Assay of Carotene, Tocopherol and Plant Pigments (Method of Astrup et al., 1971). Agricultural University of NORWAY, ÅS-NLH, NORWAY

Introduction

A method which assays the carotene together with chlorophyll a and b and xanthophyll was given by worker (1957, 1958) and this was a successful approach towards a useful routine procedure. Worker’s way of extraction is based on the use of aqueous acetone a technique which was studied by Davidson (1954). The separation is accomplished on an alumina column. Worker (1958) has used a double successive chromatography, once on magnesia and again on alumina, to obtain its separation from the other lipid components. The method developed by Astrup et al. (1971) permits simultaneous assay of tocopherol, carotene and plant pigments using alumina column.

Extension

Extension is that type of education which is stretched out to people in rural areas far and near, beyond the limits of education institutions to which the formal type of education is usually confined.

Education

Education is a process of bringing about desirable changes in the behaviour of human being.

Formal education: The hierarchically structured, chronologically graded ‘education system’, running from primary school through the university and including, in addition to general academic studies, a variety of specialised programmes and institutions for full-time technical and professional training.

Informal education: The truly lifelong process whereby every individual acquires attitudes, values, skills and knowledge from daily experience and the educative influences and resources in his or her environment - from family and neighbours, from work and play, from the market place, the library and the mass media.

Non-formal education: Any organised educational activity outside the established formal system - whether operating separately or as an important feature of some broader activity - that is intended to serve identifiable learning clientele and learning objectives.

Introduction

Although both maps and aerial photos present a “bird’s-eye” view of the earth, aerial photographs are NOT maps. Maps are orthogonal representations of the earth’s surface, meaning that they are directionally and geometrically accurate (at least within the limitations imposed by projecting a 3-dimensional object onto 2 dimensions). Aerial photos, on the other hand, display a high degree of radial distortion. That is, the topography is distorted, and until corrections are made for the distortion, measurements made from a photograph are not accurate. Nevertheless, aerial photographs are a powerful tool for studying the earth’s environment. 

Because most GISs can correct for radial distortion, aerial photographs are an excellent data source for many types of projects, especially those that require spatial data from the same location at periodic intervals over a length of time. Typical applications include land use surveys and habitat analysis. 

This unit discusses benefits of aerial photography, applications, the different types of photography, and the integration of aerial photographs into GISs.

SUMMARY

Sustainable agricultural development can only be possible, when all agricultural inputs used judicially. Soil management practices, like nutrient management, time schedule of fertilizer application, irrigation management etc. are should be manage in such away that resulted in best remuneration and sustain overall soil health. More over that, soil physical properties like, tilth, aeration and drainage are also play important role in soil productivity, so tillage operation should be carry out at proper  level of soil moisture condition to maintain good soil tilth which result in better soil environment for high crop yield. The most important factor in sustainable soil management for agricultural development is nutrient management and it's only possible through integration. So nutrient management through integrated approaches, like use of chemical fertilizer is decreases by integrating with organic manures, biofertilizer, green manure, neem cake, caster cake etc which resulted in sustainable crop production and good soil health on long-term basis.

Rice (2n = 24) is an annual grass (family: Graminae) with terminal panicles bearing the grains. It originated in Asia between the fourth and fifth millennia B.C. A substantial portion of the people in south and Southeast Asia and the southern part of China are depending on rice as staple food (Chang, 1976). Rice is planted in the most diverse environmental conditions of any major food crop, from sea level to around 3000 m altitude and from 30°S to 49°N. Temperature and day lengths are therefore quite diverse in the rice growing areas. Rice is also grown under water regimes ranging from dry land to deepwater fields where water may reach 5 m depth. The wide geographical distribution of rice and its early history of cultivation have resulted in the development of a great diversity of varietal types (Vergara, 1985).

Rice has been used as food by man for over 10,000 years and has fed a great number of people for a longer period than has any other crop. “Rice is life” for almost four billion people of the world contributing over 20 per cent of the total caloric intake of human population (Chaudhary and Tran, 2001). Rice is cultivated in 113 countries and on all continents except Antarctica and it is the staple food for 17 countries in Asia and the pacific, eight countries in Africa, seven countries, in Latin America and the Caribbean and one in the near east (IRC, 2003).

Globally rice is grown in around 155 million ha occupying one tenth of arable land, with an annual production of 579 million tonnes of rough rice (Iiyas Ahmed, 2003). The average productivity of 3.89 t ha^-1 of rice provides a per capita. Consumption of 100 to 240 kg per year across the globe. Over 90 per cent of the world’s rice is produced and consumed in Asia and more than half of it from India and China exploiting maximum arable land. More than two billion people obtain their 80 per cent calorie from rice and its derived products from 90 per cent of world’s rice area (FAO, 1999). Rice based on production systems and their associated post harvest operations employ nearly a billion people in rural areas in developing countries (IRC, 2003).

Stability and adaptability studies have been carried out for upland or hill rice varieties also. Amirthadevarathinam (1987) observed significant genotype × environment and reported that both linear and non-linear components were equally important for assessing stability of yield and four yield components in four environments. Both TKM 6 and Poongar were high yielding with adaptability and stability in addition to being especially suitable for unfavourable environments. Kuruvaikalangium was the best performer for all characters except grains per panicle for which PM 1023 was the best.

Dineshkumar (1987) evaluated sixteen early maturing genotypes for their stability in four major agroclimatic zones of the Karnataka state. No genotype was found stable as they observed more of unpredictable variance (pooled deviation) than predictable (genotype × environment linear).

Ganesh and Soundarapandian (1987) observed that stability of number of ear bearing tillers was a major contributor for yield stability Shivaprakash (1987) reported similar results.

Studies by Sinha and Biswas (1987) on yield and yield components of twenty photo insensitive rice cultivars revealed IR-36 and IET-4094 as high yielder with unit ‘bi’ and least ‘S² d_i’ and hence they were recommended to be suitable for general cultivation for all the environments under study. Similarly IET-2881, which had high mean yield with high ‘bi’ was found suitable for high yielding environments.

INTRODUCTION

Various procedures which are used for genetic improvement of crop plants are known as breeding methods. The breeding approaches that are more commonly used for genetic improvement of crop plants are called conventional breeding methods. Following conventional breeding methods were followed in improvement of crops.

Cattleya belongs to the family Orchidaceae. It is highly important in floriculture and has been cultivated since the 19^th century. The name “Cattleya” was given in the honour of “Sir William Cattley”. Cattleyas have earned the reputation as the “Queen of Orchids” and are known to the public as the ultimate in floral corsages. While no longer the reigning queen of the orchid floral industry it is difficult not to be impressed by a well-flowered Cattleya. No longer limited to white and various shades of lavender and purple, high quality flowers occur in all colours except true blue and black and in a wide range of plant sizes. They are widely known for their large, showy flowers and were used extensively in hybridization for the cut-flower trade until the 1980s when pot plants became more popular.

