Abstract

Field studies were conducted on five crops in Arizona to determine relationships between crop yield and the crop water stress index (CWSI). Small plots and/or commercial fields of long and short staple cotton, wheat, pecans, and watermelon were irrigated at preselected CWSI values representing low to high crop water stress levels. When using optimum CWSI irrigation scheduling values, a lower CWSI irrigation threshold should be used based on the time expected to elapse between the last CWSI reading and the actual irrigation event.
