Since the Green Revolution of 1960s, Indian agriculture have been highly dependent on chemical fertilizers, exploitation of ground water for irrigation, intensive tillage etc. to raise the food grain production of the country towards ensuring food security for all. The consequences of these practices resulted in declined and degraded soil health, soil erosion and dried up water capillaries - ultimately posing threat to the sustainability of the future production. This invites the need of affordable changes in the agricultural practices without hampering the production. Conservation Agriculture, as put forward by FAO, is a set of sustainable agricultural practices, aims to conserve, improve and make efficient use of natural resources through management of soil, water and biological resources in aid with external inputs. The three basic principles of Conservation Agriculture include - minimum soil disturbances, permanent soil cover and crop rotation or crop diversification.

The present research had been conducted to study the Entrepreneurial behaviour of farmers in farmer producer organisations(FPO) in selected block of Odisha and in the end the comparison is made. The study had been conducted on 2 Farmer producer organisations (FPO) of Ranpur block from Nayagarh district of Odisha. A pilot study was conducted to understand the area,its people, institution ,communication and extension system of these states.

An exhaustive list of respondents was prepared critically with the help of FPO members. From the list, 100 respondents were selected for the study through Snowball sampling method. The primary data were collected with the help of structured interviewschedule by following the personal interview method. The secondary data werecollected from our departmental library, internet, Department of Agriculture, Odisha, Bidhan Chandra Krishi Viswavidyalaya ,etc.for establishing the conceptual framework of the study.

India is primarily an agriculture based economy, which implies, agriculture dominates the nation’s economic landscape. In the course of socioeconomic growth, agriculture is crucial. Around 58 per cent of the population in India relies only on agriculture for their livelihood. India is enriched with various agricultural and horticultural crops with diversified agro-climatic conditions and different soil types. India is one of the leading producing countries of cereals, pulses, oilseeds, fruits, vegetables etc. India is also have a prominent scope in allied sectors of agriculture includes livestock, poultry, forestry, sericulture etc. Among such crops, Moringa is the selected crop for this research study. Moringa (Moringa oleifera), which is popularly known as ‘Drumstick’ belongs to the family Moringaceae. Moringa is basically a native crop of India. This crop has its own therapeutic properties with greater nutritional content. Especially in South Indian cuisine, moringa pod is a highly regarded vegetable because of its distinctive flavour and fragrance.

7.1. Summary

The present research had been carried out to study the social ecology of arsenic contamination in groundwater; factors, perception and impact on life and livelihood of the selected village of West Bengal and in the end the comparison is made. The study had been conducted at village Mitrapur in the Haringhata block of West Bengal. A pilot study was conducted to understand the area, its people, institution, communication and extension system of these states.

An exhaustive list of respondents was prepared critically with the help of some villagers. From the list, 70 respondents from the village were selected for the study through a non-random snowball sampling method. The primary data were collected with the help of a structured interview schedule by following the personal interview method. The secondary data were collected from our departmental library, internet, Department of Agriculture, West Bengal, Bidhan Chandra Krishi Viswavidyalaya etc. for establishing the conceptual framework of the study.

Three types of Issues are Covered in this Study

• The influence of social, cultural, and/or economic variables on how drinking water poisoned with arsenic affects people’s life, notably their health (for example socio-economic patterns of illness and social),

• Social factors influencing people’s response: especially in relation to other priorities, perceptions of arsenic, and social roles and relationships.

The craniofacial region presents a unique challenge for implantable biomaterials because the pull of the craniofacial muscles produces variable loading in different regions. In addition, craniofacial skin loses elasticity with the age and develops subcutaneous tissue sags.

Even though surgeons are familiar with the use autogenous bone grafts for craniofacial reconstruction, the usage of alloplastic bone substitutes has increased continuously, because autogenous bone is difficult to harvest, time consuming, causes significant donor morbidity, and bone resorption, but most important thing is that the biocompatibility of current alloplastic materials are improving.

Synthetic substitute creates a new avenue for clinicians to explore as adjunct in surgical procedures. These materials may not necessarily be used solely for reconstructive procedures, but when used in the right situation in combination with autologous, allograft or other synthetic, the result have the potential for more desirable results.

a) A Key GDP Contributor: Dairy and Livestock sector form the backbone of agriculture with 28 per cent contribution in GDP and the progress in this sector is dependent on innovative measures to increase the value for farmers as well as customers.

b) Doubling Farmer’s Income : Doubling Farmer’s Income by 2022 can be achieved by improving crop and livestock productivity, efficiency to utilize resources, increased intensity of cultivation and diversification in high value cash crops, processing and value addition of food and animal products. This price realization can be assured through market reforms and efficient market linkages.

c) Unorganised sector – a challenge : The Indian dairy sector is still characterized by strong presence of unorganized sector. Apart from the Cooperative dairy sector, in the last few years there has been a considerable growth in Private Dairy sector and Milk Producers Organization like Maahi in Gujarat. If small dairy farmers are provided with sufficient ‘value addition’ training and support, they can increase their income considerably.

d) Value addition : Further, the milk processing plants can also go for value addition and innovation and in turn pay remunerative prices to milk producers.

The Asia-Pacific region, particularly the rural areas within CMCs, faces severe climate change impacts, including frequent natural disasters, rising temperatures, and sea-level rise, which threaten agriculture, livelihoods, and food security. Climate- resilient rural development (CRRD) is crucial for mitigating these vulnerabilities, addressing challenges such as agricultural dependency, limited infrastructure, governance gaps, financial constraints, and socio-cultural barriers. Key approaches like climate-smart agriculture, strengthened infrastructure, innovative start-up ecosystems, enhanced access to climate information, and inclusive policies empower rural communities to adapt and thrive. Stakeholders—governments, international organizations, the private sector, and local communities—play complementary roles in driving resilience through policy, funding, technology, and grassroots innovation. Sensitising all stakeholders across countries to mainstream climate change aspects and its impact on livelihoods, among all departments and the information dissemination by these departments to the public and relevant stakeholders regarding the climate change effects needs to be a continuous process.

