Growers and agronomists typically focus on the ear leaf at flowering when tissue testing corn to determine nutrient needs. But is that still the best choice for determining the optimal nutrient prescription for the crop as it moves into the reproductive stages? Purdue University professor emeritus Dr. Tony Vyn believes the evolution of modern hybrids… 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
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
We’re celebrating the fifth Monday of January in style with this week’s edition of the RealAg Radio agronomy show. Your host Shaun Haney is joined by none other than RealAgriculture’s agronomist and general wheat enthusiast Peter Johnson to tackle your biggest agronomy questions, such as if winter crops have died all their deaths yet. They… Read More
If you’re targeting maximum corn yield, you need to fine-tune plant nutrition for a particular two-week period of the corn growing season, says Tony Vyn, professor of agronomy at Purdue University. That’s because while we’ve been focused on more rows and kernels per row per ear, modern hybrids can pack tonnes of yield in if… Read More
Talk of banding versus broadcasting nutrients is likely to become a much bigger conversation as Ontario works to reduce the impact farm phosphorous on the Great Lakes. In this Corn School episode, Purdue University professor Tony Vyn offers insights on why he feels farmers should consider banding nutrients as apposed to broadcasting. While attending the… Read More
These aren’t your daddy’s corn hybrids. If you think modern corn hybrids are leaps and bounds more productive than what you were planting 15 or years ago, you’re right. But thinking so and knowing so (and how) are two different things, and for that you need research. Tony Vyn, of Purdue University, has looked at… Read More
Everyone has an aunt or an uncle or someone that uses “blanket” terminology. You know what I mean, they call blu rays and CD’s DVD’s or call all mp3 players “iPods”. We’re all guilty of it on some level, but the truth is terminology is important. Just ask Tony Vyn about using the terms “drought… Read More
Potassium is critical for in-plant water management, which means that adequate levels of the nutrient at various depths is a key component of how well a crop handles drought stress. While no one can accurately predict a drought, managing overall soil health and nutrient levels is a great way to add some drought risk management… Read More
The 2012 drought that hit Ontario producers hard, hit Indiana farmers even harder. So hard in fact that it was one of the worst yielding crop years on record. That number being relative to what’s expected given technology and management practices of the time. Needless to say, that puts drought tolerance as an issue that’s… Read More
