The premise that on-farm experimental research is necessary has been widely accepted by those agricultural researchers in Africa who have been exposed to on-farm research philosophies.  By teaching and reviewing on-farm research programs, I have become aware of the unique practical and conceptual problems involved in on-farm research.  This manual, therefore, aims to address these problems through demonstrating techniques of on-farm experimentation.
