Introduction

India is the largest producer of pulses in the world, both in quantity and variety. But, presently, India is one of the largest importer of pulses. India imported pulse grains upto a tune of approximately 4000 crore rupees during 2006-07. It accounts for about 20 per cent of the total import bill during 2006-07. This is because of the green revolution (quantum jump in cereal production) accompanied with changes in the infrastructures and incentives including input supplies and price support systems in favour of major cereals. It altered the traditional cropping pattern against pulses with decades of emphasis on research as well as production in superior cereals coupled with a near total neglect of the rainfed areas, pulses were driven out of not only the irrigated areas, but also the rainfed farming and were relegated to the marginal lands. Further more, the weak infrastructural support for input supply, credit and marketing in the rainfed areas, the traditional home of pulses, also adversely affected the prospects for pulses. A vicious circle of low input use and low output thus got built in. Lack of processing and marketing facilities in pulses also contributed its share to the woes of pulse growers. The increasing shortage of pulses, resulted in the need for more and more import which, in turn has dampened the speed of rejuvenation of pulses sub-sector of agriculture sector.

The net per capita availability of pulses has fallen from 60.7 (1950-51) to 33.4 g (1991-92). On the contrary, the daily per capita availability of cereals has registered an increase from 334.2 (1950-51) to 443 g (1991-92). It leads to increase in the pulses/cereal ratio from 0.18 to 0.08 g i.e., by 55 per cent. This is despite the increases of 24.36 per cent in area; 61.71 per cent in production and 29.93 per cent in production. It is significant to note that almost all these increases had taken place during 1950-51 to 1960-61. The area, production and yield of pulses have either stagnated or declined since then. This stagnation of pulse production and productivity should be viewed seriously not only from the point of security and quality of food for our people, especially the poor and the rural population, but also from the soaring import bill, imbalance and distribution in the cropping pattern and resource allocation among various sub-sectors of agriculture.

MUTATION BREEDING

Mutation refers to sudden heritable change in phenotype of an organism or permanent change in the number, kind and sequence of nucleotides in genetic material, while individuals showing these changes are known as mutants. Mutation was first discovered by Wright in 1791 in male lamb which had short legs. Hugo de vries coined the term mutation. In crop improvement the breeders are always look for wide range of variability and stabilization of desirable traits. Mutation breeding is very useful in inducing new variability, which is an essential requirement of any plant breeding programme. The modern day cultivars are the resultants of various breeding techniques like selection, hybridization, tissue culture and mutagenesis including some biotechnological tools. Novelty in commercial traits like colour, size, shape, length, post harvest life of flowers etc. are always valued and preferred by consumers. Mutation breeding by exposing planting material with irradiation has play vital role in inducing novelty in a number of flower crops.

TYPES OF MUTATION

Based on occurrence

(1)Spontaneous mutation: Occur spontaneously in nature and not present in sufficiently high frequency and spectrum.

(2)Induced mutation: Artificially produced by the treatment of various mutagenic agents and present in sufficiently high frequency and spectrum

Intellectual Property Rights (IPR) are legal rights, which result from intellectual activity in industrial, scientific, literary and artistic fields. These rights safeguard creators and other producers of intellectual goods and services by granting them certain time-limited rights to control their use. Protected IP rights like other property can be a matter of trade, which can be owned, sold or bought. These are intangible and non exhausted consumption. The term “intellectual property” denotes the specific legal rights which authors, inventors and other IP holders may hold and exercise and not the intellectual work itself (Chadha, 2013). Intellectual property rights are essentially territorial in nature so, where registration is necessary, for patents, registered designs and trademarks, these will not exist in other countries unless registration has been sought and obtained there.

IP protection is crucial for a sustainable contribution of plant breeding and seed supply. Breeding new varieties of plants, which are developed after contributing number of years to the selective inheritance of traits which provide improved yields, higher quality and better resistance to such plant varieties requires a substantial investment in terms of skill, labour, material and economic resources. However, a new variety once released could in many cases be readily reproduced by others so as to deprive its breeder of the opportunity to benefit adequately from the investment made. Thus, an effective system of plant variety protection (PVP) is a key enabler for investment in breeding and the development of new varieties of plants or improving existing plant varieties, encourage importation of foreign varieties, promote exportation of plant varieties provide access to information of the created products and the methodology of creation for the enhancement of social welfare and generally benefit the market place. An international system of IPR protection for plant varieties expands these benefits by facilitating access to new varieties created in other states (Gautam et al., 2012).

Intellectual property is usually divided into two branches: (i) industrial property and(ii) copyright and the rights which neighbour upon copyright. The principal categories of industrial property are: patents, trademarks, geographical indications, industrial designs and trade secrets. Industrial property according to the 1883 Paris Convention for the Protection of Industrial Property is to be understood in the broadest sense and to apply not only to industry and commerce proper but also to agricultural and extractive industries and to all manufactured or natural products including wines, grain, tobacco, leaf, fruit, cattle, minerals, mineral waters, beer, flowers and flour.

China aster (Callistephus chinensis L. Nees) belongs to family Asteraceae. It is a half hardy and branching annual. Its generic name Callistephus is derived from two Greek words “kalistos” meaning beautiful and “stephos” meaning a crown alluding the large colourful flower heads. Plant is erect having hispid-hairy branches (Bailey, 1963). It is propagated through seed. It is cultivated as cut flower both in the field and under protected condition in temperate countries (Post, 1956 and Warren Auman, 1980). Whereas, in India it is widely grown in Karnataka, Tamil Nadu, West Bengal and Maharastra for cut as well as loose flower production (Janakiram et al., 2001).

ORIGIN AND DISTRIBUTION

China aster is originated from China. Several literatures also stated that China aster is native to China and Japan (Anon., 1950, Bailey, 1963 and Cockshull, 1985). The evolution of China aster has remarkable variations. The present day aster has been developed from single form of wild species, C. chinensis, a plant native to China. The plant was introduced in Europe in 1731 by Jesuit Missionary R.P. d Incarville.

