Introduction
India possesses wide range of climatic and physio-geographical conditions, which are favourable for the production of various kinds of horticultural crops such as fruits, vegetables, flowers, nuts, spices, plantation crops (coco nut, cashew nut and cocoa) etc. The production of fruits and vegetables (F&Vs) in India is 81.2 million tonnes and 162.2 million tonnes from an area of 6.9 million hectares and 9.2 million hectares respectively during 2012-13 (NHB, 2013).  India is the second largest producer of F&Vs in the world after China. India’s share in the world production of F&Vs is 11.84 per cent and 13.36 per cent respectively (Lagzi, 2013). The importance of horticultural sector can be gauged from the fact that the contribution of horticulture sector in agricultural gross domestic product (agri-GDP) stands at around 30 per cent (Economic Survey, 2013-14).

Agricultural sector need efficient functioning of its markets to stimulate economic growth and incomes of the large rural population dependent on agriculture. More than three-fifths of India’s population draws their livelihood from agriculture that adds just one-fifth to its GDP. There should be obvious serious concerns about efficient functioning of this sector both in terms of its output / productivity and its marketing. While output and productivity are supply side factors, markets provide an intermediate link between producers and final demand by consumers. An efficient marketing system is pertinent for optimization of the resource use, output management, improving farm incomes, growth of agro -based industry and enhancing value addition. The efficient markets are also important for the stable consumer prices, higher returns to the farmers and reducing post harvest losses. Efficiently functioning markets add to welfare of producers as well as consumers. For markets to work efficiently it is pertinent to link the farm gate with retail outlets so as to reduce losses and marketing costs. However, it requires an institutional framework and infrastructure to prepare the produce in the form demanded by the consumers.

Abstract

India is the prevalent prime producer of moringa [drumstick] with an annual production of 2.2 million tonnes of tender fruits from an area of 38,000 ha. Among the states, Andhra Pradesh leads in both area and production [15,665 ha] followed by Karnataka [10,280 ha] and Tamil Nadu [7,408 ha]. In other states, it occupies an area of 4,613 ha. Tamil Nadu is the pioneering state in so much as it has varied genotypes from diversified geographical areas, as well as introductions from Sir Lanka. Farmers found that growing moringa crops during summer season was remunerative. Thus, moringa gained a foothold as a summer vegetable. Its unique flavour and aroma became very popular. For South Indian any meal without moringa and pulses is considered incomplete. The demand for the moringa pod also increased due to increased urban settlements and migration of people to urban colonies. Based on the significance of moringa in the human diet this study might more viable with the specific objectives of to assessing the marketing strategies for promotion Periyakulam annual moringa seeds in Tamil Nadu.

Abstract

In this paper we studied the economics of marigold flower in Eastern Uttar Pradish Floriculture has assumed a definite commercial status. Its potential as a viable agribusiness has also been recognized. Diverse agro-climatic conditions permit perennial production in one part of the country. This sector provides employment to millions. Floriculture was practiced only on small farms but now a few large ones have been set up. The collected information were analyzed and presented in tabular form. Making small size mala on small and large farms were higher than the large size mala. There return per Rupee of investment were estimated that the  1.66, 2.08 and  1.84, in the account of small size, large size farms and overall, respectively. The percentage of total marigold produce sale indifferent marketing channels indicated that 90 per cent produce sold in II marketing channel where as next 10 per cent marigold flowers sold directly to the consumer i.e. channel I. The retailer’s level the marigold flowers were sold to the consumers in different forms such as flower basket, bouquet and in other farms as demanded by the buyers. The marketing cost and marketing margin (Price spread) may differ from the channel to channel. The marketing cost and margins also depend upon the form in which the product reaches the ultimate consumers.

In the recent years it has been increasingly realized that only increase in physical production of crops no longer guarantees the smooth development of agriculture at both the farm and the national economy levels unless and until it is linked with efficient system of marketing. As such, now a day in planning for agricultural development specially in developing economies marketing system had drawn much more attention than customarily assigned to it. Efficient marketing of agricultural commodities in general and fruits crops in particular plays an important role in safeguarding the interest of producer as well as consumer.

