- Intervention effect Biochar doses and irrigation methods increased maize growth and yield characteristics.
- Intervention effect Biochar doses and irrigation methods increased irrigation water use efficiency (IWUE).
- Intervention effect Biochar doses and irrigation methods increased soil properties.
- Intervention effect NB 1 increased maize yield by 4.96%–6.10% under BI and DI relative to NB 0.
- Intervention effect NB 2 increased maize yield by 8.36%–9.85% under BI and DI relative to NB 0.
- Intervention effect NB 3 increased maize yield by 9.65%–11.41% under BI and DI relative to NB 0.
- Intervention effect Non-biochar treatment had lower IWUE and FNUE than biochar plus N fertilizer under BI and DI.
- Observation IWUE with NB 2 and NB 3 under BI method was 3.36 to 3.43 kg kg −1.
- Observation IWUE with NB 2 and NB 3 under DI was 5.70 to 5.94 kg kg −1.
- Intervention effect Medium and high biochar doses increased maize FNUE.
- Mechanism Biochar effects were more obvious under DI than BI, attributed to higher rhizosphere soil water and N.
- Intervention effect Biochar improved soil water content and N concentration at 0–40 cm.
- Intervention effect Biochar decreased soil water content and N concentration below 60 cm.
- Observation Under BI, soil N concentrations were higher at 60–100 cm than in top and middle layers.
- Intervention effect Biochar increased soil organic matter and aggregate stability.
- Intervention effect Biochar maintained soil pH.
- Intervention effect NB 0 increased soil organic matter by 11.11%–14.60%.
- Intervention effect NB 2 increased soil organic matter by 14.29%–19.42%.
- Intervention effect NB 3 increased soil organic matter by 21.98%–23.78%.
