Abstract

Environmental issues such as prolonged drought have triggered the need to reduce the use of irrigated water to a sustainable level. Novel irrigation methods, like partial rootzone drying (PRD), have increased our understanding of plant physiology with respect to plant water use. A field trial was established in Mildura, Northwest Victoria, Australia to determine whether Vitis vinifera L. cv. ?Shiraz? grown in semiarid conditions were actually producing a PRD response, that being a reduction in stomatal conductance with no loss in plant water potential, and then to measure the responses with respect to yield and fruit quality attributes. Treatments consisted of a control irrigated by two drip..
