Performance comparisons of early (1.0-1.8) and late (1.9-2.5) maturity soybeans in southeastern Minnesota are now available. Soybeans 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 26 early-maturity entries ranged from 59.9 to 73.6 bushels per acre and from 60.3 to 71.3 bu/a for the 26 late-maturity entries.
Tables 3 and 4 provide the yield for the late maturity entries at 13% moisture by entry and yield rank, respectively. Late maturity soybean yield average was 67.3 bu/a with a range of 71.3-60.3 bu/a.
The LSD found at the bottom of each table is the "least significant difference" or the minimum difference in yield we need to see before we can say with confidence that there is a true difference in yield between a pair of varieties. For more information about interpretation of the LSD, see the articles Field studies: What do you mean 5 bushels per acre is not significant? or How to do research on your farm.

Study details
The studies were conducted near Rochester, MN (Lawler site) on a Port Byron silt loam:- Planted May 15, 2019 with a 4-row John Deere planter equipped with cone units.
- Seeding rate: 165,000 seeds per acre at a depth of 1.5 inches.
- Row spacing: 30-inch rows.
- Plot size: 4 rows by 22 feet.
- Machine harvested center 2 rows of each plot on October 9, 2019.
2019 Soybean yield results
Tables 1 and 2 provide the yield for the early maturity entries at 13% moisture by entry and yield rank, respectively. Early maturity soybean yield average was 65.7 bu/a with a range of 73.6-59.9 bu/a.Tables 3 and 4 provide the yield for the late maturity entries at 13% moisture by entry and yield rank, respectively. Late maturity soybean yield average was 67.3 bu/a with a range of 71.3-60.3 bu/a.
