Observation recording: To record the observation on seed germination, Pollination and dispersal needs to conduct frequent field visits in different seasons for recording the various pollination and dispersing agents and conducting experiment on seed germination.

Observation recording: To record the response of various tree species to produce root sucker, coppicing, pollarding, pruning and browsing of various tropical tree species requires field visits and conducting experiment to observe which species is producing root suckers, coppice etc.

Observation recording: To record the response of various tree species to the light, fire, drought, frost and wind, frequent visits of the forest areas which are affected by fire, drought and frost should be conducted. Studies relevant to light requirement in various growth stages of tree and ability to stand against various intensities wind are very lengthy that requires long time periodic studies.

Observation recording: To record the response of various tree species to the light, fire, drought, frost and wind, frequent visits of the forest areas which are affected by fire, drought and frost should be conducted. Studies relevant to light requirement in various growth stages of tree and ability to stand against various intensities wind are very lengthy that requires long time periodic studies.

Observation recording: Today green felling is completely banned. Fuelwood species are managed under clear-felling systems and tree species infected by insects and pests are felled selectively. The students are advised to visit the fuelwood plantations and forests areas where selective felling is going on.

In manipulation of plant development, training and pruning are important for which our knowledge about plant development and its phenology has to be complete. These practices are important in fruit crops.

Introduction

The wild seedling of walnut has been found growing in west regions right from the Carpathian Mountains in Eastern Europe across Turkey, Iraq, Iran, Southern USSR and Afghanistan to the North-Western Himalayas. It is believed to have originated in Iran and the areas surrounding it. The Returning army of Alexander brought it to Europe from Iran. Almost all parts of the walnut tree are utilized. The fruit has excellent flavour and is mainly consumed as a dried fruit, eaten for table purposes. The kernels contain about 60–75% fat and oil, 16% carbohydrate, and 15% protein. Jammu and Kashmir is the largest walnut producing state in India and the USA is a leading producer of walnuts.

Weather and climate have profound influence on agriculture of a region. There are some differences between these two terms. Weather describes the state of the lower atmosphere of a place with respect to temperature, precipitation, wind direction, wind speed, humidity, cloudiness and pressure etc. over a short period of time. The short term variations over minutes to days are indicated as weather of a location. It says whether the atmosphere is hot or cold, rainy or dry, sunny or cloudy, still or cyclonic and so on usually for period of 24 hours. The weather may vary from place to place and from time to time due to difference in temperature, cloudiness, humidity, rain and other events of atmosphere. It may be sunny at one locality, but rainy at another locality.

Introduction

The fruit is a hard-shelled, many-seeded berry with its pinkish brown, aromatic sour and sweet pulp being the edible portion of the seeds embedded in it. The tree is one of the hardy trees of arid and semi-arid regions.

Principle

β-Glucosidase (BG) plays a major role in the degradation of soil organic matter and plant residues. It catalyzes the hydrolysis of β-d-glucopyranosides, the final, rate-limiting step in the degradation of cellulose, the most abundant polysaccharide providing simple sugars for the soil microbial population. BG has been shown to be sensitive to changes in soil and residue management as well as an early indicator of changes in SOC before these changes are reflected in total or organic C analyses. The method is based on colorimetric determination of the p-nirtrophenol released by β-glucosidase when soil is incubated with buffered PNG solution and toluene.

Introduction

Resources must be managed effectively to achieve maximum sustainable agricultural production from limited natural resources. Many of the resources that agriculture depends on (such as water and land) are finite and need to be well managed for long term sustainability. In most cases, this means avoiding adverse effects on the society and environment. With the development of agricultural sectors, the utilization patterns of natural resources in agriculture are important concern for policy makers in present climate change scenario. Unlike other production activities, agricultural activities also utilize factor resources to produce several marketable products or services. The way the natural resources are utilized in agriculture and its concern for society and environment, plays a vital role in economic viability and ecological sustainability of agriculture.

There are several conventional methodologies to estimate the level of profit and efficiency of production system at enterprise level. Only marketable factors are considered in conventional methods keeping the non-marketable component of production system away. Non-marketable component of a production system includes various social and environmental dimensions of it. Nammalwar (1997) has explained the concept of environmentally sound and sustainable enterprises, which include the physical resources, ecological resources, human use value, quality of life values with either way impact of agriculture and environment. In recent years, non-marketable dimensions of agricultural activities have been given importance because of its concern for the environment and society. This chapter provides a methodology that incorporates non-marketable component of agricultural enterprise besides its marketable component. The Resource Cost Ratio (RCR) approach is a modified methodology developed by Debnath et al. (2010) from Domestic Resource Cost Ratio (DRCR) that Morris (1990) has applied at macro-economic level to determine the comparative advantage between countries.

