vase, closed vase, central leader, palmette and standard pruning systems
were compared with unpruned controls in experiments at Nelspruit, South
Africa. Post harvest pruning and pruning after fruit set were also
evaluated with each of the tree training systems as measures to
maintain tree size. The study was conducted on cv. Sensation planted at
7 x 3 m and cv. Tommy Atkins planted at 8 x 2 m. Results indicated that
the spacing of Sensation trees at 7 x 3 m was too wide and that a
spacing of 5 x 2 m would be better. Training to an informal pyramid
(intermediate of central leader and closed vase systems) was
recommended to produce a yield exceeding 30 t/ha after 7 years. As
Sensation is a late cultivar rejuvenation pruning on the bearing tree
in October/November was possible, whereas the early cultivar Tommy
Atkins should be pruned immediately after harvest. |
