Response of peach trees to regulated deficit irrigation during stage 2 of fruit development and summer pruning

Abstract: Regulated deficit irrigation (RDI) during stage II of fruit development and summer pruning (watersprout removal, WSR) can be used to control excessive vegetative growth in high-density peach orchards. The dynamics of tree-light interception after the application of RDI (no irrigation during stage II) and WSR in summer were evaluated during two consecutive years. RDI and WSR treatments produced similar reductions in the percentage of light intercepted by the tree at the end of the 2-year experiment. However, it… Show more

“…Other favorable results with this technique were obtained in studies developed by GIRONA et al (1993), in peach; by DOMINGO et al (1996), in real lemon; by DICHIO et al (2007) andLOPEZ et al (2008), in pear; by PEREZ-PEREZ et al (2009), in sweet orange;and GIJÓN et al (2009), in pistachios. Not as favorable result was found by GONZÁLEZ- ALTOZANO & CASTEL (2000) by applying the technique in tangerines, where a deficit of 50% of ETc, applied at the initial stage, achieved water savings of up to 23%, without negative effects on productivity and fruit quality, however, when the deficit lasted until the finals stages, besides the quality, the productivity fell about 22% for a water saving of up to 54%.…”

“…Although previous authors analyzed the effect of water deficit on fruit growth (Chalmers et al, 1981;Li et al, 1989;Boland et al, 1993;Naor et al, 1999;Goldhamer, 1999;Lopez et al, 2008), the results were not always conclusive, probably, because of different experimental conditions (soil and climatic conditions, genotype etc). Soil depth and soil water holding capacity have been reported as interacting factors in the success of RDI (Behboudian and Mills, 1997).…”

“…The success of RDI strongly depends on the appropriate use of microirrigation techniques, which allows the control of soil water content (Dichio et al, 2007). RDI has been used successfully maintaining yield and fruit quality in many fruit species (Ebel et al, 1995;Girona et al, 2003;Buendía et al, 2008;López et al, 2008), nut species Goldhamer and Beede, 2004;Romero et al, 2004;Girona et al, 2005) citrus species (Sánchez-Blanco et al, 1989;Castel and Buj, 1990;Domingo et al, 1996;Castel, 1999, 2000;Goldhamer and Salinas, 2000), wine grapes (Bravdo and Naor, 1996;McCarthy et al, 2002) and olives (Moriana et al, 2003). The most important research studies related to the application of RDI strategies in apricot trees has been done by RuizSanchez et al (1999RuizSanchez et al ( , 2000bRuizSanchez et al ( , 2004RuizSanchez et al ( , 2007, and Pérez-Pastor et al (2004).…”