Introduction

India is the largest producer of vegetables in the world after China, contributes over 13% to world vegetable production and occupies first position in the production of cauliflower, second in onion and third in cabbage. Amongst vegetables, India is the largest producer of Ginger and Okra and ranks second in Potatoes production (10%), Onions, Cauliflowers, Brinjal, and Cabbages, etc. During 2012-13, India exported vegetables worth  1516.33 crores. The average productivity of vegetables in the country is 17.61 t/ha.

Introduction

Our national food security depends on our ability to conserve all our biological wealth.

Dr. M.S. Swaminathan (Biodiversity, Principle and Conservation, 2002)

Variation is the law of the nature. It occurs everywhere and every moment. The variety and variability of organisms and ecosystem is referred to as biological diversity. Biodiversity is the most significant asset and constitutes enduring resources for supporting the continued existence of human societies. The agricultural biological diversity more commonly referred to as agro-biodiversity, has been fast emerging as a strong, evolutionary divergent line from the biodiversity, which deals with life form at large (Kumar and Asija , 2002). Agro-biodiversity is basic to the farming system.

Abstract

India, ranks first in marigold production among the loose flowers followed by chrysanthemum, jasmine and tuberose. Today, there is huge demand for natural colours of marigold, calendula, hibiscus, Petunia etc.in the international market.
 
A study on primary data was done to examine the production and marketing cost and profitability of marigold flowers. Data were collected through multistage sampling technique from farmers of Bhaderwah tehsil of Doda district in Jammu And Kashmir State.

Introduction

Mushrooms are very nutritious products that can be generated from lignocellulosic waste materials; and are in rich in crude fibrend protein. In fact, mushrooms also contain low fat, low calories and good vitamins. In addition, many mushrooms possess multi-functional medicinal properties. Edible mushrooms once called the “food of the gods” and still treated as a garnish or delicacy can be taken regularly as part of the human diet or be treated as healthy food or as functional food. The extractable products from medicinal mushrooms, designed to supplement the human diet not as regular food, but as the enhancement of health and fitness, can be classified into the category of dietary supplements/mushroom nutriceuticals (Chang and Buswell, 1996).

Introduction

Potato is the fourth most important food crop in India after rice, wheat and maize. India is second largest producer of the world after China having a production of more than 45 million tones. The major producers of potato  are Uttar Pradesh (14.43 million tones) followed by West Bengal (11.6 million tones) and Bihar (6.6 million tones) during 2012-13. In Uttar Pradesh during rabi 2013-14 the total production of potato is expected to be 46.2 million tones. The major potato producing districts in Uttar Pradesh are Agra, Farrukhabad, Firozabad, Hathras, Kannauj and Barabanki. Potato arrival is maximum in Farrukhabad, Kanpur and Varanasi  APMC Mandi and the highest arrival is in the month of march and lowest is in the month of October.

Introduction

In recent past vegetable cultivation took enormous turn over because of increased population, inflow of tourists and increased per capita income in the Bay Islands as well as India. Population in these islands is increasing due to immigration of people from main land and the land area is limited.

Abstract

This paper illustrates the summary of work by different groups on the potential for agribusiness and marketing research by agricultural economists over the past decade. Methodology to establish research priorities in agribusiness and marketing are reviewed. This review leads to a consideration of the agribusiness research issues including the funding sources, identifying users of agribusiness research, data needs, and limitations of agribusiness research programs. This paper also presents a potpourri of  suggested research initiatives in agribusiness research for agricultural economists. Research in these areas may be difficult for a number of reasons including, decreased reliance on economic theory as the soleparadigm, providing competitive advantage to a single agribusiness firm while balancing public and private needs, funding sources, and data confidentiality. Recommendations for outlets for academic research are presented.

