Regulated deficit irrigation (RDI) and partial root zone irrigation (PRI) were compared for four years (2009–2012), each at two different irrigation volumes (110 mm year−1 (1) and 78 mm year−1 (2)), in fieldgrown Monastrell grapevines grafted onto 1103P, in South Eastern Spain. The aim was to distinguish the effects of deficit irrigation per se from specific PRI effects (placement of water) on yield response and berry and wine quality. Vines grown with PRI-1 or RDI-1 received around 30% of the ETc from budburst to fruit set, 13–15% ETc from fruit set to véraison and 20% ETc from véraison to harvest. The RDI-2 and PRI2 vines received around 20% ETc from budburst to fruit set, no irrigation from fruit set to véraison and a recovery (21-24% ETc) thereafter. In general, the PRI-2 and RDI-2 vines (the most-severely water-stressed) showed greater yield reduction and lower overall berry and wine quality (including technological and phenolic composition) than the moderately-water-stressed vines (RDI-1 and PRI-1). Compared to RDI-1,

PRI-1 improved the yield response—increasing mean yield, cluster number per vine and berry weight and maintaining better bunch health at late ripening and a greater proportion of bigger bunches. In addition, PRI-1 increased the anthocyanin and amino acid concentrations of the berries and altered their composition, improving the phenolic and chromatic characteristics of the wine and enhancing the healthpromoting value of the fruit. It was also the option most economically viable under the present conditions of the wine grape market, compared to RDI-1 and the rest of the treatments. In contrast, PRI-2, although it improved some technological quality attributes and phenolic and chromatic characteristics of Monastrell berries and wines compared to RDI-2, did not have a positive effect on yield (yield and cluster and berry weight decreased in some years) and its implementation was economically unviable under these soil and climatic conditions. The significant interaction between irrigation volume (high vs. low) and irrigation placement (PRI vs. RDI) indicate that the response to PRI also depended on the volume of water applied in the wet root zone and the soil total water availability. © 2014 Elsevier B.V.

The latter, novel PRI effects (compared with conventional DI plants which received the same amount of water) in different species include: (1) greater fruit growth, fruit fresh weight and/or total fruit dry weight (Dorji et al., 2005; Antolín et al., 2006; Zegbe et al., 2007; Spreer et al., 2007; Topcu et al., 2007; Aganchich et al., 2008; Savic et al., 2008; Talluto et al., 2008; Senyigit and Ozdemir, 2011; Romero and Martínez-Cutillas, 2012); (2) increased soil N availability, improved fertilizer-N use efficiency and plant N nutrition and distribution in the canopy (Wang et al., 2009, 2010, 2012a–c;
