[Efecto de aplicación de agua sobre la calidad y producción de vino en Carmenere bajo la presencia de una napa freatica superficial en Chile central]

Abstract

Chile is the world’s leading producer of Carmenere (Vitis vinifera L.), which in turn is an important variety in Chile, where vineyards are typically grown under irrigated conditions and a large percentage are located in valleys with similar water table levels to those of the study area. Different irrigation management strategies have been used to improve wine quality, such as water stress and deficit irrigations, but the presence of a water table has not been considered in extant literature. This study analyzes the effects of the irrigation regime on grape yield and wine quality when a shallow water table is located between 1.5 to 2.2 m depth during the irrigation season
