Corn fields across Ontario are full of variable plant development and that should be a concern for growers, says University of Guelph crop researcher Dr. David Hooker. Fields are littered with areas of yield-compromising backward and slow-to-develop plants. Hooker believes corn variability is even more apparent this year due to significant weather challenges; with cold… Read More

Does timing matter in strip till? Will corn planted into fall-made strips out-yield spring strips? That’s just one of many questions corn growers are asking as strip tillage gains popularity as a reduced tillage option that delivers the benefits of conventional tillage, says Ben Rosser, corn lead for the Ontario Ministry of Agriculture, Food and… Read More

When it comes to corn fertility and higher yield, nitrogen is the star of the corn production show. But Carleton Place, Ont., farmer Mark Foster and agronomist Paul Sullivan feel it’s time potash received its share of the spotlight. At the SouthWest Agricultural Conference earlier this month, the pair shared how they have unleashed the… Read More

One of the big benefits of strip tilling corn is the ability to place fertilizer directly into the berm or strip for greater nutrient efficiency. But as growers rotate out of strip-tilled corn, how can they assess the overall fertility of a field where nutrient placement was concentrated in specific areas? On this edition of… Read More

Ontario’s cool spring is having a huge impact on the soil release of nitrogen. RealAgriculture agronomist Peter Johnson says he’s seen the impact on the wheat crop already, and growers will have to keep a sharp eye on nitrogen soil tests to ensure they’re meeting the needs of the growing corn crop. In this Corn… Read More

Imagine planting corn hybrids that could produce 40 to 80 percent of their nitrogen requirements. It’s only 10 years away, says University of Wisconsin–Madison researcher Dr. Vania Pankievicz. The breakthrough comes from a Mexican corn variety called Sierra Mixe. At the recent Innovative Farmers Association of Ontario conference in London, Ontario, Pankievicz explained that the 15-foot tall variety,… Read More

Have you ever discovered small, misshapen, poorly pollinated corn ears mixed in with a field of impressive, high-yielding cobs? PRIDE Seeds agronomist Drew Thompson received a call in August from a grower telling just this story. When Thompson visited the field he noted that no nutrient deficiencies were apparent (no firing or discolouration) so out came… Read More
