Information is a basic resource essential for individual and organization in order to survive and succeed in society. Floriculture is a technology driven industry needing technological advancement. The new technologies that are being developed at various places the world over, needs to be disseminated through proper and quick linkage between the researchers and the beneficiaries i.e. the farmers. This demand can be met out by information technology. Information is data put into a meaningful and useful text. Today, information technology (IT) is a metaresource and computers are being used as a metatool and a metamedia.

COMPONENTS OF INFORMATION TECHNOLOGY

An information technology architecture is an integrated framework for acquiring and evolving IT to achieve strategic goals. It has both logical and technical components. Logical components include mission, functional and information requirements, system configurations and information flows. Technical components include IT standards and rules that will be used to implement the logical architecture.

Input devices: The advent of touch screen monitors has made it possible to develop user-friendly interface for farmers. It is now possible to capture and store good quality graphics and video clips with digital cameras.

Output devices: Output devices like monitor screen, printers and plotters, data projectors support high resolution and good quality output.

Processors: The processing speeds of computers have improved a lot these days. At present, Intel P-IV based processors @ 3.3 Ghz are available in the PC range.

Storage devices: To store substantial information at local level. Capacity of 40 GB and higher are common in hard disk devices, besides floppy disk drives and CDs; all making it possible to transfer large amount of data to locations which cannot be connected to networks quickly.

Biotechnology can be defined as utilization of materials and methods for benefit of mankind by the utilization of microorganisms and biological agents. It is an area with a tremendous potential in solving basic problems of food, fibre, fuel and medicines in developing countries. According to the office of the Technology Assessment of the US Congress, biotechnology can be defined as any technique that uses living organisms to make or modify a product, to improve plants or animals or to develop micro organisms for specific uses. Flower industry has always increasing demand for new forms, colours and types of flowers. Biotechnology has made significant advances in the improvement of ornamental crops and development of new varieties has great potential to be utilized in future. Utilization of this technology can be done in floriculture under two broad subheads viz., tissue culture and genetic engineering.

TISSUE CULTURE

The major commercial utilization of tissue culture has been micropropagation, which is an alternative to vegetative propagation. Micropropagation permits true to type multiplication of a desired genotype using in vitro culture techniques. Micropropagation process can produce a large number of propagules in a relatively short time and space under controlled conditions. It has already revolutionized production process of several nurseries. The dream of multiplying disease free plants in required quantity on the specified time schedule in an industrial way has become true due to micropropagation. Some of the important floricultural crops that are successfully propagated in vitro in Indian laboratories are given below with their explant source:

Carnation: Leaf segments, internodes, petals

Gerbera: Leaf, petiole, flower stalk segments

Gladiolus: Inflorescence stalk, leaf sections

Orchids: Epidermal peelings, leaf segments, root tips

Rose: Internodal segments, petals, leaf segments, immature embryos, root segments

Flower growing, once used to be a gardener’s activity has today transformed into an astounding business proportion. Globally, more than 140 countries are involved in cultivation of floriculture crops. The global floriculture trade stands at US $ 60 billion with an annual growth rate of 10-15%. But the picture is not all that rosy. The extensive use of pesticides especially in greenhouse grown crops is threatening workers health and safety, besides disturbing environment and may also affect consumers health.

Gaston Dorren and Niala Maharaj, authors of “The Game of the Rose” noted that floriculture consumes more pesticides than any other agricultural sector. Floral workers suffer the brunt of the trade’s pesticide use. About 60% of Colombian flower workers (the sprayers and handlers) suffer from headaches, nausea, impaired vision, rashes and asthma, reports Pesticide Action Network, North America. A study published by the Netherlands ‘Ministry of Social Affairs and Employment’, reports that Dutch floral workers are exposed to pesticide concentrations of up to 60 times the amount considered safe.

Dr. Marion Moses of the San Francisco-based Pesticide Education Center says that many of the pesticides in use are highly toxic. “One of the chemicals widely used in greenhouses for flowers is temik (aldicarb), and that has caused serious problems”. Methyl bromide, an ozone destroyer and a category I acute toxin, among the most dangerous toxic substances known, is also heavily used in Latin America and the U.S. on flower crops. According to a 1997 EWG (Environmental Working Group) study, California-grown roses have 1000 times the level of cancer causing pesticides as comparable food products. Consumers are buying roses that, toxicity levels suggest, should be handled by workers wearing protective gear. Testing the leaves and petals of roses from California, New Hampshire, Colorado, Canada and Colombia, EWG found two probable human carcinogens, three Category I pesticides (the most hazardous) and three neurotoxins at up to 50 times the amount allowed in food.

INTRODUCTION

Zinnias are popular in flower gardens because of their variable coloured blooms and their ability to withstand hot summer temperatures. They are easy to grow from seeds. Plants come in many colours, shape and size adapted well to most growing conditions. Out of about twenty species, these are some eight to ten species of zinnia known to the gardens, but only few of them have become favourite and that abundantly deserves the pre-eminence. They have attained position as one of the most splendid of annual flowers. Most varieties are prolific bloomer, making them excellent for landscape. They are also available as compact varieties suitable for hanging baskets, window boxes and containers. Recently, new hybrid zinnia cultivars have attracted attention as a cut flower crop. There are at least hundred varieties in the diversity of flower colour and types. Some with flower heads upto 15 cm across. The colour of zinnias are white, cream, green, yellow, apricot, orange, red, bronze, crimson, purple and lilac with stripped, speckled and bicoloured flowers. An important variety of zinnia is Coccinea or Scarlet-rayed. This variety became popular after its existence in 1829 and was thought much of for its brilliant colour and stately habit. During the fifty years that have elapsed since it appeared, the flower has been in all characters and now posses a race of perfectly double zinnias, the flowers of which show no central disc, but are perfect rosettes of exquisite form and of every shade of colour except blue. There is not a more striking instance of floral advancement, accomplished by systematic selection, than is afforded by zinnia, which is at once one of the largest and long standing of many good and cheap annual flowers.

