The rhizosphere of shallot (Allium ascalonicum L.) might harbored by many bacteria that have potency as Plant Growth-Promoting Rhizobacteria (PGPR). Therefore, we isolated and characterized the endophytic bacteria from shallot and found the potency as PGPR. This study was done in two stages, the diversity of endophytic bacteria and the colonization of various endophytic bacteria as plant growth promoters. The results showed that the endophytic bacteria had a high diversity of morphological characters. Endophytic isolate B2 has potential as PGPR in increasing shallot growth indicated by the number of leaf 35 sheet, weight of plant 875 g, and weight of bulb 46.50 g.

Keywords: Bacteria, Endophytic, Shallot, PGPR
