“…When comparing irrigation treatments, significantly lower Ø eq , skin chroma, and juice content were observed in stressed fruits than in well-irrigated fruits in both cropping conditions and harvest dates ( Table 4 ). The effect of soil water deficit conditions on fruit quality has been widely reported in deficit-irrigated orange and mandarin trees [ 45 ] or peach fruits [ 46 ]. In our study, withholding irrigation decreased juice content ( Table 4 ), as reported by Conesa et al [ 18 ], who observed reductions of up to 8% in juice content of deficit irrigated mandarin trees.…”

The aim of this study was to test the combined effect of water stress and cropping system on yield and fruit quality in Bearss lime trees. For this purpose, two irrigation treatments were applied during stage II of fruit growth: control (well irrigated, automatically managed by soil water content sensors) and stress (non-irrigated), both under open-field and shaded conditions. Soil water status was assessed by determining soil water content and plant water status by measuring stem water potential (Ψstem), stomatal conductance (gs), and net photosynthesis (Pn). Yield parameters (kg and the number of fruits per tree and fresh mass per fruit) and fruit quality were assessed on two harvest dates. In addition, on the second harvest date, the content of metabolites and nutrients in the lime juice was analyzed. The results showed that soil water deficit induced 35% lower gs values in open-field than in shaded conditions. The highest kg and the number of fruits per tree were observed in the shaded system, especially on the first harvest date. The lowest yield was observed in stressed trees grown without netting. Slightly higher fresh mass and equatorial diameter were observed in shaded fruits than in open-field fruit. Soil water deficit increased fruit total soluble solids and decreased juice content, especially in open-field trees. Shaded conditions made the lime trees more resilient to soil water deficit, which led to higher yields and better external fruit quality traits. In addition, fruit precocity was significantly higher in the shaded system.

“…In recent years, the related research on RDI had been gradually increased and enriched, and it had been tested or applied in a variety of crops. Such as citrus (Gonzalez-Dugo et al 2018 ; Romero-Trigueros et al 2017 , 2020 ), grape (da Silva et al 2018 ; Guo et al 2021 ; Ju et al 2019 ), blueberry (Keen and Slavich 2012 ; Lobos et al 2016 ), pear (Lepaja et al 2018 ; Wu et al 2020 ), mango (Dos Santos et al 2016 , 2020 ), peach (Falagan et al 2016 ; Manuel Miras-Avalos et al 2016 , 2017 ), melon (Lamaoui et al 2018 ; Zeinalipour et al 2017 ) and other fruits, as well as tomato (Bogale et al 2016 ; Coyago-Cruz et al 2019 ; Hooshmand et al 2019 ; Wang and Zhang 2014 ), lettuce (Chang et al 2021 ; Lin et al 2020 ), sugar beet (Abyaneh et al 2017 ; Li et al 2019 ), cauliflower (Abdelkhalik et al 2019a ; Hachmann et al 2019 ), pepper (Abdelkhalik et al 2020 ; Yang et al 2018 ), potato (Xie et al 2012 ) and other vegetables. Some food crops such as wheat (El-Sanatawy and Zedan 2020 ; Ma et al 2019 ; Zhang et al 2021 ), maize (Ma et al 2016 ; Salem et al 2021 ) and horticultural flowers such as marigold flower (Yasheshwar et al 2017 ) also had related studies on the application of RDI.…”

“…Citrus was one of the main fruits used in RDI. According to the research of Gonzalez-Dugo et al, researchers conducted RDI treatments on 2 varieties of citrus, which could save water by 50 to 55% without any impact on yield (Gonzalez-Dugo et al 2018 ). It was confirmed that the application of RDI could reduce the loss caused by fruit cracking, and reduce the oversized fruits, so as to improve the commercial yield of citrus by optimizing the distribution of fruit size without affecting the sensory quality.…”

Regulated deficit irrigation: an effective way to solve the shortage of agricultural water for horticulture

The deficient agricultural water caused by water shortage is a crucial limiting factor of horticultural production. Among many agricultural water-saving technologies, regulated deficit irrigation (RDI) has been proven to be one of the effective technologies to improve water use efficiency and reduce water waste on the premise of maintaining the quality of agricultural products. RDI was first reported more than 40 years ago, although it has been applied in some areas, little is known about understanding of the implementation method, scope of application and detailed mechanism of RDI, resulting in the failure to achieve the effect that RDI should have. This review refers to the research on RDI in different crops published in recent years, summarizes the definition, equipment condition, function, theory illumination, plant response and application in different crops of RDI, and looks forward to its prospect. We expect that this review will provide valuable guidance for researchers and producers concerned, and support the promotion of RDI in more horticultural crops.

“…This is because a crop in a healthier soil will be transpiring and consuming more water because it experiences more soil-water as "freely available soil moisture." The corollary also applies; degraded soils with lower RAM are more likely to present crops and farmers with higher soil moisture stress and poor hydraulic conductivity that together reduce plant transpiration (Bodner et al, 2015;Gonzalez-Dugo et al, 2018). • Additionally, considering the whole irrigated system, interventions to "use less water" at the field or farm scale can result in an overall increase in basin water consumption (Ward and Pulido-Velázquez, 2008;Grafton et al, 2018).…”

This article seeks greater clarity in the connections between water and regenerative agriculture (RA). We first review existing soil/water knowledge and argue that desired “RA and water” outcomes depend on the management and optimal levels of two key soil properties; readily available moisture and infiltration rate. Secondly, we hypothesize these help define a range of RA beneficial outcomes or “promises,” such as improved vegetative growth, reduced risk of erosive runoff, higher soil organic matter content and biological fertility, easier irrigation management, resilience to drought, better water filtration and less variable streamflow hydrology. Thirdly we show that by not fully understanding water's multiple roles for achieving desired RA outcomes, risks, contradictions and “pitfalls” can arise. With these three parts we observe that carefully explained and quantified roles of water in the existing RA literature are often missing, neglected, over-generalized or poorly explained. We also suggest that narratives and terms (e.g., “net zero” or “net positive”) for describing the benefits and aims of RA and water can lack context and situational fit, or are misleading and incorrect. Cautions also apply to water quantities additionally required for soil regeneration activities, recognizing stiff competition for scarce river basin water and its allocation. How necessary quantities overlap with local and catchment policies for water allocations and hydrology, incorporating farmers' views and choices and informed by field, farm and system water accounting, are critical to successful agricultural practices including those that are “regenerative.” Accordingly, we suggest that scientists and decisions-makers should more thoroughly interrogate how “RA and water” is being analyzed so that relevant policies develop its promises whilst avoiding pitfalls.