INTRODUCTION

Zantedeschia is commonly known as Calla lily. The other names are Arum lily, Aroid lily, Lily of the Nile and Pig lily. They are mainly grown for their attractive, large flower spathes, which are usually produced in the spring and summer and also for their variegated and spotted foliage. They are grown in large quantities by commercial growers because they are commonly used for decoration in Easter and throughout the spring and early summer months. It grows very well in open conditions in warm climate. Regular gardeners may have their bloom in winter, spring or early summer depending upon the temperature conditions maintained in the greenhouse.

Zantedeschia is an excellent cut flower and last a long time in water. There are various species, which produces different coloured flowers. The flower spathes of calla or arum lily (Zantedeschia aethiopica) are white, the spathes of the yellow or golden callas (Z. elliottiana) are yellow, whereas the pink calla (Z. rehmannii) produces lavender red, rose red, violet red or pink spathes. The white arum (common calla) forms large colonies in marshy areas ranging from the coast to an altitude of 2250 m above mean sea level. Thus, they may exist in humid, salt laden air at the coast and freezing, misty mountain grassland at high altitudes and as a result, are very versatile in the garden. The leaves of the calla are very interesting in that they contain water stomata, which can discharge excess water by a process known as guttation. This prevents logging and enables calla lily to grow in wet conditions.

INTRODUCTION

Tulips are one of the most popular and widely grown flowering plant. Tulip is a main stay of spring gardens providing abundant flowers in vivid and vibrant spectrum and colours. It is first among bulbous ornamentals due to its attractive colours and exquisite flowers. Tulip is the national flower of Turkey and tulip motifs feature prominently in Turkish folk arts. The first European cultivation of the tulips as a garden flower occurred in the Netherlands in sixteenth century. In the following century, the early enthusiasm for the new flowers triggered a speculative frenzy now known as tulipomania. The Netherlands and tulips are still associated with one other. Tulip festivals are held in the Netherlands and in North America every May. A number of bewitching cultivars grown to perfection in a large variety of delicate and brilliant shades have developed tulip cultivation into a great bulb growing industry. Tulips are not only widely cultivated for cut flower production world wide but also grown for pot culture, in beds, borders, formal and informal location. They are also suitable for growing in orchards, lawns, rockeries and wild gardens.

The word tulip industry is dominated by the Dutch tulip growers. There is 10,000 hectare of tulip bulbs grown in the Netherlands. About 70 per cent of tulip bulbs cultivated are for forcing for flowers with 30 per cent for pre packs for gardens. The world market for bulbs has been buoyant for the past ten years. Production has been increasing at the rate of 6-8 per cent per annum and the market has expanded in line with this growth. In the Netherlands, three quarters of the total bulbs produced are exported, with the highest percentage going to the United State followed by Germany. In India, tulips are gaining popularity among the flower growers owing to congenial climate in hilly areas. Particularly in Kashmir valley, production of cut flower is increasing. Some area has been increased in Himachal Pradesh. It can also be grown successfully in other hilly parts of the country like Uttaranchal between 1300 to 3000 metre above mean sea level.

INTRODUCTION

Among the important ornamental bulbous plants, tuberose occupies a very prominent position. In the orient, where ‘white’ goes for virtue and purity, tuberose flower is much adored for its prettiness, elegance and fragrance. It is commercially grown as cut flower, loose flower as well as for its potential in perfume industry.

The flowers of tuberose are used for artistic garlands, floral ornamentals, bouquets and buttonholes. The long flower spikes are excellent as cut flowers for table decoration when arranged in bowls and vases. They remain fresh pretty long time and stand long distance transportation and fill a useful place in the flower market.

Plants of tuberose can be used in landscapes; in all-white gardens or with other plants. Variegated varieties with golden or yellow striped leaves are very attractive and these varieties are suitable for garden beautification. Potted plants can be put in decorative containers and used for entranceways and interiors.

INTRODUCTION

Stock or Gilly flower is an annual or biennial plant flowering in terminal clusters. It exists as both single and double forms and is valued for fragrant flowers that can be used as fresh or dried cut flower. Stocks are a most valuable race of garden plants for they are easy to grow and can be in bloom during the greater part of the year. They are excellent pot plants for the greenhouse in winter and spring and provide good cut flowers. Flowers are well arranged on a long column and the colours are variable from white to rose, crimson, purple, yellow, mauve, pink, etc. Seeds of stock are aphrodisiac, bitter, diuretic, expectorant, stimulant and are used as tonic. An infusion has been used in the treatment of cancer and when mixed with wine, it has been used as an antidote to poisonous bites. The highly fragrant flowers are used as a garnish, especially with sweet deserts.

INTRODUCTION

In many cultures, fresh cut flowers are deeply symbolic, conveying the message of nature to man. In recent times revolutionary changes have been seen in Indian floriculture sector which is due to the introduction of various annuals from abroad. Snapdragon too is the one of the relatively recent introduction in the field of cut flowers. Now-a-days, snapdragons are usually grown as annuals, though traditionally they are cultivated as perennials. Due to its curious shape of flowers, which resemble a dog, rabbit or dragon, it is popularly called as snapdragon, dog flower, bunny rabbit or bunny mouth. Snapdragons are one of the most popular and widely grown garden annuals. It is ideally suited for beds, pot, edging, window boxes, herbaceous border and rock gardens. Tall cultivars can be used among the shrubs, at the background of the annuals like hollyhock, larkspur, etc. in mixed borders or with herbaceous plants. The intermediate cultivars are very useful for bedding and potting purposes. Both these types are excellent for cut flower production. The dwarf cultivars are good for edging and bordering formal beds. The dwarf hybrids are suitable for covering the patches in rock garden. They are used in floral arrangements and in bouquets too. Their production for cut flower purpose began with the introduction of a winter flowering cultivar Chevoit Maid, followed by several F₁ hybrids with desirable cut flower qualities. The F₁ hybrids are grown all the year round. Flowers have good keeping quality, as they remain fresh for 6-7 days. Snapdragon has also been reported to have medicinal importance. It has diuretic and astringent properties and have been employed for the treatment of scurvy, liver tumor and ulcers.

INTRODUCTION

The rose is one of the oldest flowers in cultivation and most popular of all garden flowers throughout the world. It is one of the nature’s beautiful creations and is universally known as the Queen of Flowers.

