common experiences and problems.

Self Help Groups (SHGs) of women in India have been recognized as an effective strategy for the empowerment of women in rural as well as urban areas, bringing women together from all spheres of life to light for their rights or a cause. Since the overall empowerment of women is crucially dependent on economic empowerment,  women through these SHGs work on a range of issues such as health, nutrition, agriculture, forestry etc. besides income generation activities and seeking micro credit. “SHG is a small, economically homogeneous and affinity based group of people who have decided to save and contribute to a common fund to be lent to its members as per the groups decisions”. Generally, a ‘Self Help Group’ (SHG) is formed when members of a community, who have the same or similar problem, come together, meet, share experiences, have discussions and thereby arrive at solutions.

ABSTRACT

Punjab is the richest state in the country in term of per capita income and has earned the name as food bowl of the country by putting 84-85 per cent of its geographical area under highly intensive, technical and mechanical agriculture with cropping intensity as high as 185 per cent and contributing more than one third of rice and half of its wheat production to the central pool of food reserve. The food grain production in the state has increased approximately twelve times in a span of about 50 years after independence from 20 lac tones in 1950-51 to 234.89 lakh tonnes in 2002-2003. Achieving this high productivity without caring for natural resources has resulted in a considerable loss in the inherent production potential and deterioration of soil health. As a result, man is getting serious warning signals in the form of lowering of water table, drought, high rate of environmental pollution, extremes of climatic parameters, etc. Agriculture in the state has become too intensive, wasteful and reckless and the radical changes are required to maintain the balance. Therefore, there is a strong thinking to diversify farming in the state to maintain the sustainability of the whole system. The state government is stressing hard to save the natural resources through the diversification in traditional crop rotation and adopt resource-conserving measures.

ABSTRACT

Eastern part of the Uttar Pradesh falls in mid-Gangetic plain commonly called as ‘Purvanchal’. It is divided into three ecozones : i) North eastern tarai, ii) Eastern Plains, and iii) Vindhyan. Most of the farmers of the region have subsistence agriculture with small land holding. Although total forest area is 10.69 per cent of the geographical area, the actual well stocked forests (medium and good forests) in the region are confined to 3.51%. Vindhyan zone indicates higher dependence for fire wood (35% of the total need) on natural forests. Cow dung is major source used as fuel in Eastern plains (65% of the fuel requirement). The cropping systems are different in rainfed and irrigated lands. Surveys of different parts of the eastern U. P. indicate that people have a progressive attitude towards agroforestry. However, due to land hunger most of the farmers develop homesteads. Agrihorticulture system is most popular system adopted by large and medium farmers in the region. Agrisilvihorticulture system is adopted by the farmers of Eastern plains and North eastern tarai zones. Agrisilviculture, Silvihorticulture, Agrisilvihorticulture and sivipastoral systems researched by us, are recommended for adoption by the farmers.

ABSTRACT

Modelling has been used in natural sciences since centuries in one-way or the other. However, system modelling as a discipline in itself is established in the recent years. Agroforestry modelling is a complex process that essentially involves at least two elements viz. tree and crop, where tree is the long term and crop is the short-term component. Agroforestry models, usually, predict tree growth and yield and the reduction/enhancement in crop yield as influenced by the tree component in temporal and spatial sequence. In this paper the need of modeling, stages of model development, its validation and classification of models are given. The models, which are relevant to agroforestry, have also been given.

INTRODUCTION

Agroforestry combines agriculture and forestry technologies to create more integrated, diverse, productive, profitable, healthy and sustainable land use systems. According to the Association for Temperate Agroforestry - “Agroforestry practices are intentional combinations of trees with crops and/ or livestock that involve intensive management of the interactions between the components as an integrated agroecosystem”. These key characteristics are the essence of agroforestry and are what distinguish it from other farming or forestry practices. To be called agroforestry, a land use practice must satisfy all of these criteria:

Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signalling, and acting as structural components of cell membrane. Lipids have applications in the cosmetic and food industries as well as in nanotechnology.

Lipids may be broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, liposomes, or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or “building-blocks”: ketoacyl and isoperen groups. Using this approach, lipids may be divided into eight categories:fatty acids, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids and polyketides (derived from condensation of ketoacyl subunits); and sterol lipids and prenol lipids (derived from condensation of isoprene subunits).

Although the term lipid is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides. Lipids also encompass molecules such as fatty acids and their derivatives (including tri-, di-, monoglycerides and phospholipids), as well as other sterol containing metabolites such as chloestrol. Although humans and other mammals use various biosynthetic pathways to both break down and synthesize lipids, some essential lipids cannot be made this way and must be obtained from the diet.

Plant hormones - They are defined as:

1. Small
2. Organic compounds;
3. Synthesized by the plant;
4. Active in low concentration (<10^-6);
5. Promote or inhibit growth and developmental responses;
6. Often show a separation of the site of production and the site of action (although this isn’t as clear a distinction as in animals).

Based on these criteria, would the following substances be considered hormones? Ca²⁺, sucrose, 2 4 - D, glycine, or K⁺?

