The result show that the evolution of the old farms began with a partial occupation of land by the date palm followed by an introduction and extension Plasticulture then became a holding palm where other crops are marginalized. The truck farming system production in the region is profitable and has been widespread, but remains cyclical and tends to be replaced by the mixed systems (phoeniculture –gardening) to become a purpose – palm.frArticle
