Throughout the growing season, the cotton plant provides an accumulative record of its growth and development. The Arkansas system of plant monitoring is a means to adjust crop management based upon plant response to pests and environment. At present, the system integrates the plant growth pattern (determined by TOPMAP and NAWF) and the historical weather into an expert system (COTMAN) to assist with end-of-season management decisions. As the system continues to be developed, additional variables from TOPMAP, COTMAP and other monitoring tools will be added to form a comprehensive and integrated crop management system.
