How to use nitrogen fertilizer is crucial for farmers in boosting crop yield and fostering sustainable agricultural development. We hypothesized that replacing the (N) provided by mineral with manure would enhance soil water storage, increase efficiency (WUE), maintain maize yield, improve economic benefits. performed experiment 0% (CK), 25% (M25), 50% (M50), 75% (M75), 100% (M100) of N (225 kg ha–1) an equivalent amount from during 2016–2019. M25 M50 increased storage at 0–2 m depth after harvest, while significantly decreased evapotranspiration 5.27–22.14% compared CK. The replacement treatments WUE 6.58–13.62% 5.68–18.00%, respectively, fourth fertilization year. Meanwhile, net benefits were higher than CK year precipitation irrigation water. M75 8.47–35.51% had highest comprehensive evaluation score. Thus, study proposes a combination achieve high
