A Study of Regulated Deficit Irrigation on Farmland Soil Environment, Yield and Water Productivity of Potato

Year: 2025

Type: article

Abstract: This paper examines the impact of regulated deficit irrigation on the soil moisture and temperature environment of farmland, as well as its effects on the physiological characteristics, yield, and water productivity of potatoes at various growth stages. The aim is to determine the optimal control period and the appropriate degree of deficit irrigation for potatoes. In conclusion, while water stress may decrease photosynthetic rate, transpiration rate, stomatal conductance, and overall water consumption, it can also improve the soil's hydrothermal conditions. Mild regulated deficit irrigation during the seedling and tuber formation stages does not negatively affect potato yield. In fact, it can enhance both water productivity and irrigation water productivity.
