Objective(s):

Manitoba Agriculture nitrogen rate guidelines for corn were developed before 1990 and are out-of-date for current yield levels. Recently North Dakota State University (NDSU) has released N rate guidelines for corn and a number of in-crop scouting measures can be used to assess sufficiency and need for more N. The following study was initiated with the objective to evaluate a number of N decision guides for suitability in fertilizing corn in Manitoba.
