Potato (Solanum tuberosum L.) is highly sensitive to water stress, especially during critical growth stages such as tuber initiation and bulking. In Western Romania, increasing climatic variability, uneven rainfall distribution, and frequent drought periods during the growing season significantly impact both yield and tuber quality, making irrigation a key factor in sustainable production. This study evaluates the necessity of irrigation by examining potato water requirements in relation to regional climatic conditions, including temperature patterns, evapotranspiration, and precipitation dynamics. It also considers soil properties such as texture, structure, and water-holding capacity, which influence water availability and irrigation efficiency. In addition, irrigation water quality parameters, including salinity and pH, are analyzed due to their effects on soil condition, nutrient uptake, and crop performance. The results indicate that water deficits during critical phenological stages lead to reduced yields and compromised quality. Modern irrigation systems, such as sprinkler and drip methods, along with monitoring tools like soil moisture sensors, can significantly improve water use efficiency and crop response. Overall, irrigation is not merely supplementary but essential for achieving stable and high-quality potato production under current climatic conditions. Proper management of both soil and water resources is crucial for ensuring sustainability and resilience in Western Romania.
