Training Need Assessment

Training Need Assessment (TNA) is the method of determining if a training need exists and, if it does, what training is required to fill the gap. TNA seeks to identify accurately the levels of the present situation in the target surveys, interview, observation, secondary data and workshop.

An assessment process that serves as a diagnostic tool for determining what training needs to take place. 

Introduction

Apomixis is a phenomenon in which there is development of seed without fertilization or sexual fusion. Embryo develops without fertilization in apomixis. Hence, apomixis is an asexual means of reproduction therefore the genotype of plant will be same as of mother plant. Apomixis was first time discovered by Leuwenhock in 1719 in citrus whereas the term apomixis was first time used by Winker in 1908.The main benefit of apomixis over sexual reproduction is the selection of individual plant with superior characters and propagation of clonally through seeds. Higher plants commonly exhibit apomixis. There are more than 300 species belonging to 35 families that exhibit apomixis. Most commonly, it occurs in Gramineae, Compositae, Rosaceae, and Rutaceae.

A nursery is a place, where seedling, saplings, trees, shrubs and other plant materials are raised and sold out for planting in gardens and orchards. The prerequisites of a successful and remunerative fruit production are the availability of true-type, healthy and good quality planting materials. Nursery is, therefore, a place where one can produce true to type plants by gaining technical skill, maintaining plants property and by careful planning. Like orchard establishment, establishment of a nursery is also at permanent venture and any mistake made initially can’t be rectified easily in the later stages. Therefore, for establishing a nursery, due care in selection of site, plants to be raised and transportation facilitation etc. must be given.

Nurserymen and propagators propagate different types of horticulture plants with seeds, cuttings, and other methods. Regardless of the medium used, an ideal medium should have the following characteristics:

1. The medium should be sufficient firm and dense to told seed or cutting or layer firmly in place during germination or rooting.
2. The volume of the medium should remain constant upon drying or wetting.
3. This medium should be able to hold and deliver an adequate amount of moisture to the seeds, cuttings or layers.

1. Determination of qualitative nursery planting materials

1.1 Quality assessment of seedlings

Nursery is a place where young/infant seedlings are kept under intensive care until they are ready for planting. The production of quality seedlings begins with the collection of quality seed, nursery establishment, and after-germination maintenance. The quality of plant propagation structures may not be a qualitatively gradable criterion, but it can be indirectly assessed by their relationship to growth, productivity, and vigour. The Dickson Quality Index (DQI) is very useful for assessing the quality of a specific group of seedlings. This is done by selecting some seedlings at random from that group and computing Dickson Quality Index (DQI).

Agriculture is under increasing pressure to produce more food, feed, and biofuel from limited land resources. The current over-reliance on a few key staple crops causes a variety of agronomic, ecological, nutritional, and economic issues and is likely unsustainable in the long run.

Vegetables have a high commercial value in general and hence contribute significantly to household income. Significant research, breeding, and development initiatives are necessary for a number of promising crops to transform existing local landraces into competitive cultivars with broad adaptability and high commercial prospects. India has a good genetic wealth of domesticated crops, and 600 plant species represent the diversity in vegetable crops out of 20,000 angiosperm plants; however, only one-fourth of these are used as major vegetable crops, with the rest classified as minor, underutilized/neglected, rare vegetables, lesser-known vegetables, wild edible vegetables, and so on. Access to the genetic diversity of these selected crops is required for success

Asparagus is an herbaceous perennial that is widely grown in the United States, Germany, Spain, and France, with India contributing only a little amount. For many years, asparagus has been grown. This was a favourite crop of the Ancient Greeks and Romans. It belongs to the Liliaceae family and is thought to have originated in the eastern Mediterranean and further east in the Caucasus Mountains. It’s a monocotyledonous perennial that’s farmed for its edible stems (spears).

Lima beans are flat green or light green beans. It is only utilised for the seed because the pods are coarse or woody. There are two kinds used in commercial canning: a climbing or pole variant and a dwarf or bush variation. Like other legumes used for seed, the lima bean (Phaseolus Iunatus) has a wide range in seed size, shape, and colour, as well as plant structure and primary applications. For freezing, canning, or fresh market usage, mature seeds are utilised like a vegetable. Lima’s have long been used as a grain legume when they are firm and dry. Peru is where they were discovered. The first domestication occurred in the Andes around 2000 BC, resulting in a large-seeded variety (Lima type), while the second occurred around 800 A.D. in Mesoamerica, resulting in a small-seeded variation (Sieva type).

