Medidas da evapotranspiração em pomar de bananeiras irrigadas em Quixeré – CE com o método das correlações turbulentas.

Abstract

The evapotranspiration estimate is very important in the planning and handling of crops. The objective of this work was to determinate the daily evapotranspiration - ETC of a banana (Musa sp.) orchard in the Irrigated District of Jaguaribe-Apodi in Quixeré - CE (5º4’35”S; 37º51’54”O), using the eddy covariance method. The experiment was installed in the central part of an area with about 300 ha, at Fazenda Frutacor. The evolution of Rn, H and LE values in the three months of analyzed data was relatively equal. That might be result of the season (September 02 to November 31) and for the irrigated condition. The minimum and maximum ET measured values in the analyzed period were equal respectively to 3,2 and 4,5 mm.