Th e cultivation of th is f lower h as developed with the distillation of rose as mentioned in Ayurveda by Charaka around 100 A.D. At present, it has become the most important commercial flower. A large quantity of rose flowers is used for decoration purpose. Beside, it has been growing for centuries for the extraction of its essence. The rose water is frequently used for flavouring sweets and other food articles as well as for sprinkling over guests on festive occasions. Hips of some rose species are rich in vitamin C while its petals are used for preparing Gulkand and Pankhuri.

Domestic demand for roses has two components; the demand for stemless roses supplied by field grown roses and demand for stemmed roses, mainly grown under protected conditions. In most parts of India, rose flowers throughout the year, in a succession of flushes of blooms, without having any true dormant period. Good quality blooms are produced in winter when local market demand is good. There is a growing demand of value added floral extracts in world market, hence there is great scope for commercial cultivation of rose for production of floral extracts.

The fragrance of rose is said to be the only fragrance that never tires the human olfactory system. Export of rose water started in 8^th century from Iran and later in 9^th century from India and China, mostly to Arabian countries. Rose cultivation was introduced as an industry in Turkey in 17^th century and later spread to other countries like Egypt, Morocco, France, China, India, etc. About 80% of rose flower are utilized for rose water, 10% for attar, 1 to 2% for pankhuri and remaining for manufacture of gul-rohan and gulkand. Rose oil is used primarily as a fragrance component in pharmaceutical preparations e.g. ointments and lotions and is extensively used as a fragrance ingredient in perfumes, creams and soaps. Food products in which they are used include beverages, frozen dairy desserts, sweets, baked foods, gelatins and puddings.

INTRODUCTION

Orchids are the most beautiful flowers in God’s creation and have conquered the cut flower industry all over the world during the last few decades. They are most pampered of the plants, occupy top position among all flowering plants and are valued for cut flower production and as potted plant. They are known for their beautiful flowers, which exhibit an incredible range of size, shape and colour, long life of flowers on the plants and an amazingly long keeping quality which no other plant can claim.

Orchids are excellent for garden and can be grown in beds, pots, baskets, split hollows of bamboo pieces, etc. They are also suitable for interior decoration and remain fresh for many days. Before their aesthetic qualities were exploited, orchids were grown for their tubers which were considered as aphrodisiac. The leaves of Vanda roxburghii have been used against rheumatism in older days in India. Habenaria, a terrestrial genus of orchid also possess medicinal properties. Vanillin produced from Vanilla planifolia is used in flavouring industries. Orchids are used in indigenous system of medicine, particularly Ayurveda. Many of the orchid species contain alkaloids, which are important secondary metabolites. From Dendrobium nobile dendrobine and nobilonine are extracted. Similarly, laburnine from Liparis bicallosa, malaxine from Malaxis congesta and phalaenopsine from Phalaenopsis mannii are extracted. Pseudobulbs of Cymbidium madidum and Dendrobium speciosum are used as food.

Orchid industry in India is not as old as the cultivation and trade of other flowers. Our position in export market is very low as compared to south-east Asian countries like Thailand, Malaysia and Singapore, where orchid growing has become a multi-million dollar industry.

INTRODUCTION

Narcissus is a hardy or tender herbaceous perennial, growing from bulbs and seeds. In India it is commonly called Nargis. The splendid yellow and white flowers of the narcissus alone could make April and May month of delightful sweetness in the garden. Shakespeare mentioned Narcissus again and again as common symbol of the English spring. Narcissus are highly suitable for rowin in beds ots under the deciduous trees, window garden, etc. They are very good cut flower and are sold in the market. The bulbs of the European species are used in folk medicine as these are believed to possess the purgative, dermal and depurative properties. Few species are used for extraction of essential oil in France. There is often confusion as to whether the name narcissus or daffodil should be used. Popular thought attached the former name to the sweet scented tazetta or poet narcissus and the latter to the small wild Lent Lily which is still to be found massed in the wood and open pastures. Today daffodil usually refers to long trumpet and large flowered garden forms while, all the rest are narcissus. In the simplest words, the species of this are called narcissi, although the trumpets, which have trumpet (corona or cup) as long as or longer than the surrounding petals are usually called daffodils.

INTRODUCTION

Marigold is an important flower crop and constitute as one of the five most commonly cultivated and used flower in urban and rural India. They are extensively used for making garlands, beautification and other purposes i.e. pigment and oil extraction and thera eutic uses A art from these uses marigold is a widely grown plant in gardens and pots. It is highly suitable as a bedding plant, in a herbaceous border and is also ideal for newly planted shrubberies to provide colour and fill the space. French marigold is most ideal for rockery, edging, hanging baskets and window boxes. Flowers remain fresh for 4-5 days at room temperature and are used for religious offerings and social functions. Recently marigolds are grown commercially for extraction of carotene pigments mainly xanthophylls. The carotenoid extracted from petals are added to poultry feed for intensification of yellow colour of egg yolk. Lutein which is the major constituent of xanthophylls is used for colouring food stuffs. Purified extract of marigold petals containing lutein dipalmitate is marketed as an ophthalmologic agent under the name adaptinol. Dietary carotenoids can be used to treat cancer and photosensitivity diseases.

Marigold leaves contain a distinct odoriferous oil. Wild marigold (Tagetes minuta) oil has valuable and precious essential oil which is used in high grade perfumes and cosmetics. Ketones present in the oil are base material for synthesizing aroma chemicals. Marigold essential oil has bronchodilatory, tranquilizing, anit-inflammatory as well as insect repellent activities. The floral extract of marigold is used for treating eye diseases and ulcers.

Lotus is the foremost symbol of beauty, prosperity and fertility. According to Hinduism, within each human inhabiting the earth is spirit of sacred lotus. It represents eternity, purity and divinity and is widely used as a symbol of life, fertility, ever-renewing youth and to describe feminine beauty especially the eyes. Egyptians considered it a symbol of rebirth, since it closes in the evening and falls to the water, then reopening again in the morning, thus emulating the behavior of the sun. All lotuses are day-bloomers that open early in morning and close by mid afternoon for three successive days, with first flower closing earlier. It possesses an amazing ability to flourish in a variety of environment ranging from clear ponds to muddy marshes. The exquisite flowers with long herbaceous stalk arise from the rhizomatous stems and a flat and peculiar seedcase at its center.

