Adaptation of Some Alternative and Winter Barley Varieties to Erzurum Dry Agricultural Conditions

Abstract

This research was conducted at Atatürk University Plant Production and Research Centre Directorate during the 2017-18 and 2018-19 cropping years, and the adaptation of a total of 60 barley varieties (34 alternative and 26 winter varieties) was examined in Erzurum dry agricultural conditions. According to the average of the cropping years, the vegetative period of the varieties varied between 244.8-255.6 days, the grain-filling period was between 27.0-32.3 days, plant height was 83.8-117.8 cm, the number of spikes per m2 was 375.6-715.0, and the number of grains per spike was 17.8-24.0. Thus, the grain weight was between 34.5-43.4 g, the grain yield was between 225.3-425.1 kg/da, the biological yield was between 874.1-1283.4 kg/da, and the harvest index was between 25.7-37.1%. In terms of the characteristics examined, it was determined that the differences between the varieties and the effect of the cropping seasons on these characteristics were significant. Variety × cropping year interaction was significant for the vegetative period, grain yield, biological yield, and harvest index, except for other characteristics. The highest grain yield was obtained from Olgun variety (425.1 kg/da), followed by Kalaycı-97 (422.2 kg/da), İnce-04 (418.5 kg/da) and Çetin 2000 (418.1 kg/da).
