    Cactus pear is one of the most cultivated species and an important alternative to support food for livestock in the semi-arid region of the Brazilian Northeast, however, some locations do not have a suitable climate for its development, requiring water supplementation. Its productivity and development has better result in the criterion of irrigation management. Thus, the objective of this study is to evaluate the growth and development of cactus pear, using the irrigation management strategy on productivity in different water regimes. The experiment was carried out in a rural property in the municipality of Canindé de São Francisco-SE. The trial was carried out in randomized blocks with 4 repetitions in a 4x2 factorial scheme, with four varieties of palms in two water regimes. The irrigation system used was located with dripped tapes. The agronomic variables studied were: plant height and width, number of paddles per plant, length, width and thickness of the paddle, green mass weight and dry mass weight. To evaluate the production cost in the second cycle of the plant's culture, the effective operating cost (EOC), cost with administrative charge (CEA) and the total operating cost (TOC) were evaluated. The small variety responded positively to the application of irrigation. The varieties: elephant ear, Mexican, girl's hand and giant. There was no increase in the number of rackets with the application of irrigation. The acquisition of mineral fertilizers is the factor that most burdens the total operating cost.
