Abstract Agriculture has a long tradition of randomized experiments in the research station and of comparative demonstration plots under scientist control. The BDK Nobelists have pioneered randomized field experiments under agency control to fight global poverty, thus making behavior, contextual circumstances, and institutional constraints key determinants of outcomes. In agriculture, experimentation has massively responded in jumping the fence from lab to field, with already major advances as to how to better use agriculture for development. We document how this has happened and how the methodology of field experiments has to be adapted to perform in the challenging context of developing country agriculture.
