1. Introduction

India’s population is likely to reach 1.7 billion by 2050, making it as the thickly populated nation in the world. To feed the ever rising population, food production need augment by 70%. This augment is very serious since Indian agriculture is facing numerous challenges due to disintegration of holdings, ill brunt of climate change, sustaining investment, soaring fluctuation in prices and production, unorganized markets, inconsistent market performance, renovation of agricultural land intended for non-farm purposes and enlarged cost of production (Gangaiah, 2018). The current conditions of the Indian agriculture sector reflect that the farmers are facing severe deficit of income which is to an imperative issue and as a result dissuading the rural youth to take up agriculture as livelihood operation.

Introduction

Agriculture is the main occupation in India which engages nearly 119 million of farmers and 144 million landless labourers (Census 2011). According to the Agriculture Census (2012), about 80 per cent of Indian farmers fall under the small and marginal category. The average size of land holding in India is 1.15 ha which will tend to decrease in coming years due to land fragmentation, industrialization and urbanization which are forcing farmers to quit farming and look for more viable livelihood options (Bhattacharyya et al. 2018). Specially small and marginal farmers are exposed to high risk of farming due to climate vagaries, uncertainties in production and market demand, lack of access to support services and markets, limited scope of farm mechanization and the consistent failure of half-hearted government efforts which have been unable to make farming an exciting profession to the old as well as new generations. In Indian context, agriculture has never been a profession for the literate section of the society due to lower production and profitability. NSSO report (2012-13), in alignment with the current scenario, says 40 per cent farmers want to quit agriculture if they get alternatives.

Owing to several biotic and abiotic stresses, the problem of agrarian distress in India has accentuated in recent years. Government of India has taken initiative in its annual budget of 2016-17 and initiate a number of steps to alleviate agrarian distress and improve the situation before the fight for food security faces disastrous challenge from mass migration of Indian farmers to other occupations. The steps taken by the Government of India are improving irrigation efficiency, providing crop insurance, improving market infrastructure and its efficiency, promoting organic farming, restoring soil health and so on.

Introduction

The Eastern India Region comprising of Eastern UP (8.67 Mha), Bihar (9.41 Mha), Jharkhand (7.97 Mha), West Bengal (8.87 Mha), Assam (7.84 Mha), Odisha (15.57 Mha), and Chhattisgarh (13.51 Mha) occupies about 21.8% of the country’s geographical area. Endowed with plenty of natural resources, the Eastern Region of India states has not yet been able to harness its potential adequately in terms of improving agricultural productivity, poverty alleviation and livelihood improvement. Of the total geographical area of 71.84 M ha, the net cultivated area in the region is 31.21 Mha with a cropping intensity of 150%. The total food grain production from the region is 86.71 million tonnes (31.5% of the total production of India) during 2016-17. There is a large gap between potential and productivity of major field crops, livestock, fisheries, etc. in the region.

Introduction

Owing to several biotic and abiotic stresses, the problem of agrarian distress in India has accentuated in recent years. The Indian government set a target of doubling farmers’ income by 2022–2023 in its annual budget for 2016–17 and started a number of initiatives to achieve this goal, including better irrigation efficiency, crop insurance, market infrastructure improvements, organic farming promotion, soil health restoration, and others. The pathway for doubling of farmers’ income encompasses several dimensions, from production to post-harvest management. These include: bridging yield gap, crop diversification, improvements in total factor productivity and proper management of irrigation (GoI, 2007, Evenson et al. 1999) alongwith the provisions of market and institutional support for efficient post-harvest management. With respect to Himachal Pradesh, in order to improve the productivity levels of existing crop enterprises and promote the diversification of cropping systems, various steps have been taken by the line departments which include the creation of water harvesting and irrigation infra-structure, skill up gradation of farmers, subsidy on critical inputs like seed, fertilizers, plant protection materials, market access through information technology and village road network, crop insurance schemes, etc. The impact of these interventions is reflected through the continuous increase in the productivity levels and inclination of farming community towards the adoption of new crop enterprises vegetables and fruit crops.

