Abstract
This study was conducted to determine corn response to three foliar-applied zinc sources. The study was conducted on dryland corn in Manhattan, KS, during the 2014 growing season. Yields were low as a result of very low precipitation during pollination and grain fill. There was no yield response to foliar-applied Zn; however, grain analysis show significant increases in grain Zn concentration from foliar-applied Zn. Foliarapplied Zn products are effective for increasing Zn uptake in corn. Additional studies need to be conducted to determine the yield response.
