Atriplex nitens, which can easily grow in arid and saline conditions and produce high amounts of roughage and seed material, has been seen as an important advantage in both closing the forage deficit and bringing marginal areas into production. However, agronomic studies on the plant are limited, and there is no study revealing the effect of inter-row spacing on seed yield. For this purpose, for 2 years (2021-2022), a study was planned to determine the effect of inter-row spacings (22.5, 45.0 and 67.5 cm) on seed yield components in Atriplex nitens grown under unsoiled and rainfall conditions in Iğdır with arid climate. The study was established according to the randomized blocks experimental design with 3 replications. Some parameters showed significant differences according to inter-row spacing. The highest plant height (3.19 m), stem thickness (17.0 mm) and maturation time (192.3 days) were measured in the plots grown with 67.5 cm row spacing, and the highest seed yield (1315 kg/da), the highest stem yield (3970 kg/da) and the highest biological yield (5285 kg/da) in the plots grown with 22.5 cm row spacing. However, harvest index (28.94 - 29.36%) and bracteole thousand grain weight (10.71 - 11.49 g) were determined in the plots grown with 45.0 and 67.5 cm row spacings. When evaluated in terms of years, plant height was high in 2022, while maturation time, pericarp thousand grain weight and harvest index were found to be higher in 2021 when the amount of rainfall was high in the months corresponding to the generative phase of the plants. However, the other parameters examined were not affected by rainfall amounts that vary according to years. [ABSTRACT FROM AUTHOR]

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.
