Lippia citriodora L., Verbenaceae family, is cultivated due to useful secondary metabolites like essential oil compound, which apply in the food, cosmetics industries. This plant is used as decreasing blood sugar, anti-blood releasing of nose and enteral. There are a lot previous studied which investigated essential oil compound in Lippia citriodora in greenhouse or field alone. Because L. citriodora were cultivated extensively in greenhouse and field in Yazd province. Knowing more about yield (morphological and essential content) in both conditions is very necessary. This study was designed with objective to evaluate the performance of L. citriodora for morphological and essential oil (yield and content) under different conditions of cultivation (greenhouse and field) in Yazd conditions. Our results showed Location exerted a highly significant influence (P<0.01) on all investigated traits. Year showed a highly significant influence (P < 0.01) on all the traits. Fresh leaf yield per plant, dry leaf yield per plant in L. citriodora is considered as economic traits. Location, year and interaction of Location × Year were significantly difference for these both parameters. GC-Mass chromatogram showed that the main compounds were D-limonene (7.85vs 6.68), Alpha-citral (6.57vs 5.52), Beta-Citral (5.68vs 4.65), spathulenol (4.58 vs 3.04), Caryophyllene oxide (6.54vs 4.96), in field and greenhouse respectively. As a results, cultivation of L. citriodora in greenhouse cause to increase plant biomass, while essential oil content were increased in field.
