A thermal infrared technique for monitoring cotton water stress and scheduling irrigations
1982
Pinter, P.J. Jr | Reginato, R.J.
Stepwise, multiple linear regression analysis established that a crop water stress index (CWSI) derived from mid-day radiant leaf temperatures, air temperatures, and vapor pressure deficits was the most important independent variable in predicting the xylem pressure potential of cotton leaves. When the CWSI was combined with the age of the crop and the evaporative demand of the atmosphere, the water potential of cotton could be predicted throughout the entire growing season. This permits day by day monitoring of cotton plant water status which could facilitate the irrigation decision making progress without resorting to tedious physiological plant measurements.
