 ABSTRACT

Maize or corn is the third most important cereal crop in India after rice and wheat. Maize is used in many ways for human food as well as animal feed. It is also used in some agro based industry. To increase total production of maize productivity can be increased by efficient nutrient management practices through zinc application. Zinc is such an essential nutrient required for maintenance of optimal health, DNA repair, enzyme activity, immune response and many other biological processes. Each increment of zinc application through soil application, seed treatment and foliar spray improves growth. The plant drymatter (DM) yields increases with a moderate Zn addition level. The Zn-based treatments increases grain yield indicates that there is much more benefit in grain quality than just yield after external Zn application. Addition of Zn results in increase in maize grain and stover Zn concentration. Maize with combined application of Zn as seed priming and foliar spray produced significantly more grain zinc content Total Zn uptake along with NPK also increases with Zn application through different sources of zinc fertilizer.
