Assessment of the relationship between spectral indices from satellite remote sensing and winter oilseed rape yield

Popis výsledku v původním jazyce

Winter oilseed rape (Brassica napus L.) belongs among the most common and strategic crops in the Czech Republic. Growth and vitality status, yield potential and yield prediction of oilseed rape on plots of different sizes can be effectively examined using remote sensing. That is why the main aim of this study was to discuss a possibility of deriving spectral indices for an assessment which spectral index is more adequate to forecast oilseed winter rape development and consequent yield in the Czech Republic. Information about the winter oilseed rape growth and yield was collected in three years 2004, 2008, 2012. A relationship between grown crops and selected vegetation indices was evaluated. The Landsat 7 satellite images were selected as a source for deriving spectral indices. The relationship between each spectral index and yield was analysed in 2012 only. Five images on different dates during the whole life of winter oilseed rape were found during this year. The images from the years 200
