Mechanical harvest of grapes: assessment of the physical-mechanical characteristics of the berry in order to improve the quality of wines
Evaluation of the efficiency of different harvesting methods of olives
This paper reports the results of experimental tests carried out in Sicily about the harvesting of olives. Three varieties were selected (Biancolilla, Cerasuola and Nocellara del Belice); the tests were performed in three different periods with three different harvesting systems: manual, manual with pneumatic combs and mechanical harvesting. The aim of this study was to evaluate the work capacity and productivity of the three harvesting systems and the period maximising the mechanical harvesting efficiency. The damages caused to the trees after mechanical harvesting with a variable frequency shaker were also evaluated. Naturally fallen olives, Jean’s maturity index, detachment force, harves…
Influence of tree's structure on the efficiency of the mechanical harvest of olives
This study represents an analysis about the influence of the structure of the plant and the drupes’ position on the efficiency of the mechanical harvest of olives. The aim is to study the eventual correlations between some geometrical characteristics of the plants and the harvest efficiency. The experimental tests were carried out in an olive grove sited in Castelvetrano, province of Trapani; the variety was Nocellara del Belice, the plants “globe” shaped. Some morphological surveys were carried out on a sample of trees. The mechanical harvest was performed with a trunk shaker provided with an upside down umbrella. After the harvest, the residual production was quantified for each bud in or…
