Abstract
Maize (Zea mays L.) is high nutrient demanding crop but sensitive to zinc (Zn) deficiency in soil. Application of Zn fertilizers could be a viable option to fulfill the crop demand for Zn and also to increase its contents in grains. A field experiment was conducted to evaluate the effect of supra-optimal rates of Zn application on maize cultivars. A selected maize hybrid (FHY421) and a synthetic variety (Golden) were grown at four different rates of Zn application along with recommended doses of nitrogen, phosphorus and potassium. Cobs were harvested; grains were separated and analyzed for their Zn content. Response of genotype varied to different Zn application rates. Maximum grain yield and Zn uptake in maize hybrid (FHY-421) was noted at 18 kg Zn ha -1 . However synthetic variety (Golden) exhibited maximum grain yield and Zn uptake when Zn was applied @ 9 kg ha -1 . Maize response curve showed that for optimum grain yield, Zn concentration in hybrid was found 28.2
