Abstract

Using the Eddy Covariance-sap flow method, significantly higher values of ET and reduced values of sap flow were measured during sprinkler irrigation over a mature cotton crop. The major components of total evaporation are canopy evaporation during irrigation and residual canopy interception. The measurements show that canopy evaporation is the dominant component of the total ET during sprinkler irrigation followed by canopy interception, while soil evaporation is negligible when the canopy is closed.