Agronomical practices is the collection of operations starts from field formation, tillage, sowing, irrigation, manure and fertilizer management, pest control and harvest etc. Though, the type of agronomical practices varies with the crop, the basic function of various agronomical operations remains the same for all the crops. Considering that, understanding the basics of general agronomical practices is crucial for good agricultural practices and optimum production.

Tillage

Tillage is the basic activity of preparing the land for the crop production.

ountains occupy twenty-four per cent of the global land surface area (about 25 million km²) and are home to twelve per cent of the world’s population (GTOS, 2008). Water is present in snow, glaciers, wetlands, and rivers in the mountains. They supply watersheds by providing groundwater recharge to hill communities and communities living in vast basin areas (Hua, 2009). Whatever happens in these mountains affect nearly 1.2 billion people, one-fifth of the world’s population living in the river basins, and up to three billion indirectly in food and energy production. Despite harbouring some of nature’s richest natural resources, mountains are home to some of the world’s poorest people, many of whom are marginalized subsistence farmers. These communities living in the mountain region have hardly benefited from the ‘green revolution’ and global economic growth.

Introduction

Agricultural extension has been developing from past more than 100 years. The term was first used by Universities of Cambridge and Oxford, in the year 1867. Chinese people have been following extension approximately from past 2000 years. There are four generations of agricultural extension in Asia: colonial, diverse top-down, unified top-down and diverse bottom-up extension. Communication takes place mainly in two ways in extension system: paternalism versus participation and persuasion versus education, which aims to change behaviour of rural people. Many approaches have emerged in extension which includes ICT based extension.

In this chapter we will discuss about economics of raising 100 Khaki Campbell duck for egg production. Popular breed of ducks for egg production includes Khaki Campbell and Indian Runner. Among the egg laying breeds, Khaki Campbell is the best producer. Individual egg production of almost an egg a day in this breed for well over twelve months has been recorded and flock averages in excess of 300 eggs per duck per year are not uncommon. Khaki Campbell ducks weigh about 2-2.2 kgs and drakes 2.2-2.4 kgs. Egg size varies from 65-70 gms.

Cost and estimates for establishment of a 100+15 Khaki Campbell duck unit (under semi-intensive system)

Education: Education is the production of desirable changes in the behaviour of the people. It is the production of desirable changes in human behaviour in knowledge (things known), attitudes (things felt) and skills (things done), in all of them or in one or more of them.

Behaviour: Includes three components viz., knowledge, attitude and skill

Knowledge (Cognitive): It includes facts, concepts, principles and relationship.

Attitude (Affective): An attitude can be loosely defined as a feeling towards some object, person and situation or idea.

Introduction

In the midst of the rapid speed of global change and in a highly competitive and risky business situation, the knowledgeable consumer gains power, and the market shift towards quick product creation. Innovation has emerged as a crucial component of success, particularly for new businesses, involving the development of economic productivity and operational and working producers (Baron and Tang, 2011). The systematic and planned transformation of a person into an entrepreneur is known as entrepreneurial development. The process of making an entrepreneur involves teaching everyday people how to be business owners, as well as imparting the necessary information, management, technical, financial, and marketing abilities. The definition of the entrepreneurial developmentprograme is a course created to assist a person in enhancing their entrepreneurial drive and obtaining the knowledge and talents required to carry out their position as an entrepreneur successfully (Kumari, 2014).

• Used for various digestive problems including heartburn, intestinal gas, bloating, loss of appetite and colic in infants.

• Source of copper, potassium, calcium, zinc, manganese, vitamin C, iron, selenium and magnesium.

• The seeds are used as condiment

• Seeds yield 4-5% volatile with anethole as major constituent.

Demand for fodder in intensive livestock farming necessitates the fodder seed production in all the livestock and fodder farms for their own use and sale to needy. In the recent past, fodder seed production is also becoming commercial activity of farmers as the income is promising. Since, there are number of new varieties of fodder are coming to the market, demand for their seed is also encouraging to produce the same commercially. Considering this, the farm managers should aware of fodder seed production technologies for cost effective and quality fodder seed production.

