Tests were conducted at Lacombe, AB, from 1989 to 1991 to determine the forage yield and quality of Wapiti triticale (× Triticosecale Rimpani Witt.) grown as a monocrop and in binary mixtures with Cascade oat (Avena sativa L.), Empress barley (Hordeum vulgare L.) or Johnston barley. The Cascade monocrop and mixtures with Wapiti had the highest DM yields (12.37–13.42 t ha−1). Yields of the barley monocrops and mixtures with Wapiti (6.60–9.10 t ha−1 in 1989 and 8.96–11.49 t ha−1 in 1990) were similar to the Wapiti monocrop (8.06 and 8.99 t ha−1). In 1991, yields for the Wapiti monocrop and 25:75 barley:Wapiti mixtures (14.54 and 14.99 t ha−1, respectively) were higher than those for the barley monocrops and 50:50 and 75:25 mixtures (11.98–12.79 t ha−1). The yields of the mixtures in 1989 and 1990 were 108 and 106% higher than expected based on the yield of the components, although in 1991 this enhancement was not observed. Moisture contents at harvest were variable and not always as expected based on the relative maturities of the species. However, mixtures with Wapiti could offer some flexibility in harvest for silage production. Protein contents were found to be highly variable and no trends were established. The Cascade monocrop and mixtures had the highest protein yields in 1990 and 1991. The acid detergent fibre (ADF) contents of the 50:50 and 25:75 Cascade:Wapiti mixtures (26.9 and 28.4 g 100 g−1) were lower than the Cascade monocrop (33.6 g 100 g−1). Lignin contents were found to vary between treatments only in 1989 when the Wapiti monocrop (3.90 g 100 g−1) was intermediate to the Empress (3.30 g 100 g−1) and Cascade (4.83 g 100 g−1). Yield stability and quality would make use of Wapiti mixtures for silage attractive choices for silage production. Key words: Silage, protein, ADF, lignin, cereal mixtures

Three spring barley (Hordeum vulgare L.) and four annual ryegrass (Lolium multiflorum Lam.) types were intercropped to evaluate the potential yield and quality of forage which can be produced under irrigation in southern interior B.C. All treatments were intercrops; when barley cultivar effects are described they are averaged over the ryegrasses and vice versa. Barley cultivars differed in grain maturity. Ryegrass cultivars included diploid and tertraploid Italian and Westerwolds types. Intercrops including late grain maturing barley cultivars (Samson and Virden) increased the yield of the first silage cut (both by 25% over 2 yr) compared to Diamond, a medium-maturing cultivar adapted to the area. Intercrops containing the semi-dwarf barley, Samson, produced more digestible forage including higher in vitro digestible dry matter (IVDDM) and lower ADF and lignin. Annual ryegrass yield in the first cut intercropped with Samson was almost twice that with either Diamond or Virden, showing that Samson barley is less competitive. Second-cut yield (ryegrass regrowth) was greater for tetraploid than diploid annual ryegrasses. Yields of fall pasture (cuts 3 and 4) were similar among ryegrass cultivars. Cuts 2 and 3 (ryegrass only) of Italian ryegrasses had superior quality (higher IVDDM and protein; and lower ADF, lignin, and NDF) to Westerwolds ryegrassses, but all cultivars had similar quality in the late fall (Cut 4). It was concluded that a range of barley and annual ryegrass cultivars can be successfully intercropped to produce forage in south central B.C.Key words: Intercropping, barley annual ryegrass, forage yield and quality

SUMMARYA study, conducted in the Peace region of Canada, determined the effects of the stand and management treatments of four herbage experiments (1986–88) on the yield and quality of subsequent crops of barley (Hordeum vulgare L.) harvested in 1989 and 1990. Quantitative relationships indicated that the crop management treatments most conducive to good yield and quality of herbage were also the most beneficial for subsequent high yield and quality of the barley grain. Unless designs orthogonal to those previously used can be found, covariance adjustment procedures are recommended to minimize the residual effects of previous experiments.

The changing climate, water scarcity, reduction in the land area under forage crops, expanding ruminant population, burgeoning demands for milk and meat production and food security concerns all insist on a necessary increase in forage production and quality. Cereal–legume mixed intercropping offers a biologically superior option to boost herbage yield and quality of preserved fodder (hay and silage), provided that rationalization of the component crop’s proportional ratio is performed. Therefore, the current study was conducted to determine the forage yield and quality of barley (Hordeum vulgare L.) and pea (Pisum sativum L.) mixtures at the ratios 100:0, 75:25, 50:50, 25:75 and 0:100. The experiment was laid out in the regular arrangement of a randomized complete block design with three replicates. The results exhibited that forage quality was significantly affected by the mixture ratio. There was a significant improvement in protein, fiber rate and digestibility from the mixture. The ratios of barley and pea with 50:50 and 25:75 produced the maximum productivity and the best quality of forage. Regarding forage preservation, silage recorded higher contents of crude protein, ash and lower fiber contents than hay. Among seed mixtures, 0:100 ratio of barley–pea yielded the highest quality of silage with the maximum crude protein, ash and digestibility with lowest fiber contents.

