Trifolium resupinatum sub species majus

Grazing and hay production

Late season persian with excellent recovery from grazing or harvest

Features
  • Excellent seedling establishment and winter growth
  • Very late maturing variety
  • Good frost tolerance
Benefits
  • Regrowth after grazing or harvesting is exceptional, growth rates comparable with companion grass species
  • Able to be sown early and continue to produce late in the season
  • Highly digestible source of forage

  • Goldstrike®

Strengths

  • High nutritive value
  • Extremely high production potential
  • Multi cut forage crop
  • Tolerant of seasonal flooding
  • Some tolerance of salinity
  • Free of oestrogen risks

Limitations

  • Poor regeneration

Plant Description
  • Erect, annual. Up to 750 millimetres height.

  • Up to 35 millimetres diameter, hollow, soft.

  • Trifoliate, up to 25 millimetres long, plain, strongly veined, oval-shaped leaflets with serrated margins.

  • Pink-violet flowers. Many-flowered cluster and mature in axillary, white, spherical, woolly seed heads to 15 millimetres diameter on long stalks.

  • Membranous, dehiscing at thickened sutures; one seeded.

  • Approximately equal to 1 millimetre long, ovoid, various colours (brown, olive, purple); Approximately equal to 1.5 million per kilogram.

Pasture Type and Use

A winter-growing, annual capable of excellent winter and spring growth. Suited to seasonal irrigation. A valuable fodder crop.

Rainfall

Greater than 500 millimetres in winter/spring rainfall zone for dryland use. Also used with irrigation. Tolerates water with up to 1500 siemens per centimetre on low salinity soils with adequate drainage.

Soils

Suited to clay soils, pH 5.5-8.5 (CaCl2). Tolerant of severe waterlogging and mildly saline soil.

Temperature

Good heat tolerance. Quite tolerant of frost and cold but slow growing at low temperatures

Establishment
  • Italian ryegrass.

  • Balansa clover, arrowleaf clover

  • 3 to 7 kilogram per hectare. Ensure seed is Goldstrike® treated.

  • 5 to15 kilograms per hectare; broadcast onto a finely worked, weed free seed bed and cover lightly by a roller or drill seed at 5 millimetre depth into a clean, finely worked seed bed. High seed rate boosts winter yield and reduces weed invasion. Ensure seed is Goldstrike® treated.

  • February (if irrigating) to April.

  • Goldstrike® treated. The use of Goldstrike® XLR8™ is recommended to reduce damage from insects at seedling stages.

  • Apply approximately equal to 20 to 30 kilograms per hectare annually and correct any nutrient deficiencies, especially K, Mo, Cu, S.

Management
  • For optimum growth Olsen soil P (0 to 10 centimetres depth) less than 15.

  • Suited to winter grazing. Set residues at 2 to 3 centimetres (winter) and 4 to 5 centimetres (spring) to avoid over grazing. Rotationally graze during the cool season when 15 to 20 centimetres tall; this stimulates tillering. If sown with grass must graze late winter/early spring to allow clover to contribute later. Suited to hay/silage production; most valuable aftermath. Stems are nutritious but slow to dry; use conditioner to speed up drying. Fast regrowth facilitates second cut; remove bales promptly, hay quite susceptible to rain damage

  • Red legged earth mite and lucerne flea need to be identified and controlled rapidly during establishment.

  • Some cultivars susceptible to leaf and stem rust (Uromyces trifolii-repentis) and clover rot (Sclerotinia trifoliorum).

  • Glyphosate. Damaged by many broad-leaf herbicides.

Animal Production
  • High (high soluble carbohydrate, high protein content and low NDF content). Retains excellent feeding value as dry standing hay during dry weather.

  • Highly palatable legume.

  • Good winter, spring, summer.

  • Low isoflavone content - no risk to breeding livestock. Low risk of bloat. Can be associated with photosensitization.
