Soybeans in Manitoba are around the fourth to fifth trifoliate stage, with some crops beginning to flower this week.
Manitoba Pulse and Soybean Growers production specialist Kristen Podolsky says this is a reminder that producers should be getting their last herbicide applications in. It's also the time for grower to be making nodulation assessments.
"What you should be looking for is at least 10 nodules per plant," she says, "that's what research has found to be the number to optimize yield. Then, if you break open some of those nodules, they should be pinkish-red inside."
