Abstract : A study was conducted to evaluate the effects of pruning at 2.5 m height above the soil and branches pruning at 2.0 and 1.8 m; and application of paclobutrazol (PBZ) to the soil at 2.5 g/tree on the vegetative growth, yield and productive efficiency of mango cultivars 'Haden', 'Tommy Atkins', 'Springfels' and 'Edward' grafted on 'Criollo' and planted at 6×6 m (278 trees/ha). The treatments were: control (C), C+PBZ, pruning (P) and P+PBZ, P+lateral branches pruning at 1.8 m (P+L) and P+pruning of internal primary branches (P+I). The yields (t/ha) during 2000-04 for the different treatments were: 40.8 (C), 36.1 (C+PBZ), 26.0 (P), 26.9 (P+PBZ), 21.2 (P+I) and 25.8 (P+L). These yields were higher (>200%) than that reached by low tree density system (69 trees/ha).
