Abstract
An energy balance equation was used to estimate evapotranspiration in a greenhouse, and an instrument for this purpose was developed. It was found that the present method is simpler than that using the Penman-Monteith equation and the estimated values by this method were in good agreement with measured data. It is also reported that normal radiation sensor measurements on a horizontal surface are not adequate for measuring radiation received by a plant canopy in a greenhouse.