The original plant had single flowers with two or four rows of blue, violet or white ray florets. The first change in the flower type had been the prolongation or development of central florets which lead to quilled flowers. Much original work to improve the plant was done by French. Later the British followed suit with breeding programmes. Most of the recent improvements are the work of American breeders. French florists contributed much in development of double forms. German scientists also evolved many doubled cultivars. These asters were known as German asters because the first great advances in the evolution of the plant were made in Germany and the seeds then used came largely from that country. The comet types introduced in 1886 or 1887 subsequently replaced the quilled types. With the introduction of new branching types by James Vick in 1893, the USA became the main centre of development of this plant as well as for the production of seeds. Since its introduction into Europe, it is grown in almost all the countries of the globe as a garden annual. A good amount of work on China aster on improvement and growing practices has been done in India (Singh, 2006).

Freesia is ornamental flowering plant belongs to family Iridaceae subfamily Ixioideae. Freesia is named after a physician and botanist from Germany named “Friedrich H.T. Freese” (1795–1876). Dr. Christian P. Ecklon, a collector of plants from South Africa, named the flower after his friend and student. Modern freesias are known as Freesia x hybrida and cultivated for cut flowers. Freesia is grown for two purposes i.e. cut flower and pot plant.

It is excellent cut flowers because of its appealing shapes and found suitable for various types of arrangements and bouquets. Wide range of colour increases its beauty. Hence, its flower demand increased dramatically in recent year in global market. Forced freesias are grown as pot plant. Colours in freesias consist of pink, red, orange, yellow, blue, lavender, cream and white. Some flowers are multicoloured and possess several variations of colour within the same bud. Because of their delectable fragrance, Freesias have been drafted as a vital ingredient in many fragrance oils. Freesia fragrance oils are utilized for many oil burners and vaporizers. It is used as an essential fragrance in potpourris. Freesia essence oil is high grade essence oil. This is because it is undiluted, alcohol free, and long lasting. The oil is used for aromatherapy to scent candles, soaps, massage oils, bath oils and perfumes.

ORIGIN AND DISTRIBUTION

Freesias are South African in origin. Most species were found in the Cape Province area in southern Africa and two others were found just north of the equator in a tropical climate and even in Sudan. Freesia x hybrida is the name of modern Freesia.

In 1866 Freesia was described as a distinct genus. Freesia alba was first described in 1878 by G.L. Meyer, and became well known in Europe, as F. refracta var. alba. Gumbleton recognized Freesia alba as a distinct species in 1896, but Freesia alba first appeared in the English nursery trade in 1878 and quickly spread to Europe and North America. It appears to have caused quite a sensation, and appeared in almost every horticultural publication of note in both Europe and America in the years following its introduction. Breeding began immediately after F. alba appeared on the market and continues to this day.

Most of the modern hybrids were first made in the 19^th century from a few species. The genus contains some superbly ornamental and adaptable plants. These range from the lovely, scented Freesia alba and the brilliant red Freesia grandiflora and Freesia laxa, to the bizarre green-flowered Freesia viridis.

Stock or Gillyflower (Matthiola spp.) belongs to family Brassicaceae. It is a hardy annual, biennial and perennial plant, flowering in terminal clusters. Matthiola incana is ornamentally important and grown for various purposes i.e. cut flower, fragrance, pot culture, etc. This species develops a woody base in areas where it grows as a biennial or short-lived perennial, hence the name of stock. Generic name “Matthiola” was given in the honour of “Dr. Pietro Andrea Gregoria Matthiole” (1501-1577), personal physician of Emperor Maximilian of Austria. “Incana” means “hairy or gray-white” in reference to plant leaves. It exists as both single and double forms and is valued for fragrant flowers that can be used as fresh or dried cut flower. 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 colours are variable from white to rose, crimson, purple, yellow, mauve, pink, etc. The highly fragrant flowers are used as a garnish, especially with sweet deserts. Many old names were given to Matthiola incana including stocks, sea stocks, wallflowers and wall or gillyflowers.

ORIGIN AND DISTRIBUTION

Matthiola incana is native to the Iberian Peninsula, France, the Apennine Peninsula, the Balkan Peninsula, the British Isles, Turkey and Cyprus. According to Greuter et al. (1986), four species of Matthiola are known in Sicily and its surroundings: M. fruticulosa(L.) Maire, M. incana (L.) R. Br. & Ait., M. tricuspidata (L.) R. Br. and M. sinuata (L.)R. Br. Unlike its congeners, which only have a single taxon in this archipelago,M. incana consists of three infra-specific subdivisions (Lojacono-Pojero, 1888 and Greuter et al. 1986): ssp. incana (L.) R. Br., which is widespread in other insular and continental Mediterranean enclaves, and the narrow endemics ssp. pulchella (Conti) Greuter & Burdet (confined to the islet of Pantelleria) and ssp. rupestris (Raf.) Nyman, distributed in the surroundings of Palermo (Sicily) and in the Aeolids, the Egadian and Ustica, respectively (Raimondo et al. 1994).

Stock earlier known as Leucoium album or Viola alba was later renamed as Mattiola after Dr. Mattioli, an Italian physician and botanist. This was being grown by the ancient Greeks and was linked for its frangrance. In the wild state, stocks are found in the Mediterranean, Egypt, South Europe and in South Africa and two species, Mattiola incana and M. sinuate are among the rare British natives. Ruth et al. (2009) also reported that Matthiola is widespread in the Mediterranean and Irano-Turanian regions. Both single and double forms were grown in Europe from 10^th century onwards and became popular garden flowers. Apart from its countries of origin, Matthiola incana can be found in Australia, Austria, Bolivia, Bulgaria, China, Colombia, Ecuador, Finland, France, Germany, Greece, Ireland, Israel, Japan, Kazakhstan, Mexico, The Netherlands, New Zealand, Peru, Romania, Sweden, United Kingdom and the United States.

Paphiopedilum is a genus of the orchid subfamily Cypripedioideae and family Orchidaceae. It is derived from Paphos and ancient Greek word “pedilon” means “slipper”. Paphiopedilums are often called “slipper orchids” because of their unique pouch. The pouch traps insects seeking nectar and to leave again they have to climb up past the staminode, behind which they collect or deposit pollinia. Paphiopedilum has a highly ornamental value being the treasure of Orchidaceae. They are easily grown as houseplants and their care is very similar to African Violets.

