Abstract
Zinc an essential micronutrient, can be a notorious pollutant when in excess. It can interfere with plant metabolism, physiology and uptake of other mineral nutrients leading to serious effects on plants. A soil experiment was carried out in Sorghum, which is one of the major crop of arid and semi-arid regions of the world and an excellent material for abiotic stress studies. Sorghum plants were raised in pots for 50 days and were treated with various concentration of zinc given as milli molar solution (viz; 1.5, 3.5, 5.5, 7.5, 9.5 mM). In the present experiment soil applied zinc caused a linear increase in the tissue zinc content. The investigation revealed that excess zinc interferes with the absorption and utilization of micro (Fe, Cu and Mn) and macro (Ca and Mg) nutrients. Fe and Mn absorption was hampered at elevated levels. Ca and Mg content decreased with increase in soil applied zinc in the roots and shoots of Sorghum bicolor plants.
