Soybean School: Variety choice and population keys to lodging prevention

When soybean plants lodge, bad things happen.
Ontario Ministry of Agriculture, Food and Rural Affairs soybean specialist Horst Bohner says growers are okay with the "power lean" - that's when pod-laden plants tilt slightly under the weight of their bean bounty.
"But when they start to get close to the ground, and really lean over, you will often see more white mould in there and certainly other leaf diseases, even pod and stem blight and all those kinds of things." That's lodging and it typically adds up to disease, maturity delays and a yield penalty.
On this episode of the RealAgriculture Soybean School, we catch up with Bohner at OMAFRA's Elora research station where he's assessing lodging in soybean research plots. He says 2023 growing conditions, including a very wet, cool month of August, contributed to considerable plant growth and biomass accumulation. At the Elora site, soybean plots showed up to a 50 per cent increase in biomass, which contributed to a significant in increase in lodging, compared to 2022.