Introduction

Dry-land horticulture has immense potential in providing nutrition rich food, social security and eco-restoration for the inhabitants of desert or rainfed and tribal land-areas of the north-western parts of India. Most of the recent past advances in Indian Horticulture are with production technology for favorable agro-climate, however, the vast and diverse land-scape of hot desert, arid, semiarid and tribal area is yet not getting logical thought for resource based horticultural development. The native crop–plants both annual and perennial are equally playing vital role for food, fodder as well income especially in the hot arid and sem-arid areas of Rajasthan where animal husbandry is also an integral component of the farming system. The monsoon supported arid zone crop-plants are drought tolerant and even the harvest failure in kharif season/ conventional cropping is very high and it is estimated 50–60% in most of the years only because of uncertainty in rain’s pattern. Based on my research experience and SWOT analysis over 25 years, it is accomplished that this hot arid zone has excellent horticultural potential with wide and varied opportunities of crop production, utilization of resources and eco-restoration (Samadia, 2016).

Introduction

Goat is being raised for centuries as poor man’s cow due to its importance of providing employment in rural areas by producing meat and healthy meat. Goats also play major role in agriculture economy of India. Goat is excellent source of additional income for poor and landless owners. Farm can start from 1 male goat and 1 female goat. The goat milk is nutritious and easily digestible milk to their kids. Goats are easy to maintain as they can graze on open land. Goat farming is an excellent option where fodder and forage is limited. Goat farmers can get good returns with successful goat rearing. Now a day, goat farming has become more commercial and many people are taking up as a challenge to meet the demand and supply. There is good encouragement from governments and providing subsidies on especially stall fed goat farming. Most of the farmers, choosing stall fed goat farming as it has its own advantages as compared to open grazing methods.

Goats are among the main meat producing animal in India, whose meat (chevon) is one of the choicest meats and has huge domestic demand. Due to its good economic prospects, goat rearing under intensive and semi-intensive system for commercial production has been gaining momentum for the doubling the income of the farmers. High demand of goat and its products with potential of good economic returns have been deriving many progressive farmers, business, professionals, ex-servicemen and educated youths to take up the goat enterprise on a commercial scale. The emerging favorable market conditions and easy accessibility to improved goat technologies are also catching the attention of entrepreneurs. A number of commercial goat farms have been established in different region of the country. Initially, farmer may face a number of problems like high cost of production, high mortality and low price of the produce, but proper training and experience may resolve this problem. In an average, mortality in the goat farm is 3-8% per annum. The contribution of goat in total livestock is 27.80% which is a major share goat in total livestock. The rank of India in Goat population is 2^nd.

Introduction

Commercial poultry farming in India has creating profitable business opportunity for entrepreneurs. Poultry farming business can provide a great employment source for the job seeking people. This is such as business in India that can never dry up. All types of poultry product have a great demand in the market inside India. There is no religious taboo about consuming the poultry meat and egg. Highly productive local and foreign breeds are available for commercial production. Requirement of initial investment for poultry farming is not too high. You can start small scale production and elaborate it gradually. Bank loans are available throughout the country. Numerous forms are available and you can easily learn about poultry farming from those established farmers. Krishi Vigyan Kendra, Samba and Animal Husbandry department of Jammu & Kashmir are providing lot of scheme and vocational training regarding poultry farming for betterment of farmers.

Introduction

Sheeps were first domesticated by human being, many thousands of years ago for their wool, meat and skins. It provides a source of income to the shepherds through sale of wool and animal. Sheep do not need expensive building to house them and require less labour than other kinds of livestock. The foundation stock is relatively cheap and the flock can be multiplied rapidly. Sheep are economical convertor of grass into meat and wool. Sheep will eat varied kinds of plants compared to other kind of livestock. This makes them excellent weed destroyer. Unlike goats sheep hardly damage any tree. The production of wool, meat and manure provides three different source of income to the shepherd. The structure of their lips helps them to clean grains lost at harvest time and thus convert waste feed into profitable products.

As the flow properties of liquids play such an essential role in our daily lives, whether intentionally or unintentionally, no one is truly an absolute beginner when it comes to rheology. Consumers not only focus on new and improved products but also consider the texture of the products e.g thick and creamy

Introduction

Dough is a complex mixture of flour constituents, water, salt and other ingredients depending upon the requirements of end-products. It is the principal intermediate stage in the transformation of wheat into different end-use products. Rheological properties of dough determine the behaviour of dough during mixing, rounding and molding used in making different products and also effect on the quality of finished product. Therefore, understanding the various features of dough rheology and their relations with product quality is important. The importance is enhanced further because of mechanization and automation of baking industry. Dough is composed of continuous phase in which gas cells are dispersed. The continuous phase is called “dough phase”. It consists of starch granules embedded in protein matrix along with some lipids, cell remnants and yeast cells in fermented dough. Gas production and retention is the most comprehensive quality requirements of the dough for bread making. The ability of the wheat dough to retain gas during fermentation and oven rise is unique. This depends on the ability of the dough to be stretched into thin membranes because of protein phase.

