Research Progress on Effects of Water and Nitrogen Regulation on Yield and Quality of Potato

As the fourth most important food crop globally, potatoes play a crucial role in contributing to global food security. Enhancing both yield and quality is therefore of considerable importance. Among the many agronomic factors influencing potato development and productivity, water and nitrogen management has emerged as a central area of focus in recent research worldwide. This paper synthesizes recent advances related to water and nitrogen regulation in potato cultivation, particularly regarding their impacts on nitrogen accumulation, yield performance, quality attributes, and the efficiency of water and nitrogen utilization. Through a comprehensive evaluation of current findings, this study aims to offer a theoretical foundation for optimizing water and nitrogen use, thereby promoting simultaneous improvements in potato yield and quality.
