Conteúdo: 	The aim of this study was to evaluate the effect of previously selected rhizobia on the yield of sudan grass, millet, aries grass and sorghum forage. The rhizobia studied: UFRGS Om57; UFRGS Om59 and UFRGS Om148, obtained from the collection of cultures of UFRGS Soil Microbiology Laboratory, the isolated adesmia EEL46210, donated by Epagri, and SEMIA929 and SEMIA6437 strains, released by the Ministry of Agriculture, Livestock and Food Supply (MAPA) for the production of inoculants for Ornithopus micrantus and Adesmia latifolia. In the experiments with each species of plant, in addition to the inoculated treatments, two control treatments without inoculation were conducted, one with the adding of nitrogen N dose equivalent to 100 kg N.ha-1 and the other with a dose equivalent to 50 kg N.ha-1. The study was arranged in a completely randomized design and lasted 45 days. The isolated UFGRS Os57, UFRGS Om148, EEL46.210, SEMIA929 and SEMIA6437 stimulate root dry mass of sudan grass. Isolated UFRGS Om57 induces higher plant height compared to Control N - at 15 and 30 days after emergence. In millet, the SEMIA 929 strain increased the shoot and root dry mass, height at 15 days, and the Relative Efficiency Ratio (RER%) is more than 150%. The inoculation with UFRGS Om57 isolate  stimulates sorghum shoot and root dry mass. For this treatment the RER% is 179%. There were genotypic differences among isolates of this study and the strains currently recommended for composition of commercial inoculants of Ornithopus micrantus and Adesmia latifolia.