5.1 Downy Mildew of hemp

Pathogen: Pseudoperonospora cannabina

Geographical distribution
 
It’s spread has been limited to Asia and Europe.

Symptoms

Downy mildew begins as yellow leaf spots of irregular size and angular shape, limited by leaf veins. Opposite the spots, on the underside of leaves, the fungus emerges from stomata to sporulate. Mycelial growth on the underside of leaves is best seen in early morning when dew turns the mycelium a lustrous violet-grey colour (Fig 5.1). Lesions enlarge quickly and affected leaves become contorted. Leaves soon become necrotic and fall off. Whole plants and entire fields may follow this pattern.

7.1 Downy mildew of grape
Pathogen: Plasmopara viticola

History and Epidemics
In France downy mildew is called as “le mildiou” while in Germany it is called as “falscher Meltau”. Downy mildew is undoubtedly of American origin and was probably indigenous on the wild grapes of the eastern United States, from which it spread to the cultivated vineyards when these were established by the colonists. It was not known to occur outside America until 1870, although it was first described from this country as early as 1834. In the early part of the last century various horticultural writers referred to the destructive action of the mildew on cultivated grapes.
Its history in Europe dates back to the time when French vine-yards were suffering from the grape Phylloxera, an aphid insect pest that was also introduced into Europe from America. It was found that rootstocks of the American species were more resistant to this aphid than was the European vinifera grape, and therefore consequently around 1870 importations of the American Vines were made into Europe, and somewhere around 1875 the downy mildew fungus evidently was also introduced with these importation and became established, and by 1878 it was prevalent enough to cause alarm. Since the European vinifera grapes were far more susceptible to this disease than were the American species, it soon became a real menace to grape culture throughout the humid sections of Europe.

10.1. Downy mildew of Plantago psyllium

Downy mildew is the major and serious disease of Plantago particularly P. ovata. It causes enormous quantitative and qualitative loss and often becomes a limiting factor in the successful cultivation of the crop (Desai and Desai, 1969). Usually the disease appears at the time of spike initiation.

Pathogen: Peronospora alta and P. plantaginis

Geographical distribution
Plantago ovata under commercial cultivation has been reported to suffer from downy mildew disease. Downy mildew occurs on ripe seeds of Spanish, French and European plantago. The downy mildew is a native of Mediterranean region especially Southern Europe, North Africa and West Pakistan.
The plantago commercially cultivated in Gujarat and to a limited extent in Haryana and Rajasthan provinces in India is observed to be infected with downy mildew.

4.1. Downy mildew of sunflower

Pathogen: Plasmopara halstedii (Fort.) Berl.& de Tom.

Hosts

Over 100 host species from a wide range of genera in the family Asteraceae have been reported susceptible to this pathogen, including wild and cultivated species of Helianthus, e.g. sunflowers, which is the principal economic host. Wild Asteraceae hosts (e.g. species of the genera Helianthus, Artemisia, Xanthium, etc.) may also occur widely in the corresponding areas but their potential as reservoirs of the pest is not yet known (Virányi, 1984). For lists of hosts see Leppik (1966) and Novotel’nova (1966).

Geographical distribution

EPPO region: Present wherever sunflowers are grown, in Albania, Austria, Bulgaria, Czech Republic, Egypt, Estonia, France, Germany, Hungary, Italy, Moldova, Morocco, Poland (unconfirmed), Romania, Slovakia, Spain, Switzerland, Turkey, Russia (European, Siberia), Ukraine and Yugoslavia.
Asia: Azerbaijan, China, Georgia, India, Iran, Iraq, Israel, Japan, Kazakhstan, Pakistan, Russia (Siberia), Turkey. 
Africa: Egypt, Ethiopia, Kenya, Morocco, Zimbabwe, Uganda.

Downy mildew has been reported on a wide range of ornamentals, especially those in home gardens, but only in a few instances the diseases have been sufficiently severe and widespread .Generally the diseases have been of most concern in a few ornamentals grown as crops either out doors or under glass or in nurseries, where many seedlings are raised in close proximity, often under humid conditions which favour this disease. Downy mildew having importance on ornamentals and flowering plants are:

11.1. Downy Mildews of Anemone (Windflower)

Two downy mildews are reported on cultivated anemones. The one is caused by Plasmopara pygmaea while the other is caused by Peronospora sp.
Pathogen .1. : Plasmopara pygmaea
It was first recorded in Britain on decaen anemones near Liskeard, Cornwall, in september 1917

Symptoms
It causes blackening of the foliage of the planting. The sporangiophores emerged from stomata at the periphery of the blackened zone. The fine white mildew covers the under surface of the leaves. Plants become discolored with aborted stamens. Oospores are found in the discolored tissues.

