Most Ontario growers choose soybean varieties that will reach maturity based on the projected crop heat units (CHU) for their particular area. This practice is usually combined with planting soybeans in mid-May. One management strategy that consistently leads to higher yields is early planting. Another strategy may be to plant late maturing varieties for a given area. With the introduction of CruiserMaxx seed treatment higher plant populations can often be achieved under more stressful conditions making it possible to plant earlier. This project was conducted to determine if an early planting strategy along with the use of late maturing varieties can increase yield potential in Ontario.
