Abstract

To evaluate effect of NITROGEN and ZINC fertilizers on leaf ZINC and chlorophyll contents, grain yield and chemical composition of two maize hybrids, KSC704 and KSC540, a field experiment was carried out at the experimental farm of Shiraz University, Bajgah, Shiraz, in 2007. Factorial arrangements in randomized complete block design with three replications were used. Three levels of NITROGEN, as Urea, including, 120, 260 and 400 kgha-1, and three levels of ZINC, as ZINC sulphate, including, 0, 15 and 30 kgha-1, in factorial arrangments were assigned to main plots, and two maize hybrids, KSC704 and KSC540 were raindomized in sub-plots. Results showed that the highest grain yield was obtained from combination of 260 kgha-1 Urea and 30 kgha-1 ZINC sulphate. NITROGEN had significant (P<0.05) on leaf chlorophyll content measured by SPAD. The highest SPAD value belonged to combination of 260 kgha-1 Urea and 15 kgha-1 ZINC sulphate. Interaction of NITROGEN × ZINC was significant (P<0.05) on leaf and grain ZINC contents. Increasing ZINC increased NITROGEN absorption. It was concluded that application of appropriate combination of NITROGEN and ZINC would improve the grain quality and yield of maize under similar conditions.
