Abstract

In this study Sanganer town, Jaipur was selected as study area. The plants of Lycopersicon esculentum var.? K 21(Tomato) treated with 20 and 30% textile wastewater were analyzed for metal accumulation, growth and biochemical parameters at per, peak and post flowering stages. Findings of the study revealed that chlorophyll content was most severely affected with the increase in metal concentration. Total chlorophyll content showed a reduction of 72.44% while carbohydrate, protein and nitrogen content showed a reduction of 46.83, 71.65 and 71.65% respectively. With the increase in waste water treatment the root and shoot length, root and shoot dry weight and total dry weight were reduced to 50.55, 52.06, 69.93, 72.42, 72.10% respectively. After crop harvesting, the fruit samples of the plants treated with highest concentration of textile waste water contained 2.570 mg g^-1d.wt. of Zn, 0.800 mg g^-1d.wt. Cu, 1.520 mg g^-1d.wt. Cr and 2.010 mg g^-1d.wt. Pb.?
