Hordeum vulgare L.), oat (Avena sativa L.), triticale (×Triticosecale rimpaui Wittm.), and rye (Secale cereale L.) grown as monocrops and mixtures. Seeding rates ranging from 250 seeds m−2 to 750 seeds m−2 were evaluated to determine their effect on competitive ability of genotypes and species of small grains. Differences in competitive ability were found. The semi-dwarf barley `Kasota' was less competitive than the standard-height `AC Lacombe' and `Seebe'. `Noble' barley was more competitive than `AC Mustang' oat or `Wapiti' triticale. `Prima' winter rye was more competitive than `Pika' winter triticale. Relative grain yields were generally not different than 1.0 g g−1, but when significantly different they were usually higher than one, indicating that the yields of those mixtures were better than expected based on yields when the cultivars were grown as pure stands. Seeding rates had little effect on competitive ability. The specific factors that lead to better than expected grain yields of mixtures and to good competitive ability of cultivars and species are difficult to predict and must be evaluated on a case-by-case basis.