Sphagnum peat is an abundant resource in the Quebec boreal zone and can be used to improve water retention in sandy soils of low productivity. Our objective was to select a peat application rate suitable for growing potato (Solanum tuberosum L. 'Superior') and barley (Hordeum vulgare L. 'Chapais') on a ferro-humic podzol. The experiment was conducted in Mistassini, Quebec, from 1994 to 1997. Organic matter content (OMC) of a Parent loamy sand was 2.7–2.9% initially. Peat was applied to small plots in a 2-yr potato and 2-yr barley rotation at rates of 0 (control), 29, 48 and 68 t ha−1 on a dry weight basis. A cupric fertilizer trial (0 vs. 2.2 kg Cu ha−1) was combined with the peat treatments. A yearly potato–barley rotation was also established in a nearby field receiving 25 t peat ha−1. The arable layer of peat-amended soils was stratified into a 5.3- to 14.8-cm thick upper layer (A1) down to the limit of peat incorporation, and an underlying layer (A2), averaging 15 cm in thickness, keeping the original soil properties. The highest tuber yield, but reduced tuber specific gravity, were obtained with the 48 t ha−1 treatment compared with the control and the 29 t ha−1 treatments. Peat rates excceeding 29 t ha−1 reduced yield and quality of the barley crop. The Cu concentration in barley and potato diagnostic tissues decreased as peat rate increased. Copper was needed to counteract the detrimental effects of peat amendments on maturation, yield and quality of barley. At field scale, peat increased the lower limit of soil water content for starting irrigation from 0.12 m3m−3 in the control to 0.15 m3m−3 in the peat-amended soil. Irrigation rate should be augmented at each passage, and frequency of waterings diminished, in peat-amended soils compared with the control, due to increased water storage capacity. Peat improved the productivity of the sandy soil up to 4–5% OMC, but could induce Cu shortage in barley. Key words: Soil water, potato, Solanum tuberosum L., barley, Hordeum vulgare L.

Field studies were conducted on three southwestern Quebec soils for 2 yr to provide information on effects of S fertilization on barley growth, to examine any S-P interaction, and to assess contributions of S from rain during the growing season. The treatments were arranged in a factorial combination of four levels of S (0, 15.6 or 31.2, 62.4 and 93.6 kg S/ha) with three levels of P (0, 117 and 234 kg P2O5/ha) added as gypsum and triple superphosphate, respectively. The results showed that added S either had an inconsistent effect or no effect on barley yield on the experimental soils. The lack of response was attributed to annual S additions from rain estimated to be in excess of 10 kg S∙ha−1∙yr−1, as well as high levels of available S in the soils. No S-P interaction was observed, indicating that high P fertilization should not result in S deficiencies for barley in southwestern Quebec.

Application of N fertilizer in the fall as opposed to spring has been a controversial recommendation for cereal crops grown in Western Canada. Also, oilseed crops such as rapeseed may not respond to N in the same way as cereals. To investigate spring and fall application of N on barley and rapeseed, factorial split plot experiments were designed with three N treatments of 45, 90 and 134 kg N ha−1 and four P treatments of 0, 9.4, 18.8 and 28.2 kg P ha−1, as main plots. A control without fertilizer was included and the subplots were spring and fall times of broadcast application of ammonium nitrate fertilizer. Barley (Hordeum vulgare L.), cultivar Conquest and rapeseed (Brassica campestris L.) cultivar Arlo were seeded as the test crops over a 5-yr period and a 6-yr period, respectively, at separate sites on Melfort silty clay soil to determine the differences in yield and quality of grain between spring and fall applied N. In some years yield response to N fertilizer was greater when applied in the spring and in other years when applied in the fall, resulting in a significant time of N × year interaction effect on yield. However, on the average, there was no significant difference in yield of barley or rapeseed grain between fall and spring applied N, 3.51 vs. 3.59 and 1.39 vs. 1.41 t ha−1, respectively. Nitrogen and P fertilizer increased yield as much as 2.17 t of barley and 0.76 t of rapeseed ha−1 although the concentration of mineralized ammonium- and nitrate-N in the soil was rated medium according to provincial soil test standards. The difference in yield response of barley (Y, t ha−1) between spring and fall applied N among years was related to the rainfall (X, mm) in May by the equation:[Formula: see text]and for rapeseed:[Formula: see text]Because N was applied relatively late in the fall, the available soil N was medium and the conditions for N loss in these experiments minimal, differences in barley and rapeseed yield response to N fertilizer between spring and fall applied N were small. When P fertilizer was applied at a heavy rate, fall application of N produced a higher yield of rapeseed than spring application in all years.
