Agroforestry systems with eucalyptus are widespread, however, among some potential species, improvement work is incipient, and it is necessary to evaluate and rank the provenances used. In this context, the objective was to evaluate the potential of establishment of four provenances of Eucalyptus cloeziana in agroforestry systems. The experiment was established in an arrangement ((3 x 2) + 10) m, in a complete randomized block design with eight replications and 15 plants per plot. The provenances tested came from seeds from the populations of Itamarandiba, Carmo da Mata, Virginópolis and Belo Horizonte. At 26 months of age, survival, height (H) and diameter at breast height (DBH) were measured, and volume (Vol) and crown area (AC) were estimated. Progenies did not differ in survival. Variables H and DC stand out for the progenies Itamarandiba, for Vol and AC the origin of Belo Horizonte had a performance below the others. In conclusion, Eucalyptus cloeziana presents a good adaptation to the silvopastoral system conditions in Bom Sucesso – MG and highlights Itamarandiba provenance as the best silvicultural performance.
