Scientific name:Pennisetum americanum
Cultivars:Many.
Hercules, KF Prime 360, Wonderleaf, Tifleaf-1, Tifleaf-2, Tifleaf-3
Origin:West Africa (Maurituania to Sudan)
Growth Habit:
  • Erect;7 to 8 feet (forage types), 3 to 5 ft tall (grain types), similar to Sorghum
  • Life Cycle:Annual (warm season)
     
    Use
     
    Production:
  • Low yields, not competitive with corn or sorghum
  • 3000 to 4500 lb/acre
  • Used for pasture and hay, or grain.
  • Commonly used as late season emergency hay crop in upper midwest
  • Nutritive Value:
  • Excellent, comparable to corn
  • High CP (~45% higher than corn; especially under N fertilization), TDN in the 50% range
  • Lower in tannin than sorghum

    Identification
     
    Seed Head:Raceme (resembles 'cat tail'); Flowers July-September
    Seed:
  • Half the weight of sorghum seed (3-4mm)
  • Can be white, pale grey, pale blue, purple, yellow or brown.
  • Shoot:
  • 0.4 to 0.75" in diameter, round
  • Leaf:
  • Long, 5 to 40 inch long x 2.75 to 27 in (wide)
  • Vary from yellow green to purple
  • Auricles:Not present
    Ligule:Present, heavy ciliated (hairs)
     
    Adaptation
     
    Soil:Tolerates leached, sandy or low organic matter soils
    pH:> 5.5
    Moisture:Most drought tolerant of tropical cereal crops
    Temperature:
  • Soil Temps. of 65 to 70°F for germination
  • sensitive to frost
  • Other:
  • Use for grazing, hay or silage
  •  
    Establishment - Management
     
    Seeding rate:
  • 12-15lbs/acre drilled, 30-40lbs/acre broadcast
  • If grazing, use lighter seed rates. If cutting for hay, use heavier seed rates.
  • Seed cost:$1.5 to 2/lb; $24-30/acre (drilled), $60-80/acre (broadcast)
    Planting date:
  • Mid June to mid July
  • Planting depth:
  • 1/2 to 1 inch
  • Easy to establish
  • Frost seeding:No
    Fertilization:
  • Responds to fertility but no high nutrient demand
  • Typically limited by nitrogen
  • N needs 40 to 80 lb/acre
  • Excess N may result in lodging, best applied as manure.
  • P and K should be applied per soil test results. Drill row application may cause injury to seedlings.
  • Grazing:Plants should be allowed to grow 20"-24" before grazing, leaving 9"-12" of stubble for maintenance of stand.
    Hay:Plants should be cut at a height of 24"-36" for hay-overly mature plants beyond this height (past the boot stage) will not provide high quality hay.
     
    Notes
  • Does not have potential for prussic acid but can have high nitrate levels.
  • Grown for birdseed
  • European core borer
  • If grown for grain, store at 12-13% moisture
  • Recommended for horses and cattle
