Descripción y propuestas técnicas para el cultivo de Quinua (Chenopodium quinua Willd.) en la Comarca Andina del Paralelo 42°: estudio de caso en Mallín Ahogado, Río Negro.

Abstract

Quinoa (Chenopodium quinua Willd.) is an ancient crop that has gained global importance for decades due to its nutritional quality and agronomic versatility. This species has been cultivated in northern Patagonia since the 19th century. Currently, several quinoa cultivation experiments are being carried out in the Andean Region of the 42nd Parallel (CAP 42°) within the context of family farming, for personal consumption and sale of surpluses to local markets. At the same time, there are no scientific and/or technical studies documenting and evaluating these productions. This final project for the Technical Program in Organic Plant Production at the National University of Río Negro (TPVO - UNRN) proposes the general objective of analyzing and evaluating, in terms of management and yield, the local cultivation of quinoa in an associative family farming project in Mallín Ahogado (El Bolsón, Río Negro), with the aim of proposing actions to improve the cultivation system. This case study is the first to document local quinoa management practices in CAP 42°. The results conclude that the high phenotypic variability recorded in the crop can be considered the greatest deficiency for this productive cycle and that the management of the lot prior to planting and during crop development, along with an adjustment in the selection of plants that will be used as seed for sowing, are key points to mitigate this effect.