1. Introduction

Extrusion of foods is an emerging technology for the food industries to process and market a large number of products of varying size, shape, texture and taste. Extrusion cooking of cereals is becoming more adaptive due to its various advantages over the traditional food processing techniques (White, 1994). Nowadays the extrusion of food is of major importance in the food-processing sector and it is the only process, which covers a wide range of food products such as ready to eat (RTE) breakfast cereals, snack foods, baby foods etc. Elaborate scientific research, technological development and engineering design, which have been done in this field so far, have led to large-scale industrial production. 

Introduction

In agriculture, Knowledge and decision-making capacity determine how production factors like soil water and capital are utilized in judicious manner. Agricultural Extension System remains in central position for formulating and disseminating knowledge including hands on training to the farmers. Realizing the scope and importance of integrated working of inter relationship between research, education and extension functions, the ICAR established a section of extension education at its head quarter in 1971 which was later on strengthen and renamed as Division of Agricultural Extension. Extension Education plays an important role in most of the Agricultural Development project. Moreover, Agricultural Extension is part of system of factors which influence farmer’s decision. It includes agricultural researchers, political authorities, farmer’s organization, non-govt. organizations, farmers training centre and media. These actors assume the functions of research, information dissemination, training and so on. The primary goal of agricultural extension is to assist farming families in adopting their production and marketing strategies to rapidly changing social, political and economic condition so that they can, in the long term, shape their lives according to their personal preferences and those of community.

Our country today is considered independent. We have the freedom to live by our choices, and there is no discrimination between women and men. Nowadays, women and men get equal opportunities to earn their livelihoods. Women’s work is restricted to the households and jobs outside the home to contribute to the family’s economy. As industrialization occurs, the demand for labour and employees is also increasing. This has created opportunities for both women and men to work equally.

Extended Summary

Kiwifruit is recent crop introduction tohorticulture practices in Mid-Himalayan statesin India such as, Himachal Pradesh and J&K in the North-West and Sikkim, Arunachal Pradesh and Nagaland in the North-Eastern Himalayas.Over past few years this fruit has attainedimmense popularity and among consumers due to its nutritional value, while also it has gained appeal among small and marginal farmers owing to its high benefit-cost ratio,particularly through Hi-Tech cultivation techniques.

Kiwifruit,also known as Chinese gooseberry (Actinidia chinensis Patch) is believed to have originated in China,although it gained popularity in New Zealand. In India, Kiwi was first introduced in Lal Bagh at Bengaluru,however,it was soon observed that the fruit could be cultivated well only inthe semi-temperate climate of Himachal Pradesh, around1963.

Executive summary

The ITK system had been developed by the indigenous communities based on their experiences, continuous improvement through informal experimentation and transfer of such knowledge to next generations. The tried and tested rich ITK pertaining to agriculture, livestock and other allied sectors had been interwoven with the socio-cultural and traditional practices followed by them. Since time immemorial indigenous communities had been applying ITK in animal husbandry to increase milk production, fertility, retention of placenta, breeding, prolapsed, care for the young stock and preparation of indigenous livestock products. ITKs are often adapted according to the local culture and traditions, needs, and environment; they are very dynamic and continuously changing, and lay emphasis on minimizing the risks rather than maximizing profits. Indigenous knowledge of livestock rearing is often “tacit” and not necessarily expressed in the conventional form of scientific documentation. The origin and evolution of indigenous technical knowledge (ITK) in India has been reported since time immemorial. Since then, the knowledge, belief, skills and practices pertaining to diagnosis, treatment and management of animal and human diseases are imprinted and carried to future generations. In the light of evolution, the practice has come to limelight as an alternative low cost solution to conventional western medicine and readily practiced by ordinary farmers. 

Pure-breeding

Mating purebred individuals of the same breed. The progeny share the same genetic make-up. The primary goal of pure-breeding is to identify and propagate superior genes for use in commercial production, primarily through crossbreeding programmes, as well as to identify and propagate better females for the preservation of precious genetic material. Therefore, crossbreeding will be futile unless superior purebred individuals are used.

Poultry in general and duck in particular are not free from diseases though they are far more cold-hardy and healthier than the chickens. Infectious agents are not the only cause of diseases in poultry. However, it can be affected by a wide range of diseases that is caused by the non-infectious agents and it can range from cases of cannibalism to various nutritional related diseases or disorders. Unlike the infectious diseases which tends to affect a whole litter, non-infectious diseases may however be sometime confined to a single bird.

