Abstract :

The present study deals with the impact of Dye industry effluent residue on growth, biochemical characteristics and yield of Lady’s Finger Abelmoschus esculentus grown for a period of 60 days. The Dye industry effluent was collected from Chinnalapatti, Dindigul District, Tamil Nadu, India. Physico – chemical characteristics such as pH, electrical conductivity, total solids, total dissolved solids, total suspended solids, hardness, sodium, potassium, calcium, magnesium, chloride, dissolved oxygen, Biological Oxygen Demand and copper were estimated. Different quantities of dye industry effluent residue such as 500, 1000, 1500, 2000 and 2500 mg were used for growth studies. Growth parameters such as seed germination shoot and root length, fresh and dry weight, biochemical characteristics such as chlorophyll a, b, total chlorophyll and carotenoide and yield performance such as number of fruits, weight and size were carried out on 20th, 40th and 60th day. Germination of Lady’s finger is higher (86%) in treatment 1 with 500 mg of dye industry effluent residue and lower in treatment 2 with 1000 mg of residue. Shoot length, fresh and dry weight; chlorophyll a, b and total chlorophyll were higher in treatment 1 and lower in treatment 5. Carotenoid content is higher in treatment 1 and lower in treatment 5. The yield performance is higher in treatment 5 with 2500 mg of dye industry effluent residue.
