ABSTRACT: 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.
