    Bacteria that live around plant roots that sparked the growth of plants or Plant Growth Promoting Rhizobacteria (PGPR) are bacteria that are beneficial to the soil which forms colonies on roots and planting areas can enhance plant growth. One of the areas of plant roots is the root of the plant area of red beans (Phaseolus vulgaris l.). This article aims to study the influence of the concentration of PGPR (plant growth Promoting Rhizobacteria) and best influence on growth and yield of red bean crops. Moderate is the solution A = 0 ml L-1 solution, B = 5 ml L-1 solution, C = 10 ml L-1 solution, D = 15 ml L-1 solution, E = 20 ml L-1 solution and F = 25 ml L-1 solution. The parameters observed were higher plants (cm), number of leaves (blades), the number of pods (fruits), the number of seeds (fruits), wet weight of pods (g) dried pods, weights (g), the wet seed weight (g) and the dry seed weight (g). The results showed that the concentration of the granting of PGPR has no effect against plant height at the age of 14 days after planting (DAP) and the number of leaves on each treatment. But giving influence on plant height at age 28 and 42 DAP, the number of pods, number of seeds, the weight of the wet, heavy pea pods dry, wet, and heavyweight of the seeds dry. The concentration of PGPR in 15 ml L-1 treatments have the best effect for the red bean crops.
