Abstract

The Iowa Corn Yield Test attempts to provide comparable performance records on a relatively large number of hybrid combinations. Some of these on which information is presented are well established strains of known performance while others are new and relatively unknown to most Iowa farmers. Data are presented on each hybrid for yield, stand, moisture, root and stalk lodging, ear height and dropped ears. A performance score has been calculated for use in evaluating the relative agronomic -value o f the hybrids tested. It is believed that the information presented should afford a reliable estimate on the relative performance of a number of hybrids when grown in different areas of the state.
