Soybean planting has been delayed by the frequent and heavy rain events occurring this spring. As a result, many soybean fields will be planted in June and producers need to implement specific management practices to maximize the yield potential of late-planted soybeans. Michigan State University Extension recommendations for late-planted soybeans are summarized in this article.
Plant as early as soil conditions permit. Yield losses due to delayed planting increase from 0.4 bushels per acre per day until June 1 to 1 bushel per acre per day on July 1. Also, remember that soybean maturity is delayed by one day for every three to four days that planting is delayed, increasing your risk of frost or freeze injury in the fall.
