Recent research has shown synergy between fungicide (F) and nitrogen (N) in winter wheat (Hooker et al, 2015). This trial investigates if any similar synergy exists in spring wheat. The data generated from this trial will be used to validate, and/or update, the Provincial (Ontario) nitrogen recommendations for spring wheat (Agronomy Guide, Publication 811). Depending on the findings of this study, this may mean differential N recommendations for spring wheat grown with and without fungicide. Maximum Economic Rate of Nitrogen (MER-N) will be determined, both with and without fungicide, from the N response curves generated from the data obtained.
