“…The same treatments (full irrigation, SDI and RDI) were tested in an olive orchard (cv. Arbequina) in Cordoba by Iniesta et al (2009). Both DI treatments applied the same seasonal amount of irrigation, about 25% of the control.…”

“…Many experiments have revealed reductions in vegetative growth induced by DI (Moriana et al, 2003;Iniesta et al, 2009). This effect, which is of great interest for controlling canopy size and for reducing the costs associated with specific agricultural practices, may reduce the number of fruits per tree.…”

“…Fortunately, RDI has been reported as useful for olive oil production (Alegre et al, 2002;Moriana et al, 2003;Iniesta et al, 2009), and the second phase of fruit development, when pit hardening occurs, seems to be the most resistant period to such water deficit. The above authors reduced or even withheld irrigation from the beginning of massive pit hardening to two weeks before the beginning of ripening (July 1-15 to September 15-20).…”

Water has become the most precious of natural resources in many areas of Spain and, since agriculture is the major consumer of water, improvements in water use efficiency are increasingly sought. Regulated deficit irrigation (RDI) is an irrigation strategy based on applying only a fraction of the plant water requirements during certain periods of plant development. The paper reviews the available information on RDI strategies, in woody tree crops and vines based on studies by Spanish research groups. Both the promising results obtained and the drawbacks are covered.

“…Recently, other authors (Patumi et al 2002;Tovar et al 2002;Marsilio et al 2006;García et al 2014) reported that drupes from irrigated olive trees are characterized by lower contents in phenolic compounds than those from not irrigated trees, evidencing an effect of the irrigation on the chemical composition of the drupes. However, the effects of different regulated deficit irrigation (RDI) strategies applied to olive orchards have been evaluated, so far, on the drupes for oil extraction rather than table olive production (Goldhamer 1999;Iniesta et al 2009). Following this trend, a large number of scientific papers have been published on the quality of olive oils produced from drupes obtained from trees subjected to irrigation (Pastor et al 1998;Gómez-Rico et al 2006, 2007Servili et al 2007), but no information on fermented table olives is available.…”

Effects of irrigation treatments on the quality of table olives produced with the Greek-style process

The irrigation of olive orchards is commonly applied to produce table olives with optimal size. No data have been published on the microbiological quality of drupes from irrigated olive groves during fermentation. The trials T100 and T50 (receiving a water amount equivalent to 100 % and 50 % of the required amount, respectively) and control T0 (rainfed trial) were monitored during two consecutive years. The results showed a significant increase of equatorial diameter and flesh:pit ratio of irrigated drupes. The decrease of pH and the numbers of lactic acid bacteria (LAB) registered for the irrigated trials during the fermentation were more consistent than those displayed by control T0. Lactobacillus pentosus, Lactobacillus plantarum, Lactobacillus coryniformis, and Pediococcus pentosaceus for LAB and Candida boidinii, Candida diddensiae, and Wickerhamomyces anomalus for yeasts were isolated at the highest concentrations. The global sensory acceptance was better for irrigated trials than control T0. The statistical multivariate analysis showed that the effect of irrigation was independent of the seasonal variability and it clearly distinguished the T100 and T50 trials from rainfed control. Irrigation improves significantly the quality of table olives. Interestingly, all explorative multivariate analyses showed low dissimilarity between irrigated trials; thus, the thesis T50 represents an effective approach to save water in olive orchards without compromising the quality of table olives.

“…When regulated deficit irrigation in the reason of 25% of the ETc was applied in southern Spain (Mediterranean climate with average 496 mm rainfall during the three-years experimentation), fruit yield was significantly decreased in the 'on' year (high fruit production) and recorded no differences in low-yield year ('off' year) compared to 100% of ETc supply (Iniesta et al, 2009). No significant differences, compared to the full ETc supply, were recorded for the vegetative growth when water irrigation was reduced to 50% of the ETc in harsh weather conditions (130.5 mm of rainfall in the two-year study period) of Kuwait (Bhat et al, 2012).…”

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.
