Effects of partial root-zone drying and deficit irrigation on yield, irrigation water-use efficiency and some potato (Solanum tuberosum L.) quality traits under glasshouse conditions

Agriculture water resources are expected to decline due to increasing water demand and ongoing climate change. In this context, water-saving irrigation techniques, such as partial-root zone drying (PRD) and deficit irrigation (DI) were assessed under glasshouse conditions on potato cultivar Mondial. Four irrigation levels were applied: 50, 70, 80 and 100% of field capacity during 2016 and 2017 growing seasons. The results showed that the yield...