3.1. Downy mildew of peas
It is an important disease of pea crop particularly in those areas where cool and wet climate is prevalent during its cultivation. The disease during favourable weather conditions causes considerable yield losses.
Pathogen: Peronospora viciae (formerly P. pisi)
Host range
Vigna faba, Vigna sativa. Pisum arvensis, P.sativum, Lathyrus sativus, Vicia hirsuta, Vicia sativa, Vicia villosa (Dixon, 1981).
Geographical distribution
Reports of the pathogen are from different countries on different crop host.
On Pea- Berkeley in England first discovered the disease in 1846 (Chupp and Sherf, 1960) and since then it has been found in all parts of the world where the crop is grown intensively. The occurrence of the disease has been reported from Argentina, Australia, Canada, Chile, Denmark, France, Germany, Kenya, Netherland, New Zealand, Rhodesia, Spain, Tasmania, USA, Ukrain, Italy, Poland and Australia (Dixon,1981). In India it is prevalent in Indogangetic plains including Uttar Pradesh and Punjab (Bains and Dhaliwal, 1986).

9.1. Downy mildew of Opium poppy
Pathogen: Peronospora arborescens (Berk) de Bary

Geographical distribution and losses
This is one of the serious and widespread diseases of opium poppy. The disease was observed epiphytotic in Argentina, Germany, Iran, Hungary, Austria and India. The disease was first recorded in India in 1918 and with the introduction of susceptible varieties, the disease rapidly became serious due to favourable environment in its cultivation area in India. Downy mildew now occurs in most regions in India (Rajasthan, Madhya Padesh and Uttar Pradesh). Downy mildew caused 20-30% loss of yield of opium latex. The secondary infection of downy mildew was found to reduce 11-22% latex.

Symptoms
The infection spread upwards from lower leaves. The entire leaf surface is covered by downy mildew coating, which is composed of sporangiophores and sporangia of the pathogen (Fig 9.1). The stem, branches and even capsules are attacked resulting in the premature death of the plants. The infection start from the moment the seed germinate and persist during the whole period of growth (Yossi fovitch 1929). Khristov (1943) reported that the pathogen often cause abnormal development in opium poppy. The pathogen also causes hypertrophy and curvature of stem and flower stalks.

8.1. Downy mildew of cruciferous vegetables

Cruciferous vegetables are important Kharif vegetable crops, which are grown both for table and seed purpose. This vegetable group constitutes crops like cauliflower, cabbage, radish, turnip, broccoli, brussel’s sprouts; knol-khol and rutabaga .The vegetable crops affected by downy mildews pathogen Peronospora parasitica are members of the genus Brassica and the downy mildew diseases on these crops are widespread in those regions of the world, which have cool and wet climate.

Geographical distribution

The downy mildew disease on cruciferous crops has worldwide distribution. The disease was first recorded in 1883 in USA on Brassica spp. (Farlow, 1883). In India, this disease was first reported by Butler in 1918. Subsequently various authors reported this disease from many countries of the world (Channon, 1981) particularly Angola (Serafim and Serafim, 1968), Argentine (Lindquist, 1939), Australia (Samuel, 1925; Anon., 1955), Austria (Glaeser, 1970), Bermuda (Waters-ton, 1940), Brazil (Grillo, 1937), Britain (Moore, 1959), Brunei (Herb.

Introduction

Veterinary Anatomy is regarded as the firm foundation and the knowledge gained in the subject is the basis for reasoning and helping with the diagnosis and treatment of animals. Teaching gross anatomy is highly regarded as being clinically relevant. The research on a wide range of species in Veterinary anatomy will be helping to be the understanding of their biology. The research conducted helps to understand the anatomy of domestic and wild animals and how this can be applied to diagnostic imaging and other disciplines of Veterinary Science. Hence teaching and research in anatomy provides foundation on which the knowledge of clinical practice and medicine is built. The research in Anatomy pave way for advanced research in other Veterinary Discipline.

