Methodology

Methods and Agronomic Information

Pioneer 90Y01 was no-tilled in 15 in. rows on May 13. Seed was treated with a fungicide, insecticide, and inoculant. Three strips of urea were applied on April 17, 2015. The field received approx. 9.0 in. of rain from June 1 through August 31.

Results

Results

On average, the treated strips yielded no differently than the estimated yield of those same strips without urea (Table 2). This estimate was calculated from data surrounding both sides of each strip. However, in areas where yields were often >60 bu ac-1, urea application before planting may have been beneficial. Even though it’s a more-costly product, an ESN® application on June 5, 2015 at V1 in the same field showed more potential for yield gain than urea application before planting.
