Application of multispectral remote sensing indices for estimating crop yields at field level

Original language description

Remote sensing can be used for yield estimation prior to harvest and can replace or complement classical ways of estimating crop yields. This study was undertaken in Polkovice, located in the Czech Republic&apos;s Haná region. For 2015 and 2016, two data sets of satellite imagery were used: the Moderate Resolution Imaging Spectroradiometer and the Landsat 8. Vegetation indices from satellites were compared with crop yields at the level of land blocks. Winter wheat and spring barley yield data, representing crops planted over the analysed period, were used for the comparison. The results of the index-yield comparison showed that vegetation indices from remote sensing data provide reliable information for yield estimation prior to harvest. Indices are also able to evaluate the spatial variability of a crop within the field. The results showed that remote sensing data need to have detailed spatial resolution in order to provide reasonable information about yield at such a detailed level.
