WebGro is a web-based soybean decision support system (DSS) built on the CROPGROSoybean model. The purpose of WebGro is to help soybean producers in the Midwestern United States understand how different stresses interact to limit soybean yield in their fields. Stresses include water, soybean cyst nematode, herbicide injury, Rhizoctonia root rot disease and hail damage. The user can set up a field scenario by selecting cultivar, planting date, plant population, soil type and the nearest weather station using a web form. Different stress levels can then be entered and the model can be run interactively by simulating the effects of one or more stresses at a time. The user can evaluate the yield loss relative to running the model with all stresses turned off (yield potential) to determine the effect of different combinations of stresses on yield.
