The 2019 County Standardized Trials data are now available. This year, 58 hybrids were evaluated with 49 test locations being harvested.  A great corn year brings the overall average across all locations and hybrids to 206 bu/ac.  The tables are separated into 3 maturity groups, early <114 day, medium 114-116 day, and full >116 day corn.  Hybrids are listed in descending order within each maturity across locations.  UT recommends selecting hybrids that are in the A group statistically. Hybrids with *’s next to their name, have been in the A group for consecutive years.  Two (**)  indicate this hybrid has been in the A group for 3 consecutive years.

A special thanks to those companies involved in these trials for sending a great lineup.  Thank you to all the county agents involved in getting these trials in and out.  Thank you especially to the producers who allow these trials to be placed in their fields to provide all of Tennessee with a non-bias look at head to head yield comparisons across the state.

Our county corn trial numbers are still rolling in, but results are up for the small plot trials performed at the University of Tennessee AgResearch and Education Center locations. Results can be found at search.utcrops.com/corn-grains as both web tables or as a downloadable excel file. These tables will be updated with county data as soon as that is available.

AgResearch and Education Center (REC) plots are 5 ft (2, 30 in rows) by 30 ft and are replicated three times per location. Total number of entries was on par with most years, totaling 89 corn hybrids, representing 14 company/brands. Continue reading →
