Område Jordbruk - odlingssystem, teknik och produktkvalitet www.slu.se David Hansson 2009-12-08 Project: Effective weed management in row- grown organic vegetables Participatory research The experiments were designed and analysed etc. after a discussion with: farmers, advisers and researchers The experiments were performed on 3 different farms
4
Participatory research Exchange of experience between farmers, advisers and researchers. Participatory research gives more solutions and faster changes. Present issues are in focus which gives a greater engagement. Participatory research involves a holistic approach to solve problems. The hole group is responsible to ask questions, analyse and participate. David Hansson & Sven-Erik Svensson 2011-03-28 Swedish University of Agricultural Sciences, Alnarp
