The objective of this work was to diagnose banana yield (Prata and Nanica) in Minas Gerais and to identify, by zoning, the edaphoclimatic aptitude of Vale do Rio Doce mesoregion for commercial production of this fruit. Information regarding to the period from 2000 to 2010 were collected from CeasaMiNAS. Then, they were organized in spreadsheets by using percentile 80 for the supplied quantities of banana (Prata and Nanica) as cut factor for cities in the state of Minas Gerais. Thus, the following conclusions could be drawn: the major producers of banana are Matias Cardoso, Jaíba, Janaúba, Nova Porteirinha and Pirapora (northen Minas mesoregion) and Pedralva (Southern, southwestern Minas mesoregion); the production of banana Nanica stands out in Matias Cardoso, Jaíba and Janaúba (Northen Minas mesoregion), Uberlândia (Mineiro Triangle mesoregion) and Nova União (metropolitan mesoregion of Belo Horizonte); in all main producer cities, the offer of banana is inversely proportional to the prices practiced in CeasaMinas. Zoning was performed by analyzing temperature, altitude, rainfall, water deficit and soil of the Vale do Rio Doce mesoregion. Information from thermal conditions was given by Instituto Nacional de Meteorologia (INMET Brazilian Metheorology Institute) and estimates of the mathematical model. Altimetry data were acquired by the digital elevation model by using images from ASTER. Rainfall data were collected from literature and from Agência Nacional de Águas (ANA Brazilian Water Agency). To obtain data of water deficit, normal water balance was calculated. Information on soil was from Programa GeoMinas. Results evidenced that banana can be grown with irrigation in 28.7% of the zoned area (around 11,000 km2). The microregions of Guanhães, Mantena and Aimorés stood out and 71.3% of the mesoregion is unable xiiidue to altitude and type of soil. In addition, the Vale do Rio Doce mesoregion does not present preferential areas or with aptitude to outdoor banana cultivation in dry areas.
