Health condition and vegetation activity are very important indicators to know the primer production of plants and fruit trees as well. There is a very close relationship between the dynamism of fruit tree development and their photosynthetic activity. Some traditional and modern instruments and methodology were used to survey vigor condition of the vegetation. We surveyed an intensive apple orchard at the Regional Research Farm of the University of Debrecen near Pallag by three spectral instruments. The spectral surveys were at the early senescent stage of the apple plantation. Investigation results were analyzed by different software environments; normalized differential vegetation index (NDVI) map was created and spectral point sampling was carried out in the test site. Spectral results were compared and strong linear correlations (r>0.7) were detected between each spectral measurement. The applied instruments gave information about vigor condition of the fruit trees in a non-destructive way.
