Perennial ryegrass

  • Excellent dry matter production
  • Strong persistence (AR37)
  • Mid-season heading (7 days later than Nui)
  • Exceptional summer, autumn and winter growth
  • Low aftermath seed head emergence
  • Proven performance in upper North Island National Forage Variety Trials

  • Sowing Rate 25 kg/ha
  • Growing Seasons Autumn, Summer, Winter
  • Heading Date Mid-Season - 7 days later than Nui
  • Tetraploid/Diploid Diploid

Excess is a medium leaved, diploid perennial ryegrass bred specifically for tougher environments. It produces exceptionally high dry matter yields and the mid-season heading date provides an earlier flush of spring growth which makes it ideal for lambing and calving.

Excess is a tried and tested perennial ryegrass offering excellent production in more challenging soil types. Recent independent National Forage Variety Trial results demonstrate the productivity advantages Excess AR37 provides in the challenging Upper North Island environment.

  Excess: 7 days later than Nui    


Sowing and Establishment

Excess perennial ryegrass can be sown at 15-25 kg/ha with Superstrike® treated clover.

  • Soil Fertility High (Olsen P 18+)
  • Pasture Life 5 years+

Grazing Management

Excess perennial ryegrass will produce and persist better under rotational grazing. Avoid hard set stocking during periods of stress (e.g. droughts, low soil fertility and insect attack).

  • Grazing Method Rotational Grazed – Long Term

Mix Suitability

Excess perennial ryegrass combines well with other components of a pasture mix (e.g. short rotation ryegrass, cocksfoot and Grasslands Puna II chicory and clover).

Example pasture mixes

Dairy Pasture Mix
Excess perennial ryegrass 21 kg/ha
Legacy white clover 2 kg/ha
Quartz white clover 2 kg/ha

Sheep and Beef Pasture Mix
Excess perennial ryegrass 21 kg/ha
Quartz white clover 2 kg/ha
Hilltop white clover 2 kg/ha

For increased animal performance, nitrogen fixation and pasture management, add Amigain red clover to pasture mixes at 4-6 kg/ha.
Excess Perennial Ryegrass

Howard farms an intensive 60 ha dairy farm in the heart of the Waikato. Howard says Excess has been a revolution to his pasture management plan. "I have been growing Excess for three years now and it is definitely a 'game changer'. The biggest attribute that Excess has offered is the speed of feed and recovery after a dry spell".
