“…Bishnoi et al (1978) and Lopetinsky (1991) reported a higher yield for triticale than for other cereal crops, whereas Berkenkamp and Meeres (1987) and Baron et al (1992b) reported that oats yielded more DM ha -1 than either barley or triticale. Similar yields for triticale, barley (Spara et al 1973;Cherney and Marten 1982a;Jedel and Salmon 1994), and oats (Brown and Almodares 1976;Cherney and Marten 1982a) have also been reported. In this study DM yield were 8.1, 7.7, 6.7, and 6.3 t ha -1 for barley/triticale, barley, oats and triticale, respectively.…”

“…The CP concentrations of alfalfa stem and whole-crop alfalfa were significantly higher than the CP concentrations of the cereals, but total CP yield (kg ha -1 ) did not differ among species. Jedel and Salmon (1994) found that due to high biomass production, Cascade monocrops and mixtures with Wapiti triticale had higher CP yields than Wapiti and barley monocrops, but these differences were influenced by season.…”

. 1997. Influence of stage of maturity on yield components and chemical composition of cereal grain silages. Can. J. Anim. Sci. 77: 259-267. The objectives of this study were to determine changes in yield of total grain, stem and leaf DM, leaf:stem ratio and chemical composition during the growth period (boot to softdough stage) and during ensiling of whole-crop barley (Hordeum vulgare L. 'Noble'), oats (Avena sativa L. 'Cascade'), triticale (X Triticosecale Rimpani Witt. 'Wapiti'), and a 1:1 barley (Noble):winter triticale (cv. Pika) mixture. Data for whole-crop cereals were compared with a second cut alfalfa (Medicago sativa L. 'Algonquin'). Crude protein and nitrate concentrations of all crops decreased with advancing maturity. Neutral detergent fiber (NDF), acid detergent fiber (ADF), and cellulose concentrations of all crops initially increased and then decreased with advancing maturity whereas acid detergent lignin (ADL) concentrations increased with advancing maturity. During the growth phase, oats and triticale had higher NDF and ADF concentrations, but by harvesting these differences had disappeared. Leaf as percentage of total DM and leaf:stem ratios were higher and the stem as percentage of total DM was lower for the barley:winter triticale mixture compared with the cereal monocrops. Cereal forages were ranked in order of decreasing quality as barley, barley:winter triticale, triticale, and oats.Key words: Alfalfa, barley, oats, triticale, silage, quality Khorasani, G.

J. Anim. Sci. 77: 259-267. L'objet de nos travaux était de suivre l'évolution du rendement total en grain, en tiges et en feuilles des céréales, ainsi que celle du rapport feuilles-tiges et de la composition chimique durant la période de croissance soit de la fin montaison au stade pâteux mou et durant la conservation en silo. Les céréales plante entière considérées étaient l'orge (Hordeum vulgare L. 'Noble'), l'avoine (Avena sativa L. 'Cascade'), le triticale (X Triticosecale Rimpani Witt. 'Wapiti') et une association à parts égales d'orge (Noble) et de triticale d'hiver (Pika). Les données recueillies étaient comparées à celles d'un premier regain de luzerne (Medicago sativa L. 'Algonquin'). Les concentrations de protéines et de nitrates dans toutes les cultures diminuaient en fonction du degré d'avancement de la végétation. Après une hausse initiale, les concentrations de fibres au détergent neutre (NDF), de lignocellulose (ADF) et de cellulose diminuaient avec l'avancement de la culture alors que les teneurs en LDA (lignine au détergent acide) augmentait régulièrement tout au long de la croissance. Durant la phase de croissance, l'avoine et le triticale révélaient des concentrations de NDF et de lignocellulose plus élevées, mais à la récolte ces différences avaient disparu.

“…More often the yield of a mixture falls between the pure-stand yields of the components and the benefit of mixed cropping can be more difficult to assess. The yield of a mixture can then be compared with mean monoculture yield (Fejer et al 1982, Aufhammer et al 1989, Baron et al 1992, Jedel and Salmon 1994. If the objective of the experiment is not only to compare yields and assess productivity of a mixture but also to study plant competition, the choice of an appropriate design is not simple.…”

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.

, J. 2010. The potential role of annual forage legumes in Canada: A review. Can. J. Plant Sci. 90: 403Á420. The need to reduce agricultural input costs while increasing soil fertility has prompted researchers to look for alternative crop production systems that include N fixing crops. Annual legumes can be used in rotations as forages and green manure crops to increase the organic matter and N content of soils and provide soil cover to control erosion and weeds. Despite the benefits of annual legumes, high production costs and scarcity of seed has hindered their use. Plant Sci. 90: 403Á420. La ne´cessite´de re´duire le couˆt des intrants agricoles tout en rehaussant la fertilite´des sols a incite´les chercheurs a`e´tudier des syste`mes de production de remplacement incluant des cultures fixatrices d'azote. Les le´gumineuses annuelles pourraient eˆtre utilise´es en assolement comme plantes fourrage`res ou comme fourrage vert pour accroıˆtre la concentration de matie`re organique et d'azote dans le sol, et prote´ger celui-ci contre l'e´rosion et les adventices. Malgre´ces avantages, les le´gumineuses annuelles demeurent peu utilise´es en raison de couˆts de production e´leve´s et de la pe´nurie de semences.Mots clé s: Luzerne, tre`fle, vesce, pois, haricot, lentille, rendement fourrager, qualite´du fourrageThe nitrogen-fixing Fabaceae family has been used in crop rotations for centuries (Woll 1915;Semple 1928) to reduce soil erosion, improve soil organic matter and physical properties, help reduce pest damage and contribute N to succeeding crops (Blackshaw et al. 2005). Sometimes crops from this family can be used to supplement perennial pasture, or silage and hay crops. In addition, annual legumes in combination with cereals may play an important role in integrated weed management through plant competition (Schoofs and Entz 2000). However, the practice of incorporating legumes into crop rotations has declined since the development of chemical fertilizers and herbicides (Doran and Smith 1991). The rising cost of fossil fuels needed to produce chemical fertilizers and pesticides, and a greater awareness of the destructive impact of soil erosion and environmental pollution are driving a renewed interest in using annual legumes in agriculture systems in Canada and northern USA. This in turn has prompted researchers to re-examine alternative production systems. Because of the large number of species available, the variation in climate and farming practices, research on annual legumes in Canada and Northern USA has been fragmented. There is a need to explore the integration of these crops in farming systems. This review synthesizes research results on agronomic potential of annual legumes in Canada with particular focus on their use for livestock grazing and feeding, green manure and conservation cover.For convenience, annual legumes can be divided into two groups based on seed size: genera with relatively small or medium-sized seeds such as Medicago, Trifolium, Melilotus, and Lens and those with relatively large seeds...
