Canola School: Seeding Speed & Seed Depth — What's the Impact?

Episodes:

Last week Kristen Phillips, Manitoba’s agronomy specialist with the Canola Council of Canada, introduced us to the Ultimate Canola Challenge set up near Portage la Prairie, Man., and offered tips on counting plant stands. The UCC, a demo of three teams all vying for top canola yields, includes three different canola varieties, seeding with two different implements, at different speeds but all on the same day.

In this episode of the Canola School, Phillips digs up a foot of row to not just count plants but instead to gauge the impact seeding speed has on seedling development, emergence and uniformity of the stand. Here we look at two plots: one seeded at 5 mph, the other at 3 mph. The range of seeding depth — and what that would mean in a less than ideal emergence period — is revealed in the video below.
