Plant Health (Growth Regulators, Biologicals, etc.), High Yield
Soybeans were planted in 30-inch rows at 130k seeds/ac in Minnehaha Co. on May 18, 2022. A humic and fulvic (HF) blend was applied to the crop at R1 on 7/11/22 at 0.78125 lb/acre, which was diluted in 25 gal water/ac. Soybeans were harvested on October 10, 2022, and yield analysis was conducted on the from the middle harvest pass from each treated strip. This field only had a high yield zone (>55 bu/ac).
The HF foliar application had no significant effect on soybean yields (90% confidence interval) since the difference between treatments was less than 2.0 bu/ac (Figure 1 & Table 1). Future research with this product in different yield environments would be beneficial.
