Quinoa (Chenopodium quinoa Willd.) originates from the Andeanregion of South America and is known as “the golden food” due to its nutritivetraits such as protein, zinc, fiber, and folate, as well as antioxidants. The cropis of interest in several countries under climate change because it adapts to variousabiotic stresses such as salinity, water deficits and low temperatures. Vietnam isone of the five countries that are most severely affected by global climate change.Therefore, the successful introduction of quinoa would make a great contributionto agriculture for better livelihoods and economies for the farmers.This study aims to identify quinoa genotypes that can effectively adapt todifferent ecological regions of Vietnam. To achieve this, it employed several stabilityparameters as well as additive main effects and multiplicative interaction(AMMI) analyses to determine the best genotype for each environment/locationamong 40 genotypes across three environments. The results revealed significantvariations in growth and yield among tested genotypes. Analysis of the varianceof AMMI indicated that genotype (G), environment (E), and G × E interactionhad a significant influence on quinoa growth and seed yield. Based on the AMMImodel for seed yield, “Atlas”, “Cahuil” and “2-Want” were found the most stableacross tested environments.To develop appropriate cultivation methods, the effect of the sowing plantingdensities (80,000, 100,000, 133,000, and 200,000 plants ha−1), and nitrogen dose(80, 100, 120, and 150 kg ha−1) were also investigated for the “Atlas” varietyin Son La, Dak Lak, and Soc Trang provinces. The results suggested that in SonLa, the sowing date for the spring cropping season starts in early February, whilethe winter cropping season, begins in early September and lasts until the 20thof September. The suggested plant density for both seasons is 100,000 plantsper hectare. In Dak Lak, the optimum sowing date for quinoa starts in February(1st- 20th February), with a density of 100,000 plants per hectare. For the wintercropping season, the sowing date is from the 1st to the 20th of October, with adensity of 80,000 plants per hectare. In Soc Trang, the suitable sowing date forquinoa is between the 15th and 20th of January, with a density of 133,000 plantsper hectare. For the winter cropping season, the sowing period is from the 1st tothe 5th of October, with the same density of 133,000 plants per hectare. Regardingthe appropriate amount of nitrogen fertilizer for growth and yield of quinoa in thethree ecological zones, it is recommended to use 120 kg of nitrogen per hectare.Our results constitute the first crop management recommendation for quinoa inVietnam.
