a vast area of the municipality of envigado, antioquia-colombia, is considered a rural zone. in this zone, the districts of perico and pantanillo stand out for their traditional production of blackberry crop. in the past few years, blackberry producers have encountered new major competitors due to elements that have strengthened the competition. factors such as: the technification of crops, urban infrastructure improvements, and the establishment of competing productive chains in adjacent municipalities. nevertheless, despite still being developed with very traditional techniques, the blackberry crop is still profitable for local producers. therefore, the objective of this work is to calculate the actual level of blackberry productivity and to identify some of the principal determinants of said productivity. for this purpose, strategic information from a representative number of blackberry producing farms was collected. the research shows that some factors have become determinant differentiators of blackberry production. among these factors are: the use of inputs, soil qualities and level of associativity.
