Table A-4. Mean† yield and agronomic traits of 7 Maturity Group III (3.0 – 3.9) soybean varieties evaluated in small plot replicated trials without irrigation at the Highland Rim AgResearch and Education Center in Springfield, Tennessee during 2021. All MG-3 varieties evaluated this year were new; therefore, 2 yr and 3 yr analysis are not presented.

† Varieties that have any MS letter in common are not significantly different at the 5% level of probability. Values highlighted in light orange are above average for a given trait, MS letters highlighted in dark orange are in the “A group”, indicating no statistical difference from the top-performing variety, for a given trait.
* Asterisks after a name indicate the number of preceding consecutive years in the top-performing “A” group.
‡ For a full description of abbreviated biotech traits, see table 31.
§ All yields are adjusted to 13% moisture.
‖ Lodging was evaluated on a a scale of 1 (no lodging) to 5 (complete lodging).
