The estimation of crop phenology is necessary to grasp the water use of irrigated farmlands. To estimate the crop phenology, time-series patterns of Leaf Area Index (LAI) are considered effective. A method is proposed for extracting LAI time-series patterns by calculating the difference between vegetation coverage estimated in visible bands and visible + near-infrared bands. The method proved to be more suitable for the estimation of LAI time-series patterns than conventional vegetation indices.
