Interpretive Summary:

Technical Abstract: For researchers, canopy temperature measurements have proven useful in characterizing crop water stress and developing protocols for irrigation management. Today, there is heightened interest in using remote canopy temperature measurements for real-time irrigation scheduling. However, without the use of wireless infrared thermometers, it is difficult to monitor canopy temperature on a frequent basis and manage irrigation scheduling at the field scale level. ARS scientists at Bushland, Texas have integrated a plant-feedback system with a center pivot irrigation system using a wireless sensor network of infrared thermometers and weather data to respond to site-specific crop water needs. This presentation will discuss methods for full-and deficit-irrigation of crops of importance in the Southern High Plains region, and measured crop response to this irrigation scheduling system (yield and water use efficiencies) from field studies that compared the system to scheduling based on weekly neutron probe water content readings.
