Potato (Solanum tuberosum L.) is a plant prefetch queue of five seasonal vegetables that are much in demand in Indonesia. Potato needs tend to increase every year in line with population growth and development of the food processing industry are made from raw potatoes. In general, potato production in Indonesia is still relatively low and still do to meet their import requirements. But the government has always sought to boost the national potato production. One of the efforts to improve potato production with the use of Plant Growth Promoting Rhizobacteria (PGPR) and fungi Mycorrhizal Fungi (AMF). The use of microorganisms PGPR and Mycorrhizae naturally associated with plant roots and have the ability to improve plant growth. The purpose of this study is to obtain the best interaction between species rhizobacteria and mycorrhiza on the growth of potato plants. This study is a two-factor factorial experiment with three replications in a randomized block design. First factor is type rhizobacteria which are without rhizobacteria, RZ3.L2.1, RZ3.L2.2, RZ3.L2.5. The second factor is the type of mycorrhizal wich are Glamus mycorrhiza, mycorrhizal and mycorrhizal Acaulospora sclerocystis, Data were analyzed by analysis of variance and DNMRT 5%. The results showed that the best treatment for the growth of the potato crop is rhizobakteria RZ3.L2.2 with mycorrhizal glamus. Keywords-potatoes, rhizobacteria, arbuscular mycorrhizal fungi. II.
