Most agronomic studies have focused on increasing nitrogen use efficiency (NUE) through the management of nutrients in the soil (4Rs), but little is known about the effect of cropping systems on NUE. This study examines the differences in NUE among five popular spring wheat varieties as related to soil N fertility and two Montana cropping systems, crop–fallow and continuous cropping.
