In order to investigate the effect of nitrogen, phosphorus, and potassium elements on fatty acid profiles, oil percentage, grain yield, and flax seed oil, Lirina cultivar, a factorial experiment has been conducted during 2019, based on a randomized complete block design with three replications in Hashtgerd research farm, Alborz Province. It has employed a factorial arrangement in a randomized complete block design with three replications with the factors involving three levels of nitrogen fertilizers (N1=30, N2=60, and N3=90 Kgha-1, three levels of phosphorus fertilizers (P1=40, P2=80, and P3=120 Kg.ha-1), and three levels of potassium fertilizers (K1=40, K2=80, and K3=120 Kg.ha-1). Result show that the highest amount of linolenic acid (43.99%), linoleic acid (17.68%), and palmitic acid (6.02%) have occurred in 30 kg. ha-1 nitrogen and 40 kg.ha-1 phosphorus. The highest amount of oleic acid (27.49%) and stearic acid (5.25%) belong to 30 kg.ha-1 phosphorus. Based on the results, the highest amount of grain yield (2384 kg.ha-1) and oil yield (939 kg.ha-1) are recorded in 90 and 120 kg.ha-1 nitrogen and phosphorus, respectively. Therefore, according to the results, different levels of fertilizer on percentage of oil has had no significant effect.
