The genetic yield potential of soybeans in the Midwestern United States is estimated to be approximately 100 bushels per acre, based on results from small-plot studies. However, field and statewide average yields are much lower. Soybean yield is the result of complex interactions between genetics, management, environment, fertility, and stresses. Water stress is often viewed as the biggest underlying factor resulting in yield loss. However, other factors such as soybean cyst nematodes, Rhizoctonia root rot, and hail damage can also cause significant injury to soybean yields
