Department of Plant, Soil and Microbial Sciences Variety Trials

Hybrids are entered into zones based upon growing degree days and then grouped into Early and Late trials based upon relative maturities. There are 4 zones which grain hybrids may be placed into: Zone 1 – southern; Zone 2 – south central; Zone 3 – north central; Zone 4 – northern. There are 3 zones which silage hybrids may be placed into: Zone 1 – southern; Zone 2/3 – central; Zone 4 – northern. Within each zone, the hybrid is placed into a trial at 3 different locations: eastern, central, and western. In 2022, a total of 204 hybrids from 15 brand names were entered into the Michigan Corn Performance Trials. These hybrids make up the 230 grain and/or silage entries, which translates into 2,760 separate plots planted across Michigan in 2022. The Michigan Corn Hybrids Compared report summarizes the results from these trials.
