Abstract:
Timothy (Phleum pratense L.) and Italian and Westerwolds ryegrasses (Lolium multiflorum Lam.) were harvested as first-cut wilted silages in 1979 and 1980 and were compared on the basis of composition, intake and digestibility. Timothy silage had more cell wall content and was less digestible than the annual ryegrass silages in both years (P < 0.05). Seeding year timothy was consumed less than Aubade ryegrass in 1979 but the postseeding year timothy silage was equal in intake to 1980 Aubade silage but inferior to Italian ryegrass in digestible protein content and also intake (P < 0.05). Leafier Italian and Promenade ryegrasses were consumed more than the stemmy Aubade ryegrass (P < 0.05). Annual ryegrasses were not significantly different in their composition during 1979 but in 1980, Italian ryegrass contained less cell wall and was more digestible than Aubade ryegrass silage (P < 0.05). Prolonged field wilting in humid weather appeared to be more detrimental to the stemmy Aubade for intake and feed value than to the leafier Promenade and Italian ryegrasses. Seeding year timothy silage had lower feed value than the postseed year timothy silage.Key words: Silage, timothy, annual ryegrass, intake, digestibility, composition

Abstract:
Italian ryegrasses, cultivars Barmultra and Lemtal, and Westerwolds ryegrasses, cultivars Barspectra, Merwester and Promenade, (Lolium multiflorum Lam.) were harvested as first- and second-cut herbages and compared for yield, leafiness and water-soluble carbohydrate content during the 2-yr study. These herbages were conserved as silages and compared for chemical composition and for intake, digestibility, and total-N retention in sheep. First-cut ryegrass yielded more dry matter than second-cut ryegrass (3.3 vs. 2.6 t ha−1). First-cut ryegrass silages contained less dry matter and NDF, and sheep consumed less, but digested better and retained less total-N in comparison with second-cut ryegrass silage. Italian ryegrasses yielded less dry matter, were more leafy, contained less ADF, and were better digested compared with the Westerwolds ryegrasses. The herbage content of water-soluble-N, and the ratio of ammonium-N to total-N in silage were not different between the ryegrasses. Italian Barmultra was more leafy than Lemtal cultivar but no other significant differences were measured between these cultivars. Westerwolds Merwester yielded more dry matter, was less leafy, contained more NDF and ADF, and had lower voluntary intake, digestibility, and its total-N was less retained in sheep as compared with the Barspectra or Promenade Westerwolds ryegrass. Italian ryegrasses were superior in composition, voluntary intake, and digestibility to Westerwolds, but the latter were superior on the basis of yielding ability and efficiency of total-N utilization in sheep.Key words: Silage, ryegrass, intake, digestion, composition, Nitrogen retention

Abstract:
Introduced Lolium grasses are utilised in Japan for forage, turf and soil conservation. Many of these grasses have become naturalised in disturbed ecosystems. Neotyphodium endophytes in the tissues of grasses can increase host fitness by increasing tolerance to both biotic and abiotic stresses. Consequently, endophyte infection may be a factor enhancing invasion success of exotic grasses in the Japanese islands. We detected infection by Neotyphodium endophytes in 162 of 173 naturalised ryegrass populations in Japan. Italian ryegrass (L. multiflorum) had a higher infection rate than perennial ryegrass (L. perenne). Italian ryegrass also exhibited geographic variation in infection rate. It is unlikely that the infected Italian ryegrasses found in this study have come from cultivars used in meadows, since the use of forage ryegrass cultivars infected with Neotyphodium endophytes has been restricted in Japan to prevent toxicity problems. Possible sources of the ryegrasses may be turf seeds, soil conservation materials and/or contaminants in imported plant materials.

Abstract:
Abstract Argentine stem weevil (ASW) is a highly destructive pest of ryegrass that has recently been associated with increased incidences of field damage. A survey of farmer awareness and management practices in relation to this pest was carried out. Many (47%) farmers sowed favoured plant hosts such as short-term and tetraploid ryegrasses. A field trial, undertaken near Hamilton, compared the effects on ASW larval damage of 10 different ryegrass/endophyte associations in comparison with an endophyte-free control with and without seed treatment. U2 endophyte in a diploid perennial festulolium and AR37 endophyte in a hybrid tetraploid, an Italian diploid and a tetraploid perennial ryegrass had significantly less damage (42%). NEA2 endophyte in a diploid perennial ryegrass and AR1 endophyte in short-term ryegrasses failed to protect plants from severe damage by this pest. Farmers need to be aware of the risks of ASW damage to short-term and tetraploid ryegrasses. Keywords: ploidy, short-term ryegrasses, larval damage, endophyte strains, pasture management

Abstract:
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

Abstract:
Accessions of Victorian perennial ryegrass (Lolium perenne L.) grown as turfs were inferior to or no better than European and North American ryegrasses developed specifically for turf. This applied to all aspects of their growth, except those of germination (which was faster, especially at temperatures around 12�C), thatch accumulation (which was less), and in their possession of an entophytic fungus, Acremonium loliae, which in the longer term could be associated with greater persistence. At the seedling stage, Victorian and turf ryegrasses produced similar dry weights, but the Victorian ryegrasses had fewer, larger leaves and tillers. Victorian ryegrass turf swards had lower tiller densities and standing dry weights, yet produced more clippings. The total production of Victorian ryegrass turfs was less than that of the turf ryegrasses. There were no differences in the seasonality of growth. In spring, flowering heads were more common in Victorian ryegrass turfs and the leaves of these turfs also shred more when mown. During the first year of turf growth, differential selection occurred in favour of plants that were prostrate, had shorter leaf sheaths, were later flowering, and that contained endophyte. The direction of selection confirmed the functional significance of observed differences between pasture and turf ryegrasses.

