Zinc fertilizers and pesticides are widely used to increase crop production in agricultural practice, which over the years led to elevated levels of zinc in the soil. Zinc is a micronutrient involved in wide variety of physiological processes and represented in all the six enzyme classes. Seeds of Sorghum bicolor (L.) Moench cultivar CSH 14 are selected for the experiment and the plants were grown in pots for fifty days. Plants were treated with five different concentrations of zinc solution viz: 1.5, 3.5, 5.5, 7.5 and 9.5mM taken as zinc sulphate. Sampling was done at different stages of plant growth (Viz., 15, 30 and 50 days) for measuring various morphological and growth parameters like root and shoot length, fresh weight, dry weight, phytotoxicity, tolerance index and relative growth index. Significant reduction in different growth parameters was observed in Sorghum plants at all stages of plant growth with increase in zinc treatment.
