Abstract
Rice (Oryza sativa) is one of the food commodities which is the staple food for almost all Indonesian people. Plant Growth Promoting Rhizobacteria (PGPR) is a biological fertilizer that can stimulate plant growth and suppress phytopathogens. This study aimed to examine the effect of PGPR on the vegetative and generative growth of rice plants and the effect of PGPR application on the incidence and severity of rice panicle blight. This study was arranged based on a Randomized Block Design (RBD) consisting of 11 treatments with different frequency of PGPR application at different ages of rice after planting. The treatment was repeated 5 times, so there were 55 units of observation. PGPR, in general, has a positive impact on vegetative growth, rice germination and generative growth of rice plants, the number of tillers, production weight, and the weight of 100 seeds. The high application of PGPR has a disease suppression effect on rice panicle blight, although it does not show significantly different results from the control. The best PGPR treatment to get high production and suppress the incidence and severity of disease was PGPR treatment on seeds and PGPR application at 7, 14, 28, 42, 56 DAP.
