Methodology

Methods and Agronomic Information

Pioneer 90Y01 was planted in 15 in. rows on May 13. Seed was treated with a fungicide, insecticide, and inoculant. ESN® controlled-release polymer coated urea was applied to the three treatment strips (Figure 1) at 75 lbs N ac-1 on June 5, 2015 at V3. The field received approx. 9.0 in. of rain from June 1 through August 31.

Results

Results

On average, the treated strips yielded 1.6 bu ac-1 higher than the estimated yield of those same strips without ESN® (Table 2). This estimate was calculated from data surrounding both sides of each strip. Segments of these strips appeared to have yield responses much greater than the average, showing potential for precision application, provided that responsive areas can be identified. An application on July 17, 2015 at R2 in the same field showed less potential than this V1 application.
