- Observation The estimated sugarcane yield gap was 55 Mg ha-1.
- Intervention effect Increased nitrogen fertiliser rate reduced the simulated yield gap by 30 Mg ha−1.
- Intervention effect Liming reduced the simulated yield gap by 25 Mg ha−1.
- Intervention effect Improved weed control reduced the simulated yield gap by 5–9 Mg ha−1.
- Intervention effect Replacing uncropped fallow with legume crops reduced the simulated yield gap by 2–3 Mg ha−1.
- Intervention effect Changing crop cycle duration produced no simulated yield gap gain.
- Intervention effect Retaining crop residues worsened the simulated yield gap by −2 Mg ha−1.
- Observation Yield benefit from conservation practices was similar across projected warmer and wetter or drier, and hotter and wetter climates.
- Intervention effect Liming gave one of the greatest projected yield benefits under a hotter and drier climate.
- Intervention effect Retaining crop residues gave one of the greatest projected yield benefits under a hotter and drier climate.
- Method / resource Daily weather data availability limited the modelling study.
