| Abstract:
Eleven to twelve year old olive trees, trained to vase and monocone, and harvested using an orbital shaker, showed high fruit removal (93-96%) even under conditions of high fruit detachment force. Canopy volumes of 29-39 m3 were well dominated by the vibrator. The vase training system responded to mechanical harvesting with the trunk shaker, also presenting good productive reliability. Among the varieties, Leccino showed the best response, both during the first and the second harvesting period, because of its high fruit weight and short peduncle: the oil content was high during the second period (the first ten days of November). Frantoio and Pendolino cultivars showed good fruit removal during the second period, when the fruit detachment force began to reduce. The Dritta cultivar, characterized by a medium fruit detachment force and by good fruit oil content, can be harvested early. The varieties showed the following range of adaptability to mechanical harvesting from the most adaptable to the least: Leccino, Frantoio, Pendolino, Dritta. With regards to the harvesting period it is possible to indicate the following sequence: Dritta, Pendolino, Frantoio, Leccino. | |
