Abstract: This study examines the agroecology and bioculturality of Oxalis tuberosa Molina, in the Montúfar canton, Carchi province, Ecuador, an area where this Andean tuber is cultivated at altitudes above 3000 m and in soils with a pH between 5.3 and 7.8. The research was conducted in the Producampo Producers Association, composed of 33 active members, of which 87.5% are women, with an average age of 51.25 years. Oxalis tuberosa constitutes an important crop in their integrated agroecological production systems (IAPSs): the production of bio-inputs in SIPA systems is predominantly self-sufficient, with 75% of producers using exclusively their own organic fertilizers, mainly compost and vermicompost, and showing low dependence on external inputs, whether organic (12.5%) or chemical (25%); the latter are applied in small doses of about 5 kg every six months in secondary crops. The research adopted a mixed methodological approach, integrating semi-structured interviews for qualitative analysis using Atlas.ti and descriptive statistical analysis with specialized software. Of the total Oxalis tuberosa production, 80% is intended for personal consumption and 20% is sold at local markets. Cultivated ecotypes include “blanca” (70%) and “chaucha” (30%), both of which are resistant to pests but susceptible to frost. Families dedicate between 32 and 80 h per week to production, with an average of 56 h. The findings highlight the potential of Oxalis tuberosa to improve the food resilience of Andean communities and suggest that revaluing this crop and its traditional practices can improve agricultural sustainability in the region.
