Field experiment was conducted at Wondo Genet Agricultural Research Center and Koka substation in 2013/2014 and 2014/2015 cropping season in order to identify optimum nitrogen and phosphorus fertilizer rate for some selected agronomic characteristics, essential oil yield and oil content of artemisia. Four nitrogen levels (0, 46, 92 and 138 kg N ha^-1) and four phosphorus levels (0, 10, 20 and 30 kg P ha^-1) would be laid out in factorial RCBD with three replications. At koka condition, results revealed that plant height, leaf dry weight and essential oil content were significantly affected by separate effect of nitrogen and phosphorus fertilizer. The interaction of 46 kg N ha^-1 and 10 kg P ha ^-1 gave significantly higher above ground biomass, leaf fresh weight and stem fresh weight. Similarly, the maximum essential oil yield was obtained at the interaction of 92 kg N ha^-1 and control of P though statistically at par with 46 kg N ha^-1 and 10 kg P ha^-1. At Wondo Genet, all the parameters didn’t show any significant variation by the application of N and P and its interaction except leaf and stem fresh weight which is at par with the soil analysis result of the center. Thus at Wondo Genet production of artemisia without nitrogen and phosphorus fertilizer is economically visible. For Koka area and other similar soil type and agro ecologies of Ethiopia, N and P fertilizers at the rate of 46 kg N ha^-1 and 10 kg P ha^-1 could be recommended.
