Conteúdo:	In this paper we evaluate the agricultural efficiency of the municipalities of the state Rio de Janeiro and assess the influence of contextual variables on the performance. The scores are computed by means of Data Envelopment Analysis (DEA) models, where inputs are land, labor and capital (or technology), and the value of crops and of livestock productions are the outputs. Covariates are related to soil evaluation (susceptibility to erosion and land use suitability) and to socioeconomic factors. The results show that high levels of susceptibility to erosion influence negatively and significantly the efficiency scores. The land suitability to agriculture and the land suitability to livestock are positively associated with performance. The presence of family-based farmers favors the agricultural performance of the assessed municipalities.
