Maize, referred as Queen of cereals is the third most important cereal crop after rice and wheat in India. Maize serves as both human food as well as animal feed and for. Productivity of maize can be increased by proper nutrient management practices. Maize is a zinc responsive crop and found deficient in soils. Zinc as an essential micronutrient that has significant role in basic plant metabolic processes and enhances the growth, yield and quality of maize by stimulating chlorophyll production, photosynthetic activity, nutrient uptake and protein biosynthesis. The zinc application to maize crop either by seed treatment, soil application or by foliar spray by using inorganics have shown significant impact on growth, yield, nutrient uptake, quality and economics from investigations of eminent researchers with increasing trend in productivity. Application of zinc at 20-25 kg ha-1 to maize gave maximum grain yield (7500 kg ha-1) and benefit cost ratio ( 2.4 ) in maize.
