Abstract
Industrial development creates the disposal of industrial effluent has become the more ecological challenge. The physico chemical analysis of the tannery effluent showed high alkalinity, BOD, COD and more total dissolved salts. The effects of various concentrations ie control 10, 20, 30, 40, 50 and 100 per cent of tannery raw and BTE effluent were tested on seed germination and morphological parameters of Vigna radiata. Various morphological growth parameters such as shoot and root lengths, fresh and dry weights, vigour index, tolerance index and percentage of phytotoxicity were analysed. The pot culture experiment treatments T1, T2, T3,T4 and T5 were irrigated to crop plants. The morphometrical parameters of green gram were assessed at different sampling days (15, 30, 45 and 60 DAS).The root length and leaf area were increased at 10 per cent of both Raw Effluent (RE) Biologically Treated Effluent (BTE) and then decreased with an increase of effluent concentrations.
