Choosing the right perennial ryegrass or combination of perennial ryegrasses is an important
decision to increase the production, persistence and quality of pasture harvested on your farm.
Perennial ryegrasses can be effectively classified according to endophyte strain, flowering time and
whether a tetraploid or diploid. Endophyte strain should be chosen relative to the known or
expected insect pests on your property. Using paddocks of ryegrasses with different flowering dates
on your farm will help to improve early and late spring growth and make it easier to sustain high
pasture quality and DM intakes throughout spring and into summer. Tetraploid ryegrasses offer
high quality feed, easy management and high utilisation but are particularly prone to pugging and
treading damage on wet soils in the early part of spring.http://www.side.org.nz/Paper
