Acreage dedicated to pomegranates in Tadla plain (Morocco) is estimated in more than 1400 ha. Pomegranate orchards are mainly irrigated by submersion. Therefore, water consumption is very high. This study aimed at estimating water requirements under the conditions of this area and evaluating the effects of different drip irrigation strategies on tree developpement and yield parameters. Five drip irrigation strategies were compared namely 60% ETc, 80% ETc, 100% ETc, 120% ETc and the own farm drip irrigation strategy. Daily mean ETc was calculated by using the Penman-Monteith formula for a period of 11 years. Results suggested that drip irrigation based on 120% ETc conditions constitutes the optimal drip irrigation strategy when vegetative growth, fruit yield parameters and water consumption are considered.