Pigeon pea seeds discovered in historical tombs suggest it was farmed in Egypt circa 2000 BC. Vavilov (1939) concluded that India is the primary origin of the cultivated pigeon pea due to the wide diversity of germplasm available. It’s a crucial location in rain-fed agriculture. It is grown on 4.92 million hectares worldwide, including 3.58 million hectares (72.7 percent) in India alone. Although the crop is planted in 22 nations, it is only cultivated in considerable areas in a handful of them. Its seeds have become a widespread food in Asia, Africa, and Latin America since its domestication in the Indian subcontinent at least 3,500 years ago. It is an important source of protein for the Indian subcontinent’s people and is consumed on a big scale in South Asia. India is a major producer of pigeon peas. Kenya, Malawi, Uganda, Mozambique, and Tanzania are major producers of pigeon pea on the African continent.

Soils vary greatly in their organic matter content. For all practical purposes the organic matter content of the soil parallels the soil N content. The C/N ratio of soil organic matter generally falls in the range of 10 to 12. Because of the ease with which Kjeldahl determination can be made, N is often used as an index of soil organic matter content.

3.1. Composition of Organic Matter in Soil

Organic matter constitutes 1 to 6% of the topsoil weight of most upland soils. In a typical grassland soil, 5 to 6% of organic matter may be present in the top 15 cm. Top soils with less than 1% organic matter are mostly limited to desert regions. On the contrary, the organic matter content of soils in low, wet areas may be as high as 90% or even more. Soils with more than 12 - 18% organic carbon (approximately 20 - 30% organic matter) are called organic soils.

Soil is the product of various soil forming factors acting on the parent material over a period of time. The parent material is usually devoid of organic matter and consists of variable quantities of sand, silt, clay and carbonates. High temperatures and adequate moisture promote mineral transformations, but these effects are magnified by living organisms and the organic substances they produce. The biosphere and the organic substances they produce are directly or indirectly responsible for the following:

1. Decay of organic matter by microbes leads to the formation of CO₂ which is quantitatively the most important “aggressive” weathering agent because of its tendency to form carbonic acid with water [CO₂ + H₂O → H₂CO₃].

The synthesis of humic substances is the least understood and the most intriguing aspect of humus chemistry. This has been one of the intensely- researched subjects for a long time. Formation of humic substances takes several pathways during the decay of plant and animal remains in soil and the four important ones are shown in Fig. 8.1.

Fig. 8.1: Mechanisms for the formation of soil humic substances

The classical theory by Waksman advocated humic substances as modified lignins (Pathway 1), but a vast majority of current crop of investigators favour a mechanism involving quinones (Pathways 2 and 3). Including sugar-amine condensation pathway (Pathway 4), all the four pathways must be considered as likely mechanisms for the synthesis of humic and fulvic acids in nature. It is absolutely possible that these four pathways may operate in all soils, though not to the same extent or in the same order of importance. 

Introduction

The soil protozoa are unicellular and the simplest forms of animal life. Most of the protozoa are devoid of chlorophyll but transitional genera resemble the algae and possess chloroplasts containing chlorophyll pigments. The active life stage is commonly known as trophozoite phase where they feed and multiply but under adverse climatic conditions, they form resting stage or cyst, which develop a thick coating on the cell surface. Mostly, the protozoa multiply by longitudinal or transverse fission but some species reproduce sexually by fusion of two cells followed by exchange of genetic material between their nuclei and cell division.

Uncertainty is an inevitable character of any system where most of the contradictory factors are either unpredictable or unfathomable. The higher is the complexity, the lesser would be the resilience. Agricultural production system, as it is managed in Indian condition, is the most vulnerable one to a plethora of uncertainties. Mostly managed in an open air rainfed conditions, it has been exposed to weather and resource uncertainties, market volatility, poor access to technology and a fragile input delivery mechanism.

