  • Low Bloat™

  • Goldstrike®

Strengths

  • Long growing season, extending into summer
  • Excellent spring/summer dry matter production
  • Responds well to summer rain
  • Ability to suppress summer weed species
  • Deep taproot
  • Highly palatable, bloat safe legume

Limitations

  • Intolerant of poorly drained or saline soils
  • Poor winter dry matter production

Plant Description
  • A self-regenerating temperate annual legume. Growth habit is erect to semi erect with a crown rosette of thick hollow stems reaching one metre in height.

  • Smooth, hairless.

  • Trifoliate, with leaflets up to 6 centimetres long and 3 centimetres wide, pointed at the tip. Leaflets have a distinct white V shaped marking.

  • Large up to 10 centimetres long and 3 centimetres across. White, developing a pink tinge as they mature.

  • Membranous, 2 to 3 seeded.

  • Reddish brown, ovoid, 1 to 1.2 millimetres, approximately 800,000 seed per kilogram. Arrowleaf clover has a high level of hard seed less than 80 per cent.

Pasture Type and Use

Arrowleaf clover is suitable for sheep/beef grazing or hay/silage production. It can be used in permanent pastures, short term pastures or in 1:1 pasture crop rotations. Provides valuable feed over late spring/summer for weaning lambs. Arrowleaf clover can extend the grazing phase beyond traditional sub clover pastures by 4 to 8 weeks.

Rainfall

Temperate regions receiving greater than 350 millimetres of annual rainfall. Requires adequate moisture from October to January to perform to its full potential.

Soils

Adapted to a range of soil types, moderate to high fertility, pH 5.0 to 7.5. Not suited to saline soils. Will not tolerate poorly drained, wet soils.

Temperature

Best adapted to a temperature range of 5 to 30°C. Tolerant of cold winter temperatures, but growth is suppressed.

Establishment
  • Compatible with all temperate grasses such as perennial ryegrass, cocksfoot, phalaris and tall fescue.

  • Sub clover, medics and serradella. Grazing herbs: Compatible with both chicory and plantain.

  • 2 to 3 kilograms per hectare. Ensure seed is Goldstrike® treated.

  • 6 to 10 kilograms per hectare. Ensure seed is Goldstrike® treated

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

  • New sowings will require fertiliser to promote early root development and enhance seedling vigour. Major nutrient requirements are phosphorous and potassium. Sulphur and molybdenum may be required in some areas. Soil test results and local knowledge of soil type and fertiliser history should determine rates to be applied.

Management
  • Arrowleaf clover is highly responsive to fertiliser, which should be applied regularly. For best performance maintain Olsen soil P level above 25.

  • Commence grazing when the plants are securely anchored. For newly established pastures plants should not be grazed once flowering has commenced so maximum seed set can be achieved. Must be grazed heavily when seed is mature to remove any residual dry material to ensure optimal regeneration in autumn. Plants are tolerant to heavy grazing over winter. Ideally suited to silage and haymaking. Growth in spring and early summer should be sufficient for two cuts of hay or silage.

  • Will regenerate from seed. When grazed by animals, in particular cattle, up to 30 per cent of the seed eaten will pass through the digestive tract and still remain viable.

  • Not regarded as an environmental weed. Can easily be controlled with selective herbicides in cropping areas

  • Susceptible to attack from red legged earth mites and lucerne flea particularly in the seedling stage. Bluegreen aphids have caused minor damage to crops in WA.

  • Susceptible to Phytophthora root rot under waterlogged conditions. Several viruses can affect Arrowleaf clover, the most serious Bean Yellow Mosaic Virus. Resistant to clover scorch.

  • Susceptible to herbicides or mixtures containing bromoxynil, terbutryn, diflufenican and 2,4-D amine. Will tolerate MCPA amine.

Animal Production
  • High quality forage with protein levels as high as 30 per cent measured. Feed nutritive value remains high through to maturity.

  • Highly palatable.

  • Production yields of over 10 tonne dry matter per hectare have been recorded in Tasmania and 9 tonne dry matter per hectare on the southern slopes of NSW.

  • No problems have been reported for stock eating Arrowleaf clover. Considered a “bloat safe” legume.