Food preservation has evolved from traditional household practices to an interdisciplinary field incorporating microbiology, biochemistry, engineering, biotechnology, packaging, nanotechnology and digital intelligence. The book demonstrates that food stability can increasingly be achieved without excessive reliance on synthetic chemical preservatives. Effective preservation requires control of microbial growth, enzyme activity, oxidation, moisture, temperature and environmental exposure while protecting sensory and nutritional quality. Traditional practices remain scientifically valuable, while thermal, non-thermal, biological, packaging and digital technologies offer new possibilities. Future food systems will depend on carefully designed combinations of these approaches to improve safety, shelf life, sustainability, traceability and consumer acceptance while overcoming cost, regulatory and scalability challenges.

For looking into the biosafety in research laboratories, agriculture and other food producing industries it is important to look into the numerous strains of lactic acid bacteria that are associated with food systems and are capable of producing bacteriocin or antibacterial proteins with activity against foodborne pathogens such as Listeria monocytogens, Staphylococcus aureus and Clostridium botulinum. Recently considerable attention has been given on the identification of these proteins and their biochemical properties including spectrum of activity, production conditions, purification procedures, aminoacid composition and mode of action. Advances in genetic engineering have facilitated the characterization of proteins at genetic level, providing information about protein synthesis, structure and cloning of bacteriocin genes into other organism. One problem in the use of bacteriocin in their applications as bio-preservatives is the emergence of resistant population. The understanding on the mechanism of resistance to bacteriocins is limited which limits the application in biopreservation. Much of the work on bacteriocin has been done under controlled laboratory conditions without the presence of adventitious microbial population. More research is needed to determine the efficacy of bacteriocin producing organisms and bacteriocins which are stable under commercial conditions. Foodborne illness is a major international problem and an important cause of reduced economic growth. The contamination of the food supply with the pathogens and its persistence, growth, multiplication and/or toxin production

A sustainable and healthy food system is one which can provide food and nutrition security for all, in an economical way which is socially and environmentally sound for future generations. Underutilized indigenous and traditional crops can support and strengthen the existing food system, as they are in particular economical and friendly with the environment. Several underutilized indigenous and traditional crops are nutrient dense and adapted to marginal conditions, suggesting that they could be used to champion sustainable and resilient agriculture and food systems for smallholder farmers residing in these environments. The mainstreaming of underutilized indigenous and traditional crops and foods should be recognized for their attributes to make them desirable and to conserve them. In this regard, the fact that value chains for underutilized indigenous and traditional crops are poorly developed at present has created many opportunities to diversify the current food systems. This will create a new employment, market and distribution opportunities.It will also help to combat poverty. It will be if the smallholder farmers and women in rural areas are given the opportunity to utilize underutilized indigenous and traditional crops and re-enter the manistream system. A significant role which is played by the women for the production and conservation of underutilized indigenous and traditional crops offers opportunities for women empowerment through their inclusion in the food system. Promotion of gender equality and empowerment of women is directly linked for strengthening the sustainable food systems that can fight hunger and malnutrition and improve the lives and livelihoods of rural populations. The mainstreaming of underutilized indigenous and traditional crops into the food system would support women to diversify in a sustainable way, feed their own households and to provide nutritious food into the local markets. This will also help in addressing, the Sustainable

Mammary tumors are the most common type of neoplasia found in female dogs with high percentage of malignancy and rate of mortality. The rate of incidence of these mammary neoplasia and dysplasia is continuously advancing nationally and internationally over the last 45 years. There are different risk factors such as age, diet, hormonal exposure and breeds, which are required to be monitored in order to control the incidence of CMTs. In addition to conventional therapies such as surgical excision, radiotherapy and chemotherapy, additional precision therapeutic agents targeting TKIs, p53 tumor suppressor gene, cyclooxygenases, epithelial-mesenchymal transitions and various hormones/ hormonal receptors could be beneficial for the treatment of CMTs. Scientific efforts are also being made to develop different biomarker panels and tests for prognosis/diagnosis of the diseases as well as to develop vaccines against CMTs.

a) Transformation towards Commercial Agro: The poultry sector in India has experienced a revolutionary shift in structure and operation, which has led its transformation from a simple backyard activity to a major commercial agro based industry over a period of decades.
b) Layer Farming: The production of eggs has increased from 1.83 billion numbers in 1950-51 to 103.32 billion numbers in year 2018-19. The per capita availability reached at 79 eggs per annum in the year 2018-19 from 5 eggs per annum in year 1950-51. Andhra Pradesh, Tami Nadu and Telangana contributes about 55 percent share in total egg production.
c) Broiler Farming: Chicken meat contributes to 50 percent share in total meat production in year 2018-19 with the production of 4.06 million tonnes production. Broiler production is mainly concentrated in
Maharashtra, Haryana, West Bengal, Tamil Nadu and Andhra Pradesh. Broiler farming is mainly done through contract broiler farming. In that the integrator provides inputs such as chicks, feed, medicines and
vaccines. The contract farmer provides labour, shed, electricity, water, litter material, and other miscellaneous services or equipment that may be required. The integrator bears the transportation cost, investment and marketing risks. 

