The aim of the present paper was to define the agroclimatological aptitude of the Argentinean semiarid and arid zones to produce industrial oil and biofuel from castor. Castor bean oil (Ricinus communis L.), which currently has more than 700 applications, has an ?unlimited? market because its uses are multiple and there is a growing international demand. In Argentina its production was always relegated to marginal soils, but since it ceased to be grown in 1989 castor oil is imported. Due to the international prices of castor bean oil, its multiple applications and in Argentina its diverse climate, this work on potential cultivation areas considering the species bioclimatic needs was carried out. To define the agroclimatic aptitude of this crop in Argentina, the climatic data of the meteorological stations corresponding to the period 1981?2010 was analyzed. Using available databases and geographical limits for the different variables, aptitude types were defined and mapped: optimal; very suitable; suitable with humid regime, suitable 1 with sub-humid regime; marginal due to humidity; marginal due to temperature; marginal due to frosts and not suitable areas. Areas classified as optimal and very suitable in the eastern sector of Argentina overlay with the areas for the production of traditional oilseed crops. So, its cultivation is not recommended. The areas that can be destined to its cultivation are the ones zoned as suitable,defined under conditions of sub-humid regime, with different thermal regimes. Therefore, land might be used in parts of the provinces of Salta, Jujuy, Tucumán, Chaco, Formosa, Santiago del Estero, Córdoba, San Luis, La Pampa, western Buenos Aires, La Rioja and Catamarca. This agro-climatic zoning model to determine potential production areas for castor bean can be applied to any part of the world, using the bioclimatic limits of the species presented in this work.