Farming system is an integrated set of activities that farmers perform in their farms with available resources and circumstances to maximize the productivity and net farm income on a sustainable basis. The farming system conceptually is a set of elements or components, i.e., soil, water, crops, livestock, labour, capital, energy and other resources that are interrelated and interact among themselves. At the centre of the interaction lies the farmer exercising control and choice regarding the types of results of interaction. The income of cropping alone from small and marginal farm is insufficient now to sustain the farmers family. A judicious mix of any one or more of these enterprises should complement the farm income and help in recycling the farm residues / wastes. The selection of enterprises must be based on the cardinal principles of minimizing the competition and maximizing the complementary between the enterprises. Of late, the researchers on multidisciplinary approach greatly realized and started developing the various farming systems models in accordance with the agro-eco systems zones.

Farming System thus may be defined as a complex interrelated matrix of soil, plants, animals, implements, power, labour, capital and other inputs controlled in part by farming families and influenced to varying degrees by political, economic, institutional and social forces that operate at many levels. The farming system therefore, refers to the farm as an entity of inter-dependent farming enterprises carried out on the farm. The farm is viewed in a holistic manner and the farmers are subjected to many socio-economic, biophysical, institutional, administrative and technological constraints.

Fermentation plays a major role in our diet and give the basic foods like bread, yoghurt, wine and cereal and legume based traditional fermented foods. The development of fermented food products can be considered as one of the greatest achievements of human civilization and goes back thousands of years. It arose from the necessity to conserve foods, to make them more digestible and also more enjoyable. During the centuries, man learned by trial and error to conduct the fermentation processes by changing physical and chemical parameters in the basic food ingredients. It took much longer, however, to discover the cause of fermentation processes: only towards the end of the 19th century it was demonstrated, that baker’s yeast is the cause of alcoholic fermentation. Through the development of the technique of "pure microbial culture", the basis for a controlled use of microbes in food industry was established.

The unique feature of fermented foods is the vital role of microorganisms that bring about essential bio-trasformations of the substrates during fermentation contributing number of desirable properties such as improved product shelf life, enriched diet with improved flavor and texture, increased safety, enriched nutritional supplement and probiotic functions. Fermentation is a chemical reaction carried out by many types of microorganisms to obtain energy. Fermentation is a process for production of a product by means of mass culture of microorganisms. In fermentation, microorganisms breakdown complex organic compounds into simpler substances. Although chemical changes and microbial growth usually mean food spoilage, in some cases fermentation is desirable and microorganisms are actually added to foods. For example, in the production of beer, wine, and other alcoholic beverages, yeasts convert sugar into ethyl alcohol and carbon dioxide. In the making of yogurt and cheese, lactic acid bacteria convert lactose, a sugar found in milk, to lactic acid. Alcohol, acids, and other compounds produced in fermentation act as preservatives, inhibiting further microbial growth. In addition to its use with alcoholic beverages, cheese, and yoghurt, fermentation is used to produce yeast bread, soy sauce, cucumber pickles, sauerkraut, and other traditional fermented food products. The variation in agroclimatic conditions prevailing in India and diverse form of dietary culture of various ethnical groups produced traditional fermented foods such as idli, dosa (rice-legume based), vada, papad, wari, balle (legume based), bhatura, jelabi, nan (wheat based), paneer, shrikhand (milk based).

2.1 Introduction

Each step in the food industry system e.g. food production, processing, transportation, storage, distribution and marketing, has some impact on the environment and there is much concern about environmental pollution. Due to the highly diversified nature of the food industry, various food processing, handling and packaging operations create wastes of different quality and quantity, which, if not treated, could lead to increasing disposal problems and severe pollution problems [24]. The preservation of the natural environment from industrial pollution is currently receiving much attention. In food industry, the most important problem is treatment and disposal of large quantities of waste water, a by-product of various processing operations. It is one of the largest industry groups comprising the manufacturing sector of the U.S. economy [47]. Likewise, India is the world’s second largest producer of food next to China, and has the potential of being the largest food processor. The total food production in India is likely to double in the next ten years [22]. Flour and grain; soft drinks and carbonated water; breweries; starch and miscellaneous food products; meat, poultry and fish; tea, coffee and other beverages; fruit juices; animal feed; sugar; distilleries and blending of spirits; cocoa, chocolates and sugar confectioneries; agricultural and food chemicals and industrial packaging are important sub-sectors of the food processing industry. Food processing projects involve the processing and packaging of meat products, fish and shell fish, dairy products, fruit and vegetables, grains and beverages production. It includes refinement, preservation, improvement of product, storage, handling, packaging and canning (Fig. 1). The processing may involve receiving and storing raw or partially processed plant, animal or other food materials, processing the raw materials into finished products, packaging and storing the finished products.

Introduction

Groundwater is an important source of irrigation in India and has played a major role in increasing the food production. About 50 per cent of total irrigated area in the country is dependent on groundwater (Central Water Commission (CWC), 2000). Productivity of groundwater is normally more than the surface water due to the fact that it is available at the point of use, requires minimum conveyance infrastructure, is available on demand and maximizes the application efficiency. However, in past few years, excessive and unplanned groundwater pumping in certain parts of the country has resulted in depletion of groundwater resources. Water table in these region is going down day by day and making it beyond the reach of poor farmers. Therefore, keeping the water table in the desirable range is a major concern. This can be achieved by adopting proper pumping rate and pumping schedule. Groundwater modelling has successfully been used for deciding the pumping rate and pumping schedule. Groundwater modelling refers to simulation of groundwater behaviour under varying pumping and recharge conditions. A groundwater model is simply a set of equations, which describe the physical processes active in the aquifer subjected to certain assumptions. While the model itself obviously lacks the detailed reality of the groundwater systems, the behaviour of the validated model approximates that of the aquifer.

