註釋Adopting improved varieties is key for improving agricultural productivity and farmers' quality of life in developing countries. The objective of the study was to examine determinants of Nigerian farmers' decisions to adopt improved cassava variety (ICV) traits, classifying the traits into three different groups : resilience, marketability, and cooking quality. The data used in this study come from a survey of 1,087 households conducted in four regions of Nigeria in 2015, focusing on adoption of ICVs. Using Tobit and Seemingly Unrelated Regression (SUR) models, the results showed that the determinants of adoption vary across traits. For instance, adoption of ICVs with superior cooking quality traits is affected by extension agency contact, and credit availability. On the other hand, determinants of trait adoption with resilience characteristics are household size and household's cooperative membership. Furthermore, living in the North region has a positive effect on adoption of resilience trait, while it negatively affects adoption of marketability and cooking quality traits. Besides, the proportion of cassava used for home consumption purposes shows a negative correlation with adoption of ICVs and traits.
