    Establishment - Management
     
    Seeding rate:
  • 16 lb/acre (alone); 3-6 lb/acre (mixture)
  • Seed needs to be stirred.
  • Seed tends to bridge in drill. Seed with oats (spring only, using small grain box)
  • Seed cost:
  • ~$150/50 lb
  • Planting date:
  • Spring and late summer seeding by mid August
  • Produciton likely in the 2nd year).
  • Planting depth:1/4 to 1/2 inch
    Frost seeding:Difficult
    Fertilization:Responds to N. Mid to late summer applications will increase production
    Grazing:
  • Graze at 10 inches or when basal tillers are visible.
  • Stubble height: 4 inches.
  • Needs long recovery periods
  • Should not be grazed from early September thru mid-October to allow reserve accumulation
  • Light grazing after no-graze period.
  • Hay:
  • Cut first crop before late bud or early heading; cutting late may cause bromegrass to become semidormant and unproductive
  • Harvest legume/brome mixtures before brome stems elongate or after basal tillers are evident.
  • Spring harvest before jo

    Notes
  • Does not tolerate short stubble
  • Low seedling vigor, slow emergence
  • Use varieties resistant to phytium
  • Mixture with legumes are used widely for silage
