The formula application of biological nitrogen and phosphate solubilizing bacteria (NPSB) were suitable and possible potential for plant growth and yield of rice ( Oryza sativa Linn.). This study aimed to investigate the formula application effect of NPSB on plant growth and yield components responses at different type soil paddy fields. The experiment was conducted at the greenhouse of the Center for Research and Development of Agricultural Biotechnology and Genetic Resources, Bogor District, West Java Province, and arranged in a factorial randomized block design with two factor and three replications. Biometrical observations found significantly highest in formula application at vegetative and generative stage. The maximum number of tillers was observed on 10 7 at alluvial type soil which was 11.0, followed by 10 5 μmol/ml at latosol type soil which was 10.3. The effectiveness of tiller after 63 DAT was observed on all formulate at alluvial type soil. The linear relationship between the number of tillers per plant and filled grain number per plant as influenced by the application of formulated isolate at alluvial and latosol soil type had only 32.38 % (r = 0.569). The highest filled grain was on 10 7 μmol/ml formula isolated at latosol soil type which was 826 grain per plant at latosol soil type. The weight of grain per plant had a 96.78% contribution to the total filled grain per plant of rice(r = 0.984) indicates a very strong positive correlation between the weight grain and the number of filled grains per plant.
