520 |a The 2015-2020 dietary guidelines for Americans advise substituting total unsaturated fatty acids (∑UFA) for total saturated fatty acids (∑SFA). Thus, field experiments were carried out to verify the influence of irrigation regime (well-irrigated and water deficit) and fertilizers (chemical and biological) on the ratio of ∑UFA to ∑SFA of evening primrose seed oil. Therefore, two experiments were conducted at the experimental stations (arid and semi-arid) of Iran in 2014 and 2015. Experiments were conducted in a split factorial layout within a randomized complete block design with three replications. Water deficit significantly reduced UFA (omega 3, 6, 7 and 9), ∑UFA and ratio of ∑UFA to ∑SFA (especially in the arid region), but it increased SFA and ∑SFA (especially in the arid region). In fact, fatty acid quality (increased ratio of ∑UFA to ∑SFA) of evening primrose seed oil was significantly increased in well-irrigated compared to water deficit stress (especially in the semi-arid region). Bio-fertilizers (Azospirillum lipoferum and Glomus mosseae) and chemical fertilizers (urea + triple superphosphate) increased the ratio of ∑UFA to ∑SFA of evening primrose seed oil (especially in the semi-arid region), but fatty acid quality of evening primrose oil was significantly increased in bio-fertilizers compared to the chemical fertilizers (especially in the arid region)