Objectives

1. To estimate and assess the general status of perceived uncertainty of farmers by scale and dimension

Plant propagation refers to the process of increasing number of plants of a cultivar. Plant propagation is of two types viz. sexual and asexual. Sexual propagation is done by seeds, whereas asexual plant propagation is done by vegetative means such as stem/root cuttings, slips, corm, bulbs, rhizomes, grafting, budding, layering, etc. Good quality seed or planting material of established crop varieties should be procured from authentic source to get desired result. The seed should be uniform in size, free from disease infestation, possess good vigour and having good viability. The quality of the seed is decided based on germination percentage. Seeds can be directly sown to raise a crop or seedlings are raised in nursery beds, which are transplanted later to main plot.

Seedlings can be raised in nursery beds, poly bags or pro-trays. The nursery beds are usually kept one meter wide, convenient length and of 15 cm height. The soil of the bed is prepared by addition of well decomposed bulky organic manure, sand and garden soil in equal proportion. The beds have to be disinfected by exposing the soil to sun (solarisation) and addition of neem or karanj oil cake. After sowing the seeds in the bed, those are covered with straw, leaves or compost to protect the seeds from birds and to conserve moisture in the soil. It also helps to maintain the temperature for quick germination. The seeds are sown in lines on the bed.

Fruits and vegetables grown in kitchen garden or in the field can be preserved in various forms like juice, squash, puree, pickle, jam, jelly, murabba, paste, ketchup, sauce, etc. for year round consumption. Seasonal produce of vegetables and fruits can be preserved through various methods for consumption at a later time.

Juice

Fruits like pineapple, mango, orange, lemon, etc. can be used to prepare juice, squash and other ready to serve beverages. Beverages can be prepared by following various steps. The fruits are washed thoroughly and pat dried with clean cloths. Then the peels are removed wherever necessary. Peeling can be done by hand or by knife. The juice is extracted by using juice extractor or by netting. The extracted juice is then strained using a muslin cloth or mosquito net. To enhance the taste and shelflife, the juice is mixed with sugar syrup. The sugar syrup is prepared by dissolving sugar in water and boiling it. After the syrup is ready, it is allowed to cool and strained through muslin cloth. Then the extracted juice is added with the syrup and citric acid. Preservatives like potassium meta-bisulphite or sodium benzoate is added for storage of the juice. If necessary, essence can be added @ 2 ml/litre of juice. The juice is to be stored in a narrow mouth bottle by leaving a head space of one to two centimetres. The cap of the bottle is to be sealed with wax.

Grouping plants in different categories on the basis of similarities and dissimilarities is referred to as classification, which helps for study of these crops in various perspectives. India is endowed with a rich diversity of horticultural plant wealth due to varied agro-climatic conditions. Number of fruits, vegetables, ornamental crops, spices, condiments, plantation crops, etc. is under commercial cultivation in different parts of the country under different sets of growing conditions.

The systematic study of all these crops becomes a difficult and more repetitive part. To avoid it; classification of horticultural crops on different aspects has been made to deal with all these plants separately. Classification of horticultural crops has been made in different groups on similarity or dissimilarity of attributes. Plants having similarity in either of the traits are placed under one group. The overall objective of the classification is to categorize the horticultural plants and make the recollections very easy and convenient.

India is regarded as a horticulture paradise due to growing of tropical, subtropical and temperate fruit crops in varied soil and climatic conditions. However, increasing pressure on land owing to diversion of orchard lands to various other obvious reasons as well as rising energy and land-costs, together with mounting demand for fruits have made HDP imperative to achieve higher productivity from limited space.

There is a shift in farmers’ perception from production to productivity and profitability, which can be achieved through high density planting. India is the second largest producer of fruits in the world. However, the average productivity of various fruit crops in the country is quite less. Low productivity can be attributed to many reasons such as old and senile orchards, lack of canopy management practices, planting of poor yielding varieties, low or no adoption of recommended package of practices by the farmer leading to poor orchard management, etc.

In India, some of the major horticultural crops productivity is affected by major problems. Some of these have been overcomed by certain control measures strategies. However, a few of them are long lasting and have attained the status of national problems. These are mango malformation, alternate/biennial bearing, spongy tissue in mango, bunchy top of banana, guava wilt, citrus decline, rootwilt of coconut and yellow leaf disease of arecanut.