Non infectious diseases can be basically categorized into subgroups like –

Introduction

Agricultural and Animal husbandry extension continues to be in transition worldwide. Governments and international agencies are advancing structural, financial and managerial reforms to improve extension. Decentralization, pluralism, cost sharing, cost recovery, participation of stakeholders in development initiatives and the decisions and resources that affect them - these are some of the elements in extension’s current transition.

Public sector extension was severely attacked in the 1980s for not being relevant, for insufficient impact, for not being adequately effective, for not being efficient and, sometimes, for not pursuing programmes that foster equity. In the context of meeting the holistic needs of increasing agricultural production in a sustainable manner in India, agricultural extension has a crucial role to play. Reforms in the system envisaged an extension service which is more broad-based and holistic in content and scope and beyond agricultural technology transfer.

Women have been seen as necessary as a man. The status of the women and the work progress of the women have been seen as a nation’s overall progress. Without the penetration of women in socio-economic and political activities, the country is considered to stagnate. Still, the devaluation of women commences at birth with the preference for male offspring. This continues through childhood conditioning to the submissive and, later on, the subservient role required of them in the marital home.

Pedigree method of plant breeding is defined as a method of breeding in which individual plants are selected in the segregating generations from a cross on the basis of their desirability judged individually and on the basis of a pedigree record. This has been the most widely used method of plant breeding in all the self-pollinated crops and still continues to be so. This method has been first described by H. H. Lowe in 1927. This is the most widely used method to handle segregating generations following crosses between two parents to develop new cultivars combining desirable traits from both the parents. In this method, superior types are selected in successive segregating generations and a record is maintained of all parent-progeny relationships. The records help the breeder to advance only progeny lines with plants that exhibit genes for the desired traits. Selection begins in F2 generation where individual plants are selected which in judgment of breeder will produce the best progeny in F5/F6 when the selection is finally concluded. In F3 and F4 generations, many loci will have become homozygous and family characteristics begin to appear. By F5/F6 generation, most families are expected to be homozygous and uniform and hence selection within such families is no longer effective. 

Introduction

Quality of Work Life (QWL) is a popular concept among the organizations. Work is an essential part of everyday human life. Work influences the overall quality of life. Human resources are one of the main assets of any organization. Quality of work life (QWL) is one of the important subsystems of human resource management. There are economic, social, psychological and organizational aspects of work life. Many new subsystems are being added to human resource management with employees’ changing needs, culture, expectations, and work environment.

Seed quality is the possession of seed that is genetically pure and physically homogeneous, coupled with health and wellness.

A seed is the first genetic material that becomes the basis for future agriculture and seeds are the basic building blocks of agriculture. A great deal of farming has been modernized by technology, but without a regular and steady supply of high quality seed, yields would be drastically reduced and crop quality would decrease as well. The production of horticultural and agronomic crops depends largely on quality seed. For farmers, seed characteristics such as genetic purity, germination percentage, vigor, and appearance have a significant effect on yield. Every professional seed producer strives to achieve and maintain high seed quality.

Single seed descent (SSD) method of breeding is applicable to self-pollinated crops. The method of single seed descent (SSD) was born out of a need to speed up the breeding programme by rapidly inbreeding a population prior to initiating individual plant selection and evaluation while reducing a loss of genotypes during the segregating generations. SSD procedure is based on advancing generations through single seed from each plant in each generation. This separates the inbreeding phase from the selection phase and the population reaches F6 generation faster. This procedure carries forward maximum number of F2 plants to a stage near homozygosity, i.e. F6. It was first proposed by C. H. Goulden in 1941 when he obtained the F6 generation in two years by reducing the number of generations grown from a plant to one or two while conducting multiple plantings per year using greenhouse and off-season planting. H. W. Johnson and R. L. Bernard described the procedure of harvesting a single seed per plant for soybean in 1962. However, it was C.A. Brim who, in 1966, provided a formal description of the procedure of single seed descent, calling it a modified pedigree method.

