The nature of the relationship Farmers should be aware from the beginning exactly what to expect from the relationship. Above all, they must be informed that the work is research, from which both researcher and farmer will learn, and not a demonstration designed to show how much better the researchers can do what the farmers are already doing. (In most cases, the farmers know how to do it better, but they cannot afford to.) Farmers must be aware of who will be expected to provide what, who will take what risks, who will get what product. It is critical that farmers understand the timing of the various activities and whether it is to be at their initiative or at the initiative of the researchers. For example, in a yellow maize area, if some white varieties are to be used, the farmers should know if they can expect some yellow maize in return for the white maize they will not want, or if they should just expect to lose that which was produced. They should also agree to include white maize and understand why it should be included. They must know who should provide the fertilizer, if it is to be used, and when it must be available; who is going to harvest, when and how. Farmers understand risk and are willing to (or are forced to) accept it as a normal part of their production environment. If an experiment is lost because of normal environmental conditions, farmers will understand it and will not be concerned about compensation (although they would probably accept it if offered). In order to avoid paternalism in the research process, it is better not to consider compensation for these cases. If, on the other hand, certain treatments are lost because they were poorly thought-out or obviously not adapted to the production environment of the farmers, the farmers can be expected to think compensation is warranted unless they were well advised beforehand of this eventuality. In this case, payment in kind, of the quantity and quality that otherwise would have been produced, is probably indicated. It is better, of course to avoid the situation by having well-thought-out, simple interventions and adequate farmer involvement in the design of the trial. Farmers must understand the importance of the trial to the researchers. The risk of not completing on-farm
