Abstract	Aiming at evaluating the effect of two irrigation strategies on the production and water-use efficiency (WUE) of 'Palmer' mango trees, we developed two experiments: one of them used Regulated Deficit Irrigation (RDI), irrigated by micro sprinklers, and the other one 1 Acadêmico (a) de Agronomia, IF Baiano, GuanambiBahia.

Mesquita et al. used Partial Rootzone Drying (PRD), irrigated by drip irrigation, in the municipality of Guanambi. A randomized block design with five treatments for each management and four replicates was used. In the RDI: T1, full irrigation, 100% ETc, at three stages of fruit development: stage I, fruit setting; stage II, fruit growth and stage III, physiology maturation,; T2, 100% of ETc at stages II and III and 50% of ETc at stage I; T3, 100% of ETc at stages I and III and 50% of ETc at stage II; T4, 100% of ETc at stages II and III and 50% of ETc at stage III; T5, irrigation with 50% of ETc at stages I, II, and III; and, in the PRD at the three stages: T1, full irrigation, 100% of ETc using conventional drip irrigation system; T2, 100% of ETc; T3, 80% of ETc; T4, 60% of ETc e T5, 40% of ETc. Using PRD with irrigation depth reduction of 40% of ETc reduces the productivity of 'Palmer' mango when compared to full irrigation and to PRD with 100% of ETc. RDI with 50% of ETc at stage III allows a better productivity in comparison with the application of 50% of ETc at the three stages of fruit development.
