In order to investigate the effect of foliar application of microelements on the quantitative and qualitative traits of spring corn hybrids, this factorial experiment was conducted in the form of a randomized complete block design with three replications on a farm located in Weiss County in the 2016-17 crop year. Experimental treatments include foliar application of microelements in five levels of pure water foliar application (control), foliar application of iron, foliar application of Cu, foliar application of manganese and foliar application of iron, Cu and manganese as the first factor and two hybrids SC704 and single cross Mobin were performed as the second factor. The results show that the foliar interaction of micro and hybrid elements on grain number per row, grain yield, biological yield, protein yield, ear length and leaf area index were significant at the level of 1% probability and on 1000-grain weight, harvest index and protein percentage at the level of 5% probability. The highest grain yield (9700 kg/ha), biological yield (22030 kg/ha) and protein yield (979 kg/ha) were obtained from foliar application of Cu, Iron and Manganese in hybrid compared to the treatment without foliar application (Control (SC704) showed an increase of 35%, 26% and 46%, respectively. According to the results, it seems that foliar application of micro elements could increase the quantitative and qualitative performance of Mobin hybrid and KSC704 had lower fertilizer capability.
