On-farm trials: a survey of methods.

The paper reports the results of a survey of 41 practitioners who where asked to report on the methods they were using on their projects, and the reasons for their success or failure. Most importantly this conventional approach to farming systems research failed to incorporate the experience and knowledge of farmers into its survey design. It is concluded that simple research questions can often provide the needed information in order that technologies useful to resource poor farmers are developed. [Abstract based on mimeo version]
