► Breeding over 75 years has increased the nitrogen use efficiency of spring barley. ► The greater efficiency is the result of an increase in N uptake and utilization efficiencies. ► Improved utilization efficiency was more consistent across site-years than uptake efficiency. ► High uptake efficienc...
