GOSSYM/COMAX, the cotton crop simulation model and Cotton MAnagement eXpert system, is an excellent example of a successful technology transfer of collaborative research work from USDA-ARS-CSRU, Clemson University and Mississippi State University. It was hailed as an innovative approach to cotton crop production when it was first introduced in mid-1980s. Its success lies in its state-of-the-art effective utilization of the latest research on the growth and development of cotton, weather stations and personal computers. Extension agents were encouraged to demonstrate and use the system to help their constituents in the management of their cotton crop. Despite GOSSYM/COMAX limitations, it has gained popularity not only in the US cotton belt but also in countries like France and China. The system is continuously being improved--with the addition of an insect model (rbWHIMS), AGBOOK and now as part of a precision agriculture project that will provide links to GPS and GIS. The number of users--researchers, consultants and producers-- reached its peak in the early 1990s. However, in spite of all the efforts put into the system to make it more user-friendly and accommodating to users' suggested improvements, it is slowly losing its ground as a management tool. Primary sources of dicontent and apathy in the use of GOSSYM/COMAX were related to the amount of data and time required to run the system, the cost of hardware and software, and the lack of technical support.
