Abstract : The effects of open vase, closed vase, central leader, palmette and standard pruning systems on mango cv. Sensation tree size, yield and fruit size were compared with unpruned and untrained controls in South Africa during 1994-96. Post-harvest pruning and pruning after fruit set were also evaluated as measures to maintain tree size of each of the tree training systems. Tree size was influenced by pruning and training system. Control trees had the largest tree size and fruit yield (cumulative yield of 124.44 kg/tree compared with 69.22-98.08 kg/tree for the pruning treatments), although annual yield was reduced in 1997 due to competition as control trees started to shade one another out. Post-harvest pruning and pruning after fruit set increased fruit size and reduced the problems of alternate bearing. A study was also conducted for 2 seasons on a commercial farm with Tommy Atkins, pruned to a pyramidal system and compared with untrained trees. No reduction in fruit yield due to pruning was observed if trees were pruned immediately after fruit harvest. In addition, fruits from pruned trees exhibited better colour development than those from control trees.
