Interpretive Summary:

Technical Abstract: An object oriented model for stimulating crop and weed competition under field conditions has been developed for educational and research purposes. The model can be used to study seasonal dynamics of crop and weed canopies which are important in controlling crop photosynthesis, evapotranspiration, rainfall interception, soil erosion and crop-weed competition. The software was developed based on years of field experimental data take in Urbana, IL, USA. The software runs with a user-friendly interface in Windows 95 and Windows NT. The model simulates field physical and hydrological processes, and predicts crop and week phenological events according to temperature, photoperiod, water moisture and other field conditions. The user can input the parameters required by model for simulating user specified crops or weeds. Examples are given for soybean and velvet leaf in the model. Functions for data comparisons, X-Y plots, regressions and curve fits are available for data analysis.
