Abstract
This study examines the impact of investments by GRZ and international agencies that led to the development and adoption of ten improved maize varieties. Maize investment impact was assessed from three levels. First, results from an adoption survey of farmers in all major maize growing areas were used to calculate a rate of return (ROR). Because farmer adoption was influenced not only by research but also by non-research complementary investments in seed, extension, and marketing, these costs were included in the ROR calculation. Second, numerical simulation was used to estimate the effect on the ROR and other indicators assuming that key marketing and price policies had not been in place. Third, the study examined the historical interplay of institutional and organizational factors that led to the initial choice of maize policies and affected their fiscal sustainability.
