CDC Austenson and Claymore displayed the highest of yields, ranging 24-26 bu/acre. These were particularly high when compared to the four least yielding varieties: Gadsby, Amisk, Trochu, and CDC Carter (P=0.001). CDC Carter had the highest test weight among the treatments at 52.5 lbs/bu, while Amisk had lowest at just over 40 lbs/bu (P=0.003). The C.V. in the yield analysis was 24.6, thus the results may not be a proper indicator of true varietal yielding potential. Such lack of confidence was likely due to 2020’s adverse growing conditions.
Yield ranged from 19-31 bushels per acre; test weight ranged from 44-60 lbs per bushel. CDC Fraser and CDC Kindersley yields of 30.5 bu/acre and 29 bu/acre, respectively, exceeded that of the other varieties (P=0.003). For test weight, CDC Clear and CDC Ascent produced significantly higher values than the subsequent 8 varieties (P<0.0001). As with feed barley, a high C.V. value in the yield analysis indicates high levels of variability in the experiment. Thus, yield results can not be considered reliable.
