The University of Illinois Variety Testing program, dating back to 1934, conducts annual crop performance tests to provide farmers, extension personnel, and private seed companies with agronomic information on hybrids and varieties of the major Illinois field crops. The trials are professionally managed and conducted in a research-based manner to minimize variability and ensure the integrity of the results. This level of expertise and professionalism make performance reports issued by this program the premier source of objective third-party information on current varieties.
