Total water requirements of green beans, cabbage, carrots, cucumber, eggplant, lettuce, melons, okra, onion, potatoes, pumpkin, sweet peppers, sweet potato and tomatoes were estimated at Fortuna Agricultural Experiment Substation, Juana Diaz, in the semiarid south coast of Puerto Rico. The modified Blaney-Criddle model was used to estimate monthly consumptive use and net irrigation requirements with temperature, rainfall data. Twelve planting schedules and 4 crop durations of 90, 105, 120 and 150 days were considered.
