Abstract

[Autom. eng. transl.] Currently the solutions proposed for the renewal of Italian olive growing are the intensive plants (300 p / ha) and the super-intensive plants with 1600 p / ha and beyond. To evaluate the productive and agronomic responses of the two types of plants, in 2006, plants were compared to the cv. Arbequina (reference cultivar) and cv. Frantoio, Leccino, Moraiolo and Maurino cultivated in two olive groves, differing only in plant density, one intensive (approx. 300 plants per hectare) and the other super intensive (1667 p / ha). The Arbequina and Maurino varieties showed early production , while the Leccino and Frantoio varieties are the major development. This was manifested in the two types of plant, even if with different values, as in the intensive plant there was a greater initial vegetative development at the expense of production. Subsequently the plants of the intensive olive grove showed greater volumes and greater unit productions. The mechanical harvesting was applied in the super-intensive in 2009 and 2010 with a grader, and in 2010 in intensive, with trunk and interceptor vibrator, with high collection yields in the super-intensive and for all varieties, while, in intensive, Arbequina and Moraiolo had lower percentages, respectively, due to the small size of the fruit and the high resistance to detachment. The quality of the oils, referring to the acidic composition and to the sensory evaluation, was high in all varieties. As for the polyphenol content, the Arbequina cultivar showed lower values in 2009 and 2010 than other varieties. In conclusion, in Central Italy, from the data acquired so far, the Maurino cultivar is the one that has shown a better answer, together with the cv. Arbequina, for cultivation in olive groves with a high plant density; while the other cultivars observed, namely Frantoio, Leccino and, partially, Moraiolo, due to high vigor or due to late fruiting, presented a better adaptability for medium density olive groves (300 p / ha).
