S18.005.  aThe objective of this work was to study the growth and productivity of fruits of mango cultivated under irrigation by using of the “Partial Root Drying” (PRD) in the semi-arid of Bahia State. Treatments were applied at different phenological phases of the crop (flowering; fructification and stability of fruit growth). Irrigation water depth was determined based upon crop evapotranspiration calculated using reference evapotranspiration from an A pan evaporation. The crop was irrigated by a drip system of two lateral lines per plant row. The partial root drying was accomplished by turning on and off water emission from lateral lines that were located at both sides of each crop row of the plot at different time intervals (7, 14 and 21 days). Treatments consisted of full irrigation (100%); application of 30% and 50% with PRD at intervals of 7, 14 and 21 days in all phases; application full irrigation of during phase I and 50% in the phases II and III with partial root drying at intervals of 7, 14, 21 days during the remaining phases; and also the treat-ment in which just one lateral line remained on at one side of the tree during all phonological phases. The experiment followed a random block design with three replications. The variables number of fruits, total productivity, medium weight of fruits and medium productivity were not affected for the treatments with PRD in none of the studied phases.  aManga  aMango1 aCOELHO, E.
