    The present research work has been carried out to understand the effect of different concentrations of TANFAC effluent on seed germination and seedling growth of five varieties of black gram (Vigna mungo (L.) Hepper). The Increasing pace of industrialization in public and private sectors along with urbanization, population explosion and green revolution are reflected in varying degree of pollution of air, water, and soil. The TANFAC effluent is having a higher amount of organic and inorganic element. The Physico-chemical analysis showed that it was acidic in nature. It was rich in total suspended and dissolved solids with large amount of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). The effluents severally affect crop plants and soil properties when used for irrigation. The growth parameters such as germination percentage root length shoot length, number of lateral roots, fresh weight and dry weight were taken on 10th day. All the parameters were found to increase at 10% effluent concentration and it decrease from 25% effluent concentration onwards. Among black gram, variety V-2 was tolerant to TANFAC effluent when compared to other varieties

    Wastewater discharged by the industries is one of the major causes of environmental pollution, particularly in the developing countries. Present study was conducted in influence of TANFAC effluent (0, 10, 25, 50, 75 and 100%) on groundnut varieties (Arachis hypogaea L.) var. TMV-7, TMV-2, TMV-10 and TMV-13). The growth parameters such as seedling vigour, vigour index, tolerance index and percentage of phytotoxicity were measured on 10th day seedlings. The morphological and biochemical parameters such as chlorophyll, carotenoid, sugar and starch contents decreased with the increase of effluent concentrations except 10% effluent concentration. Among the four varieties studies TMV-7 performed better under TANFAC factory effluent treatment and it proved to be tolerant when compared to the remaining varieties

                The present investigation has been carried out to assess the effect of B &C effluent on morphological, biochemical and mineral content of groundnut seedlings. The physico-chemical analysis of the effluent revealed that the B&C effluent was alkaline in nature and it was rich in suspended and dissolved solids. Germination studies were conducted with various concentration of effluent. The morphological growth parameters (seed germination percentage, seedling growth, fresh weight and dry weight of seedling) and biochemical aspects (Chlorophyll a, b and total chlorophyll, carotenoid, sugar, protein, aminoacid and phenolic contents) showed the increased trend at 10% concentrations of effluent. However, the increased concentrations of effluent reduced the above-mentioned parameters. Among the mineral contents estimated, the phosphorus and potassium showed the same trend. But the nitrogen content showed the increasing trend with the increase of effluent concentrations

    Effect of briquetting and carbonisation plant effluent on seed germination of five varieties of groundnut (Arachis hypogaea L.)

                         The study deals with pollution by Briquetting and Carbonization plant effluent and its effect on five varieties of groundnut to evaluate its irrigation potential.  The effluent is brownish black in colour. It contains higher amount of total nitrogen, metallic and non-metallic ions, sulphates, sodium, chloride, calcium and magnesium.  The impact of various concentrations (10, 25, 50, 75 and 100 per cent) of this effluent on the seedling growth of five varieties of groundnut (Arachis hypogaea L.) was studied under laboratory conditions.  Germination percentage, seedling growth, fresh weight and dry weight of groundnut seedlings exhibited a gradual increase upto 10 per cent and decrease at higher concentrations.  The variety VRI-4 showed the better growth performance than the other varieties studied under effluent treatment
