Soybean and late planting. There is a reason why the old adage is “August and sept make beans”. Weather conditions have a large impact on yield potential, with timely rainfalls throughout pod-fill the most important factor. Unlike corn, which requires the accummulation of heat to grow and develop, Dr. Naeve says that, “a soybean crop is pushed to maturity.” In years like 2022 in which soybean is planted late, the period during which vegetative growth occurs gets shortened considerably. Consequently, fewer leaves are added to plants and rows may never close, reducing the overall photosynthetic capacity of the crop. With fewer leaves, less energy gets stored in them to be remobilized later on to form seeds during reproductive growth.
