Four years of farmer experimentation on soil fertility in Tigray, northern Ethiopia: trends in research strategies

ABSTRACTPurpose: This paper analyses research strategies followed by farmer groups in Tigray, that were involved in participatory experimentation. Understanding choices made by farmers in such experimentation processes is important to understand reasons why farmers in Tigray often hesitated to adopt recommended practices.Design/Methodology/Approach: A participatory experimentation approach was followed to arrive at recommendations matching with local preferences and context. In total, 16 groups of 5 farmers were monitored during 4 years.We monitored research strategy of the farmer groups by considering the following: (1) the type of treatments, (2) the inclusion of responsive treatments, (3) the actual responses achieved and (4) the treatments perceived optimal.Findings: We found that the farmer groups followed a very rational, context-rooted strategy that, e.g. in its focus on straw production and the use of combinations of organic and mineral fertilizers, differed from that of the researchers.Practical ...
