Description

The seventy-fourth year for the test was completed in 1993. For each of those 74 years Iowa State University has provided Iowa corn growers with performance evaluation data on varieties and hybrids of corn available for them to grow. Over the course of the past 74 years, the program has changed a lot. For a description of the early history of the Corn Yield Test see Chapter 8 in the book "The Iowa Crop Improvement Association" by JoeL. Robinson and Oliver A. Knott, Iowa Crop Improvement Association, Ames, IA 50011, 1963. Mention of other early historical events of the Iowa Corn Yield Test is also found in the book "The Hybrid CornMakers", the Golden Anniversary Edition: 1942-1992, by Richard Crabb, West Chicago Publishing Co., West Chicago, IL 60185, 1993. The main objective of the project, however, has not changed over the past 74 years: To provide Iowa corn growers with unbiased performance data about corn varieties and hybrids available for them to grow. I want to emphasize the word "unbiased." We do a lot of extra work to assure that all entries are treated exactly the same and later I'll mention how we do this. We could also add "release the data in a timely manner" to the objectives. In the early years of the program, data were not made available until mid-February. Today, the data are usually available on Exnet around the first of December.
