An investigation was carried out in order to evaluate some of the factors which influence the use of dwarf and semi-dwarf apple trees in commercial orchards in the Okanagan Valley of British Columbia.
Three determining factors were found to be of prime importance: the planting density of the trees in the orchard, the tree form as determined by the pruning and training system carried out and the nature of the rootstock used.
In the Doornberg Orchards at Okanagan Centre where the experiments were conducted, semi-dwarf trees on Malling VII rootstock trained as hedgerows and planted at a high density per acre gave the optimum earliest and total yields and returns.
The experiments were carried out from planting time up to the end of the sixth growing season. The variety of apple used in the experiment was Golden Delicious. / Land and Food Systems, Faculty of / Graduate
