Narrow band spectral indexes for chlorophyll determination in soybean canopies [Glycine max (L.) Merril] Braz. J. Plant Physiol.
Ferri,Clotilde Pinheiro; Formaggio,Antonio Roberto; Schiavinato,Marlene Aparecida.
Photosynthetic pigments are essential for plant development. Quantifying these pigments in great extensions of agricultural crops is an important objective in remote sensing for agricultural purposes. This information can be used to produce a more accurate estimation of the physiological state of the vegetation, for species discrimination and productivity estimation. The aim of the present study was to (a) evaluate the potential for estimating chlorophyll content of crop canopies, using narrow band spectral indexes, and (b) in this respect compare the performances of NDVI (a multispectral wide band index) and two narrow band vegetation indexes (R750/700 and R750/550). Experiments were carried out under greenhouse conditions whereby soybean [Glycine max...
