Optimal irrigation based on ET estimates for new stress tolerant corn hybrids in Texas High Plains Increasing irrigation beyond 75% of evapotranspiration or increasing plant density in excess of 30,000 per acre did not increase corn silage yields.
Yield and water use of stay green and senescent varieties of sorghum grown in four soils under limited irrigation Under extreme water and heat stress that occurred in 2011, a stay green variety of sorghum produced significantly larger grain yields due to a larger number of seeds per square meter.
BIOTIC irrigation method for controlled deficit irrigation on cotton. In a production setting, continuous canopy temperature provided a potentially useful validation of the accuracy of ET estimates that might help to manage deficit irrigation.
Can Deficit Irrigation Scheduling Be Improved for as Little as $5.00? Stress Degree Hour (SDH) irrigation scheduling more closely approximates scheduling by Crop Water Stress Index (CWSI) than does the Stress Time (ST) irrigation scheduling approach.
Assessment and improvement of deficit irrigation scheduling techniques using canopy level gas exchange measurement A team of researchers evaluated a system designed to measure crop performance at the whole plant level called CETA (Canopy Evapo-Transpiration and Assimilation) chambers and found that they performed well under field conditions.
