Technical Abstract: Concerns over declining water levels in the southern Ogallala Aquifer region have spurred research efforts to extend limited groundwater resources, including the cultivation of less water-intensive crops such as cotton. Relatively low water requirements coupled with favorable market prices have led to increased upland cotton acreage in the northern Texas Panhandle. However, weather-related challenges such as excessive precipitation in early spring can delay or prevent planting prior to crop insurance deadlines. Severe thunderstorms may also damage or destroy established crops, preventing replanting due to late season heat unit limitations. Although short-season soybeans can be an option for producers, crop water use (evapotranspiration, ET) data for late-planted soybeans in a semiarid environment are limited. We present and discuss seasonal ET data (sprinkler and SDI) for a short-season soybean hybrid grown on the large weighing lysimeter fields at the USDA-ARS Conservation and Production Research Laboratory at Bushland, Texas.