In this chapter, an attempt is made to emphasize the fact that while no country in the World is safe from geohazards, a proper understanding on their causes, ways to mitigate them and surviving techniques would help reduce the life and property loss. Each geohazard has its own characteristic way of potential impact and hence classifying vulnerability of different regions and creating awareness on potential impact is essential. In addition to providing basic information on geohazards, this chapter presents a conceptual model on hazard mitigation, rescue and relief operations.

INTRODUCTION

Every year, thousands of people are killed by volcanic eruptions, earthquakes, landslides and floods. These natural causes damage human settlements and infrastructures (GOI, 2004) inflicting life and economic loss. As human population increases, habitation on hazardous and or vulnerable land becomes more common and the risks posed by these hazards increase. The need to observe their behavior, understand them better and mitigate their effects become ever more urgent (IGOS, 2003). Decades of research may have contributed towards betterment of our understanding on the processes of geohazard formation but still a long way has to be covered to develop better mitigation procedures.

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

INTRODUCTION

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

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

INTRODUCTION

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

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

impacts other speheres and that too on a distal place! This chapter explains how global warming affects remote places like highlands of Bhutan. Severe hot summers during the year 1994 led to excessive melting of glaciers in the higher Himalayas. The exceptional melting contributed enormous amount of melt water to the lake basins, which caused breach of the morainic dam and consequent enlargement of the outlet of the Luggye Tsho and the Tshopda Tsho, Bhutan. Floods followed the breach on October 7, 1994. These floods destabilized the slopes on either bank of the Pho Chhu near Tshopda Tsho outlet making them prone to landslides. The flash floods also eroded the left lateral moraine of the Raphstreng Tsho, which had disturbed the original angle of repose. The Raphstrcng area is also prone to ice avalanches, rock glaciers, surge of which can damage the rim and also cause spillover of water. Examination of geological, geomorphological, geotechnical, microclimatic and hydrographic information in and around the glacial lakes led to improved understanding of breach characteristics based on which mitigation measures were suggested and implemented in the years 1996-97. Since then the lakes have remained intact. From this case study and satisfactory performanceof mitigationmeasures suggest that similar integrated studies have to be conducted for thorough understanding of hazard prone areas based on which mitigation measures have to be implemented for successful reduction of impacts.

INTRODUCTION

The Lunana area, situated in the northern district of Gasa, is one of the most extensively glaciated terrains of Bhutan (Fig. 1). In response to the general global warming, these glaciers like those of other parts of the Himalaya are in a state of steady retreat, often leaving behind a chain of lakes. Though the glacial lakes endow scenic beauty, they also pose environmental hazards, due to frequent bursting of their morainic dams and consequent flash floods. The last lake-burst occurred on 7^th October 1994, leading to floods in the Pho Chhu River. Following floods, the Geological Survey of India in collaboration with the Royal Government of Bhutan, investigated the Lunana area to identify the causes and effects of the floods and suggest remedial measures. More than a decade had passed since the implementation of mitigation measures and there has been no such breach and flood despite continued Glacial Vetreat during to Global Warming. This chapter describes the characteristics of these glacial lakes, nature and results of the study and mitigation efforts.

Nursery management is indeed a very important operation in successful growing of vegetables especially those, which are raised through seedlings in properly managed nursery beds. Raising nursery from seed provides an easy and convenient way to nourish tender young seedlings in a well-managed small and compact area. The nursery area can be conveniently protected from natural hazards, seed borne diseases and insect-pests and can be well managed economically. Some of the vegetable seeds are very costly, for which it is necessary to raise nursery in the most-optimum conditions. In areas where land holdings are small (in hills), nursery raising helps in making economical use of land for about one month and provides enough time to mature for previous crop, harvesting, threshing and land preparation for next crop. Most of the vegetable crops like cabbage, cauliflower, tomato, eggplant, sweet pepper, hot pepper, onion, celery, parsley, lettuce, etc. can successfully be raised through seed by growing them in the nursery and then transplanting in the field.

“A vegetable nursery is a place or an establishment for raising or handling young vegetable seedlings until they are ready for more permanent planting.”

Nursery can be maintained either for personal or commercial purpose, and each has its own advantages and disadvantages. Seedlings raised for own planting will be true to type, sound and healthy. On the other hand, seedlings purchased from outside may not be true to type, vigorous and healthy and may not arrive at destination in due course of time.