ORIGIN AND DISTRIBUTION

The genus was named in 1824 by John Lindley after Sir William Cattley who received and was the first to bloom a specimen of Cattleya labiata. William Swainson had discovered the new plant in Pernambuco, Brazil, in 1817 and shipped to the Glasgow Botanic Gardens for identification. After the first importation from Mr. Swainson, no more plants similar to the original Cattleya labiata were discovered for many decades, although many varieties of this species were found. Each variety differed in some way from the plant of Mr. Cattley, either in colour, blooming season or some similar horticultural aspect. Brazil is the centre of distribution, where more than half the species are found (Pabst and Dungs, 1975 and Cruz et al., 2003). They are found naturally only in the western hemisphere, occurring along with Laelias in three major regions of Tropical America i.e. Mexico and Guatemala, northern part of South America from the western Cordilleras of Colombia to British Guiana and the maritime provinces of southern Brazil. Within these three large regions are found most of the species of Cattleya except for C. dowiana in Costa Rica and C. skinneri var. autumnalis from Panama. The plants occur at considerable elevation where the mean temperature is much lower than the mean temperature for the latitude at sea level.

INTRODUCTION

Heterosis has contributed significantly towards increased crop production and it has become the basis of multibillion dollar agro-businesses in the world (Phillips, 1999). Hybridization is the important way that can create genetic variability and make new options. The F₁ population is obtained from the crossing of two homozygous but genetically dissimilar gametes or individuals (purelines in self pollinated crops or inbred lines in cross pollinated crops) that shows increased or decreased vigour over the better or mid parent value. Heterosis is maximum in F₁, generation which diminishes gradually in later generations. Hence, production of F₁, hybrid seeds of different flower crops is considered as the extreme focused area in floriculture industry.

Production of F₁ hybrids in ornamental crops was carried out even before Shull’s classical theory of hybrid vigour which was reported in 1971 for the first time in plant breeding. Benary Seed Company in Germany released F₁ hybrid in begonia (Begonia semperflorens) in the name of Prima Donna in 1909 (Reimann-Philip, 1983). But that time it did not attract the attention of plant breeders. It was during Second World War in 1942, when flower breeders were attracted towards heterosis breeding and started systematic F₁ hybrids. From 1950 onwards, numerous outstanding hybrids have been developed in many other flower crops in several countries like USA, The Netherlands, Denmark, Germany, United Kingdom and Japan, etc. First hybrid in single geranium was produced in 1960, in other flower crops like antirrhinum, pansy, marigold and zinnia in 1965, ageratum in 1966, geranium double in 1970, dianthus, begonia, impatiens and portulaca in 1976-77, gerbera in 1980 and carnation in 1981. In the present scenario of developed floriculture industry, in many countries F₁, hybrids are available in a number of annual flowers like ageratum, antirrhinum, anemones, calceolaria, dianthus, hollyhock, gazania, marigold, flowering tobacco, pansy, portulaca, stock, wall flower, zinnia, etc.

As emasculation is having the maximum share in cost of hybrid seed production, researchers have found several techniques in different flower crops as the alternative of emasculation and that can help in reducing the cost of hybrid seed production. The list of techniques being utilized commercially in different flower crops (Janakiram, 2004) is as follows:

INTRODUCTION

The seed (or zygotic seed) is the vehicle that connects one generation to another in much of the plant kingdom. By means of seed, plants are able to transmit their genetic constitution in generations and therefore seeds are the most appropriate means of propagation, storage and dispersal. A synthetic seed or ‘synseed’ is “an encapsulated single somatic embryo”, i.e., a clonal product that can be handled and used as real seed for transport, storage and sowing and that, therefore, would eventually grow either in vitro or ex vitro, into a plantlet through a process of “conversion”. Now a day, artificial seed technology is one of the most important tools to breeders and scientists of plant tissue culture.

In general, synthetic seeds are defined as artificially encapsulated somatic embryos, shoot tips, axillary buds or any other meristematic tissue, used for sowing as a seeds and posses the ability to convert into whole plant under in vitro and in vivo conditions and keep its potential also after storage (Capuano et al., 1998). The aim and scope for switching towards artificial seed technology was for the fact that the cost-effective mass propagation of elite plant genotypes will be promoted. There would also be a channel for new transgenic plants produced through biotechnological techniques to be transferred directly to the greenhouse or field. The artificial seed technology has been applied to a number of plant species belonging to angiosperms.

Artificial seeds have great potential for large scale production of plants at low cost as an alternative to true seeds (Roy and Mandal, 2008). An artificial seed is often described as a novel analogue to true seed consisting of a somatic embryo surrounded by an artificial coat which is atmost equivalent to an immature zygotic embryo, possibly at post-heart stage or early cotyledonary stage. The artificial seed production technique was first used in clonal propagation to cultivate somatic embryos placed into an artificial endosperm and constrained by an artificial seed coat. Today artificial seeds represent capsules with a gel envelope, which contain not only somatic embryos but also axillary and apical buds or stem and root segments (Vdovitchenko et al., 2011). Explants such as shoot tips, axillary buds and somatic embryos are encapsulated in cryoprotectant material like hydrogel, alginate gel, ethylene glycol, dimethylsulfoxide (DMSO) and others that can be developed into a plant. The coating protects the explants from mechanical damage during handling and allows germination and conversion to occur without inducing undesirable variations. They behave like true seeds and sprout into seedlings under suitable conditions.

Hibiscus a well known member of the family Malvaceae, grows as an evergreen shrub plant. The plant is extensively cultivated as an ornamental plant that bears large flowers on the bushy hedges. These enormous flowers are usually dark red in colour and are not usually fragrant. The huge size and the reddish colour and hues attract humming birds (Kumar and Singh, 2012). The generic name is derived from the Greek word “hibiskos” which was the name Pedanius Dioscorides gave to Althaea officinalis. Hibiscus rosa-sinensis was named by Carolus Linnaeus. The Latin term “rosa-sinensis” literally means “rose of China”, though it is not closely related to the true roses. Member species are often noted for their showy flowers and are commonly known simply as hibiscus, or less widely known as rose mallow. The hibiscus is used as an offering to goddess Kali and Lord Ganesha in Hindu worship. Hibiscus is an important flowering and garden plant. It has various medicinal values (Chopra et al., 1996 and Sayed et al., 2012).

