Abstract
Macadamias are generally harvested from the ground in Australia. The duration of nut fall varies from a few weeks to several months depending on cultivar and growing conditions. This has economic consequences for the grower since several passes may be required for harvesting the crop. The quality of nuts may also deteriorate on the tree prior to nut fall or on the ground awaiting collection. Summaries of the past three years research examining several factors related to nut fall and harvesting will be presented. This will include morphological description of the tissues that separate to allow nut fall. Differences in the period between nuts reaching maturity and unaided nut fall will be shown for a range of cultivars from different locations. The period during nut development when Ethrel promotes drop will be identified and the effect of different doses on nut fall will be described. The longer-term effects of both tree shaking and treatment with Ethrel on the return yields will be described. Options for promoting nut drop and improving harvest scheduling in light of these results will be discussed.