Abstract:
Italian (Lolium multiflorum) and short-term hybrid ryegrasses (L. boucheanum) are utilised by farmers for their reliable establishment and yield potential for winter feeding, but lack summer production and persistence. To improve the performance of these ryegrasses, endophyte (Neotyphodium lolii) strains from perennial ryegrass were inoculated into several cultivars and evaluated for agronomic performance in the Northland region of New Zealand. 'Moata' tetraploid Italian ryegrass families usually showed a reduction in yield when infected with the AR5 strain compared with endophyte-free Moata. Infection of the Italian ryegrass cultivars 'Corvette' and 'Status' with the N. lolii endophytes strains, AR1 and more particularly AR37, usually increased plant production and persistence. Natural infection with the N. occultans endophyte also improved plant performance. Improved plant performance was most closely associated with reduced damage from African black beetle. Interactions between plant line/cultivar and endophyte strain offer the potential for plant breeders to provide enhanced endophyte-infected cultivars of Italian ryegrasses to farmers.

Abstract:
Perennial ryegrass varieties bred to express high water-soluble carbohydrate (WSC) concentrations have been shown to improve liveweight gain in pre-weaned lambs of grazing ewes (Lee et al., 2001) compared to conventional ryegrass. Studies have shown that the largest differential in WSC between ryegrass varieties bred for high WSC concentrations and control ryegrasses occurs 5-6 weeks after the plant is allowed to re-grow following cutting or grazing (Miller et al., 2001). Therefore, the benefits, in terms of lamb performance, of using these grasses with high WSC concentrations may be best achieved when they are rotationally rather than continuously grazed. The aim of this experiment was to compare lambs rotationally or continuously grazing either a ryegrass variety bred for high WSC concentrations or a control ryegrass.

Full text
Abstract:
The growth, persistence, and rust sensitivity of a range of temperate grasses were measured to assess their potential for irrigated pastures in the subtropics. Characteristics considered important for adaptation to the subtropics include a relatively even growth rate throughout the year, rust tolerance, and the ability to persist under humid conditions. Cultivars and experimental lines from Lolium perenne (perennial ryegrass), L. rnultiflorum (Italian ryegrass), Festuca arundiizacea (fescue), Festuca x Lolium (festulolium), Bromus spp. (prairie grass and bromes), Dactylis glomerata (cocksfoot), and Phalaris aquatica (phalaris) were sown at Gatton, south-eastern Queensland, in pure stands or mixtures of annual and perennial grasses, using high seeding rates, 50 kg N/ha.defoliation, and full irrigation throughout the year. As a group, the fescues were the highest yielding and most persistent over 2 years, with AU Triumph the highest yielding cultivar. Maru phalaris was the most persistent grass, increasing from a frequency of 85% at the end of the first year to 100% at the end of the second year. Perennial ryegrass yields were about two-thirds those of the fescues, with a frequency of around 70% after 2 years. Dobson was the best ryegrass, producing a greater proportion of its forage in summer and increasing its density over the 2 years compared with the other perennial ryegrasses. Mixtures of annual ryegrass and fescue cultivars produced yields equivalent to pure fescue swards, with production dominated by annual ryegrass in the first year and by fescue in the second. Matua prairie grass was high yielding, but under frequent cutting was not as persistent as the ryegrasses. Felopa festulolium was inferior to the perennial ryegrasses and fescues in yield, the distribution of that yield, and persistence. Weeds contributed 1-10% of total yield over 2 years. The experiment suggests that the fescue cultivars are the most productive temperate grasses for perennial irrigated pastures in the subtropics, although better animal performance would improve farmer acceptance. The addition of a ryegrass component to fescue swards increased yields during establishment but did not improve overall yields. Late-maturing cultivars are the highest yielding of the perennial ryegrasses. Rust sensitivity needs improvement as all the present lines are highly susceptible.