ORIGIN AND DISTRIBUTION

The ancestors of the modern exotic hibiscus were originally native to Mauritius, Madagascar, Fiji, Hawaii, China and India. Ornamentally most important species is Hibiscus rosa-sinensis. There is no known record of the history of the domestication of Hibiscus rosa-sinensis. In one view it is believed that the species is a native to China and was first cultivated by the Chinese for its showy flowers (Kimbrough, 1997). No extant wild populations of the species have however, been reported from that country. Another view holds that the species is a native of the South Indian Ocean islands of which Madagascar, the Mascarene Islands and the Rodriguez Islands are a part (Borssum Waalkes, 1966). This view is strengthened by the fact that three Hibiscus species genetically compatible with H. rosa-sinensis are native to this area (Singh and Khoshoo, 1989). It is thought that the species was collected and domesticated on these islands by far easterner during their westward migration.

Impatiens balsamina (Balsam, Garden Balsam or Rose Balsam or Gulmehndi) is a species of Impatiens widely cultivated as an ornamental plant in landscaping belongs to the family Balsaminaceae. It is a qualitative short-day plant, propagated by seed and is one of the popular species of North India. It is called kamantigue in the Philippines. This species of Kamantigue are used in teas. In many English speaking countries they are known as “Touch me not”, possibly due to the ripe seed pods explosively bursting when touched. Different parts of the plant are used to treat disease and skin afflictions such as the leaves, seeds, and stems. It is also edible if cooked. Juice from balsam leaves treats warts and also snakebite, while the flower can be applied to burns to cool the skin. Impatiens balsamina L. has been used as indigenous medicine in Asia for the treatment of rheumatism, fractures, and fingernail inflammation. In Korean folk medicine Impatiens (‘Bong Seon Wha Dae’) has been used to cure constipation and acute gastritis by meat. There are mainly four forms of I. balsamina namely red, purples, white and pink.

ORIGIN AND DISTRIBUTION

Impatiens balsamina is a species of Impatiens native to southern Asia in India and Burma, but has been cultivated widely. It is now naturalized in many tropical and temperate areas of the world. Jones and Smith in 1966 proposed the Himalayan region as the centre of origin. The major centres of diversity are in highlands and mountains of tropical and sub-tropical Africa, Southeast Asia and the Indian sub-continent. In the U.S., Impatiens balsamina is found primarily in a wide strip encompassing the Northeast and Southeast regions from Florida to New York with specimens being found as far west as Missouri. Impatiens denisonii is a scapigerous herb which is found only in the Western Ghats in South India and are endemic in the Nilgiri Hills. Impatiens ecornuta, the spurless touch-me-not or western touch-me-not, is an annual flowering plant native to the northwestern United States and British Columbia in Canada. Impatiens flaccida is native to the Western Ghats in India and to Sri Lanka whereas, Impatiens hawkeri (New Guinea impatiens) is native to Papua New Guinea and the Solomon Islands. It has been bred and hybridized in cultivation to produce a line of garden plants. The species has been crossed with Impatiens aurantiaca and I. platypetala to improve characteristics such as drought-resistance. Impatiens irvingii is native to tropical Africa. Impatiens namchabarwensis (Blue Diamond Impatiens) is a 40–50 cm tall perennial plant, native to the Himalaya overwintering by a thick fleshy rootstock. Impatiens psittacina, known variously as the “parrot flower” or “parrot balsam” is a species of balsam from Southeast Asia that was described by the botanist Joseph Dalton Hooker and was noted for its flower that resemble a “flying cockatoo”. It is known from Thailand, Burma and parts of India (Morgan, 2007). Impatiens sodenii is native to Kenya and Tanzania. It is widely cultivated as an ornamental plant. I. walleriana is native to East Africa and yielded ‘Elfin’ series of cultivars, which was subsequently improved as the Super Elfin series.

Dahlia (Dahlia spp.) syn. Georgina belongs to family Compositae (Asteraceae). Dahlia was named after “Professor Andreas Dahl”, a Swedish pupil of Linnaeus and author of Observations Botanicae. In India, dahlia is grown as potted plant and landscape uses but it is a poor crop as commercial flower due to shorter commercial life and its potentialities have not been exploited so far. Therefore, there is need to originate more and more new quality cultivars. Dahlias are half-hardy perennials with tuberous roots. Stems are mostly erect, branched, glabrous or scabrous. The leaves 1-3 pinnate, with slightly serrated margin are produced opposite at each node on the stem. They bear flowers on a long, stiff stems well above the foliage. Ray florets are neutral or pinnate and disc florets perfect.

ORIGIN AND DISTRIBUTION

The wild species of Dahlia are natives of Mexico and Central America, where some hybridization and selection had probably already occurred prior to their introduction into Europe at the end of the 18^th century (Crane et al., 1947 and Sorensen, 1969). The dahlia has been in Europe for over 200 years. It came from Mexico to the Botanical Gardens in Madrid towards the end of the 18^th century and was named by Abbe Cavanille in honour of Andreas Dahl, Swedish scientist-cum-environmentalist. The dahlia was introduced into England in 1803, but from a few varieties it soon had more than 300 varieties within the first 15 years. The initial named species imported into Europe were D. pinnata, D. rosea and D. coccinea. The first dahlias grown outside of Madrid were single (open-centred) and multi-ray open centre flowered, but it was not long before the horticultural growers of the day discovered the dahlia was a natural hybrid and when grown from seed, it readily changed its form and colour, Thus it has a range of different types. Further introduction, accompanied by hybridization and selection, have resulted in the production of a wide range of flower, forms and colours. Most of the garden types have been developed from D. variabilis. The first double flowered varieties were called Show and Fancy types. The show were self-coloured, ball like flowers, while the Fancy ones were multi-coloured.

During the mid 1800’s, these Show and Fancy flowers attained cult status with gardeners and several thousand different varieties were recorded. Other forms followed, in 1829 the first Anemone flowered dahlia appeared and then in 1850 the first Pompon was raised in Germany and was named after the bobble on a French sailor’s hat. The origin of the cactus and Decorative type belongs to the arrival of ‘Juarrezii’. According to the written records it was important as a piece of tuber from Mexico in 1872 to Holland. M. Van de Berg of Uttrecht received this so called species from Mexico and released stock of the variety in 1874. Subsequently, ‘Juarrezii’, named after a President of Mexico, was introduced into the UK by W. Cullingford a Vice President of the NDS and distributed by H. Cannell after 1880. Collerettes are the last form of dahlia to have been raised, that has their origin in France and is due to sporting of dahlias at Jardin Botanique de Lyon at the end of the 19^th century.

