Draft

This study analyses the factors influencing the adoption of conservation tillage in two districts in Ethiopia and assesses its impacts on land and labor productivity. The adoption of the different components of conservation tillage was analyzed using a multivariate probit model and the impacts were estimated using generalized methods of moments and the control function approach to deal with the common problems of endogeneity and heterogeneity. The results show that the initial decision to adopt the different components of conservation tillage package is influenced by location, family size, access to extension, and formal education. Among the components, herbicide application was found to be significantly and strongly influencing land productivity. Other factors that influence land productivity are location, sex of the head of the household, livestock wealth, and human labor endowment. None of the components were found to be influencing labor productivity. Given the scarcity of land in Ethiopia, the contribution of herbicide application towards improving land productivity within conservation tillage efforts should be investigated further at the policy level in view of achieving more efficient and sustainable land use. Also, efforts should be sustained to expand extension services so to generate greater awareness about the multiple benefits of conservation tillage.
