plots, developing insights of interest to their professional colleagues in universities and international research centers. This seems the most promising strategy for higher professional, social, and economic status. In contrast, conducting extensive on-farm trials, spending much time traveling in the field, and talking with extension agents and farmers is less attrac- tive to scientists and may present a serious role conflict.1 Coordination and feedback between research and extension is also related to the level of basic physical and institutional infrastructure. Agricultural scientists often feel their job is done when they have developed a superior seed variety, or ascertained that a particular chemical can deal with particular pest. Extension agents may be eager to popularize the seed or chemical. But thetaskof multiplying the seeds or manufacturing or importing the chemicals is not done by either the research or extension organization. It can easily be overlooked or mismanaged, with the result that researchers are annoyed that their suggestions are not being adopted, while extension agents are frustrated that they are not getting inputs from research. There is much room for experimentation and innovation with regard to policies that can maximize scientists' receptivity to feedback. A general value system and specific incentives which support and reward scientists who orient themselves towards farmers may be useful. The challenge is to do this without cutting a country off from international scientific exchanges--which tend to stimulate and reward scientific excellence and simultaneously break feedback loops with farmers.
