摘要

The inclusion of forage pea ( L.) in mixtures with forage barley ( L.) or oat ( L.) for greenfeed or silage production is gaining interest in western Canada. A twelve-different combination of monocultures and mixtures were evaluated for forage dry matter (DM) yield and forage quality in three soil zones of Saskatchewan for 2 years. Forage pea cvs. ‘CDC Horizon’ and ‘40-10’, barley cv. ‘CDC Maverick,’ and oat cv. ‘CDC Haymaker’ were used in the study. Treatments were allocated in a split-plot in RCBD with nitrogen fertilizer treatment (25 vs. 60kg ha ) as main plot, and mixtures (at 100, 100:30 and 50:50% of normal seeding rate) as a subplot, with 4 replications. Plots were harvested on the maturity of the cereal in the mixture. Data were analyzed using the PROC MIXED of SAS. Year, site, nitrogen treatment, mixtures and their interactions were fixed effects; block, block, and nitrogen treatment interaction were random effects. Nitrogen fertilizer treatment did not affect DM ( =0.33), and contents of CP ( =0.25), ADF ( =0.78), NDF ( 0.73) and starch ( =0.41). Average DM yield for mixtures was significantly ( -1), intermediate in Dark Brown soil (8778 kg ha ), and lowest in Brown soil zones (7156 kg ha ). CP concentration was significant ( -1 (barley) to 137 g kg (pea). Pea-cereal mixture had 25% more CP than that monoculture cereal stands. ADF and NDF concentration for mixtures averaged 316 and 530 g kg , respectively. Starch content ranged from 31.6 (7) to 53.4 g kg (3), with an average of 40.4g kg .The pea-cereal mixture productivity varied soil zones but generally produced similar or fewer yields with greater forage quality than monocultures.
