Abstract: The study sought to examine adoption of nutritious drought tolerant (DT) maize using social science research methods and participatory demonstration trials. The social science study used mixed method approach which combined both qualitative and quantitative methods. A split-plot demonstration trial of three improved maize varieties and a local variety, and two levels of Nitrogen fertilizer were established. The two fertilizer levels were low N [LN] (30 kg N ha-1) and high N [HN] (90 kg N ha-1). The results of the social science study showed 85% of men consider early maturity, grain quality and storability in adopting DT maize. Results also revealed that beside earliness and higher yield, taste and easy to harvest influenced women farmer’s choice for DT maize varieties. Climatic endurance, increased yield and grain quality showed a positive and statistically significant relationship with adoption of DT maize. On average, HN fertilization increased DT maize grain yields by 41% compared to the LN fertilization. The improved DT maize varieties had yield advantages ranging from 25 to 43% over the local variety. From this, DT maize appears to have a potential for its use with N-fertilizer in the fight against food insecurity with improved adoption and utilization in Ghana.
