Abstract
This study was conducted in Ajloun area, Jordan, on two local olive cultivars: ‘Nabali Balaldi’ and ‘Nabali Mohassan’ to evaluate the effect of harvesting method on harvesting efficiency and olive oil quality.
Two harvesting methods were compared: hand harvesting and pneumatic comb machine harvester.
The experiment consists of 4 replications, 8 trees of each cultivar, and 4 branches on each tree were labeled for recording number of harvested fruits and detached leaves.
Results showed that mechanical harvesting using the battery operated machine (pneumatic comb machine) increased harvesting efficiency of the worker by 4-7 times compared with hand harvesting.
Also the result showed that hand harvesting had higher percentage of harvested fruits for ‘Nabali Baladi’ and significantly lower percentage of detached leaves for both cultivars.
Results showed no significant differences between hand and machine harvesting on fruit oil content, olive oil acidity, peroxide value, K 232, K270, ΔK and fatty acid composition for both cultivars.
Based on our results, we advise olive farmers in Jordan to use pneumatic comb machine as an alternative to manual harvesting, since it increases the worker efficiency (productivity) by 4-7 times compared to manual harvesting and without affecting negatively impacting the oil content and the quality parameters of the olive oil produced.
