520			_aResults of evapotranspiration research on the energy balance of corn and sorghum plants and their respective leaf and air temperatures are presented. The difference between crop canopy and air temperatures provides the gradient for the flow of sensible heat toward or away from a vegetal surface. Sensible heat flux toward the canopy is an important source of energy for evapotranspiration. The energy balance of corn (Zea mays L. cv. Prairie Valley) and of sorghum (Sorghum bicolor L. cv. SG-40 GBR) was determined during the 1978 growing season. Actual evapotranspiration (ET, determined using weighing lysimeters), net radiation (R(, n)), and soil heat flux (S)
