Impact of Zinc Electroplating Industry Effluent Residue on Growth, Biochemical Characteristics and Yield of Cow Pea Vigna Unguiculata

Rajan, M. R, S. David Noel, R. Amarnath

Abstract :

The present study evaluates the impact of different quantities (0,250,500, 750 1000 and 1250 mg) of zinc electroplating industry effluent residue on growth, biochemical characteristics, yield of Cow pea Vigna un –guiculata. Growth characteristics such as shoot length, root length, total fresh weight, total dry weight, and vigour index and biochemical characteristics such as chlorophyll a, b, total chlorophyll, carotenoide content and yield were estimated after 60 days. Germination percentage of cow pea is 100 in all treatments. Growth, biochemical characteristics and yield of Cow pea Vigna unguiculata was higher in treatment 3 with 750 mg of zinc electroplating industry effluent residue
