The objective of the present work was to observe the effects of the effluents on one of the crop plants. The physico-chemical parameters of the effluent sample show that the pollution level is high in the effluent which was collected from Okhla Industrial Area Phase-I, New Delhi. In this study we have found that, the growth of Solanum melongena was good at 25% concentration of the effluent for 15, 30,45 and 60 days in the soil without any treatment, soil with cow dung treatment and soil with the Neem treatment. In this study ETI (Effluent Tolerance Index) showing the continuous decrease with the increase in concentration of effluents reduces the growth of Solanum melongena. The study suggests that the effluent may be used for agricultural purposes after taking the suitable dilution of the effluents.
