Precision Planting Canola

Farming Smarter Project

Timeline: 2015 -2019

Study contact: Ken Coles

Abstract

Canola producers are increasingly adopting the use of precision planters to seed their crops, particularly in regions where they are already in use for corn and soybean.  Precision planters provide superior depth control and seed distribution than conventional seeders, and thus may improve the proportion, uniformity and rapidity of canola emergence. The primary purpose of this study is to assess the growth and yield differences between canola crops planted using an air seeder and canola crops planted using a precision seeder.

Objectives

1. Explore yield effects of seeding canola with a planter vs air seeder.
2. Assess how much and how consistently does a precision planting system improve canola emergence and uniformity.
3. Determine the optimum seeding rate with when using planter on 12” and 22” spacing.
4. Communicate the risks and rewards of seeding canola with planters on wide row spacing.
5. Determine maximum seed-safe rate of in-row liquid P when using a precision planter.

Methods

Location: Lethbridge (irrigated and rain fed sites), Medicine Hat (rain fed site)

Trial #1:  

Planters vs Air Seeders -3 X 5 Factorial RCBD

  • Seeding System (n=3):
    • precision planter 12 inch spacing
    • precision planter 22 inch spacing
    • conventional planter (air drill 9.5 inch spacing)
  • Seeding rate (n=5):
    • ultra-low (20 seeds/m2)
    • very low (40 seeds/m2)
    • low (60 seeds/m2),
    • medium (80 seeds/m2)
    • high (160 seeds/m2)
  • Total of 15 treatments, each replicated four times in a split-plot design to reduce the impact of spatial variability on treatments of most interest.

Trial #2:

Seed Placed Liquid Phosphorus 3 X 5 Factorial RCBD:

  • Seeding System (n=3):
    • precision planter 12 inch spacing
    • precision planter 22 inch spacing
    • conventional planter (air drill 9.5 inch spacing)
  • Seed placed liquid ammonia phosphate (10-34-0)
    • 0 kg/ha P205
    • 5 kg/ha P205
    • 10 kg/ha P205
    • 20 kg/ha P205
    • 40 kg/ha P205
    • 80 kg/ha P205

Total of 15 treatments, each replicated four times in a completely randomized block design

Plot Design: Factorial RCBD, 4 reps

 

12″ Spacing: 20, 40, 60, 80, 160 seeds/m2

 

Results

This project is ongoing. Results for this project will be provided when they become available.

Recommendations

We have one more season on this trial before we make recommendations.