Concretions

Concretions are solid, compact mass of material, endogenous or exogenous in origin, found in tissues, body cavities, ducts or in hollow organs. Concretions are stone-like bodies commonly occur in urinary system, gall bladder and gastrointestinal tract. Concretions of endogenous origin are known as calculi while those formed from exogenous material are known as piliconcretion (Hair), phytoconcretion (plant fibres) and polyconcretion (polythenes).

Calculi

Calculi are formed due to deposition of salts around the nucleus/nidus consisting of either fibrin, mucus, desquamated epithelial cells or clumps of bacteria. Due to the gradual and repeated precipitation of salts, calculi become laminated. In the process of calculi formation, the inner structural arrangement gets shrink, producing a rough superficial surface. Calculi formation is more common in urinary system and in gall bladder of man and animals; however, they may also occur in salivary gland, pancreas and intestines.

Introduction
Storage of fresh meat without microbiological degeneration at temperature more than freezing point of meat is known as ‘conditioning’ or ‘ageing’ and it is said to enhance tenderness and flavor of the meat Conditioning is also known as ageing or proteolysis of meat
• In the initial 24–36 h after the slaughter, glycolysis is the prevailing reaction going on during post-mortem
• The organization of the contractile proteins can only be conserved by the constant supply of ATP (energy source)
• But ATP supply becomes scarce with the passage of time after death and denaturation of the proteins starts
• Denaturation is a physical or intramolecular reorganization without involving hydrolysis of the bonds occurring between the various amino acids of the polypeptide proteins chains
• Denaturation is characterized by heightened reactivity of different chemical groups, a modification in molecules shape or size, reduced solubility and lost biological reactivity in cases of enzymes or hormones
• In the course of post-mortem conditioning, proteins are prone for denaturation due to lower pH than in-vivo, temperatures more than 25 °C or less than 0 °C, dehydration and higher non- hysiological salt levels
• Connective tissue proteins such as collagen and elastin do not undergo denaturation during conditioning

Various physical, chemical and biological factors interdependently affect the fungal colonization or production of the mycotoxin. Physical factors such as temperature, relative humidity and insect infestations create ideal environment for fungal colonization and mycotoxin production. Stresses such as drought, an increase in temperature, and an increase in relative humidity may selectively alter colonization and metabolism of mycotoxigenic fungi and thus alter mycotoxin production (Russell et al., 1991). Cool and damp weather favours the germination of the sclerotia and thus ergot alkaloid formation in fescue and ryegrass.

Biological factors are categorized into intrinsic factor such as fungal species, strain specificity, strain variation and instability of toxigenic properties. Interaction between the toxigenic fungal species and substrate affect the fungal colonization and mycotoxin production. Some plant species are more susceptible to colonization and some resistant plant species may also get infestation due to favourable environmental conditions.

Introduction

In recent years, there has been an exponential increase in the volume of datasets generated across various application domains. However, a prevalent issue within these datasets is class imbalance, wherein the distribution of samples is biased towards the major class, resulting in an extremely skewed dataset. Number of samples in the major class far exceeds those in the minor class, sometimes with an extreme ratio like 1/1000 or even higher. While traditional machine learning models trained on such imbalanced datasets often yield high accuracy for the overall dataset and the major class samples, their ability to correctly predict class labels for minor class samples is signicantly compromised. In many real-world scenarios, the minor class samples hold greater signicance and importance compared to the major class samples. Therefore, researchers are increasingly focusing on addressing the challenges posed by class imbalanced datasets and exploring solutions to improve the performance of machine learning models in handling such imbalances

7.1 Conducive Soils

Without a conducive environment, plant disease does not occur. Soils that favour the disease/ and the pathogen are generally referred to as conducive soils. Inoculum of powdery scab is the either the spore ball (an aggregation of thick walled, tough, resting spores, comprising an average of 700 spores) or the swimming spore (zoospore) that each spore of the spore ball releases. Spore balls of powdery scab have been shown to persist for long periods (Brierley et al., 2008). Exactly, how long they can survive has not been fully determined, but experimentally and anecdotally, it is much longer than a typical rotation. Inoculum may be seed-borne or soil-borne and whatever the source spore balls are able to cause infection and disease. Seed tubers may carry spore balls within powdery scab lesions or may carry spore balls symptomlessly where they have been picked up from adjacent infected tubers or contaminated machinery (e.g. on grading lines). In addition, recently, it has been found that tubers may be latently infected. That is where tubers are infected but symptoms are not expressed. Latent infections may be associated with conditions that are unfavourable for disease development, such as sub-optimal temperatures.

i. Soil Moisture: A high soil moisture content both encourages swimming spore release and facilitates movement to the host. It is generally accepted that swimming spores are unable to move through the soil without free water within the soil matrix (i.e. soil saturation). Many studies confirm the importance of free water in soil as a requirement for infection. The occurrence of wet soil conditions prior to tuber initiation, enabling inoculum multiplication, has been cited as important for high levels of powdery scab. Alternatively, prolonged wet soil conditions after tuber initiation can lead to high levels. In experiments investigating soil moisture, there is disagreement over the importance of constant versus fluctuating soil moisture conditions in powdery scab development. However, it is difficult to make clear comparisons because soil moisture levels have not always been measured and factors that may affect disease development (e.g. soil type, initial inoculum level) will have differed from experiment to experiment. Some studies have shown that constant high soil moisture has suppressed powdery scab development possibly due to low oxygen/high carbon dioxide levels rendering swimming spores inactive.

When a fixed voltage is applied to two electrodes dipping into a solution,a current will flow, depending on the conductivity of the solution. Conductivity measurements do not give information about the nature of the ions in solution. However, they are useful in the quantitative measurement of the ions.

