Abstract
The objective of this research was to elaborate the climatic risk zoning of pecan cropping (Carya illinoinensis) for Rio Grande do Sul state. Were collected of climate data and cropping phenological phases, was organized and spatialized using ordinary kriging and integrated through map algebra in ArcGis software 10.2.2. Each climate risk was classified in very low, low, medium, high and very high. As a result five risk indices: lack of chilling in the dormancy period, excess rainfall at the foliar expansion, flowering and fruits formation; temperature above 35ºC at the flowering and fruits formation; excess relative humidity at the flowering; and drought at the pecan growth period. The dynamics of climate variables in the state territory indicate that pecan climatic requirements is attended. The State presented 48.4% of the area with very low risk and 51.6% with low risk. This means that this cropping has great potential for development in Rio Grande do Sul state.
