A field study was conducted during the 1977 growing season to determine the effect of soil-water content on the air temperature within and above the soybean canopy and consequently on the leaf temperature and stomatal resistance of soybeans (Glycine max L. ’Calland’). Leaf temperature at two heights and air temperature at five heights within and above the canopy were measured with copper-constantan thermocouples while stomatal resistances were measured with an automatic porometer. At soil-water depletions 65% air temperature decreased with height. In the first case the canopy temperature was cooler than the air above the canopy when air temperature exceeded 32 °C and the lower canopy leaves were cooler than the upper canopy leaves when they were completely shaded by the upper leaves. At soil-water depletions greater than 65% the canopy was warmer than the air and the lower canopy leaves were warmer than the upper canopy leaves. Stomatal resistance, on the other hand, decreased with height within the canopy irrespective of soil-water content.
