Context and purpose of the study: Water and heat stress impose new challenges to irrigation management
in the Mediterranean areas. This reality has a major impact on the vineyard ecosystem, particularly on the
scarce water resources of the Alentejo region (South Portugal). To mitigate this problem, irrigation
management should focus on optimizing yield and fruit quality per volume of water applied. This work aims
to discuss the use of predawn leaf water potential and soil water status relationships as a decision tool for
irrigation management taking as basis data from a field trial where two deficit irrigation strategies were
