Evaluating Nitrogen Use Efficiency of Wheat.

Nitrogen recommendations for wheat are often based on inherent assumptions regarding nitrogen use efficiencies. Assessing whether or not expected N use efficiencies are actually achieved, however, needs further development and application. Furthermore, farmer capacity to evaluate site-specific wheat performance (e.g. yield, protein, nitrogen use efficiency) in the field is becoming technologically and logistically feasible. This development can empower farmers to assess their management practices and promote farm level innovation. We present field-based research that links N use efficiency, precision technologies and wheat performance goals. The developed framework is useful for research and farm production activities that evaluate wheat performance.
