The University of Kentucky corn and soybean variety trial information is now available online. You can access the information through the QR Code in this article. The data was collected from seven corn locations and six soybean locations across the major growing areas of Kentucky.

A wet spring led to delayed planting in some trials, so pay close attention to planting dates and all the agronomic information. Remember, the multi-location state summary data is the best resource for making variety selection decisions. Growers should only use single-location data in conjunction with the state summary data to identify varieties that performed well both across the state and at their regional location.

For Corn, you will find good yields across all locations, except Fayette County. This was due to the planting date and then the hot, dry weather in that area in late summer. This led to a higher CV. The coefficient of variation (CV) is a calculated value that helps indicate unexplained variation in these studies. A smaller CV indicates less unexplained variation and more precise results. Field variability is usually amplified under less ideal/stressful environments.

For soybean, yields across trial locations were dramatically different based on precipitation levels at each site. CV values were acceptable to good at all locations, except the Warren County site, where drought stress fostered highly variable results (which was not included in the state summary).

For more information on all these tests, or to contact Bill Bruening or Cam Kenimer, please visit the website via the QR Code. We’d like to thank the Kentucky Corn Promotion Council and the Kentucky Soybean Promotion Board for their support and all others who helped make another successful year in variety testing!
