Sorghum-Sudangrass (SS) is a powerhouse for first-year biomass production, but the real risk can show up in the crop that follows. In fact, a broad meta-analysis by Zhang et al. in 2021 indicated that allelopathy can cause an average 25% reduction in the performance of a subsequent crop. For a sensitive crop like spring canola, that translates directly to a …
Finding The Sweet Spot: Sorghum-Sudangrass Seeding Rates (And What They Mean for Next Year’s Small-Seeded Crops)

It has become a favorite among Northern Ontario producers. To improve palatability, digestibility and yield, more growers have been pushing for higher seeding rates, without knowing that a quiet issue is creeping in. Crop emergence …