Introduction 
Polymers are mostly distinguished from metals by their property of inability to conduct electricity. Because of the insulating properties, polymers find advantages for many applications of plastics. However with the discovery of poly sulphur nitride [(SN)x], which acts as super-conductor at low temperature the evolution of conducting polymers began in 1975. After two years the linear conjugated organic polymer polyacetylene treated with gaseous bromine or Iodine found to have metallic properties. Some examples of conducting polymers are polyaniline, polypyrrole and polythiophene etc. Conducting polymers are organic polymer, possesses the magnetic, electronic, electrical properties, mechanical properties, and processibility etc. These properties are most commonly related to the conventional polymer. The transformation of polymer from insulator to conductor is called doping. For example: the effect of conductivity due to the absorption of I2 into polyacetylene is analogous to the effect of doping of arsenic, boron, and phosphorus into silicon to make semiconductor. Doping and undoping can be achieved in conducting polymers by an alternate route of electrochemical oxidation and reduction. Doping includes either the removal of electrons from or addition of electron to the conjugated backbone of conducting polymers. Doping is therefore of two types: Oxidative doping (p-type): In this case, the polymer backbone carries a positive charge due to removal of an electron by ordinary oxidation. Examples of p-doped conductive polymers are polyacetylene, polyaniline, polypyrroles etc. The p-doping causes oxidation of the polymer backbone to form cations. When these cations move along the polymer backbone in an electrical field, the polymer is electrically conductive. Reductive doping (n-type): the polymer backbone acquires negative charge by receiving electrons. Ex: Polyacetylene can be n-doped by alkali metals but these are less explored because they are very much sensitive towards atmospheric air than specific undoped type polymer. According to the principle of electroneutrality, doped conducting polymer needs counter ion to balance the opposite charges in the polymer backbone. These counterions are called dopant. Some common examples of dopants are usually small anions e.g. Cl-, I-, and SO4 2-. However poly-electrolyte like p-toluene sulphonic acid can act as the dopant. The process by which the doped polymer loses its charges and becomes an insulator is called undoping. For a doped conducting polymer with isolated small anions as dopants, undoping is accompanied by the loss of the dopant. Undoping causes the conductive polymer to lose its electrical conductivity and useful optical properties.

Review of literature or consulting of literature is just beginning of a research project. The main intellectual work is to study the previous work meticulously and to draw conclusions regarding existing problems. This leads us to another intelligent part of the research i.e. planning of the research work. If you analyze what you are planning, it is only about materials to be employed and methodology of the research work (with planning of the work)- only these three parameters are under your control as results will be the outcome of these three facets while discussion will be how you consider your results in presence of previous research work. In fact, this statement of mine is more align to the sermon of “Shrimad Bhagwat Geeta” (5) where it is stated that man has control only on his actions (planning and conducting research) hence fulfill this duty without caring for the results-which in turn will depend on your analyzing the previous facts and how you have planned to solve the problem. Therefore, pay full attention on these three facts of the research.

Proximate analysis of the feeds and fodders does not give any idea about their nutritive value, because availability of nutrients varies according to the feed stuffs. The major loss of nutrients take place in body after ingestion of feed is through feces. Hence, it is very essential to know the actual amount of feed digested by the animals. Losses which take place after digestion are more or less comparable in different feedstuffs.

Digestibility
Digestibility of a feed can be defined as that proportion of feed which is not being excreted in the faeces and hence assumed to be absorbed by the animal. It is expressed as percentage (% digestibility or digestibility coefficient).

Digestion trial requires feaces collection only but when we have to go for balance studies we have to collect urine also (in addition to the nutrient losses take place through milk in lactating animals) to find out the nutrient losses takes place through urine. As we have discussed in digestion trial also, male animals are usually preferred to perform these types of studies to obtain contamination free urine and feaces to find out clear picture.

Balance studies are usually performed to find out the balance of nitrogen (Nitrogen retention, NR) and minerals (Ca, P etc.) as urine is rich in these nutrients and hence for their balance we have to find out the losses takes place through urine.

Confectionery fills an especially direct need; the sugar of agreeableness joined with exquisite flavors, smells and mouthfeel affects a basically transitory feeling of thriving and joy. Sugar confectionery has been made all through the long haul with extending headway and it remain alive in unlimited plans following a changed levels of agreeableness, flavors just as scents, feel, appearance and tastes

Sugar confectionery and chocolate includes candies (sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of sugar confections. The words candy (US and Canada), sweets (UK and Ireland), and lollies (Australia and New Zealand) are common words for the most common varieties of sugar confectionery. Confectionery depends on numerous ingredients which have been discussed in detailed in this chapter

Conference

A conference is a formal gathering where people come together to discuss, exchange ideas, present research and engage in discussions on specific topics or fields of interest. These gatherings can vary widely in scale, purpose and format, bringing together professionals, researchers, academics, industry experts, or enthusiasts.

