    The Iowa Crop Improvement Association (ICIA) have completed this year’s Iowa Crop Performance Tests (ICPT) and are now out with their full 2020 reports for both corn and soybeans.

    ICPT provide direct, unbiased comparisons among a large number of corn hybrids and soybean varieties, in many different environments. Data is posted online within 48 hours of harvest, giving you an early look at test results with full reports published after harvest is completed.

    The ICIA, in conjunction with Iowa State University, conducts the tests on ISU research farms and cooperating private farms across the state.

    You can find the full 2020 reports here:

    There are roughly 200 different varieties of corn and soybeans provided by more than 20 seed companies that are tested to determine yield potential.  Locations stretch across every region of the state, accounting for various soil compositions, weather conditions and production systems. Consistent planting methods for each site ensures the integrity of each experiment.

    Each seed entry is replicated four times in randomized four-row plots at consistent planting rates and row spacing. Multiple replications of the experiments conducted at multiple fields provide a wealth of information for making hybrid or variety selection decisions.

    “With three districts and five locations in each district we will produce yield data that is meaningful to you regardless of where you call home,” said ICPT Project Manager Graydon Marzen. “If farming is your passion use our comprehensive yield results to help make data driven decisions on what you and your family plant. We are Iowa’s official variety testing program professionally producing yield testing results for over 100 years!  If you have questions about our program or results please email gmarzen@iastate.edu or call 515-720-0391.”
