The objective of this paper is to evaluate the patterns of spectral and agronomic variables of 5 soybean varieties through developing cycle. In this it was used the bidirectional reflectance factor measured with a spectroradiometer and integrated in TM3 and TM4 bands, and vegetation indices calculated from these bands. The TM3 band decreased until reach the minimum value for the full developed crop. The TM4 band vegetation indices increased rapidly until reach the maximum value. In the final of the crop cycle they decreased in consequence of the leaf senescence. It was found that inclination characterized vegetation indices did not have a good performance in monitoring the crop along the crop cycle, because they reach the saturation for low leaf area index values. Instead, distance characterized vegetation indices showed a good performance for monitoring the 5 varieties along the crop cycle. These indices, namely PVI and WDVI, was found to be useful to separate soybean varieties. |
