Methodology
ESN was applied at 75 lbs N/acre on June 27 to a field planted in 30” rows at the V4 growth stage. The site received approx. 13.0 in. of rain and accumulated 1585 GDD’s from June 1 through August 31. This was approximately 3.9 in. more precip. and 83 less GDD’s than the 30 yr. avg.
Results
The yield response to ESN averaged over the two strips measured was 2 bu ac-1. Results from this study are provided in Table 1. ESN costs approximately $525 per ton. Applying this rate could cost close to $45/acre in product alone.
These results show that economical yield response may be predictable, which could warrant a precision application. Future studies are needed to confirm this concept and develop management zones for possible precision applications.
