Northland
 

Northland Average

21% more drymatter

  • Northland showed the largest increase in drymatter production regionally with a 21% increase in drymatter production using ryegrass with AR37 compared to the same cultivar with standard endophyte. In comparison to AR1, it produced 15% more drymatter.
  • The impressive results ryegrass with AR37produced in Northland are primarily due to increased resistance to insect infestations common to Northland eg. black beetle.
  • The persistence of ryegrass with AR37 was also much stronger, producing more drymatter than standard endophyte and nil endophyte in the same cultivar, well into the pasture’s life.
 
Waikato & Bay of Plenty
 

Waikato & Bay of Plenty Average

15% more drymatter

  • Waikato and Bay of Plenty showed substantial improvement with a 15% increase in drymatter production using ryegrass with AR37 compared to the same cultivar with standard endophyte. In comparison to ryegrass with AR1 it had even better results, producing 22% more drymatter.
  • The Waikato and Bay of Plenty results from ryegrass with AR37 are primarily due to increased resistance to insect infestations common to the northern North Island eg. black beetle.
 
Manawatu
 

Manawatu Average

5% more drymatter

Manawatu is recognised as an area with lower pest pressure, but trials still showed an increase in drymatter production by 5% from using ryegrass with AR37 compared to the same cultivar with standard endophyte. In comparison to ryegrass with AR1, it had even better results producing 8% more drymatter.

 
Canterbury
 

Canterbury Average

8% more drymatter

  • Trials at Lincoln showed an 8% increase in drymatter production using ryegrass with AR37 compared to the same cultivar with standard endophyte.
  • This area has lower insect infestations than other regions, so this is still a considerable increase in drymatter production.

Agricom and PGG Wrightson Seeds products containing AR37 endophyte are supplied subject to terms and conditions of sale.

The trial results referred to are an average from trials held over three years by AgResearch Grasslands in Northland, Waikato/Bay of Plenty, Manawatu and Canterbury regions under which the performance of a ryegrass cultivar with AR37 endophyte was compared with the performance on the same ryegrass cultivar with standard endophyte. All trial regions showed an increase in drymatter from the cultivar with AR37 endophyte, with the range between regions being from a 5% increase to a 21% increase, and with average increase across the regions being 12%.

On-farm results will vary depending on many factors in addition to location.
