Spectral signature variations as a function of bandwidth using 3 nm bandwidth observations Original Research Article

Study with 3 nm bandwidth observation in visible Near-IR spectral region revealed that 760–830 nm and 650–673 nm are optimum bands in NIR and red region for computation of NDVI over the crop growth cycle of wheat. The 760–850 nm could be used in place of 760–830 nm if high spatial resolution is needed.
