POSSAS, José M. C. et al. Agroclimatic zoning for physic mut crop in the state of Pernambuco. Rev. bras. eng. agríc. ambient. [online]. 2012, vol.16, n.9, pp.993-998. ISSN 1415-4366.

This study aimed to realize the agroclimatic zoning of Jathopra curcas L. crop in the State of Pernambuco. For this, climatic data of air temperature and mean rainfall of 146 meteorological stations and 73 series with historical data over 30 years and another 73 with less than 30 years but more than 20 years of observations were used. The choice of Jatropha has been motivated by the potential of this crop as a source of renewable energy to replace fossil fuels as well as for its rusticity and a new option for regions of semi-arid climate, as it occurs in the Northeast region. The selection of the study area is related to climate variability in the State and the potential that this crop has in regions where there is low precipitation. According to the study, the State of Pernambuco has 14.92% of areas suitable for production of Jatropha, 44.26% of the restricted areas by water deficit, and 40.82% of unsuitable areas.
