Adoption and impact of high-yielding wheat varieties in northern Tunisia.

Saade, M.E 1996

CIMMYT Economics Working Paper 96-03. Mexico, D.E: CIMMYT.

This study assesses the extent to which durum and bread wheat high yielding varieties (HYVs) have been adopted by farmers in northern Tunisia, a region which accounts for more than 80% of the nation's durum wheat production and close to 90% of its bread wheat production. Estimates are presented of the areas grown to various HYVs by agroclimatic zone and farm size. The adoption history of each wheat HYV is outlined, including its date of release, its peak adoption, an (if applicable) its disadoption. The impact of HYVs is discussed; particular attention is devoted to genetic yield gains, impact on farmers' income, and impact at the national level.