ORIGIN AND DISTRIBUTION

The genus name Paphiopedilum was established by Ernst Hugo Heinrich Pfitzer in 1886. Ironically, no paphiopedilum occurs on Cyprus- at least not as the genus is understood today. But it was long mixed up with its holarctic relative Cypripedium, which indeed grows in the Mediterranean region. Paphiopedilum was finally decided to be a valid taxon in 1959, but its use has become restricted to eastern Asian species. The genus is native to Indo-Malaysia (South China, Southeast Asia and the Pacific Islands) and India. Paphiopedilum armeniacum is found from China (west Yunnan province) to northern Myanmar. It occurs at 1,600 to 2,000 metres above sea level. It is found growing on limestone hills, in semi-shaded deciduous forest, usually on cliffs above rivers.

SPECIES

Over fifty species of Paphiopedilum have been discovered in the far east from the higher, cooler elevations of the Himalayas, across to China and Southeast Asia and down to the warmer, sea-level regions of Malaysia, Indonesia and the Philippines (Hawkes, 1965). Most species, like Paphiopedilum callosum are terrestrial in nature growing under the shaded and moist conditions of the forest floor (Fitch, 1982). Some species, such as Paphiopedilum niveum are lithophytic found in colonies on the coastal rock formations of the Malaysian islands (Fitch, 1982a). While a few of the larger strap-leaf Paphiopedilum species exposed to the higher light conditions found in their loftier habitats. Paphiopedilum philippinense var. roebelenii and Paphiopedilum lowii provide a strong contrast to such as Paph. lowii, are usually epiphytic Paphiopedilum charlesworthii previously described and serve to illustrate the extent of variation in both plant and flower habit within this genus. Unlike the single-flowered spikes of Paphiopedilum charlesworthii, which are usually around 15 cm tall, those of Paph. philippinense var. roebelenii and Paph. lowii can bear up to a half-dozen flowers and can measure 60 cm or more in length. Paphiopedilums with this kind of flowering habit are referred to as multifloral paphiopedilums (Batchelor). The plants themselves can be quite large particularly in the case of Paphiopedilum lowii, where individual leaves are often well over 30 cm long, though narrow.

Wild relatives of cultivated plants constitute a part of crop genepool, which possess genes that have great potential for their utilization in crop improvement programmes. Wild genepools especially those occurring in biotically disturbed habitats are under threat of genetic erosion and require immediate collection to make use of their wider adaptability, tolerance/resistance to disease, insect-pests, yield, quality attributes and other biotic and abiotic traits. The wild relatives of crop plants occur in all the major phytogeographical regions of India as component of different vegetation types and exhibit variable life forms and habitat specificity. High priority demand is towards collection of those that are at the risk of erosion due to habitat disturbance by manmade/ natural causes and over-exploitation of species for commercial use.

The centres of endemism are also centres of genetic diversity and consequently centres of speciation. Unless suitable conservation methods are applied, important wild relatives of crop plants and rare endemic species in particular have poor chances of survival. Based on the efforts made in the past for collection of diversity in wild relatives of crop plants priorities have been recommended for their conservation on the basis of species status (endemic, rare/threatened/endangered, etc.) and those that have high demand in crop improvement programmes (Arora and Nayar, 1984; Nayar, 1996, 1997; Wiersema and Leon, 1999; Hanelt and Institute of Plant Genetics and Crop Plant Research, 2001).

All economically important species at the risk of genetic erosion require attention for collection and conservation. Highest priority may be assigned to those having highly specialized habitat requirement and those that are endemic/rare/endangered to Indian region. Species producing seeds in large quantity and having easy method of multiplication or conservation are at lower risk than those producing less seed and of the recalcitrant or orthodox types where the storage protocols have been least worked out. Species having short seed viability or low germinability need special investigation.

Importance

The dairy products, which have originated in India, are called indigenous dairy products. The products can be broadly classified in to khoa based and channa based. The importance of the dairy products were known to Indians since time immemorial or it could be roughly estimated to be around five thousand years ago and the development could be considered as an art.

All the states have some area under irrigation. Thus the term ‘irrigated ecosystem’is rather loosely defined, and the states having distinctly large net irrigated area may constitute this ecosystem. Two such areas can be easily carved out i.e., Indo-Gangetic Plain region representing five states namely Punjab, Haryana, U.P., Bihar and West Bengal, and coastal areas of two southern states i.e., A.P and Tamil Nadu. About 56% of the net irrigated area of the country exists in these states, and the cropping intensity is also much higher (144%) as against national average of 132%. With demographic viewpoint also, these areas are densely populated. Of late agriculture in this ecosystem has become unsustainable owing to over-exploitation of natural resources. Studies have conclusively established the superiority and worth of integrated nutrient management in restoration of soil health and sustenance of crop productivity and profits.

The basic concept underlying the principles of integrated nutrient management (INM) is the maintenance, and possibly improvement, of soil fertility for sustaining crop productivity on long-term basis. This may be achieved through combined use of all possible sources of nutrients and their scientific management for optimum growth, yield and quality of different crops and cropping systems. INM is not a new concept, but an age-old practice. Its importance was, however, not realized earlier due to low nutrient turn over in soil-plant system and almost all the nutrient needs were met through organic sources, which supplied secondary and micronutrients also besides major nutrients. INM has now assumed great significance mainly because of two reasons. First, the need for continued increase in agricultural production based on increase in per hectare yields requires growing application of nutrients, and the present level of fertiliser production in india is not enough to meet the total plant nutrient requirement. Second, the results of a large number of experiments on manures and fertilisers conducted in india and other countries reveal that neither the chemical fertilisers alone nor the organic sources exclusively can achieve the production sustainability under intensive cropping systems (Hegde and Dwivedi, 1993). Even the so called balanced use of chemical fertilisers would not be able to sustain high productivity due to emergence ofthe deficiencyofone ormore ofthe secondaryandmicronutrients (Swarup and Wanjari, 2000). The interactive advantages of combining organic and inorganic sources of nutrients in INM have proved superior to the use of its each component separately. The advantages of INM can be broadly enumerated as following:

Limited availability of additional land for crop production, along with declining yield growth for major food crops, have heightened concerns about agriculture’s ability to feed a world population expected to exceed 7.5 billion by the year 2020. Decreasing soil fertility has also raised concerns about the sustainability of agricultural production at current levels. Future strategies for increasing agricultural productivity will have to focus on using available nutrient resources more efficiently, effectively, and sustainably than in the past. Management of the nutrients needed for proper plant growth, together with effective crop, water, soil, and land management, will be critical for sustaining agriculture over the long term. Plants, like all other living things, need food for their growth and development. Growth is the function of various factors like light, carbon dioxide gas, water and mineral nutrients. Plants require 16 essential elements. Carbon, hydrogen, and oxygen are derived from the atmosphere and soil water. The remaining 13 essential elements (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, zinc, manganese, copper, boron, molybdenum, and chlorine) are supplied either from soil minerals and soil organic matter or by organic or inorganic fertilizers. For plants to utilize these nutrients efficiently, light, heat, and water must be adequately supplied. Cultural practices and control of diseases and insects also play important roles in crop production. Each type of plant is unique and has an optimum nutrient range as well as a minimum requirement level. Below this minimum level, plants start to show nutrient deficiency symptoms. Excessive nutrient uptake can also cause poor growth because of toxicity. Therefore, the proper amount of application and the placement of nutrients are important.

