  • Tree development, yield and quality characteristics of fresh fruit and oil were evaluated under different water regimes for five years. Growth parameters such as canopy, trunk cross section area and pruned wood showed little differences between the rain-fed control and the lowest irrigation level and between treatment T2 and T3 while differences were evident between the control and treatment T2 Yield, fruit size, pulp-stone ratio and dry matter content of fruit peaked at an irrigation depth of 66% of ETc, while higher volumes did not significantly increase yield, suggesting that complete replacement of water loss by the crop is not recommended. Irrigation regimes did not affect the oil content calculated on dry weight basis and the increase in oil per hectare was explained according to the increase in fruit dry matter content and number of fruit for Kalamata. The fatty acid composition, sugar and acid content of the oil were not affected by irrigation, while the total polyphenol decreased up to treatment T2. In the most irrigated treatment bitterness and pungency of the oil slightly decreased as compared with the rainfed control, while fruiting was unaffected by irrigation. (literal)

Abstract
  • Tree development, yield and quality characteristics of fresh fruit and oil were evaluated under different water regimes for five years. The olive cvs. Ascolana Tenera, Kalamata, Nocellara del Belice, Maiatica and Itrana were tested in a factorial combination of four irrigation regimes: a rainfed control (T0) and three treatments (T1, T2, and T3) irrigated daily with a restitution of 33, 66, and 66% of ETc. In all years the lowest values of soil water content and xylem potential were detected in September and early October in T0, during the phenological phase of rapid enlargement of fruit cells, while values were near field capacity during the irrigation season in treatment T3 Growth parameters such as canopy, trunk cross section area and pruned wood showed little differences between the rain-fed control and the lowest irrigation level and between treatment T2 and T3 while differences were evident between the control and treatment T2 Yield, fruit size, pulp-stone ratio and dry matter content of fruit peaked at an irrigation depth of 66% of ETc, while higher volumes did not significantly increase yield, suggesting that complete replacement of water loss by the crop is not recommended. Only Kalamata showed a higher yield of T3 over T2. Irrigation regimes did not affect the oil content calculated on dry weight basis and the increase in oil per hectare was explained according to the increase in fruit dry matter content and number of fruit for Kalamata. The fatty acid composition, sugar and acid content of the oil were not affected by irrigation, while the total polyphenol decreased up to treatment T2. In the most irrigated treatment bitterness and pungency of the oil slightly decreased as compared with the rainfed control, while fruiting was unaffected by irrigation. (literal)
