For Mexico it is fundamental to apply precise agricultural techniques in the sugarcane industry based on basic meteorological data such as precipitation, temperature and evapotranspiration in order to obtain the potential soil humidity, along with remote sensing techniques and the Normalized Difference Vegetation Index (NDVI). This study was performed during the 2008-2010 harvest seasons in the Huasteca Potosina region of Mexico. The analysis based on remote sensing techniques used NOAA-AVHRR images from satellites 17, 18 and 19 with AVHRR bands 1 (pi) (0.58 to 0.68 pm - red) and AVHRR 2 (p2) (0.72 to 1.10 pm - Near Infrared) to generate NDVI images. Simultaneously meteorological data was calculated based on data from from 11 agroclimate stations located in the study region. This data was, in turn, used to calculate the Water Requirement Satisfaction Index (WRSI). Results show a correlation between NDVI values and climatic conditions, which influence sugarcane productivity in the Huasteca Potosina region.
