Methodology
This trial was conducted at top hill of the field. Soybeans were planted on June 15, 2019 at 160,000 seeds/acre in 30-inch rows. Nitrogen and sulfur fertilizer were applied at the rate of 30 lb/ac and 15 lb/ac respectively at R3 growth stage. Fertilizer source for nitrogen was polymer coated urea whereas for sulfur it was ammonium sulfate. Both fertilizer treated and untreated treatment had four replications. Plot size for this experiment was 10 feet wide and 30 feet long. For the data analysis each fertilizer treated replication were compared with untreated replications.
Results
Overall, at top hill of the field, nitrogen+sulfur fertilizer increased yields by 6.36 bu/ac, however it was not statistically significant (Table 1). All Reps (1,2 and 3) except 4, saw an increase in yield whereas Rep 4 had reduced yield. Additional trials with more replications should be completed to identify efficacy of treatment over multiple years.
