The use of information obtained by remote sensing has been suggested to model the behavior of crops through the use of vegetation indices (IV) due to its qualities spatial sampling, temporal and radiometric. In this study, we examined the growth cycle of Sugarcane using a traditional IV and spectral information in the near infrared region (NIR) to check its use as a tool for monitoring the state of development. In the development of work we employed a set of 25 satellite images ETM + sensor, with information in the spectral region of the NIR and Red (R). The imagery covered temporally the end of one season and all of the next season. The results showed a similar behavior between NDVI and reflectance of the NIR by relating to the state of development of the crop in clear sky conditions. Furthermore, with analyzed information derived, it was found that the utility of NDVI decreases when cloudiness problems occur even in small amounts, while the reflectance information from NIR band can be used for purposes of modeling development cultivation under these conditions. We conclude that the NIR information can be used reliably even in cloudy conditions for modeling the state of development of sugar cane cultivation.
