The present work of investigation titled: Yield of the cultivation of quinoa (Chenopodium quinoa Willd.) (Amaranthaceae), developed in four densities of sowing under sandy soil conditions", and with the cultivar Salcedo INIA had as objective to contribute to the understanding on the effects of the population density, being of 300, 400, 500 and 600 thousand plants ha -¹ evaluating the yield of kg ha -¹ and other related parameters. The statistical design was randomized complete blocks (DBCA), the statistical evaluation is based on the analysis of variance (ANOVA) and the Duncan test at 0.05% significance. Based on the results obtained, plant height and number of panicles are negatively associated with the increase in density; the size of panicles and stem diameter show a positive correlation when decreasing density, these parameters showing significant differences; the grain size and weight of 1000 grains showed no significant differences. The possible explanation for these two parameters is that genetic characteristics predominate. Regarding the yield of kg ha -¹ there were significant differences, where the best results were obtained with densities between 400 and 500 thousand plants ha -¹. The possible explanation for these results with the cultivar Salcedo INIA and under sandy soil conditions is that, in the cultivation of quinoa there is competition for water, light and nutrients; where at higher density there is a negative yield response, and conversely at lower density there is not enough grain production to reach maximum yield of kg ha -¹.
