The objective of this research was to evaluate the agronomic performance and productivity of sixteen genotypes of Chenopodium quinoa cultivated in agroecological and conventional production systems. The evaluations were carried out, based on agronomic characteristics and yields of sixteen C. quinoa genotypes, grown in two simultaneous experiments, in an agroecological production and a conventional production system carried out at the town of Entre Rios do Oeste, Paraná, Brazil in the harvest 2015/16. Each experiment was composed of three replicates, following the randomized block design. Number of plants in flowering, number of plants per linear meter, height of insertion of the first panicle, number of days for maturation and productivity were the parameters evaluated. The data were submitted to statistical analysis with the aid of the GENES computational application. Genotype Q13-24 showed a more suitable production for the conventional production system. While the genotype Q13-01, presented the increase of productivity, being more indicated to the system of agroecological production. The characteristics height of plant flowers (HPF) and height of insertion of the first panicle (HIP) had higher values when the plants were cultivated in a conventional system. The number of plants per linear meter (NPLM) was higher in the agroecological crop, when compared to conventional cultivation. The same quinoa genotype can behave differently depending on the area management, being a productivity and the genotype cycle depends on the production system and the genotype used.
