The Battle River Research Group (BRRG) has participated in the provincial Regional Variety Trials (RVT’s) since 1998, and currently conducts extension programs in the counties of Beaver, Camrose, Flagstaff, Stettler and Paintearth.
In 2012, the BRRG established barley demonstrations 16 kilometres east of Castor and eight kilometres north of Viking. The soil at Viking is thin black, while the Castor soil is in a transition area from thin black to dark brown. Varieties featured were two-row feeds, two-row malts and six-row feeds.
The summer of 2012 was abnormally warm, humid and wet. Approximate precipitation from April to August was 400 mm at Viking and 360 mm at Castor. This followed the wet years of 2010 and 2011, and a winter with higher-than-normal snowfall. A heat wave in early July hurt the yield potential of many crops, including barley.
The best yields were realized at Viking, with an average of 87 bushels per acre. The top two-row variety was Gadsby at 92.3 bu/ac, while CDC Copeland’s 90.2 bu/ac was the best performer among two-row malts.
Only two six-row varieties were tested. Vivar yielded 89.4 bu/ac, followed by Trochu at 87.4 bu/ac.
Results from Castor could not be published as the trial was damaged by a hailstorm in July—the average yield was only 36 bu/ac.
