2023 County Standardized Trials-Corn

Author:  Comments Off on 2023 County Standardized Trials-Corn

39 Corn Hybrids were evaluated in the 2023 CST program.  With the weather we had this summer, our yields are very strong with an overall average across all hybrids and locations over 210 bu/ac. With the many locations/replications in these trials, we can look at performance across many soil types and weather/climate conditions that you can use to help select high yielding, consistent hybrids to bring to your farm.  Contact your local county agent for more details or if you need a print out of this data.

These CST plots are large strip trials located ‘on-farm’ with a minimum of 300 feet in length.  Inputs and management decisions are on a by location basis and determined by the cooperating producers.  Three relative maturity groups divide the trials, Early Corn will be 113 day and earlier, Medium Corn will be 114-116 day, and Full Corn is 117 day plus.  Thank you to everyone involved in the CST program for your support and contributions: County Agents, UT Extension/Research, Growers, Industry, Retail.

Below are the results for our 3 RM groups.  Click on the table to open a PDF of these tables.  These results can also be accessed on

Early Corn <114 day
