Thank you to all those who participated in County Standardized Trials this year.  Our corn data is in and reported below.

For more information or assistance with the CST program, please contact your local County Extension office.

Early Maturity <113 day RM

Medium Maturity 114-116 day RM

Full Maturity >116 day RM

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.
