Cotton Yield Response to ESN
2013 study conducted by Dr. Hunter Frame, Virginia Tech, Suffolk, VA. 60lbs of nitrogen applied at sidedress to each treatment.

A Virginia study demonstrates how ESN can increase yields in dryland cotton production. ESN protects nitrogen (N) from loss inside its unique protective coating and supplies N to the crop when it is needed. The result is increased cotton yields and improved N-use efficiency.

Cotton plants need N throughout the growing season. Most N uptake by a cotton plant takes place in the period of about 40-80 days after planting and continues up to 140 days after planting. ESN may be used to meet this long season demand.

In this Virginia study, ESN applied to the surface of the soil at lay-by yielded higher than a blend of AMS and urea.
