The optimisation of water use efficiency in commercial fruit growing is important. Detection of the leaf coverage at tree level provides information about the growth capacity and enables estimation of the possible yield or the influence of reduced water supply in an orchard. Detection must be performed in an automated mode that may be achieved by means of two optical approaches: NIR image analysis with the calculation of the leaf coverage within the image versus the non-covered area, and counting the number of laser-scanner hits per tree. Results showed good Pearson correlation between both systems (0.917) and with two manual reference measurements (from 0.703 to 0.867).
