Enterprises for this seed
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
  • Densely tufted, multi-tillered perennial with fibrous root system.

  • 30 to 90 centimetres.

  • 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.

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

  • 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 less than 12, 0 to 10 centimetres). Tolerates slight salinity.

Temperature

Cold and frost tolerant, growth constrained by high temperature.

Establishment
  • Perennial ryegrass.

  • White clover, medics and sub clover.

  • 5 to 10 kilograms per hectare.

  • 10 to 25 kilograms per hectare.

  • Autumn and Spring.

  • P and possibly N at sowing.

Management
  • 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 greater than 12.

  • 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.

  • Will spread if allowed to seed.

  • Widely naturalised on fertile soils in temperate Australia.

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

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

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

Animal Production
  • High nutritive value.

  • Palatable.

  • High yields; highly responsive to fertiliser and irrigation.

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