The aims of this research was to study the net assimilation rate, growth and yield of rice with the application of PGPR in different rate of nitrogen fertilizer. The experimental was conducted in experimental farm of Agriculture Faculty of UNSOED Purwokerto. The research was arranged in Randomized Block Design with three replications. The first factor is PGPR consortium, and the second factor is dosage of nitrogen fertilizer. The observed variables were plant height, number of tillers, plant biomass, leaf greenness, plant biomass, net assimilation rate, relative growth rate and yield. Data were analyzed using ANOVA followed with DMRT test for mean comparison between group. The results showed that PGPR consortium inoculation and nitrogen fertilization have effect on root growth, leaf greenness, and plant biomass. The PGPR consortium R08 isolate + R11 isolate and nitrogen fertilizer at dose of 1.36 g plant −1 gave highest net assimilation rate of 5.87 g dm −2 week −1 . The highest grain yield was achieved at nitrogen fertilizer dose of 2.72 g plant −1 at 36.17 g per hill.
