Abstract :

The present study deals with the field level study on the impact of different quantities of electroplating industry effluent residue(250, 500, 750, 1000 and 1250mg) on growth, biochemical characteristics and yield of Brinjal Solanum melongena. The growth characteristics of Brinjal such as seed germination percentage, shoot and root length, total fresh and dry weight, leaf area index and vigour index were higher in T3 with 750 mg and lower in T5 with 1250 mg of zinc electroplating industry effluent residue on 90th day. The chlorophyll a, b, total chlorophyll, carotenoid and total soluble protein content of Brinjal was higher in T3 and lower in T5. The total sugar of Brinjal was higher in T2 and lower in T5. The anthocyanin, free amino acids, L– proline and leaf nitrate of Brinjal was higher in T5 and lower in T1. The length, weight and number of fruits of Brinjal were higher in T3 and lower in T5.