Abstract

The Car Nicobar Island is one of the several islands in Indian Ocean which was severally damaged by the Great tsunami on 26 December 2004. The great tsunami event caused massive devastation, in the form of loss of life and property in south and south East Asia. The objectives of the study are to assess the changes in the coastal features of the Car Nicobar Island using various indicators such as the tsunami height, run- up elevation, water flow direction, erosion, sand deposition and coastal subsidence. Andaman &Nicobar Islands are the summit of the submarine mountain range lying along the great tectonic suture zone extending from Eastern Himalaya to Sumatra and Lesser Sunda via Myanmar border and Arakan hills. The IRS P-6 satellite data has been found to be very useful in the present tsunami assessment studies. The digital analysis of the satellite data was done using the image processing software (ERDAS IMAGINE 8.4) and DTM to quantify the tsunami height (15 m), run up elevation (2-19 m), inundation (295-1203 m) and coastal responses. The settlements and coconut plantations have been severely damaged in the island, which were assessed using GIS analysis of the pre and post-tsunami satellite data.

Keywords: Tsunami, Wave Height, Run-up Elevation, Inundation, Coastal Responses, Remote Sensing, GIS.

Aim: Perform an experiment to determine the parameters of a three-phase induction machine.

As the circuit modal of an induction motor is similar to that of a transformer, the parameter of the modal can be obtained by no-load test and blocked rotor test.

No-load test

In this test, the motor is to run at no-load at rated voltage and frequency. The applied voltage and current and power input is measured. Power input at no load (Po ) provides only the losses that are rotational losses.

Aim: Study of 3 point and 4-point starter.

Theory

A 3-point starter in simple words is a device that helps in the starting and running of a shunt field or compound excited dc motor. Now the question is why these types of dc motors requires the assistance of the starter in the f irst case. The only explanation to that is given by the presence of back emf Eb , which plays a critical role in governing the operation of the motor. The back emf, develops as the motor armature starts to rotate in presence of the magnetic field, by generating action and counters the supply voltage. This also essentially means that the back emf at the starting is zero, and develops gradually as the motor gathers speed.

The pesticides-one amongst the most important inputs in the crop production contributed a lot to minimize the losses to crop yield. In India, on an average, 33 % of crop loss occurs due to pests and disease and runs to an estimated Rs 1.40000 crore. Pesticide is an essential in the farmers struggle to protect their crops. Pesticides consumption in India reported to 288g/ha is very low compared to global average of 900g/ha. Excessive, irrational and indiscriminate use of these pesticides causes many negative consequences, mainly the famous 3 R viz; Resistance, Resurgence and Residue aspects.

Introduction

Quality seed plays seminal role in augmenting agricultural production as well as productivity. Only by using good quality seeds, productivity can be enhanced up to the tune of 15-20 per cent alone, but under optimum management, the increment may touch upon up to 45 per cent depending upon the crops since the efficiency and efficacy of all other inputs in the production technology gamut are contingent upon the quality of seeds being used. Since antiquity the importance of quality seed to enhance agricultural productivity is well evident as mentioned in old testimonials, literatures, scriptures, treatises, epics, and many other ancient documents.

Seed quality is the major decisive factor governing stand establishment of any crop and thus having immense importance and bears utmost priority in case of high value, low volume crops like vegetables in particular and for high volume low value crops in general for enhanced productivity and production as well (Mandal et al., 2015). A number of diverse materials/ treatments at varying doses have been used to increase the rate and uniformity of seedling emergence in wheat and rice, which are generally categorized for seed enhancement, which is a kind of value addition.

Seed enhancement may be defined as post-harvest treatments that improve germination and seedling growth or facilitate the delivery of seeds and other inputs/materials required at the time of sowing smoothly. Seed enhancement technology predominantly possess a central objective to further improve seed performance by treating with specific additives/ chemical/ organics/ botanicals, etc. under very specific regimes and with the aid of certain planting equipments to grow uniform crop obviously to harness higher productivity and production (Halmer, 2006). Various techniques have been employed to assure superior performance of additives in different crops and most have been found to have immense commercial application (TeKrony, 2006). This includes three general areas of enhancement: pre sowing hydration treatment (priming), coating, pelleting technologies and seed conditioning.

Abstract

This chapter presents the principle of fluidisation and its use in drying of food materials. Being a convective drying process, capacity and kinetics are limited by process conditions and material properties. The influences are discussed as well as presenting the main equations that describe drying in fluidised beds. The main focus lies on hot gas drying, additionally superheated steam drying as well as atmospheric fluidised bed freeze drying and microwave-assisted fluidised bed drying are presented and discussed.

