\textbf{Abstract}
\begin{abstract}
\normalsize{
Developmental research policies that are implemented through Agricultural Innovation System concepts usually aim to transform the livelihood of rural household in developing countries. As a result, there has been a shift in the research paradigm in many African countries like Nigeria; from top down research systems to nonlinear dynamic systems that aim to enhance end users capacity to obtain and utilise knowledge and research outputs. However, adoption of innovative technologies through soft transfer, co"=creation or community"=based approaches may define the path out of food insecurity and poverty in developing countries. We used a non"=parametric propensity score matching (PSM) technique as a means of establishing a valid counterfactual and single differencing to measure impact and Linear Regression with Endogenous Treatment Effects on data from 120 farmers in Oyo state, Nigeria to investigate, the impact of cassava Pro-Vitamin A Technology adoption on farmers' income and productivity. We also disentangled drivers of adoption and bias in self"=selection among adopters and non"=adopters. We found that access to extension services and costs of inputs were the main drivers of adoption. Poverty level was also recorded as determinant of adoption. The empirical evidence from the Linear Regression with Endogenous Treatment Effects revealed that the adoption of cassava PVA technology positively related with both yield and income. We also demonstrate that adoption of PVA technology has a positive and significant effect on yield and income. The policy message from this is quite clear: more investment and complementary incentives targeting more yield and income among cassava farming household are needed for impactful scaling of innovative technologies.
