MONTES-ROJAS, CONSUELO; BURBANO-CATUCHE, GUIDO ARY; MUNOZ-CERTUCHE, EDWIN FERNANDO y CALDERON-YONDA, YIMY. DESCRIPTION OF PHENOLOGICAL CYCLE OF FOUR ECOTYPES OF(Chenopodium quinoa Willd.) AT PURACE - CAUCA, COLOMBIA. Rev.Bio.Agro [online]. 2018, vol.16, n.2, pp.26-37. ISSN 1692-3561. https://doi.org/10.18684/bsaa.v16n2.1163.
At Cauca, municipality of Puracé, sidewalk The aquarium, located at 3023 meters above sea level, within the framework of the Quinoa production chain project, the phenological cycle of 4 quinoa ecotypes and their yield were evaluated in order to select and determine the duration of the stages of the productive cycle that determine their agronomic management at heights greater than 3000 meters above sea level. The purpose is to look for a potato crop rotation option that will contribute to regional food security. This study was carried out during 2016 under field conditions, in the indigenous reservation of Paletará. We used a randomized complete block design with 3 replicates where treatments were ecotypes, phenological stages were recorded, saponin content and performance were evaluated. It was determined that quinoa presents two well marked phenological stages, vegetative stage with 6 phases and reproductive stage with 7 phases; the duration of the productive cycle of the 4 ecotypes was between 154 and 213, allowing to classify them as semiearly and semidelayed, the content of saponins was between 0.005 and 0.012%. It was concluded that of the 4 ecotypes evaluated, aurora is recommended for precocity, sweet taste and better yield.
