The association of flowers with mankind is evidenced since dawn of the civilization. For many centuries, flowers play an important role in each and every occasions of life and no social function is considered complete without the use of flowers. Flowers are regarded as the symbol of love, beauty and a gift of nature. In India, there is a popular saying that flowers are associated with man from birth till death.

Floriculture can be defined as a specialized branch of horticulture which deals not only with the cultivation of flowers, foliage plants, climbers, trees, shrubs, cacti, succulents, etc., but also their marketing and production of value-added products from them.

Floriculture is increasingly regarded as a viable diversification from the traditional field crops due to higher returns per unit area. Flowers play a cardinal role in human behaviour and culture, bringing tranquillity and peace of mind. From a symbol of love, flowers have transformed into an industry, generating both income as well as employment. During the past few decades, appreciation of the potential of the commercial floriculture has resulted in the blossoming of this field into a viable agri-business option. The varied agro-climatic conditions prevailing in India and wide availability of natural resources are conducive for production of a large number of flowering and ornamental crops almost throughout the year. The commercial production and marketing of flowers and floriculture products have also increased during recent years due to improved marketing and communication facilities, making availability of these throughout the country and generating a huge employment.

Introduction

The improvement of the quality of foods can be made by fortification of foods nutrients quality and quantity in food. It can be a very cost effective public health intervention. As a result of the high consumption pattern of dairy products viz. yogurt, the fortification process will effectively diminish or prevent diseases associated with nutritional deficiencies (Gahruie et al., 2015). However, due to nutrients deficiencies in human population especially in certain stages of life, holding, importing, and consumption of fortified foods is increasing (Preedy et al., 2013). As a general rule, addition of one or more essential nutrients to a food and increasing their concentration in that particular food to levels higher than normal is known as fortification. This is intended at preventing and correcting shortages in one or more micronutrients in the society or specific population groups (Bonner et al., 1999). The major ways of food fortification are (1) commercial and industrial fortification for wheat flour, corn meal, cooking oils, (2) bio-fortification of crops to augment their nutritional value, which can include conventional as well as selective breeding, and genetic engineering and (3) house hold fortification like vitamin D drops. Fermentation has twofold outcome on glycemic index though there are conflicting results after consumption. The reduced glycemic index of fermented food has been featured to the production of short?chain organic acids during fermentation.

Abstract

Carbon is the backbone for the life of all living beings. Carbohydrates are metabolic currency of plants as they provide building blocks for energy and biomass accumulation. Carbohydrates include both structural and Nonstructural carbohydrates. Structural carbohydrates like cellulose and lignin are long chain molecules for the building of plants reserves and structural support. These are main constituents of plant cell wall, stem, stalks etc. Non-structural carbohydrates (NSC) like monosaccharides, disaccharides, oligosaccharides, polysaccharides, sugar alcohols are important constituents in plants metabolism. The Non-structural carbohydrates (NSC) pool is very important for plant to meet the inadequate carbon requirement under night and stressful conditions. The quantity and distribution ratio of NSC in different tissues is an ecophysiological feature to understand the adaptive strategies of plants. Substrate for biosynthesis of NSC produced from photosynthesis. Sucrose and starch majorly involved in transport, energy metabolism, osmoregulation of plants.

Introduction

Agriculture plays important role in boosting economic activity of farmers. Since it transfers new technologies within the knowledge and information system, it has special features related to knowledge, innovation, and those three. Agribusiness farming needs the diffusion of innovation. Many farmers were unable to boost their earnings. The development of the agribusiness and the welfare of the farmer were both significantly influenced by innovation. Diffusion includes three fairly distinct processes i.e. presentation of the new culture element or elements to the society, acceptance by the society, and the integration of the accepted element or elements into the pre-existing culture (Linton, 1936).

