Additional Information



This paper evaluates the level of adoption of improved groundnut varieties and the role of information, seed supply and credit constraints for variety adoption in rural Uganda. We use large-scale primary survey data collected in seven groundnut growing districts to understand the adoption behavior of farm households and the key determinants of variety uptake. The study finds that the level of adoption of improved varieties in Uganda is very high; about 59% of the households grow improved varieties. About 62% of the groundnut area is planted to improved varieties, indicating a high intensity of adoption. On average, the income per ha from improved varieties is about 80% higher than local cultivars. Owing to the interdependence of variety choice decisions, we use a multivariate probit specification to identify variety-specific drivers of adoption. About 10% of farmers lack information on new varieties, while 18% and 6% cannot adopt mainly due to seed supply and capital constraints, respectively. This indicates that a tobittype specification, which considers all non-adopters as disinterested in the technology would lead to inconsistent parameter estimates and misguided conclusions. We therefore estimate a modified multi-hurdle specification, which takes into account the information, seed supply and capital constraints in determining the desired demand and intensity of adoption of new groundnut varieties. These findings provide new insights as to why adoption of new agricultural technologies in Africa has lagged behind – not so much due to lack of economic incentives, but due to the persistent failure to provide vital information along with seeds and required credit to translate the desired positive demand into effective and actual adoption of new varieties. These are important lessons that need to be considered as Africa searches for alternative pathways to launch an effective and sustainable green revolution that will transform smallholder agriculture.
