Partial root-zone drying increases WUE, N and antioxidant content in field potatoes

Effect of Deficit Irrigation and Root-Zone Drying Irrigation Technique under Different Nitrogen Rates on Water Use Efficiency for Potato (Solanum Tuberosum L.) in Semi-arid Conditions (I)

“…It was concluded in the framework of this study, that PRD irrigation has saved 30% water irrigation and has improved water productivity in seasonal potatoes in the order of 60%. Similar results obtained on the potato and reported by Jovanovic et al, (2010) showed that PRD irrigation led in two successive years to irrigation water saving of the order of 33 …”

Performance of partial root-zone drip irrigation for sugar beet production in a semi-arid area

“…Water and nitrogen are essential resources for crop production, and their availability predominantly effects crop yield and quality. Crop nitrogen nutrition under the PRD irrigation technique has been tested in some crops such as maize (Kirda et al, 2005;Hu et al, 2006Hu et al, , 2009Li et al, 2007;Wang et al, 2012), potato (Shahnazari et al, 2008;Wang et al, 2009;Jovanovic et al, 2010;Li et al, 2010), tomato (Wang et al, 2013), and winter wheat (Sepaskhah and Hosseini, 2008). According to Wang et al (2009), PRD irrigation may increase not only WUE but also nitrogen use efficiency (NUE).…”

Improving potato cultivation using siphons for partial root-zone drying irrigation: A case study in the Blue Nile river basin, Ethiopia

“…the dry one is irrigated the following cycleis a promising irrigation technique that saves water (39 -50%) through increased water use efficiency (WUE) with no significant tuber yield reduction in this crop (Liu et al 2006a;Liu et al 2006b;Jensen et al 2010;Xie et al 2012;Yactayo et al 2013). The benefits of PRD in potato production are also associated with a higher marketable tuber size, soil N-availability and antioxidants in tubers (Rojas et al 2007;Shahnazari et al 2007;Shahnazari et al 2008;Jovanovic et al 2010). However, PRD is mainly performed under furrow irrigation with limited studies DOI 10.1515/opag-2017-0028 Received November 6, 2016accepted April 13, 2017 Abstract: Partial root-zone drying (PRD) is an irrigation technique which consists of alternating the water supply from one furrow to another, and keeping the other one dry during the weekly alternation period.…”
