Astound Tetraploid Annual Ryegrass

We recommend Astound Tetraploid Annual Ryegrass, which was developed specifically to fill the winter feed gap. It has excellent seedling vigour, establishes rapidly and is fast to first grazing, with high winter yields and quality. It suits all livestock types and areas with 450mm+ rainfall, on sandy to heavy soils.

For our Astound Tetraploid Annual Ryegrass, sow shallow at 10-15mm and roll afterwards to press the seed into good contact with the soil. Sowing deeper delays emergence and weakens seedlings. You can direct drill, sow into a cultivated seedbed or oversow an existing pasture, but control weeds before sowing in every case.

With Astound Tetraploid Annual Ryegrass, we recommend rotational grazing and letting plants regrow to the 2-3 leaf stage before grazing again. This lets plants rebuild energy reserves and gives the best balance of yield and quality. Astound also recovers well from heavy grazing, which helps it produce more total dry matter across the season.

Yes, Astound Tetraploid Annual Ryegrass can be oversown into an existing pasture as well as direct drilled or sown into a cultivated seedbed. Graze the old pasture hard first and control weeds so new seedlings aren't smothered. Sow at 25-35 kg/ha, keep drilled seed shallow at 10-15mm, and apply fertiliser at sowing.

Astound Tetraploid Annual Ryegrass is a dual-purpose option that performs consistently across the whole season, making it highly suitable for grazing, silage and hay. Its mid-late maturity gives reliable quality production into spring. Replace the nutrients removed by cutting with fertiliser so regrowth stays strong afterwards.

We suggest Astound Tetraploid Annual Ryegrass, which is tolerant of waterlogging and suits soil types from sandy to heavy. It needs 450mm+ rainfall and a soil pH of around 5.0 or higher. Its fast emergence vigour also helps where the autumn break is unreliable, getting plants established before the wettest part of winter.

We often pair Astound Tetraploid Annual Ryegrass with a sub clover suited to your rainfall, such as Seaton Park Subterranean Clover, or with Paradana Balansa Clover on waterlogged ground. The clover adds nitrogen and protein, while Astound supplies the winter bulk. Apply fertiliser at sowing to support both species, and graze lightly at first so the clover seedlings can establish.

Astound Tetraploid Annual Ryegrass is suitable for all livestock types, but like any annual ryegrass that is not ARGT resistant, it can carry annual ryegrass toxicity risk once seed heads form in affected districts. Where ARGT is a known problem, consider our Safeguard Diploid Annual Ryegrass. Introduce hungry stock gradually and graze rotationally.

Astound Tetraploid Annual Ryegrass is an annual, so it grows for one season and should be resown each autumn. It offers excellent winter and early spring production, high winter yields and mid-late heading. If you need a pasture that persists, talk to us about our perennial ryegrasses, such as Dunstan Perennial Ryegrass or Hypa Hybrid Ryegrass, in suitable rainfall zones.

It depends on how long your season runs. Both are tetraploid annual ryegrasses with strong winter growth. Astound Tetraploid Annual Ryegrass heads mid-late, so it holds production and quality further into spring and is highly suitable for silage and hay. New Tetila Tetraploid Annual Ryegrass heads early and is a reliable specialist winter crop with good yields into early spring.
