Other claims from this paper (8)
- Association Homogeneous zone significantly affected maize yield in Field 2.
- Intervention effect Nitrogen response was affected only by nitrogen rate.
- Intervention effect Simulated maize yield was significantly affected by nitrogen.
- Method / resource The model accounted for spatial variability, with an HZ effect and HZ-by-nitrogen interaction.
- Association The economic optimum nitrogen rate differed among homogeneous zones in both fields.
- Association Temporal variability of grain yield, nitrogen response and net revenue increased with nitrogen rate.
- Recommendation The authors propose zone-specific nitrogen rates to improve nitrogen use efficiency and grower profits and reduce environmental impacts.
- Recommendation The authors suggest selecting nitrogen rate by homogeneous zone to reduce environmental and economic risk.
