Summary: This paper outlines objectives for conducting on-farm trials and presents a typology for classifying on-farm trials, focusing on how different types of trials may be used to meet different objectives. It presents the rationale for conducting on-farm trials, the main elements of participatory technology development, and a classification for on-farm experiments based on the degree of control over the experiment by scientists and farmers. The classification recognizes three types of trials, depending on the objectives of the trial, who designs it, and who manages it. Type 1 trials are researcher designed and managed and their objective is to assess biophysical responses. Type 2 trials are researcher designed and farmer managed, e.g., farmers agree to implement a common design. It is useful to get farmer feedback on specific prototypes or for conducting economic analyses. Type 3 trials are farmer designed and managed where farmers can experiment on their own. The objective of this type of trial is to assess farmer innovation and acceptability.
