VALLEY SEEDS Asteroid Tech Sheet

Asteroid is a unique Australian bred ryegrass variety designed to improve winter herbage yield and maintain long season production

  • Bred and grown in Australia
    Designed for local conditions with a unique cross of 50% annual and 50% Italian ryegrass, giving it the best characterises of the two species
  • Asteroid has the winter production of an annual with the later production of an Italian ryegrass
  • Selected for increased nutrient efficiency to allow better growth under lower soil fertility
  • It has the earliest heading date of the current Italian ryegrasses available on the market. This means it has excellent late winter/early spring growth before the season becomes too hot or dry in spring
  • The Italian ryegrass background improves its recovery after heavy grazing
  • Selected for faster emergence vigour to help with early sowing in unreliable autumn breaks
