Lemongrass (Cymbopogon Citratus L.) is one of the most widely grown and essential oil bring plant. The field experiment was conducted at central rift valley of Ethiopia (Koka) to find the effects of Nitrogen (at 0, 30,60 and 90 kg ha-1) and Phosphorous (at 0,10, 20 and 30 kg ha-1) on lemongrass herbage yield, essential oil yield, and essential oil content. Application of nitrogen and phosphorous fertilizers were significantly increased crop growth characters such as number of tillers, number of leaf hill, herbage yield, essential oil yield. The results proved interaction effects of application fertilizer were gives a higher yield of lemongrass herbage yields, essential oil yields, number of tiller and leaf per hill compared to 0 kg ha-1 N and P (unfertile plot). The results showed maximum herbage yield (25.9 t ha-1) essential oil yields (155.5 kg ha-1), a number of tillers per hill (81) and a number of leaf per hill (352) were obtained from the application of 90 N + 20 P2O5 kg ha-1 fertilizers. Generally, the results clearly indicated that the application nitrogen and phosphorous fertilizers in appropriate quantity form can boost up the growth and oil yield of lemongrass.
