Influence of four concentrations (5, 10,25,50 mg/kg soil) of three heavy metals viz. zinc, nickel and cadmium on the total chlorophyll content, total nitrogen content and grain yield of wheat (Triticum aestivum cv. 2425) was recorded. The effect of heavy metals on these parameters varied with the level of concentration. Zinc and nickel stimulate the total chlorophyll content, total nitrogen content and grain yield at lower concentration (5, 10 mg/kg soil), however, with a further increase in zinc and nickel concentration, decrease in all the parameters was observed. Zinc was found to be more beneficial than nickel at lower concentration. Cadmium led to continuous decrease in all parameters with an increasing concentration.