Audio conferencing

Its also called Teleconference, which means meeting a group or party via a phone call instead of meeting them physically. In most cases, standard telephone lines and speakerphones are employed. The person who starts the audio conference called the calling party and the people who are attending the calls are known as participants. Technology requirement of the audio conference:

1. Phone/Computer with access to internet connection
2. Speakers
3. Microphone

Conflict represents an inevitable and potentially constructive dimension of community mobilization that emerges when individuals and groups with different interests, values, perspectives, or needs interact in pursuit of shared or competing goals. Rather than viewing conflict as purely destructive or problematic, effective community mobilization requires sophisticated understanding of conflict dynamics and skilled application of management strategies that can transform disagreements into opportunities for learning, innovation, and strengthened relationships that enhance collective capacity and democratic participation. The complexity of contemporary community challenges requires bringing together diverse stakeholders with varying backgrounds, experiences, priorities, and approaches to problem-solving, creating natural conditions for disagreement and tension that must be navigated skillfully to maintain group cohesion while harnessing the creative potential that emerges from diverse perspectives and approaches. Understa

Abstract

Whenever human beings come together and interact, there are bound to be conflicts. It is the struggle between individuals or groups or organizations for values, status, power or scare resources, that creates tension and frustration. It cannot be totally eliminated, it has to be managed. Positive conflicts sometimes lead to innovations or new directions of thinking in the Research and Development (R&D) environment. But negative conflicts mainly breed unproductiveness, a climate of distrust and suspicion, antagonism, and neglect of organizational goals. Conflict arises due to one of the three reasons : unacceptability, uncertainty and incomparability of alternatives. The problem of unacceptability arises when the most preferred alternative is not found to be acceptable. Uncertainty arises when the individual faces problem to select one from the alternatives. The incomparability dilemma is a situation where the decision maker does not have standards to compare alternatives. Modern managers must be equipped to deal with different types of conflict and devise strategies to resolve them. This chapter deals with conflicts at individual level, at group level or at organizational level, their resolution through negotiation or collaboration, models and methods for managing conflicts, etc in details. A healthy organization climate can unblock creative potential of its employees, streamlining and facilitating efforts for the good of the organization and its employees.

A conflict is a fight or a clash of interest, opinion, or even principles. Conflict can never be eliminated from the society; as there are different reasons of conflict. It may vary from personal, racial, class, caste, political, international and many more.

Conflict in a group often follows a specific course. Routine group interaction is first disrupted by an initial conflict within the group. It is often caused by internal differences of opinion, disagreements between its members, or scarcity of resources available to the group. Some of the common sorts of conflicts are:

• Inter-group conflict is conflict between two or more groups.
• Organization conflict is discord caused by opposition of needs, values, and interests between people working together.
• Role conflict involves incompatible demands placed upon a person in a manner that makes accomplishing both troublesome.
• Social conflict is the struggle for supremacy or autonomy between social classes.
• Conflict of interest is involvement in multiple interests which could possibly corrupt the motivation or decision-making.

Confocal microscopy is a powerful tool that creates sharp images of a specimen that would otherwise appear blurred when viewed under a conventional microscope. This is achieved by excluding most of the light from the specimen that is not from the microscope’s focal plane.The image thus obtained has less haze and better contrast than that of a conventional microscope and represents a thin cross-section of the specimen. Laser scanning confocal microscopy has become an invaluable tool for imaging thin optical sections in living and fixed specimens ranging in thickness up to 100 micrometers. In fact the confocal microscope is often capable of revealing the presence of single molecule.
The modern confocal microscopes can be considered as completely integrated electronic systems, where the optical microscope plays a central role in a configuration that consists of one or more electronic detectors, a computer (for image display, processing, output, and storage) and several laser systems combined with wave length selection devices and a beam scanning assembly. In most advanced systems, integration between the various components is so through that the entire confocal microscope is often collectively referred to as a digital or video imaging, capable of producing electronic images.
Principle
Current instruments are highly modified from the earliest versions, but the principle of confocal imaging that was developed by Marvin Minsky is employed in all modern confocal microscopes. The image in a confocal microscope is achieved by scanning one or more focused beams of light, usually from a laser or arc-discharge source, across the specimen. This point of illumination is brought to focus in the specimen by the objective lens and laterally scanned using some form of scanning device under computer control. The sequences of points of light from the specimen are detected by a photomultiplier tube (PMT) through a pinhole (or in some cases, a slit) and the output from the

The difficulty in conducting a factorial experiment in an RBD is that, as the number of factors and/ or that of levels of the factors increase, the number of treatment combinations to be compared increases too. This in turn necessitates use of large sized blocks to accommodate all the treatment combinations i.e in a 2^4 – experiment there should be 16 plots in a block. But it has been found that the experimental error increases with an increase in the size of a block, for then it becomes less effective in controlling the heterogeneity of the units. A remedy has been found out : this is to divide a replicate (a complete block) into a number of equal blocks (incomplete blocks) and then to allocate the treatment combinations to these blocks so that only the unimportant treatment comparisons gets mixed up or entangled with the block comparisons. These treatment comparisons are then said to be confounded or mixed up with block effects. These effects cannot be separately tested or estimated. But the remaining treatment effects, which are not confounded with the block effects, are still capable of separate estimation and testing.

Congenital anomaly of newborn buffalo calves is quite common in new born calves. Most common encountered are atresia ani, rectovaginal fistula etc. Sometimes, developmental defects interfere with physiological processes viz. in urination and defecation. Therefore, such cases, if not corrected well in time can cause death of the patient. In the present report, few newborn calves were brought to the veterinary clinic with the following abnormalities:

Agenesis of Urogenital System Without Anus

Five newborn buffalo calves were brought to the veterinary clinic with the complain of not passing urine and feces. There was no visible external genitalia and anal opening. At the site of vulva, there was only an impression of vulvar lips and below it, a cord like structure was hanging.

