Usingof mycorrhizal biofertilizers and right varieties can spur the production of patchouli on Andisol soil. Besides that, it can also increase root colonization by mycorrhizal andP2O5uptake which is needed by patchouli plants so as to produce a high oil content.This study used a Randomized Block Design(RBD) Factorialwith three replications. The first factor observed was mycorrhizal biofertilizer of various types of strains, namely mycorrhizal biological fertilizer of genus Glomus mosseae, mycorrhizal biofertilizer of genus Gigasporasp. and mixture of Glomus mosseaeand Gigasporasp. While the second factor was the use of varieties with the Tapak Tuan and Lhokseumawe varieties levels. The results showed that the bestmycorrhizal biofertilizers on production, root colonization, P2O5uptake and oil content were found in the mixture ofmycorrhizal genus (Glomus mosseae+ Gigasporasp.). The best variety for production, root colonization, P2O5uptake and oil content was found in Tapak Tuan variety
