- Intervention effect Omitting N reduced maize yield by 5–28% against the lower full NPK rate across sites.
- Intervention effect Omitting P reduced maize yield by 4–44% against the lower full NPK rate across sites.
- Intervention effect Omitting K caused 21% maize yield loss at sites 2 and 3.
- Association Higher maize yield was associated with increased NPK uptake.
- Association Higher maize yield was associated with increased NPK use efficiency.
- Intervention effect Higher NP levels produced the highest mean grain yields.
- Intervention effect NPK application produced the highest net economic returns.
- Intervention effect Higher NP levels produced the highest net economic returns.
- Recommendation The authors recommend revising blanket fertilizer recommendations.
- Method / resource QUEFTS predicted 6.3 t ha−1 mean maize grain yield against an actual 7.4 t ha−1.
- Method / resource QUEFTS validation had RMSE of 1.5 t ha−1.
- Method / resource QUEFTS validation had PBIAS of 6.9%.
- Recommendation The authors propose QUEFTS for site specific fertilizer recommendations.