Introduction

Floriculture is the branch of horticulture concerning cultivation of flowering and ornamental plants for gardens and floristry. It includes cut flowers, cut greens, bedding plant, houseplants, flowering garden and pot plants etc. It is a fast growing industry. Urbanization and rising living standards of the people has lead to steady increase in demand of flowers and flower products making floriculture as one of the most important commercial trades in Agriculture. It has been found that commercial floriculture has higher potential per unit area than most of the field crops and is therefore a lucrative business.

Introduction

Marketing as we know plays an important role in the proper utilization of any crop irrespective of its type and variety. Unless and until producer is not able to market his crop efficiently, he will not get the remunerative price for his produce. For the past few years marketing part is getting more attention than production as giving 100 per cent to the production side only will not pay much to the farmers. Proper distribution of the product to its proper place where demand is more and that too in time is also important. Government is also encouraging the farmers for marketing of their produce in a right and effective manner. No doubt every crop is in need of efficient marketing but fruits because of more perishable in nature require advanced marketing facilities.

In India farming was traditionally subsistence in nature but with the passage of time, the nature of farming has changed to commercialized system faming. With the commercialization of farming, price of the product along with its quality has become an important factor in marketing. Quality and safety issues have also gradually gained importance as people in general have become conscious and aware of the hygiene, health and safety issues related food and food products. Perishability of food items requires more emphasis on its quality and safety. The formal system of regulations in quality and safety standard has been mainly the contribution of the developed world. The International market has set a high standard of quality and safety of agriculture products. In the country the standardization of quality and safety of agricultural products has gained momentum in the last 10-15 years.

Indian agriculture – the back bone of our economy accounts for about 65 per cent of the country’s employment and 20 per cent the total export earnings. Despite a drastic increase in the food grains production during the last five decades, the profit margins of farmers particularly small and medium farmers has declined due to certain serious problems like declining water table, deterioration in soil health, outbreaks of new pests diseases and weeds, and environmental pollution etc. With the globalization of market, the farmers will have to change themselves from mere producers’ in the domestic markets to producer cum seller in a wider market sense in order to best realize the returns for his investments, risks and efforts. Now the focus should be on high quality produce, low cost of production and high productivity.

Meaning of Advertising

According to Concise Oxford Dictionary, the word to advertise means to make generally or publicly with a view to increasing sales. The word ‘advertising’ is derived from the Latin word ‘advertese’ which means ‘to turn (the mind) to’. Advertising means providing adequate knowledge about some special product/service/idea to potential consumers so that they are stimulated to buy it. Adequate knowledge about a product means to let people know the name of the product, its function, size, price and place of its availability. The organizations providing service or idea give information regarding where, how and on what conditions their service or idea can be made available and how the same can be helpful to the people. Today is the age of competition. Consumers buy commodities after careful consideration. Under the circumstances, manufacturers are faced with the problem of how to motivate the consumers to buy their product. To find a solution to this problem, manufacturers make use of advertising.

Meaning of Marketing

Marketing is an important function of management. Marketing makes the economy strong. Production is meaningless unless the goods and services are exchanged for money. Marketing is related with movement of good from producer to consumer.

Various people have defined marketing differently. A majority of people consider it as selling while some people prefer to call it shopping. Similarly, some people call it merchandising. All these meanings of marketing are partially correct.

Marketing is the sum total of all those activities which move goods and services from the producers to the consumers.

Introduction

Agriculture, in most developing countries is the major industry. More than 50 percent of the labour is working in this sector and its industrial and commercial branches. In these countries, also more than 50 percent of the households‘ incomes are spent for low quality and value foods. Inefficiency of the agricultural products marketing system is the starting place of these problems.

Introduction

Agriculture is an important sector for countries like India, who have majority of its population, directly or indirectly depend upon agriculture. The sector which feeds the majority of population of any country needs special attention for its all round development. Marketing is such a crucial aspect related to agriculture that is probably not developed in any of such countries which largely depends upon agriculture. Underdeveloped and lack of resources are the main reasons behind the underdeveloped nature of agricultural marketing. In simple terms, agricultural marketing means the buying and selling of agricultural produce. The Indian council of Agricultural Research defined involvement of three important functions, namely assembling, preparation for consumption and distribution.

