farmers' fields with their active participation. ON-FARM RESEARCH PRACTICES Researcher-Farmer Relations When conducting research on farms, researchers are intruding upon the farmers' land and taking their valuable time. The research may be using other of the farmers' scarce resources. Because of this, it is well for the researchers to act always in the best interest of the farmers, treating them as equals in the research process and considering them as desirable, not just necessary, components in the technology generation, evaluation, and dissemination procedure. Farmers understand exper- imentation and are willing to participate if they feel they will possibly benefit from it, and if they understand what is happening. It is of utmost importance for researchers to explain fully why they are there, what they would like to do, what is going to be required of the farmers, and what the farmers can expect from the results. It is most important to explain why it will be of value and of interest to the farmers to be participants in the undertaking. Listening to and working with farmers From the very first contact made with farmers in the initial survey, or in looking for collaborators for on-farm trials or enterprise records, it is extremely important that the researchers begin by listening to and working with the farmers. Farmers resent being told by "government people" that they are doing things wrong, and that the "outsiders" know how the farmers should do it better. If the researchers convey this attitude to the farmers from the beginning, the relationship will get off to a slow start, if it gets started at all. Care must be exercised by the researchers to ascertain which of the household members are the decision makers and to talk with those who are responsible for specific crops. A wife may know little about her husband's cotton crop; he may know little about her cassava or peanut crop.
