The cultivation of winter wheat using conventional high-yielding methods often requires large amounts of fertilizer and water to promote individual plant growth. To address the challenge of scarce water supply, increasing water use efficiency in agriculture has been proposed as a means of maintaining or increasing food production while reducing irrigation water usage. The North China Plain, a critical grain-producing region in China, has been actively developing water-efficient wheat in recent years due to severe groundwater shortages. While numerous studies have been conducted in this region, the results have been inconsistent, highlighting the need for further investigation. For example, some studies have indicated that a sowing density of approximately 525 to 600 plants m-2 and an irrigation amount of 75 mm at pre-sowing and jointing stages is the best cultivation method for water conservation and high yield of winter wheat. Conversely, deficit irrigation strategies have also been increasingly adopted in the development of water conservation. Despite these efforts, there is still significant interannual yield variability under long-term conditions, making it necessary to consider the effect of diverse water management strategies on crop yield. In this context, this study aims to investigate the impact of different water management strategies on winter wheat yield, while considering interannual yield variability, in the North China Plain.