1. Introduction

The development of food products using composite flour has increased and is attracting much attention from researchers, especially in the production of bakery products and pastries. This article focuses on the use of composite flour to produce food products, namely bread, biscuits, and pasta, with looks at on its impact, following some improvements made, on the sensory quality, rheology characteristics, and nutritional values as well as its overall acceptance. The blending of wheat flour with various sources of tubers, legumes, cereals and fruit flour in different percentages to produce variety of food products are also reported. The positive effects of the use of composite flour can be seen in the final product related to the functional and physicochemical properties and health benefits of raw blended flour along with percentage blending. Overall, composite flour is a good new approach to utilizing uncommon food products as the application of composite flour produced products with different characteristics and quality, depending on the types and percentage of wheat flour used in the formulation.

Bread has been the staple food worldwide and habit of bread is derived in part due to the convenience and wholesomeness. Wheat is a commonly used cereal for making bread as it gives the desired texture due to the presence of gluten forming proteins like gliadins and glutenins (Decock & Cappelle, 2005). In earlier times idea of composite flour in developing countries originated in order to cut down on import of wheat (as it was not grown in many countries) but in recent past refined wheat flour consumption has lead to health issues and thus in order to improve nutritional and functional properties composite flour has been the norm. Composite flour is the one obtained by mixing wheat flour with cereal and legume flours for making bread and biscuits (Dendy, 1992). However, mixing of non-wheat flours, roots and tubers, legumes or other raw materials can also be regarded as composite flour.

1. Introduction

Now a days, foods are not intended to only satisfy hunger and to provide necessary nutrients but also to prevent nutrition-related diseases and improve physical and mental well-being of the consumers (Menrad, 2003). In this regard, functional foods play an important role. The concept of functional foods which has evolved as the role of food in the maintenance of health and well-being and in the prevention of disease, has received increased scientific and commercial interest is recent past. Growth of functional foods markets include increased consumer health awareness, increased popularity of healthy foods, search for food-based drug substitutes, self-medication approach promoted by busy lifestyles and rapidly developing health conscious markets. Functional foods can be defined as foods “that can beneficially affect one or more target functions in the body, beyond adequate nutritional effect, in a way relevant to an improved state of health and wellbeing and/or reduction of risk of disease” (Stanton et al., 2005).

1. Introduction

A confection is sweet tasting delicacies developed using sugar and other carbohydrates with optionally selected chocolate, nuts, fruits, vegetables or gums. Depending on the formulation, the confection may vary from sugar boiled hard lozenges to gum based soft gummy toffees, from chewing gums to mouth melting chocolates. The versatile and broad variation in the product created by differentiating flavours, ingredients and processing has greatly influenced the market demand of these products. Although confection is non-essential commodity but still relished by people of all economic strata and hence creating a great market space and scope of new products.

In confectionery research and development area, current popular sector is functional confections. The sector has been on the trends radar globally, accounting for 8% of the global confectionery market, and most accepted and successful in Japan.

Avian influenza (AI) is a listed disease of the World Organization for Animal Health (OIE) that has become a disease of great concern for both animal and human health. Avian influenza (AI) or 'bird flu' is an infectious disease of birds ranging from a mild to a severe form of illness. It is caused by influenza A virus under the family Orthomyxoviridae. It is an enveloped virus with two types of surface projections haemagglutinin (H) and neuraminidase (N). The haemagglutinin is a rod shaped homotrimer which agglutinates RBCs and neuraminidase is a mushroom shaped homotetramer which releases the virus from cells because of its sialidase activity. There are 17 different H antigens (H1 to H17) and 10 neuraminidase antigens (N1 to N10). The virus also contains 8 single stranded negative sense RNA segments each of which encodes for a protein. Avian influenza virus is generally limited to poultry but an unprecedented epizootic of avian influenza A (H5N1) that is highly pathogenic has crossed the species barrier in Asia to cause many human fatalities and likely to possess an increasing pandemic threat. Zoonotic potential of AI virus was first recorded in 1997 with hospitalization of 18 people (six died) following the infection with HPAI (H5N1) in Hong Kong. This provided the evidence that HPAI strains of chicken can adapt, multiply and even cause death in affected individuals. So, it is the prime time to create awareness about the HPAI and its transmission to human beings so that necessary precautionary measures can be taken to prevent and control the disease efficiently and effectively.

Etiology: Influenza viruses are under the Orthomyxoviridae family and belong to either influenza A or influenza B or influenza C genus. The virus particles are enveloped with glycoprotein projections having haemagglutinin or neuraminidase activity and contain 8 negative sense single stranded RNA. Influenza A viruses are classified into subtypes based on these two surface antigens, haemagglutinin (H) and neuraminidase (N ). The haemagglutinin is a rod shaped trimer which agglutinates RBCs and neuraminidase is a mushroom shaped tetramer which releases the virus from cells because of its sialidase activity. Beneath the lipid envelope there is a membrane or matrix (M) protein which surrounds a helical complex containing the nucleoprotein (NP) and polymerases (PB1, PB2, P) protein. There are also two nonstructural protein (NS) present in the virus. There are 17 haemagglutinin antigen (H1 to H17) and 10 neuraminidase antigens (N1 to N10) present in influenza A viruses. Each RNA strand of AI virus code for at least one protein. The H glycoprotein of influenza virus has two important functions which are imperative for the infectivity of the virus (i) it is responsible for attachment of the virus to the host cell receptors of glycoprotein or gangliosides containing sialic acid. (ii) it possesses fusion activity between the host cell membrane and the virus membrane so that virus genetic material is introduced into the host cell. The glycoprotein is produced as a precursor, HAo which requires post translational cleavage to HA1 and HA2, by host proteases before it is able to induce membrane fusion. Then only the B virus particles becomes infectious. Type A viruses include the avian, swine, equine and human influenza A viruses. The large number of subtypes present in the type A influenza viruses are due to fact that viruses often undergo antigenic shift by the process of genetic reassortment.

Dengue is a mosquito-borne viral disease and considered to be a major health problem globally. It is also called break-bone fever, dandy fever, denguero bouquet fever, giraffe fever, Polka fever and 5 days or 7 days fever. There are two important manifestations, namely dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS) which are responsible for heavy morbidity and mortality every year causing serious concern to health. It is an important disease caused by an arbovirus worldwide especially in the tropical and subtropical regions. The severity of the disease can be judged from simple statistics that over 40 per cent (2.5 billion) of the world's population in 100 countries continue to live under threat of contracting dengue infection. Annually, dengue virus infections are responsible for up to 100 million cases of dengue fever and more than 500,000 cases of haemorrhagic fever. Besides, every year the disease forces nearly 500,000 people to hospitalization of which 90% are children and causing 24,000 deaths. Mostly these deaths are due to lack of early diagnosis of dengue virus infection. In DHF case fatality rate generally exceeds 20 per cent in a non-endemic population and it can be reduced to less than 1 per cent with the aid of modern supportive therapy based on early diagnosis of the type of viral infection.

