WCA research trial looks at managing drought risk by using split applications of N

Farmers taking part in this week's Cropportunities event learned what goes on behind the scenes in setting up a research trial with Wheatland Conservation Area (WCA).

WCA Farm Manager Bryan Nybo also talked about one of the research trials from last year looking at 'Managing Drought Risk Using Split Applications Of Nitrogen'.

Nybo says the trial was developed after producers who had been dealing with an ongoing drought, were asking if in a dry year, they could hold back on nitrogen at seeding time to save money, and then if it did rain later use a dual-band or post-emergent N to support higher yield potentials without being penalized.

He says they wanted to evaluate the results under dry and wet conditions and ran the trial at two different locations with Swift Current being the dry site, and Outlook running the same trial but under wet conditions.

"At Swift, we basically looked at can we save money by holding back nitrogen at seeding time? Our results showed very little yield response to increasing rates of nitrogen. We did show negative rates of return on fertilizer investment was the case in Swift Current. So we sure could save money. "

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
