Abstract: Potato is an essential food and economic crop that contributes significantly to national food security. As the issue of water scarcity in agriculture becomes increasingly prevalent, research into appropriate irrigation systems to accomplish water conservation, high quality, and stable potato yield has attracted widespread attention. The physiological characteristics, growth patterns, and water use efficiency of potatoes at various reproductive stages exhibit distinct responses to deficit irrigation. This paper specifically examines the impact of deficit irrigation on photosynthetic traits, water use efficiency, and potato yield. The findings indicate that severe water deficits hinder the accumulation of photosynthetic products and dry matter in potatoes, ultimately leading to a reduction in yield. In contrast, timely and adequate irrigation promotes optimal growth conditions.