Introduction

The National Commission on Agriculture defined agricultural marketing as a process which starts with a decision to produce a saleable farm commodity and it involves all aspects of market structure of system, both functional and institutional, based on technical and economic considerations and includes pre and post- harvest operations, assembling, grading, storage, transportation and distribution. The Indian council of Agricultural Research defined involvement of three important functions, namely (a) assembling (concentration) (b) preparation for consumption (processing) and (c) distribution.

In the recent years, rural markets have acquired significance in developing countries like India and China, as well as the overall growth of the economy has resulted into substantial increase in the purchasing power of the rural communities. On account of technological change during 1966-67, rural areas are consuming a large quantity of industrial and urban manufactured products. In this context, a special marketing strategy i.e. rural marketing has taken place. Sometimes, rural marketing is mystified with agricultural marketing the later denotes marketing of agricultural commodities of the rural areas to the urban consumers or industrial consumers, whereas rural marketing involves delivering manufactured or processed inputs or services to rural producers or consumers or rural marketing determines the carrying out of business activities bringing in the flow of goods from urban sectors to the rural regions of the country as well as the marketing of various products manufactured by the non-agricultural workers from rural to urban areas. Also, when we consider the situation of developing countries, there is a picture that comes out, huge market for the development products as well as the labour support.

Introduction

Labour markets, poverty and inequality in the growth process
 
The theoretical discussion on the changes in the incidence of poverty and inequality in the growth process of agrarian economies from low levels of income has been a major topic in development economics. The impact of growth is delineated through the labour market, and any predictions about the impact on poverty and inequality must be based on some implicit or explicit view of the structure of labour markets and their functioning.

Introduction

The term value chain was first used and popularized by Michael Porter in his book “Competitive Advantage: Creating and Sustaining Superior Performance” in 1985.

The value chain concept separates useful activities which allow the company as a whole to gain competitive advantage from the wasteful activities (which hinder the company from getting a lead in the market). Focusing on the value-creating activities could give the company many advantages. For example, the ability to charge higher prices; lower cost of manufacture; better brand image, faster response to threats or opportunities.

Introduction

Agriculture is the backbone of Indian economy and helps the system as a whole for socio-economy development of the country. Despite 51 per cent of arable land of total geographical area and about 100 million hectares of potential irrigated area, the highest for any country in the world, unfortunately the contribution of agriculture to the grass domestic product is as low as 22 per cent. India is endowed with a wide spectrum of agro climatic conditions and a large variety of fruit crops ranging from tropical, sub­tropical and temperate are grown. In India, the area under fruit crops is 3.5 Mha with a production 45MT which accounts 9.6 % of total worlds production and ranks 2nd in fruit production (Anon., 2005). The country has become self-sufficient in food grains production, second largest producer of fruits and vegetables, but still the per capita consumption per day is hardly of the order of 70 g for fruits and 140 g for vegetables.

Organizations Indebtedness Towards Society

The organizations in the present world operate as an open system by having ongoing interactions with the society for their existence and effective functioning. There is an interdependence between corporations and societies and as such, company’s activities have a direct impact on the communities with which they work.  As a part of such interactions, the organizations use valuable resources of the society, for producing goods and services, which are exchanged with the customers for a profit margin. Due to these exchanges, the business organizations take away the profits reflecting the debt they owe to the society and the world.

Introduction

Survey sampling is a method of drawing inference about the characteristics of a population by securing a sample. Sample survey techniques are extensively used by government bodies throughout the world and researchers for assessing, for planning and for projection future economy.In a sample survey, the final step of the analysis and drawing inferences from a sample to a population is a very vital and fascinating issue. Since the results of the survey are the basis for policy making, it is the most essential part of the sample survey and should be handled carefully.The object of designing a sample survey is to minimize the error in the final estimates. Any survey involving data collection and analysis of the data is subject to a variety of errors. The errors may be classified into two groups viz., (i) non-sampling errors (ii) sampling errors.

