The Benefits of Wider Row Spacing for Canola Seeding

As seeding technology has evolved so has row spacing. Where we used to plant using a six- or eight-inch spacing, we’ve moved up to 10 and 12 inches and now we’re seeing farmers using 15 inches. With the wider row spacing its providing benefits to the plant that no one thought we could have before.

The wider row spacing gives canola more space, increasing the rate of photosynthesis. It allows for more lignin to be produced in the plant — by generating more lignin it lessens lodging risk and makes for a healthier plant stand. This allows the crop canopy to close reducing disease incidence in fields, and therefore requiring for less herbicides and fungicides to be used. It’s really a snowball effect.

Another benefit is reduced seed costs. While overall you are planting less plants, the wider row spacing stops overcrowding in fields which can cause seed mortality. You’re letting the plant flourish instead of choking it out.

SeedMaster has been a leader for wider row spacing, while still continuing to offer seeding options for traditional row widths. I think that they are on the right track for anything new and upcoming in the ag world. They’re doing the right things at the right time for farmers.

Video: Sclerotinia and Lygus in Seed Canola: Field Update with George Lubberts, CCA | Enchant, Alberta

Join Certified Crop Advisor George Lubberts for this Prairie Certified Crop Advisor (Prairie CCA) field update from Enchant, Alberta. In this 12th video of the series, George takes us into a seed canola field where the male rows have been removed and the female plants are filling pods. This video was taken in the third week of August 2025.

George discusses the early signs of sclerotinia stem rot, explaining how infection begins in the stem, impacts pod development, and leads to premature ripening. He also shares insights on lygus bug management, including timing of spray applications to minimize feeding damage and maintain seed size and quality.

With cool, damp summer conditions, George notes that while disease pressure is present, overall field health remains good. The crop is just beginning to show early seed colour change, signaling progress toward maturity.

Topics Covered:

•Sclerotinia stem rot identification and impact

•Managing lygus bugs in seed canola

•Crop stage and seed colour change observations

•Timing insecticide sprays for optimal protection

•Insights from a CCA field perspective in southern Alberta
