In 2022, the top 20 growers in the Great Lakes Yield Enhancement Network (YEN) harvested 50 bu/ac more wheat than the bottom 20 growers in overall yield rankings. What's really surprising, says RealAgriculture agronomist Peter Johnson, is that this gap exists despite there being only a five percent difference in yield potential between the two... Read More

Tar spot has been spreading across North American corn growing regions ever since the leaf disease was first detected in 2015. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen can deliver yield hits ranging from 20 to 60 bushels per acre (in highly infected fields). On this episode of... Read More

It's been 20 years since soybean aphids were first reported in Ontario soybean fields. Over the years, growers and researchers have learned that no two years seem to be the same and populations of the yield-robbing pests vary from year-to-year. There has, however, been significant changes to aphid behaviour over the years and this evolution... Read More

Winter is a great time to recalibrate your approach to managing wheat diseases and applying fungicides. That's the message Penn State University plant pathologist Alyssa Collins shared with agronomists attending the Ontario Certified Crop Advisors annual meeting earlier this month. It's a dormant period for humans and also for fungi and plants, says Collins. "So... Read More

Variety choice and planting dates are two key factors that drive soybean yield. On this episode of RealAgriculture's Soybean School, host Bernard Tobin asks whether later-maturing soy varieties are required for the highest yields and whether growers should plant soybeans before corn. For some answers, Tobin is joined by Michigan State University soybean educator Mike... Read More

Corn yields in Ontario have been increasing 2 bu/ac, or one per cent per, year over the past 40 years. Where is that yield increase coming from? University of Guelph associate professor David Hooker says genetics (65 per cent) and agronomy (35 per cent) are the key contributors to bigger corn crops. Corn breeders can... Read More
