• W2155497406 abstract "This paper evaluates the level of adoption of improved groundnut varieties and the role ofinformation, seed supply and credit constraints for variety adoption in rural Uganda. We uselarge-scale primary survey data collected in seven groundnut growing districts to understandthe adoption behavior of farm households and the key determinants of variety uptake. The studyfinds that the level of adoption of improved varieties in Uganda is very high; about 59% of thehouseholds grow improved varieties. About 62% of the groundnut area is planted to improvedvarieties, indicating a high intensity of adoption. On average, the income per ha from improvedvarieties is about 80% higher than local cultivars. Owing to the interdependence of varietychoice decisions, we use a multivariate probit specification to identify variety-specific drivers ofadoption. About 10% of farmers lack information on new varieties, while 18% and 6% cannotadopt mainly due to seed supply and capital constraints, respectively. This indicates that a tobittypespecification, which considers all non-adopters as disinterested in the technology wouldlead to inconsistent parameter estimates and misguided conclusions. We therefore estimate amodified multi-hurdle specification, which takes into account the information, seed supply andcapital constraints in determining the desired demand and intensity of adoption of new groundnutvarieties. These findings provide new insights as to why adoption of new agricultural technologiesin Africa has lagged behind – not so much due to lack of economic incentives, but due to thepersistent failure to provide vital information along with seeds and required credit to translate thedesired positive demand into effective and actual adoption of new varieties. These are importantlessons that need to be considered as Africa searches for alternative pathways to launch aneffective and sustainable green revolution that will transform smallholder agriculture.Shiferaw B, Muricho G, Okello J, Kebede T A and Okecho G." @default.
