The average maize yield in Ghana is estimated to be 1.7 metric tons/hectare (MOFA?2009?2011), whereas achievable yields based on on-farm trials are between 4 and 6 tons/hectare. Low adoption of inputs and improved technologies is often cited as the major reason for such a gap. To determine adoption levels and better understand the constraints and incentives for technology adoption, a nationally representative survey of 630 maize farmers in 30 districts in nine regions in Ghana was implemented between November 2012 and February 2013. The study aims to provide up-to-date and rarely collected nationwide data and analysis on the patterns of adoption of improved technologies for maize in?Ghana.
