Plant Health (Growth Regulators, Biologicals, etc.), Medium Yield
This experimental field was in Buffalo County, South Dakota. Soybeans 24×728 variety was planted in 30-inch rows in strips on April 27, 2021. SoyfxTM was applied to the treated strips at 1 pt/acre on 6/18/2021. This was a microbial product that contained the following:
Bacillus magaterium 1.0 x 105 CFU/mL
Bacillus pumilus 1.0 x 102 CFU/mL
Soluble potash (K2O) 1%
The treatment effect was analyzed separately by yield zone, which was either low (<35 bu/ac), medium (35 to 55 bu/ac) or high (>55 bu/ac).
Strips treated with SoyfxTM applied yielded 4.6 bu/ac higher than those without the treatment. This difference, however, wasn’t significant at the 90% confidence interval.
