Plant Health (Growth Regulators, Biologicals, etc.), High Yield
Mustang 22X228 soybeans were planted on May 23, 2018 at 150,000 seeds/acre in 15 inch rows. Primo foliar inoculant was applied at 1 pt/ac in 20 gpa water near the R1 growth stage.
Primo foliar inoculant had little effect on soybean yield (0.35 bu/ac). This change in yield was not significant. A yield difference of 2.24 would be required for there to be significant differences at the 90% confidence level. The small increase in yield could have been a result of the inoculant that was on the seed at planting. Mixed results with Primo foliar inoculant have been noticed in the past.
Funding for this research project was provided by the South Dakota Soybean Research and Promotion Council. The authors would also like to thank the soybean producers who participated in this project.
