Omex treatment hastened maturity over the bare seed check by 2–3 days
Yield was higher than in the untreated check (40 bu/ac) in the treatment with Primer Soybean® (45 bu/ac); First 30 Days® (46 bu/ac); Final 30 Days® (47 bu/ac)
Plants were taller in the plots treated with Omex allowing more pods, thus the yield advantage