TEACHING PERSPECTIVES

Anatomy education has entered newer and more innovative methods of teaching. “Vesalius” referred to as a founder of modern Anatomy struggled to make dissection of cadavers mandatory in 16th century and its significance is again being questioned today in search of substitutes. Hence use of alternatives to dissected specimens and multimedia teaching methodologies to teach anatomy and basic principles of Veterinary Medicine and Veterinary Surgery have gradually become more popular.

The main purpose of this lecture note is to provide basic information on patent drafting skills and train applicants for drafting a patent in clear and concise manner.

We will see the components of Complete Specification through the following Case studey (1) of a solar water heater. The figures are provided below for reference and better understanding.

Dragon fruit  (Hylocereus undatus (Haw.) Britton and Rose) is a climbing vine cactus species which has received worldwide recognition, first, as an ornamental plant and then as a fruit crop. Its fruit is the most beautiful in the family Cactaceae with a bright red skin studded with green scales and white or red flesh with tiny black seeds.  The flower is so beautiful that it is nicknamed as Noble Woman or Queen of the Night.  The juicy flesh of the fruit is delicious in taste. It is well established as a new crop in Australia, China, Israel, Malaysia, Nicaragua, Taiwan and Vietnam. In Vietnam, it has become a major export crop, which fetches higher prices than even Durian, the King of Fruits in south East Asia.  The main constraint is that the establishment cost is high due to use of trellises for climbing. The cost of establishment will depend on the type of trellises used, and experience in Sri Lanka shows that relatively cheap trellising is sufficient. The other agronomic practices are easy and less expensive; maintenance cost is low and aftercare is minimal due to fewer pest and disease attacks. Further, the biggest advantage of this crop is that once planted, it grows for about 20 years, and one hectare could accommodate about 800 Dragon fruit plants.

Dragon fruit, commonly known as pitaya/pitahya (Hylocereus sp.) is a  climbing perennial cacti belonging to the Cactaceae family and the subfamily Cactoidea of the tribe Cactea (Raveh et al., 1993). It is a perennial climbing cactus plant native to tropical areas of North, Central and South America. Main countries growing dragon fruit are Vietnam, Colombia, Mexico, Costa Rica, Nicaragua, Thailand and Taiwan. Cultivation also occurs in Australia, Israel and Reunion Island. The European Union and Asia, especially China are the largest import markets of dragon fruits (Vinas et al., 2012).

Drainage - definition

Agricultural drainage is the artificial removal and safe disposal of excess water either from the land surface or soil profile, more specifically, the removal and safe disposal of excess gravitational water from the crop root zone to create favourable conditions for crop growth to enhance agricultural production.

Benefits of drainage

a)It provides better soil environment for plant growth by creating favourable soil aeration conditions.

b)It improves the soil structure and in turn increases the soil infiltration.

c)High infiltration capacity reduces soil erosion.

d)It hastens the warming of the soils and maintains desirable soil temperature, which accelerates plant growth and bacterial activity.

e)It promotes increased leaching of salts and prevents accumulation of salts in the crop root zone.

f)In well drained soils, less time and less labour are required for tillage operations.

Technical Term      Definition

Drainage               Removal and disposal of excess water from agricultural lands is referred as drainage.

SUMMARY

The natural drainage systems are severely affected by the development processes and thus increased in waterlogged and salt affected areas. In major and medium irrigation projects due to inadequate designs coupled with poor management practices has raised groundwater table and in turn sizeable command areas are being affected both by water logging and soil salinization, Water logging and salt problem have been experienced in irrigation projects all over the country. Both adversely affect the growth and the yield of the crops. An area with water table within 2 m from the land surface is called as water logged area. It is potential to water logging if water table is between 2-3 m from the land surface. It has been estimated that around 16.71 million hectare land is affected by salt and waterlogging in India. The drainage is the remedy to these problems for sustainable agriculture.

            Drainage is defined as the natural or artificial removal of surplus ground- and surface water and dissolved salt from the land in order to enhance agriculture production. In the case of natural drainage the excess waters flows from the fields to lakes, swamps, streams and rivers. However, in an artificial system surplus ground or surface water is removed by means of sub surface or surface conduits. Improved drainage create a healthier environment for plant growth, It conserve soil and water; and provide drier field conditions for ease in farm operations for the crop production. Agricultural drainage is must to realize the full benefit of irrigation.

