REPLANT DECISION MAKING - SOYBEANS

Published on Friday, August 5, 2022

When deciding whether or not to thicken up a stand with a 30 in. planter, this is an excellent study to reference when making that decision. In this study, a drilled stand of 66,000 seeds/A. was supplemented by adding three different rates with a planter (120,000, 80,000, and 40,000 seeds/A.). They were able to measure the contribution of the replanted plants by using black soybean seeds, which always produce black soybeans (recessive trait), and then sort the harvested soybeans with a color sorter. The data clearly indicates that supplementing stands with a 30 in. planter likely did as much damage during the planting operation as it contributed to additional yield.
