- 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 13.7%-33.6% relative to TT 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.
- Recommendation Vertically rotary sub-soiling tillage is helpful for increasing maize drought resistance and productivity without risking soil water balance.
