Abstract

Infrared radiometry thermometer (IRT) is a tool that has proved its success on irrigation scheduling of many crops such as corn, sorghum, and cotton. Yet few studies have been done on dry edible beans. In this study, IRTs were installed at a dry edible bean field under various irrigation levels in western Nebraska during 2018 growing season. Crop water stress index (CWSI) was calculated during full canopy closure to quantify plant water stress. Preliminary results showed that average CWSI of full irrigation (100%) treatment (0.11) were lower compared to the rainfed (0%) treatment (0.46). This study will be presented in two parts and this paper presents part one: the experiment setup and calculation of CWSI for all irrigation levels, whereas part two of the study will discuss using different TSEB approaches to separate crop and soil component and calculate dry edible bean evapotranspiration.
