Effects of tannery effluent on tomato plants its growth and biochemical characteristics.

Present study deals with the impact of different dilutions of tannery effluents on tomato seed germination with its growth and biochemical characteristics grown for a period of 90 days. Tomato plant grown with different effluent concentrations i.e, 0%, 20%, 40%, 60%,80% shows effects on plant growth parameters and biochemical parameters such as; seed germination percentage, shoot and root length, number of flowers and fruits and chloropHyll. The result clearly shows that the concentrations of effluents directly affect on the growth and biochemical constituents. The heavy metal accumulation found at higher level in root when compared with control. Both chromium (cr) and cadmium (cd), found to the maximum of allowable limit approved by WHO/FAO. Accumulation of heavy metals creates chronic health problems to human and cattle through food chain in long run.