Dengue fever (DF) is an acute febrile viral disease characterized by headaches, bone or joint and muscular pains, rash and leucopenia as symptoms. Dengue haemorrhagic fever (DHF) is characterized by four major clinical manifestations: high fever, haemorrhagic phenomena, 73 often with hepatomegaly and in severe cases, signs of circulatory failure. Such patients may develop hypovolaemic shock resulting from plasma leakage. This is called dengue shock syndrome (DSS) and can be fatal.

The year 2001 witnessed unprecedented global dengue epidemic activity in the American hemisphere, the Pacific Islands and continental Asia. During 2002, more than 30 Latin American countries reported over 1 million DF cases with large number of DHF cases. This has been followed by extensive epidemics of DHF in several parts of India during 2003.

Dengue fever (DF) is caused by ingestion of viraemic blood containing dengue virus by mosquitoes of Aedes sp. followed by passage to a second human host. An extrinsic incubation period is required before the virus appears in the saliva of the transmitting female Aedes mosquitoes. After the bite, there is an incubation period of 3 to 14 days (average 4 to 7 days) followed by the onset of fever and nonspecific signs and symptoms (frontal headache, retro-orbital pain, body aches, nausea and vomiting, joint pains, weakness and rash). The febrile phase is self limiting and may last for 2 to 10 days followed by remission of fever in most cases. Laboratory abnormalities include neutropenia followed by a lymphocytosis and thrombocytopenia.

Leptospirosis is a worldwide zoonosis. According to the occupational groups involved and the nature of the disease presentations, different names have been used, e.g. seven-day fever found commonly in Japan, Cane cutter's disease in Australia, Rice field Leptospirosis in Indonesia and Fort Bragg fever, which appeared as an outbreak in the US. Weil's disease, which is one of the severe forms of this disease, occurs in many countries, including India and other South-East Asian Countries, China, continental Europe and England. Leptospirosis exists in all the five inhabited continents and in a large number of countries. It occurs in tropical, subtropical and temperate zones. Leptospirosis is also an important cause of abortions, stillbirths and reproductive failures in cattle and pigs. Periodic ophthalmia in horse is commonly associated with leptospiral infections. Leptospirosis was first recognized in humans in 1886 by Weil and characterized by icterus. Leptospira have been isolated from a variety of animal species and humans manifesting various clinical syndromes such as mud fever and swine herd disease.

Etiology: The etiologic agent of leptospirosis is Leptospira interrogans. It is a thin spiral organism 0.1mm x 6 -20mm, with tightly set coils, and it is characterized by very active motility, by rotating ("spinning") and bending. Usually one or both ends of this single-cell organism are bent or hooked, but straight forms also occur that rotate and travel more slowly than hooked forms. The cells have pointed ends, either or both of which are usually bent into a distinctive hook. Two axial filaments (periplasmic flagella) with polar insertions are located in the periplasmic space. The structure of the flagellar proteins is complex. Leptospires exhibit two distinct forms of movement, translational and nontranslational. Morphologically, all leptospires are indistinguishable, but the morphology of individual isolates varies with subculture in vitro and can be restored by passage in hamsters. Leptospires have a typical double membrane structure in common with other spirochetes, in which the cytoplasmic membrane and peptidoglycan cell wall are closely associated and are overlain by an outer membrane. Leptospiral lipopolysaccharide has a composition similar to that of other Gram-negative bacteria, but has lower endotoxic activity. Leptospires may be stained using carbol fuchsin counterstain. Leptospires are obligate aerobes with an optimum growth temperature of 28 to 30°C. They produce both catalase and oxidase. They grow in simple media enriched with vitamins (vitamins B₂ and B₁₂ are growth factors), long-chain fatty acids, and ammonium salts. Long-chain fatty acids are utilized as the sole carbon source and are metabolized by b-oxidation. Because of their narrow diameter, the leptospires are best visualized by dark-field illumination or phase contrast microscopy and they do not stain readily with aniline dyes. The free living (L. biflexa) and parasitic leptospires (L. interrogans) are morphologically indistinguishable.

Importance of Traditional Foods

Traditional convenience food, or tertiary processed food, is commercially prepared food designed for ease of consumption. Products designated as convenience foods are often prepared food stuffs that can be sold as hot, ready-to-eat dishes; as room-temperature, shelf-stable products; or as refrigerated or frozen products that require minimal preparation (typically just heating).

These products are often sold in portion controlled, single serve packaging designed for portability for “on-the-go” eating. Convenience food can include products such as candy; beverages such as soft drinks, juices and milk; fast food; nuts, fruits and vegetables in fresh or preserved states; processed meats and cheeses; and canned products such as soups and pasta dishes.

Traditional Foods

Preparation of Vadagam and Appalam

Vadagam is a traditional product mostly prepared from rice flour and also sago. It is an deep fat fried product and consumed as a side dish in the meals. Papad also known as appalam or papadam in South India, is essentially a thin wafer like product, usually circular in shape rolled from a dough made out of pulse, cereals, edible vegetable oil, alkaline and mucilaginous additives. It is normally consumed in toasted or fried form. In India, papad has been associated and deeply entwined with social customs/ rituals and has been developed into culinary art.

Carbon is found in all living organisms and is the major building block for life on earth. It exists in many forms, predominantly as plant biomass, soil organic matter, and as the gas CO₂ in the atmosphere and dissolved in sea water. Carbon cycles globally among five distinct pools among which the largest oceanic poolis estimated at 38000 Pg (Pg= petagram =1x10¹⁵g=billion tonnes) and is increasingat the rate of 2.3 Pg C yr^-1 (Fig. 1). The geological C pool, comprising fossil fuels, is estimated at 4130 Pg, pedologic, estimated at 2500 Pg to 1m depth, atmospheric pool comprising 760 Pg of C with nearly all of it as CO₂, and the smallest among theglobal C pools is the biotic pool estimated at 560 Pg. The pedologic and biotic C pools together are called the terrestrial C pool estimated at approximately 2860 Pg.

