Abstract: The hyperspectral remote sensing has greatly improved the efficiency of remote sensing technology, which incidentally proved to be appropriate to analyse large areas according to different quantity and quality parameters in a fast and economic way. Hyperspectral technology can be fitted exquisitely in the agricultural production, in the environment protection and in several other industrial applications according to quantity and quality evaluation methodology. In the following experiment we are analysing different nutrition levels of the ‘Alföld 90’ winter wheat variety using field spectroradiometer in the wavelength of 350 and 2500 nm. In the experimental arrangement different nutrition levels were applied on 10 m2 plots which were studied according to quantity and quality parameters. The treatments were carried out in agronomic replicated blocks. In order to identify the correlations, beyond the spectral analysis we evaluated plant height (cm), ear size (cm), yield (kg/10m2) and quality parameters to make comparative examinations.
