Seeding Rate/ Varieties/ Row Spacing, High Yield
Pioneer P25A12X and P24A99X soybeans were planted in strips on May 15, 2018 at 140,000 seeds/acre in 30 inch rows.
In this trial, Pioneer P25A12X averaged 2.00 bu/ac more than Pioneer P24A99X. This increase in yield was not significantly different. A yield increase of 2.39 bu/ac would be required for there to be significant differences at the 90% confidence level.
