Corn School: A Fresh Look at Interseeding Cover Crops in Corn

Everything old is new again. That’s certainly the case when it comes to interseeding cover crops into corn. In this episode of Real Agriculture’s Corn School, University of Guelph-Ridgetown College researcher David Hooker unearths some historic evidence of Ontario farmers’ and researchers’ fascination with cover crops and their efforts to interseed them in growing cornfields….

Corn School: Picket Fence vs. Carbon Copy — Which is the Ideal Crop?

It’s a great problem to have, but gains of an average four to five bushels per acre per year is possible with today’s corn crop if modern genetics are managed properly. Of course, “managed properly” is too general — if Ontario’s average corn yield per acre is set to surpass the 200 bushel mark in… Read more »

Agronomy Geeks Ontario — Ep. 17: The Yield Impact of Wet Feet

There’s no two ways about it — huge swaths of Ontario’s growing region is now excessively wet. And not, “Hey, that was a heavy rainstorm!” wet, but soaked-right-through-for-the-third-time wet. With all this water, farmers are understandably nervous about what impact wet soil and standing water may have on the yield of the corn and soybean… Read more »

Corn School: How Much N Do You Already Have?

What’s the number one question you ask of yourself or your agronomist as you plan your corn crop? It’s likely, “What’s the right rate of nitrogen for this field?” It’s the golden question, as Dr. Dave Hooker, of the University of Guelph-Ridgetown, says, and the answer can be as low as zero or as high… Read more »

Corn School: How Hybrids Respond — Finding Synergies In the Field

Do you manage your corn crop differently, based on whether or not you’ll be using a fungicide or topped-up nitrogen rates? That may end up being a new recommendation, as research is beginning to offer clues on how each input works with the other — sometimes providing not just additive benefits, but synergistic ones (think:… Read more »

Corn School: What Does a “Day” Really Mean in Regards to Corn?

When a growing season doesn’t go exactly as hoped — a late spring, a cool summer, too much rain — corn growers get understandably nervous. Corn is a C4 plant — it can tolerate hot weather and needs rather warm weather to grow, set yield and mature. As much of Ontario deals with “weird and whacky”… Read more »

Soybean School: Go Big or Go Home — Does Intesifying Inputs Pay?

If you’re decided on rates and types of inputs, which do you skip or scale back on if margins become tight? Fungicide? Seed? Fertilizer? Should you cut back at all? The concept of intensively managing corn is widely accepted and researched, but not so with soybeans, so Dr. Dave Hooker and colleagues set out to… Read more »

Wheat School: Calculating the True Value of Each Crop in Rotation

When the time comes to put pen to paper (or fingers to keyboard) and look at the hard numbers behind the corn, soybeans and wheat in your rotation, it’s important to give each crop the credit it deserves. The truth is that when you run that rotation, unless you’re digging deep, wheat probably isn’t getting… Read more »

No Fungicides on Corn Just Before Tasseling!

The application of fungicides to corn between V12 and tasseling (VT) is not recommended. This recommendation is based on the potential for arrested development of corn ears, or the formation of “beer can” ear syndrome. The syndrome was termed by Dr. Bob Nielsen of Purdue University in 1996, who described the ears with the expected… Read more »