Mango malformation: Mango malformation was reported for the first time from Darbhanga, Bihar. The disease is more prevalent in northwest than northeast and south India. This disorder is widespread in flowers and vegetative shoots.Three types of symptoms are mainly observed. These are bunchy top phase, floral malformation and vegetative malformation. Bunchy top phase is observed in nursery, bunching of thickened small shoots, bearing small rudimental leaves. Shoots remain short and stunted giving a bunchy top appearance. In vegetative malformation, excessive vegetative branches of limited growth are observed in seedlings. 

Adverse climatic conditions like temperature, humidity, frost etc. affect vegetative growth, flowering, fruiting as well as quality of horticultural crops. Tropical crops are usually more sensitive to low temperature and frost injuries whereas temperate crops are vulnerable to high temperature effects. High temperature beyond tolerable limits may cause sunscald, tip dieback, bud death and heartwood damage. On the other hand, when temperature drops below the freezing point; water molecules ice formation in the intercellular spaces takes place showing freezing injuries on various plant parts. The symptoms like dehydration and necrosis are visible on plant due to increased concentration of sugars within the cell causing reduction in the water content. The extent of damage will depend upon the prevailing low temperature and its duration. Exposure of the plant near freezing temperature for prolonged time causes death of the plant due to formation of ice crystals in intercellular spaces.

Precision farming is an approach, where inputs are utilized precisely to get increased average yields as compared to traditional cultivation techniques. Precision farming aims to improve crop performance as well as environmental safety. In other words, precision farming is the matching of resource application and agronomic practices with soil attributes and crop requirements as they vary across the field. Precision farming can improve both yield and profits by using optimum resources, while at the same time making agriculture more sustainable and less polluting. Sustainable precision farming is the most valuable innovation in farm management that is based on using Information and Communication Technologies (ICTs). This is the most recent innovation technology based on sustainable agriculture and healthy food production. Popular definition of Precision Agriculture (PA), Satellite Farming or Site Specific Crop Management (SSCM) describe the term as ‘a technology enabled approach to farming management that observes, measures, and analyzes the needs of individual fields and crops’.

The term biodiversity is abbreviated from two different terms ‘biological’ and ‘diversity’. Biodiversity is also called biological diversity. The term biological diversity was first coined by wildlife scientist and conservationist Raymond F. Dasmann in 1968. The same term i.e. natural heritage was used in the United State. Geneticists describe it as the diversity of genes and organisms. Biologists define biodiversity as the sum of genes, species and ecosystems of a region.

Biodiversity is determined by the wholesome number of different species in a particular area. It helps to strengthen the stability of an ecosystem and leads to a healthy biosphere. Existence of biodiversity is crucial for the functioning of the ecosystem and is the foundation of life on earth as it generates products and services for the existence of all living organisms on the earth.

Many horticulture schemes have been launched by the Government. The main aim is to expand the area under horticulture with better productivity. These ambitious schemes are as follows.

A. Mission for Integrated Development of Horticulture (MIDH): Mission for Integrated Development of Horticulture (MIDH) is a centrally sponsored scheme from 1st April 2014 for the holistic growth of the horticulture sector covering fruits, vegetables, root and tuber crops, mushrooms, spices, flowers, aromatic plants, coconut, cashew, cocoa and bamboo. Under MIDH, Government of India (GOI) contributes 60% of total outlay for developmental programmes in all the states except states in North East and Himalayas, 40% share is contributed by state governments.

Indian Council of Agricultural Research; formerly known as Imperial Council of Agricultural Research, established on 16^th July 1929 and located at New Delhi. It is an autonomous organization under Department of Agricultural Research and Education (DARE), Ministry of Agriculture and Farmers Welfare, Government of India. It is the apex body for coordinating, guiding and managing research and education in agriculture including horticulture, fisheries and animal sciences. This is one of the largest national agricultural systems in the world.

The ICAR has played a pioneering role in ushering in the green revolution and subsequent developments in agriculture through its research and technology development. Thus, the food grains production increased by 5.6 times, horticultural crops by 10.5 times, fish by 16.8 times, milk by 10.4 times and eggs by 52.9 times to achievenational food and nutritional security during the period of 66 years (1950-51 to 2017-18). It has also played a major role in promoting excellence in higher education in agriculture. Organizational setup of ICAR to achieve mandate is as follows.

