EFFECT OF VEGETABLE OIL MILL EFFLUENTS ON SEED GERMINATION AND SEEDLING GROWTH OF GLYCINE MAX (L.)Regar Durgalal and Jaiswal PoonamAbstract Present study was carried out to assay the effects of vegetable oil mill effluents on soybean. For that purpose Soybean oil mill effluent and Mustard oil mill effluent were taken. Different concentrations (0% control, 20%, 40%, 60%, 80% and 100% OME) were used for both the effluents. Seeds of Glycine max (L) variety Pratap Soya 1 were used to test the effect of different concentration of effluents on seed germination and seedling growth. Physicochemical characteristics of these effluents revealed that both of them contained high amounts of sulphates, nitrates, calcium, various heavy metals etc., while DO was very low, which confirms their highly polluted conditions. Maximum seed germination percentage was found in control (0% OME) as well as in experimental set with 20% OME in both the treatments. Seed germination shows decreasing trend with further increase in OME concentration. Results show that lower concentrations enhanced the growth in early stages of development in Mustard OME but during later stages growth shows decreasing trend in both the treatments. |
