Festulolium is an extremely vigorous, high yielding Meadow Fescue x Italian Ryegrass which is ideally suited for silage and pasture production from the Pacific Northwest to the Atlantic Northeast states. Festulolium has excellent forage quality due to its abundance of highly digestible, leafy tillers. It is a great choice for a fast-starting, high forage-quality grass for silage or pasture, either mixed with legumes or as a pure stand. Pure stand seeding rates are from 25 to 45 lbs per acre. Seeding rates in mixtures are from 8 to 20 lbs per acre. A seeding rate of 5 to 7 lbs per acre may be used as a companion crop for establishing alfalfa, reed canary grass, or other slower starting species to provide faster ground cover plus additional quality forage during the first year or two after seeding. Festuloliums are best adapted to soils with higher organic matter content and moisture levels. Their yields are responsive to nitrogen fertility rates.

Festulolium is a hybrid cross between the Festuca and Lolium species. The agronomic benefits of festulolium started to gain acceptance in the late 1950’s with demand steadily increasing over the years. Festulolium is mainly utilized in pastures for grazing and stockpiling, either in mixes or pure stands. Silage and green chop are other major uses. Benefits include higher forage yields than perennial ryegrass, forage quality similar to perennial ryegrass, increased mid summer growth compared to other cool season grasses, high disease resistance, winterhardiness and persistence.

Festulolium is a perennial bunchgrass which has the combined traits of the Festuca and Lolium species. The expression of these traits varies by variety. There are approximately 227,000 seeds per pound.

Festulolium is adapted to cool humid climates as well as less humid climates with supplemental irrigation. Festulolium does well on fertile soils with a pH of 5.5 to 7.0 but is not recommended for poorly drained soils or soils with poor fertility.

Festulolium is easy to establish due to its rapid germination and seedling vigor. Seeding rates are 25 to 45 pounds per acre if seeded alone and 8 to 20 pounds if used in mixtures. Seeding depth is 1/4 inch.

In general, 150 pounds of nitrogen per acre per year will be adequate to maintain a good stand of festulolium. The rule of thumb is to apply 1/3 of the nitrogen in the spring with the balance evenly applied after each harvest or grazing period.

Festulolium performs best under a rotational grazing system and should be grazed down to 3 to 4 inches when plants reach a height of 10 to 12 inches. For silage or green chop, festulolium needs to be cut before seed heads emerge for optimum forage quality.
