Abstract
Purpose: Adequate information is necessary for investments. We use data from a randomized controlled experiment in northern Ghana to advance knowledge on which communication options are most effective for reaching farmers with a new technology (Bradyrhizobium inoculation) to boost adoption. Farmers received information through either video documentaries or radio listening clubs. Joint test of all treatment effects provide strong evidence that the video was effective for inducing technology uptake and increased yields; the radio listening club effects were mostly imprecise, partly due to insufficient statistical power. We conclude that barriers to learning about correct technology usage or benefits constrain adoption.
