Perhaps you’re already acquainted with the wild world of theoretical yields. A theoretical yield is a measure of the genetic potential a plant has, if absolutely nothing hampered yield — not the growing season, environment or pests. Can you guess what soybeans’ theoretical yield is? Roughly 350 bushels an acre. Outlandish? Well, it sort of… Read More

You’re looking at yield data from last year trying to figure out which soybean varieties to grow in 2015 — how do you know when the yield difference between two varieties is meaningful? “That’s a question we get all the time when it comes to picking varieties and looking at single-year site data,” says Dennis… Read More
While research shows fungicide applications in wheat and corn can often be justified by higher yields, the yield response to fungicides in soybeans is not as clear cut. Timing of fungicide application might be part of the formula for getting better than break-even returns, says Dave Hooker, field crop agronomist and assistant professor at the University of… Read More
It’s a disease that affects a number of significant crops in Canada, including vegetables, pulses, canola and even some forage species. And last year, some farmers saw particularly high levels of white mould in soybean crops across Ontario. Sclerotinia sclerotiorum, or white mold, makes its mark on plants in lesions that appear water-soaked; white, fluffy mycelium;… Read More
Start clean, stay clean is a smart motto when it comes to corn and soybean fields, but what’s the right amount of “clean” in relation to weed cover and yield potential? Dr. Peter Sikkema, professor of plant science with the University of Guelph — Ridgetown Campus, took to the field to answer that question. If,… Read More
Manitoba farmers whose soil test results say they have soybean cyst nematode in their soil may want to get a second opinion, says a soil ecologist from the University of Manitoba. While the number of soybean acres has exploded on the eastern side of the Prairies over the last few years, Western Canadian growers have… Read More
White mould love tight soybean rotations. What’s the best plan of attack for 2015? A good chunk of wheat acres didn’t get planted in the fall of 2014, during what some have dubbed a “harvest from hell.” Many of those acres are likely to go into soybeans, and for good reason. But, agronomically, it’s not… Read More
This year’s growing season is not likely to be forgotten for a very long time — and, unfortunately, not for great reasons. A late, wet, tough spring, widespread white mould in the beans and down-right cold break in the summer all cumulated in a long, drawn out harvest that’s headed into the holiday season for… Read More
Want to know what buyers look for in a soybean sample? Or what you don’t want to see in your soybeans? This episode of the Soybean School takes us to the Canadian Grain Commission grading lab in Winnipeg. Thanks to Daryl Beswitherick, program manager for quality assurance and re-inspection at the CGC, for taking some time… Read More
If the soybeans are mature, but a wee bit damp yet, do you let them stand or get them in the bin so you can dry them down? Helmut Spieser, agricultural engineer with the Ontario Ministry of Agriculture, Food and Rural Affairs, would call leaving the beans out a “gutsy” move, and not one that’s… Read More
Can deep-tilling soybean residue be justified? A researcher from the University of Manitoba is looking at whether tillage practices need to change as farmers in Western Canada grow more soybeans. Despite leaving less plant matter behind than most crops, it’s not uncommon to see soybean ground cultivated to leave a dark surface that warms up and dries out… Read More
A cool, wet summer has left many Ontario soybean fields with some level of white mould infection. The fuzzy white stem rot could be seen in patches across many fields by late summer, sometimes causing large areas of loss in a field. A key element of controlling or avoiding this disease is understanding how it… Read More
For the lucky soybean growers who still have maturing and not frosted soybeans on their hands, this post on pre-harvest management of the crop is for you! (And for you farmers in the east stung by the September frost, we’re sorry, and maybe keep all this info in mind for next year.) There are solid… Read More
Soybean growers in Western Canada and the Northern U.S. have been up early over the last few mornings checking how low temperatures dropped overnight. The thermometer has dipped below the freezing mark in some areas, with damage to soybeans depending on a number of factors, including maturity. As part of this Soybean School West episode, Kristen Podolsky,… Read More
So you’re thinking of switching to a wider row spacing for next year’s soybeans. Have you taken your hula hoop around this year’s crop first? Though there isn’t necessarily an “ideal” row spacing suggested for western Canadian soybean growers, the importance of knowing a target plant population and assessing stand establishment is still essential.
