Marshall Annual Ryegrass

Productive Cool-Season Forage for Winter & Spring Grazing

Marshall Annual Ryegrass (Lolium multiflorum) is a productive cool-season annual forage grass widely used for winter and spring grazing, hay, overseeding, and supplemental livestock forage. Marshall is known for its strong forage production, good cold tolerance, palatability, and ability to produce high-quality feed during the cool season.

For livestock producers, Marshall can help fill the forage gap when warm-season pastures are dormant. It establishes quickly under favorable conditions and can provide dependable grazing from fall through spring when moisture and fertility are available.

  • Productive cool-season annual forage
  • Excellent livestock palatability
  • Strong winter and spring growth
  • Good cold tolerance
  • Fast establishment
  • High-quality grazing forage
  • Excellent cattle pasture
  • Useful for hay production
  • Responds strongly to nitrogen
  • Can be planted alone or in mixtures
  • Useful for overseeding warm-season pasture
  • Extends the grazing season

Extend Grazing Beyond the Warm Season

Marshall Annual Ryegrass is primarily grown to provide high-quality forage during the cooler months when bermudagrass and other warm-season pastures are dormant or producing very little growth.

Its ability to establish quickly and produce leafy forage makes it useful for:

  • Winter cattle pasture
  • Spring grazing
  • Stocker cattle
  • Cow-calf operations
  • Dairy forage
  • Sheep and goat pasture
  • Hay
  • Overseeding
  • Cool-season forage mixtures

Rather than relying entirely on stored hay through the cool season, producers can use annual ryegrass to add actively growing forage when conditions allow.

High-Quality Forage Livestock Want to Eat

Marshall Annual Ryegrass is highly palatable and can provide excellent nutritional value when maintained in a leafy, vegetative stage.

Grazing Benefits

  • Highly palatable
  • Leafy forage growth
  • Excellent cool-season grazing
  • Strong spring production
  • Good regrowth after grazing
  • Suitable for rotational grazing
  • Useful for cattle, sheep, and goats
  • Helps extend seasonal forage availability

Marshall can be particularly valuable for stocker cattle and other livestock classes where high-quality forage is important for performance.

Keep Forage Growing Through the Cool Season

Marshall is known for its ability to provide forage during the winter and spring grazing period.

Growth rate will depend heavily on temperature. Production slows during very cold periods but can increase rapidly when temperatures moderate.

Seasonal Growth Pattern

Fall: Establishment and early forage production

Winter: Continued growth during favorable temperatures

Early Spring: Rapid vegetative production

Late Spring: Heading and maturity as temperatures rise

This growth pattern makes Marshall useful for bridging the forage gap between dormant warm-season pasture and spring green-up.

Key Features

Strong Forage Production

Marshall can produce substantial amounts of cool-season forage when adequate fertility and moisture are available.

Excellent Palatability

Livestock readily consume young, leafy ryegrass, making Marshall an excellent grazing forage.

Good Cold Tolerance

Marshall is known for strong winter hardiness among annual ryegrass varieties, helping it persist through colder conditions.

Rapid Establishment

Annual ryegrass germinates and establishes relatively quickly under favorable fall conditions.

Excellent Spring Growth

Marshall produces vigorous growth as temperatures begin warming in late winter and spring.

Strong Regrowth

Properly managed stands can recover after grazing and provide multiple grazing cycles.

Flexible Use

Marshall can be planted alone, overseeded into existing pasture, or included in cool-season forage mixtures.

High-Quality Cool-Season Forage with the Right Management

Marshall can be useful in West Texas where producers have adequate fall establishment moisture, irrigation, or dependable seasonal rainfall.

Potential uses include:

  • Irrigated winter pasture
  • Stocker cattle grazing
  • Overseeded bermudagrass
  • Cool-season grazing mixtures
  • Spring forage production
  • Hay or greenchop
  • Supplemental livestock pasture

Because West Texas rainfall can be unpredictable, available soil moisture and irrigation capacity should be considered before planting large acreages.

Marshall can produce excellent forage, but it is not a low-water crop when the goal is maximum winter and spring production.

Add Cool-Season Production to Warm-Season Pasture

Annual ryegrass can be overseeded into established bermudagrass after warm-season growth begins slowing in the fall.

This allows producers to use the same acreage for:

  • Warm-season Bermuda production
  • Winter ryegrass grazing
  • Early spring forage

Overseeding Advantages

  • Extends pasture utilization
  • Adds high-quality winter forage
  • Reduces dependence on stored feed
  • Makes use of established pasture acreage
  • Provides strong spring grazing

Competition should be managed carefully in spring so late-growing ryegrass does not unnecessarily delay bermudagrass green-up.

Establish in Fall for Cool-Season Production

Marshall is generally planted in the fall so plants can establish before colder winter conditions arrive.

General Planting Information

Crop: Annual Ryegrass

Cultivar: Marshall

Scientific Name: Lolium multiflorum

Crop Type: Cool-season annual grass

Primary Uses: Grazing, hay, overseeding, forage mixtures

Planting Season: Fall

Establishment: Seeded

Sun Requirement: Full sun

Planting Method: Drill or broadcast

Planting Depth: Approximately ¼–½ inch

Growth Period: Fall through spring

Planting date should be adjusted to local temperatures, moisture availability, and intended grazing period.

Adjust the Rate for Planting Method

A practical general seeding range for Marshall Annual Ryegrass is:

Drilled

20–30 lb./acre

Broadcast

25–35 lb./acre

In Mixtures

Reduce the ryegrass rate according to the amount of wheat, triticale, oats, rye, clover, or other species included.

Higher rates may be appropriate where rapid ground coverage is especially important.

Final rates should account for:

  • Germination
  • Seed purity
  • Planting method
  • Seedbed condition
  • Overseeding vs. prepared seedbed
  • Mixture composition
  • Desired stand density

Good Seed-to-Soil Contact Improves Establishment

Marshall establishes best when seed has good contact with moist soil.

Establishment Tips

  • Control existing weeds
  • Prepare a firm seedbed
  • Avoid planting too deeply
  • Drill approximately ¼–½ inch
  • Firm broadcast seed into the soil
  • Plant when moisture is available
  • Irrigate after planting when necessary

When overseeding into existing pasture, reducing excessive residue can improve seed-to-soil contact.

Yes. Marshall produces highly palatable, high-quality forage and is an excellent option for cattle grazing.

Is Marshall Annual Ryegrass cold tolerant?

Yes. Marshall is particularly valued for its good winter hardiness compared with many annual ryegrass types.

When should Marshall Ryegrass be planted?

Marshall is generally planted during the fall. Exact timing depends on location, soil temperature, rainfall, and intended grazing date.

How much Marshall Ryegrass should I plant per acre?

A general rate is approximately 20–30 lb./acre drilled or 25–35 lb./acre broadcast. Rates should be adjusted for mixtures and planting conditions.

How deep should Marshall Ryegrass be planted?

Approximately ¼–½ inch is a practical planting depth.

Is Marshall Ryegrass a perennial?