Definition and History

The dictionary meaning of property is ‘estate whether in lands, goods or money’; such property is often referred to as tangible, material or physical property. The laws of the land protect the ownership of and the associated rights to physical property. In contrast, “intellectual property is an idea, a design, an invention, a manuscript, etc. which can ultimately give rise to a useful product/ application. The development of such property, as a rule, requires intellectual inputs, ingenuity and innovativeness; it also demands considerable monetary and other resources. Therefore, inventor of an intellectual property would like to ensure at least a fair reward for copied, imitated or reproduced; this minimizes the returns to the original inventor. Intellectual property right recognizes the right of an inventor to derive economic benefits from his invention (i.e. intellectual property); this right is called intellectual property right (IPR), (Singh, 2002). The governments, however, recognize the IPR, only so long as it is not to the detriment of the society. In India, innovation and novel techniques were retained within the families / small social groups that developed them, and there was no other system of protecting their rights to the knowledge so generated. The brief history of intellectual property right in India is:

In 1856, the British Government in India introduced the Act of Protection of Inventions. This act was based on the British Patent Law of 1852.

In 1872, Patents and Designs Protection Act was passed.

In 1883, the Protection of Inventions Act was introduced. It was consolidated as Inventions and Designs Act in 1888.

On 15 August 1947, the Indian patents and designs came under the management of Controller of Patents and Designs.

The Indian Patent Act (1970) was introduced in the parliament in 1965, was modified in 1967 and passed in 1970.

Protection of designs is covered by the Indian Patent and Design Act (1911) with amendments in 1978 and amended rules in 1985.

Trademark protection is in force since 1 June 1948 under the 1940 Act. This act was amended as Indian Trade and Merchandise Marks Act (1958), which became effective on 25 November 1959.

The copyright laws in India are as per international standards.

Vegetable seed cleaning and processing are two important aspects of seed post-harvest management. These steps are very essential to maintain the quality of the seed till its next sowing season. The quality of seed produced is dependent on the moisture content and various admixtures. To provide quality seed to farmers, it is very essential to clean seed to its maximum quality. The seed quality attributes like moisture, free water activity, to be controlled in germination, vigor and viability are upgraded during seed cleaning.

Seed cleaning is the term used as a part of processing means separation of admixtures from a particular seed lot. The physical characters like bigger clods, sand, soil, chaffy material, inert matter etc. will be removed during seed cleaning. Seed processing on the other hand is relatively broad term referring to the process of removal of dockage in a seed lot and preparation of seed for marketing is called seed processing. The price and quality of seed is inversely related to dockage, which should not exceed a maximum level permitted for different crops for seed certification. Due to the operation of processing the level of heterogeneity of seed lot gets narrowed down. The heterogeneity occurs in a seed lot due to following reasons:

ABSTRACT

Of late, the importance of integrated study of multi-theme data is being realised in geological mapping and mineral exploration programmes. The usefulness of such a study lies in the fact that data integration and interpretation in a conjunctive mode enables to infer more information than the sets can separately provide. The present paper presents several case studies, illustrating the usefulness of multi-theme data integration in geological mapping and mineral exploration.

1. INTRODUCTION

Integrated study of multi-theme data is being practiced in the recent times in the geological mapping and mineral exploration campaigns. Such a study, in a synergetic fashion, helps to extract more meaningful information than from the study of individual datasets. It not only helps in deciphering regional geological picture, but also in the precise location of drilling targets, thereby yielding rich dividends for the expenditure incurred in the mapping and mineral investigations. Besides, the success ratio of the mineral investigations has also shown a significant increase, resulting in the discovery of more mineral

deposits. Hence the integration of multi-theme data is of paramount importance for the success of geological mapping and mineral investigations.

Phosphorus is present in soil both in inorganic form and organic form. The inorganic P can be divided into different pools. The major active inorganic forms are: P bound to aluminium (Al-P), iron (Fe-P), calcium (Ca-P) and silicate minerals and relatively less active forms are occluded and reductant soluble forms of P. On the other hand, the principal organic P compounds present in soil are (i) inositol phosphate, (ii)phospholipids, (iii)nucleicacid and other unidentified esters and phosphoproteins.

22.1 Determination of Available Soil P

The availability of soil P to plant varies greatly depending upon the reaction, minerological composition and amount of the soil colloid. Very little P is present in the soil solution except in recently fertilized or sodic soils. The type of phosphate ions present in the soil solution depends on the soil pH. In soils of neutral to slightly alkaline pH, HPO₄^2-ion is the dominant form. In slightly or moderately acidic soils, both HPO^-and HPO^2-ions prevail. At strongly acidic soil HPO 244 24 ion tends to dominate, while above pH 9.0, the PO₄^3-ion becomes more important - than H₂PO₄ .

As the P is drawn from soil solution largely through diffusion by the plant, it is replenished from solid phase pool of available P. P fertilizer is added to recharge this pool.

Development of Agriculture in the World and in India

Agricultural ecosystems will increasingly be called on to deliver food and fiber for a demanding and expanding global population. Until recently, increased production relied on expansion of the amount of land under cultivation and irrigation. Since World War II, production advances have relied on genetics and plant breeding, advances in fertilizer and pesticide use and improved cultural management (Matson et al., 1997). Since 1950, agriculture worldwide has expanded cereal production by an average of 2% per annum while population has increased by 1.9% per year (Borlaug and Dowswell, 1994).

