justification
Justification
  • Direct Seeding
  • One Pass Operation
  • Maximum N Rates in Seed Row

6-inch row = 10 lb 12-inch row = 5 lb

  • Mid-row Banding fertilizer
  • 14-inch Rows
  • Immobile Nutrient Uptake
materials and methods
Materials and Methods

Two Hybrids

    • Invigor 4870 (2005, 2006) or Invigor 5550 (2008)

- larger plant type

    • Hyola 357 Magnum - smaller plant type
  • Row Spacing
    • 7 inches
    • 14 inches
  • Seeding Rate
    • 7 live seeds / square foot
    • 14 live seeds / square foot
materials and methods11
Materials and Methods
  • Invigor 4870 planted in 14 inch rows
  • 8 live seeds / square foot
  • Two Sites (2005 and 2006)

  • Objective;
    • Evaluate the effectiveness of mid-row banding phosphorus fertilizer.
      • Collect plant tissue samples to determine when and how efficiently the plants utilize the phosphorus.
materials and methods25
Materials and Methods
  • Invigor 5550
    • 14 pure live seeds/ft2
  • 4 Sites
    • Langdon
    • Carrington – Low, Medium, Irrigated

Materials and Methods

Site Soil Test Yield Goal Applied

Low 5 ppm P2O5 2000 lb 17 lb P2O5

Medium 10 ppm P2O5 2000 lb 9 lb P2O5

Irrigated 9 ppm P2O5 4000 lb 22 lb P2O5

Langdon 9 ppm P2O5 17 lb P2O5

summary
Summary
  • Seeding Rate
    • 13% increase in seed yield as the seeding rate increased from 7 to 14 live seeds/ft2
  • Row Spacing
    • Smaller plant type (Hyola 357 Magnum)
      • Decreased yield as row spacing increased
        • 2 out of the 3 years
    • Larger plant type (Invigor 4870)
      • Yields were similar with 7 and 14 inch rows
summary32
Summary
  • Phosphorus Rate
    • Recommendations accurate
  • Phosphorus Placement
    • Minimal impact on yield
    • Injury with in-row application as rate increased
    • Reduction in plant growth with mid-row band application when the soil P levels were low