There was an impression of round structure below the skin; in some cases it was outside giving appearance of scrotum which was located in between the two thighs. On ventral side of abdomen, preputial sheath was not present, therefore, it was very difficult to decide about the sex of the calves and site of external preputial-orifice. There was an indication of both sexes, but organs were not developed, therefore it was difficult to decide about the sex of the calves. In some cases, impression of the anal sphincter was visible but there was no visible external anal opening. There was slight deviation of the tail from its base also. Intake of milk was normal. Abdomen was distended bilaterally. Respiratory rate was higher than the normal with slight discomfort .Heart rate was elevated. Blood picture revealed increased total blood cell count with neutrophilia. Radiography of the abdomen showed distended urinary bladder at the floor of pelvis indicating formation of the urogenital system without development of the external opening. Barium meal study revealed marking of gastrointestinal tract and stagnation of the barium up to the rectum.

Product Development and Marketing

Several efforts are being made on the research front for development of novel products from fish which have enhanced shelf life, retain the freshness and nutrients and are safe to consume. During the course of product development, which are in many stages, studies are conducted prior to commercialisation to ensure the acceptance of a product.

In a business, understanding consumer behaviour plays an important role in success. To be in a business for a long time, it is essential to know what the consumer prefers and why. Consumers make the buying decisions based on a number of factors. The purpose behind studying the buying behaviour and consumer preference is to produce and market products which may better meet the needs of a consumer. The emerging fastfood culture among the young and affordable has brought focus on processed food and its demand in the domestic food market in India. Domestically, spending on food and food products constitutes the largest portion of the Indian consumer’s spending – more than a 31% share of wallet. Evaluation of consumer preferences before introducing a new product will help the marketer to refine the product for better reach.

Conjoint Analysis

Conjoint analysis is a popular technique used in marketing research to study the features a product that should possess to have a wide consumer reach. Conjoint analysis was initially conceptualised by Luce and Tukey (1964) and further developed by Green and Rao (1971) for marketing research. It employs a decompositional method to estimate the structure of consumer preferences and consumer utility values of different attributes of a product or service. It is a decompositional method that disaggregates the structure of consumer preferences into utility values. The relative importance of a product can also be estimated using this method.

1. INTRODUCTION

The concept of product management in market research is all about tradeoffs. Whether the objective is to increase market share, profit margin or revenue, every product manager makes trade-offs—quality vs. cost, time to market vs. breadth of features, richness of the offering vs. ease of use, etc. So, how does anybody know what the market wants? What market segments exist? What those segments prefer? What will they pay? or what trade-offs to make? The answer is to get the market to make the trade-offs. The conjoint analysis is the tool to measure the trade-off i.e. to understand customer preferences, values and choices. Conjoint analysis is used for many marketing decisions, including new product development process, selecting among alternative product designs, targeting, and pricing. It is also used to predict their choices for future products and services. Conjoint Analysis assumes that a product can be “broken down” into its component attributes. For example, a car has attributes such as colour, price, size, miles-per-gallon, and model style. Using Conjoint Analysis, the value that individuals place on any product is equivalent to the sum of the utility they derive from all the attributes making up a product. Further, it assumes that the preference for a product and the likelihood to purchase it are in proportion to the utility an individual gains from the product. It is generally inappropriate for products which are evaluated by consumers on the basis of their “image”, such as beer or cigarettes, rather than on the basis of their constituent attributes. It is so widely used in market research that helps to understand the market’s preferences including product development, competitive positioning, pricing, product line analysis, segmentation and resource allocation.That gives the better insight to the market revenue, share, profit which in turn helps to provide the better market intelligence. The present chapter deals with the genesis, usefulness and analysis procedure of conjoint analysis in different software with example.

Abstract

Dual inoculation of Rhizobium + VAM coupled with recommended NPK doses was found to produce the highest bean pod (6.38, 6.40 qha-1) and straw (35.11,35.35 qha-1) dry matter production and resulted in higher macro and micronutrient contents in bean leaves which were to the tune of 4.05, 4.06%N,0.44, 0.49 %P, 2.65, 2.66 %K, 2.65, 2.67%Ca, 64.67, 64.59 ppm Zn, 242, 242.2 ppm Fe, and 36, 36.33 ppm Mn. Under this treatment increase in bean pod and straw dry matter production during the years 2002 and 2003 was to the tune of 130, 131 and 81, 83 per cent, respectively over control.

Introduction

Genetic variability is essential for the evolutionary success of all organisms. In diploid eukaryotic the processes of crossing over exchange of genetic material between homologous chromosomes and meiosis contributes to his variability. In haploid, asexually reproducing prokaryotic organisms, genetic recombination may occur by conjugation transduction, and transformation. In this experiment only the process of conjugation is considered.

Conjugation is a matting process during which a one direction transfer of genetic material occurs at physical contact between two sexually differentiated cell types. This differentiation or existence of different mating strains in some bacteria, is determined by the presence of a fertility factor of F factor, within the cell. Cells that lack the F factor are recipients (females) of the genetic material during conjugation and are designated as F^- . cells possessing the F factor have ability to act as genetic donors (males)during the mating. If this F factor is extra chromosomal (a Plasmid or episome), the cells are designated as F⁺; most commonly only the F factor is transferred during conjugation. If this factor becomes incorporated into the bacterial chromosome there is a transfer of chromosomal genes, although generally not involving the entire chromosome or the F factor. The resulting cells are designated as Hfr, for high frequency recombinants.

India is one of the few countries in the world, which has contributed richly to the international livestock gene pool. Small animal particularly sheep and goat biodiversity in India is characterized by high degree of endemism in different agro climatic regions, and has led to the development of various breeds/strains that are well adapted to specific set of environmental conditions. These breeds have generally been named after their place of origin and some based on their prominent characteristics. Indigenous sheep and goat contribute greatly to the agrarian economy, especially in areas where crop and dairy farming are not economical, and play an important role in the livelihood of a large proportion of small and marginal farmers and landless laborers. Sheep and Goat rearing and production has been the important source for sustainable livelihood of the rural people mainly in arid, semi-arid and temperate regions of India as it serves their various needs and provides an unceasing source of income round the year.

