The University of Missouri Variety Testing Program’s motto is “We test the best.” This year seed companies entered some of their best corn and soybean hybrids in the MU variety testing program. The program used the most current scientific principles and procedures to compare hybrids in unbiased trials across Missouri.

Plots were located in multiple locations around the state including farmers’ fields and the University of Missouri agricultural experiment stations. The results include both irrigated and non-irrigated trials for corn and both Group 3 and Group 4 maturity ratings for soybeans. Plots were replicated three times in each location and randomly planted across the field. These sites represent a wide range of soil types and weather conditions.

Corn was planted in 30-inch rows at 30,000 kernels per acre in the non-irrigated trials and 38,000kernels per acre in the irrigated trials. The final yield was corrected to 15.5% moisture, but moisture at the time of harvest is also reported. As part of the trial, varieties were given a lodging rating just prior to harvest.

Soybeans were planted in 30-inch rows at a population of 160,000 seeds per acre. Lodging and height were also determined prior to harvest. The yield was correct to 13% moisture. The yield of non-irrigated corn in the North Missouri trials ranged from 206 bushels per acre to 252 bushels per acre. Yield of group three soybeans in North Missouri ranged from 51 to 64 bushels per acre and group four soybeans ranged from 55 to 62 bushels per acre.

Yield is not the only factor to consider when selecting a hybrid. Standability in soybean and stalk strength in corn, maturity, as well as insect and disease resistance are other important factors to take into consideration. The 2019 results are available online at
