Drug flower yield in 2016 was 72.95 kg da(-1) while it was 93.92 kg da(-1) in 2017. The effect of irrigation on yield was not statistically significant, though the yield in 50% irrigation treatment was relatively higher compared to the other two treatments. The results of essential oil content and yield in 2017 were statistically significant and the highest essential oil content (5.5%) and yield (5.17 kg ha(-1)) were obtained from I100 irrigation treatment. Although the results of essential oil ratio and yield in 2016 were not statistically significant, similar to 2017, the highest essential oil ratio and yield (4.75%, 3.27 kg ha(-1)) were obtained from I100 irrigation treatment. The results indicated that irrigation had a significant positive effect on the essential oil content and yield of lavender. The ratio of linalyl acetate, which is the most important component of essential oil, ranged between 18.62 and 22.54% in 2016 and 2017. The results showed that lavender (Lavandula intermedia) can be grown well under semi-arid ecological conditions, however, the continuation of studies on lavender would be useful in making more accurate decisions. Scientific studies focusing on the effects of different irrigation treatments on characteristics of lavender are rare, thus this research is one of the first studies published on the subject. The results demonstrated the importance of irrigation in lavender (Lavandula intermedia) cultivation for essential oil production. The results revealed that irrigation in lavender cultivation has no significant effect on flower yield, but full irrigation (I100) is important to obtain higher essential oil yield.eninfo:eu-repo/semantics/closedAccessLavender (Lavandula intermedia)Restricted irrigationEssential oil ratioQuality of essential oilArticle29317031712Q4WOS:000517349200051
