O trabalho foi conduzido em Santana do Livramento, no ciclo vegetativo de 1990/91,com o objetivo de avaliar o efeito de épocas de desfolha e de colheita sobre a composição físico-química do vinho Chardonnay. O vinhedo era conduzido em espaldeiro. com espaçamento de 3,5 m entre fileiras e 2,0m entre plantas. As plantas tinham doze anos de idade, foram enxertadas sobre o porta-enxerto S04 e podadas no sistema de cordão esporonado. O delineamento experimental utilizado foi o completamente casualizado, num fatorial incompleto, totalizando onze tratamentos, aplicados em função de quatro épocas de desfolha e três épocas de colheita, levando-se em conta uma data ideal de colheita (DIC);houve três repetições. |

ETa and irrigation were daily estimated between June, 2015 and May, 2016 by combining STARFM with SEBAL and evaluated according to the Bowen ratio technique and irrigation data.

Adding fused images resulted in a better fit of the estimated cumulative ET24 curve to the measured ET24. The water balance indicated that the cultivated cane suffered water stress, which was better represented by estimates using the ET24 curve with the addition of fused images than Landsat images alone.
