Seeding

Canola Target Plant Populations

Stand Establishment and Survivability

  • Establishment: seed is able to germinate, emerge, and grow
     - Establishment % =  (Number of plants per square foot)
                                    (Number of seeds planted per square foot)
  • ​Survivability: the number of plants that contribute to yield
     - Survivability % = (Plant count after harvest)
                                 (Plant count at 4 leaf)
     - Also depends on pests, soil conditions, equipment, environment

PROBLEMS SEEDING ABOVE THE OPTINUM RATE

  5-7 PLANTS/FT2 OPTIMAL TARGET PLANT PRODUCTION

  


THE ADVANTAGES OF TARGETED PLANT POPULATION

  • Good Weed Control
  • Efficient use of resources
  • ​Even maturity with uniform plant structure
  • Reduced Intra-competition
  • Reduced Sclerotinia incidence
  • Reduced Lodging

     

SEEDING CONDITIONS

  • Too shallow or too deep reduces emergence rates 
      - Verify your drill is level and the openers are well maintained.
  • Seed into moisture 
      - One Inch
  • Packing Pressure
    ​   - Wet Conditions: reduce pressure 
       - Dry conditions; increase pressure

SEED DEPTH 

From left to right depth: .75", 1.25", 1.75"
All plots 233p at 78 seeds/m2

 Seed Depth & Consistency


Economic Opportunity for Improved Survivability

CANOLA TARGET PLANT POPULATIONS 
  • Target 5-7 plants/ft2 (10 seeds/ft2) 
     - What's your survivability? (plant counts)
     - What's your seed weight (TSW or TKW)
  • Seed into moisture
     - 1 - 1 1/4" has shown to be most consistent
  • Is your equipment set properly?
     - Check seed depth and seeds per foot
