USA: Montana’s barley varieties performance trials
In 2005, 900000 of barley were planted in Montana averaging 56 bushels per acre of yield producing a total of 39.2 million bushels. In USA, Montana ranked third in overall production of barley and second in total dollar value of barley. Harrington was the leading variety in Montana with 28.3 % of the acres planted, followed by Haybet on 17.2 %, AC Metcalfe on 8.7 %, B1202 on 5.0 % and B Merit on 5.0 % of total acres, according to a report from Prairiestar.

Baronesse, Calgary, Eslick, Gallatin, Haxby, Valier, WestBred Xena and WestBred Boulder are two row feed barleys while Hays is a two row hooded hay barley. Harrington, Merit and Conlon are two rowed malt barleys while Legacy, Morex and Tradition are six row malt barleys. All of the malt varieties are currently recommended by the American Malt Barley Association for malt production except for Morex.

Under irrigation from 1999-2005 WestBred Xena (130.2), Eslick (129.1), Calgary (128.1), Baronesse (126.8), Haxby (126.6), and WestBred Boulder (126.6 bu/ac) were the highest yielding varieties.
