Perennial Ryegrass (Lolium perenne L.)

Perennial ryegrass is a bunchgrass with a relatively shallow, fibrous root system. It grows to a height of approximately 2’ (60 cm). Varieties are broadly split into two categories for the end user Turf type and forage type perennial ryegrass. The turf type varieties are bred for characteristics such as dark green colour, short growth habit and fine leaves. Most North American turf varieties also contain endophytes. Please consult our field staff for more details on endophytes. Forage type varieties are bred for feed characteristics, such as feed quality, hay yield, and palatability. This breeding generally leads to a taller plant with wider leaves. There is a strong, stable market for Perennial Ryegrass making it a favorable time for production.

Contract Quality The quality specs of the contract influence the field selection, in terms of weed issues. Some weed issues to consider are quack grass, wild oats, other course grasses, Canada thistle, catchfly and cleavers.

Seeding Seed companion crop at half the normal rate and reduce nitrogen levels. Cereals and flax work well as companion crops. When selecting a cereal variety, choose one that stands well and is early maturing. Cover crop lodging is a concern in getting a strong establishment.

Seeding depth up to ½ inch (1 cm)

Seeding rate 7 to 8 lb/acre (3 to 4 kg/acre)

Fertilizer 90 to 110 lbs N/acre (40 to 50 kgs/acre) Ensure nitrogen is available to the plant when it breaks dormancy in spring to achieve maximum yield potential.

Weed Control Consult our field staff for herbicide options.

Harvest The field is ready to swath in the last week of July or first week of August, roughly 25 days after flowering. The seed is ready for combining 6 to 10 days after swathing. The seed is safe for storage at 10 to 12% moisture. Resources such as moisture charts and combine settings are available.
