In this Indiana study, ESN increased yields in wheat production. ESN applied at F3 increased yields compared to all other treatments. When ESN blended with urea was applied at the same time, yields were higher than a corresponding application of urea without ESN, and similar to all other urea treatments. The ESN application also increased test weights compared to all other treatments.
