Zusammenfassung: | This study aims at identifying by zoning the mesoregion of Vale do Rio Doce edaphoclimatic aptitude for the commercial production of banana. The factors used in the agro-climatic zoning were temperature, altitude, rainfall, water deficit and soil type. Information on the thermal conditions was acquired from the INMET and also using estimates from a mathematical model. Altimetry data were acquired using digital elevation model generated from ASTER images. Rainfall data were collected from literature and from the ANA. To obtain the data of water deficit a standard water balance was calculated. Soil information was provided by Geominas Program. According to the results it was evident that banana can be grown with the use of irrigation in 28.7% of the zoned area (about 11,000 [km.sup.2]) emphasizing Guanhaes, Mantena and Aimores microregion. It was clear that 71.3% from the mesoregion is unsuitable to produce bananas because of the altitude and soil type. Moreover it was also clear that the mesoregion of Vale do Rio Doce has no preferential and suitable areas for the cultivation of unirrigated banana. Index terms: Musa spp., zoning, mesoregion of Vale do Rio Doce. O objetivo desta pesquisa foi identificar, por meio de zoneamento, a aptidao edafoclimatica da mesorregiao do Vale do Rio Doce para a producao comercial de banana. Os fatores utilizados no zoneamento agroclimatico foram temperatura, altitude, precipitacao, deficiencia hidrica e tipo de solo. As informacoes sobre as condicoes termicas foram obtidas do Instituto Nacional de Meteorologia e por meio de estimativas de modelo matematico. Os dados altimetricos foram obtidos por meio do modelo digital de elevacao, gerado a partir de imagens ASTER da mesorregiao. Os dados de precipitacao foram coletados da literatura e da Agencia Nacional de Aguas. Para a obtencao dos dados de deficiencia hidrica, foi calculado o balanco hidrico normal. As informacoes de solo foram adquiridas do Programa GeoMinas. A pesquisa evidenciou que a bananeira pode ser cultivada com o uso de irrigacao, em 28,7% da area zoneada (1,1 milhao de hectares), com destaque para as microrregioes de Guanhaes, Mantena e Aimores. Por outro lado, 71,3% da mesorregiao sao inaptas para o cultivo da banana, em funcao da altitude e do tipo de solo. A mesorregiao do Vale do Rio Doce nao possui areas preferenciais e/ou aptas ao cultivo de sequeiro da banana. Termos para indexacao: Musa spp., zoneamento, Vale do Rio Doce. |
