Quantifying water use and water productivity of high performing apple orchards of different canopy sizes
Expanded Title:This study showed that high apple yields can be produced sustainably without using excessive amounts of water provided the canopy is managed optimally. Current ‘Cripps’ Pink’ canopy management practices promote the development of the red colour on the fruit and also have water saving benefits. High crop loads in this study did not necessarily have a deleterious effect on most fruit quality attributes in the high yielding orchards. In the high yielding ‘Golden Delicious’ orchards only fruit size was affected, and management of crop load is essential in this cultivar to produce export quality fruit and maximise water productivity. Length of the growing season of different cultivars appeared not to influence the seasonal total water use.
