According to University of Minnesota Extension Soybean Specialist Seth Naeve, there is an air of mystery surrounding the soybean crop. It has been known to take a beating from Mother Nature and still deliver bushels. “The most visual example of this is when you get a really big hail event at the end of June that just completely tatters the soybeans and yet they’re able to recover and produce very good yields,” said Naeve. “The problem is we don’t know what that yield would have been had we not had that hail and it’s very, very unlikely that that hail increased the yields.” Corn is most vulnerable to stress during tasseling. The timing of stress and the impact on soybeans is a bigger question. Two years of study has identified R5-to-R5.5 as the most critical time for soybeans. Naeve addressed this topic at the Crop Pest Shortcourse in Minneapolis.
