Existing vine water status monitoring tools are often complex and expensive. Shoot growth observations have been demonstrated to be an interesting alternative for field-level management but not yet at the within-field scale. The study reported in this paper was conducted to determine whether a simple shoot observation method could be satisfactorily used to characterize the spatial structure of shoot growth related to water stress at within-field scale. Based on a geostatistical approach, this study showed that shoot growth observations can be used to delineate within field management zones of vine water status if observations are made by a single operator and during periods when vine water stress is increasing.
