PERENNIAL RYEGRASS

Sample Icon Secondary
Expo perennial ryegrass
  • Very high sugar (water soluble carbohydrate) levels
  • Strong, year-round dry matter production
  • Late flowering and low aftermath heading
  • Strong cool season growth
  • Very high tiller density

Farm Type
Farm Type
  • Sowing Rate 25 kg/ha
  • Heading Date Late - 21 days later than Nui
  • Tetraploid/Diploid Diploid
Expo diploid perennial ryegrass is a densely tillered, late flowering perennial ryegrass bred to deliver high quality feed throughout the year. Available with AR37 or AR1 endophyte, Expo perennial ryegrass can be utilised in both rotational and set-stocking grazing systems with soils that have medium to high soil fertility.

Dry Matter Production Comparison of Expo AR1 vs Aberdart AR1 (Expressed as a percentage of Aberdart AR1)

Entry Winter  Spring  Summer  Autumn  Total 
 Expo AR1 122  100  117  124  111 
 Aberdart AR1 100  100  100  100  100 

Data are the mean of three completed trials located in Waikato (1) and Canterbury (2).

Expo AR1 produced a significantly higer yield than Aberdart AR1 during establishment and in Winter and Autumn, but differences were not significant in spring, summer and total yield. 2006-2012.

Sowing & Establishment

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


  • Pasture Life 5 years+

Grazing Management

Expo perennial ryegrass is also suitable for long term hard grazing/set stocking in addition to rotational grazing.
  • Grazing Method Rotational Grazed – Long Term

Mix Suitability

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

Nick Browning has been using Expo for 5 years. Nick says “Expo is so dense it will fight well and keep the Kikuyu out. In a drought it stays green and bounces back quick after rain. The cows love it and after a few days grazing we notice a lift in their production.”
