The current work was carried out with the aim of characterizing the productive units of small-scale agricultural systems of kiwicha (Amaranthus caudatus) in five communities of the Yungay, Huaylas, and Carhuaz provinces, Ancash region, Peru. The population sample of the production units under study was determined employing a proportional and stratified unrestricted random sampling. The information was obtained from primary (surveys and interviews) and secondary sources. The analyses were carried out by grouping qualitative and quantitative variables, and using multi-dimensional statistical techniques. Three types of producers that are similar inside each group were identified, and, at the same time, they have differences compared to other groups based on land tenure, areas sown with kiwicha and with a secondary crop, and monthly net income. The first group that included smallholding producers with 0.42 ha of arable land, possesses on average 0.14 ha cropped with kiwicha, and 0.17 ha of a secondary crop; the second group, comprised small producers with 0.53 ha of land available for their crops, have 0.30 ha of kiwicha, and 0.43 ha of a secondary crop, and the third group is composed of medium-sized producers that on average have 6.13 ha of land, of which 1.87 ha are cropped with kiwicha and 0.63 ha with a secondary crop. The monthly net income of medium producers with PEN 493.50 is higher than that of small and smallholding farmers in 176.52 % and 279.03 %, respectively.