Agriculture occupies a significant place in the economy of India. It contributes nearly 20% to the Gross Domestic Product [GDP] and provides employment to around two-thirds of nation’s population Agricultural commodity exports account for nearly 20 per cent of the total export earnings of the country. The agricultural produce sector has been one of the most important components of Indian economy. Considerable progress has since been achieved in scaling new heights in the production of foodgrains, commercial crops like cotton, sugarcane, tea etc., fruits, vegetables and milk. The increasing trend of agricultural production has brought, in its wake, new challenges in terms of finding market for the marketed surplus. There is also pressure from all segments of agricultural economy to respond to the challenges and opportunities that the global markets offer in the liberalized trade regime. To benefit the farming community from the new global market access opportunities, the internal agricultural marketing system in the country also needs to be integrated and strengthened. In particular the market system has to be revitalized to a) provide incentives to farmer to produce more; b) convey the changing needs of the consumers to the producers to enable production r burning; c) foster true competition among the market players and d) to enhance the share of farmers in the ultimate price of his agricultural produce.

Price mechanism is an economic term that refers to the buyers and sellers who negotiate prices of goods or services depending on demand and supply. A price mechanism or market-based mechanism refers to a wide variety of ways to match up buyers and sellers through price rationing.An example of a price mechanism uses announced bid and ask prices. Generally speaking, when two parties wish to engage in a trade, the purchaser will announce a price he is willing to pay (the bid price) and seller will announce a price he is willing to accept (the ask price).

Sugar originated from the Arabic word “sharkara” and is derived from the sanskrit world “sharkara”. Sugar is an important part of the daily diet and  forming a class of edible substances which includes  sucrose, lactose, and fructose. It provides the human body with requisite carbohydrates and is basically extracted from sugar cane and sugar beet.  Found in fruits, honey, sorghum, sugar maple and in several other sources, it is the main ingredient of candy which is loved by children the world over. Yet, it has been  blamed for causing tooth decay and excess consumption of sugar has been associated with a host of ailments like diabetes, obesity, weight gain, depression, joint pain, fatigue and insulin resistance and even cancer.

Among fresh vegetables, onion, tomato and mushroom are reported to be highly export competitive. India ranks first in the world accounting for around 21 per cent of the world area, planted to onion. Globally, the country occupies the second position, after China, in onion production with a production share of around 14 per cent. Productivity of onion is low at around 11.4 metric ton/ha, which is significantly lower than the world average of 17.3 metric ton/ha. Besides India and China, the other major onion-producing countries are Turkey, Pakistan, Iran, Japan, Brazil, United States of America and Spain. It is produced for both domestic consumption as well as exports. India produces all varieties of onion - pink, red, yellow and white, big or small.

Potato is a major food crop, grown in more than 100 countries in the world and it is one of the major commercial crops grown in India. India ranks third by contributing around 7.5% to the world’s production. During 2006-07, 27 million tonnes was produced in an area of about 1.5 million ha. However, potato consumption per capita in India (14.8 kg/head/year) is one of the lowest in the world and hardly one per cent of the potato is processed.

Setting price is a critical component of successful marketing. Vegetable growers have a greater level of control than most other growers over marketable yields, input costs and price. The closer a grower is to the consumer, the more control over price the grower has. Buyers perceive price to represent value of the product. Underpricing, or pricing too low, gives the perception that the product is inferior, while setting the price too high often drives customers away. Many growers make the mistake of setting the price too low at the beginning of the marketing season when competition is less and demand is strong and then find it difficult to increase price later in the season. Before setting price, gauge the level of competition and the consumer demand for your product. For example, organic produce may have a stronger demand in urban areas, so prices can be set at a higher level. Also, early-season produce, such as tomatoes, has high demand with little competition in most markets, resulting in a higher price range.

