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
How does strip tillage impact a corn plant’s ability to access and take up nutrients? On this episode of RealAgriculture’s Corn School, Ben Rosser, corn lead at Ontario Ministry of Agriculture, Food and Rural Affairs, looks at fertility research plots that compare how corn performs in both conventional tillage and spring strip tillage systems. In… Read More
When it comes to strip tilling, is it better to plant corn into fall strips or spring strips? Ben Rosser, corn lead with the Ontario Ministry of Agriculture, Food and Rural Affairs, has been working on this question for a while now, and in this Corn School episode, Bernard Tobin catches up with him in… Read More
What if corn, like soybeans, could fix its own nitrogen? It’s a question agronomist Dale Cowan and his team at AGRIS Co-operative are tackling this summer as they test a biological product that promises to help corn plants fix nitrogen, when applied directly on the seed, in pop-up fertilizer, and through foliar application between the… 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
Early planted corn is starting to emerge in Ontario and usually when digging around, a nice straight plant can be seen coming out of the ground. This year, though, a few plants are a little wonky. Down in Lambton County, Ont., agronomist Ryan Benjamins is seeing quite a bit of corkscrewing in corn this year,… Read More
The corn crop is in the ground in Ontario and it’s time to get out and scout. When scouting corn early in the season, diagnosis of issues is key for managing the crop further along in its growth. In this episode of Corn School, Bernard Tobin is joined in the field at Lambton County, Ont.,… Read More
There’s always plenty of attention paid to getting grain corn off to a great start, and the same principles apply when it comes to the finer points of planting corn for silage. With seed deliveries underway and planting season around the corner, Alana Serhan, market development agronomist for Pride Seeds in Western Canada, takes us… Read More
Precipitation, in both the frozen and liquid form, has been scarce in a large part of the northern corn growing areas of North America, creating the prospect of planting into a possible drought. There are several choices a grower can make to help maximize water use and mitigate drought risk, explains Alana Serhan, market development… 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
One of the keys to a high-yielding corn crop is even, uniform emergence. Growers can achieve this management goal in early-planted April crops when soil conditions are fit, but what happens when the weather turns bad and soil conditions take a turn for the worst at planting? On this episode of Corn School, Ken Currah,… 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
Sixty-inch spacing for corn is sure not for everyone, but the math and soil conservation rewards can work for farmers who have limited rotations and can benefit from extended grazing for livestock on well-established cover crops. That’s Sunderland, Ontario, farmer Ed Hanson’s takeaway from the first year of growing corn in 60-inch rows on his… Read More
Resistance to Bt corn rootworm hybrids has developed in Ontario and growers are asking: what’s the best strategy to control the yield-robbing pest if in-seed technology fails? Resistance has been confirmed in several fields in Huron, Perth and Durham Counties in Ontario and the problem is likely even more widespread, says Tracey Baute, Ontario Ministry… Read More
Selecting the right hybrids can make or break the profitability of a corn crop. There are a multitude of factors that combine to produce high-yielding, profitable harvests, but if growers make the wrong hybrid choices they’ll need some luck and good fortune to produce a successful crop, says University of Guelph associate professor Dr. David… Read More
