the purpose of this paper is to report the use of cotton canopy temperature measurement to detect crop water stress which results from both soil water deficits (matric potential stress) and soil water salinity (osmotic potential stress). canopy and air temperature difference, in conjunction with ambient vapor pressure measurements, formulated into the crop water stress index appears to be useful in quantifying crop water stress from both soil water deficits and soil salinity. therefore the crop water stress index appears useful for indicating the need for irrigating cotton. 25 refs
