    According to USDA-NASS, 66% of soybean acreage was planted in the USA by May 21, 2023. In Ohio, that number is similar, with 63% planted, and it is expected that the acreage planted will increase by the end of May due to dry planting conditions. However, planting will continue into June, and farmers may want to adjust their management practices to maximize soybean yield.

    Persistent wet weather is likely to push soybean planting into late May-early June in many areas of the state. Late planting reduces the cultural practice options for row spacing, seeding rate, and relative maturity.

Row width should be narrow enough for the soybean canopy to completely cover the interrow space by the time the soybeans begin to flower. The later in the growing season soybeans are planted, the greater the yield increase due to narrow rows.
