Perennial Ryegrass

Lolium perenne

Perennial Ryegrass is the most widely grown cool season forage grass in the world. In the past, perennial ryegrass use in North America was limited because existing varieties were only adapted to regions with mild climates. In the last few years, Barenbrug has successfully introduced more productive and more persistent varieties into North America.

Perennial ryegrass is persistent if soil fertility is high. It also tolerates intensive grazing and cutting, re-growing quickly after defoliation. Since different varieties exhibit a wide range of characteristics such as maturity, winter-hardiness, disease resistance, digestibility, dry-matter production and persistency, perennial ryegrass fulfills the needs of many different farming systems. Careful management and variety selection ensure the best results.

Perennial ryegrass is ideal for making high quality grass silage, cut and carry and grazing. It can also be planted with alfalfa.

Barenbrug offers straight perennial ryegrass varieties as well as blends. The benefit of blends is their wider adaptability in different areas. In past years, these blends have proven their value to US farmers and ranchers.


BG-24T is a unique, innovative blend of early and intermediate maturing diploid and tetraploid perennial ryegrass varieties. Nearly a decade ago, Barenbrug released BG-34 a blend with late maturing perennial ryegrass varieties. Since then, Barenbrug breeders have selected new more heat and cold tolerant perennial ryegrass varieties at trial sites in USA.
Research by Barenbrug USA has shown that under high summer temperatures, early and intermediate maturing varieties perform better than very late maturing varieties. These new varieties have better disease tolerance and they perform better in the extreme environmental conditions experienced in cool-season grass growing regions of United States. BG-24T consists of mainly diploid perennial ryegrass varieties which provide a dense stand, along with some tetraploid perennial ryegrass which improve the overall palatability and productivity of the grass field.

  1. Clover often out-competes other plants in untzrfilieed lawns. It adds nitrogen to the soil, so is sometimes viewed as a desirable species in a low-maintenance mix. Regular fertilization (three times per year) will decrease clover, and the herbicide MCPP is a very effective chemical control for clover. MCPP is an ingredient in many herbicides available at garden centers.
