In order to investigate the adaptation of Quinoa, a factorial experiment was conducted in randomized complete block design with three replications at Garmsar Agricultural Research Station in March 2019. In this experiment, the main planting date was at three levels: March 15, March 1 and April 15, and the sub-factor was three genotypes of quinoa. The results showed that the effect of planting date was significant for all studied traits. The effect of genotype on all traits was significant. Regarding the yield, Titicaca (2200 kg / ha) and higher level of index than other genotypes were considered the best time for sowing the area and sowing date of March 15.
