In Colombia, Nariño is the main pea-producing department that supplies approximately 54 % of the national demand. The main producing area of this legume is concentrated in the Obando or southern subregion of the department, where pea (Pisum sativum L.) shows adequate environmental conditions and develops under family farming. In this study, we sought to identify typologies of farms dedicated to this crop, for this, a heterogeneous sample of 1.067 farms in five municipalities of the southern subregion (Córdoba, Cuaspud, Iles, Ipiales and Potosí) was taken. Following the methodological framework proposed by the International Network of Research Methodologies in Production Systems (rimisp, for its acronym in Spanish) to georeference each farm and apply a structured survey with 39 variables. The information obtained was subjected to Multiple Correspondence and Hierarchical Grouping Analyses. As a result, 12 variables with discriminant power were identified, which formed three clusters: C1 grouped 6 % of the sample (68 farms), C2 assembled 26 % (271 farms) and C3 grouped 68 % (728 farms). Each group showed particular characteristics regarding the property, agro-productive strategies, and social, environmental, and economic aspects that described the heterogeneity of the farms associated with pea cultivation. It is expected that the results will contribute to the characterization and selection of representative farms for future sustainability estimation works.
