This study was carried out in Iğdır ecological conditions for two years (2019-2020) in order to determine the effects of different sowing times on the seed yield of mountain spinach. In the study, the effects of different sowing times on the plant height, number of branches, stem diameters, maturation time, biological yield, stem yield, harvest index, seed yield and thousand grain weight of mountain spinach were determined. The research was carried out in dry conditions with three replications according to the randomized blocks experimental design. The effect of sowing times (except thousand grain weight) on the parameters examined in the study was found to be statistically significant. Delaying the sowing time caused significant decreases in the investigated parameters. When evaluated in terms of years, plant height, number of branches, maturation time and thousand grain weight were found to be statistically significant, and these values (except thousand grain weight) in the rainy 2020 year were higher than in 2019. According to the two-year average results, the highest stem yield (3541.5 kg/da), seed yield (1586.6 kg/da) and biological yield (5128.1 kg/da) were obtained from sowing in mid-March, which is the first sowing time
