Establishment and Management

Sowing

Arrotas clover is best established through full cultivation but can also be established by direct drilling into sprayed out pastures or oversowing onto well grazed sprayed out paddocks.

Cultivation

Paddocks that are to be cultivated out of pasture should be sprayed with the following:

  • Glyphosate + adjuvant in 100-150L/ha water
  • Pasture should be 5cm in length and actively growing. Spraying should occur in calm conditions.
  • This should be sprayed out 2 weeks prior to cultivation.

Cultivation

Cultivation should achieve a fine, clod and weed free seed bed with sufficient consolidation for the moisture conditions.

Sowing

Arrotas should be sown at 10kg/ha of inoculated seed, this can be drilled by roller drill followed by harrows and a roller, or conventionally drilled followed by a roller.

Direct drilling

Spraying

Paddocks that are to be direct drilled should be sprayed with the following:

  • Glyphosate + adjuvant in 100-150L/ha water
  • Pasture should be 5cm in length and actively growing. Spraying should occur in calm conditions.

Drilling/Grazing

Drilling/grazing should begin no sooner than 3 days after spraying. Arrotas should be sown at 10kg/ha of inoculated seed with slugbait.

Over sowing

  • Pastures to be oversown should be sprayed three weeks prior to sowing with a high rate of glyphosate + adjuvant and an applicable herbicide for wider weed control.
  • Grazing can occur 3 days after spraying, paddock should be grazed hard to open up ground to allow good seed to soil contact.
  • Arrotas should be oversown at 15kg/ha + slugbait and an applicable phosphate fertiliser.

Grazing

Grazing may occur when plants have developed a strong root system at about 6 – 10 weeks after emergence. Paddocks can be set stocked during late winter up to the first sign of flowering.

Stock may be reintroduced 6 to 8 weeks later once the seed is well developed, or this large bulk feed can be made into hay where mowing will knock seed onto the ground.

When paddocks are grazed by stock after flowering, it is said approximately 80% of the seed consumed by sheep will pass through the gut undamaged and is therefore capable of germinating next year.

As Arrotas has a very high hard seed percentage of 96%, the second year regeneration is very poor. An option for these paddocks is to sow an Italian ryegrass in autumn and graze through to the following autumn. Grass can then be sprayed out and Arrotas will germinate from the large seed bank grown in the first year.

Third year production will then be increased back to first year production levels. A self regenerating sward should now be seen for many years.
