Smooth Brome (Bromus inermis Leyss.)

Description

Smooth bromegrass is a leafy, sod-forming perennial grass best suited for hay, silage, and early spring pasture, especially on well-drained soils. It spreads by underground rhizomes and through seed dispersal.

Strengths

High spring yield; winter hardy; sod-forming; leafy summer regrowth; good drought survival; best on fertile, well-drained soils.

Limitations

Difficult to drill unless mixed with something like oats; susceptible to damage when cut or grazed in jointing stage; not tolerant of frequent cutting; poor summer regrowth; susceptible to leaf diseases.
