Uptake of improved sorghum varieties in Mali has been limited, despite the economic importance of the crop and long-term investments in sorghum improvement. One reason why is that attaining yield advantages that are substantial enough for farmers to discern in their own fields is difficult in a harsh, heterogeneous growing environment. Release of the first sorghum hybrids developed in Mali, which were developed primarily from the local Guinea race using a participatory approach, has the potential to change this situation. Here, we explore the adoption of improved sorghum seed with an ordered logit model, differentiating between improved varieties and hybrids. We then apply a multivalued treatment effects model to measure impacts on farm families. We utilize primary data collected from 628 farm family enterprises in the Sudanian Savanna region of Mali.
