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. %U https://jci.ut.ac.ir/article_82142_3553ec2ef2cd94877cf17b2b7f32df97.pdf
