- Observation In the rainy year, maize grain yield declined relative to 2020.
- Observation In the rainy year, maize nitrogen partial factor productivity declined.
- Observation In the rainy year, maize agronomic nitrogen utilization efficiency declined.
- Intervention effect Nitrogen application increased maize dry matter accumulation relative to N0.
- Intervention effect Nitrogen application increased maize grain weight by 14.6–82.1 mg per grain over N0.
- Intervention effect Nitrogen application increased maximum grain filling rate by 0.2–3.4 mg per grain per day.
- Intervention effect Nitrogen application increased grain filling weight increment by 10.4–44.1 mg per grain.
