Reduced irrigation and nitrogen coupled with no-tillage and plastic mulching increase wheat yield in maize-wheat rotation in an arid region

Irrigation, nitrogen (N) fertilization, and tillage practices for spring wheat following plastic-mulched maize were studied to provide a basis for optimizing production technology to achieve high wheat yield in arid irrigated regions. No-tillage, plastic mulching, water-nitrogen interactions, and crop rotation are the important valuable strategies for improving grain yield (GY) in arid regions, but there is lack of theoretical basis on whether...
