The present investigation as carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2014-15.The experiment comprising of three fertigation frequency (Fertigaton at every 3^rd (F₁), 6^th (F₂) and 9^th (F₃) day) and four nitrogen levels (Nitrogen @ 90 (N₁), 120 (N₂), 150 (N₃) and 180 (N₄) kg/ha) was laid out in a Randomized Block Design with three replication. The removal of nitrogen, phosphorus and potassium, nitrogen use efficiency and water use efficiency were significantly higher when fertigation applied at every 3^rd day (F₁). However, black scurf incidence was maximum with F₃.Nitrogen levels exhibited significant difference for growth and yield. The maximum value for removal of nitrogen, phosphorus and potassium, nitrogen use efficiency and water use efficiency were maximum with the application of nitrogen @120 kg/ha (N₂). However, black scurf incidences were maximum with N₄.Interaction effect of fertigation frequency and nitrogen levels showed remarkable variation. The maximum nutrient use efficiency and water use efficiency with F₁N₂. When fertigation applied at every 3^rd day with the application of nitrogen @120 kg/ha was found significantly superior to all other treatments combination. https://www.biotech-asia.org/vol13no4/efficient-use-of-water-and-fertilizerthrough-drip-fertigation-in-potato-solanumtuberosuml-cv-kufribahar-in-haryana/ Drip irrigation; Fertigation frequency; Nitrogen; NUE; WUE
