“…In general, our results agree with those presented by P erez-P erez et al (2014,2015), who reported i) a reduction in juice content by RDI, as in 2015, due to dehydration processes or internal changes in fruit structure and ii) an increase in SSC (under saline water) and in TA (under RDI and saline water). However, Pedrero et al (2015) reported no differences in SSC/TA ratio for the same orchard during 2008e2010; this is because the measurements were taken at the first 3 years of establishment of RDI and RW. Besides, fruit quality often is affected by crop load, therefore, it would be necessary to have similar crop loads in both periods to really compare fruit quality.…”

a b s t r a c tThe aim of our research was to discover the effects of the long-term irrigation with saline reclaimed (RW) and transfer (TW) water and different irrigation strategies: control (C) and regulated deficit irrigation (RDI) on yield and fruit quality of grapefruit at harvest and during cold storage. TW-RDI treatment decreased tree canopy (TC) and crop load, resulting in a 21% reduction of fruit yield. Regarding fruit quality, RW notably decreased peel thickness at harvest (about 8%); however, this difference was not remained during cold storage. Sugar/acid ratio was mainly increased by RDI, but also by RW, due to an important increase in soluble solid content (11% of average value for TW-RDI, RW-C and RW-RDI). In addition, RDI combined with RW, significantly increased the number of fruits in small category 5 at the end of cold storage. Finally, neither ratio yield/TC nor irrigation water productivity were affected by any irrigation treatments.

“…The experimental plot was cultivated with 9 year-old (since 2013) 'Star Ruby' grapefruit trees (Citrus paradisi Macf) grafted on Macrophylla rootstock spaced 6 Â 4 m. Regular irrigation was scheduled on the basis of crop evapotranspiration (ET c ) as described by Pedrero et al (2015).…”

“…The experiment was conducted in 2015 in a commercial Citrus orchard, located at the northeast of the Region of Murcia in Campotéjar (38º07'18"N, 1°13'15"'W, 132 m above sea level) with a BSk climate by Köppen-Geiger classification (Peel et al, 2007 (Allen et al, 1998), by a monthly local crop coefficient according to Pedrero et al (2015) for grapefruit and Nicolás et al (2016) for mandarin.…”

“…Irrigation water is not always available (mainly in summer) in the semi-arid Mediterranean areas due to water scarcity (Pedrero et al, 2015). Therefore, irrigation scheduling needs to be precise, and this requires strategies to optimize irrigation water productivity (Tapsuwan et al, 2014).…”

• Reclaimed water significantly reduced total chlorophyll in grapefruit and mandarin leaves. • Normalized Difference Vegetation Index (NDVI) was related to gas exchange variations. • Near infrared (NIR) and red (R) domains were the best spectral indicators for both species. • Usefulness of remote sensing for assessing diurnal changes in Citrus physiology was confirmed.

“…El efecto del empleo de AR para agricultura en el sureste de España ha sido motivo de algunas investigaciones. Pedrero et al (2015) determinaron en un huerto comercial de pomelos, que el empleo de AR no aumenta la salinidad del suelo, si bien tiene lugar un aumento de la concentración de Na, Cl y B en hoja.…”
