The present investigation deals with the utilization of different concentration (control, 5, 10, 25, 50, 75 & 100 %) of sugarmill effluent on seed germination, growth and pigment contents changes of blackgram (Vigna mungo, var.co-5). The physico chemical properties of the effluent was brown in colour with acidic in nature. BOD and COD values in high and rich in suspended and dissolved solids. It also considerable quantity of nutrients also present. The results shows that the lower concentrations (5 and 10%) were increased the germination, seedlings length, fresh and dry weight and pigment content like chlorophyll ‘a’, chlorophyll ‘b’ and carotenoid. The above mentioned parameters were decreased with the increase of effluent concentrations (25-100%). However, the lower concentration may be used as substitu te for liquid fertilizer in crops.
