Areas of Interest
A large part of my research is directed toward understanding the needs of the vegetable processing industry in our region. Minnesota grows more acres of peas and sweet corn for processing (canning and freezing) than any other state, centered in southeastern MN. Our processing pea variety trial is the largest in the country. We have studied various aspects of sweet corn production, including response to hail damage, and collaborative work on nutrient management, use of cover crops, and emerging diseases in sweet corn.