Sustainable agriculture warrants a wise management of natural resources and inputs to satisfy human needs in the fast changing scenario while maintaining, if not improving, the quality of environment. Soil as a natural resource is facing more and more serious degradation threats under modern agriculture. Incidence and expansion of multi-nutrient deficiencies in Indian soils owing to inadequate and unbalanced nutrient input through fertilizers is considered one of the major reasons for decline in factor productivity of crops. The problem of soil fertility depletion is spectacular across the soil types and agro-climatic zones, but it is more acute in intensively cropped areas, where annual nutrient removal by the crops often far exceeds replenishments. Recent diagnostic surveys indicate that in several high productivity areas of irrigated ecosystems like, Trans-and Upper Gangetic Plain zones, farmers are resorting to even excessive use of fertilizers, especially N, to maintain the yields at levels attained previously with lower fertilizer application rates. With an unabated deterioration in soil health in general, and soil fertility in particular, and a mounting pressure on finite land resources due to increase in population, the interest in soil fertility and soil health has revived due to several reasons:

Stagnation in growth rates of production and productivity of staple foodgrains - threat to food security

Decline in factor productivity, thus increasing cost of production

Nutrient withdrawals in excess of replenishment

Low nutritional value of food and feed grown on nutrient-starved soils - threat to nutritional security

Poor quality of produce fetching low price - threat to economic security

Rice-wheat is a dominant cropping system in the Indo-Gangetic Plains covering approximately an area of 10.5 million ha. Modern agricultural production practices have emphasized the widespread use of fertilizers as a source of nutrients. The continuous use of high levels of chemical fertilizers over a prolonged period, decline in area under legumes and reduction in the use of organic manures has resulted in soil degradation and environmental pollution. It is estimated that the gap between nutrient removal by crops and addition through fertilizers in India will remain at level of 8-10 million tones per annum. Such negative nutrient balances are depleting the soils of their nutrient reserves resulting in acute deficiencies of nutrients. Integrated plant nutrient supply (IPNS) is an important component of sustainable agricultural intensification. The goal of integrated nutrient management (INM) is to integrate the use of all natural and man-made sources of plant nutrients, so as to increase crop productivity in an efficient and environmentally benign manner, without diminishing the capacity of the soil to be productive for present and future generations. The INM is made up of components which possess great diversity in terms of chemical and physical properties, nutrient release efficiencies, positional availability, crop specificity, and farmers’ acceptability. Since organic manures cannot meet the total nutrient needs of modern agriculture, integrated use of nutrients from fertilizers and organic resources seems to be a need of the time. For INM to make desirable progress and find wide acceptance, nutrient supply packages for important agroecological environments need to be developed. These should be technically sound, practically feasible, economically attractive and socially acceptable. Integrated plant nutrient systems can ensure long-term sustainability of agricultural growth through improvement in soil health and will significantly reduce the needs for chemical fertilizers. The complementary use of chemical fertilizers and organic fertilizers may increase the efficiency of chemical fertilizers in order to maintain a high level of crop productivity. Because of low primary nutrient content and thus the need for large applications per unit area, farmers and policy makers are often reluctant to adopt and promote the use of organic fertilizers. The different components of INM possess great diversity in terms of chemical and physical properties and nutrient release patterns.

Biodiversity is the variety of life in different microbes, animals, plants and their genes present in the ecosystem. Soil provides a vital habitat and environment primarily for microflora such as bactria, actinomycetes, fungi as well as microfauna viz. protozoa and nematodes, mesofauna such as microarthopods, enchytraeids, macrofauna such as earthworms, beetles, termites and millipedes (Gaur 2006a).

Biodiversity and soil are interlinked which interact closely with wider biosphere. Conversely, biological activity is ofprime importance in influencing the physical and chemical conditions of soil (Bardgett 2005). The level of soil biological activity is, therefore, affected by soil type and also depends on the use of management practices which contribute to crop productivity.

Soil biodiversity and soil processes

A majority of soil organisms participate in various processes which are essential for the biosphere. The main ecological function is to decompose organic matter largely derived from the plant and animals residues Which consist of celluloses, hemicelluloses and lignin, and to supply plant nutrients to support growth. These organisms participate in various nutrient cycles and processes such as nitrogen mineralization, nitrification, nitrogen fixation, transformations ofphosphorus, potassium, sulphur, calcium, magnesium, iron and micronutrients (Pankhurst et al 1997). They participate in bioremediation of harmful compounds such as heavy metals and pesticide residues (Gaur 2006 b). They not only maintain physical and chemical conditions of soil, but also regulate emissions / assimilations of green house gases and suppress soil borne diseases and pests

Introduction

Seed spices include group of annuals whose dried fruit or seeds are used as spices. These are characterised by pungency, strong odour, sweet or bitter taste. Coriander, cumin, fennel and fenugreek occupy largest area among the seed spices. However, ajowan, dil, celery, anise, nigella and caraway having secondary place as far as area and production is concerned. Major area under seed spices is in Rajasthan and Gujarat, and other seed spices producing states are Chattisgarh, Madhya Pradesh, Andhra Pradesh, Tamil Nadu and Uttar Pradesh. The seed spices account for about 36% and 17% of the total area and production of spices in country. The export of seed spices from India during 2008-09 was 4.71 thousand tonnes worth Rs. 54914.8 million rupees. The per cent export growth rate during 1995-96, 2000-01, 2005-06, 2007-08 and 2008-09 was 12.0, 11.0, 8.0, 36.0 and 19.0% in terms of value and 13.0, 3.0, 8, 13.0 and 6.0 in respect of quantity, respectively.