Modern science-based agriculture had its beginnings in the late 19^th century with improved traction and tillage equipments. However, it was not until after World War II that the research findings that led to the modern-day productive systems in the United States and later in European and other developed countries. The expansion was directly related to the great demand for food to support the Allied war effort. Knowledge bases developed in plant genetics, physiology and pathology, along with a ten-fold increase in fertilizer use, advances in seed technology, weed control, irrigation and cultural methods allowed the development of the systems that dominate agriculture in many of the countries today. Corn or maize responded dramatically to the advances in production technology. Maize yield in the United States has increased more than 300 per cent over the past 50 years and continues to rise. Maize production technology has been delivered worldwide (Borlaug and Dowswell, 1994).

Microscope is an instrument to magnify and enable to see the microorganisms by us.

Microscopes are of two types. Light and Electron microscope.

Basic Principles of light microscope

The light is the primary source on which magnification is performed. The magnification is obtained by a system of optical lenses using light waves. These light microscopes can be further classified into

Eukaryotic, spore – producing, achlorophyllous organisms with absorptive nutrition that generally reproduce both sexually and asexually and whose thallus is usually filamentous, branched somatic structures known as hyphae, typically surrounded with cell wall.

Mycology – Study of fungi

The fungi can be divided into two groups namely

True fungi: Chytridiomycota, Zygomycota, Ascomycota, Basidiomycota

Additional phyla: Myxomycota, Dictyosteliomycota, Acrasiomycota, Plasmodiophoromycota, Oomycota, Labyrinthulomycota, Hypochitridomycoya.

The Internet is a worldwide network of networks connecting millions of users, spread across continents, exchanging thousands of gigabytes of information, accessing numerous databases that cover everything from cooking to astronomy, all relatively inexpensively. The Internet offers virtually unlimited amounts of information related to animal medicine and provides all the tools to access it. ‘www’ is probably the most famous three letters of the last century, signifying a series of servers that are interconnected with each other through hypertext transfer protocol or ‘http’. A significant part of the credit for increasing the popularity of the Internet belongs to the World Wide Web. It is always better to use evaluated web resources as the quality of websites is a problem in cyberspace.

1. INTRODUCTION

The terms antioxidants and free radicals are being very effective used nutritionists and other health professionals. Antioxidants are compounds are good for health and free radicals are harmful. In general, antioxidants neutralize free radicals that are generated in the body and prevent damage to cell proteins, lipids and carbohydrates. Antioxidants can be water-soluble or lipid-soluble, thus they exist within the lipid or within the water portion of cells. Antioxidants are substances when present in food or in body at low concentration retards or prevents undesirable oxidation of substrates by free radicals.

Within the human body, millions of processes are occurring at all times. All cells require oxygen to generate energy; higher eukaryotic organisms cannot exist without oxygen. Unfortunately, that same life giving oxygen can create harmful side effects which cause cell damage and lead to chronic disease. Damage caused by free radicals is called oxidation. Oxidative stress is the disturbance in the prooxidant-antioxidant balance in favour of the former, leading to the potential damage.

Those plants which are completed their life cycle in a season or a year, is called annuals. Thre are many types of annuals.

1. On the basis of seasons:
   1. Rainy annuals: Balsam, Cock’s comb, Amaranths, Gaillardia, Torenia, Gompherena etc.
   2. Summer annuals: Zinnia, Kochia, Tithonia, Sunflower, Cosmos, Coreopsis.
   3. Winter annuals: Remaining annuals.

Indian agriculture is characterized by small farm holdings. The average per capita land holding is speculated to squeeze to 0.10 ha by 2050. The proportion of marginal holdings is to swell more due to the growing population, inheritance laws of division of land and diversion of agricultural land to non-agricultural purposes. But we need around 457 Mt food grains to feed our nation by 2050 as against the present level production of about 257 Mt. Significant changes are also taking place in domestic and international demand for crop products due to improvement in income and standard of living, fast urbanization, and changing life styles and food preference patterns. The food demand is projected to grow annually at 2.0 % for cereals as against 3-4 % for edible oils and pulses, 4-5% for milk and milk products, meat, fish, eggs, fruits, vegetables, sugar and gur. In contrast, association of emerging problems like declining per capita land availability, increasing nutritional insecurity, decrease in factor productivity, increasing risk with individual farm component, unsustainability of cropping systems and unwillingness of young farmers towards farming lead to an apprehension in achieving the target. Farming system which aims at long term productivity, profitability, recycling of resources and employment generation, comes out as a major strategy to tackle all such problems. In farming system, various components of farming are integrated based on the cardinal principles of minimizing the competition and maximizing the complementarity between the enterprises so as to improve productivity and profitability as well as resource conservation along with maintenance of the environment. A survey conducted by the AICRP on Integrated Farming Systems indicates existence of 19 predominant farming systems with majority (85%) as crop + livestock (Gangwar and Ravisankar, 2014). Crop dominant farming systems are existing in most of the states such as Andhra Pradesh, Bihar, Chattisgarh, Goa, Haryana, Jammu and Kashmir, Jharkhand, Kerala, Karnataka, Madhya Pradesh, North-East, Maharashtra, Odisha, Punjab, Tamil Nadu, Uttar Pradesh and Uttaranchal while livestock dominant systems, are present in Rajasthan and Parts of Gujarat. West Bengal, parts of Odisha and Assam states have the fisheries as a major source of income to the existing farming systems. The scope for promotion of horticulture (fruit) based systems exists in Jammu and Kashmir, Himachal Pradesh, Maharashtra, parts of Uttar Pradesh and in Sikkim while plantation dominant systems, are available in Andaman and Nicobar Islands and Kerala. Further, the contribution of crop and livestock to gross income of existing farming systems in 732 marginal households in 30 districts of 20 states in various NARP zones of India indicates that in majority of the place crop component contributes more than 50 % while at few districts such as Samba (Jammu), Aurangabad (Maharashtra), Mehsana and Panchmahal (Gujarat), livestock component contributes either equally or more. Thus cropping systems play a pivotal role in most of the farming systems of India.