The Indian government’s New Education policy (NEP 2020) is apositive improvement in this covid-19 scourge. The main NEP for India happened in 1968, trailed by NEPs in 1986 and 2020 under Narendra Modi. India passed the NEP 2020 on July 29, 2020. It tries to reform education and make the countrymoretaught. K Kasturirangan, the previousheadofISRO, led- the NEP 2020 arrangement council. The decision Government of India vowed to modernise Indian schooling in it selection pronouncement (Saha Mushkan, 2020). Educationassumes a fundamental part in building a country; it chooses the nation’s future and its kin’s fate. The effect will be sturdy concerning the development and advancement of the stateandsubject. In this day and age, schooling is urgent. Pre-freedom and post-autonomy periods show the extension and progress Indian Government. It will alter the way India studies; this is the third correction to the instruction strategy. National education policy 2020 plans changes for all gatherings (Kalyani Pawan, 2020).

ABSTRACT

The major part of the agriculture in India is Rainfed. The increasing pressure of population on land has resulted into over exploitation of land, water and other ecological resources, resulting in water scarcity, land degradation and rapid depletion of ground water-table. Government of India has adopted watershed management strategy to address these problems, but all existing watershed management programmes are mainly fragmented and governed by different departments. This has resulted in formation of providing better service delivery and governance. In this study an attempt is made to identify the scope of convergence between National Rural Employment Guarantee Act (NREGA) with Integrated Watershed Management Programme (IWMP) for generation of social capital and self-employment in the command area of a watershed using geospatial technology.

Ex.No.1. MICROBIAL SPOILAGE OF FRUITS

Fruits are living structures that continue to perform metabolic reactions and sustain physiological processes for a considerable length of time after harvest. The post-harvest infection of fruits by microorganisms may cause serious losses of fruits both in terms of quantity and quality. Initial infection which may be the direct result of mechanical or insect damage is followed by invasion of fruit tissues by secondary infection by common saprophytic organisms. . Many bacteria and fungi, for instance, are involved in decay after harvest. Typical fungi include Alternaria, Botrytis, Colletotrichum, Fusarium, Monilia, Penicillium, and Rhizopus. These fungi are generally weak pathogens, in that they usually infest only weak or damaged fruit. Molds are the most predominant spoilage organisms in fruits. Fungal rots in fruits like apple show brown or cream coloured areas.

Bacterial soft rot caused by Erwinia carotovora is wide spread in fruits that are not very acid. Fruits like straw berries, melons are in direct contact with moist soil and become infected from that source.

Livestock rearing provides triple benefits of income, employment and nutritional security to the society and is important source of subsidiary income to small/marginal farmers and agricultural laborers. Finance is a prerequisite and of paramount importance for setting up of a livestock enterprise whether a dairy farming unit for milk production, sheep or goat unit, piggery unit, dairy/poultry processing unit etc. Provision of credit/loans for the purchase of livestock, feed, veterinary services and insurance against the loss of valuable productive assets play an important role in encouraging new investments in the sector and also in coping with difficult problems such as draught and diseases. Decisions about credit are often most important judgments that people in the livestock enterprise must make. These decisions often determine whether individuals operating in input, production, processing and services based livestock enterprise would succeed in making profit.

The word 'social forestry' was coined by Westoby and used in the ninth Commonwealth Forestry Conference at New Delhi in 1968. In India the term was first used by the National Commission on Agriculture, Government of India in 1976, to denote tree raising programmes to supply firewood, small timber and minor forest products to rural population. Prasad (1985) defined social forestry as forestry outside the conventional forests which primarily aims at providing continuous flow of goods and services for the benefit of people. This implies that the production of forest goods for fulfilling the needs of the local people is social forestry. Thus, conceptually it deals with the people to produce goods such as fuel, fodder, small timber, etc. to meet the needs of local community particularly the underprivileged section (Shah, 1988).

Abstract

Soil quality assessment has been recognized as an important step towards understanding the long term effects of land management practices within agricultural watersheds. Potential soil quality issues include continued high rates of erosion, losses of organic matter, reductions in soil fertility and productivity, as well as chemical and heavy metal contamination. This case study addressed the spatial variability of soil properties and its quality at the watershed level using geostatistical methods. Soil samples from the 0- to 20-cm depth were collected on a 100- by 100-m grid across an 88-ha watershed at Sakaliseripalli village in the Nalgonda District in Andhra Pradesh State, India. Geostatistical analysis showed that most of the soil parameters were moderately spatially dependent. An assessment framework, that included a minimum data set, linear scoring technique, and additive indices, was used to evaluate the soil quality index (SQI). Through principal component analysis, cation exchange capacity, exchangeable Na percentage, DTPA-extractable Zn, available P, available water, and dehydrogenase activity have been emerged as the most important indicators for evaluating soil quality. A kriged map of SQI was prepared for the watershed. The SQI was found to be higher in irrigated systems than under rainfed conditions. In the study, potential soil loss calculated using the Universal Soil Loss Equation and crop yield were identified as the quantifiable management goals; the results indicated that soils having higher soil quality indices were more productive and less erosion prone.

