2021 Performance comparisons of early and late maturity soybeans in SE MN available

Lisa Behnken, Research specialist - field trials

Performance comparisons of  early (1.0 to 1.8) and late (1.9 to 2.4) maturity soybeans in southeastern Minnesota are now available. Soybean evaluated in this trial were tolerant to one or more of the following herbicides: glyphosate, glufosinate, dicamba, 2,4-D, and/or a specific HPPD herbicide. Traits for each entry are included in tables 1-4. Yields for 22 early maturity entries ranged from 56.9 to 69.7 bushels per acre and from 58.1 to 71.6 bushels per acre for 19 late maturity entries.

The study was conducted near Rochester, Minnesota (Lawler site) on a Port Byron silt loam:
  • Planted - May 25, 2021 with a 4-row John Deere planter equipped with cone units
  • Seeding rate - 165,000 seeds per acre planted at a depth of 1.5 inches
  • Row spacing - 30-inch rows
  • Plot size - 4 rows by 22 feet
  • Herbicides - Warrant Ultra + Pursuit / Glyphosate + Select Max
  • Harvest - Machine harvested center two rows of each plot on October 18, 2021