Lotus, the national flower of India, has been a part of Indian culture, religion and history from ancient times. It is considered sacred not only by the Hindus of India but also by the Buddhists of China and Japan. To early Egyptians, a lotus bud or Sesen was a symbol of rebirth. Lotus is offered to Goddess Lakshmi and is considered as her symbol. Besides, lotus has found place in one of the postage stamps in India. Every year some prestigious awards are given to the distinguished personalities of the country like Padmashree, Padmabhushan, Padmavibhushan and Swarna Kamal (Golden Lotus).

INTRODUCTION

Lily is one of the most important ornamental bulbous plants. It comprises one of the distinctive flowers in form, appearance and colour. The flower stems of lily are long and sturdy with luxuriant foliage and it has longer vase life. Lilies are very useful flowering plants which can be planted in any location as they do well in the bed or border with other perennial. Almost all varieties of lily are suitable for planting in combination with other plants and in front of tall shrubs. They look very charming in large clusters for mass effect. Shorter varieties are planted in containers. Lilies may be planted in the perennial border, preferably with the plants having ample foliage. They seem to have fascination for some companion and thus can be grown with other flowers in the garden. The bulbs of some varieties of lily are edible and somewhat bitter in taste but fairly pleasant when properly cooked. In China, bulbs of tiger lily are prefered as food due to its specific taste. Lilaline, an alkaloid is also found in the flower of some lilies. Lily has several medicinal properties. The bulb is diuretic, emmenagogue, emollient and expectorant. The flowers are carminative. They are used to strengthen the eye lid muscles and are commended in the treatment of myoptic astigmia.

Among the lilies, two groups have been evolved through extensive improvement and referred as coloured lilies and extensively grown for cut flowers and other popular type is generally grown for garden display in India. Asiatic and Oriental lilies are leading cut flower group and in the international market. It is dominated by the Netherlands. An oriental hybrid cultivar Tiara is developed. It is true pollen free lily, excellent for bouquets. Oriental and Asiatic hybrid lilies are compact, with plant height of 60 to 150 cm that bears many flowers. Spikes of 10 to 15 cm flower diameter that may point up, out or down. Blooms may be red, pink, orange, yellow, lavender or white in colour.

Jasmine is one of the first plants that come to mind when one thinks of sweet fragrance. A single jasmine vine can perfume an entire room or garden. Jasmines have adorned the gardens of central Asia, Afghanistan, Iran, Nepal and many other tropical and sub tropical countries. India exports jasmine flowers to the neighbouring countries like Srilanka, Singapore, Malaysia and also the Gulf. Jasmine contributes substantially to the national economy and annually about Rs. 20 crores worth of flowers are produced in India.

Plants are grown both as shrub and climber. Flowers and flower buds are used for making garlands, bouquets and veni and for religious offerings. Jasmine oil extracted from the flower is highly valued as it is used in manufacturing perfumes, cosmetics, creams, hair oils, soaps and shampoos. Flowers are used in jasmine tea or herbal or black tea. As a medicinal plant, jasmine has traditionally been considered an aphrodisiac and calmative. In India, it is grown in different states especially Tamil Nadu, Karnataka, Kerala, Uttar Pradesh, Bihar and West Bengal because their flower and floral buds are in great demand.

INTRODUCTION

Irises are among the easiest of perennials to grow, providing an abundance of beauty with minimum care. Iris means ‘rainbow’ because they come in various colours. These are herbs with sword like leaves and roots are generally rhizomatous, although in a few species they are bulbous. The majority of garden irises are hybrid, often complex ones, whose parentage is obscene. Bulbous irises are more important in commercial horticulture, with over 50 cultivars, but dominated almost equally by two i.e. Ideal and Professor Blaauw which together account for over 70% of the area grown in the Netherlands. Regular irises make great cut flowers with their tall, sturdy stalks. Dwarf varieties are suited for flower beds and rock gardens.

Certain irises were at one time widely used in the manufacture of perfume, also has been widely used in folk medicine, mostly because of the fragrance of its dried roots which are used in the preparation of face powder and dentifrices. Commercially, the powder is known as Orris-root or Orris. The rhizomes of certain irises also have edible value.

It is one of the most important traditional flowers of India mainly used as a potted plant, loose flower, cut flower and as border plant in the garden. Chrysanthemum cinerariifolium inflorescences are of considerable importance in the manufacture of pyrethrin insecticides. The leaves of Chrysanthemum balsamita become leathery on drying and can be used as bookmarks. Fresh young customary leaves can be used in salads and to add a balsam flavour in beer, soups and bread. Now programmed blooming of chrysanthemum all the year around is possible by environmental manipulations.

INTRODUCTION

China aster is one of the most popular annual flowering plant grown throughout the world. Among annuals it ranks next to chrysanthemum and marigold and is grown mainly by marginal and small farmers. It can easily be grown in the open fields and lath houses for the roduction of cut flowers Cut asters last long and are used in vases and floral decoration. When asters are grown in large mass, they make very showy bedding plants and are valuable for filling up the gap in mixed herbaceous border. The dwarf types are put in front and the taller behind.

Some strains are used as pot plants, while dwarf cultivars are suitable for edging and window boxes. The prominent colours of flowers are blue, violet, lavender, rose, white, etc. In tropical and subtropical countries aster is extensively grown for bedding and cut blooms during winter month and spring. China aster is one of the most important traditional flowers in India and has maximum use for traditional purposes. The commercial importance of China aster is increasing in India especially in Karnataka, Tamil Nadu, West Bengal and Maharashtra.

