Fruit Yield and Quality of ‘Valencia’ Orange Trees under Long-Term Partial Rootzone Drying

Abstract: Climate, soil and tree water status, fruit yields and quality of ‘Valencia’ orange trees were monitored over five consecutive seasons (2007–2012) to study the effects of irrigation placement or volume. Three irrigation treatments were imposed: conventional irrigation (CI, 100% of crop evapotranspiration on both sides of the rootzone), partial rootzone drying (PRD, 50% of CI water only on one alternated side of the rootzone) and continuous deficit irrigation (DI, 50% of CI water on both sides of the rootzone). … Show more

“…Compared to severe RDI with water supply of 35% of ETc, a moderate RDI with water supply of 50% ETc from mid-July to mid-September, can successfully be applied to 'Clementina de Nules', allowing a 15% water saving without any detrimental effect on tree performance or economic return [72]. The PRD strategy applied to orange trees with 50% ETc resulted in a significant water saving, with no negative effect on fruit yield, and was concluded to be sustainable for orange orchards [44][45][46]75]. Variety and rootstock genotypes are reported to play a significant role in tree response to water deficit [36,37].…”

“…Irrigation strategies such as controlled deficit irrigation (CDI) and partial rootzone drying (PRD) have been evaluated in citrus, and in both cases, the results showed water saving but a significant decrease in yield and fruit quality [8]. In terms of the use of physical barriers to prevent water evapotranspiration, an example is the use of organic or plastic mulch over the soil to reduce water evaporation.…”
