Water and nitrogen are the most important factors affecting yield and quality in potato management. Proper irrigation and nitrogen fertilizer management ensures water conservation and reduces nutrient loss. Nitrogen (N) is the most commonly deficient mineral nutrient in agricultural soils to increase potato production. Therefore, the split application of nitrogen fertilizers is important to prevent losses through leaching, evaporation, denitrification, weeding, erosion by running water, and precipitation. Determining the appropriate amounts of nitrogen and irrigation water to improve the efficiency of water and nitrogen use can minimize N losses, minimize costs and increase production profits. Potato is very sensitive to water stress due to its shallow root system and requirement to consume a plenty of water in all growing season. Therefore, regular irrigation of potato is important for obtaining the best tuber yield. This review has been made to identify and analyze in current research on N management practices and irrigation regimes to improve and maintain potato tuber yield. Variability of results from research studies show that determined precise results are not transferred from one place to another because potato varieties and cultivation conditions are not the same. In addition, it was determined that the responses of potato varieties to different nitrogen amounts varied from region to region. According to different irrigation regimes, it has been seen that the best result increasing yield in potato is obtained from applications when the plant is irrigated the most and field capacity is fully saturated. In addition, although the most appropriate nitrogen and irrigation interaction differ from region to region and depending on the variety, it has been determined that the most irrigation is applied and the nitrogen is obtained from application roughly 200 kg/ha.