Integrated plant nutrient management includes use of organic manure/ compost, bio-fertilizer, chemical fertilizer, green manuring, residue management, legume based cropping system, use of nutrient-responsive varieties, proper method and time oforganic manure and fertilizer application, soil and water management to minimize the nutrient losses occurring through volatilization, denitrification, runoff and leaching. Application of plant nutrients in proper balance form is also a part of Integrated Plant Nutrient Management (IPNS) system. Supply of nutrients to seed spices in appropriate quantities and at the correct times is essential for economically and environmentally sustainable agriculture. Soil organic matter, crop residues and manures play a vital role in the supply of macro and micronutrients and the transformation between the various organic and inorganic forms often control availability, both for plant uptake and loss to the environment (Aishwath and Vashishtha, 2008; Lal, et al., 2009).

1. Introduction

Pummelo is considered as largest fruit among all the Citrus species from the Rutaceae family. It is also known as shaddock, papanus or chakotra. Although C. grandis (L.) Osbeck is more frequently used, however C. maxima (Burm.) Merr. is considered as correct under the International Code of Botanical Nomenclature (Singh and Navneet, 2017). It is considered as one of the four true species (natural, non-hybrid) of Citrus. The ltypical large size, thick rind is one of the causes for slow acceptance of pummelo in international market. However, it is presently considered as important fruit due to presence of various bio-active compounds related with human health and nutrition. The word ‘pummelo’ was originally derived from the Dutch word ‘pompelmoes’. The fruit is also named as ‘Shaddock’ after a Captain Shaddock who was believed to have introduced the fruit in Barbados on an East India Company ship on its way to England in the 17^th century. It is known by different names by different communities residing in India such as chakotra (Hindi), batabi lebu or jambura (Bengali), robab tenga (Assamese), nobab (Manipuri), ser trawk (Mizo), soh myngor or soh bah (Khasi), rabab tasing (Adi), papanas (Gujarati), chakota (Kannada), kambili naranga (Malayalam), pamparapanasa (Telugu), metukki or pampalimaku (Tamil) and bampara (Marathi) [Anon, 2019]. Pummelo can be distinguished from grapefruit by its larger size fruit, thicker albedo and the bunch bearing habit of grapefruit can also be considered for distinguishing it from pummelo (Scora et al., 1982). The crop is believed to have originated from South and Southeast Asia and it is now cultivated in many tropical and semi tropical countries. The top ten world producers of pummelo and grapefruit are USA, China, Mexio, South Africa, India, Argentina, Turkey, Cuba, Brazil and Tunisia (FAOSTAT, 2010). It is also cultivated in in Bangladesh, Cambodia, Chile, Philippines, Vietnam, Sri Lanka and Nepal. There is no report of its commercial cultivation in India till date; rather it is mainly grown in homestate gardens across the country including UP, Punjab, Maharashtra, Tamil Nadu and Karnataka. However, maximum genetic diversity in pummelo germplasm is found in North Eastern Region, West Bengal and Bihar (Singh et al., 2015).

1. Introduction

Valeriana jatamansi Jones is considered to be highly endangered medicinal plant found mainly in northern part of Himalayan region. Although it is also found in all temperate regions of world except in Australia (Jain, 1968; Polunin and Stainton, 1987; Bennet, 1987). It is grown in Himachal Pradesh, northern part of U.P., Sikkim and newly introduced in West Bengal Darjeeling region by us. It is enlisted in the endangered category by IUCN (Kaul and Honda, 2000) and it is enlisted as an endangered species in the national medicinal plant board, New Delhi (www.nmbp.nic.in). The plant was reported to be found in fragmented populations in different places of Kashmir Himalayan hilly region like Dara, Sonamarg, Harwan, Gulmarg, Ferozpur, Pahelgum, Yusmarg, Shajnar (Naqashi and Dar, 1982-86). It is found to be in the margin of extinction from the world though it is widespread in the temperate regions of whole world except Australia (Nayar and Sastri, 1998). Indiscriminate collection of rhizomes from the plants made potential threat of its existence in some previously founded localities (Wyatt, 1981; Nayar and Sastri, 1998; Airi et al, 2000; Nautiyal et al, 2003, CAMP, 2003).

1. Introduction

Cucurbits are group of plants belongs to family Cucurbitaceae which are mostly creeping or crawling in nature and distributed in tropical and subtropical zone of the globe. The family cucurbitaceae has around 120 genera and more than 800 species (Swarup, 2016). It holds the highest rank amongst all other plant families considering number and percentage of species used for human consumption either as fruit of the tender leaves and stems. Cucurbits have diverse daily use such as salad (cucumber and long melon); dessert (watermelon and muskmelon), curry or boil (bottle gourd, bitter gourd, sponge gourd, ridge gourd, summer squash, squash melon, pumpkin etc.); candy (wax gourd); pickles (pickling cucumber, pointed gourd); jam (pumpkin); utensil (bottle gourd), musical instruments (bottle gourd). From plant breeding point of view, the crops are cross pollinated and entomophilies.

1. Introduction

Chirata (Swertia chirayita) belongs to the family Gentiniaceae, a potential medicinal plant used as bitter tonic in treatment of fever and for curing various skin diseases, is a perennial herb and distributed throughout the eastern Himalayan region of India. The plant is a native of temperate Himalayas, found at an altitude of 1200-3000 m (4000-10000 ft), from Kashmir to Bhutan and in the Khasi hills at 1200-1500 m (4000 to 5000 ft). It can be grown in sub-temperate regions between 1500 and 2100 m altitudes. It is used in traditional medicine to treat numerous ailments such as liver disorders, malaria, and diabetes and are reported to have a wide spectrum of pharmacological properties. Its medicinal usage is well-documented in Indian pharmaceutical codex, the British, and the American pharmacopeia’s and in different traditional medicine such as the Ayurveda, Unani, Siddha, Horopathy and other conventional medical systems. This ethno medicinal herb is known mostly for its bitter taste caused by the presence of different bioactive compounds that are directly associated with welfare of human health. The increasing high usage of Swertia chirayita, mostly whole plant, as well as the illegal overharvesting combined with habitat destruction resulted in a drastic reduction of its populations and has brought this plant to the verge of extinction. The increasing national and international demand for Swertia chirayita has led to unscrupulous collection from the wild and adulteration of supplies. The bitterness, antihelmintic, hypoglycemic and antipyretic properties are attributed to amarogentin (most bitter compound isolated till date) 1, swerchirin, swertiamarin and other active principles of the herb. Due to the high demand, this plant is being cultivated in many places of Darjeeling district both for domestic use within India and for exporting purpose. During our roving survey (2011-2014), it was observed that this high value medicinal plant facing a number of diseases (like seedling blight, leaf spot, Leaf blight etc.), ultimately, cultivation of Swertia chirayita is getting hampered. The quality of plant is affected due to the occurrences of diseases as whole plants part being used as medicinal purpose and also affects the marketing scenario; the demand of good quality chirata is increasing at a rate of 10% annually. To harvest the benefit of megabiodiversity zone of eastern Himalaya needs urgent attention to combat the upcoming epidemic of diseases of chirata. Here, we are trying to throw some light related to present status of diseases of chirata and standard management practices.

