The purpose of the Iowa Corn Yield Test is to find for each district and section of the state those strains of open-pollinated corn and hybrid combinations which produce the greatest yield, mature properly, possess resistance to lodging and have good quality or possess other characteristics which might make them desirable. Significant differences in these characteristics between different kinds of corn grown in adequately replicated tests may be attributed to differences inherent in the strains.