Basmati Rice

Basmati Rice is a simple grain, yet throughout history it has been on royal menus of various cultures as the main dish. From the pilav of Turkey, polou of Persia, pilafs of the Steppes, the isotos and paellas of the Mediterranean, to the pulau of India it has been served to great sultans, maharajahs, shahs and emperors. Spices, nuts, dried fruits, vegetables and herbs are a natural for Basmati rice. Basmati rice transforms rice dishes into extraordinary meals. Also known as the “Queen of Rice”, this highly aromatic grain that is long and elegantly thin, has originated from Vasumati which means earth recognized by its fragrance. The full exposition of the word is from Hindi. Bas originating from Prakrit Vas which has a sanskrit root- Vasay connoting aroma; and mati from mayup meaning ingrained from the origin. Common usage has changed Vas to Bas while joining bas and mayup the latter changed to mati.. Thus the word Basmati originated.

Pulses are important food crops due to their high protein and essential amino acid content. Pulses are used as food and animal feed. India is the world’s largest producer, importer and consumer of pulses. Many exporting countries are dependent on India for marketing their pulses. Even though India is the world’s largest producer and consumer of pulses still there is a gap of 2-3 million tonnes between the production and consumption of pulses in the country and the gap is met through imports.

Random workplace surveys in the UK have proven that the staff can get pretty steamed up over hot drinks. Nine years ago, London Underground staff, in fact, threatened to go on strike when kettles were introduced to replace tea urns. Their grouse: it will make them late for shifts. When the credit crunch dried up the free watering holes in many companies, a survey by uSwitchforbusiness.com in 2010 claimed that trouble was brewing. It warned: "Cutting out the free cuppas may add to the bottom line, but there may be a far greater price to be paid in staff morale." Tea or coffee - free or not - is the preferred poison at work.

Prices of major spices such as chillies, jeera, turmeric and cardamom are being driven to the ground by higher production, poor export earnings and a lack of working capital with traders to hold the stocks. Last December, all these spices were at record highs. With the prices ruling high last year, the acreage of most of the spices has increased this year, indicating excess production. The chilli acreage has increased by 15% to 20% while the land under jeera crop is estimated to have gone up by over 26%. The turmeric production is heading for a historic high of 82 lakh bags (each bag of 70 kg) and cardamom is having a bumper harvest.

Cotton, the traditional and important commercial crop has been in cultivation in India for more than five thousand years. Though synthetic / man-made fibre has made inroads, cotton deserves the prime position not only in India but also in the world. The Northern hemisphere accounts for more than 90% of the total world production. Whereas countries like China, US and India together account for 50% of the production in the world. In India, cotton farming provides livelihood for over 4 million farm families. Various allied activities like ginning, spinning, weaving, textile processing, garment manufacturing, marketing etc., provide employment to several million people.

Fats and oils are one of the five essential ingredients of human diet. The four others are protein, carbohydrates, minerals, and vitamins. In balanced diet, the requirement of oils and fats per person per day is around 35 gm. In India, the major source of oils and fats is of vegetable origin; butter from animal milk also serves as a fat, though. In the nine major oilseeds, which are groundnut, rapseed /mustered seed, soya been, seasam seeds, sun flower seed niger seed, castor seed and linseed, out of these   seven are essentially edible. Among these seven, by far the most important are groundnut,  rapeseed/mustard seed, and soya bean. These three edible oilseeds account for a little over 80% of-the-total production of nine oilseeds, which include even two non-edible oilseeds, namely castor seed and linseed. As a matter of fact, edible oilseeds as such contribute nearly 95% to the total production of all cultivated oilseeds together.

The first use of rubber was by the Olmecs, who centuries later passed on the knowledge of natural latex from the Hevea tree in 1600 BC to the ancient Mayans. They boiled the harvested latex to make a ball for a Mesoamerican ballgame.

