Plant Growth Promoting Rhizobacteria (PGPR) affect Wati Plants (Piper methysticum Forst) growth at seedling stage

Abstract Plant Growth Promoting Rhizobacteria (PGPR) is consortium of active bacteria colonize root plants that play important role in improving growth. This research aims to figure out effect PGPR on wati ( Piper methysticum Forst) seedling conducted at the Screen House Yasa Mulya Village, Tanah Miring District, Merauke, Papua. study used Group Random Design as experimental design consisted 5 treatments, repeated times, so there are 25 units experiment. Data analyzed using Analysis Variance (ANOVA). analysis showed dose given significantly affect The best growth 70 days after planting found application 15 ml per 600 water (T4), this treatment shows results number shoots (3.60), length (7.02 mm), leaves (7.00), leaf width (7.78 cm), primary (12.60), (9.10 and volume (3.60 ml).
