- Abstract
The study of the agroclimatic conditions allows to know the agricultural potential of a certain region, thus, the objective of this study was to evaluate the climatic water balance and the fitness agroclimatic of crops in order to provide information for the implantation in the mesoregions of Paraíba. The calculation of the water balance, elaboration of the evapopluviograma and the determination of the fitness agroclimatic of the cultures were made from a historical series of precipitation and air temperature. The water deficit in the soil is the main factor determinant of the conditions for the exploitation of a certain crop in the state of Paraíba. The agroclimatic conditions of the state of Paraíba allowed to classify 80% of the species studied in this study as full fitness, 50% moderate fitness and 20% restricted fitness. To ensure crop productivity, it is necessary to plan 100% of the mesoregions in agricultural planning, aiming at the implementation of irrigation systems with rational use of water, especially during periods of drought.
