Annual Ryegrass

  • Diploid annual ryegrass
  • Good seedling vigour
  • Excellent early forage production
  • Ideal for winter grazing, silage and early hay production
  • Will fit into systems where it can be followed by a summer crop
  • Significantly improved winter production over Tetila
  • Upright and erect growth habit


    GrassMax™ is a diploid annual ryegrass that offers exceptional winter production. GrassMax™ provides a reduced cost feed option for low rainfall or short growing season regions or where fast winter feed and silage can be followed by a summer forage crop.



    Sowing Rate

    15-25 kg/ha (Pure) 10-15kg/ha (Mixes) GrassMax™ is ideally suited to sowing with competitive annual plants Eg. Zulu II Arrowleaf clover, Laser Persian Clover, Bolta Balansa Clover or Leafmore Forage Brassica.

    Key Benefits

    • Fast establishment leading to very short time to first grazing
    • High winter production levels allows for the winter feed gap to be filled
    • Was selected for its speed to first grazing and the resulting rebound from grazing
    • Offers very good adaptability to a wide range of soil types and climatic conditions
    • Densely tillered, fine leafed hardy option for range of environments


    Early to mid season maturity (similar to Tetila). An adaptable variety which grows on a wide range of soils.


    GrassMax™ is an exceptional performer where early vigour, quick winter grazing and early weed competition are required.  It is suited to to sheep/beef/cropping and dairy zones where time to first grazing is essential and pressure needs to be taken off other feeds.  


    Pest & Disease Resistance/Tolerance

    GrassMax™ has standard ryegrass disease resistance. as well as standard ryegrass pest resistance. Monitor for insect damage and control where necessary.


    Variety Management/Agronomy

    GrassMax™ is highly adaptable, but is best suited to ryegrass best management.  Rotational grazing, higher fertility and use of companion legumes will lead to better results. 


    Establishment- It is recommended to sow in autumn or spring into a moist, fine seed bed free of broadleaf weeds and other grasses and at a depth of 1-2cm. Can also be direct drill into bare ground or over sown into excising run–down pasture using the correct sowing equipment.


    Fertilizer- Establishment - depending on soil fertility apply 10-15kg/ha of nitrogen and a good amount of phosphorus. Maintenance - Topdressing with 40 -50kg/ha of Nitrogen after each grazing or cut. Correct trace element deficiencies as required based on soil and plant tissue tests.


    Grazing-For new sown pastures avoid grazing while plants may be pulled out or paddock is susceptible to pugging. Once established, rotational graze with grazing intervals of 21 -30 days between grazing, depending on climatic conditions.


    Weed Control- Appropriate weed control strategies should be used. For best results select a paddock that has just been in crop with a finely worked seedbed. Spray graze techniques using MCPA and Trifolamine, provide opportunities for good broadleaf weed control. Also selective herbicides for both broadleaf are available and useful for more effective weed control.

    Annual Ryegrass

    Sow for high quality short-term winter crops, to providing multiple grazings in winter & spring. It exhibits the greatest winter growth potential of all the ryegrass types. Generally used for a 6-9 month winter crop or to make the most of a growing season where late season rain is unreliable.
