    Developing Agronomics of Intermediate Wheatgrass as a Perennial Grain
    (2017-08) Frahm, Charles
    The forage species intermediate wheatgrass (Thinopyrum intermedium L.; IWG) is being developed for use as a perennial grain crop. Field tests have shown that improved IWG populations are suitable for many food applications, creating demand for IWG grain. A lack of understanding of IWG characteristics related to grain production has limited the ability for researchers to recommend best management practices for increasing grain yields. By describing IWG development through quantitative modeling, useful information was generated to apply practical management decisions in future production of IWG. A production challenge limiting IWG grain production is stem lodging, which hinders pollination, grain fill, and reduces overall grain quantity. The second objective of this research was to measure the effect of plant growth regulators (PGRs) on IWG grain yield. Results show that applying PGRs at rates recommended for other grass species has the potential to increase IWG grain yields.