1. Introduction

Jackfruit (Artocarpus heterophyllus) is one of the most significant trees in tropical and subtropical homegardens and perhaps the most widespread and useful tree in the important genus Artocarpus. Jackfruit belongs to the family Moraceae. The word “jackfruit” comes from Portuguese jaca, which is derived from the Malayalam language term, Chakka. Jack fruit native to India and seen abundant in Western Ghats (Wangchu et al.,2013). Besides India, jackfruit is commonly grown in home gardens of tropical and sub-tropical countries especially Sri Lanka; Bangladesh, Burma, Philippines, Indonesia, Thailand, Malaysia and Brazil. In India, it widely distributed in the states of Assam, West Bengal, Uttar Pradesh, Maharashtra, Kerala, Tamil Nadu and Karnataka and considered to be the “Poor mans food” (Prakash et al., 2009). In Malayalam, jack fruit is called as “Chakka” while the ancient Indian language Sanskrit refers as Atibruhatphala (Baliga et al., 2011). The morphology of the tree varies with 10-30 m tall; with long tap root and dense crown producing the largest tree born fruit in the world. The fruit weight up to 50 kg, but average weigh is considered to be 10 kg, while only 30-35% of the bulb is edible. Jack fruit is considered as national fruit in Bangladesh and highly appreciated in India due to cheap and availability in summer seasons were food is scarce (Muralidharan et al., 1997). It is a monoecious tree and both male and female inflorescences are found on the same tree. The fertilization is by cross-pollination and the propagation is mostly through seeds. The complete fruit development process takes about three to seven months from the pollination, varying in different countries. Jackfruit consists of lower fleshy edible region (bulb), middle fused region (syncarp) and out spiney region (spike). When ripe the fruit get fleshy, outer spines widened and flesh get soft and yellow. Except the thorny outer bark and axis are not edible (Baliga et al., 2011). The jackfruits were classified based on their phonotypical and organoleptic characteristics with variation in bulb colour as well as shape, size, odour, flake size, flake colour and period of maturity. Two types of ecotypes are recognized, one with soft and spongy flakes or bulbs while other with firm carpels.

Mango (Mangifera indica L.) is one of the choicest and most ancient fruits known to mankind. It occupies a pre-eminent place amongst the subtropical fruits grown in Jammu region and occupies an area of 12,739 ha with annual yield of 24,150 metric tons. It is extensively grown in Jammu district and also in the sub-tropical areas of Udhampur, Reasi, Kathua and Rajouri districts.

Climate and Soil

Mango thrives well up to 600 m above mean sea level provided locality is frost free and there is no high humidity or rains during flowering. The favourable temperature is 24⁰ C to 27⁰ C, however, it can tolerate temperature as high as 48⁰ C provided that trees are getting regular irrigation.

Mango has been found to grow on a wide range of soils. However, deep and well-drained sandy loam soils are most suitable for its cultivation. Heavy black cotton, saline and alkaline soils should be avoided. The ideal range of soil pH for mango cultivation is 5.5 to 7.5.

Apple (Malus x domestica Borkh.) is a premium fruit of the world. It is a typical temperate fruit and main fruit crop of J&K State. The area under this fruit in J&K State is 1,62,971 hectares with an annual production of 17,26,834 metric tones. The acreage under this fruit crop in Jammu Division is 18,146 hectares and the annual production is 38,421 metric tones. In Jammu Division, apple is being grown in upper areas of Doda, Kishtwar, Ramban, Poonch, Udhampur, Reasi, Kathua and Rajouri districts.

Climate and soil

Apple is a typical temperate fruit crop requiring 1000-1600 hours of rest period below 7^oC. The average temperature during growing season should be 21⁰C to 24⁰C. Sunshine is essential for colour development of the fruit. In general, a cool climate with low winter temperature and little rainfall in summer is most suitable for apple cultivation.

Apple is grown on a wide range of soils. However, a well drained slightly acidic (about 6.5 -6.7 pH) loam soil with good depth (more than 45 cm) is ideal for apple cultivation. Apple can’t tolerate wet field, and water logging may cause collar rot and death of trees.

Packaging means a coordinated system of preparation of goods for distribution, storage, merchandizing and shipment at optimum cost compatible with the requirements of the product. It also includes the art, science and technique used, preparatory to and during transportations and selling of goods and technical methods and work processes related to the above preparations.

The broad range of dairy products necessitates that packaging equipment and materials encompass nearly all types from flexible to rigid and from high to low barrier. The general types of packaging and equipment are discussed below with a focus on fluid products but it must be recognized that other dairy products such as cheese have their own particular packaging requirements and technologies.

Role of packaging in distribution and sale: The essence of what makes milk and dairy products important source of human nutrition also causes rapid deterioration and high perishability. The major role of dairy packaging is to retard the deterioration by preventing microbial recontamination and excessive chemical deterioration. Fluid products are especially susceptible to microbial, enzymatic and chemical degradation. In addition to retarding quality loss, packaging must provide containment, facilitate use, identify products, communicate, and appeal to consumers, all with maximum production efficiency. The large volumes and low unit value means that these functions must be met with minimal economic cost and environmental impact. Because food packaging is generally highly regulated, legal requirements must also be understood and met.

Resistance of some plants against a pathogen is due to their belonging to taxonomic groups which are outside the host range of the pathogen. Such resistance is called non host resistance. It is attributed either to genes for resistance (R genes) against the avirulence genes of the pathogen (true, race specific, cultivar-specific, or gene-for-gene type resistance), or to the plants escaping or tolerating pathogen infection due to various reasons (apparent resistance). There are two kinds of true resistance: partial (also called quantitative, polygenic, or horizontal resistance) and R gene resistance (also called race specific, monogenic, or vertical resistance). Several examples of true resistance attributable to, biochemical underpinning or genetic transformation of host plants of major fruit crops viz., apple, pear, apricot, plum, cherry, almond, mango, grapes, banana, citrus, papaya, guava and pomegranate against important plant pathogens are known. Much greater efforts need to be invested, however, for incorporating resistance to diseases in horticultural species because of their huge relevance to socio-economic well being of farming community of the hill regions. The effort in this chapter will be towards synthesizing information which officials of the administrative and development departments can use for drafting plans and policies for promoting protection and up gradation of livelihoods of hill farmers.

An efficient management of animals will be incomplete without a well planned and adequate housing of animals. Improper planning of animal housing leads to additional labor charges. The housing should have proper sanitation, durability, arrangements for the production of clean milk under convenient and economic conditions.

a) General Housing Requirements

Dairy animals will be more efficient in the production of milk and in reproduction if they are protected from extreme heat, and particularly from direct sunshine. This can be achieved through provision of shade in tropical and subtropical climates. If dairy animals are confined, the area should be free of mud and manure in order to reduce hoof infection to a minimum. Concrete floors or pavements are ideal where the area per animal is limited. However, where ample space is available, an earth yard, properly sloped for good drainage is adequate.

