Abstract
This study was initiated 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. No significant differences were seen in yields but slight differences in percent protein were observed. An economic analysis is included to show the profitability of nitrogen applications.
