- Observation Rain fed wheat had the lowest flag leaf chlorophyll concentration.
- Intervention effect Micro sprinkler irrigation enhanced catalase and peroxidase activity.
- Intervention effect Micro sprinkler irrigation reduced malondialdehyde content.
- Intervention effect Micro sprinkler irrigation promoted dry matter remobilization and production after anthesis.
- Intervention effect Micro sprinkler irrigation increased the contribution of dry matter to grain yield.
- Intervention effect Micro sprinkler irrigation boosted root growth.
- Intervention effect Micro sprinkler irrigation enhanced root activity during grain filling.
- Intervention effect Water use efficiency did not significantly differ between micro sprinkler and rain fed irrigation in 2021–2022.
- Intervention effect Rain fed water use efficiency was significantly lower than micro sprinkler in 2022–2023.
- Intervention effect Micro sprinkler increased water use efficiency over conventional irrigation by 15.1% in the first year.