Introduction

Seed as an input is the precursor for agricultural development as it alone can guarantee 20-30 per cent share of crop productivity (Koudinya and Kumar, 2014). Rigveda, the world’s most ancient scripture available, prescribes the importance of seeds as “Subeejam Sukshetre Jayate Sampadyate” which literally means, “A good seed in a good field can lead to the prosperity and posterity of the entire human race”. Seed production is indeed important to take care of a country’s food and nutritional security needs. At the same time, seed export across countries is vital for ensuring competitiveness in the domestic seed industry besides generating employment and valuable foreign exchange which in turn can be used for scaling up the seed sector’s efficiency itself (Poonia, 2013). As a matter of fact, seed trade is one of the reasons for huge advances made in the Indian seed industry through development and exchange of genetic transformation, marker-assisted breeding and nanotechnology (Nandi et al., 2013). As of 2014-15, global seed industry has reached USD 45 billion in which international seed export alone was worth USD 10 billion. Further, with the estimated growth rate of 9.2 per cent during 2015-2020, the world seed business is expected to be over USD 92 billion. Presently, USA, China, France, Netherlands and Brazil are the top markets comprising more than 66 per cent of the global share in seed trade. Corn, soybean and vegetables account for more than 75 per cent of the total global seed market volume. As of 2014-15, the value of the Asian vegetable seed market was USD 6.75 billion in which China had a major share (41 per cent) and the Indian share was around 7 per cent. Moreover, the world vegetable seed market alone is expected to grow at the rate of 7 -8 per cent per annum and reach USD 8.8 billion by the year 2020 (Parashar and Kumar, 2016).

Introduction

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

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

Organic agriculture or farming is very much native to India. Whosoever tries to write a history of organic farming will have to refer India and China. The farmers of these two countries are farmers of 40 centuries and it is organic farming that sustained them. This concept of organic farming is based on following principles:

• Nature is the best role model for farming, since it does not use any inputs nor demand unreasonable quantities of water.
• The entire system is based on intimate understanding of nature’s ways. The system does not believe in mining of the soil of its nutrients and do not degrade it in any way for today’s needs.
• The soil in this system is a living entity.
• The soil’s living population of microbes and other organisms are significant contributors to its fertility on a sustained basis and must be protected and nurtured at all cost.
• The total environment of the soil, from soil structure to soil cover is more important.

Abstract

Mushrooms are the fruiting bodies of fungi, a group of organism that is different from fruits and vegetables. They are a rich source of good quality protein having more essential amino acids and vitamins with low calories. There are about six commonly known edible mushrooms throughout the world with button mushroom (Agaricus bisporous) being the most familiar and commercially important variety. Mushroom is a highly perishable product with a shelf life limiting to a few days. Soon after harvest, it starts to undergo physiological disorders like shriveling, wilting, liquefaction, browning, textural as well as weight losses and flavour changes. The main responsible factors for the quality deterioration after harvest are respiration rate, browning, bacterial spoilage of mushrooms, temperature and relative humidity. Because of its limited shelf life under ambient conditions of temperature and humidity, the preservation of mushrooms is a matter of concern. Various techniques have been involved in the extension of shelf life of mushrooms including chemical treatments, cooling, modified and controlled atmospheric storage, radiation, drying etc. Drying is one of the most accepted and effective methods for the long term storage of mushrooms. Mushrooms preserved by drying have a pleasant flavour and are used as an important ingredient in several food formulations including salads, instant soups, meats and rice dishes. Various drying processes like sun drying, hot air drying, freeze drying, vacuum drying etc. can be used for the long term storage of mushrooms. As mushrooms are sensitive to temperature, determining the right drying method is the key for the successful and effective operation of the system. The different operating conditions involved in various methods of drying affect product quality considerably. The effect of drying methods on the process and the quality of the dried mushroom is explained in detail in this chapter.

India is blessed with wide range of diverse agro climatic conditions, making it an appropriate place for vegetable cultivation, resulting in increasing vegetable production from has increased from 63.8 MT in 1993 to 168.5 million tonnes in 2015-16 and productivity from 12.6 MT/ha to 17.8 MT/ha (www.indiastat.com). Although the production has increased but still the technology used and practices followed is predominantly traditional resulting in low productivity and inconsistent quality and quantity of produce supplies to various markets in the country. The per capita consumption of vegetables in India is very low against WHO standards and FAO recommendation (135 g/day <180 g/day (WHO standards) < 300 g/ day capita (FAO recommendation).
