Abstract

The Iowa corn yield test is not a contest and should not be confused with the Iowa Master Corn Growers Contest. The Iowa Corn Yield Test is a controlled test where all planting, harvesting and computation of performance results is done by the Iowa Crop Improvement Association and Iowa Agricultural Experiment Station personnel. It has one purpose—to obtain unbiased information about the performance of many corn hybrids offered for sale by different growers and concerns. The 5-acre Master Corn Growers Contest, on the other hand, is a contest to see who can produce the most corn on a given area of land. In the Master Contest a comparison of corn hybrids is not involved since there is no check to show how a different hybrid would perform under the same conditions.
