“…PRD is now being imposed on an expanding list of crop species with frequently observed improvements in water‐use efficiency, little reduction in yield and improvements in crop quality over RDI (e.g. tomato, Solanum lycopersicum , Kirda et al ., ; grapevine, Vitis vinifera , Romero et al ., ; potato, Solanum tuberosum , Liu et al ., ; cotton, Gossypium hirsutum , Tang et al ., ), but not universally (Sadras, ). The improvements in horticultural crop quality through PRD and RDI occur through stress‐induced increases in secondary metabolite content, which are known contributors to quality in fruits such as grape and tomato (Davies et al ., ).…”

SUMMARYPlant breeding and improvements in agronomic practice are making a consistent contribution to increasing global crop production year upon year. However, the rate of yield improvement currently lags behind the targets set to produce enough food to meet the demands of the predicted global population in 2050. Furthermore, crops that are exposed to harmful abiotic environmental factors (abiotic stresses, e.g. water limitation, salinity, extreme temperature) are prone to reduced yields. Here, we briefly describe the processes undertaken in conventional breeding programmes, which are usually designed to improve yields in near-optimal conditions rather than specifically breeding for improved crop yield stability under stressed conditions. While there is extensive fundamental research activity that examines mechanisms of plant stress tolerance, there are few examples that apply this research to improving commercial crop yields. There are notable exceptions, and we highlight some of these to demonstrate the magnitude of yield gains that could be made by translating agronomic, phenological and genetic solutions focused on improving or mitigating the effect of abiotic stress in the field; in particular, we focus on improvements in crop water-use efficiency and salinity tolerance. We speculate upon the reasons for the disconnect between research and research translation. We conclude that to realise untapped rapid gains towards food security targets new funding structures need to be embraced. Such funding needs to serve both the core and collaborative activities of the fundamental, pre-breeding and breeding research communities in order to expedite the translation of innovative research into the fields of primary producers.

“…Results of Antolín et al (2006Antolín et al ( , 2008 showed that under PRD changes in ABA content improved berry quality by increasing anthocyanin content and that increased mRNA induced accumulation of genes responsible for anthocyanin biosynthetic pathway (Jeong et al, 2004). According to Romero et al (2016) reduced vegetative growth and increased light penetration into the canopy in PRD vines together with the increased ABA content and salicylic acid (in berries at harvest) might have an increasing effect on production of phenolic compounds which have a different roles (as antioxidants, stabilizators of anthocyanins, for wine color, etc). The same study reported that elevated amino acids concentration was also associated with their role as antioxidants and osmoprotectants as well as precursors for the synthesis of some aromatic substances important for the taste of wine.…”

Due to climate changes and increased demands of different water users (agriculture, industry, domestic) water becomes scarce resources worldwide. Since irrigated agriculture is the one of the largest consumer of these resources (so-called blue water footprint), irrigation management must be shifted from maximal production per crop area to maximal production per unit of water used by crops. Among the strategies for reducing water footprints, changing the full irrigation to the reduced crop's water supply (deficit irrigation techniques) is one of the options. In this mini-review, we present the latest advances of partial root-zone drying (PRD) applications in different agricultural plants, with the special emphases on the PRD effects on increasing WUE, yield and yield quality. We describe two PRD practical approaches (alternate and fixed), background of PRD induced increase in yield and water use efficiency and improved understanding about nutrient use efficiency. The evidence of PRD effect on the increase in nutritional and health attributes of yield in different species is also presented. Because of limited available data, further research is needed to understand complex biosynthetic pathway and synthesis of nutritive-and health-related metabolites and antioxidants in PRDtreated plants. Practical application and promotion of this knowledge will allow farmers in water scarce areas to adapt PRD not only as a strategy for saving water, improving nutrient use and increase/sustain yield, but also for producing food with enhanced nutritive and health characteristics.

“…There were no differences between the last two treatments. Under water stress, the grapes were normally smaller due to lower availability of water for cellular elongation (ROMERO et al, 2016), which reflected in the lower weight of bunches. Bassoi et al (2011) showed that the water deficit generally results in smaller grapes and modifies the mineral composition of the fruit, then corroborating the results from this study.…”

“…On the other hand, the increased sugar concentration was due to the dehydration in some of the grapes in the bunch, and the reduced bunch weight was a result of the lower water supply by the treatments DI and RDI. This is a consequence of the increased skin/pulp ratio, which is favored by a low availability of water for cellular elongation (ROMERO et al, 2016;PEYNAUD, 1997). The treatments that led to lower weight in grape bunches (DI and RDI) were those that had higher alcohol values in the wines ( present work (Table 2) are within the values established by legislation, which allows variation between 4.12 and 9.75 g L -1 of tartaric acid (BRASIL, 2004).…”

Deficit irrigation is used to control grapevine vegetative vigor and the grape composition can be influenced by soil water content. The minerals contained in the grapes are responsible for the physicochemical properties and stability of the wine. Therefore, the aim of this work was to evaluate the effects of irrigation strategies on the properties of 'Syrah' wines produced in São Francisco Valley, Brazil. The irrigation treatments used were FI (full irrigation), RDI (regulated deficit irrigation), and DI (deficit irrigation). Winemaking was performed by traditional methods, followed by stabilization and bottling. Density, alcohol content, pH, total and volatile acidity, total and free sulfur dioxide, total polyphenols index, color intensity, and total anthocyanin content were determined, as well as the contents of Ca, Mg, P, K, Na, Mn, Fe, Cu, Zn, Cd, Cr, Ni, and Pb. The properties of wines were influenced by irrigation strategies, except for the content of total anthocyanin, Mg, P, Na, Cu, and Mn. The contents of Cd, Cr, Fe, and Zn were similar in the vines. The wines demonstrated varied properties with different typicalities. Irrigation strategies can be recommended for different products, FI for young and cheap, and DI and RDI for aged and more expensive wines.
