Recent interests in improving agricultural production while minimizing environmental footprints emphasized the need for research on management strategies that reduce nitrous oxide (N2O) emissions and increase nitrogen-use efficiency (NUE) of cropping systems. This study aimed to evaluate N2O emissions, annualized crop grain yield, emission factor, and yield-scaled- and NUE-scaled N2O emissions under continuous spring wheat (Triticum aestivum L.) (CW) and spring wheat–pea (Pisum sativum L.) (WP) rotations with four N fertilization rates (0, 50, 100, and 150 kg N ha−1). The N2O fluxes peaked immediately after N fertilization, intense precipitation, and snowmelt, which accounted for 75–85% of the total annual flux. Cumulative N2O flux usually increased with increased N fertilization rate in all crop rotations and years. Annualized crop yield and NUE were greater in WP than CW for 0 kg N ha−1 in all years, but the trend reversed with 100 kg N ha−1 in 2013 and 2015. Crop yield maximized at 100 kg N ha−1, but NUE declined linearly with increased N fertilization rate in all crop rotations and years. As N fertilization rate increased, N fertilizer-scaled N2O flux decreased, but NUE-scaled N2O flux increased non-linearly in all years, regardless of crop rotations. The yield-scaled N2O flux decreased from 0 to 50 kg N ha−1 and then increased with increased N fertilization rate. Because of non-significant difference of N2O fluxes between 50 and 100 kg N ha−1, but increased crop yield, N2O emissions can be minimized while dryland crop yields and NUE can be optimized with 100 kg N ha−1, regardless of crop rotations.
