                         The test site was the sugarcane plantations of the Lencois 
                         Paulista municipality in Sao Paulo State, Brazil. Production data 
                         for four crop years were analyzed. Yields (tons of stalks/ha)of 
                         the first crop year (1983/84)were regressed against spectral and 
                         agrometeorological data of that same year and used to predict the 
                         yield the following crop year, i.e. 1984/85. The models to predict 
                         the yield in subsequent years (up to 1987/88)were developed 
                         similarly, incorporating all previous years data. The yield 
                         estimations obtained from thse models explained 69, 54 and 50 of
