Evapotranspiration data over a soybean field were obtained from a weighing lysimeter during 1988, when the month of July was marked by intense heatwave in Greece. Soil water contents were determined by neutron probe at regular intervals before and after irrigation. Meteorological measurements, including mean daily values of air temperature, relative humidity, wind speed, solar radiation and precipitation allowed the study of reference evapotranspiration and its comparison with class-A pan evaporimeter data during this period of extreme exposure conditions. Values of the Priestley-Taylor parameter, α, were derived and a mean value of 1.58 was found. A generalized basal crop coefficient curve was determined from the lysimetric data and the time evolution of soil moisture profiles according to Wright's procedure. A rather high peak value, 1.4, for the soybean crop coefficient was obtained. This is mainly attributed to the very high crop evapotranspiration demands during the 1988 heatwave in Greece and the differences in the method of deriving the crop coefficient and computing the reference evapotranspiration. © 1991 Kluwer Academic Publishers. |
