Regional research trials
Variety trials, herbicide evaluations and other research is conducted each year. University of Minnesota researchers, scientists, specialists and Extension personnel are involved in the trials in several different locations throughout the state.

Herbicide evaluations
2020
Variety rotation as a strategy for managing soybean cyst nematode
A twelve-year field experiment at Waseca, Minnesota found a rotation of Peking with PI 88788 resistance is a good strategy for managing the soybean cyst nematode (SCN), and susceptible varieties and no-till may reduce pressure to select different SCN HG types.