Introduction

There is a widespread degradation of natural resource, e.g., soil erosion, nutrient loss, water-logging, salinity, alkalinity, acidity, decline in soil organic carbon (SOC) content, ground water depletion and micronutrient depletion. The major causes are washing away of topsoil and organic matter due to water erosion, intensive deep tillage and inversion tillage, dismally low levels of fertilizer application, mining and other commercial activities, faulty agricultural practices, no or low use of organics, indiscriminate use of herbicides, pesticides, fungicides etc. Other cause is loss of organic matter with higher temperatures, which increase rate of microbial decomposition of organic matter due to adverse effect of climate change. Climate change due to global warming as a result of increased concentration of GHGs in the atmosphere is a well-established fact. Impacts of climate change are experienced throughout the world. Increases in global mean temperature, rise in sea-level, and occurrence of extreme events are the consequences of climate change. These changes may deplete the SOC pool and soil structural stability, increase soil’s susceptibility to water runoff and erosion, disrupt cycles of water, carbon, nitrogen, phosphorus, sulphur and other elements, and cause adverse impacts on biomass productivity, biodiversity and the environment. Climate change is likely to have a variety of impacts on soil quality. In order to restore soil quality, enhance productivity, it is of utmost importance to focus on conservation agriculture practices on long-term basis. Conservation Agriculture (CA) is gaining importance as an alternative to conventional agriculture.

Introduction

The Indo-Gangetic Plain is one of the world’s major foodgrain producing regions. The Indian states falling under this region, viz. Punjab, Haryana, Uttar Pradesh, Himachal Pradesh, Bihar and West Bengal, are also the major rice-wheat growing states spread over 10.5 million hectares in the country. During the past 30 years, agricultural production growth in this region has been able to keep pace with population demand for food in the country mainly due to adoption of green revolution technologies inducing yield growth, followed by area expansion. But this opportunity is ceasing very fast due to limited scope for increasing the availability of arable land and natural resources. The other issue is the conservation of the basic resources of land and water for sustainability of agriculture in the Indo-Gangetic Plain. It is generally believed that the rice-wheat system has strained the natural resources in this region and more inputs are required to attain the same yield levels (Swarup and Singh, 1989; Kumar and Yadav, 1993; Lal et al., 2004). It is, therefore, imperative now to promote alternative technologies that would help conserve the much needed but gradually depleting natural resources while boosting productivity growth in the long-run by maintaining soil health and production environment. As a part of this strategy, conservation agriculture and resource conserving technologies play a major role in sustaining and enhancing the productivity of the rice-wheat system at a lower cost of production.

Conservation agriculture (CA) has potential to changes soil physical, chemical and biological soil quality parameters compared to conventional tillage (CT) systems. CA can also affect the functional diversity of soil microbes that essential for improved soil quality, crop production and many ecosystem services.

Conservation Agriculture is a farming system that promotes minimum soil disturbance (i.e. no tillage), maintenance of a permanent soil cover, and diversification of plant species. It enhances biodiversity and natural biological processes above and below the ground surface, which contribute to increased water and nutrient use efficiency and to improved and sustained crop production.

Three principles of Conservation Agriculture

Introduction

Intensive soil tillage, burning of crop residues and over use of fertilizer and irrigation water under current agricultural practices has accelerated the pace of degradation in Indian agriculture. Intensive soil tillage increases soil erosion and nutrient runoff into nearby waterways. Crop residue burning resulting in loss of plant nutrients and release of greenhouse gases (GHGs) in the atmosphere. Imbalanced use of chemical fertilizer leads to soil compaction, slows down the fertilizer utilization rate and contaminates the local environment. Increasing demand of irrigation water causes water shortage and harms the environment in several ways including increased salinity, nutrient pollution, and the degradation of flood plains and wetlands. In the face of these management and environmental challenges, there is a need to formulate such agricultural practices which improve the productivity of natural resources as well as of external inputs and help to prevent soil degradation. Conservation agriculture (CA) practices such as reduced tillage, residue retention and proper crop rotations offer such solutions. CA also helps in making agricultural systems more resilient to climate change and safeguard ecosystem services.

Introduction

India agriculture is now at turning point as we have travelled a long way after the advent of green revolution. Over the past four to five decades our strategies, policies and actions were guided by goals of ‘self-sufficiency’ in foodgrains production via green revolution. Indian agriculture has been successful in achieving increased food grains production albeit at a low level of satisfaction. While the mission of increasing foodgrains production stands somehow achieved, these gains were accompanied by widespread problems of resource degradation and high factor productivity, which now pose a serious challenge to the continued ability to meet the demand of an increasing population and lifting our people above the poverty line (Tan et al., 2010). Indian agriculture has reached a point where it must seek new directions – those by way of strategies, policies and actions which must be adopted to move forward addressing sustainable intensifications. The past strategies to increase food grains production, however, have resulted in massive exploitation of natural resources, contributing to unsustainable growth; there is need to change this approach in the future. This will call for strategies, which are different than the ones we adopted in the ‘green revolution’ era. High levels of fertilizer use and decreasing resource use-efficiency are increasingly contributing to groundwater pollution and increased emissions of green-house gases (GHGs) (Gupta, 2004). High level uses of pesticides in many areas have become a major health hazard. Thus, with continuously deteriorating resources, widespread problem of soil and water contamination and eroding ecological foundation, sustainability of agriculture is becoming highly questionable (Conway and Barbier, 1990). There is need to seriously debate on the strategies required to ensure that agriculture continues to play a critical role in the overall development.

