Temperatura de dossel versus tensão de água no solo.

Abstract

A field experiment was conducted in Cerrado condition of Distrito Federal of Brazil, to verify the effect of four levels of soil-water tension (50, 100, 500 and 900 kPa) on canopy temperature of barley. Water was applied to the crop when soil-water tension at 0.15 m deph reached values set for the trataments. It was verified that the levels of soil-water tension affected the canopy temperature of the crop.
