- Intervention effect Vertically rotary sub-soiling tillage increased soil water storage in 0-40 cm at sowing by 7.7, 8.6 and 6.6 mm relative to SS, TT and ZT.
- Intervention effect Vertically rotary sub-soiling tillage increased soil water storage in 0-100 cm by 18.2, 22.8 and 20.2 mm relative to SS, TT and ZT.
- Intervention effect Vertically rotary sub-soiling tillage increased aboveground biomass by 14.7%-18.3% relative to SS.
- Intervention effect Vertically rotary sub-soiling tillage increased aboveground biomass by 12.7%-18.8% relative to TT.
- Intervention effect Vertically rotary sub-soiling tillage increased aboveground biomass by 22.8%-29.1% relative to ZT.
- Intervention effect Vertically rotary sub-soiling tillage increased maize grain yield by 12.0%-13.0% relative to SS in 2016 and 2017.
- Intervention effect Vertically rotary sub-soiling tillage increased maize grain yield by 24.0%-47.4% relative to ZT in 2016 and 2017.
- Intervention effect Vertically rotary sub-soiling tillage resulted in higher leaf area index and SPAD value in maize.
- Intervention effect Vertically rotary sub-soiling tillage significantly improved maize water consumption in the pre-flowering period of the drought year and the post-flowering period of the normal year.
- Intervention effect Vertically rotary sub-soiling tillage decreased soil water storage in 0-300 cm by 11.4, 14.8 and 20.5 mm relative to SS, TT and ZT, with no significant difference among methods.
- Recommendation Vertically rotary sub-soiling tillage is helpful for increasing maize drought resistance and productivity without risking soil water balance.