Introduction

The challenge of increased food production to meet food security needs still persists 50 years after the start of the Green Revolution as population growth continues to increase in many developing countries. There appears to be no alternative but to increase agricultural productivity and the associated individual factor productivities (such as water, labor, nutrients, energy and capital) to meet the food demand by 2050 and to alleviate poverty and hunger. Thus, needs technological initiatives for further agricultural intensification. But already happening negative effect of crop production intensification on essential natural resources such as soil, water, biodiversity, and associated ecosystem services has forced agriculture stakeholders to search for novel initiatives that focus on sustainable production optimization rather than just intensification. Furthermore increased food supply is a necessity though not sufficient for eliminating hunger and poverty. What is important is who produces the food, has access to the technology and knowledge to produce it, and has the purchasing power to acquire it. Of the developing world’s 5.5 billion people, 3 billion live in rural areas – nearly half of humanity. Of these rural inhabitants, an estimated 2.5 billion are in households involved in agriculture, and 1.5 billion are in smallholder households (World Bank, 2008 and Herren, 2010). Poor farmers need low-cost and readily available technologies and practices to increase local food production and to raise their income. At the same time, land and water degradation is increasingly posing a threat to food security and the livelihoods of rural people who generally live on degradation-prone lands. There are several other key issues while relating the situation to Indian context.

Conservation agriculture is an approach to managing agroecosystems for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. Food and Agriculture Organisation of the United Nations (FAO) defines conservation agriculture as a farming system that promotes maintenance of a permanent soil cover, minimum soil disturbance (i.e., no tillage), and diversification of plant species.

Conservation agriculture (CA) defined as minimal soil disturbance (no-till) and permanent soil cover (mulch) combined with rotations is a recent agricultural management system that is gaining popularity in many parts of the world. Cultivation is defined by the Oxford English dictionary as “the tilling of land”, “the raising of a crop by tillage” or “to loosen or break up soil”. Other terms used in this dictionary include “improvement or increase in (soil) fertility”. All these definitions indicate that cultivation is synonymous with tillage or ploughing.

The other important definition that has been debated and defined in many papers is the word “sustainable”. The Oxford dictionary defines this term as “capable of being borne or endured, upheld, defended, maintainable”. Something that is sustained is “kept up without intermission or flagging, maintained over a long period”. This is an important concept in today’s agriculture since the human race will not want to compromise the ability of its future offspring to produce their food needs by damaging the natural resources used to feed the population today.

8.1 Introduction

Conservation agriculture (CA) is an approach to regenerative agriculture and land management practices based on three interlinked principles: (1) continuous minimum mechanical soil disturbance using no-tillage or reduced tillage based crop cultivation, (2) maintenance of permanent soil cover using crop residues and cover crops and (3) diversification of cropping system using economically, environmentally and socially adapted crop rotation including legume crops and cover crops coupled with other complementary agronomic management practices (FAO, 2014).

Introduction

The Indian agriculture is very complex and carrying out multi-functionalities of providing food, nutrition and ecological security besides employment and livelihood for over 700 million people. Indeed, India has made a marvelous achievement in attaining self-sufficiency in food grain production after the induction of Green Revolution which eventually resulted in maintaining all-time high buffer stock in warehouses of our country. Such rosy picture in production trends turned to be bleak in the past few years. There are various reasons behind this. Shrinking resources of prime lands, deforestation and accelerated erosion, deterioration of soil physical environment, increasing waterlogging and salinity in canal irrigated areas, declining water table in well-irrigated areas, poor management of rainwater, lower efficiency of inputs such as water, fertilizers and agrochemicals, rapid industrialization coupled with pollution and environmental degradation and hazards have aggravated the problem. At the same time, increase in atmospheric concentrations of greenhouse gasses (GHG), of which the most common is carbon dioxide (CO₂), is the primary cause of global warming and the Intergovernmental Panel on Climate change (IPCC) estimates that the current greenhouse gases (GHGs) concentrations are 30% more than the pre-industrial level. C is accumulating in the atmosphere at a rate of 3.5 Pg (Pg = 1015 g or billion tons) per annum, the largest proportion of which resulting from the burning of fossil fuels and the conversion of tropical forests to agricultural production. Under such circumstance, there is an imperative need to produce more from less arable land and water through meticulous management of basic agricultural resources such as soil, water and biological inputs.

Introduction

The green revolution is exemplified by too much adoption of high soil disturbance, modern varieties, energy exhaustive technologies, high amount of capital investment and simplification of farming systems (Meeus, 1993), resulting in uniform and featureless landscapes (Nassauer and Westmacott, 1987) in the most intensively farmed arable areas. In post-green revolution epoch, we had experienced a period of remarkable escalation in food productivity, despite rising land values and increasing land scarcity. Farmers from both developing and developed countries get exposed to several production constraints for achieving a sustainable, cost-effective and assured return from their field. Depending upon the circumstances and the scale of farm activities, farmers face varying degrees of climate risk, biotic invasion, and economic uncertainty. Thus, from the context of economical ambiguities, volatile food prices, social pressure to buffer ups and downs of agricultural production and achieving food security for ever growing population and curtailing poverty, farmers must be equipped with novel cultural practices to achieve a sustainable and assured cost-effective grain production. Research experiments throughout the globe found that the principal indicators for unsustainability of agricultural systems are: (1) intensive tillage induced decrement of soil organic matter (OM), structural degradation of soil, accelerated water and wind erosion, reduced water infiltration rates, surface sealing and crusting, soil compaction, (2) insufficient return of organic materials into soil, and (3) monocropping.
