Row spacing vital for June planting


Crops that are up and growing around the county are looking pretty good except for some fields where water has drowned out corn in some low wet spots from all the rain we have had. The rainfall has varied widely around the county the last few weeks.

All this wet weather prevented soybean planting in many areas of the county. Late planting reduces the cultural practice options for row spacing, seeding rate, and relative maturity.

Laura Lindsey, OSU Extension Specialist say that the row spacing for June planting should be no greater than 7.5-inch if possible. Row width should be narrow enough for the soybean canopy to completely cover the inter-row 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.

“Higher seeding rates are recommended for June plantings,” said Lindsey. Data from previously conducted seeding rate trials, suggest seeding rates between 200,000-225,000 seeds/acre when planting the first half of June.

For June planting dates, plant the latest maturing variety that will reach physiological maturity before the first killing frost. Lindsey says that this is to allow the plants to grow vegetatively as long as possible to produce nodes where pods can form before vegetative growth is slowed due to flowering and pod formation.

The recommended relative maturity ranges for our area are: June 1 – 15 3.4 – 4.0; June 15 – 30 3.3 – 3.7; July 1 – 10 3.2 – 3.5.