1. INTRODUCTION

Food processing industries are engaged in production of different types of processed products and generate various types of wastes. These wastes, whether solid or liquid, on one hand are a direct loss to the producer or manufacturer and on the other hand create environmental pollution, if not disposed properly. Therefore, the processors would always like to minimize these wastes. The generation of wastes not only cause economic losses but would also require additional cost for their management and disposal. As a matter of fact, it is often estimated that proper use of efficient machinery and careful handling during various operations can lead to more than 50% reduction in losses.

In general, the wastes from the food processing industries are either not utilized or primarily utilized as animal feed, fertilizer and in preparation of by-products on a limited extent. Many of the wastes such as cuttings and shreds from the fruit and vegetable processing industry can be used as animal feed. Fruit and vegetables wastes can also be used for extraction of starch, pectin, natural colouring matter, fat, essential oils etc. Wheat and maize bran alongwith palm kernel are used for the production of feed for chickens. Various oils and oleoresins having enormous pharmaceutical properties can be obtained from the spice processing industry.

Fermentation is a cheap and energy efficient means of preserving perishable raw materials. It commonly does not require any sophisticated equipment, neither is the storage of fermented products a big issue. Fermented foods play an important role in providing food security, enhancing livelihoods and improving the nutrition and social well being of millions of people around the world, particularly the marginalised and vulnerable population across the developing countries.

The response to selection is the change produced in the population mean through selection. This is achieved through selecting as parents of the next generation, individuals with highest genetic merit and whose progeny will, as a group, have the highest possible genetic merit for the trait in question. 

The complement system is a group of about 20 heat labile plasma proteins which constitute nearly 10% of total serum proteins. These are important in activation of phagocytes, control of inflammation and cytolysis. They form one of the major immune defense systems of the body. The complement system plays important role both in innate and adaptive immune system. The main functions of complement are chemotaxis; opsonization and cell activation; immune clearance of immune complexes from circulation; lysis of target cells; triggering and amplification of inflammatory reactions and development of antibody responses. Evolutionary, the system is very ancient and is present even in invertebrate organisms like starfish and worms.

ABSTRACT

The study was undertaken to assess the effectiveness of ICT-Enabled Village Information Centres (VICs) with special reference to dairy farming in Tamil Nadu. Ex-post-facto research design was followed, wherein 180 users and 90 non-users of VICs constituting 270 dairy farmers covering three ICT-VIC initiatives viz., Tamil Nadu Veterinary and Animal Sciences University (TANUVAS), M.S.Swaminathan Research Foundation (MSSRF) and n-Logue communication in Tamil Nadu were selected using random sampling technique. Data collected through personal interviews were analysed using appropriate statistical tools.

Management approaches to soil, including problems of soil degradation and low soil fertility, have recently undergone major changes. The earlier concept was to concentrate on achieving high levels of production from the more fertile areas, leaving the marginal lands for extensive use only. Steeply sloping and highly drought-prone areas were mostly left without any cultivation as production from these areas was hardly cost effective. Soil constraints were to be overcome by inputs like improved crop varieties, fertilizers, chemical control of pests and diseases, and the use of irrigation.

The approach of use of newly developed high yielding crop varieties, improved agronomic management practices, use of chemical fertilizers, efficient water management and timely plant protection measures has been successful in achieving large increases in crop productivity in recent years. On the other hand, continuous application of fertilizers at higher rates leads to environmental problems. Yield responses to fertilizers have declined because of soil physical degradation and micronutrient deficiencies. Above all, large numbers of poor farmers simply can neither afford high levels of fertilizers and other purchased inputs, nor do they have the capital to take on the risk involved in their use. Increasing the area under irrigation has also run into severe constraints in the form of limits to available freshwater resources.

