“…In the literature it is possible to find different examples, some of them carried out in Andalusia, that analyze the relation between yield (Y) and irrigation water dose in olive grove (Lavee et al, 1990;Inglese et al, 1996;Pastor et al, 1999;Moriana et al, 2003Moriana et al, , 2007Perez-Lopez et al, 2007). In these studies, yield responses of different olive orchards to variable water supply are analyzed.…”

Economic valuation of irrigation water is done through the use of production functions for the case of the olive grove. In order to do so the integration of an agronomic model (based on the production function) and an economic model linked to the profitability of the crop (the ratio of revenue and operating costs) in the area under study is proposed. The study case encompasses the Guadalbullon River Sub-basin area, belonging to the Guadalquivir River Hydrologic Demarcation (Southern Spain). Within the overall deficit of the Guadalquivir River basin, the Guadalbullon River poses a special problem as it is unregulated and there are important irrigated fields on its banks, most of them olive groves. Net marginal value of water obtained (having deducted the variable costs of production including harvesting and irrigation) is€ 0.60 m–3 for the allocation of 1,000 m3 ha–1 and € 0.53 m–3 for the water right allowance of 1,500 m3 ha–1 (average for period 2005/2008). The results obtained support the recommendation by other authors suggesting the use of deficit irrigation in olive, additionally the high value of water estimated contributes to explain the substantial increase in irrigated olive area in Andalucia.

“…In contrast, when no complementary irrigation was applied in 2013, no significant differences for yield, and yield components were recorded due to the water irrigation regimes assigned the previous years. Since any effect on blooming and fruit set should be excluded, being water application started in mid-June, we might hypothesize that 15 m 3 and 20 m 3 water irrigation, applied in 2011 and 2012, may have reduced fruit abscission, as reported by Lavee (1990) and Inglese et al (1996) although this cannot be directly confirmed in the present study since fruit drop was not measured. Despite the initial hypothesis, there were no positive effects of summer irrigation on flower differentiation in the following year so that no re- (Fig.…”

“…Several studies have also recognized positive effects of an increased water supply to olive trees starting from 30% of the ETc return compared to rain-fed conditions on the fruit size, pulpto-pit ratio, mesocarp cell size, and oil content at harvest (Lavee et al, 1990;Inglese et al, 1996;Proietti & Antognozzi, 1996;Costagli et al, 2003;Lodolini et al, 2011;Gucci et al, 2007Gucci et al, , 2009Gucci et al, , 2011.…”

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.

“…Irrigation is highly effective in increasing yield and yield components such as fruit size, fruit number and oil content, moreover, irrigation affects the pulp-to-pit ratio, phenology and time of fruit maturation (Agabbio, 1978;Goldhamer et al, 1994;Michelakis et al, 1994;Inglese et al, 1996;Gòmez-Rico et al, 2006, 2007Dag et al, 2008;Servili et al, 2007).…”
