Multivariate characterization of tarwi (Lupinus mutabilis Sweet) producing farms of the Mantaro Valley, Peru. Scientia Agropecuaria [online]. 2018, vol.9, n.2, pp.269-279.

The objective of the work was to characterize the tarwi producing units in the Mantaro Valley, Junín-Peru. The source of information was the producers of tarwi (N = 490) that made up the study sample (n = 114) of four inter-Andean localities: Acolla, Cruz Pampa, Quicha Grande and Hualahoyo. The data collection was carried out through structured surveys that included topics in technical and socio-economic aspects, and were analyzed using multivariate analysis techniques. The results obtained from the typification of rural producers of the Andean ecosystem, allowed to identify three management forms well differentiated from each other, product of factor analysis by factor rotation, varimax with Kaiser normalization and Cluster Analysis Ward method. The synthetic variables constituted "resources of the property" with explanatory power of 26.71% (6 variables, 56.14% of the sample); "Socio-environmental reality" with 7.59% (2 variables, 29.83% of the sample) and "social dimension" with 5.00% (1 variable, 14.04%). "Resources of the property" was the majority of small and medium producers, with vast Andean rural experience, traditional technology and great uniformity within their type, using only their available resources to the logic of their production, certainly with different strengths and weaknesses.

Keywords : Characterization; typification; rural producers; tarwi; multivariate analysis.
