Sunflowers could help extend crop rotations and break disease cycle

Sunflowers is one crop that could hold a lot of potential for producers on the prairies. 

Currently, the majority of the acres in the prairies are found in southern Manitoba, with some acres also grown in Saskatchewan and Alberta.

Crops Extension Specialist Sherri Roberts says sunflowers is a crop that can be seeded a little bit later, and is generally harvested into October which can help to spread out the workload.

She notes there were producers in Manitoba that didn't get them seeded until the second week in June, and they still had a really nice growth pattern for the season.

Roberts says sunflowers can access water and nutrients at deeper depths than other plants.

"So some of these areas that have been really dry, they've got the nutrients sitting there in the soil, because the other crops haven't been able to utilize them. You put in a crop of sunflowers and I can guarantee you that they're going to go in they're going to scavenge that water that's there. They're going to scavenge nutrients, and they're going to come up with a really decent crop that's going to be a benefit to your bottom line."

Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Video: Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Can supplemental nitrogen help soybeans reach higher yield potential? Technical Agronomist Tim Sickman walks through an ongoing trial at the Nutrien Innovation Farm in Owensboro, Kentucky, exploring whether a modest amount of nitrogen applied at planting can support higher-yielding soybean environments.

The trial compares 30 pounds of supplemental nitrogen across both 15- and 30-inch rows, along with treatments that include sulfur and micronutrients. Similar trials conducted in 2024 and 2025 delivered a six- to seven-bushel yield response, prompting the team to expand the research this season.

Early observations show that treated soybeans are slightly taller and averaging about two additional nodes on the main stem. These added nodes could create more opportunities for blooms and pods, but the true results will come at harvest when the team evaluates pod development, seed fill and final yield.
