Diploid perennial ryegrass

  • Outstanding early spring growth 
  • Terrific fit for sheep and beef systems
  • Very high annual DM yield, similar to Trojan
  • Available with AR1 endophyte
  • Very early heading date (-7 days)

    Tyson is NZ's earliest heading (-7 days) perennial ryegrass, with tremendous early spring growth and excellent overall yield. This makes it an ideal fit for sheep and beef systems, where additional feed in early spring is critical through lambing and calving.

    Seasonal growth

    Tyson has excellent total DM yield, but it’s in early spring that it really shines with 18% more yield than other perennial ryegrasses.




    Sheep and beef system fit

    Tyson provides exceptional early spring growth, which can be very valuable, not least because it allows more lambs to be finished off mum. This has always been a key goal for sheep and beef farmers as:


    • Early lamb drafts usually fetch higher price schedules.
    • The weaning check is avoided (and with it up to 2 weeks lost lamb LWG).
    • Extra feed is freed up for other stock.


    Grow more when you can

    Tyson is particularly suited to dryland farm systems that need to maximise animal growth before the possible arrival of summer dry conditions.


    Managing Tyson to capture benefit

    While Tyson has the genetic potential to grow outstandingly in early spring, the second part to farmers capturing this advantage is the right management. Like any pasture it should be set stocked at a minimum cover of 1500 kg DM/ha (or 4 cm) through lambing. Otherwise it won’t have the leaves to capture enough sunlight to grow to its genetic potential, which is the science behind the saying ‘grass grows grass’.

    Description & heading dates


    Throughout NZ, perennial ryegrass (Lolium perenne) is the grass of choice for permanent pastures. It establishes rapidly, yields well, tolerates a range of management practices and has a high nutritive value.
