Assessing plant water status from infrared thermography for irrigation management

Research was conducted in the vineyard grown in artificially transformed karst terrain (Croatia). The experimental design included four irrigation treatments in three replicates. Temperature measurements were carried out using an infrared thermal imaging camera. Biological properties, such as the leaf water potential (LWP) were also measured. The obtained crop water stress index (CWSI) values and the measured LWP values were used to create multiple regression models. It was concluded that if an automatic thermal imaging method which produced thermal images of sufficiently high quality is used, then the automatic method for the calculation of CWSI developed here is confidently applicable.
