Determinação de estresse hídrico em cultura do feijoeiro com termômetro de infravermelho.

Abstract

With a hand-held infrarede thermometer were effected everyday measurements of canopy and air temperatures on bean submited to four application water regimes in order to calculate the stress days degree. With exception the Control all treatments didn’t present crop water stress. The highest yield was obtained by treatment which received less irrigation frequency and largest quantity of irrigation water.
