Description	Spectroradiometric methods are widely used to evaluate canopy variables like above ground biomass or canopy chlorophyll content from remotely sensed spectral data. The aim of this study is obtaining a successful model for optimizing N doses without reducing wheat yield. In this study we described the methods associated with the estimation of canopy characteristics from ground truth measurements. By using the portable device FieldSpec Hand Held 2 the spectral reflectance of winter wheat crop stands in visible region (400-700 nm) and near infrared (700 to 1000 nm) spectrum was measured at Experimental station of Mendel University in Brno located in Žabčice during different growth phases in 2013. The preliminary results showed that both parts of spectrums are sensitive to changes of crop parameters. The reflectance of crop stand under good nutritional condition increased clearly increased in the visible region and increased in the near infrared region. A further research is needed to study the relationships between the reflectance and crop parameters for correct interpretation of spectral properties of winter wheat.
