Abstract

A 6-yr interdisciplinary field project using large plots was initiated in 1985 to assist Pacific Northwest growers in developing an integrated pest management system to control weeds, reduce erosion and grow crops profitably. Run by a network of 10 to 14 scientists from eight disciplines supported by five agencies, the project showed that wellmanaged conservation tillage systems had a higher average profit and lower economic risk than traditional conventionally tilled systems. Information was disseminated successfully to user groups by field days, plot tours and an educational video. Organizational strategies included an interdisciplinary design with three levels of objectives. Cooperating scientists were invited to participate in writing the proposal and followed strict field protocols and attended mandatory organizational meetings. This long-term study used large machinery, went beyond the transitional stage and allowed treatments to mature. Limitations included the restricted number of experimental variables, the location of the plots, the large labor force required, and publication decisions.
