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 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

Corn growers often apply nitrogen later in the season to gain more control of the crop. At the V10 or V11 development stage, growers typically have a better understanding of how the crop is developing, its yield potential, the growing environment and what the market is willing to pay. There’s also logistics to consider —… Read More

Crop researchers can learn a lot in 28 years. That’s how long crop rotation trials have been on-going at the University of Guelph’s Ridgetown campus. On this episode of the RealAgriculture Corn School, host Bernard Tobin and University of Guelph crop researcher Dr. Dave Hooker look at the importance of crop rotation and key corn… Read More

As combines push through the Ontario corn crop, growers are being advised to focus their first harvest efforts on fields where gibberella fungus could produce higher levels of deoxynivalenol (DON) in the grain. On this episode of the RealAgriculture Corn School, agronomist Peter Johnson shares tips for identifying fields at higher risk for gibberella and… Read More

Good kernel set — from the tip to the butt of the ear — plays a key role in achieving high corn yield. But every year growers run into environmental and agronomic challenges the can lead to poor pollination, aborted kernels and a significant impact on yield. On this episode of the RealAgriculture Corn School,… Read More

Tar spot leaf disease has been a little tardy in 2023, but the later-arriving yield robber is still having an impact on the Ontario corn crop. Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta says a dry start to the growing year meant tar spot arrived a little late in 2023… Read More
