Orchardgrass

Scientific name:Dactylis glomerata
Cultivars:Medium to late maturing: Haymate, Quickdraw
Late maturing: Echelon
Origin:Europe
Growth Habit:Bunch, 2-4 ft
Life Cycle:Perennial
 
Use
 
Production:Hay and pasture.
Early spring growth
Nutritive Value:
  • Relatively high protein (CP) and DM digestibility
  • less palatable than timothy grass
  •  
    Identification
     
    Seed Head:Panicle (2 to 8 in long), 3 to 5 florets/spikelet
    Seed:1/4 inch long, plumes attached
    Shoot:Flat stem at base. Light green (chalky)
    Leaf:broad (2 to 8 mm wide); v-shaped; bluish-green
    Auricles:None
    Ligule:Membranous, prominent with ragged edges, cut or splits
     
    Adaptation
     
    Soil:Sandy loam
    pH:5.8 to 7.0 but will grow up to 8.0
    Moisture:Fair drought tolerance
    Temperature:Fair winter hardiness
    Other:Will not grow well in waterlogged soils
     
    Establishment - Management
     
    Seeding rate:10 to 15 lb/acre (alone); 3-5 lb/acre (in mixtures)
    It's very aggressive not compatible with low growing legumes
    Easy to establish
    Seed cost:~$3 to 4.25/lb; ~$30-40/acre (alone); ~$10-20/acre (mixes)
    Planting date:Early spring (March thru April 15) to late summer (Aug. 15 to early Sep)
    Planting depth:1/4 to 1/2 in
    Frost seeding:Good
    Fertilization:Add lime, P, and K based on test results.
    When growing with legumes no N is needed.
    70 to 150 lb N/acre if growing grass only.
    Apply in split applications (early spring and summer).
    Grazing:
  • Graze frequently to maintain quality.
  • Leave 1 ft stubble height
  • Rapid recovery following grazing
  • Hay:
  • Matures rapidly. Use late-maturing species.
  • Regrows quickly after cutting
  •  
    Notes
  • N should not be applied in the fall because it will stimulate late fall growth (reducing winter hardiness)
  • Lacks winter hardiness
  • Well suited in mixtures with red clover and alfalfa
