GERMINATION AND EARLY GROWTH RESPONSE OF GLYCINE MAX VARIETIES IN TEXTILE AND PAPER INDUSTRY EFFLUENTS

Present investigation was carried out to assay the effects of industrial effluents on different varieties of soybean. For that purpose Textile effluent and Paper & Board effluent were chosen. Concentrations used for both the effluents were 0, 10, 20, 40 & 60%. On the other hand 5 varieties of Glycine max viz., PSC-82, NARC-2, NARC-5, NARC-7 & William-82 were used. 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 improvement in seedling length was found in 60% of textile effluent (NARC-2, NARC-7 & Williams-82), and in paper & board effluent (NARC-2, NARC-5 & NARC-7). For others varieties, lower concentrations enhanced the growth. Number of leaves was unaffected and remained same in all concentrations of the two effluents. Overall seedling lengths of PSC-62, NARC-2 and NARC-5 were comparatively longer in paper and board effluent as compared to textile effluent but it was other way round for the varieties NARC-7 and Williams-82, while there was no set pattern for the weight parameters.
