| Abstract: | Summary Evaluation of a modified Bellani cup atmometer was done in two steps; theoretically to verify that it can be used as a physical model of plant transpiration, secondly and empirically, four different atmometers were compared to determine the variability among different instruments and the agreement between atmometer water loss and Penman ET. Variability among atmometers was small and the response of the instrument water loss to variations in weather conditions was similar to that predicted by the Penman equation. It was concluded that the atmometer can be used to estimate reference ET for irrigation scheduling purposes. |
