Abstract

A GER-1500 field spectro-radiometer was used in this study in order to retrieve the necessary spectrum data of the spring potatoes for estimating the spectral vegetation indices (SVI's). A field campaign was undertaken with measurements of LAI, and crop height using the Sun-Scan instrument, acquired simultaneously with the spectroradiometric measurements between March and April of 2009. Several regression models are tested for determining the best 'regression models' that to relate LAI/crop height and SVI's. The results showed that there is a strong statistical relationship between LAI/crop height and SVI's which can be used at the estimation of evapotranspiration (ET_c). Direct comparison and validation of proposed models with Landsat image data is also made. The study area was the Mandria Village in Paphos district in Cyprus.
