In the present investigation an attempt has been made to assess the effect of distillery effluent on seed germination and biochemical parameters of Dolichos lablab. The seeds were subjecting to different concentrations of distillery effluent viz., (5%, 10%, 15% and 20%). All the germination and morphological parameters viz., percentage of germination, root and shoot length, fresh and dry weight, vigour index, tolerance index and percent toxicity were found to be decreased with increasing the concentration of the effluent when compared to control. The chlorophyll and protein content also were found to be decreased as the concentration of the effluent increased when compared to control. The maximum value for germination and biochemical parameters were obtained in control sets were the minimum value were observed at 20% effluent concentration. These results showed that enlistment of seed reserve during germination is inhibited by effluent treatment.
