How does nitrogen and forage harvest affect belowground biomass and nonstructural carbohydrates in dual‐use Kernza intermediate wheatgrass?

Intermediate wheatgrass [ Thinopyrum intermedium (Host) Barkworth & D.R. Dewey] is a cool‐season perennial forage grass, whose grain is commercialized in the United States as “Kernza.” Its extensive root system may help in reducing soil erosion, water pollution, and C emissions. Nitrogen fertilization and forage harvest intensity may affect the belowground biomass and nonstructural carbohydrate (NSC) concentrations, which may affect growth...
