Methodology

Methodology
This trial was conducted at footslope of the field. Soybeans were planted on May 15, 2020 at 160,000 seeds/acre in 22-inch rows. Nitrogen and sulfur fertilizer were applied at the rate of 41 lb/ac and 20.43 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 footslope of the field, nitrogen+sulfur fertilizer increased yields by 0.43 bu/ac, however it was not statistically significant (Table 1). Out of four, Reps 2, 3 and 4 saw an increase in yield whereas Rep 1 had reduced yield. Additional trials with more replications should be completed to identify efficacy of treatment over multiple years.
