The irrigation practice, in a lot of situations, is the only way to guarantee agricultural productivity and economic and social development, especially in the semi-arid region of the Northeast Brazil that is characterized by rainfall irregularities. The objective of the present work was to quantify qualitatively the lands of the farm Agreste, located in the Microrregião do Alto Piranhas, Itaporanga - PB, in classes of potential aptitude for irrigation. For this was taken in consideration the soil characteristics and the available water resources. In the farm 16.80 hectares (3.29% of the lands) can be used for irrigation with restrictions. 144.96 hectares (28.38% of the lands) are irrigable, but only for special use. Finally, 349.04 hectares (68.33% of the lands) are not inapt for irrigated agriculture.
