“…Those authors registered a significant increase of weight, volume, and flesh:pit ratio. 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).…”

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.

“…The irrigation of table olive trees has several positive effects: it improves vegetative and reproductive growth, increases the size and uniformity of drupes, and reduces fruit drop and alternate bearing (Lavee et al 1990;Michelakis 1990;Patumi et al 2002).…”

“…Traditional methods employ the ETo-crop coefficient approach (ETa = EToˆKc, where ETo is the reference evapotranspiration (mm day´1) and Kc is the crop coefficient) [5,6]. The accurate estimate of ETa or latent heat flux (LE) is an important factor for establishing irrigation strategies such as regulated deficit irrigation (RDI), which has been successfully applied on olive orchards to increase water productivity and olive oil quality [7][8][9][10]. In addition, Cohen et al [11] and Ortega-Farias et al [12] indicated that the site-specific irrigation management (SSIM) can be used as a technical tool to improve water productivity.…”

Estimation of Energy Balance Components over a Drip-Irrigated Olive Orchard Using Thermal and Multispectral Cameras Placed on a Helicopter-Based Unmanned Aerial Vehicle (UAV)

A field experiment was carried out to implement a remote sensing energy balance (RSEB) algorithm for estimating the incoming solar radiation (Rsi), net radiation (Rn), sensible heat flux (H), soil heat flux (G) and latent heat flux (LE) over a drip-irrigated olive (cv. Arbequina) orchard located in the Pencahue Valley, Maule Region, Chile (35˝25 1 S; 71˝44 1 W; 90 m above sea level). For this study, a helicopter-based unmanned aerial vehicle (UAV) was equipped with multispectral and infrared thermal cameras to obtain simultaneously the normalized difference vegetation index (NDVI) and surface temperature (T surface ) at very high resolution (6 cmˆ6 cm). Meteorological variables and surface energy balance components were measured at the time of the UAV overpass (near solar noon). The performance of the RSEB algorithm was evaluated using measurements of H and LE obtained from an eddy correlation system. In addition, estimated values of Rsi and Rn were compared with ground-truth measurements from a four-way net radiometer while those of G were compared with soil heat flux based on flux plates. Results indicated that RSEB algorithm estimated LE and H with errors of 7% and 5%, respectively. Values of the root mean squared error (RMSE) and mean absolute error (MAE) for LE were 50 and 43 W m´2 while those for H were 56 and 46 W m´2, respectively. Finally, the RSEB algorithm computed Rsi, Rn and G with error less than 5% and with values of RMSE and MAE less than 38 W m´2. Results demonstrated that multispectral and thermal cameras placed on an UAV could provide an excellent tool to evaluate the intra-orchard spatial variability of Rn, G, H, LE, NDVI and T surface over the tree canopy and soil surface between rows.

“…Summer is the period when irrigation water can best be conserved with least reduction in fruit and oil production (Goldhamer 1999), but the timing and intensity of deficit irrigation during that time has yet to be established. Previous studies have evaluated deficit irrigation during both summer and autumn, and found that deficit irrigation affects oil synthesis (Gucci et al 2007;MartinVertedor et al 2011;Moriana et al 2003;Motilva et al 2000;Patumi et al 2002).…”

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%.
