Abstract

Intermediate wheatgrass (IWG), when grown for perennial grain Kernza®, provides producers with marketable grain and forage for multiple growing seasons. Agronomic information is limited for crop production in Kansas. This study provides first and second year baseline morphological growth and development of IWG [Thinopyrum intermedium (Host) Barkworth and D.R. Dewey] in Kansas; assesses spring and summer forage quality and quantity; and evaluates the intercropping potential of alfalfa Medicago sativa L. Wide and narrow row spacings (30.5 and 61 cm), spring-applied urea (80 kg ha^-1), elite alfalfa germplasm, and one non-nitrogen fixing alfalfa treatments were used to compare effects on growth index stage progression, plant height, biomass accumulation and partitioning, crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) for IWG. These responses were highly significant when regressed with accumulated growing degree days (GDD) (P