Mechanization of agriculture is essential for optimal utilization of vital inputs for crop production system such as soil, water, seed, fertilizer, pesticide and labour force leading to higher productivity and reduced cost of production for greater profitability. Thus with the support of mechanization, the agrarian sector as an enterprise needs to become sustainable and economically competitive which coincides with the objectives of the Integrated farming System concept. Mechanization also imparts capacity to the farmers to carry out farm operations with dignity, comfort and freedom from drudgery, making the farming agreeable vocation for educated rural youth as well. It helps the farmers to achieve timeliness and precisely meter and apply costly input for better efficacy and achieve higher productivity with reduced application of inputs. Small and marginal farmers now make use of high capacity agricultural machines on custom hire basis to enjoy the economic benefits. As such, the broad subject of agriculture can be understood as production agriculture, which takes care the field operations in the crop production system for higher productivity and post production agriculture, better known as post harvest technology which looks for reducing the loss of produce and value addition for economic gains. The IFS outlines the need of sustainability for farmers with limited resources of land, water and economy while mechanization aims at maximizing the profitability in agricultural system with a commercial attitude. Since the availability of labour force during peak hours of need and hike in wage very often creates hindrance in production and post production agriculture, mechanization can be the right answer to harness the benefits of IFS approach.

Commercialization is essential for agricultural development, which, amongst other things, entails mechanization of agriculture to reduce the cost of production and to increase the yield of crops. In some instances, agricultural commercialization may take place even without mechanization. However, due to the ever increasing agricultural labor scarcity in developing countries, an extensive scale agricultural commercialization may not be possible without mechanization.

The various farm operations involved in crop production system are land leveling, tillage for seed bed preparation, sowing and planting, weeding and interculture, spraying, harvesting and threshing. The mechanization of all these operation has been appreciated by the farmers which are discussed in the following paragraphs.

I. ROLE OF INTELLECTUAL PROPERTY

The international community has set itself the target of reducing the proportion of people below poverty line to half by 2015, along with associated specific targets for improving health and education and environmental sustainability. The Millennium Development Goals, adopted at various international fora, recognize the crucial importance of reducing poverty and hunger, improving health and education, and ensuring environmental sustainability. It is important to know whether and how intellectual property rights (IPRs) could play a role in helping the world meet these targets — in particular by reducing poverty, helping to combat diseases, enhancing access to education and contributing to sustainable development, protecting our cultural heritage, safeguarding the food security for the country. It is also necessary to deliberate whether and how they create obstacles to meeting those targets and, if so, how those obstacles can be removed.

There are strong views from both sides on the protection and enforcement of IPRs though there is no data to check these views objectively. Some argue strongly that IPRs are necessary to stimulate economic growth, which in turn, helps in poverty reduction. By stimulating invention and new technologies, IPRs help to increase agricultural or industrial production, promote domestic and foreign investment, facilitate technology transfer and improve the availability of medicines necessary to combat diseases. They are also of the view that there is no reason why a system that has worked for developed countries would not work for developing countries. Others argue equally vehemently the opposite. IPRs do little to stimulate invention in developing countries, because the necessary human and technical capacity may be absent there. In assessing these opposing arguments, it is important to remember the technological disparity between developed and developing countries as a group. What role the intellectual property can play to plug this gap is a serious subject for every developing nation? For this, it is also pertinent to know about the IPRs, the challenges they pose to the legal system in general and to the Indian legal system in particular, and their basic rationale to take a considered approach in their implementation.

I. INTRODUCTION

Procedural remedies for the infringement of one’s right are not enough by themselves unless they result in some reliefs of substantive nature whereby it can reasonably be said that these reliefs, temporary or permanent, as the case may be, are enough in the circumstance to make good or, say, compensate the genuine loss of the aggrieved party to an infringement suit. The substantive remedies available to a successful plaintiff at any stage in any suit for patent infringement could, however, be derived from the express as well as by necessary implication of the provisions of the Patents Act, 1970 dealing with the “Reliefs in suit for infringement”. Its Sec. 108 declares in terms quoted below:

John H. Davis of Harvard University first used the term agribusiness in 1955. In 1980s it was given three connotations: (1) synonymous with term agriculture, (2) synonymous with agricultural economics and (3) a modified concept of agriculture, excluding farming, or the off-farm aspects of agriculture.

Agribusiness is defined as all business enterprises or sells to farmers/traders/consumers. The transaction may involve either an input or a produce or service and encompasses items such as:

• Productive resources (feed, seed, fertilizer, equipment, energy, pesticides, machinery, etc.)
• Agricultural commodities –(raw and processed commodities of food and fiber)
• Facilitative services (credit, insurance, marketing, storage, processing, transportation, packing, distribution, consultancy, soil testing etc.).

