The 1988 evaluation of GOSSYN-COMAX under dryland conditions with a stripper variety provided many useful experiences. The dependence on external sources for generation of soils files and variety calibration files continues to be a hurdle for potential Texas GOSSYM-COMAX users. Cooperators are required to spend from $7,000 to $10,000 for hardware to evaluate the system. However the data base for support, with regard the soils and stripper varieties, does not exist. The model did an acceptable job of predicting plant growth and development. The predicted yield response to supplemental nitrogen did not occur. Future efforts need to be focused on development of more comprehensive variety files for stripper varieties.