Abstract:
A field test was conducted to evaluate the turf performance of improved hybrid ryegrass (sometimes called intermediate ryegrass) Lolium hybridum versus that of perennial ryegrass germplasm (Lolium perenne) for winter overseeding purposes. "Gulf" annual ryegrass was also evaluated for comparison purposes. On all evaluation dates, the treatment effect was significant for all visual response variables measured (quality, color, texture, density, etc.). The mixture of LHRT hybrid ryegrass/Poa trivialis established quicker than other treatments during the first month (November). Perennial ryegrass entries provided the darkest color turf. Among hybrid ryegrasses, Pick A-97 was slightly darker in turf color when compared to LHRT. LHRT alone was darker in color than when mixed with Poa trivialis. In terms of overall turf quality, Pick A-97 and LHRT hybrid ryegrasses were essentially equal in performance. The spring decline was greater among hybrid ryegrasses than that of perennial ryegrass. Both hybrid ryegrasses (A-97 and LHRT) were superior to annual ryegrasses in all aspects of turf performance. By mid-June of 1999, Pick A-97 had more bermudagrass present (52%) than LHRT (28%). LHRT had more straw-colored (dead transition grass) than A-97 as well. By early July, A-97 and LHRT had 72% and 62% bermudagrass, respectively, and essentially the same amount of overseed present (20-23%). LHRT had 15% plot straw at this time, while A-97 had 8%. Among perennial ryegrasses, Sunshine had the slowest transition (42%), followed by Jiffie (50%) and Future 2500 (71%) by early July. The addition of Poa trivialis to LHRT hybrid ryegrass increased overall quality of the LHRT alone, but slowed transition slightly, most likely due to increased canopy densities achieved by the addition of Poa trivialis. This test demonstrated that the hybrid ryegrass germplasm tested here provided adequate fairway turf performance, and that transition among and between Lolium germplasm is variable, and genetically dependant.

Abstract:
Thirteen herbicide treatments were applied on May 8, 2006, on a golf course fairway to assess transition and turf quality effects. Initial injury to perennial ryegrass was most extreme for Tranxit GTA when applied at 1.0 oz/prod/acre and Katana applied at 2.0 oz/prod/acre. Katana resulted in the total elimination of ryegrass and resulted in a fully necrotic canopy (straw cover) within two weeks after application to July 19, 2006 (72 Days after treatment). The development and persistence of necrotic leaf tissue of perennial ryegrass (straw) had the greatest impact on decreasing overall turfgrass quality ratings. No treatment went through the summer without some loss of quality at some point, including the untreated control. Certainty had little or no effect on transition when applied once at the rate of 1.25 oz/prod/acre. Surflan was not effective in ryegrass transition. The tank mix of Transit and nicosulfuron applied at the rate of 0.25 oz/prod./A each, produced an enhanced transition with nominal quality. In similar fashion, Monument applied at 0.35 oz./A produced an enhanced transition with nominal quality. A rates used in this test, other treatments had either too slow of a transition or had poor and extended low quality turf scores from rapid development of dead ryegrass (straw) and subsequent slow bermudagrass re-establishment. The UTC turf maintained a high percentage of living green ryegrass into the summer and 20% live ryegrass on August 8, 2006 which is roughly six weeks before the next overseeding.

Abstract:
Higher seeding rates and larger seed sizes could enhance the competitiveness of wheat with ryegrass. Growth room and field research evaluated the effects of wheat seeding rates and seed size in competition with Italian ryegrass. Winter wheat seeds cultivar “Ogallala” were divided into three seed sizes: small seed passed through a sieve with 2.08mm round holes, large seed which did not pass through a sieve with 3.18mm round holes, and bulk seed directly from a commercial seed bag. These wheat seed and seed of the Italian ryegrass cultivar AGulf@ were planted in plastic pots containing fritted clay. A replacement series design with 12 plants per pot compared the relative growth in pure culture and competitiveness in mixtures of the two species. The planting proportions of each wheat seed group and ryegrass were 100% and 0%, 50% and 50%, and 0% and 100%, respectively. Wheat seed size did not affect the growth of the wheat plants in pure culture. Wheat seed size did not affect competitiveness with ryegrass. There were no differences related to seed size among the pure or mixed cultures of wheat. The failure of increased wheat seed size to affect competition with ryegrass may be the result of the relative seed size difference between the two species. Even the small wheat seed in this study were almost 9-fold greater inweight than the ryegrass seed. Field experiments conducted for two years from fall 2002 through spring 2004 at the Texas A&M University Agronomy Farm measured wheat yields at the same three wheat seed sizes, two wheat densities of 250 plants m-2 and 400 plants m-2, and three ryegrass densities of 0, 100 and 200 plants m-2. Small, bulk, and large wheat seed produced similar yields in both years: one season favorable (2003) for growth and the other (2004) unfavorable. Thus, seed size in the field under favorable or unfavorable conditions or in the growth room experiment did not affect the competitiveness of wheat in the presence of ryegrass. Increasing the wheat plant population from 250 to 400 plants m-2 in the field also failed to enhance the competitiveness of wheat in either year.

Abstract:
Based on the new methodological approaches, an economic assessment of feed production using promising pasture grass stands with the participation of domestic varieties such as Karat ryegrass and VIK 90 festulolium was made. The feed production using long-term pasture grass stands amounted to 6.1 thousand feeds. units/ha at a cost of 4.8 rubles. per feed unit, which is 2.3 times lower than the price of feed oats.