Liquid milk is the cheapest form of milk whereas value added products like yoghurt and paneer, already popular in India are ways to earn a higher income with some raw materials. Farms should focus on dairy herd improvement, herd management etc. Milk and dairy products are always very helpful to farmers for a constant source of income besides their regular farm products. They do not required to expend extra for their feeding if the number of cattle are less. With slight extra care they can earn enough to meet their daily expenses. Cows, buffalo, all the milk giving animals are easy to care.

All over the world, when people get richer their life style change and they consume more animal protein, especially meat. We may add value by good genetics and know how in farm and feed management. There would be huge demand for poultry products and meat in coming years in India as per capita income of middle class people is gradually increasing and for that production of meat and meat products is required to be increased to meet the demand. Meat of goat, buffalo chicken are generally sold in India. Marketing of meat and meat products, chicken and poultry products such as eggs are the main challenges for the new farmers as there is no ready market in India. Recently there is huge demand of Chicken in Northern India. The initial problem faced by farmers is getting the special chicken feed for the different age groups. There is no well equipped dedicated slaughter house available in every city. New technology for animal slaughter is required so that all parts of animal are used properly without losing valuable protein. The idea should be to use innovated technology to optimize the profits in the chain.

Food prices have risen 6% in the last six months. But it is expected to rise further as expensive energy, squeezed supplies and volatile weather take a combined toll. The biggest factor pushing prices is the cost of producing and marketing crops. Several factors will make farming more expensive in the coming months. The first variable is weather. Preliminary forecasts by a few foreign and private Indian meteorologists say India could have a below-normal monsoon because a weather phenomenon called El Nino is warming the Pacific Ocean. El Nino usually affects monsoon winds headed for India. Forecasters say monsoon might arrive on time but could falter during August-September, especially in the north.

Abstract

Radon being the radioactive daughter product of Uranium; the interrelationship between U and Rn has been established in the present study. It is found that Radon coexist with Uranium in the region. A total of 61 samples were collected spatially from hand pumps and bore wells of the study area. Major ions such as Ca²⁺, Mg²⁺, Na⁺, K⁺, F^-, Cl^-, HCO^3-, NO^3-, H₄SiO₄,PO₄- and SO₄^2- and U, Rn were analysed. The lithological influence of U and Radon occurrence is also highlighted. Hard rocks especially Granites are the source for both U and Rn in the study area whereas the lack of correlation exist between U and Rn in sedimentary terrain can be attributed to difference in flow conditions and chemical properties of these elements. 

Key words: Radon, Uranium, Granite, Ground water, Source.
 

Abstract

Quality of water is affected by natural and man induced contamination to groundwater system. Area chosen for study has gained its own importance due to the location of two lignite mines and a Thermal power plant in operation. Extensive large scale pumping of water is done for lignite mining. The mine drainage and drainage from thermal power plant along with agricultural return flow from lignite charged waters increases the severity of problem. In order to achieve a panacea for the above-mentioned situation, the study has incorporated and integrated in all related factors to get a meaningful interpretation for groundwater quality and quantity management in and around Neyveli area. The frequent failure of monsoon has added to the existing problem of over exploitation. To attain a panacea for water chemistry groundwater samples were collected for four different seasons. Higher EC and TDS values are observed in Southeast and Southwest part of the study area. In Southwest monsoon and Summer seasons HCO₃Cl dominates the anions, with few representations for SO₄. In Northeast monsoon and Post monsoon season Na + K – Ca + Mg is the dominant. Thermodynamic, studies reveal that groundwater of the region are stable with Kaolinite stability field in all the silicate systems. Bicarbonates derived from silicate mineral weathering are noted in the NW, Northern and in the mining region. These regions are located in the NW and NE part of the study area. Comparison of water quality to standards shows that the water can be used for drinking and for irrigation purposes except in few locations.

