- Intervention effect RTN3 increased yield of NJ9108 by 9.64% relative to farmers’ fertilizer practices at the same nitrogen rate.
- Intervention effect RTN3 increased yield of NJ5718 by 10.18% relative to farmers’ fertilizer practices at the same nitrogen rate.
- Observation RTN3 had the highest nitrogen accumulation at heading stage, reported as 11.30 t ha−1 across 2018 and 2019.
- Intervention effect RTN3 had 8.1–21.28% higher N agronomic use efficiency than other fertilization modes at the same nitrogen rate.
- Intervention effect RTN3 had 8.51–41.76% higher N physiological efficiency than other fertilization modes.
- Intervention effect RTN3 had 0.28–14.52% higher N recovery efficiency than other fertilization modes.
- Intervention effect Reducing the nitrogen rate lowered dry matter accumulation and nitrogen accumulation.
- Intervention effect Reducing the nitrogen rate lowered nitrogen use efficiency.
- Recommendation The authors propose RNR1 for cost savings and increased resource use efficiency.
- Recommendation The authors recommend further application and investigation of RTN3 and RNR1 for grain yield and resource use efficiency.