1. Introduction

The status of mechanization in India is at a very low level for horticultural crops. The farmers usually go behind the use of traditional methods for different farm operations (Fig 1) and practices for cultivation of horticultural crops, their handling, storage, and processing. This results in less yields, high cost of cultivation and high crop losses from harvesting till processing. The use of different available hand tools, machinery and hi-tech technologies in the production and processing of the crops will lead to increased yields and decrease in losses to a great extent (Mandhar, 1999).

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

Plant diseases create challenging problems in commercialagriculture and pose real economic threats to bothconventional and organic farming systems. Plantpathogens are difficult to manage for several reasons.First of all, plant pathogens are hard to identify becausethey are so small. The positive identification of apathogen often requires specialized equipment andtraining, and in some cases accurate diagnosis in thefield is difficult.Plant pathogens are constantly changing and mutating,resulting in new strains and new challenges togrowers. Disease management is complicated by the presenceof multiple types of pathogens. For any crop thegrower must deal with a variety of fungi, bacteria, viruses,and nematodes. This situation is even more complicatedfor organic crop production because they usuallyproduce a wide array of crops and are prohibitedfrom applying conventional synthetic fungicides.The world market continues to be extremely competitiveand continues to require that growers supplyhigh-quality, disease-free produce with an acceptableshelf life.

Introduction

Floriculture or flower farming is the study of growing and marketing flowers and foliage plants. Floriculture includes cultivation of flowering and ornamental plants for direct sale or for use as raw materials in cosmetic and perfume industry and in the pharmaceutical sector. It also includes production of planting materials through seeds, cuttings, budding and grafting. In simpler terms floriculture can be defined as the art and knowledge of growing flowers to perfection. The persons associated with this field are called floriculturists.

Worldwide more than 140 countries are involved in commercial Floriculture. The leading flower producing country in the world is Netherlands and Germany is the biggest importer of flowers. Countries involved in the import of flowers are Netherlands, Germany, France, Italy and Japan while those involved in export are Colombia, Israel, Spain and Kenya. USA and Japan continue to be the highest consumers.

1. Introduction

Uttarakhand is extremely vulnerableto climate-related changes due to its varied geography and rich glacier mass. The relationship between climate change and agriculture is not a new phenomenon. In the last 50 years, there has been a lot of academic focus on dealing with climate change issues in agriculture. Climate change is believed to affect agriculture by inducing changes in farmer’s behaviour, quantity, quality, cost of production, changes in production, consumption, prices & trade patterns; changes in market responses at global & local levels and these changes not only depend on the domestic and international adaptive capacity their economic impacts also vary by region, by sector, and by stakeholders’ groups. Climate change is a major global environmental problem and also an issue of great concern to all countries, irrespective of their size or level of development. It is established that adverse impacts are likely from increased frequency of extreme weather, floods & droughts, and submergence of coastal areas due to sea level rise and extreme climate variability. It is considered that mountain regions are vulnerable to climate change & it will have direct impacts on livelihoods as most of the economic & livelihood sectors are vulnerable to the effects of climate change.

Introduction

Agriculture is the foundation of India’s economy, as it provides food to people, feed to cattle, raw materials to primary and secondary industries, contributes upto 19 percent of GDP and employs 54.6 percent of the workforce (Kirti and Prasad, 2016). Due to diverse soil and climate conditions, vast varieties of crops such as cereals, pulses, spices , millets, oilseeds, flowers and fruits are being grown in India. Among these crops grown, India is among the leading producers of pulses, cereals and spices in the world (Mishra et al., 2021). India is the fourth largest oilseed economy in the world. Among oilseeds, there are nine crops that are the primary sources of oils in the country, out of which seven are edible oils (soybean, rapeseed-mustard , groundnut, sunflower, sesame, niger and safflower) and two are non-edible (linseed and castor).

Introduction

India is an agricultural economy and the agriculture sector contributes 18.40 per cent to the Indian Gross Domestic Product (National Accounts Statistics, 2020-21). It is considered to be a major sector for its contribution to the Indian GDP. Agriculture is the source of income for 65 per cent population of the country. This sector is becoming innately insecure due to several reasons such as production, lack of financial resources, climate conditions and personal attitude of the young generation towards agriculture. It is right to say that agriculture is the “Gamble of Monsoon’’ because lack of precipitation can lead to drought and excessive precipitation can leads to floods.

