Olive tree has been found within the habitats of Cyprus for a long time but, most of the olive cultivars are wild with low yield and low quality. High-density plantations are key factor for improving olive tree productivity and selection of the appropriate cultivar is crucial. The aim of current study was to test the performance and oil quality of five commercial clones cv. ‘Arbequina’, cv. ‘Arbosana’, cv. ‘Sikitita’, cv. Koroneiki and cv. ‘Tosca’ grown in high-density systems in Northern Cyprus in comparison with two local cultivars cv. ‘Kato Drys’ and cv. ‘Klirou’. The experimental studies were conducted in Guzelyurt in Northern Cyprus during 5 sequential crop years from 2013 (2nd growing year) to 2017 (6th growing year). Seedlings of commercial clones were planted with a pattern of 4 x 2 m (1250 trees ha-1) and local cultivars with a pattern of 5 x 5 m (400 trees ha-1). Results indicated that Arbequina, Arbosana and Koroneiki are the most precocious cultivars which bore fruits in the second year after planting and had the highest cumulative olive and olive oil yield in 6 successive growing seasons. However, Arbequina cultivar was also found to have higher free fatty acid contents (% oleic acid) than the IOC limit (0.8% oleic acid) for extra virgin olive oil.
