Objectives:
- Assess conventional irrigation management using automated stem psychrometers
- Monitor concurrent environmental conditions (esp. VPD)
- Analyze and correlate cumulative water potential and vapour pressure deficit (VPD) integrals
- Determine preliminary thresholds of plant water stress for irrigation management
