Comparison Methods of Estimation Potential Evapotranspiration for Oil Palm

Abstract

The estimation of potential evapotranspiration constitutes an important part in the evaluation of climate.  Many methods exist and all of these are indirect methods using equations that relate climatic data with evapotranspiration.  A comparison of the three methods to estimate crop evapotranspiration being the method of Jabatan Parit dan Saliran (1977), Doorenbos and Pruitt (1977) and Penman- Monteith (Smith, 1991). Results showed that the method of Doorenbos and Pruitt (1977) provides a fairer estimation of evapotranspiration for oil palm cultivation in Peninsular Malaysia
