Abstract Northeast China (NEC) has recently become one of the largest commercial rice production regions in China. However, the increased production combined with increasingly frequent climate oscillations is severe competing for fresh water with the non-agricultural sectors in this region and is threatening national food security. In this study, the ORYZA (v3) crop model was used to estimate the rice yields and water applications under three management regimes, continuous flooded irrigation (CF), alternate wetting and drying (AWD), and rain-fed (RF), in the full nutrient supply and biotic-stress-free conditions in NEC from 1961 to 2016. The predicted average rice yields in these three production regimes were 12.7, 12.7 and 10.6 t ha−1. El Nino events reduced yields by 2.5% and 2.4% (P