Introduction

Indian arid zone is one of the largest subtropical deserts of the world of which 20% is arid and rest is semi-arid. Hot arid zone is spread over 31.7 million ha area and mainly confined in the states of Rajasthan, Gujarat, Andhra Pradesh, Punjab and Haryana. The major part of hot arid region of the country lies in western Rajasthan (19.62 mha) followed by North-western Gujarat (2.16 mha). It is characterized by high aridity index, extremes of temperature low and variable precipitation, very high wind velocity and dust storm, high soil pH, high infiltration rate, very limited availability of groundwater and saline ground irrigation water (More, 2010). Under such harsh climatic conditions cultivation of vegetable crops in open condition results in very low and poor-quality yield which fetches less return per unit area. By creating the suitable micro-climate for plant growth round the year cultivation of vegetables can be done under adverse climatic conditions. It is possible through protected cultivation which has tremendous scope in peri-urban areas of the country (Singh and Sirohi, 2004). It is the best way to increase the productivity and quality of vegetables, especially cucurbits. India is the second largest producer of vegetables in the world next only to China. Presently India has 178.17 million tonnes of total vegetable production, but the productivity and quality of most of the vegetable crops is very poor (17.40 t/ ha) due to several biotic and abiotic stresses due to open field cultivation. In Rajasthan, the total production of vegetables is very less i.e. only 1.81 million tonnes from an area of 0.17 m ha with a productivity of 10.66 t/ ha.

With diverse agro-climatic conditions, India produces a wide variety of horticultural crops and out of these crops and out of these apple (Malus x domestica Borkh.) occupies a prominent position in India. It is processed into different products like juice, concentrates, wine, cider, canned slices etc. Apple processing is one of the major industries in countries of the world including India, where it is processed in different states like H.P, Jammu and Kashmir and Uttarakhand. Apple pomace is a left-over residue after juice extraction containing peel, seeds and remaining solid parts and represents about 25-35% of the weight of the fresh apple processed. At prasent, it is a waste and its disposal is a major environmental problem (Plate 1). Being precious natural resources its utilization is a challenge and opportunity to the scientists and technologists. It may be a good substrate for the pectin esterase enzyme, animal feed, citric acid, ethanol and biocolour production. It could be a good substrate for the production of microbial colours under SSF which otherwise require a costlier medium for its production. Different products using solid state fermentation of apple pomace forms the subject matter of this chapter. Here the efforts made to utilize apple pomace especially to explore the possibility of making value added products using Solid State Fermentation (SSF) have been summarized.

India is one of the few countries in the world, which has contributed richly to the international livestock gene pool. Small animal particularly sheep and goat biodiversity in India is characterized by high degree of endemism in different agro climatic regions, and has led to the development of various breeds/strains that are well adapted to specific set of environmental conditions. These breeds have generally been named after their place of origin and some based on their prominent characteristics. Indigenous sheep and goat contribute greatly to the agrarian economy, especially in areas where crop and dairy farming are not economical, and play an important role in the livelihood of a large proportion of small and marginal farmers and landless laborers. Sheep and Goat rearing and production has been the important source for sustainable livelihood of the rural people mainly in arid, semi-arid and temperate regions of India as it serves their various needs and provides an unceasing source of income round the year.

Introduction

As per the reports of the United Nations Organization (UNO), the world population is expected to increase to about 9.7 billion by 2050 and to 10.4 billion by the mid-2080s. The increasing population will result in food scarcity and hunger across the world. To meet the demand for food to feed the people and meet the present aim of WHO of “Zero Hunger by 2030”, agriculture and livestock production needs to be increased. However, according to the ICAR Vision 2050 document, growth of the livestock sector is expected to be higher than the agriculture due to different factors like urbanization and changing food habits among the population residing in the urban area, lack of technology among the small and marginal farmers, reducing operational land, water scarcity, reduced irrigation infrastructure, climate change, etc. to name a few. But to achieve food security through the livestock sector, animal health and production of the animals need to be addressed.