“Tell me what you eat and I will tell you what you are. The destiny of people depends on the nature of its diet.”

Milk is the only product which is considered nature’s almost perfect food. It is treasure house of unlimited nutrients. It is considered best and ideal food by virtue of possessing almost all the nutritional factors, viz., fats, proteins, carbohydrates, minerals and vitamins. They are not only of higher quality but are present in milk in such form and proportion that their digestion and assimilation in the body is very efficient. Milk also plays a supplementary role in our nutrition. If it is included in our diet it enhances digestion and assimilation of nutrients of other food products. This is the reason that it is kept in high esteem as a food and is called the nectar for living beings.

Milk is the first taste of food for whole mankind. It establishes the mother-infant bond and is a life promoter. Of the many fluids that biology offers milk is perhaps the most versatile in terms of its use– as food, as a growth stimulant and as a defense package to the user. To the infant mammal – be it a mouse, calf or a human child, mother’s milk is more than a source of energy and nutrients. It contains a wide variety of substances that defend the growing infant against infections.

Milk, a perfect blend of nutrition and palatability, plays an important role in preserving mental and physical health. Milk has long been recognized as the most wholesome and complete single food available in nature for health and as a medicine, both preventive as well as curative. Ancient chronicles as recorded in the Upnishads, Puranas and Vedas extol the beneficial and therapeutic properties of milk and milk products. It has been stated that cow milk, dahi and ghee impart knowledge and radiance, cure heart trouble and anaemia besides other bodily diseases.

Milk is a complex colloidal dispersion, the physical and physicochemical properties of which depend on intrinsic compositional and structural factors, extrinsic factors such as temperature, and post-milking treatment.

There is no clear dividing line between physical properties and physicochemical properties. However, physical properties may be thought of as the measure of the bulk behaviour of milk and of how milk interacts with energy, while physicochemical properties are measures of how bulk behaviour and energy interactions depend on the constituent colloidal particles, molecules, atoms and ions in milk.

Knowledge of physical properties is of importance particularly in the technological and engineering design and control of milk processes and processing equipment. Knowledge of physicochemical properties provides the basis for the design of modern methods of milk analysis, determination of milk microstructures and elucidation of the complex chemical reactions that occur in milk.

In the dairy industry measurements of the physical properties of milk and milk products are made to secure data necessary for the design of dairy equipment (e.g., heat conductivity and viscosity) to determine the concentration of a component (e.g., specific gravity to estimate solids-not-fat or freezing point to determine added water), or to assess the extent of a physical or chemical change (e.g., titratable acidity to follow bacterial action or viscosity to assess aggregation of protein micelles or fat globules). The great advantage of physical measurements for such purposes is their speed and simplicity as well as their potentialities for automation.

Use of physical property to measure concentrations or changes in degree of dispersion demands knowledge of the contribution of the several components to that property. Furthermore, the natural range of variation of the property in milks or products is of major interest. The precision and suitability of possible methods of measurement are also of prime importance.

A  disaster  (from  Latin  meaning,  “bad  star’)  is  the  impact  of  a  natural  or man-made event that negatively affects life, property, livelihood or industry often  resulting  in  permanent  changes  to  human  societies,  ecosystems  and environment.  The  event  itself  is  not  a  disaster;  it  is  the  impact  that  is  a disaster. Their possibility of occurrence, time, place and severity of the strike can  be  reasonably  and  in  some  cases  accurately  predicted  by  technological and scientific advances. Hence, we can to some extent reduce the impact of damage  though  we  cannot  reduce  the  extent  of  damage  itself.  Despite  the severe impacts suffered – including trauma, starvation, dehydration, infection, disease and shock-animals are often the silent victims of disasters, and there is a real need around for the provision of effective training and management programmes to ensure that their survival and welfare are adequately accounted for. This demands the study of disaster management in methodical and orderly approach.The World Health Organization (WHO) defines a ‘disaster’ as any occurrence that  causes  damage,  destruction,  ecological  disruption,  loss  of  human  life, human suffering, deterioration of health and health services on a scale sufficient to  warrant  an  extraordinary  response  from  outside  the  affected  community or area (WHO, 1999). It is an event, concentrated in time and space, which causes social, economic, cultural and political devastation and which affects both individual people and communities (Kumar, 1998). 

What is Performance Appraisal?

Performance Appraisal (PA) is the process through which an individual employee’s behaviour and accomplishments for a fixed time period are measured and evaluated. The major purpose of measuring and evaluating is to assess the worth or value of an employee. Performance appraisal is a systematic and objective way of judging the relative worth or ability of an employee in performing his task. Performance appraisal helps to identify those who are performing their assigned tasks well and those who are not and the reasons for such performance.

Milk processing plants involve processing of raw milk into products like market milk, cheese, butter, ice cream, condensed milk, dried milks and traditional dairy products. The by-products processing includes buttermilk, whey and its derivatives. Dairy effluents contain dissolved sugar, protein, fat and minerals. Spills and leaks of products or by-products, residual milk or milk products in piping and equipment before cleaning, wash solutions from equipment and floors, condensate from evaporation processes and cheese trimmings are some of the sources of dairy effluents in a dairy plant. The key parameters are the biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids, total dissolved solids etc. Common dairy waste techniques include grease traps, oil water separators for separation of floatable solids, equalization tanks. Biological treatment consists of aerobic and anaerobic process.

