Abstract: The rice crop is annual, adapted to highlands, floodplains or flooded, representing high importance for human consumption, requiring research for the optimization of cultivation and its initial development. The objective of the present work was to evaluate the germination and vigor of rice seeds, with the application of inoculant with bacteria of the species Azospirillum brasilense. The experimental design used was completely randomized, using six inoculant doses containing A. brasilense, with 4 replications of 50 seeds each, using the SCS 121 CL cultivar. Germination evaluations were carried out daily up to 14 days, the first count test on the 5th day and the second count on the 14th day after sowing. The germination speed index and the biometric parameters were also performed at the end of the experiment. The dose of 4.0 mL 1000-1 seeds of inoculant was the treatment that resulted in a percentage of germination in the rice seed. Root length increased with higher doses, however there was no significant difference in root dry mass. The different inoculant doses do not interfere with the development of the rice aerial part.
