This study evaluates the influence of rainfall, southern oscillation index (SOI), multivariate index of El Niño Southern Oscillation (ENSO), sea surface temperature anomaly of the sea surface (SSTA) in the Atlantic dipole index and normalized difference vegetation (NDVI/derived from satellites METEOSAT 9 and 10) on agricultural productivity of cane sugar (ton/ha) on the southern coast of the State of Alagoas for the period 2000-2005. Analyses were performed using rainfall Coruripe Plant, located in the municipality of Coruripe/AL. The results show that the annual variability of the agricultural productivity of cane sugar mill Coruripe is modulated largely by rainfall. Additionally, characterized and interannual variability annual agricultural productivity of cane sugar related to climate variability. The results also suggest that the NDVI data from the satellites METEOSAT 9 and 10 used in this work, proved to be, useful observations to characterize the agricultural productivity of cane sugar mill Coruripe.