Dairy rearing is central to livelihoods and survival of millions of people of India. It is estimated that approximately 100 million people derive their live hood from dairy rearing as primary or secondary source of income. Dairy related activities help to maintain regular in flow of income for these households. Small farmers in India generate nearly half of their income from dairy and the value of cattle represents a significant part of their wealth, so the death of cattle poses a significant risk and affects farmers’ net worth and income.

a. Type of risks to dairy based livelihoods

Large animal’s are expensive and thus carry higher risk exposure. Dairy losses due to the disease, accident, theft, natural calamity can cause significant losses to these household. Sometimes owners are forced to sell their animals due to loss due to incurable disease/ disorder/ fodder and water scarcity and they are unable to rebuild their stock. Many times animal losses force them into poverty trap from where they are unable to recover.

Risks faced by dairy owner’s dairy dependent livelihoods can be classified into two broad categories

Interest Rate: Provisional Interest rate @ 15.75% p.a. has been taken for evaluation of the project report. However, the exact interest rate will be decided by the sanctioning authority on the date of sanction.

Disbursement of loan: Funds for fodder cultivation and civil construction should be disbursed first. Development of sheds and fodder plots should be completed within 3 months from first disbursement. Then disbursement of 1^st Batch cow (10 animals) will be done. Last disbursement for 2^nd Batch cows (10 animals) should be done after 5-6 months of purchase of 1^st batch cows.

Insurance: The animals and other assets (sheds, equipment) must be insured. Wherever necessary, Risk / Mortality fund may be considered in lieu of dairy insurance.

Management of Calf

Management before birth

    ·    As calf management begins before birth, a few days before the calf is born, the pregnant cow is transferred to a maternity paddock, which should be near the homestead (for closer observation), well watered and free from physical objects.
 
    ·    The signs of imminent parturition (calving) include filling of udder with milk and is turgid, vulva swollen with a string of mucus hanging from vagina.
 
    ·    Insemination records can also be used to estimate the expected calving date.

Vegetables constitute a substantial part of human diet supplying vitamins and minerals, in which other food materials are deficient. India has emerged out as the second largest producer of vegetables in the world. More than 25% of fruits and vegetables are damaged by the attack of insect-pests (Pradhan, 1964).Vegetable crop is damaged by both sucking as well as chewing insect-pests. Sucking pests are aphids, whitefly, jassids and bugs attacking in initial stage whereas chewing pests like borers, infesting in flowering and fruiting stage. Sucking pests may transmit the viral diseases which cause severe loss in yield in tomato and okra crops. About 13-14 % of total pesticides used in the country are applied on vegetables. Average pesticide consumption in vegetables in India around 0.678 a.i. kg/ha. Maximum pesticide usage in chilli followed by brinjal, cole crops and okra. Global agro-chemical consumption dominated by fruits and vegetables, accounting 25 % of total pesticide market. Major insect-pests of different vegetable crops and their management are as follows:
 
Cole crops

Cabbage (Brassica oleracea var capitata) and Cauliflower (Brassica olercea var botrytis L) are grown in cold and moist climate. It is rich in minerals namely iron, magnesium, phosphorous and sodium. Cole crops were attacked by number of insect pests and cause heavy economic loss. The major insect pests are described below along with their management:

Okra Abelmoschus esculentus L.

Cotton Jassid Amrasca biguttula Ishida (Hemiptera: Cicadellidae)

Economic importance: Sucking pest cause damage during May to September. Adults are also found on plants such as potato, brinjal, tomato, etc.

Mark of identification and life cycle: Adults are about 3 mm long and greenish yellow during the summer, acquiring a reddish tinge in the winter. The winged adults jump or fly away at the slightest disturbance and are also attracted to light at night. Females lay about 15-38 yellowish eggs on the underside of the leaves, embedding them into the leaf veins. The eggs hatch in 4-5 days. Nymphs are wedge-shaped and are very active and complete five instars with 3-5 days in each instars. Adult live for 11days.

Nature of damage: Damage to the crop is caused by the adults as well as by the nymphs, both of which are very agile and move briskly, forward and sideways. They suck cell-sap from the underside of the leaves and pass through six stages of growth in 7-21 days. They feed constantly on the plant juice. The pest completes seven generations in a year. Damage symptoms: Injury to plants is due to the loss of sap and probably also due to the injection of toxins. The attacked leaves turn pale and then rust-red. With change in appearance, the leaves also turn downwards, dry up and fall to the ground.

Abstract: Trees are known to reduce growth and yield of crops under their canopy in agroforestry systems through competitive interaction. This chapter describes the mechanism of competitive interaction between Linseed (Linum usitatissimum L.) and Leucaena leucocephala (Lam) De Wit in an alley cropping system. To know the mechanism of competitive interaction in agroforestry, three competition situations are created: crop + Leucaena shrub neighbour, crop + L. hedge neighbour and sole crop. In this study competitive interaction is studied in an alley cropping system having two alley width sizes i.e. 4m and 8m. Sunlight at ground, soil organic C and total N are measured in all the competition treatments at different distances from shrub and hedge neighbors. Sunlight is not reduced in crop + hedge treatment like that in sole crop treatment. Sunlight is reduced in crop + shrub treatment (36 to 82%), being the highest in 4m alley and the lowest in 8m alley size. Soil organic C is high but total N is low in crop + hedge and crop + shrub neighbour than in sole crop treatment. Comparing the two competitive treatments (crop + hedge and crop + shrub neighbour) it is observed that growth rate (42 to 55%) and crop yield (71 to 72%) are reduced greater due to aboveground than belowground competition. Belowground competition is 3.6 times greater in 4m than in 8m alley, suggesting that spacing is an important factor, which regulates tree/crop competition so does the crop yield reduction in an agroforestry system.

ABSTRACT
Increased environmental pollution and high demand over supply for conventional fossil fuel sources have led to the exploration of other renewable energy sources. Out of the potential alternatives, methane has come up with a promising unconventional fuel source. Several technologies have been developed to establish methanation, including biomethanation, chemical methanation and gas-to-liquid technology. Several factors like process parameters, catalysts and reactors have been studied for process optimisation and making methane production commercially viable. Although methane as a greenhouse gas is a contributor to global warming, its combustion produces relatively ‘environment friendly’ gas CO₂, and H₂O. The released CO₂ is fixed into biomass by plant through photosynthesis process. Only rarely does methane combustion produces CO when combusted in an oxygen-limited condition. Thus, methane production and combustion are carbon neutral process. This chapter focuses on the application of methane as a source of alternate energy. Various technologies used, recent advances and challenges faced in methanation process are discussed.

