Value addition is the most talked about word in food processing industry, particularly in export oriented fish processing industry because of the increased realization of valuable foreign exchange. Value can be added to fish and fishery products according to the requirements of different markets. These products range from live fish and shellfish to ready to serve convenience products. As far as fish processing industry is concerned value addition is one of the possible approaches to raise profitability since this industry is becoming highly competitive and increasingly expensive.

There is great demand for seafood/seafood based products in ready to eat “convenience” form. A number of such diverse products have already invaded the western markets. One factor responsible for such a situation is more and more women getting educated and taking up employment. Reasonably good expendable income, education, awareness and consciousness towards hygiene and health, increased emphasis on leisure pursuits etc. are some of the other reasons.

Marketing of value added products is completely different from the traditional seafood trade. It is dynamic, sensitive, complex and very expensive. Market surveys, packaging and advertising are a few of the very important areas, which ultimately determine the successful movement of a new product. Most of the market channels currently used is not suitable to trade value added products. A new appropriate channel would be the super market chains which want to procure directly from the source of supply. Appearance, packaging and display are all important factors leading to successful marketing of any new value added product. The retail pack must be clean, crisp and clear and make the contents appear attractive to the consumer. The consumer must be given confidence to experiment with a new product launched in the market. Packaging requirements change with product form, target group, market area, species used and so on. The latest packaging must also keep abreast with the latest technology.

Abstract

Prolactin is a hormone secreted predominantly from anterior pituitary and imparts important roles related to development of mammary gland, reproductive behaviour and immune response. The objective of this study was to explore restriction fragment length polymorphism (RFLP) pattern of prolactin gene, to estimate gene and genotype frequencies of different restriction fragments and to study the effect of genotypes on milk production and reproduction traits in crossbred cattle Bos taurus x Bos indicus (Jersey x HF x Sahiwal).The present study investigated RFLP within 156bp amplification products of the bovine prolactin gene exon 3 in 30 crossbred cattles selected randomly from a herd using specific set of primers (Forward primer- 5’- CGA GTC CTT ATG AGC TTG ATT CTT -3’ and reverse primer- 5’- GCC TTC CAG AAG TCG TTT GTT TTC -3’). Restriction enzyme digestion with RsaI revealed three patterns in crossbred cattle, one having 156bp fragment (AA genotype), second having 156bp, 82bp and 74bp fragments (AB genotype) and third having 82bp and 74bp fragments (BB genotype) indicating genetic polymorphism. The gene and genotype frequencies in crossbred cattle were found to be 0.78 and 0.22 for A and B alleles and 0.70, 0.17 and 0.13 for AA, AB and BB genotypes, respectively.

ABSTRACT

The estimation of the water requirement of crop is one of the basic needs for crop planning on the farm and for the planning of any irrigation project. Water requirements of crops include the losses due to Evapotranspiration (ET) plus the losses during the application of irrigation water (unavailable losses) and the quantity of water required for special operations such as transplanting and leaching of excess salts for crop growth. It is therefore necessary to estimate the ET and Crop Water Requirement (CWR) for the efficient use of water and increased crop production. In the present study, meteorological data were collected and the crop ET (ETc) and the CWR were estimated using FAO Penmann – Monteith method for the cropping pattern of the Buthangudy canal command area situated at a distance of 2Km from the popular village Sethiathope, Cuddalore district, of Tamil Nadu, India, which is located in between the Kumbhakonam – Chennai NH – 45 main road. The methodology combines the capability of GIS and CWR to produce maps showing spatial distribution of water resources over large areas.

Introduction

The sun is an abundant source of solar energy (average value on horizontal surface 6 kW m^-2 day^-1), which is freely available. This huge source of energy is non-polluting and inexhaustible in nature. It has the potential of supplementing the conventional energy sources to a great extent. There is acute shortage of conventional energy sources, which affects the overall development. Work on the utilization of such a huge, non-polluting and everlasting energy source has been carried out at CAZRI, Jodhpur for various domestic, industrial and agricultural applications in order to supplement the energy demand. This includes the development of a lot of solar thermal devices, such as, solar still, solar dryer, solar cooker, animal feed solar cooker, solar candle device and cool chamber. The details of some of these devices are given as following.

Introduction

In the animal kingdom, there are many animals with a concrete social system in their ranks. Animals like lions, wolves, and apes have complex social systems in their lives. And what is the most important thing in a functional social system? It’s communication! Communication is the most important function in any social system, which binds that system.

And what organism has the most complex social system? It’s humans. Thus, the human social system requires a very complex communication system.

In genetic studies it is necessary to distinguish two causes of correlation; is chiefly pleiotropy, though linkage is a cause of transient correlation, particularly in populations derived from crosses between divergent strains. Pleiotropy is simply the property of a gene whereby it affects two or more characters, so that if the gene is segregating it causes simultaneous variation in the characters as affects. For example, genes that increase growth rate increase both stature and weight, so that they tend to cause correlation between these two characters. The degree of correlation arising from pleiotropy expresses the extent to which two characters are influenced by the same genes. But the correlation resulting from pleiotropy is the overall, or net, effect of all the segregating genes that affect both characters. Some genes may increase both characters, while others increase one and reduce the other the former tend to cause a positive correlation the latter a negative one. So pleiotropy does not necessarily cause a detectable correlation. The correlation resulting from environmental causes is the overall effect of all the environmental factors that vary; some may tend to cause a positive correlation, others a negative one.

The traditional medicines are actually used in human for number of years and therefore its clinical existence comes as a presumption. However, for bringing more objectivity and also to confirm traditional claims, systematic clinical trials are necessary. In Ayurvedic medicine research, clinical experiences, observations or available data becomes a starting point. In conventional drug research it comes at the last. Thus, the drug discovery based on Ayurveda follows a ‘Reverse Pharmacology’ path546.

Nevertheless, all the critical Pharmacopoeial tests such as dissolution time, microbial, pesticide and heavy metals contamination etc. must be in accordance with global standards. It is important to ensure that all the Ayurvedic medicine manufacture is in accordance with Current Good Manufacturing Procedures for herbal products547,548. There have been concerns about quality standards and safety issues of herbal medicines549. The need for new regulations for botanical medicines has also been frequently stressed and some such regulations are coming in force in different parts of the world550,551.

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.
