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 16 early maturity entries ranged from 56.9 to 69.7 bushels per acre and from 56.2 to 70.4 bushels per acre for 16 late maturity entries.
The study was conducted near Rochester, Minnesota (Lawler site) on a Port Byron silt loam:
- Planted - May 31, 2020 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
- Insecticide - Sefina applied to control soybean aphids on August 14, 2020
- Harvest - Machine harvested center two rows of each plot on October 14, 2020
