- Intervention effect Irrigation and nitrogen application significantly affected wheat yield, resource efficiency, soil nitrate and leaching.
- Intervention effect Irrigation increased wheat yield by 14.88%–15.01% in 2017–2018.
- Intervention effect Irrigation increased wheat yield by 4.11–4.16 times in 2018–2019.
- Intervention effect W1 and W2 wheat yields did not differ significantly.
- Intervention effect Under W1, N150 gave the highest yield in 2017–2018.
- Intervention effect Under W1, N225 gave the highest yield in 2018–2019.
- Intervention effect N150 had higher nitrogen use efficiency than N225.
- Intervention effect N150 reduced soil nitrate leaching by 15.87% compared with N225 in 2017–2018.
- Intervention effect N150 reduced soil nitrate leaching by 10.20% compared with N225 in 2018–2019.
- Recommendation The authors recommend N150 with W1 for efficient water and nitrogen use and reduced nitrate leaching risk.