Agricultural land drainage is adopted for removal of excess surface and subsurface water, either from irrigation or rainfall in order to improve the profitability of land use.  Drainage also plays a role in removal of salts from the root zone. Therefore, land drainage is closely linked to irrigation in arid and semi arid regions. India has a long history of practicing irrigation and drainage in its semi arid irrigated regions. During the ancient times in the Indus Valley dams and drainage system were built for cultivation of different crops. The earlier experience of drainage was more concerned with surface drainage because from time immemorial India has been experiencing floods of varying magnitudes.

Geomorphometric analysis is the measurement of the threedimensional geometry of landforms and has traditionally been applied to watersheds, drainages, hill slopes, beaches, and other groupings of terrain features. In particular basin morphometric parameters have received a lot of attention from hydrologists and geomorphologists since watersheds (catchments) have been used for analysis of various physical ecosystem processes, including soil erosion, deposition, runoff, stream discharge, sediment yield, sedimentation of streams, irradiation by sunlight, evaporation, evapotranspiration, and nutrient distribution. The study of morphometric parameters, which include variables such as average basin slope, the basin elongation ratio, compactness ratio, basin relief and stream density. Some parameters, such as slope length or stream sinuosity, can be used to represent both basin and hill slope, or basin and stream channel properties.

The main task before geomorphologists is to use an ideal unit of the earth surface for the study of its landforms. The search for an ideal areal unit, within which the collection, processing, organization and interpretation of the data of the geometry of landform, particularly of erosional origin can be made has been the main aim of the geomorphologists right from Fennemen (1914), Horton (1932 and 1945), Strahler (1956 and 1957), Miller (1953), Chorley (1957), Schumm (1956), Shreve (1966), Singh (1981), Sarkar (1995), Schumm and Spitz (1996), Sharma and Amin (1996), Iqbaluddin et al (1997) and Raj et al (1999).

Q. 1 Which of the following is a correct match?
(A) Mole drain = pump drainage
(B) Vertical drainage = well drain age
(C) Pipe drain = well drainage
(D) Horizontal drain = bio-drainage

Drainage is the natural or artificial removal of excess water from a surface or sub-surface from an area or field or soil or greenhouse. The internal drainage of most agricultural soils in greenhouse is good enough to prevent severe waterlogging. Water logging creates anaerobic conditions that harm root growth in absence of oxygen. Soils need artificial drainage to improve production or to manage water supplies in certain conditions. Though the roots need moisture but they need oxygen too and poor drainage is g result in roots rotting and death of plants.

The irrigation water inside the greenhouse may accumulate and cause anaerobic condition. Similarly plants in pots should not accumulate water. Water should not stand in pots and beds for longer period. If it stays longer drainage is poor and needs to be corrected. It is better to have good drainage system in greenhouses or protected structures.

Besides irrigation rains water seeps in the greenhouse. The drainage system prevents running or its accumulation in low lying portion of the greenhouse. Drainage system in greenhouses is a must for avoiding damage to the crops.

A drainage system is a network of structures, channels, pipes, and natural features designed to manage and control the flow of water, primarily rainwater or surface runoff, away from inhabited areas, agricultural land, and infrastructure. The primary purpose of a drainage system is to prevent flooding, erosion, and water logging, thereby safeguarding public health and property, as well as ensuring the efficient use of land.

Surface Water Management: Surface water, which includes rainfall and other forms of precipitation, needs to be managed effectively to prevent damage to properties and the environment. Drainage systems collect this water and direct it away from vulnerable areas.

Catchments: A catchment or watershed is the area of land where rainwater collects and drains into a specific river, lake, or other water body. Understanding catchment areas is crucial in designing drainage systems because it helps determine how much water needs to be managed.

Protected cultivation of vegetable crops refers to creation of favourable environmental conditions around vegetable plants, offsetting or minimizing the detrimental effects of prevailing or expected to prevail abiotic and biotic factors. In open fields, vegetables face several abiotic and biotic stresses, resulting in lower or poor or no yield. This condition is altered by using different protected structures for cultivation and/or nursery production. Vegetables which are transplanted using seedlings should be produced by raising seedlings under protected conditions. Protected conditions ensure production of healthy seedlings. The use of healthy seedlings ensures better and higher production of vegetables both under protected conditions and open field conditions. Nursery grown in nursery trays can be transported long distances and can wait till field is ready or human resources is available for transplanting. Structures are ideal for production of plug plants/transplants in different sizes of portable trays.

Dried Fruits and Pods

The enchanting beauty and usage of fresh pods or fruits need not end up with the season. They are dried and preserved for years. A colorful array of choice dried fruits are very popular in dried arrangements. There are numerous dried fruits and pods used in potpourri and dried flower arrangements.

