Abstract

The combination of uncertain and low water availability, the increasing cost of water for irrigators and the use of water as a lever to control yield and fruit composition has driven a need for improved irrigation scheduling in southern Australia. Remotely sensed canopy temperature assessment offers a potentially reliable and cost effective means for improving irrigation scheduling. Crop water stress index (CWSI), based on canopy temperature was assessed during berry ripening for 'Cabernet Sauvignon' exposed to deficit irrigation in central Victoria, Australia. CWSI was calculated from canopy temperature (Tc), a dry reference surface (Td) and a wet reference surface (Tw) using the method of ..
