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

The Christmas holidays are here! What better way to spend the time than catching some of the 30 Corn School episodes RealAgriculture published in 2022? We kicked off the season in January with Purdue University agronomy professor Dr. Tony Vyn who tackled the question: where does yield come from? Vyn notes that hybrid research over… Read More
How does adding 100 crop heat units to the maturity of your corn hybrids impact the yield and profitability of the crop? Agronomist Peter Johnson tackles that question on this episode of the RealAgriculture Corn School with help from University of Guelph associate professor David Hooker. Earlier this year, Hooker took a deep dive into… Read More
It appears in 2022 that Ontario growers have little to worry about when it comes to corn ear moulds such as gibberella contributing to elevated levels of mycotoxins in the corn crop. In late October, the annual Ontario corn ear mould and deoxynivalenol (DON) mycotoxin survey found 98 percent of samples tested low — less… Read More
Why are corn hybrids that typically reach eight and nine feet tall coming up as much as two feet short? It’s a question many Ontario growers are asking this year as the crop pushes through grain fill. On this episode of the RealAgriculture Corn School, PRIDE Seeds agronomist Matt Chapple digs into the “short corn”… Read More
Biostimulants designed to enhance performance and yield are nothing new in the corn management world. But growers can expect to see more and more of these products as manufacturers look to bring to market management solutions that alleviate the abiotic stresses plants experience when growing conditions are either too hot, cold, wet or dry. On… Read More
Corn growers often turn to tissue testing to diagnose a problem. When plants in a field are yellowing or pale, grabbing a sample and sending it to the lab can seem an obvious way to confirm a nutrient deficiency. But there’s more to the tissue testing story than simply identifying a problem and finding a… Read More
The practice of variable rate seeding for corn continues to increase as growers attempt to match seeding rates and hybrid characteristics to the varying yield potential across their fields. With the growth of precision agriculture, every year more growers adopt variable rate seeding strategies but are they effectively evaluating and fine-tuning this strategy on their… Read More
2021 was a big year for corn yield in Ontario. Although not official, the average yield is expected to check in at just over 200 bu/ac — a new record. On this episode of RealAgriculture’s Corn School, we take a closer look at where this yield is coming from with Purdue University agronomy professor Dr…. Read More
It’s November and Ontario corn growers continue to push through a harvest that will likely smash the provincial yield record. But there’s also lots of talk about the 2022 season, especially when it comes to fertilizer prices and what impact the cost of nutrients will have on growing corn when the calendar turns to next… Read More
A lack of late-season nitrogen and denitrification has been a concern this year, which is causing less than optimal growth in corn crops in parts of Ontario. Matt Chapple, market agronomist at PRIDE Seeds, has been getting plenty of calls this growing season about the issue, and in this Corn School episode, Bernard Tobin joins… Read More
The rain has come, and the corn crop is advancing fast. The crop is between tassel and silking stages, and the concern now is how to manage the crop for silage production. Will disease have an impact on the feed quality? Here to answer that is Albert Tenuta, OMAFRA plant pathologist, who joins Bernard Tobin… Read More
Weather is the ultimate source for small talk, and rainfall is perhaps the most talked about — from how much, to when, to not enough, and on too much. For this episode of the Corn School, Bernard Tobin asks Dale Cowan, senior agronomist at AGRIS C0-operative, about how much rain a corn crop needs throughout… Read More
With help from precision technology, corn growers are fully capable of conducting well-designed, logistically simple field trials that can help improve yield and profitability. When it comes to on-farm research, “that’s the beauty of today versus 30 or 40 years ago when I started in this business,” says Purdue University corn expert Bob Nielsen. On… Read More
What’s the secret to growing those gigantic corn yields that turn a select few U.S. farmers into corn yield contest kings? Purdue University corn guru Dr. Bob Nielsen has been pouring over National Corn Yield Contest data and crop input and management summaries from winners for almost two decades. What has he learned? After all… Read More
