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.

What insect threats are Minnesota corn growers facing, and what research is helping farmers stay ahead of them?

At the 2026 MN Ag Expo, University of Minnesota entomologist Fei Yang shared updates on three Minnesota Corn-supported research projects focused on insect monitoring, seed treatments, and pest resistance.

Current work includes statewide monitoring programs that use pheromone, light, and sticky traps to track key pests such as black cutworm, true armyworm, corn earworm, European corn borer, and corn rootworm. Researchers are also evaluating whether high-rate seed treatments provide effective corn rootworm control and studying the development of resistance in European corn borer populations to Bt corn traits.

These projects help researchers better understand pest pressures across Minnesota and provide farmers with practical information to support informed management decisions.
