Description:	Irrigation management is essential for applying the required amount of water to crops. This study evaluated the growth and yield of cowpea cultivars as a function of water regime. The experiment was conducted in Teresina, Piauí State, Brazil, from July to September 2022. The experimental design comprised a randomized block in a split-plot scheme with four replicates. The treatments comprised five water regimes (133.80, 191.70, 249.00, 303.00, and 357.00 mm per cycle) and two cowpea cultivars (BRS Inhuma and BRS Olho Negro).
