Table 6. 2021 MG-3 Yield Data by REC Location (1yr, 2yr, 3yr)

Table 6. Mean† yields across and by location of 7 Maturity Group III (3.0 – 3.9) soybean varieties evaluated in replicated small plot trials at eight AgResearch and Education Center locations in Tennessee during 2021. Analysis included variety performance over 1 yr (2021) period. 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.
