“…Plants did not show a clear response when irrigation ranged between 100% and 70% of ETc. These results were similar to those obtained by Martín-Vertedor et al (2011), in which adult olive plants that were irrigated to meet 100% of their transpiration demand showed more growth, but a slight water restriction did not affect growth. It has been shown that the growth magnitude of each plant is strongly related to the amount of water applied and its subsequent water status .…”

“…However, during the second growing season, pomegranate trees had a lower capacity for tolerating water restrictions (Melgarejo, 2001;Bhantana and Lazarovitch et al, 2010). Similar results were found for olive and cherry trees (Martín-Vertedor et al, 2011;Livellara et al, 2011), but there were no effects of irrigation regimes on canopy volume in peach trees (Pérez-Pastor et al, 2014). This study showed that canopy growth was at a maximum when soil watering was equivalent to 100% or 130% of evapotranspiration (ETc).…”

“…For T 130 and T 100 , p-values were less interfering directly with the development of new shoots and canopy expression (Nortes et al, 2005). A defi cient water regime during the fi rst stages of growth could completely inhibit vegetative development, depending on the age of the plant (Martín-Vertedor et al, 2011). This effect is attributed to a reduction in stomatal conductance, transpiration and photosynthesis, and the subsequent decreased growth of young plants (Intrigliolo et al, 2011a).…”

“…A thick trunk (a characteristic of the Lythraceae family) allows this tree to maintain water during long periods of shortage . However, water restrictions limit the growth of new buds, shoots and trunks, in young and adult plants (Moriana and Fereres, 2002;Martín-Vertedor et al, 2011).…”

. We evaluated the effect of the four treatments on canopy volume (CV) during two growing seasons. For 28 days during the second growing season, we evaluated soil moisture content (θ), the soil-moisture depletion factor (p), trunk cumulative growth (TCG), trunk growth rate (TGR) and maximum daily trunk shrinkage (MDS). We found relationships between CV and TCG and between CV and TGR. There were no differences in MDS among the irrigation treatments. We observed significant water stress in plants in the 0.3 ETc treatment (p = 0.47). The highest growth was observed in plants in the 1.3 ETc treatment, which suggests that the crop coefficient (Kc) was underestimated.

“…These water stress indicators have also their limitations. According to Martín-Vertedor et al (2011) and Fernández (2014a,b), leaf or stem water potential measurements are good indicators of olive water status, but they are not suitable for precision agriculture because they cannot be automated. In fact, their use is based on destructive, non-continuous, high labour-and time-consuming measurements.…”

a b s t r a c tWater scarcity is the most limiting factor in many irrigated areas of Mediterranean countries such as South Spain. Olive growing has been traditionally associated to rain-fed agriculture, although irrigation and practices related to intensive agriculture have been progressively introduced, requiring a more precise irrigation scheduling to save water. Thermal imaging is among the alternatives to assess the crop water status, especially when deficit irrigation (DI) strategies are applied. However, this technique requires of new advances to be more user friendly and robust for practical usage. The aims of this study were: i) to define threshold values of canopy temperature (T C ), Crop Water Stress Index (CWSI) and the temperature difference between canopy and the surrounding air ( T canopy-air ) for the assessment of the olive water status when a DI strategy is applied; ii) to define the best time of the day and the best area of the canopy to carry out thermal measurements, and iii) to obtain relationships between thermal indicators and main physiological parameters useful to estimate the crop water status from thermal data. The trial was conducted during 2015, in a hedgerow olive orchard (SW Spain) with 8-year-old trees (Olea europaea L., cv. Arbequina), under three irrigation regimes: a full-irrigation treatment (FI) and two regulated deficit irrigation treatments aimed to supplying 45% of the irrigation needs. In one of them, irrigation was scheduled from leaf turgor pressure related measurements (45RDI TP ). In the other, the crop coefficient approach was used to schedule irrigation (45RDI CC ). Significant correlations between Tc versus stem water potential (« st ) and leaf gas-exchange parameters (stomatal conductance to water vapour, g s ; net CO 2 assimilation, A N ; transpiration, E) were obtained (p ≤ 0.05), in particular from measurements taken at 10:30 GMT in the lower part of the sunlit side of the canopy. Moreover, the relationships between both T canopy-air and CWSI with the monitored physiological variables were very robust. We concluded that values of T canopy-air higher than 0 • C and values of CWSI up to 0.2 reliably reflect the plant water stress. Our results, therefore, suggest that both T canopy-air and CWSI measured at midday provide reliable information on the tree water status and are useful to schedule irrigation in hedgerow olive orchards, especially under DI conditions.

In this study, six different irrigation treatments were applied to an olive orchard using the drip irrigation method. Five of these were arranged according to 25% (S0.25), 50% (S0.50), 75% (S0.75), 100% (S1.00) and 125% (S1.25) of the evaporation in 5 days of a class ‘A’ evaporation pan, and one control (SC) was arranged so as to bring the reducing moisture at a soil depth of 0–90 cm to field capacity. Yield values were not affected by the irrigation treatment (p > 0.05). In contrast, 100‐fruit weight, pulp ratio, hardness moisture, oil, reducing sugar content and bitterness were affected by irrigation (p < 0.05). Generally, an increase in the amount of irrigation water given in the study was accompanied by a fall in ripeness index values, a rise in moisture content, and a reduction in the oil content of fruit. The highest content of reducing sugar was obtained from S0.25, generally being lower with increase in the water applied. The findings show that application of 25% of the evaporation of a class ‘A’ evaporation pan (treatment S0.25) can be recommended for cv. Memecik. Application of this recommendation can achieve a 72% saving in water and make a significant contribution to the conservation of limited water resources. Copyright © 2017 John Wiley & Sons, Ltd.