INTRODUCTION

Carnation is one of the most beautiful and commercially important flower crop. It occupies prime position in the international cut flower trade and is a good commercial cut flower for internal market as well. Carnation flower can easily withstand long distance transportation as it has an excellent kee in ualit Its cut flowers with a 70 to 90 cm stem length, healthy and bright flower commands a better price. Carnations have a sweet fragrance and also commercially utilized for extraction of oil in France and the Netherlands. The volatile oil of carnation contain 40% benzyl benzoate, 30% eugenol, 7% phenylethyl alcohol, 5% benzyl salicylate and 1% methyl salicylate. It is used only in sophisticated perfumes. Carnation flowers round the year and have wider colour range like red, salmon, pink, purple, yellow, orange, bicolour, stripped, white and fancy combinations. The major break through in carnation flower industry was evolvement of cultivar William Sim. This cultivar was produced in 1938 to 1939 by William Sim of the USA. From this red variety there have been mutations to white, pink, orange and different variegated forms. The first genetically modified carnation variety Moon Dust is released in Australia by a plant biotechnology company Florigene. There are several distinct types of carnations and each of these can be grown in cooler parts of the plains and at medium to higher elevation. Carnations are cultivated under glasshouses in temperate countries and in the open or in semi-protected conditions under polythene cover, in both tropical and sub-tropical regions. Because of strong emphasis on quality in both export and domestic market, commercial production of spray and standard carnations is considered as a crop of protected conditions. Before being planted in the greenhouse, the crop must be carefully planted so that it will meet the demands of the international markets.

INTRODUCTION

Strelitzia is known as Bird of Paradise. The uniquely shaped flower of this exotic tropical resembles a head of bird and due to its brilliant orange and blue colour and unusual form, it resembles not any bird but a bird of paradise. Its another common name, Erane flower is another bow to its exotic avian shape. Fantastically handsome flowers aside, this is also a very attractive foliage plant resembling the related heliconia in vegetative appearance. Due to the brilliant colour and unique appearance of the flower, it is exceptionally popular as a cut flower which appears periodically throughout the year. Therefore, it is cultivated in different countries for cut flower production to supply it in local and export markets. Commercial production of cut bloom is done in California, Hawaii, Israel, France, South Africa and Japan.

Bird of paradise occupies a place of pride in the garden and is an important choice for landscaping. It is grown in backyard and also for mass effect. Plants of strelitzia can be used in the landscape in a low growing ground cover to enhance the beauty of garden. They serve well anchoring island beds when surrounded by lower growing annuals or ground cover. It can also be used in shrub borders and adaptable beauty is perfect for home and commercial interiors.

INTRODUCTION

Anthuriums are a perennial herbaceous plant of great beauty and grown either for their showy cut flowers or for their attractive foliage. They are valued for their colourful long lasting spathe and spadix. The cultivars contribute elegance and attractiveness, which are pre-requisites for quality and floral design. It is also known as Flamingo flower or Flamingo lily. What is usually considered the flower is comprised of a colourful, modified leaf (spathe) and hundreds of small, botanical flowers on the pencil like protrusion (spadix) rising from the base of spathe. Anthurium have been cultivated from many decades for cut flower production. Since the mid 1980’s its popularity has increased dramatically and has now become a popular addition to many foliage growers. The economic life span of anthurium is around 6-8 years.

In India the cut flowers of Anthurium andreanum are cultivated for considerable length of time although still in small scale. Commercial viable production should be estimated of approximately 5 ha, which is far below the market demand. The anthurium is getting increasing popularity in the Indian market and therefore, most of the locally produced anthurium is sold in the domestic market against reasonable prices. Its export possibility appears very promising as the flowers are already exported to the Middle East. The development of main flower distribution centre in Dubai offers important possibilities for Indian floriculture.

INTRODUCTION

Alstroemeria is still a relatively new cut flower in the world market and the interest in it is continuously growing. This increase is due to the fact that this flower crop is fairly easy to cultivate and does not require special demands. Its flowers are beautiful and have a very long vase life. It is commonly known as Brazilian Parrot lily or Peruvian lily or Incan lily or Red Parrot Beak or New Zealand Christmas Bell. In the Dutch market, it is an important cut flower and gaining popularity in the international market. Recently some efforts have been made to popularize this flower in India as cut flower and pot plants by some multinational companies. Its cultivation has been started around Bangalore, Pune and Hyderabad. Recently it has been introduced in Palampur, Solan, Srinagar and Ooty, to popularize this crop among growers for domestic and export markets. This crop can be grown successfully on the hill areas of Uttaranchal. Mid and high hill areas are very suitable for growing it. Alstroemeria is a typical greenhouse crop, but can be grown in open under mild environments with partial modifications. It is a potential, low volume and high value crop for hill horticulture.

In India, the agricultural research and technology generation are supported in five agro-ecosystems, viz. irrigated agro-ecosystem, arid agro-ecosystem, rain-fed agro-ecosystem, coastal agro-ecosystem and hill & mountainous agro-ecosystem. Each system with its varied socio-economic and agricultural features, demands appropriate technologies to augment the productivity of various enterprises with sustainable development and economic returns. Unfortunately, the conventional development efforts, which often follow “top-down” approaches in planning and implementation, don’t address the constraints and developmental potentials of farm household systems in a comprehensive way. To overcome these shortcomings, reversal of approach, i.e. from “Top down” to “Bottom up” is recommended. This can be achieved through site-specific assessment and refinement of technologies with farmer’s participation where the farmers of different agro-ecosystems have right to plan, implement and own their developmental projects (Johnkutty et al., 2001).

Introduction

Programme for self-employment of the poor has been an important component of the anti-poverty programmes implemented through government initiatives in the rural areas in India. The Swarnjayanti Gram Swarozgar Yojana (SGSY) is the major ongoing programme for the self-employment of rural poor at present. The programme was started with effect from 01.04.1999 after restructuring of Integrated Rural Development Programme (IRDP), and allied programmes namely Training of Rural Youth for Self Employment (TRYSEM), Development of Women and Children in Rural Areas (DWCRA), Supply of Toolkits in Rural Areas (SITRA) and Ganga Kalyan Yojna (GKY) and Million Well Scheme (MWS). Govt. of Orissa have launched ‘Mission Shakti’ programme in 2001 with an aim to have at least three lakh WSHGs by the end of 2008. By the end of March 2008, 3.73 lakh WSHGs have been formed under Mission Shakti (Annon, 2007-08). SGSY has contributed substantially in carrying forward the Mission Shakti activities in the state. A study was conducted by the Center for Management and Development, Thiruvananthapuram for concurrent evaluation of the implementation of the SGSY. It was established that the performance of SGSY in Assam, M.P., Orissa, West Bengal and Bihar was the lowest among the major states (Anon, 2002-03). SGSY is implemented in a very deterministic and top down manner, ignoring the participatory approach that is envisaged in the design. Good governance for poverty alleviation programme seems to be more of rhetoric than reality (Shylendra and Bhirdikar, 2005). The Ministry of Rural Development, Govt. of India has set guidelines for successful implementation of the scheme within the framework of targets under each head. As per the guidelines, all the states are directed to fulfill the targets. After 10 years of implementation of the scheme, an evaluation of the programme in district level and state level is in dire need. Hence, it is attempted to evaluate the physical and financial achievement of the SGSY programme operated at Orissa.

