Excess perennial ryegrass is a medium leaved diploid perennial ryegrass bred for very high dry matter production and cool season growth. Excess is ideally suited for maximising dairy production with high dry matter during summer and autumn while equally providing a quality option for intensive sheep and beef properties.

Excess AR37 116 107 128 120 115
Extreme AR37 100 100 100 100 100
*Data is the mean from five trials sown at LINCOLN, Canterbury (3) and Puturau, Waikato (2) 2008 to 2012. Trials ran for three years.

Heading date

Early Mid-Season Late Very Late
  Excess: 7 days later than Nui    

Sowing & 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 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).

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".
