Timeline: 2015 -2019
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.
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.
