Annual Ryegrass

Annual (Westerwold) ryegrass is mainly used for annual hay or grazing applications but is also good for quick ground cover in some turf mixtures. Annual ryegrass is seeded in early spring and harvested mid-summer with similar management practices as wheat. It tolerates and thrives in excess moisture and is a great fit for mixed farms, as its straw can be used for feed and bedding, and its regrowth provides excellent fall grazing opportunities.

Field Selection

Annual ryegrass grows well in most Western Canadian regions and is well-adapted to different soil types, growing in everything from light-textured sandy soils to heavy clay soils. The field must be free of residual herbicides such as Edge® and Treflan®, and it’s important to review the herbicide history of the field before planting. Clean fields are important for minimizing weeds at harvest and earning top prices for your crop. Glyphosate application in the fall prior to establishment will help eliminate perennial weeds.

Weed and Disease Control

Markets demand seed free of wild oats, quackgrass and volunteer canola. There are good herbicide options for the control of broadleaf weeds, but options for in-crop
control of grasses are minimal. The selection of clean fields is important to maximize seed quality. Annual ryegrass is not susceptible to common fungal diseases, so fungicides are not required.

Seeding

Conventional seeding equipment can be used. Seeded at 15-18 lbs/acre, air drills, air seeders and hoe drills work well.

Harvesting

Annual ryegrass must be swathed. The number of days to reach full maturity is similar to barley. Annual ryegrass is usually harvested seven to ten days after cutting using either conventional or rotary combines. Annual ryegrass is considered dry at 12% moisture but can be harvested at 14% so long as aeration is used to cool the seed and remove excess moisture. Don’t use heat as it can affect germination.

Production Benefits

  • Large root mass improves soil tilth and water
    infiltration while helping manage soil erosion
  • Straw residue can be used for feed and bedding
  • Regrowth provides high-quality fall grazing
    with excellent feed value and palatability
