Abstract

There is increasing use of barley (Hordeum vulgare L.) forage for swath grazing, bale grazing and silage for back grounding and finishing beef cattle in western Canada. Twelve barley varieties (6 two row and 6 six row) were compared in field trials in the Peace Region of Alberta, from 2009 to 2011, to identify the varieties with superior forage yield and nutritive value. Forage yield dry matter (DM) yield was greatest for Busby, followed by Ponoka, CDC Cowboy, Seebe, CDC Austenson, Vivar, Chigwell, Sundre, Xena, Trochu, AC Lacombe, and AC Ranger. Eight varieties had > 8.0 t ha^-1 DM yield, five of which belonged to the two-row barley. The crude protein (CP) content varied from 8.70% for Busby to 10.4% for Seebe. Based on high CP content and low detergent fiber contents, CDC Austenson, Chigwell and Ponoka were the top three varieties. Two of the top three varieties for both forage yield and nutritive value were the two-row type, an indication that the two-row barley type may be better adapted for forage production in this environment. The top rated varieties may therefore be chosen for silage, green feed or swath grazing system in the Peace Region environs.
