Impact of Zinc electroplating industry effluent residue on growth, biochemical characteristics and yield of Tomato Lycopersicom esculentum

M. R. Rajan, M. Periyasamy

Abstract :

The present study evaluates the impact of different quantities (500, 1000, 1500, 2000 and 2500 mg) of electroplating industry effluent residue on growth, biochemical characteristics, yield performance Tomato Lycopersicon esculentum. 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, carotenoides, total soluble sugar and protein content were decreased with increasing quantities of electroplating industry effluent residue. However, anthocyanin, free amino acids, L–proline and leaf nitrate content were increased with increasing quantities of electroplating industry effluent residue. Yield performance such as number of fruits/plant, length of fruit and weight of fruits/plant was reduced with increasing quantities of electroplating industry effluent residue.
