• Strengths

  Easily established Highly productive and nutritious under grazing Moderate winter and summer growth Rapid regrowth

• Limitations

  Requires moderate to high soil fertility Does not withstand heavy grazing pressure through drought Susceptible to cockchafer and cricket damage Standard endophyte can cause stock health issues

• Plant Description
  Plant

  Densely tufted, multi-tillered perennial with fibrous root system.

  Stems

  30 to 90 centimetres.

  Leaves

  Fine (approximately equal to 7 millimetres), dark green, hairless, under surface shiny, blade folded about mid-rib in young shoot, leaf-base usually dark red.

  Leaflets

  Spike approximately equal to 20 centimetres, spikelet usually greater than 10 florets/spikelet; awnless lemma.

  Seedhead

  Spike approximately equal to 20 centimetres, spikelet usually greater than 10 florets/spikelet; awnless lemma.

  Seeds

  Fawn, flat, awnless, approximately equal to 6 millimetres long. Approximately equal to 520,000 per kilogram (diploid cvv).

• Pasture Type And Use

  Grazing and fodder conservation. Most widely sown pasture grass in temperate regions.

• Rainfall

  Greater than 550 millimetres+.

• Soils

  Medium-heavy, moderate-high fertility (eg. Olsen P is greater than 12, 0 to 10 centimetres). Tolerates slight salinity.

• Temperature

  Cold and frost tolerant, growth constrained by high temperature.

• Establishment
  Grassses and/or Cereals

  Perennial ryegrass.

  Legumes

  White clover, medics and sub clover.

  Sowing/Planting Rates In Mixtures

  10-18 kilograms per hectare.

  Sowing/Planting Rates as Single Species

  10 to 25 kilograms per hectare.

  Sowing Time

  Autumn and Spring.

  Inoculation

  P and possible N at sowing.

• Management
  Maintenance Fertiliser

  Requires fertile soil to persist. Approximately equal to 10 kilograms P per hectare. Monitor S, K, Cu especially. Supply N by clover/fertiliser. Maintain Colwell P approximately equal to 30 (WA), Olsen P is greater than 12.

  Grazing/Cutting

  Tolerates close, continuous grazing except if drought stressed. Graze at 2.5 to 3 leaf stage to optimise yield under rotational grazing. Well suited to hay/ silage.

  Ability to Spread

  Will spread if allowed to seed.

  Weed Potential

  Widely naturalised on fertile soils in temperate Australia.

  Major Pests

  Red and black-headed cockchafer, black field cricket, white-fringed weevil, African black beetle, corbies, underground grass caterpillar.

  Major Diseases

  Crown rust, stem rust, barley yellow dwarf virus, ryegrass mosaic virus.

  Herbicide Susceptibility

  In considering selective herbicides consider the stage of growth of the ryegrass and what non-target companion species are present.

• Animal Production
  Feeding Value

  High nutritive value.

  Palatability

  Palatable.

  Production Potential

  High yields; highly responsive to fertiliser and irrigation.

  Livestock Disorders/Toxicity

  Cultivars with wild endophyte can cause perennial ryegrass toxicosis and ill-thrift. Bacterial infection of seedhead can occasionally occur and result in ergot poisoning
