In November 1988, in the Province of Macerata (Central Italy), an irrigated olive orchard was planted utilising the cultivars Frantoio, Moraiolo and Nostrale di Rigali trained to monocone and vase (7 x 6 m spacing). The results of the observations made from planting to 1992 are reported. The vase training system caused a bigger growth of the tree than the monocone; the vegetative development was: cv. Moraiolo less than Nostrale di Rigali which was less than Frantoio. The time needed for winter pruning was about 30% less with the vase training system with respect to the monocone. Fruit-set and fruit-drop were higher, respectively, in Frantoio and Nostrale di Rigali, while comparing the training systems, these parameters were not different. The cv. Frantoio had the highest cumulated yield per tree followed by the cvs. Moraiolo and Nostrale di Rigali; between training systems only cv. Frantoio trained to vase had a higher yield than the monocone, whereas there were no significant differences in the other cultivars. The yield efficiency was highest in Moraiolo followed by Frantoio and Nostrale di Rigali. Except for a higher yield efficiency of Nostrale di Rigali trained to monocone there were no significant differences between training systems. Among the parameters relative to floral and fruiting biology, Nostrale di Rigali showed higher and lower ovary abortion and fruit set, respectively, than the other cultivars. The acidity and peroxide number of the oil were not substantially different between training systems and cultivars. The cultivar Moraiolo showed an higher polyphenolic content and oxidation stability of the oil.
