University of Minnesota researchers are evaluating soybean varieties that can better tolerate iron deficiency chlorosis. Graduate student Isabella Fiore said researchers are studying both visual symptoms and the plants’ ability to recover later in the season. “When the plants are really susceptible to IDC, they get really yellow, they don’t photosynthesize as much, they create less biomass and at the end of the day they have less yield for the farmers,” Fiore said. “We’re looking at how they recover because some varieties bounce back better than others.” This IDC research was highlighted at Crops and Soils Day in Crookston.
