Résumé:
This work aimed to evaluate and map the potential of irrigated agricultural production for forage palm for the watershed of the region of the middle course of
the Paraíba River. Using SPRING, a map of soil irrigation potential and soil retention capacity was prepared and a partial map was generated through matrix
crossing. Using average annual rainfall data, the climate condition map was prepared. After using LEGAL, the agricultural production potential map was
generated through the matrix crossing between the partial map and the climate scenario. A full climatic condition (C1) was identified in 68.34% of the basin's
total; the full climatic condition with prolonged rainy season (C2) in 9.40%, and the climatic condition moderated by water excess (C3) in 3.92%, the climatic
condition Moderate by water deficiency (C4) in 18.34%, the unfit condition due to severe water deficit (C5) did not occur in the basin. The potential of irrigated
agricultural production for the culture of forage cactus did not present Very High (MA) and High (A) potential, the Medium (M) potential at 10.54%, Low (B) at
9.45%, and the Very Low potential (MB) in 80.01% of the basin.
