“…Results of our study are in contrast with Tognetti et al (2006) reporting no significant differences between rain-fed and 33% of ETc irrigated trees regarding the crop yield in both 'off' and 'on' years for Frantoio and Leccino cultivars in southern Italy. This is probably due to a different rainfall distribution in the area (periodical showers during summer) compared to the climatic conditions in this study.…”

Traditional olive orchards are usually not irrigated in the Mediterranean basin, but at those latitudes, the yearly rainfall is frequently insufficient to support equilibrated vegetative growth and high fruit and oil production. This three-year field study investigated the effect of complementary irrigation on olive tree vegetative growth, fruit and oil yield during a biennial alternate bearing cycle in a traditional grove under semi-arid conditions. Adult olive trees (Olea europaea L. cv. Nabali Baladi) were subjected to complementary irrigation in 2011 and 2012 ('on' and 'off' years, respectively) with 6, 10, 15 or 20 m3 of water per tree per season, which corresponded to 14.2%, 23.8%, 35.7% and 47.6% of the whole seasonal evapotranspiration (42 m3 of water per year), respectively. Rain-fed trees were used as control. In 2013, no complementary irrigation was supplied, and any residual effects on the yield components were determined. Results showed that none of the irrigation regimes affected vegetative growth, or olive fruit size (mesocarp and endocarp), as fresh and dry weights. The fruit and oil yield per tree increased compared to the rain-fed conditions only when the threshold of 15 m3 was exceeded, thus inducing a higher crop load compared to the rain-fed control during the 'off' and even further during the 'on' year. No residual effects were registered in 2013. The study showed that complementary irrigation of at least 35% of the seasonal water requirement can produce remarkable positive effects on fruit yield especially during 'on' bearing years.

“…Second, at end of summer and beginning of autumn until harvest, active photosynthesis is required for production and transport of the sugar-alcohol mannitol to fruit for oil synthesis. Tognetti et al (2006) in southern Italy observed that oil production was linearly related to irrigation amount during early autumn. In olive, the main objective in RDI is not to control vegetative growth, as in peach (Chalmers et al 1981), because shoot growth occurs mainly in spring and slightly in autumn, coinciding with the first and second periods of drought sensitivity.…”

Maximum production in hedgerow olive orchards is likely not achieved with maximum evapotranspiration over the long-term. Thus, regulated deficit irrigation (RDI) should be considered as a management option. Four irrigation treatments were evaluated during the summer when olive is most drought resistant. Control (CON) was irrigated to maintain the rootzone close to field capacity. Severe water deficit was applied by irrigating 30% CON from end of fruit drop to end July (DI-J) and from end July until beginning of oil synthesis (DI-A). Less severe water deficit was applied during July and August (DI-JA) by irrigating 50% CON. Flowering, fruiting, abscission, fruit development, fresh and dry weight of fruits, and oil production were evaluated. There were not significant differences in number of buds initiated, number of fruits per inflorescence and fruit drop. Oil production was significantly different between irrigation treatments in all experimental years. CON produced more oil and fruit with higher oil% than DI-A and DI-JA. Oil production of DI-J was not significantly reduced compared to CON and oil% was greater. DI-J was the most effective RDI strategy; with 16% less applied water relative to CON average loss in oil production of 8% was not significantly different to CON. While DI-JA saved most water (27%), oil production was reduced by 15%. Greatest loss in oil production (21%) was observed in DI-A with water saving of 22%.

“…With reduced water resources available for agriculture, scientists and engineers have developed innovative technologies such as deficit irrigation programs aimed at increasing the efficient use of irrigation water (Kirda, 2002;Tognetti et al, 2006;Fereres and Soriano, 2007). Water deficits during a specific crop development period significantly affect crop yield; therefore, the yield response to water stress has been studied extensively.…”

“…Irrigated agriculture used more than 70% of the water withdrawn from Earth's rivers (FAO, 2003). Crop production is highly dependent on water availability, and any shortage of water has a significant impact on the final yields of crops (Kirda, 2002;Tognetti et al, 2006;Quiroga et al, 2011); however, water is a finite resource for which competition is increasing among the agricultural, industrial, and domestic sectors.…”
