Preparing for Plant 21 (PFP21): Soybean Planting Date
Using the optimal soybean planting date is critical to maximize yield for our full season soybeans. Earlier planting dates typically result in more main stem nodes; more nodes result in more flowers and pods and subsequently higher yields. This national publication on soybean planting dates thoroughly explains the benefits of earlier soybean planting. There is much energy across the United States on planting soybeans earlier than historical for the associated yield benefits. In a recent analysis of 877 North Carolina Soybean Yield Contest entries, one of the strongest predictors of high soybean yield was the use of planting dates earlier than mid-May.
