Corn School: Fine tuning the combine to reduce DON levels

How can growers adjust their combines to reduce vomitoxin levels when harvesting the 2018 crop? RealAgriculture agronomist Peter Johnson has some answers. In this episode of Real Agriculture’s Corn School, Johnson visits with custom combine operator David Killins, of Killins Custom work, at Dorchester, Ontario. Johnson acknowledges that while cleaning corn does help, it’s not… Read more »

Corn School: Managing vomitoxin in the field and the silo

Agronomist Peter Johnson has been visiting cornfields and elevators to get a handle on the extent of vomitoxin levels in the Ontario corn crop. In this episode of RealAgriculture’s Corn School, Johnson discusses Ontario’s recent Grain Corn Ear Mould and Vomitoxin (DON) Survey, and notes that some samples coming off the combine have tested as… Read more »

Corn School: Plant deeper for higher yields

It might seem counter-intuitive, but slowing down corn emergence may actually boost yields. Plot results are in, and it would seem that optimum distance between corn plants matters far less than uniform emergence. And achieving perfectly uniform emergence takes planting deep. We already know that even emergence is key to top yields, but the mechanism… Read more »

Corn School: Harvest quickly to limit losses to gibberella

If you’re noticing a little fuzzy trouble with your corn crop this year — you’re not alone. With rainfall after rainfall at pollination (but not before!), the weather created perfect conditions for gibberella infection and spread. If you’ve scouted your corn crop and have found pink mould growth at the tip of the cob, chances are… Read more »

Corn School: Will wet weather bring late-season disease?

Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta is gearing up for his annual pre-harvest corn disease survey, and he’s optimistic leaf disease will not have a significant impact on the 2018 corn crop. Some growers have raised concerns that a rainy late July and August could lead to a flood… Read more »

Corn School: Will double-cob corn deliver bonus yield?

If you’re seeing double in your corn crop this year, you’re not seeing things. Double-cob stalks are showing up in many fields this season and farmers want to know — will these bonus cobs amount to anything, and why are they even there? Those are two questions Steph Kowalski, agronomy lead for the Agromart Group,… Read more »

Corn School: Fungicide application timing on a variable corn crop

Ontario corn growers will have plenty of variables to consider as they plan fungicide applications in the weeks ahead. An extended five-week planting season has produced huge variability in the crop, with current maturity ranging from the two- to eight-leaf stage depending on where you farm in the province. In this episode of RealAgriculture’s Corn… Read more »

Corn School: How Ontario stacks up in the corn production world

Is corn growing greener beyond Ontario borders? How does corn profitability and cost of production in the province stack up with other growing regions around the world — from the U.S. to South America, Ukraine, and China? These are some of the questions Ontario Ministry of Agriculture, Food and Rural Affairs business analysis and cost… Read more »

Corn School: Doing the math on multi-hybrid variable rate planting

Many Ontario corn fields have high levels of variability; soil profiles can change from sand to highly productive loam in a matter of footsteps. One way to tackle this variability is to identify management zones in the field and plant multiple hybrids at variable rates. In this episode of RealAgriculture Corn School, we catch up… Read more »

Corn School: How much corn residue should you remove?

Do your corn fields yield less than 170 bu/ac? If so, you have to be careful when removing corn residue from those fields because you could be depleting the field’s soil organic matter. That was the message USDA research agronomist Shannon Osbourne shared with those attending the recent Southwest Agricultural Conference at the University of… Read more »

Corn School: Understanding 30 years of rising yields

Ontario will set a new corn yield record in 2017 with the crop expected to hit an average of 180 bu/ac or better. Where is all that yield coming from? Corn physiologist Dr. Thijs Tollenaar has poured over the data and identified three key factors driving corn yield improvement. A long-time University of Guelph professor… Read more »

Corn School: Ontario heading for a record 180+ bu/ac crop

180 bushels per acre. It looks like Ontario’s 2017 corn crop is going to come in above that number and set a new record for the province. In this episode of RealAgriculture Corn School, Peter Johnson and Bernard Tobin dive into the numbers and try to figure out where all that grain came from in… Read more »

Corn School: How to reduce mechanical kernel damage

Mechanically harvesting, drying and handling grain corn can compromise quality and take a bite out of a grower’s bottom line. Earlier this fall, OMAFRA crop systems and environment engineer James Dyck worked with Dietrich Farms of Lucan, Ontario to study mechanical breakage – the impact it has on dockage and what growers can do to… Read more »

Corn School: How long does it take to add 1 percent soil organic matter?

You’ve just finished combining a corn field and you want to know how much organic matter all that corn residue will contribute to your soil. RealAgriculture’s agronomist Peter Johnson tackles that question on our latest Corn School episode. Unfortunately, as Johnson explains, all those stalks and cobs won’t have much of an impact. When it… Read more »

Corn School: Profit strategies for fixed and flex ear hybrids

Not all corn fields are created equal. Some will produce higher profits when planted with a fixed ear hybrid, others will benefit from a flex ear hybrid, and some fields will perform best with a bit of both. In this episode of RealAgriculture Corn School, Pride Seeds market agronomist Aaron Stevanus explains the basic difference… Read more »
