Annual Ryegrass is planted for as a stand alone pasture grasses or is overseeded into warm season pasture or grasses for winter forage. Annual ryegrass can also be planted in the Spring in the Northern areas of the USA.
While Oregon Grown and Gulf Annual Ryegrass are discussed here there are other varieties to choose from -- see our menu here on the right for additional information.
Oregon-Grown Annual/Gulf Annual Ryegrass.
Oregon-grown Ryegrass is highly preferred by livestock. Either
Oregon-grown common Annual Ryegrass or Gulf Annual Ryegrass will
provide livestock and other grazing animals with an additional six to eight months of
abundant, nutritious pasture which will see a young cow continue
to grow and gain while nursing a calf which is also gaining and
thrifty. Annual Ryegrass seed may be sown alone or in combination with
legumes or small grains.
For decades the annual ryegrasses have
demonstrated the ability to produce high quality forage which will
not go dormant or off color through the chill of winter and remain
productive on into the spring.
Annual Ryegrass Seeding Rate
Seed planting rate for Annual Ryegrass is 25-40 lbs. per acre. Overseeding will require less seed -- generally 15 lbs per acre. Harrow or aerate for best results to make good seed /
Ryegrass germinates in a
matter of 7-10 days or less in ideal conditions. Sowing dates
vary according to area. Some growers prefer to winter-seed pastures
after the first killing frost as a means of eliminating
competition from native grasses. Others prefer to sow earlier to
give the ryegrass seedlings an opportunity to flourish while the
ground is still warm.
First grazing of Ryegrass pastures is possible within about 90 days after planting.
While soil fertility and weather conditions
are determining factors, light grazing is often available in about
90 days after sowing. Some operators feel light grazing can
begin when the new grass is 4-5 inches high, while others wait for
greater growth so that the new plants will not be uprooted by
Because ryegrass quickly develops a
strong root system it helps prevent bogging in moist areas and
stabilizes precious topsoil.
Recommended rates of nitrogen
application and other fertilizers vary according to soil
conditions and the region but, in general, applications of up to
150 pounds per acre at or before planting are desirable. A
second application may be needed in mid-winter. Remember that the amount of nitrogen may be reduced or eliminated entirely with the companion planting of legumes such as clover.
