To estimate the production of aerial biomass of crops using remote sensing, the production of biomass and spectral data in five crops measured in the field were analyzed during a sampling campaign in the Valle del Yaqui, Sonora. The spectral information was processed to obtain the vegetation iso-soil index (IVIS). Multitemporal analyses show a similar response between crop development and IVIS, and a linear relationship was obtained between them. Similarly, the harvest index and its relationship with IVIS were analyzed. The results showed that IVIS is a suitable index for estimating biomass and yield in crops.
