To investigate the impact of a policy intervention on technology adoption by small scale farmers, we conducted sequential field experiments on maize production in Uganda in 2009, in which we provided a free maize start-up package to sample farmers in randomly selected villages. Subsequently, we conducted a sales experiment in each of the treatment and control villages involving all the sample households and their randomly selected neighbors in the treatment villages. The findings of this study suggest that the distribution of modern agricultural inputs has a significantly positive effect on their adoption by farmers who have little experience in their use. We also find a large impact of the credit intervention and significant spillover effects. In short, a small-scale intervention could have a large impact on farmers’ demand for modern inputs and maize yield.
