Abstract Water shortage is a known limiting factor in sustainable wheat production in the North China Plain (NCP). Conservation tillage has the potential to maximize soil water efficiency, and also influence crop growth. The distribution of crop roots plays a vital role in determining water consumption and yield production. A 10-year field experiment was established to study the relationship between soil physicochemical properties and root distribution characteristics and determine grain yield, as well as water use efficiency (WUE) of winter wheat in response to tillage. Three representative tillage practices, no-till (NT), conventional tillage (CT), and rotary tillage (RT) were used. The results indicated that RT increased the spatial and temporal root distribution, enhanced photosynthetic activities at the flowering stage, and achieved higher average grain yield by 12.0 % and 6.7 % from 2008 to 2019 as compared with NT and CT, respectively (P
