    Abstract: This paper assesses the return to DT maize using four years of data from on-farm yield trials and high-resolution precipitation data (10-day measurements at a 0.05° resolution) in southern Africa to assess claims of the DT maize advantage. On farms (rather than controlled trials) DT maize yield slightly exceeds that of other varieties: 7% higher yields on average, and 15% higher yields under moderate drought stress with additional heterogeneity in returns across high and low performing farms. For low-performing farms, a net loss of $10/ha of DT maize increases to a net gain of $30/ha in a drought year.
