The variety of our olive groves
Over 97% of olive trees in the valley of Belice, are the variety Nocellara del Belice; cultivars of modest growth, with branches in fruit hanging, self-incompatible, with productivity constant, large-fruited (5-8 grams), almost spherical, firm and crisp, deep green before dell’invaiazione that it turns red when ripe winey. The pulp represents 85% of drupa, the oil yield is around 18-20%, the quality is excellent; for this reason it is considered dual-purpose cultivar (oil-table). This variety, prefers fresh soils and loose, but fails to give satisfactory productions in poor condition.
The remaining 3% of plants is represented by cultivars Buscionetto, Giarraffa, Cerasuola or Palermitana. Their sole purpose is to pollinate the Nocellara del Belice, excluding Cerasuola, since it is androsterile.
The cultivar Buscionetto (Biancolilla Caltabellotta) has a force content and foliage espansa- variety partially self-compatible; It produces alternate years fruit whose oil yield is 16-23%. The oil quality is good, very good shelf life; It has good resistance to major diseases. The plasticity of adaptation is remarkable.
The cultivar Cerasuola (sin. Palermitana) is erect and has a high vigor. The plant is androsterile, with high productivity. The oil yield is higher than 20%, the quality is good. The cultivar has a good plasticity of adaptation.
The cultivar Giarraffa has a medium vigor and erect foliage. It is partly self-incompatible, with an average productivity and constant over the years. The fruit is large, early about the enlargement, used as table olives, both green to black; the oil yield is low (15-17%), the quality discreet.