Introduction

At the very outset, the varied aspects which govern the agricultural scenario in India have been taken up. Basically, India is a land of diversity and Indian climate defies an easy generalization. It comprises a wide range of weather conditions prevailing across a large geographic scale existing in the midst of varied topography. A systematic analysis reveals that Indian climate can be partitioned into six major climatic subtypes, ranging from deserts in the west, to the alpine tundra and glaciers in the north, to humid tropical regions supporting rainforests in the southwest and the island territories. The landform pattern is also found to be widely varying over places. Interestingly, tIndian soils can be divided into six categories, namely, alluvial soils, regular soils, red soils, laterite soils, mountain soils as well as the desert soils. Being a populous country whose sixty percent of the population earns its livelihood on agro-based incomes, directly or indirectly, it is important to review the robustness of the system followed in the actual practice in the Indian scenario towards the process of raising crops which ultimately feed more than hundred crores population. The review reveals that the agricultural production and farm incomes in India are frequently affected by the natural disasters such as droughts, floods, cyclones, storms, landslides as well as the earthquakes, and, indeed, the susceptibility of Indian agriculture to these disasters is compounded by the outbreak of epidemics and man-made disasters such as fire, sale of spurious seeds, fertilizers and pesticides, price crashes etc. As a sequel, the farmers are severely affected through the loss of production of agricultural crops and consequently, the loss of farm income due to occurrence of such events, and it is no denying that the management of or coping with such factors remains beyond the control of the farmers.

Introduction

Developments in both hardware and software sectors of computer science raised high expectations and strong vision to solve number of problems in all sectors of economy. Introduction of personal computers (PC) in 1970’s created vision of paperless offices, simplified computing, automated process control, management information system, expert system etc. Initially, it had greater impact on agricultural research and development in developed countries in the form of Information and Communication Technology (ICT). Growth of companies with promises to provide specialist software to farmers and growers during 1980’s is a clear indicator of the high expectation and visualization of ICT in the field agricultural research and development. A review of agricultural software availability and use has been made by an international team in 1997 called FARMSOFT. This review covered on eight countries viz. Belgium, France, Germany, Israel, Italy, Portugal, Spain and The Netherlands. It was found that in 1996 out of 1315 software related to agriculture, 39% were in category of management, 26% were in category of animal husbandry, 8.9% in category of crop production, 7.0% in category of machinery and process control, 0.1% in category of irrigation and 19% in others category. Comparison of change in software inventory in 1996 with respect to 1994 revealed that there is around 15% growth in the agricultural software development. The higher positive growth was in the category of management software (38.40%) followed by animal husbandry (10.45%) and others (10.44%). However, highest negative growth was observed in the category of irrigation (-163.15%) followed by crop production (-53.85%) and machinery and process control (-30.95%). This indicates that overall agricultural software inventory was growing but while growth in the software related to agricultural management was sufficiently high, there was sharp decline in categories of irrigation and crop production. This change in pattern may be attributed to saturation of software and bottlenecks due to limitation of related technological innovations, socio-economic adoption and infrastructural facilities.

Introduction

Technological advances of the past two decades have profoundly reshaped and enhanced all aspects of medical research and practice. Concepts, methodologies, tools, and applications of medical informatics with the latest technique and approaches are essential for every one pursuing in the medical IT field. Improvements in healthcare delivery in recent years are rooted in the continued industry-wide investment in information technology and the expanding role of medical informatics. The main goal of this chapter is to collate and provide innovative and creative ideas so far published on healthcare in one article for use by the researchers, practitioners and other related with health care system for improving communication environments in health and to explore all new technologies in medical informatics and health care delivery systems.

Medical Informatics can be defined as a discipline concerned with all aspects of understanding and promoting the effective organization, analysis, management, and use of information in health care (American Medical Informatics Association, 2007). In recent years, medical informatics has become a well-recognized branch of medicine.

Introduction

The advancements in the field of informatics, biology and allied fields of technology led to the emergence of an inter-disciplinary field known as ‘Bioinformatics’ (Kumar 2006, Madhan Mohan 2006). Explosion of knowledge in the field of biology and generation of new information (data) needs collection, storage, organization, integration, analysis, simulation of biological data and a faster distribution among the scientific workers (Mehrotra et al. 2005). The advent of super computers, high speed computing and development of algorithms for data formatting, assists in the storage of data at the site of origin and distributed through the hyperlinks in world wide web (www).

The vast field of Bioinformatics is beyond the scope of this article. However to elucidate the concepts that led to the the development of Bioinformatics vis-à-vis is given in brief before explaining the new and emerging area of ‘fluxomics’.

Introduction

Aquarium fish keeping has become increasingly popular in industrialized countries and has been rated as the second biggest hobby and the most popular type of pet (Oliver, 2001). The National Pet Owners Survey 2007-08 revealed that 142 million freshwater and 9.6 million salt water fish were kept as pet in the USA alone (APPMA, 2008). The growing interest in aquarium fish has resulted in steady increase in aquarium fish trade globally. Today, with a turn over of US $ 9.0 billion a year and an annual growth of 8.0%, production of ornamental fish is an important business activity as well as one of the most popular hobbies in the world (Yanar et al., 2008).