Domestication of animals was followed by the provision of shelters for protection which also modified the climate to suit the species housed for improving the productivity and reproductive efficiency. Climate is the long term average condition of the meteorological variables in a given region. The climate is divided into macro climate and micro climate. Macro climate is the general large scale climatic conditions of the open atmosphere in a large area. Micro-climate is the climatic conditions directly surrounding the animal or the physical environment in the immediate vicinity of the animal. The environment includes all the combination of conditions under which the animal lives. The immediate variables that affect the production and reproduction of animals are its micro climatic variables. The animals have requirements of their own. The environment influences where and how animal lives. Domestication has resulted in man dictating where and how animal lives. Thus breeds of livestock evolved in temperate regions have been introduced into tropical area with high rainfall, humidity and temperatures. Homeotherms are a group of animals which maintain their deep body temperature essentially constant. All the domestic animals are homeotherms. In the case of an inert body, basic thermodynamic forces establishes an equilibrium in which the body attains the same temperature of the surrounding environment. The same law applies to homeothermic animals also. Therefore, these animals will have to make compensatory physiological and behavioural adjustments to keep a constant deep-body temperature. While digestion of food takes place in the body of animals, a portion of the energy in the feed is converted into heat. This metabolic heat plus the heat gained from the environment through conduction, convection and radiation results in excess heat gain to the animal, which has to be dissipated, if heat balance is to be maintained. For this the animal depends on various physiological and behavioural functions. This balancing act by which a constant normal core temperature is maintained is known as homeothermy. Heat production is regulated by hormonal secretions, changes in muscle tone, shivering and by voluntary muscular activity. Heat loss is controlled by vasodialatation, increasing the cutaneous circulation and evaporative loss. The animal reduces its feed intake as well as production, drink more water. In long term the hair coat becomes lighter with less insulation. The animal will also exhibit postural changes and behavioural adjustments. They will try to increase surface area, reduce physical activity and seek shade.

Abstract

Landslides are the most common hazards in hilly regions. Rapid development and the resultant uncontrolled interactions with ecosystems are the major reasons for the landslides, besides the rainfall. So, the assessment of landslides hazard vulnerability is a prerequisite before making any developments related to settlements, hill resorts, hydropower projects and the related network of Ghat roads. The present study deals with the assessment of landslides in two different sites; Site-1 located in the Ghat section of Yercaud hills between 10/4 and 29/6 km stones in the southwestern slopes of Shevroy hills, Salem, and the Site-2 located in the Ghat road between Lower camp and Kumuli in Theni districts, Tamil Nadu. The Theni ghat road in the National Highway-220 is connecting Tamil Nadu with Kerala and is the lifeline for Sabarimala, Tekkadi and Munnar. Besides, a series of pan stacks conveying water from Periyar reservoir in Kerala to the power house located at Lower camp in Tamil Nadu also lie in this stretch of hills. Landslide vulnerability mapping was carried out in an area of 130sq.km in Site-1 and 6.7 sq.km in Site-2 by assigning numerical values to the causative factors of slope instability such as lithology, structure, slope morphometery, relative relief, land use and land cover, and ground water conditions following the BIS code No. 14496 (1998) for preparing landslide hazard zonation maps. The study in Yercaud hills revealed that out of 12 slope facets, facet 1 to 6, 9 and 12 fall under moderate landslide hazard zone whereas facets 7, 8, 10, and 11 fall under high hazard zone. The area falling in facets 3, 4 and 5 of Kumuli ghat section fall under high landslide hazard zone, the slope facets 1, 2, 9 and 10 fall in the moderate hazardous zone and other facets in low hazardous zone.

Abstract

The state of Nagaland located in the northeastern part of the Indian subcontinent is also prone to landslides similar to the other north eastern states due to the softer lithologies, intense deformation and extensive anthropogenic activities. So in order to understand the landslide vulnerability and to evolve remedial measures, a 12 km stretch of the NH-2 from Kohima town in the south to Zhadima junction in the north was studied. The study comprises the preparation of landslide hazard zonation map using BIS method and detailed studies in six major landslides involving RMR, SMR and Kinematic analysis and also the suitable remedial measures for such landslide phenomenon.

Abstract

Due to fragile lithology belonging to Disang and Barail groups of the Cretaceous-Tertiary period, intensive structural deformation related to collision tectonics, extensive weathering and the anthropogenic activities in the form of slope cutting for the development and widening of roads lead to frequent landslides in the state of Manipur, India. In this connection, the road section between Tengnoupal and Sita has been studied to understand the landslides vulnerability and to evolve mitigation strategies. The study involved the Petrochemical analysis to elucidate the weathering potential of the rocks, kinematic analysis to understand the network of joints and the strain, slope stability analysis to prepare Land Hazard Zonation mapping and estimation of factors of safety in selected locations. On the basis of these studies, long & short term remedial measures were suggested to mitigate the landslide hazards.