The Preamble of the Indian Constitution promises to all citizens of India social and economic justice apart from political justice and also equality of status and opportunity¹. Although every citizen in India who is more than eighteen years of age, including farmers and agricultural workers have got political justice in as much as they have a right to vote and also contest in elections to the State Legislative Assembly and to the Houses of Parliament, we have not been able to give them social and economic justice, and equality of status and opportunity mainly because they continue to earn income, which are not enough to take care of the essential needs of the family such as food, clothing, shelter, education, health, recreation etc. When the Constituent Assembly adopted the Constitution of India on November 26th 1949, agricultural land was owned by Zamindars and big landlords, and most of the agriculturists were working on their land either as tenants or as agricultural workers. Consequently, most of the citizens of rural India did not own agricultural land and had very little earnings either as tenants or as agricultural workers.

Introduction

Main stay of Indian floriculture is to grow traditional loose flowers mostly for worship, personal adornment and traditional decorations. With the evolving culture of ‘saying it with flowers’ the cut flowers sector made significant inroads in recent times. Today the traditional flowers are grown in area of 2.48 lakh hectare producing 16.58 lakh tonnes of loose flower and 4.84 lakh cut flowers (NHB 2015). India also has significant proportion of trade in potted flowering plants, ornamentals foliage plants for landscaping, turf grasses, cut foliage, dry flowers, specialty flowers, annual flower seeds and fillers. India exported floricultural produce worth Rs. 450 core (APEDA 2016) that comprises fresh cut flowers (to Europe, Japan, Australia, and Middle East, USA), loose flowers (for expatriate Indians in the Gulf and Europe), cut foliage (to Europe), dry flowers (to USA, Europe, Japan, Russia, and Australia) and potted plants (Middle East) besides seeds and planting material. The major market for domestic flowers is in Delhi, Mumbai, Calcutta, Chennai, Pune, Bangalore, Hyderabad etc. With limited infrastructure the amount of trade that takes place in the major markets varies from season to season.

Organic farming is getting more and more popular as a farm practice. Although most agricultural land is still processed through conventional farming, the demand for organic agriculture and organic crops is constantly increasing. Organic farming is defined in a variety of ways. The majority of them argue that synthetically manufactured fertilisers and pesticides are not allowed in organic farming. This is right; yet, organic farming encompasses much more. Organic farming is founded on unique qualities as a wholly natural and sustainable farm management technique. To put it another way, organic farming is both an agricultural practise and a philosophy of cooperating with nature.

India is one of the top producers of food for the entire world. In 2019–20, the nation produced a record 308.65 million tonnes (MT) of food grains. India is the second-largest producer of fruits and vegetables, producing 99.07 million metric tonnes of fruits and 191.77 million metric tonnes of vegetables in 2019–20. Horticulture production in India reached 320.47 million tonnes. India is also the world’s top producer of coconuts, the second-biggest producer of sugar, and the world’s largest producer of milk. In FY20, it was calculated that agriculture, forestry, and fishery contributed a total of Rs. 19.48 lakh crore (USD 276.37 billion).In FY20, India’s gross value added (GVA) at current prices included 17.8% from agricultural and related industries. In India, the expansion of the agricultural industry and related industries has greatly improved.

Introduction

The word entrepreneur is derived from French word “Entreprendre” which means “To undertake”. Entrepreneur represents an individual or a group of individuals, who conceive, initiate and maintain for a sufficiently long period of time, a social institution which produces economic goods (Cole, 1949).

Mushrooms have always been viewed as high medicinal and nutritional food around the world as they are consumed as medicine in Asian countries; also their medical aspects are being researched upon (Halpern and Miller, 2002). The mushroom cultivation market is estimated to account for a value of USD 16.7 billion in 2020. World production increased to 43 MT in 2018-19 (Singh et al., 2020). China is the world’s leader in production, consumption and export of mushroom followed by USA, Netherlands and Poland. Mushroom market is expected to reach USD 69.3 bn by 2024 since the market is expected to record a healthy growth of 8.2 per cent (Harsh and Joshi, 2008).