ABSTRACT

Coastal aquaculture in India is synonymous with shrimp culture since shrimp has a pronounced presence among the basket of commodities produced in the sector. In coastal aquaculture, maximum area is under shrimp culture due to its high profitability, ready marketability, premium price and unlimited export demand. Since the growth of shrimp has showed significant fluctuations in terms of area, production and productivity over time, this paper aims to seek and use appropriate methodology for computation of growth rates. Accordingly, the present study utilized nonparametric regression method for computation of growth rates. Results indicated that the methodology has been successful in extracting required information from the data set. The analysis revealed that growth of Indian shrimp farming is largely governed by east coast states. Potentiality of west coast states remains grossly underexploited. Broad results also indicate that growth rate is higher in commercial shrimp farming states compared to traditional farming states. Shrimp farming being a livelihood option for small and marginal farmers of the deprived sections of the population of a developing country, like India, consistent yield is more important than substantial growth in yield in shrimp farming.

Introduction

Water hyacinth, Eichhornia crassipes, is such an aquatic plant that needs hardly any introduction. This aquatic plant is considered as nuisance weed found floating freely on fresh water bodies, proliferates aggressively and therefore, spreads like wild fire. It can infest all types of water bodies, chokes waterways, canals, channels, dams, and thus damages potential water resources. Evidently, two plants produces 300 offspring within 23 days only and under ideal environment, 10 plants can multiply to 6 lakh and may cover an acre area within a period

Introduction

Mangroves are the special group of plants or the ecosystem in a holistic scence on the inter-tidal coastal areas, edges of the islands and major estuarine mouths. The frequently tidal inundated forests on coastal areas, wetlands and the inter-tidal zones of sheltered bays or shore lines, estuarine mouths, sides of the tidal creeks, backwater, lagoons, marshes and mud-flats of the tropical and sub-tropical regions of the Globe are the major mangrove habitats or zones. Mangrove ecosystem form an important ecological asset and economic resources of the coastal marine environment. These mangrove ecosystem is the most productive ecosystem, which can efficiently fertilize the sea and estuarine water and also physically protect the coastal zone, estuarine mouth from frequent natural calamities and vitally serves as the breeding ground, nursery and grazing place of diverse species of fish, shrimps, prawns, crabs and vast group of other marine and off-shore species.

Introduction

Aquaculture has developed quickly over the last three decades to turn into important economic activity world wide. It has been attracting heavy investment due to the availability of sound technologies and limitless potential for export especially shrimp. There are several forecasts on demand for aquatic foods and it is expected that it will be 183 million tonnes by 2030. As the capture fishery production is stagnating at around 90 million tonnes, aquaculture is seen as the only alternative to bridge the widening gap in demand and supply. Globally, Landings from worldwide aquaculture has increased 10-15 % per year in the last two decades and this growth was due to the combined effects of scientific farming, availability of infrastructure facilities, changing consumer preferences and export market potential to developed countries.

Shrimp farming is relatively new and its introduction on a commercial scale can be traced to the early seventies. Despite the recent introduction, one third of the world shrimp production is from farmed shrimp. The shrimp producing countries are found in all regions based on FAO statistics including Europe and Middle East. The major to five shrimp producing countries are China, Thailand, Vietnam, Indonesia, and India. The future increase in world aquaculture production will be driven by China with South Africa, Latin America, the Caribbean and the Europe providing small increases.

Introduction

Fisheries sector, a sunrise sector in India, has recorded a faster growth than that of crop and livestock sectors (Kumar et al., 2006). The sector contributes to the livelihood of a large section of economically-underprivileged population of the country. It has been recognized as a powerful income and employment generator as it stimulates growth of a number of subsidiary industries and is a source of cheap and nutritious food besides being a foreign exchange earner (Ayyappan and Krishnan, 2004).

With the changing composition pattern, emerging market forces and technological developments, it has assumed added importance in India. It is undergoing rapid transformation and the policy support, production strategies, public investment in infrastructure, and research and extension for fisheries have significantly contributed to the increased fish production. Particularly, after the mid-1980s, the development of carp polyculture technology has completely transformed the tradition backyard activity into a booming commercial enterprise. The aquaculture in the East Godavari delta region prospered with good yields and export driven demand. The paddy belt of the area rapidly converted into aquaculture hotspot owing to high economic benefits. But in recent years the dwindling of aquaculture and frequent losses caused and forced the farmers to withdraw from the once profit driven occupation. Apart from economic analysis, the motive behind this investigation is to find the efficiency of the farmers and the determinants. This will be useful in finding the lacunae in existing system of culture and will address necessities for shifting to new alternative.

Introduction

Cashew is an important horticultural crop. It has gained status of commercial crop from that of a forest component through technological advancements with respect to propagation, production and management. This has been possible as a result of increasing demand for raw cashew nuts and enhanced interest for its commercialization. The demand is mainly due to its good quality protein, unsaturated free fatty acids, rich blend of minerals and water-soluble vitamins, which altogether contribute an excellent dietary supplement. It is being cultivated by as many as 28 countries in Asia, Africa and Latin America

Introduction

The Andaman and Nicobar Islands popularly known as the Bay Islands are situated 1200 Km away from Indian mainland and are well known for their wide range of biodiversity.The dreaded tsunami hit the island on 26th December, 2004 and it destroyed livelihood of thousands of people. CARI on a limited scale initiated process of restoration of livelihood by technological interventions with generous funding by DBT under project entitled “Integrated Rehabilitation of tsunami affected people through technological intervention in the Andaman & Nicobar Islands” in the adopted villages of Manjeri, Manglutan and Guptapara. (Three situations). A total 56 ha has been affected by tsunami in the adopted villages. Following three situations occurred after tsunami and for each situation appropriate technological interventions were taken up.

Introduction

With the advent of modern agricultural technology, especially during the period of the Green Revolution in the late sixties and early seventies, there was a continuous surge for diversified agriculture, primarily on economic considerations. The changes in cropping pattern, however, are the outcome of interactive effect of many factors which can be broadly categorized into the following five groups-

Resource related factors like irrigation, rainfall and soil fertility.

Technology related factors viz. seed, fertilizer, and water technologies on one hand and marketing, storage and processing on the other.

Household related factors like food and fodder requirement as well as investment capacity of the farmers.

Price related factors covering input and output prices and economic policies that affect these prices.

Institutional and infrastructure related factors pertaining to farm size and tenancy arrangements, research, extension and marketing systems and government regulatory policies.

