The experiment was conducted at Wondo genet agricultural research center, southern Ethiopia from 2014 to 2016 cropping season to determine the optimum harvesting age of lemongrass varieties for maximize essential oil yield. The experimental design was RCBD in factorial arrangement with three replications. The treatments were two lemongrass varieties (Lomisar-UA and Lomisar-Java) and five harvesting age (45, 60, 75, 90 and 105) days after planting. The study showed that variety had a very highly significant (p≤0.001) influence on numbers of tillers/plant, longest leaf length, fresh herbage yield kg/plot, fresh herbage yield kg/ha, dry herbage yield kg/ha and essential oil yield kg/ha and significant (p≤0.05) influence on essential oil content. Harvesting age had a very highly significant (p≤0.001) influence on fresh herbage yield kg/plot, fresh herbage yield kg/ha, dry herbage yield kg/ha and essential oil yield; highly significant (p≤0.01) influence on longest leaf length, numbers of leaves/plant and significant (p≤0.05) influence on number of tillers/plant. Fresh biomass g/plant, fresh herbage yield kg/plot, fresh herbage yield kg/ha, dry herbage yield kg/plat, dry herbage yield kg/ha and essential oil yield kg/ha were a very highly significantly (p≤0.001) influenced by the interactions of variety and harvesting age. The minimum essential oil yield for both lemongrass varieties were recorded from harvesting age of 45 days after planting. Whereas, the maximum essential oil yield (59.03 kg/ha) and (101.13 kg/ha) ware recorded from 105 days after planting for Lomisar-UA and Lomisar-Java varieties respectively.