Dried Grasses

Grasses are easy to collect to dry and use. When the seed-heads have formed, the grass is cut off just above the soil using a sharp knife. They are allowed to lie in a thin layer in the sun for a day or two, turning them over a few times. They should not be allowed to get too damp. After they are dried they are put into a plethora of uses. Bunches of dried grasses can make a wonderful addition to any home or office.

Flowers and plants are associated with mankind from the dawn of civilization. In the modern era these have become an integral part of human life, as love for flowers and ornamental plants is a common natural instinct in human beings. The catchy flowers glowing and glowing in all their grandeurs with simplicity always make them tempting to wish the season to continue for never ending, but it may be beyond reach of human beings. However, the answer for it could be by producing and preserving ever-lasting or long-lasting flowers and other attractive ornamental plant parts. These are now becoming favorites especially with the adventurous flower lovers across the globe. The beauty and fresh look of cut flowers and cut foliage is generally lost due to microbial activities and biochemical changes thus these are retained only for a few days even by using the best techniques of post harvest management (Datta, 1999). The charm of dried ornamental plant parts can be maintained from a few months to years with lesser cost if protected from the damage of high humidity as in dried flowers, the microbial activities in the aging process come to stand still.

The main characteristics of dried ornamentals are novelty, longevity, aesthetics, flexibility and year-round availability. The dehydrated or dried ornamentals are generally inexpensive and are sought for their everlasting and attractive appearance globally (Smith, 2000). Being largely focused on the qualities of attractive flowers, living plants and plant parts, floriculturists generally pay little attention to dried and preserved flowers and plants. Therefore, these products remained overlooked and underrated throughout the world. These are overlooked in the sense that their considerable economic importance is generally unrecognized and these are underrated in the sense that their aesthetic contribution is largely discounted. In contrast to other areas of floriculture including post-harvest management, relatively very little public funded research and development projects were undertaken on the dried flower industry across the globe (Joyce, 1998). This has slowed the pace in optimizing the dehydration technology and quality of the produces. Privately funded research and development work has sustained, but such findings are usually kept secret and limited information are available to the common man. Thus, this component of floriculture industry has remained ill defined with respect to the processes, products and organizations in the developed and developing countries. As we see in major cut flower crops, there are defined standards available for judging the quality, however these are lacking in dried ornamentals. There is an urgent need to start war- footing efforts and awareness on the dried ornamentals to attract greater public support to conduct concentrated research and development with more professionalism in the trade of these products.

Dried Petals

Many types of dried petals are used for making pot pourii eg., land lotus petals, rose petals, mahogany petals, lily petals and lotus petals. Flowers are dried for everlasting beauty. They add an elegant touch to the room and are dried for everlasting beauty. Preserving blooms is a wonderful way to preserve memories and enjoy long lasting splashes of color. Many flower parts are used in dried form. A vibrant and thrilling range of dried petals are used to embellish greeting cards, folders, books, and other personal belongings.

Driftwood is wood that has been washed onto a shore or beach of a sea or river by the action of winds, tides, waves or man. It is a form of marine debris or tide wrack.

In some waterfront areas, driftwood is a major nuisance. However, the driftwood provides shelter and food for birds, fish and other aquatic species as it floats in the ocean. Gribbles, shipworm sand bacteria decompose the wood and gradually turn it into nutrients that are reintroduced to the food web. Sometimes, the partially decomposed wood washes ashore, where it also shelters birds, plants, and other species. Driftwood can become the foundation for sand dunes.

Introduction

In the process of creating a hole in the metal surface through a drill, we use a drilling machine. We use a tapper shank and parallel shank to tie the drill to the drill machine. We can also use a drilling machine to do extra experiments i.e., tapping rimming counter shrinking and counterboring. In simple language, we also say that a, it is a machine which is wildly used over world for making a circular hole in various metal workpiece for making desired design or structure.

Crop Water Requirements

In designing an irrigation system, the primary objective is to know the water requirement of crops. Water requirement of crops are determined either by f ield cultivation or by estimation through commonly used empirical formulae such as Blaney Criddle, radiation, Penman or pan evaporation method.

Definitions

Crop water requirement or evapotranspiration (ETcrop ): It may be defined as the rate of evapotranspiration of a disease free crop growing in a field of not less than one hectare under adequate fertility and water supply so that full productive potential can be achieved in prevailing environment. Evapotranspiration requirement of a crop refers the ETcrop and expressed in mm/day.