Introduction

The dairy farmers mostly keep cows (indigenous and crossbred) along with few buffaloes for milk production. However, the genetic potential of the dairy animals is exploited fully, when they are fed with well balanced ration. Further, as feed cost is around 75% of the total cost of production, the success of the dairy farming depends not only on the quality of the ration, but also on the economy of the ration. Therefore, knowledge on the feeds and feeding of dairy animals is highly essential.

What is Feed?

Feed may be defined as supplementation of nutrients for development, maintenance and operation of day to day activities by animals.

The basic aim of seed legislation and its subsequent enforcement is to regulate the quality of seeds sold to farmers. So long as Agriculture remains tradition and static, there is little justification for regulating seed quality. However with technological advancement and the systematic application of science to Agriculture, it becomes compulsory to regulate the quality of seeds through seed legislation and its subsequent enforcement to ensure that seed buyers are not made to run undue risks.

TYPES OF SEED LEGISLATION

Seed legislation can be broadly divided into two groups.

1.    Sanctioning legislation

2.    Control legislation

Sanctioning Legislation

Which authorizes, establishes or otherwise legally sanctions such activities as formation/establishment of advisory bodies, seed certification agencies, seed testing Labouratories, foundation and certified seed programmes, recognition of seed certification agencies of foreign countries, appellate authority etc.

Agricultural research has been primarily focused to assure food self-sufficiency and security, and little concern on nutritional value “nutritional security” or health promoting qualities of food being produced. Food security has three dimensions, namely: (1) endemic hunger caused by poverty-induced under-nutrition and malnutrition; (2) hidden hunger caused by the deficiency of micronutrients like iron, iodine, zinc and vitamin A in the diet; and (3) transient hunger caused by natural calamities or civilian conflicts. Micronutrient malnutrition is recognized as a massive and rapidly growing public health issue especially among poor people living on an unbalanced diet.
 
Although great progress has been made in reducing the prevalence of hunger, over 805 million people are undernourished in 2012-14, still unable to meet their daily calorie needs for living healthy lives. This number has fallen by 100 million over the last decade (Table: 1 & Table: 2; Source: FAO, 2014). Undernourishment refers to food intake that is insufficient to meet dietary energy requirements for an active and healthy life. About one in nine people go to bed daily on an empty stomach. In cases where food is available, often the quality of the food does not meet micronutrient (vitamin and mineral) needs. More than two billion people continue to suffer from nutritional deficiencies such as vitamin A, iron, zinc and iodine. Despite progress, the number is still high, and marked differences across regions persist. 

Solanaceous Vegetables

Solanaceous vegetables are also infested heavily by several major insect pests.

Brinjal Solanum melongena L.
 
Fruit and shoot borer Leucinodes orbonalis Gunnee (Lepidoptera: Pyraustidae)

Economic importance: Most destructive pest of brinjal, found throughout the country. Besides brinjal, the pest is also known to infest potato, bitter gourd, pea pods, cucurbits and other solanaceous etc. The infestation on brinjal can be as high as 70 per cent. The pest is active throughout the year, except in severe cold weather in North India.
 
Mark of identification and life cycle: Moths wings are white with pinkish or black tings and are ringed with small hair along the apical and anal margins. The fore wings are ornamented with a number of black, pale and light brown spots. Female lays 80-120 creamy white eggs, singly or in batches of 2-4 on the underside of leaves, on green stems, flower buds or the calyces of fruits. Caterpillars are creamy when young, but light pink when full-grown in 9-28 days. Pupate in tough silken cocoons among the fallen leaves with period of 6-17days and adult survive for 2-5days of its life cycle. A single life-cycle takes 22 - 25 days extending up to 74 days during winter and there may be 8 - 12 generations in a year.

1. Brief Basic Information on Country and Agrarian Status

Peru is the third largest country in South America with 1,285,215 square-meters and in general, there are three well defined regions: the Coast (11 per cent of the territory), the highlands (30 per cent of the territory) and the jungle (59 per cent of the territory). Peru is characterized by the high variability of agro-ecosystems ranging from Deserts in the Coast, lowlands, hills, high mountains, and rainforest in the Jungle. Each region has different agro-climatic conditions, infrastructure and enterprise development. The total cultivable land area is 54,76,977 hectares that is equivalent to 4.3 per cent of the national territory. The coast has 8,70,200 hectares of irrigated land (no rain-fed land because of lack of rain in the coast) and has the best conditions for cultivation of export crops. The highlands have 28,33,800 hectares of cultivable land, 70 per cent of them is under rain-fed condition and the total of the 17,73,000 hectares of cultivated land under rain-fed conditions1 . Land property has undergone a process of changes in the last 40 years.

ABSTRACT
The rapid industrialisation and speedy progress towards urbanisation across the world have created the huge demand for energy moreover creating enormous quantity of wastes. The latter is in charge for polluting the environment in an exponential manner, resulting out of the harmful and poisonous compounds released by them. In recent years, there has been a pattern change from ‘waste-to-wealth’, considering the value of high organic fraction accessible in the wastes. The best-accomplished methods are that of anaerobic digestion; contribute to the production of methane (CH₄). Similar biotransformation has partial net energy harvests. Recently, fermentation industries steering their interest towards the production of value added products, viz., biohydrogen (H₂), biopolymers, ethanol, vitamins, acetic acid, enzymes, butanediols, etc. from carbon rich organic waste like cellulosic substrates have been envisioned to flourish in a multi-step process, such as the ‘Biorefinery’. A contemporary development in fermentation technology holds the key to overcome the constraints for such processes that may lead to a sustainable economy. One related technology is electrofermentation that has attracted significant attention recently owing to its capacity to boost the metabolic activities of microbes by means of extracellular electron transfer.

Abstract
Proteins are comprised of domains, folds and motifs, which form its basic building blocks. Most efforts to understand protein evolution and its function have focused on domains as these can fold into a stable three-dimensional structure independent of the rest of the protein chain and generally perform a unique function conserved over the evolution. Genetic recombinant techniques allow reorganization of domains, called domain shuffling, resulting in different combinations of domains in different proteins. This along with swapping and insertion of domains results in complex architectures and are responsible for new protein functions in evolution. Protein domains are very useful in analyzing the mechanisms of protein folding and their stability and structural transformations in various conditions. This can be done reliably if a multi-domain target is considered only in terms of its constituent domains. The underlying goal is to reduce a complex protein structure to a set of simpler yet structurally meaningful units, each of which can be analyzed independently.

