This study was initiated in 2003 in response to a push by one of the grain buying companies to produce more durum wheat for export from Arizona. The export market required a minimum of 13% protein and other quality constraints. A nitrogen timing regime was established by the University to provide the crop with this nutrient according to its physiological development. This study had four nitrogen application treatments addressing different ways to provide the crop with its nitrogen needs. This second year of the study showed statistically different yields from the treatments applied and different inferences from the first year of the study. An economic analysis is included to show the profitability of nitrogen applications for this year and an economic summary for the last four years of nitrogen studies on durum wheat.