Abstract

The present study deals with the slope instability analysis of a vulnerable stretch of 16 km between Pratapgarh road intersection and Mahabaleshwar town, which is a part of the state highway-72, Satara district, Maharashtra, India. The highway remains closed during the monsoon seasons, due to the recurrent instances of cut slope failures. So the present research work was conducted with an aim to study the reasons, extent and mechanism of the cut slope failures along the road sections as well as optimization of tools for the assessment of road cut stability of the area. The 16 km stretch was divided into seven vulnerable sections (M1; near Mahabaleshwar - M7; near Poladpur) based on the geological, geometrical and structural attributes. The slope forming mass primarily consists of laterite, weathered basalt and fresh jointed basalt, which are interbedded with red bole at some sections. Limit equilibrium, finite difference and finite element simulation were performed for seven cut slope sections, using similar geometries and material strength attributes for all the analyzing techniques. The assessment was carried out for both dry and saturated conditions to emulate the monsoons. The factor of safety yielded through the limit equilibrium method was the most conservative of all the tools; while the finite element method gave the least conservative figures in terms of factors of safety, being close to the field observations, the safety factor results of finite difference methods were between the limit equilibrium and finite element methods. The cut slope sections composed of weathered basalts and laterites (M1, M2, M3, M6) were found most vulnerable to failure during rains, while the sections composed of fresh jointed basalts (M4 & M5), though overall stable, are susceptible to planar and wedge failures.

8.1 Introduction

After deciding the optimum size of farm pond and its dimensions, the next step begins the construction of farm pond. Further the site selection and location of the pond in the selected site to be finished before the construction of pond starts. The selection of site and location of farm pond areas have been discussed in Chapter 3. In this chapter, discussion on methodologies for construction of farm pond including spillways, inlet and outlet structures, design of grassed waterways and embankment have been presented. As a guiding principle, the construction of farm pond involves the following steps:

8.2 Site Clearing

The area where the pond is to be constructed has to be inspected first. The site where pond has to be dug out should be cleared to an extent of about 10 m from all sides of top dimensions of the pond. All bushes, shrubs, stumps and other unwanted materials should be dug out and removed. If there are roots of plants, they should be uprooted. The land may be ploughed and harrowed, if necessary, to get a more or less even topography.

4.1 From Soil

Soil contains varied group of microorganisms such as fungi, bacteria, actinomycetes, algae and protozoa. The type of nutrients available, moisture, temperature and pH of the soil determine the nature of microbial population in soil. Different laboratory techniques for isolation of microorganisms have been detailed in chapter-III. These are used in particular for the isolation of specific type of microorganisms. All the techniques adopted are just to segregate the pathogens/ microorganisms from the mixture of microbial population present in nature.

(a) Isolation of Fungi

Soil contains large number of fungi and constitutes a major place of microbial population. They can be isolated in pure form by following the methods given below:

Generally microorganisms are so small and colourless in their natural state that it becomes difficult to observe them clearly under microscope. Stains and dyes, which are colouring agents, are used by biologist for better understanding of the morphological and anatomical structures of the organisms under study. Stains are prepared with great care and specification to get satisfactory result, while dyes are not as exacting in their characteristics.

Dyes are of two types, natural and synthetic. The natural dyes are used for histological purposes, whereas the synthetic dyes for bacterial stain. Usually dyes which are derivatives of cyclic compound benzene of benzole, are prepared from one or more substances found in coal-tar, and so are called coal-tar dyes. Chemically dyes are organic compounds containing both chromophore and auxochrome groups linked to benzene rings. Chromophore group provides the compounds the property of colour and thus benzene containing chromophores are called chromogens. It has no affinity to combine with fibres or tissue and as such not called dye. For being a dye, compound should contain an auxillary group which provides the compounds the properties of electrolytic dissociation.

The dyes may be acidic, basic or neutral. The acidic dyes are eosin, acid fuchsine and picric acid whereas the basic dyes are safranin, methylene blue, crystal violet etc. The acidic dyes ionize to give the dye portion of molecule a negative electrical charge. They are salts of sodium, potassium, calcium, magnesium etc. The basic dyes ionize to give the dye portion of molecule a positive electrical charge and are salts of chlorides, sulphates or acetates.

Introduction

Farming system is complicated inter-related with soil, plants, animals, implements, power, labour, capital and alternative inputs controlled partly by farming families and influenced to varied degrees by political, economic, institutional and social forces that operate at several levels. The farm is viewed during a holistic manner. The farmers are subjected to several socio-economic, biophysical, institutional, body and technological constraints. Farming system conceptually may be a set of components or parts that are reticulate that act amongst themselves. At the centre of the interaction is that the farmer exercise management and selection concerning the sort and results of interaction. It’s the human setting that gives ample condition for development and utilization of a specific system. A farming system clearly is incredibly complicated system. Therefore, any agricultural technology compatible to a specific agroecological state of affairs and socio-economic environment might not be adopted by alternative farmers. Unless each natural and human environment is thought-about, agricultural analysis won’t end in relevant agricultural technology. The income from cropping alone in tiny and marginal farms is hardly ample to sustain the farmers’ family. With the decline in farm size (0.15 ha) because of explosion of population, it’d be more and more tough to provide enough food for the family by the tip of the century. Therefore, the farmer, to be assured of an everyday income for a good living (above the poverty line), a considered mixture of anybody or additional of those enterprises with agronomic crops ought to complement the farm income and facilitate in usage the farm residue/waste. The choice of enterprises should be supported the cardinal principle of minimizing the competition and maximizing the complementarily between the enterprises.