7.1. Status Vegetables are generally sensitive to environmental extremes, and thus high temperatures and limited soil moisture are the major causes of low yields as they greatly affect several physiological and biochemical processes like reduced photo-synthetic activity, altered metabolism and enzymatic activity, thermal injury to the tissues, reduced pollination and fruit set etc., which will be further magnified by climate change. The consequences of the climate change badly hit the vegetable production. Under changing climatic situations crop failures, shortage of yields, reduction in quality and increasing pest and disease problems are common and they render the vegetable cultivation unprofitable. This ultimately questions the availability of nutrient source in human diet.

Mange or parasitic dermatitis is caused by the infestation of mange mites e.g. Sarcoptes, Psoroptes, Demodex spp. and a range of other mites. The condition is characterized by itching and rubbing of the infested parts of the body against hard objects. Lesions include hair loss, dry, rough, thickened and wrinkled skin accompanied by the presence of scab and foul odour in some cases. Some mites burrow into the host epidermis (Sarcoptes) while others spend their entire life cycle on the skin surface (Psoroptes). Most mites are microscopic or less than 1mm in length; therefore skin scrapings are taken from the affected area of animals suspected to be suffering from mange or parasitic dermatitis

HELMINTHS Collection of parasites Fresh helminth parasites should be collected, as far as possible to achieve better results in staining. This can best be done by conducting a post-mortem examination of the animal for which the procedure given below should be followed. On opening the body and before removal of the viscera, examine the body cavity (for free lying parasites, e.g. Setaria), subcutaneous tissue (for Parafilaria and Hypoderma larvae) and the surfaces of internal organs for spot or nodules that might contain parasites. Remove them for histopathological examination (in 10 % formalin). Remove the visceral organs separately and place them in different enamel trays.

Diagnosis of parasitic infections is routinely done with conventional parasitological techniques as described earlier. However, when the parasitaemia is too low to be detected by the conventional methods as in subclinical infections and/or carrier animals advanced diagnostic tools are used for the early, sensitive as well as specific diagnosis. Serological techniques Diagnostic techniques used mostly in laboratories needs various reagents and equipments to perform the test. However, a diagnostic kit is the extrapolation of the same method by packing it in a user friendly format, accompanied by all or most of the reagents required to perform the test and can also be done outside the lab or under field conditions. Various immunodiagnostic kits are available which are based on different diagnostic methods like Enzyme-linked immuno sorbent assay (ELISA). Complement fixation test (CFT), Agar gel immunodiffusion test (AGID), Immunofluorescent tests (IFT), Latex agglutination tests (LAT) etc. ELISA is the most commonly used test system and numerous kits based on ELISA are available commercially.

A. Evaluation of the efficacy and resistance of anthelmintics against Helminths Anthelmintic resistance According to WAAVP (World Association for the Advancement of Veterinary Parasitology) anthelmintic resistance is a failure to reduce feacal nematode egg count by at least 95%. Technically accurate definition is that resistance is a genetically determine decline in the efficacy of an anthelmintic against a population of parasite that is susceptible to the drug. The history of parasite resistance to anthelmintic starts with the first report on phenothiazine resistance in 1957. Haemonchus contortus was the first nematode to develop resistance against different anthelmintic. The World Association for the Advancement of Veterinary Parasitology has recommended two tests for detecting anthelmintic resistance in ruminants, horses and pigs. These are in vivo test (FECRT) and an in vitro test (the egg hatch test). Detection Technique

• Sexual activity or mating behaviour is innate character of the males. Unlike the female animal, male animal has a nature of sexual receptivity permanently. • Male gonadal steroid androgen controls sexual behaviour. At regular interval of 2-4 hrs, there is secretion of testosterone which converts into estradiol due to aromatization. Due to this very frequent rise in estradiol level, male shows sexual behaviour permanently. In female animals, a rise in estradiol occurs only during estrous. • When in a group of animals, any female can be mated with any male, it is called promiscuous sexual behaviour. Sexual behaviour in some animals is according to their social structure and territorial/home range i.e. male and female share some of their home range for the purpose of mating e.g. Roe deer, Muntjak antelope etc. In some animals, both males and females share whole of their territory for the mating purpose called a harem e.g. wild rabbit. Some animals come into a temporary territory meant only for mating in breeding season e.g. seal.
