There are certainly unknowns and risks that come with planting bin-run soybean seed versus certified seed, but one significant piece of information has been confirmed by crop insurance data in Manitoba: older, off-patent varieties don’t have the same yield potential as newer varieties. As Dennis Lange, pulse specialist with Manitoba Agriculture, points out in this… Read More

Does throwing the kitchen sink at your soybean crop provide an economic yield response? The answer is a definitive “No” says University of Minnesota associate professor Seth Naeve. His conclusion is based on the the results of a huge three-year U.S. study that he shared with growers attending the Southwest Agricultural Conference in Ridgetown, Ont.,… Read More

Most of the yellow patches in soybean fields in Western Canada and the northern U.S. have disappeared as the plants have recovered, or turned necrotic and died, but one of the big questions heading into harvest is: what toll did widespread issues with iron deficiency chlorosis (IDC) earlier in the season take on yields? The… Read More

It pays to steer clear of those corn rows when planting soybeans. In this episode of RealAgriculture Soybean School, Syngenta agronomist Eric Richter explains that planting directly on, or too close to, last year’s corn row produces seed mortality rates between 50% to 80%. He notes that it really doesn’t matter whether growers are pulling… Read More

Not only are there legalities that need to be considered when purchasing and planting off-patent soybean seed, as we discussed in an earlier Soybean School feature, but there are also agronomic considerations. Due to the nature of the off-patent soybean seed market, assurances for the grower on maturity, germination, quality, and purity are often lacking… Read More

How have soybeans changed over the past century, and what can growers learn from this evolution? Purdue University agronomy professor Shaun Casteel has some answers. Speaking at the recent Ontario Certified Crop Advisor annual conference, Casteel shared insights from his research comparing varieties from 1923 to those available in 2011. In this episode of Real… Read More

Preliminary results from a three-year research project in North Dakota show row spacings in many soybean fields are too wide to reach their maximum yield potential. A team of agronomists and extension agents at North Dakota State University are surveying growers to generate baseline data on soybean management practices in the state. Their goal is to… Read More

The amazing rise of soybean acres across Manitoba and into Saskatchewan is possible only because of the development of early, early soybean lines. Just how early? While zeros and double zero maturity ratings are great for “short” season areas in Ontario and Quebec, it’s the triple zero lines that shine in places like Arborg, Manitoba,… Read More

Fifteen years ago, University of Guelph’s Dr. Clarence Swanton helped revolutionize weed control with his pioneering research on the critical weed-free period for soybeans and corn. Essentially, Swanton helped usher in the thinking that weeds that emerge with or shortly after the crop cause irreversible yield loss. He defined the critical weed-free period as 1st… Read More

The first secret of soybean success really isn’t much of a secret, confesses agronomist Ross Bender. It all comes down to the weather, specifically rain in August. But farmers do have an opportunity to impact the remaining production factors that make up the six secrets of soybean success, says Bender, senior agronomist for the Mosaic… Read More