Modern research on life science is progressing at the nanoscale not only with the objective to reduce time and cost but also to ease the handling and working conditions. Application of nanotechnology in various domains of science has led to the enormous innovations. This field facilitates better understanding as well as treatment of living system, activate biotechnological processes, synthesizing new drugs for targeted delivery and biocompatible materials for sustainable environment. Throughout the world nano science is getting wide propaganda. Its application to medicine is increasing rapidly in order to develop nano-drugs with prolonged availability and efficient delivery through rearrangement of molecules at the nanoscale using molecular interactions for example van der Waals forces, H bonds, electrostatic dipoles and various surface forces.

For most of the past 50 years world food production has outpaced rising demand. World population has doubled since World War II, whereas food production has tripled. In the developing world the calories available per person per day increased from an average of 1,925 calories in 1961 to 2,540 in 1992. World food production has expanded due to the Green Revolution—adoption of crop rotation, the mass production and use of petroleum-based fertilizers and chemical pesticides, expanded irrigation, and the introduction of genetically superior, disease-resistant cultivars. The trend may now be changing for the worse, however. Since about 1990 global grain production has risen only slightly and, despite slower rates of population growth, grain supplies per capita have fallen. In the worst case, Africa now produces nearly 30% less food per person than it did in 1967. As per FAO estimates, world food production would have to double to provide food security for the 8 billion people projected for 2025. By 2050, when world population is projected to be over 9 billion, the situation would be even more challenging.

INTRODUCTION
Canopy management is one of the most important management practices in an orchard. It is the ‘art’ of fruit growing involving manipulation of tree canopies to optimize the production of quality fruits. In fact it forms the basis of precociousness, productivity and longevity of the fruit trees. Canopy management is an important aspect of fruit culture due to its effect on yield, quality, vigour, and the prevention of diseases.
 
In orchard, light is critical to the growth and development of trees and their fruits. The green leaves harvest the sunlight to produce carbohydrates and sugars which are transported to the sites where they are needed – buds, flowers and fruits. Better light penetration into the tree canopy improves tree growth, yield and fruit quality. Training and pruning, affects the tree shape and facilitate exposure of leaves to sunlight. An ideal training strategy centres around the arrangement of plant parts, especially, to develop a better plant architecture that optimizes the utilization of sunlight and promotes productivity. Besides, development of strong scaffold system helps the trees to produce heavy crop loads of quality fruits without any major limb breakage.

INTRODUCTION

The chemical compounds needed for growth and metabolism in plants are termed as nutrients. Mineral nutrition of fruit plants is a vital soil management practice in an orchard. The nutrients are converted to cellular constituents or used for energy purposes through metabolic process. Broadly the essential plant nutrients may be divided into macro-nutrients and micro-nutrients. Macro nutrients are needed in plants in relatively higher amounts than micronutrients.
 
Macro nutrients: C,H, O, N, P, K, S, Ca, Mg. 
Micro nutrients: Fe, Mn, Cu, Zn, Mo, B, Cl, Ni.
 
Altogether 17 elements are considered essential for normal growth and production of a plant.While elements like cobalt, sodium and silicon have been established as essential elements for some plant species and not all. C-H-O matrix accounts for over 90% of the dry matter and is usually 20 to 50% of the fresh weight of the whole plant. Chloride is a most unusual nutrient as it is often present in plants in high concentrations yet its essential requirement is very much lower. Chlorine like Na and K plays an important role in osmoticum. The nutritional needs of fruit trees can be assessed through leaf and soil analysis, tree growth and cropping, and past experience.

INTRODUCTION

With the change in world scenario from plentiful resources to limited with population increasing geometrically, shrinking land and climate change, the pressure on agriculture is mounting continuously. Meeting the nutritional requirements of population by optimum supply of food is the pre-requisite for sustainability of life under such conditions. Rapid urbanization is causing scarcity of cultivable land. Therefore, the productivity per unit area of the crops needs to be increased manifold. Horticulture, in general, has attained a pride status in the field of modern agriculture. However, radical changes are expected in horticultural practices in near future as the situation in terms of area as well as production is not as comfortable as the food grain production.

INTRODUCTION

Fruits of commercial importance comprise various combinations of tissues that may include an expanded ovary, the seed and other plant parts such as the receptacle (apple, strawberry), bract and peduncle (pineapple). They may develop from a single ovary of a flower as in simple fruits (apple, banana, mango, peach, plum, tomato etc.), number of ovaries of a single flower as in aggregate fruits (strawberry) or from a number of ovaries of different flowers as in compound fruits (pineapple). They are derived from members of a wide range of families of both monocotyledonous and dicotyledonous plants. Inspite the huge diversity in origin, structure, composition and climate adaptabilities that exists among different fruits, there is considerable similarity in the pattern of maturation and ripening that occur in different fruits.

INTRODUCTION

Jackfruit (Artocarpus heterophyllus Lam) belongs to family Moraceae. It is popularly known as ‘Poor Man’s food’ in eastern and southern India. It is also known as Kanthal, Kathal, Penasa, Kontaka and Phanas in India. Jackfruit is a very unique fruit crop and common tree of low land tropics and grows well without much care. It has considerable potential but it is yet to receive due attention. It is mainly grown in homestead for domestic uses and as a shade tree in coffee or cardamom plantations. It is cultivated in India, Indonesia, Sri Lanka, Bangladesh, Thailand, Malaysia and Nepal. India is the second largest producer of jackfruit in the world and is considered as ‘Mother land of jackfruit’. In India, it is widely distributed in Assam, Tripura, Bihar Uttar Pradesh, and foot hills of Himalaya, Karnataka, Tamil Nadu, Pondicherry and Maharashtra (Sidhu, 2012). It is seldom grown in an organized form as that of other fruit crops viz. mango, guava, etc. Most of the jackfruit trees are observed in kitchen garden or orchards of other fruit crops, roadside or in forests. Well managed orchards of jackfruit are seen in Panruti area of Pondicherry, where the production is at almost throughout the year. At present the area under jackfruit in the country is 157.58 (000’ ha) and the production is 1572.87 (000’ MT) (Anon. 2015).

INTRODUCTION

Aonla or Indian gooseberry (Emblica officinalis Gaertn.) is an important indigenous minor fruit grown in tropical and subtropical regions of India. It is known with many vernacular names such as amla, aura, amlaki, nelli, amolphal, amlakamu, amlet, amlay. Aonla, cultivation is highly remunerative due to its high productivity even on marginal lands. The plant is quite hardy, heavy bearer giving better income to the farmers. It can be grown successfully in marginal soil and various kinds of wasteland conditions such as sodic and saline soils, ravines, dry and semi dry regions.
