Abstract

There are currently several bioclimatic unit systems beyond the degree-day system, although their use and limitations are still little known in contemporary agriculture. . In this context, this study evaluated the performance of the Geslin Heliothermic Index (GHI) for different crops spread in an area of humid subtropical climate, with the case study of the municipality Guarapuava (PR). The comparison between the ideal GHI for potato crops in each production phase and the actual GHI during the 2008-2013 seasons enabled to determine the influence of thermal conditions for agricultural cultivation in the region. The data were provided by the Agronomic Institute of Paraná - IAPAR and analyzed by classical statistics, which served as the basis for the choice of the index used.
