2019 Hybrid Corn Performance Trials

The accuracy of moisture and test weight measurements decrease as moisture content increases. This also affects the accuracy of yield determination. Results for hybrids with moisture contents over 30% should be interpreted with much caution.

It is important to note the LSD printed at the bottom of each trial. The LSD shows how much two hybrids must differ to be considered different. For example, if the LSD of a trial is 10, hybrids with yield indexes of 110 and 99 are different while hybrids with indexes of 110 and 101 are not.
