A field experiment was conducted with a cotton crop subjected to two different irrigation treatments. The objective was to evaluate diurnal and seasonal variation of Crop Water Stress Index - CWSI based on the energy balance and its feasibility in irrigation water management. Measurements of canopy and air temperature, net radiation, wind speed, and water vapor pressure were made daily at 9h30 and 13h30, and many diurnal cycles at hourly interval between 6 h to 17 h. Porometric measurements were also used to evaluate the crop resistance. It was concluded that irrigation should be made when the CWSI reaches 0.3.
