“…(1992) The DM yields of the mixtures generally did not differ from their higher yielding monocrop (Table 3). A similar pattern was found by Fejer et al (1982) for cereal grain yields; however, Baron et al (1992) found that mixtures with winter cereals were lower yielding than their higher yielding monocrop. The A:E ratios for DM yields were often higher than 100% especially in 1989 and 1990 (data not presented For personal use only.…”

The research assesses the productivity of mixture of oats (Avena sativa) and wheat (Triticum aestivum), and compares two different approaches used in plant competition studies: replacement (substitutive) designs and additive designs. The experiment was carried out on sandy loam soil at the Experimental Station of Agricultural University of Wrocław (Poland). Oats and wheat were grown for grain as sole crops and in 1 : 1 replacement mixtures at three rates of seeding: 150, 300 and 600 viable seeds m )2 . These designs allowed mixtures seeded at a rate of 300 and 600 seeds m )2 to be analysed according to either a replacement or an additive approach. In 1999, pure stand wheat and oats-wheat mixture yielded significantly more grain than oats grown alone but in 2000 there was no difference in yield. Wheat outcompeted oats in mixture but the relative competitive ability of the two species changed little with increasing seeding density. Relative yield total (RYT) for grain was significantly >1.0 (RYT ¼ 1.07) in 1999 for the lowest seeding density, showing partial complementarity in use of limiting resources by the species in mixture. Based on grain yields, the results obtained from substitutive and additive mixtures were similar with respect to the relative yields and relative competitive ability of the two species concerned.

“…Interspecific mixtures are used throughout the world for grain and forage production, often because of an assumed advantage over monocrops. In Ontario, Fejer et al (1982) reported that although grain yield of barley–oat mixtures did not exceed the higher‐yielding monocrop, 50% of the barley and oat production occurred as mixtures. Intraspecific mixtures may be composed of cultivars of the same species, multilines, or bulk hybrids.…”

1990; Jedel et al., 1998), wheat (Triticum aestivum L.) mixtures (Khalifa and Qualset, 1974; Tapaswi et al., Morphological and physiological differences in competitive ability 1991), and barley-oat mixtures (Taylor, 1978; Fejer et among species and genotypes can affect the growth, development, and subsequent composition and value of feedstuffs produced from al., 1982). Change in the composition of mixtures means small grain cereal mixtures. Our objective was determine the final that for specific uses they may need to be reconstituted grain yields of the components of mixtures and compare these yields on a regular basis. The change is attributed to differwith those expected based on the yields of the monocrops. Three ences in competitive ability between genotypes. field studies were conducted to evaluate the productivity of barley Blijenberg and Sneep (1975) found that competitive (Hordeum vulgare L.), oat (Avena sativa L.), triticale (ϫ Triticosecale ability of seven of eight cultivars of barley was related rimpaui Wittm.), and rye (Secale cereale L.) grown as monocrops to their yielding ability in monocultures. For triticale and mixtures. Seeding rates ranging from 250 seeds m Ϫ2 to 750 seeds mixtures, Mergoum et al. (1998) found that the compom Ϫ2 were evaluated to determine their effect on competitive ability nent with the best "mixing ability" or contribution to of genotypes and species of small grains. Differences in competitive grain yield of the mixture was the highest-yielding tritiability were found. The semi-dwarf barley 'Kasota' was less competitive than the standard-height 'AC Lacombe' and 'Seebe'. 'Noble'cale advanced line in their test. However, Jokinen barley was more competitive than 'AC Mustang' oat or 'Wapiti' triti- (1991a, 1991b) and Jedel et al. (1998) found that competcale. 'Prima' winter rye was more competitive than 'Pika' winter itive ability in barley was not related to yield potential triticale. Relative grain yields were generally not different than 1.0 of the monocrops. Valentine (1982) found that a barley g g Ϫ1 , but when significantly different they were usually higher than genotype with erect growth habit had the competitive one, indicating that the yields of those mixtures were better than edge over a prostrate, short genotype. Jedel et al. (1998) expected based on yields when the cultivars were grown as pure found that for barley, the tallest cultivar in mixtures stands. Seeding rates had little effect on competitive ability. The was dominant in four of six location-years. However, specific factors that lead to better than expected grain yields of mixheight alone did not explain competitive ability, as the tures and to good competitive ability of cultivars and species are semi-dwarf cultivar was also highly competitive. Comdifficult to predict and must be evaluated on a case-by-case basis.
