Purslane (Portulaca oleracea L.) is globally known for its α-linolenic acid (ω3). To investigate the combined effect of nitrogen and mycorrhiza under water deficit stress on the agronomic traits of purslane, a factorial split experiment was conducted based on a randomized complete block design with three replications in a semi-arid region of Iran in 2015 and 2016. The main plots were the factorial combination of two irrigation conditions (non-stressed control and stressed condition: irrigation at 70 % and 50 % of field capacity (FC), respectively) and two treatments, namely control and inoculation with arbuscular mycorrhiza fungi (AMF, Rhizophagus irregularis). The subplots were comprised of unfertilized control, 100 % farmyard manure (8.5 Mg FYM ha⁻¹, sheep manure (50 %) and chicken manure (50 %)), 100 % N (120 kg urea ha⁻¹), 75 % FYM and 25 % urea, 50 % FYM and 50 % urea, and 25 % FYM and 75 % urea. In the first and second years, the drought stress reduced AMF colonization (by 30.3 and 15.3 %), leaf phosphorous content (by 5.8 and 7.7 %) and grain yield (by 22.6 and 21.1 %) of purslane while leaf ω3 increased (34.6 and 34.1 %). The AMF increased the phosphorous uptake, grain yield, leaf essential oil, leaf ω3, and soil CEC. While reducing soil pH, application of nitrogen fertilizers enhanced soil organic carbon and leaf ω3. It can be stipulated that a mixed nutrition system increases the quantitative and qualitative traits in the purslane vegetative organs, reduces the use of agricultural inputs, and enhances the health of edible vegetative of purslane and soil chemical properties.

马齿ane（马齿ula）以其α-亚麻酸（ω3）而闻名。为了研究缺水胁迫下氮和菌根对马齿sl农艺性状的综合影响，基于随机完整区组设计进行了因子分解实验，该区组在2015年和2016年于伊朗的半干旱地区进行了三次重复。主要地块是两种灌溉条件（无压力控制和压力条件：分别以田间持水量（FC）的70％和50％灌溉）和两种处理方式的因子组合，即丛枝菌根真菌（AMF，不规则根瘤菌）。子图由未施肥的对照，100％的农家粪肥（8.5 Mg FYM ha ^-1）组成，绵羊粪便（50％）和鸡粪（50％）），100％氮（120千克尿素ha ^-1），75％FYM和25％尿素，50％FYM和50％尿素以及25％FYM和75％尿素。在第一年和第二年，干旱胁迫降低了马齿A的AMF定殖（分别降低了30.3％和15.3％），叶片磷含量（分别降低了5.8％和7.7％）和谷物产量（分别降低了22.6％和21.1％），而叶片ω3则提高了（34.6％和7％）。 34.1％）。AMF增加了磷的吸收，谷物产量，叶片精油，叶片ω3和土壤CEC。在降低土壤pH值的同时，施用氮肥可增强土壤有机碳和叶片ω3。可以规定，混合营养系统可以增加马齿sl营养器官的数量和质量特征，减少农业投入物的使用，并增强马齿edible食用营养素的健康和土壤化学性质。
