the purpose of this article is to explain the origin and development of vegetable production in Northwest Mexico. It is hypothesized that horticultural nodes, particularly those in Sinaloa, are the result of dialectic synergy between external (foreign investment, business migration, U.S. industrialization, technology transfer, etc.) and internal shocks (public policy, comparative advantage, learning, etc.), where the former play a determining role in the evolution of growth trajectories in the zones of production. Through an analysis of the history of Sinaloa´s horticulture in three stages, the original causes and the failed upgrading process of this sector after its boom during the 1920’s are shown, as is the downgrading process which began in the 1980’s.
