The ameliorating effect of vermicompost and cow dung compost on growth and biochemical characteristics of Solanum melongena treated with paint industrial effluent was evaluated in this study. The color and odor of the effluent samples, physical and chemical parameters like pH, EC, TDS, TS, EC and heavy metals were analyzed. The effluent contained sulphates, chlorides, phosphates, dissolved solids and other pollutants in higher amounts. The effect of effluent with water, vermicompost and cow dung were studied on shoot length, root length, leaf area, fresh weight, dry weight and biochemical parameters like Chlorophyll a, Chlorophyll b, Total Chlorophyll and Carotenoids of S. melongena. It was noted that the length of the root and shoot, fresh and dry weight of the plant was considerably decreased with increase in concentration of the effluent. There was a gradual increase in all the parameters except the leaf area with increase in effluent concentration with vermicompost and cow dung. There was no change in the chlorophyll content on 80% effluent with vermicompost when compared to the control, whereas reduction in the carotenoids content was noted in 80% effluent with vermicompost.
