With early cereal harvests over the past few years, and excellent late season growing conditions, some Ontario soybean producers have started to consider the possibility of growing soybeans after cereals as a double crop. There has been relatively little research conducted in Ontario to determine best management practices for double cropped soybeans. Dry conditions during mid-summer seeding can be a challenge in plant establishment but the biggest difficultly to double cropping soybeans is the risk of an early fall frost, which, if temperatures fall low enough will cause the soybean plant to shut down. If this frost occurs before seeds have been formed in the pods, there is nothing to harvest.
This project was designed to create recommendations for double cropping soybeans after cereals in Ontario.
