Methodology

Methods and Agronomic Information

Three strips of ESN® controlled-release polymer coated urea were applied as a surface broadcast at 75 lbs N ac-1 on June 24 when the crop was at V3.  The varieties, AG2835 (Strip 1) and AG2933 (Strips 2 and 3) were planted in 15” rows on May 19.  The seed was treated with IntegoTM (insecticide + fungicide) and Optimize® (rhizobia inoculant + LCO molecule). The field received approx. 16.1 in. of rain from June 1 through August 31.  Yield differences within each treatment strip (Figure 1) were calculated by subtracting untreated yield from treated yield, where untreated yield was estimated from data surrounding both sides of the treatment strip.

Results

Results

Overall, there was no significant yield response to ESN® (Table 2).  However, Strip 2 yielded 1.7 bu ac-1 greater than the surrounding untreated crop.   This strip ran through the highest-yielding part of the field.