Abstract

In semiarid climates, a significant component of recharge to basin aquifers occurs along the mountain front. In this scenario Mountain Front Recharge study has been carried along the foothills of Courtallam ,Tamil Nadu. A total of 53 groundwater samples were collected along the foothills and measured for major cations and anions using standard procedure. Saturation index (SI) of carbonate minerals like Aragonite,Magnesite, Calcite and Dolomite,LogpCO₂ and Ionic strength obtained from WATEQ4F output. pH plays a significant role in the saturation index of the minerals. Most of the Carbonate minerals shows undersaturation  with the pH range 7.5. Positive relationship between SI and HCO₃ is noticed. A sharp increase of pCO₂ values towards the foothills region suggests that the groundwater has been recharged by, acquiring longer flow path during its infiltration into deeper level near foot hill region. The SI of these carbonate minerals was spatially distributed to identify the areas of higher SI and also it is compared with the water level fluctuation to understand the recharge process along the foothill region as well as riparian zone.

Abstract

The geochemical signature and vulnerability of groundwater of the East Coastal aquifers of  India from Pondicherry to Nagapattinam were determined. The coastal aquifers are fragile and this situation becomes more intense in aquifer systems like that of the Pondicherry to Nagapattinam region. A total of 136 water samples were collected during pre and post monsoon of 2008 and 2009 respectively. Out of which 45 samples for each pre and post monsoon from shallow groundwater and 23 samples for each pre and post monsoon from deeper groundwater.. The samples collected were analysed for major, minor cations and anions. Selected samples were also analysed for stable isotopes (d¹⁸O and dD). The analysed samples were studied for; their utility for different purpose, the nature of the geochemical classification, their variations in ion ratios, extent of sea water intrusion and the percentage of mixing, The study reveals that chief mechanism controlling shallow groundwater is the salts precipitated in the pore spaces during the Pre monsoon were leached and dissolved during the subsequent monsoon apart from sea water intrusion. Southern part of the study area  is more vulnerable than the Northern part of the study area.

Abstract

A total of 30 groundwater samples were collected in four different seasons (Pre Monsoon, South West Monsoon, North East Monsoon and Post Monsoon) from the coastal aquifers of Kalpakkam region of Tamilnadu. The samples were collected covering the seasonal and lithological variations to infer the influence of natural geochemical processes and anthropogenic sources on the groundwater chemistry. The collected samples were analysed for the parameters like EC, pH and Major ions. The saturation index of silicates and carbonates shows that state of saturation to over saturation, but the sulphate minerals is dominantly under saturated. In the inverse modeling three models are obtained using PHREEQC and the error percentage is noted as 7.45%.

Abstract

Deduction of overindulgence fluoride (F)  from the water has been endeavor by numerous investigators by using different materials both natural and artificial. The objective of this paper was to attempt the fluoride removal by using the locally available natural materials such as red soil, untreated charcoal, local powdered brick, fly-ash from Neyveli (thermal power plant) and mineral serpentine were used, adopting column method. Maximum defluoridation occurs immediately after the experiment has started. The morality of fluoride removed per gram is more in red soil when compared to the other materials. Variation of fluoride removal with time was studied after the erection of the column /unit, the defluoridation setup was then connected to the public water supply from the overhead tank of 50,000L capacity. Higher F removal was noted when flow rate was lesser. An attempt on the regeneration of the fluoride adsorbed soil was also made.

Abstract

Coastal aquifers are the sources of freshwater which are being over extracted due to increase in population, agriculture and industrial activities. This over exploitation has resulted in decline in groundwater level and intrusion of sea water into the coastal aquifers making it unfit for human utilities. An attempt has been made in the coastal tracts of Pondicherry region using Electrical resistivity imaging. The survey has been attempted in six locations spread thought the study area and the interpretation has been attempted by RES2DINV software. The profile length attempted was between 150 to 300 m with electrode spacings between 5 to 10 m. The apparent resistivity ranges between 0.1 to 1183 & ohm. Sea water intrusion was prominent along the northern parts of the study area and lower resistivity isolated in kirumambakkam has been interpreted as salinity due to the presence of clay minerals. In nallavadu saline intrusion has been identified at shallow depth.
