From forages to perennial grain polycultures: illinois bundleflower‐intermediate wheatgrass dual purpose mixtures
Perennial grain polycultures are mixtures of herbaceous plants harvested for seed.These food production systems have the ecological advantages of perennial cover and diversity : agriculture modeled after natural grasslands ( Natural Systems Agriculture).Illinois bundleflower Desmanthus illinoensis ( Michx.) MacM.ex B.L.Robins.& Fern. and intermediate wheatgrass Thinopy rum intermedium ( Host) Barkworth & D.R.Dewey are two promising perennial grain species currently being bred for forage and grain production.Illinois bundleflower is a North American native perennial herbaceous warm‐season (C4) legume.Intermediate wheatgrass is a cool season grass native to central Europe, with wide adaptation and high forage productivity.Our objective was to determine seed and forage yield of these two perennials in monoculture and binary mixture in central Iowa, USA.
