Abstract: Abstract This paper uses data collected from 452 sampled households to estimate the impact of improved sorghum varieties (ISVs) on poverty reduction in Tharaka Nithi County, Kenya. Consumption expenditure per adult equivalent is used as the poverty indicator. Different matching methods complemented by endogenous switching regression model were used to ensure robustness of the estimated results. The impact results generated by the three models are consistent and affirm poverty reducing effects of adopting ISVs. Therefore, this study recommends formulation and implementation of adoption-stimulating policies that target to raise resource endowment of households, improve access of extension service and rural infrastructure.
