Handbook for Field Trials in Technical Cooperation / Klaus Rohrmosen, [manual] copublished in English by GTZ/CTA.
All programmes set up to develop agricultural production have a common goal: the introduction of improved techniques which are adapted to the local climate, economically viable and acceptable to small farmers. Before laboratory results can be applied in the field, they must be tested under real growing conditions so their true value becomes clear and the optimal conditions for their widespread application can be determined. Such field trials must be planned, carried out and analysed in a methodical way. The West German Agency for Technical Cooperation (GTZ) has published a handbook on field trials by Klaus Rohrmosen, which CTA helped to make available in English. There are very few practical books on this subject, and the GTZ manual fills this gap. It covers all the basic procedures for conducting field trials. It can be used as a teachyourself handbook, or as a reference book, and is a useful guide to the different types of equipment needed for field trials. The section on the evaluation of results is presented very simply and limits itself to the essentials. The book is aimed at all agricultural technicians, including those who are not familiar with the subject.
