Winter wheat is a major crop in many regions, but its cultivation often requires large amounts of fertilizer and water to promote growth, leading to concerns over water scarcity. To address this challenge, increasing water use efficiency has been proposed. The North China Plain, a crucial grain-producing region in China, has made significant efforts to develop water-efficient wheat in recent years due to severe groundwater shortages. However, the results of numerous studies conducted in this region have been inconsistent, highlighting the need for further investigation.

Deficit irrigation strategies have been increasingly adopted in the development of water conservation. However, the effect of diverse water management on winter wheat yield, especially the interannual yield variability under long-term conditions, remains unclear. Furthermore, winter wheat cultivation is facing the dual challenge of water conservation and adapting to the increasing effects of climate change. The negative impact of climate change on global wheat production cannot be ignored, as previous studies have suggested that it could potentially reduce production by 30% by mid-century. Simulation studies and field observations have identified temperature variations and dry and hot winds as critical factors affecting winter wheat yields.

Therefore, there is a need for more research based on field trial observations to understand how diverse water management combined with weather conditions affect yield variation in winter wheat. This study aims to contribute to this research by investigating the impact of different irrigation amounts on winter wheat yield and interannual yield variability in the North China Plain over a three-year period.
