Rice paddies are a primary grain production base in China and also a significant source of gaseous nitrogen emissions. Research on nitrogen emission reduction in paddy fields is crucial for ensuring national food security and mitigating nitrogen pollution. This study employed a randomized complete block split-plot design, with main plots subjected to three fertilizer treatments with the same total nitrogen, phosphorus and potassium: conventional fertilization (CK), controlled-release fertilizer (CRN), and urea supplemented with a nitrification inhibitor (DMPP), with same N, P, K total quantity. The subplots were planted with three rice varieties: Zhongzheyou 8, Yongyou 1540, and Zhehexiang 2. The objective was to investigate the interactive effects of rice variety and fertilizer management practices on gaseous nitrogen emissions in paddy fields and rice yields. The results demonstrated that the interaction between DMPP treatment and rice variety significantly reduced cumulative nitrous oxide (N₂O) emissions. Under the CRN treatment, plots planted with Yongyou 1540 exhibited the lowest N₂O emissions. Plots planted with Zhongzheyou 8 and Yongyou 1540, both amended with CRN, showed lower total ammonia (NH₃) volatilization, at 48.1 kg/ha and 57.9 kg/hm², respectively. Regarding total gaseous nitrogen emissions, the interaction modes involving Zhongzheyou 8 or Yongyou 1540 with CRN resulted in significantly lower cumulative emissions compared to other interaction modes. In terms of yield, the combination of planting Yongyou 1540 with CRN application achieved the highest grain yield. Consequently, considering both grain yield increase and gaseous nitrogen pollution control, cultivating Yongyou 1540 in combination with CRN application can achieve the dual objectives of high rice yield and reduced gaseous nitrogen emissions.
