This research was carried out to investigate the adaptability abilities of some barley varieties in Van ecological conditions in the winter growing season of 2020-2021. Sixteen genotypes were grown according to randomized block design with three replications. The quantity of supplemental irrigation was equivalent to a total precipitation of 114 mm. According to the results obtained, the number of days to spike was 167.67-175.66 days, plant height 63.37-91.85 cm, number of spikes per square meter 403.67-619.67, lodging 0-10%, chlorophyll ​​​​45.34- 53.09 SPAD units, maturity period 36.0-36.7 days, canopy temperature 30.0-30.4 oC, spike length 7.30-9.96 cm, number of spikelets per spike 33.8-21.7, number of fertile spikelets 7.13-15.73, thousand grain weight 36.67-45.83 g, hectolitre weight 62.30 – 66.10 kg/hl, biological yield ​​20.36-20.45 t/ha, and grain yield 3.08–6.98 t/ha. The highest grain yield was obtained from two row barley varieties; Calabey, Akar, Tosunpasa and Asil. The highest biological yield was measured in Anka-11 and Aydanhanim cultivars.