ABSTRACT
The annual accumulating organic wastes generated through milling, brewing and various other agro-industrial and agri-processing activities in India amount to about 500 MMT. Most of these contain three major structural biopolymers, viz., cellulose, hemicellulose and lignin, a large proportion of which is carbohydrate and phenolic in nature. Massive accumulations of this kind of recalcitrant biomass not only deteriorate the environment, but also generate huge amount of potentially useful materials. Biological transformation has globally become increasingly popular among researchers and academicians in treating agricultural, industrial, organic and toxic wastes these days. About 60% by weight of the original pineapple fruit in forms of peeled skin, core, crown end, etc. resulting from the pineapple processing remains unutilised being discharged as waste, causing disposal and pollution owes. Of the 10% dry matter content of such waste, about 96% is organic and 4% is inorganic. Being rich in cellulose and hemicellulose, it can be a valuable resource for numerous value-added products by bioconverting it to valuable products, including bioenergy. Biomethane is one such energy resource that can be produced by valorizing pineapple wastes by employing various bioconversion technologies. This chapter focuses on the bioconverstion technologies to produce biomethane from pineapple wastes.

The following tests are used for microscopic evaluation of semen: 
    
12.1    Sperm motility
12.2     Per cent Live sperm
12.3     Sperm concentration

12.1 Sperm Motility

The following two methods of estimation of sperm motility are followed in routine practice:
 
12.1.1    Mass activity
12.1.2    Progressive sperm motility
12.1.1 Mass Activity

Mass activity can be defined as ‘en-mass activity of the spermatozoa in the semen, immediately after collection’. Mass activity is generally assessed by vigour of swirls and waves motion in undiluted semen under 20 X magnification and expressed on 0 to 5 scale.

Artificial insemination (AI) is the technique of placing sperm into a female’s uterus (intrauterine), or cervix (intracervical) using artificial means rather than by natural copulation. Modern techniques for artificial insemination were first developed for the dairy cattle industry to allow many cows to be impregnated with the sperm of a bull with traits for improved milk production. It is the first generation reproductive biotechnology which has revolutionized the animal productivity. It has now been established as cheapest and fasted mode of genetic improvement of livestock. AI can be done using fresh semen, semen preserved at room temperature, refrigerated (4ºC) and cryopreserved (-196ºC) semen. The use of AI with frozen semen has become very popular and is being successfully used throughout the country.

Introduction

India is an agriculture based country with 60% of the manpower employed in agriculture (World Bank, 2010). Few of the main environmental issues are soil erosion, water pollution from raw sewage and runoff of agricultural pesticides. There is a need to maintain a sustainable environment and a sustainable agricultural system.  Sustainable Agricultural system is a self sustaining system, is dependent up the ability to bring together and manage simultaneously the soil, water, plant and animal resources with the limitation of climatic and environment in such a way that the agricultural production/profitability can be maintained in the future too. So initiatives need to be taken to achieve a sustainable agricultural system. Tools have been developed to aid agriculturist, extension personnel and policy makers. The World Wide Web has made the tools easy accessible.

Introduction

Spatial planning tools brings together multiple users of the earth to make informed and coordinated decisions about how to use of resources  and helps to organize, analyze and present information from a number of different sources.  Thus, viewing from single interest or multiple use viewpoints is enhanced and can make a very important contribution to environment. Use of Remote Sensing (RS) and Geographical Information Systems (GIS) tools has the capacity to bring together experts from a variety of disciplines to address complex spatial problems.

Abstract

Accurate forecasting of the rice yields is very important for the organization to make a better planning and decision making. The aim of the study is to investigate the ability of neural network for yield prediction of rice in Andaman and Nicobar Islands. Field experiments were conducted at the various regions of Andaman and Nicobar Islands during 1980 to 2002 and data collected was subjected to Artificial Neural Networks (ANN) approach for developing a meaningful yield prediction for four varieties of rice C14-8, Quing Livan No.1, Taichung , Sen Yu, Jaya under island conditions with the objective to estimate the crop production a few days or months before harvesting of crop. The observations of all experiments viz., Varietal spectrum, Weather parameters , Yield components, Soil, Abiotic stressors, Biotic stressors for the period of twenty years from 1980 to 2002 were collected from the basic records of experimental field. All the data were used for training data set. Prediction of crop yield, mainly strategic plant of rice has been an interesting research area to agronomists since long for its importance in national and international economic programming. Application of ANN was found to be significant tool for prediction of yield in rice.

A DNA microarray is a multiplex technology used in molecular biology. It consists of an arrayed series of thousands of microscopic spots of DNA oligonucleotides, called features, each containing picomoles (10-12 moles) of a specific DNA sequence, known as probes (or reporters).

Data mining is becoming an increasingly important tool to transform the data into information. In recent years, data mining has been widely used in area of Bioinformatics for better understanding of gene expression, drug design, and other emerging problems in genomics and proteomics. Data mining is used to understand gene expression analysis, searching and understanding of protein mass spectroscopy data, 3D structural and functional analysis and mining of DNA and protein sequences for structural and functional motifs. For the first several hundred years of research in biology, the main bottleneck to scientific progress was data collection. Our new found data-richness, however, has shifted this bottleneck from collection to analysis. Biomedical literatures have been increased at the exponential rate. To find the useful and needed information from such a huge data set is a daunting task for users. Text mining is a powerful tool to solve this problem and it is used for biological knowledge discovery.

The choice of hormones and drugs acting on reproductive system are important as therapeutic agents during reproductive disorders like anoestrus, metritis, pyometra, repeat breeder, retention of fetal membranes, delayed puberty, ovarian disorders etc.  The administration of specific chemotherapeutic agent is of paramount importance in treating reproductive disorders in dairy animals.  The dosage, route, frequency and indications of chemotherapeutic agents acting on reproductive system are mentioned in tabular form as below.

Introduction

After the advent of Post Genomic era, Biological data is accumulating at an electrifying pace every day. Storage and analysis of these data serve as a major source for scientific research to understand the phenomena of origin, evolution and existence of various forms of life. The management of these data requires different statistical techniques used for retrieval, storage, analysis and extraction of precise information from small as well as large biological datasets. Application of statistical tools in Bioinformatics especially in fisheries data has been reported (Roy and Martha, 2008).