Introduction

Research and development (R&D) is one of the main components to tackle the problems persisting or likely to take place in future. Priority areas of research are depending upon the overall situation and requirements of the problem under consideration. Under these broad areas, topic of interest for research may be varying at different geographical level from household to nation or global. If it is addressing vast geographical area like states, nations, regions and/or global, there may be many individuals/groups/institutions are working over similar type of problems. With the growing communication facilities and rising fund requirements, collaborative research programmes emerged to provide effective and economic solution to the problem with respect to time, money and manpower etc. Earlier, it was limited to high priority areas like defense and long run planning of the nations or kingdom at nation or state level. Declining environmental conditions and biological diversity became global concern in seventh decade of twentieth century. To tackle this problem, The United Nations Conference on the Human Environment (Stockholm) resolved to establish the United Nations Environment Programme (UNEP) in 1972. Further, to speed up the progress, global community through world leaders had identified two burning priority areas during conference United Nations (U N) Environmental Programme Rio de Janeiro, Brazil in 1992, well known as Earth Summit. One of those two priority areas was Biological Diversity. To address the issues at global levels, The Convention on Biological Diversity was signed by party nations, which was later ratified by the 187 countries. India is also one of the signatory nations and need to fulfill some time bound commitments. Moreover, later, importance of biodiversity and germplasm has been underlined by different forum at regional and global level for its present and future values in the life of human kind. Countries and various geographical regions are now becoming more and more aware about its judicious exploitation, conservation and sustained higher output over period of time.

Introduction

Pulse production in India has fluctuated widely with no long-term trend, leading to a steady decline in per capita availability per day, i.e. from 60.7 grams to 33.40 grams during 1951 to 2001, while its average requirement is about 65 gram per day per head. The pulses used to serve a low cost food to meet the protein requirement of a large sector of people in India. But, the pulses are becoming out of reach for the common people of country because of its continuing shoring prices. A Technology Mission on Pulse production was launched by Government of India in 1986-87 as a special drive to increase the pulse production in the country. The vision of Technology Mission of Pulse is attaining self reliance in pulses for household nutritional security and sustainability of the production system. The mission statement was to increase Pulse production from existing (IX plan) 131.4 lakh tonnes to 162 lakh tonnes; Productivity from 594 kg/ha to 702 kg/ha and per capita availability of pulses from 35 g to 40 g per day at affordable price. Unfortunately, the country has not been able to achieve self-sufficiency in the pulse production. During the last 40 years, the acreage under pulse crops and its production remained almost between 21-24 million hectares and 10-15 million tonnes, respectively. Consequently, the country has had to depend on import of pulses every year to meet the part of its shortage. The National Commission of Agriculture had estimated that the country should plan to produce about 25 million tonnes of pulses by the end of 2000, but we could achieve only about 14 million tonnes. Presently, the area and the production of pulse crops account for about 18.50 and 7.20 per cent (2003-04) of total area under foodgrains and total food grains production in the country, respectively.

Logical Framework Approach (LFA) is a framework for designing change process, monitoring progress and evaluating impact. It is a powerful tool for project design, management, assessment, follow up and evaluation of projects. In designing change process, monitoring progress and evaluating impact, ordering the change process in a logical sequence where inputs or resources identify as necessary means for performing activities are very important. Specific activities are then identified because they result in outputs which are necessary to achieve objectives. The two terms i.e.; log frame and logical framework approach are sometimes confused by many. The log frame is a document whereas the logical framework approach is a project design methodology. LFA originally developed by the American Defense Department and was first formally adopted as a planning tool for United State Agency for International Development (USAID) by the end of 1960’s and today it is being used, in one form or other and with different names, by major organisations in the field of development co-operation and private industry. Among these are British DFID, the OECD expert group on Aid Evaluation, ISNAR International Service for National Agricultural Research, Germany’s GTZ and the Inter-American Development Bank. It has also been widely adopted by NGOs, though not without reservations and concerns by some. In the 1990s it was often mandatory for aid organisations to use the LFA in their project proposals.

Introduction

The acute food shortage was a major challenge in confronting the development of the country after independence with rapidly increasing population. Massive financial assistance of credit and subsidy under various rural development programmes unveiled by government could not yield desired impact on poverty and unemployment. The benefits of farm research did not reach the resource poor farmers. Several researchers indicated that the devolution of democratic decision-making at the village level was lacking.

The major task of bridging the gap between farmers and the scientific knowledge is in the hands of extension workers who should act as “conveyer belts” in communicating appropriate scientific knowledge and skills already available to the farmer in a smooth and acceptable form and in securing the adoption of these improved techniques. They must assess the intentions prevailing in the minds of rural people, their relationships and interactions, their groups, their institutions, their organizations and the culture, which influence the behaviour at large. They need to understand their motives, reactions, receptivity to new ideas, hidden resources of rural people and social and cultural obstacles prevailing in the society with their active participation.

To elucidate the hidden facts from the well-knit social, cultural and behavioral patterns, a family of approach known as “Participatory Rural Appraisal (PRA)” techniques is widely employed to understand the existing farming situations, problems, and opportunities in the rural areas. PRA techniques can also be used in evaluation and impact assessment in agricultural and allied enterprises and projects that can indicate the success and failure to plan for better future.

Introduction

Impact assessment is the process of identifying the future consequences of a current or proposed action. It is used to ensure that projects, programmes and policies are economically viable, socially equitable and environmentally sustainable. Programme Monitoring and Evaluation (PME) efforts are critical issues in management of agricultural research and development (R & D). In times of fiscal constraint, more emphasis is placed on accountability and programme effectiveness. As a management tool, PME is an integrated approach that incorporates the viewpoints of clientele, policy-makers, researchers and donors to address the intended goals. Public and private support to research will depend largely on efficiency issues and ability to reckon with multiple objectives, ranging from food security to sustainability, poverty alleviation, gender issues, export, etc. The PME of agricultural R & D projects is critical when the intended R&D has multiple outcomes. Monitoring and evaluation (M&E) of development activities provides government officials, development managers, and civil society with better means for learning from past experience, improving service delivery, planning and allocating resources, and demonstrating results as part of accountability to key stakeholders (World Bank, 2004).
