It’s been a tough spring for planting corn in Ontario. Planting season started in late April and some growers are now just getting their last acres in the ground during the final days of June. That seven-week planting season will present challenges for growers as they try to assess yield potential and apply fungicides to… Read More

As the calendar turns to the back half of June in Ontario, growers typically sharpen their focus on nitrogen management as the crop pushes into its rapid growth phases. But what’s happening in the field in mid June 2024 is really dependent on where in the province you farm and whether you’ve been able to… Read More
How do corn hybrids respond to foliar feeding? And what’s the potential yield impact and return on that investment? Those are questions PRIDE Seeds agronomist Stephanie Myslik tackles on this episode of RealAgriculture Corn School. In 2023, Myslik ran a trial to evaluate how tissue testing and foliar feeding could impact the PRIDE hybrid A6929G4…. Read More
Planting corn directly into a living cover crop before it is killed by herbicide or tillage is not something growers would have considered 30 years ago, says Ontario Ministry of Agriculture, Food and Rural affairs soil management specialist Jake Munroe. More and more farmers, however, are now willing to take the leap thanks to advances… Read More
What’s a planter supposed to do when it rolls into fields and tucks into a fit seedbed? On this episode of RealAgriculture Corn School, Kearney Planters operations manager Cullen Tinline shares a corn planter furrow management wish list and what growers should expect if their planter is fine-tuned, properly prepped, and rolling in good soil… Read More
There’s plenty of excitement for both economic and environmental reasons about the potential for biological nitrogen fixation for corn and other crops that don’t fix their own nitrogen, but a soil scientist from North Dakota State University says farmers and agronomists should be asking several key questions before counting on added organisms to supply N… Read More
There’s a long list of known ways in which wildfire smoke can negatively affect corn and other crops, but could the overall effect of the smoky haze in summer potentially be positive for yields? It’s a complex question to answer, says Dan Quinn, extension corn specialist with Purdue University, in this Corn School episode recorded… Read More
In recent years, many corn growers in Ontario have wrestled with gibberella ear rot in the crop and the high levels of deoxynivalenol (DON) levels it can produce in the grain. It’s made for stressful harvest seasons, especially in 2018 when mycotoxins produced by the gibberella fungus in some fields climbed well above safe feeding… Read More
Tar spot was a little late arriving in Ontario cornfields in 2023, but the leaf disease ramped up post tasseling, and with an extended fall, took a late-season bite out of grain yields in southwestern areas of the province. Growers who sprayed fungicides to defend their crop against disease were rewarded with higher yields, reports… Read More
Growers and agronomists typically focus on the ear leaf at flowering when tissue testing corn to determine nutrient needs. But is that still the best choice for determining the optimal nutrient prescription for the crop as it moves into the reproductive stages? Purdue University professor emeritus Dr. Tony Vyn believes the evolution of modern hybrids… Read More
