Zusammenfassung: | Clarifying the effect of intercropped green manure on the yield sustainability of maize under different irrigation levels plays a crucial role in the development of a water-saving and efficiency-oriented maize and leguminous green manure intercropping system. Field experiments were conducted from 2018 to 2022 using a split-plot experimental design, including two planting patterns: maize and green manure intercropping(M/V) and sole maize cropping(SM). Three irrigation levels were implemented:local conventional irrigation(I3: 4000 m3 hm–2), 15% reduction in irrigation(I2: 3400 m~3 hm–2), and 30% reduction in irrigation(I1:2800 m~3 hm–2). The effects of intercropped green manure on maize yield, yield components, relative multi-crop resistance index,yield sustainability index, key soil nutrient indicators, and economic benefits under different irrigation levels were investigated.The results indicated that intercropped green manure increased the number of maize kernels and thousand-kernel weight when subjected to |
