Synopsis Application of 5 pounds of Zn per acre broadcast and plowed under before planting increased early growth and grain yield. Other methods of application were less effective. Greater rates of application increased Zn concentration in young and nearly mature corn. Small amounts of N banded with ZnSO 4 enhanced the effectiveness of ZnSO 4 . Yields of corn grain were related to Zn concentration of the index leaf.
