Water requirement and water use efficiency in Eucalyptus flocktoniae (Maiden) Maiden and E. leucoxylon F. Muell

The response of plants to water available for strategy codification of water resources and irrigation is very important. In this study, evapotranspiration, crop coefficient, yield and water use efficiency in two species of Eucalyptus (Eucalyptus flocktoniae (Maiden) Maiden, E. leucoxylon F. Muell.) through lysimeter experiments were determinated under different soil moisture levels (100%, 70% and 40% of field capacity). The research was designed as a factorial experiment on a completely randomized design with three replications in Yazd climatic conditions. The results showed that with increasing soil moisture in both species, evapotranspiration increased, so that there were significant differences between the different levels of soil moisture treatments (p
