Abstract: | This study analyses the pattern of spatial diffusion of kolanut (Cola nitida) production in south-western Nigeria between 1900 and 1970 and examines the factors which were responsible for the observed spread of kolanut production within the region. Sections: Introduction - The pattern of spatial spread - The rate of diffusion - The core-periphery character of the Kola Belt - Factors promoting the spatial spread of kola - Constraints on the spatial spread of kola production - Conclusion.
