To estimate the actual evapotranspiration for any plant, it is necessary to calculate reference evapotranspiration (ETo), because it gives an indication of the plant water requirement to complete its life cycle. Reference evapotranspiration was calculated using 4 models and compared with FAO-56Penman-Monteith (PM) depending on weather data collected from an in-situ meteorological station at Buariydah, Qassim region, Saudi Arabia. Predictions of the four models were compared with the PM prediction by using the Mean Absolute error and correlation analysis. From the four equations used, the Jensen Haise equation gave the closest prediction to PM prediction and it was the most consistent equation in the predictions throughout the year. The Baney-Criddle equation also gave prediction close to the PM prediction but the error in its predictions was greater in summer than in winter. Both Hargreaves and Samani and Thornthwait equations overestimated the values of ETo when compared with PM prediction.