Reference crop evapotranspiration (ET0 ): It is the rate of evapotranspiration from an extended surface of 8 to 15cm tall green grass of uniform height, actively growing, completely shading the ground and not short of water. ET0 may be computed by using the empirical formulae and meteorological data for the specific period.

Introduction

Drip irrigation is an efficient method of application of water at the plant bottom at a rate nearly equal to the consumptive use rate of the plant, thereby minimizing the conventional water losses like percolation, runoff and evaporation from soil. It is a process of slow application of water on, above or beneath the soil by the surface, sub-surface, bubbler, and spray or pulse system. Fertilizer can also be applied with the drip water. Emitters or applicators are placed closed to the plants and used to spray water in the form of drops, tiny streams or miniature spray. In the drip system water applied from the point source advances in all direction in the soil outward from the source. Drip irrigation is essentially a low rate, low pressure, frequent and long duration application of water in plants root zone area.

Drip irrigation is also called as localized irrigation, trickle irrigation, daily f low irrigation, diurnal irrigation, drop irrigation, sip irrigation, and micro irrigation. A particular name is being popularized in any area depending on the choice of the people of that area. The International Commission for Irrigation and Drainage (ICID) has recommended the term micro-irrigation while the American Society of Agricultural Engineers (ASAE) has preferred drip irrigation. In India it is told as drip irrigation.

Micro irrigation normally called as drip irrigation was introduced in early seventies. Drip irrigation is one of the advanced methods of irrigation, by which water can be supplied directly into the root zone of the soil to achieve considerable saving of water through high water use efficiency, compared to surface irrigation method where water use efficiency is low due to losses in the water distribution system in the field. In micro irrigation method, water supplied at slow rate that is 1.0-2.0 kg/sq cm to the root zone of an individual plant through lets called emitters or drippers fitted with laterals pipes and filters at pump side. The success of micro irrigation is proven and efforts are being made in promoting the same extensively among the farmers in arid areas.

The hot arid regions of India are spread over about 31.7 million ha area mainly in the States of Rajasthan, Gujarat, Andhra Pradesh, Punjab and Haryana, which inhabit on an average 61 persons per square km making up a population of nearly 20 million peoples. The Indian arid zone is characterized by high temperature and low and variable precipitation which limit the scope for high horticultural productivity. However, these conditions greatly favour development of high quality production in number of fruits such as date palm, ber, pomegranate, citrus, aonla, bael, grapes and, guava. The optimized technologies and inputs could increase the existing low productivity. It is now realized that there is a limited scope for quantum jump in fruit and vegetable production in the traditional production areas. The amelioration of the extreme conditions is also considered vital for life support to the inhabitants of this area. The recent awareness regarding the potential of these ecologically fragile lands for production of quality horticultural produce has not only opened up scope for providing economic sustenance for the people of this region, but also for bringing new areas to increase production through horticulture.

The scope of expanding water supplies through the development of water resources is very limited since suitable dam sites are fewer, development costs are prohibited, and environmental concerns are too strong. This has led to the realization that saving on the use of water is an option for expanding the water supply.

2.1 Introduction

Water is the most precious gift of the nature and it is also the most crucial element for sustainability of the life in the earth. India is the largest user of freshwater in the world. India’s total water consumption alone is the higher than any other continents. The Agricultural sector is the largest consumer of water followed by the domestic sector and the industrial sector. The role of irrigation water as one of the most essential inputs for crop cultivation can’t be denied. As a traditional productive input, it ensures production by acting as an agent of insurance against inadequate and inconsistent monsoon. Ultimately the outcome provides agricultural production stability. Thus, irrigation is of prime importance in cultivation of vegetable crops as it ensures favourable water balance within the root zone in addition to natural precipitation. It fulfils the crop- water demand and improves the crop production and effectiveness of other agricultural inputs. It is also an important limiting factor of crop yield, because of its association with several factors of plant environment, which directly influence the crop growth and development (Yaghi et al., 2013). The various irrigation methods under different system of irrigation differ with regard to extent of control, timeliness and adequacy of supply of irrigation water for crop cultivation. Consequently, the economic benefits and the costs due to these irrigation methods vary among different irrigation systems. The dominant method of irrigation practiced in large parts of the country is surface irrigation (basin, border and furrow) where the entire soil surface is almost f looded without considering the actual consumptive requirements of the crops. Frequent over or under irrigation create the problems of water stress or water logging leading to reduced irrigation efficiency (less than 30%).
