Plant Health (Growth Regulators, Biologicals, etc.), Low Yield
This experimental field was in Buffalo County, South Dakota. Soybeans 16X628 variety was planted in 30-inch rows in strips on May 15, 2021. Vitazyme was applied to the treated strips during planting at 13 oz/acre in-furrow . This experiment had only replication for treatment at low yield zone. During the analysis, whole field was separated into different yield zones i.e., Low (<35 bu/ac), mid yield (35 to 55 bu/ac) and high yield (>55 bu/ac).
Overall, Vitazyme application at low yield zone reduced yield by 4.23 bu/ac (Figure 1 & Table 1). Due to insufficient number of replications, we were not able to perform statistical analysis. We have found increase in yield due to Vitazyme application at Mid yield zone of the field at various locations. Therefore, more research at multiple sites with more replications are required to better explain the contrast between two different treatments in different environmental condition.
