    Identification
     
    Seed Head:Panicle; it takes 28-30 days from heading to maturing
    Seed:
  • 32 lb/bushel
  • Kernels may be white, yellow, gray, red or black
  • Shoot:
  • 15 to 70 in; hollow
  • A single seed usually produces 3-7 stems
  • Leaf:Flat; 0.5-1.5 inch wide; 3-18 inch long
    Auricles:Absent
    Ligule:Present, medium length
     
    Adaptation
     
    Soil:Well drained
    pH:6-7
    Moisture:Requires more moisture than other cereals.
    Temperature:
  • Withstand 25°F without damage
  • Cool weather is important for high yield (grain filling and ripening)
  • Least cold tolerant of the small grains
  • Other:
  • For companion crops use earlier maturing, stiff-straw, short cultivars
  •  
    Establishment - Management
     
    Seeding rate:90-120 lb/acre (oat only); 45-60 lb/acre (mixed)
    Seed cost:$1.1/lb; $55/50 lb; $100/acre
    Planting date:Spring (reaching maturity 90-120 days after germination)
    Planting depth:1 1/2 inch
    Frost seeding:Yes, ideal conditions are when snow is gone, the soil is not frozen and the night temperatures drop to 28°F to 19°F.
    Fertilization:
  • Oats do better on less fertile soils than other small grains. Commercial fertilizer use may be profitable
  • 15-to-40 lb N/acre is recommended depending on previous crop.
  • 60 lb N/acre can be used for hay or pasture
  • Manure is recommend
  • Grazing:
  • Clipping or grazing is done in the vegetative stage and terminated before stem elongation. If the floral stem is removed the plants lose the ability to produce grain.
  • Hay:
  • Most spring oats are harvested in the month of July. When harvested for grain, moisture content should be 13-14%, which happens a week after they are 'ripe' or mature.
  • The ideal harvest stage for oats is mid-to late boot
  •  
    Notes
  • WI ranks 3rd in the country in oat production after ND and SD
  • Diseases include smut (Ustilago spp.) crown rust (Puccinia spp.), Septoria blight and leaf blotch
  • Insects pest are cereal leaf beetle, army worms
