Abstract The cultivation of amaranth in our country has taken great importance due to the existing demand, it is sown under conventional systems existing with a little knowledge about the varieties and the different systems of sowing, in the Ecuadorian sierra the one known as Amaranthus has prevailed. quitensis, so the purpose of the research was to evalúate the yield of two varieties of amaranth (Amaranthus quitensis V1) and (Amaranthus hypochondriacus V2) managing three continuous sowing systems (S1), by stroke (S2) and by transplant (S3). Subsequently, it was determined which of the sowing systems reached higher grain yields in kg / plot. Additionally, plant height (m), diameter of the basal stem (cm), number of panicles per plant at 120, 150 and 180 days at harvest was determined. The variety Amaranthus quitensis H.B.H.B.K. or A. hybridus L. (V1), is known in Ecuador as ataco, sangorache, sangoracha, jataco and currently as black grain amaranth. In the experiment, an experimental design of divided plots with four repetitions and six treatments was applied, analysis of variance was performed; Tukey tests at 5%; and tests of Mínimum Significant Difference at 5% for the factor varieties. The research was carried out in the Experimental Farm Querochaca of the Technical University of Ambato, located in Cevallos, province of Tungurahua-Ecuador. The results stood out in treatment one V1S1, with the following values: the grain yield (GR) was 1.25 g / plot (2480.16 kg / ha); height of the plant (AP) on average 1.56 m; diameter of the basal stem (DDTB) 1.19 cm; number of panicles per plant (NPP) 2.13 and days to harvest (DC) 109.
