Does Seeding Rate Affect Establishment-Year Growth and Long-term Forage Yield of Indiangrass? February 5, 2018

Recent improvements in forage yield and nutritive value of indiangrass, along with its wide range of adaptation should increase its use in bioenergy and forage production, conservation practices, and reclamation projects in the central Great Plains. This study tested five seeding rates with two varieties — 'Oto' and 'NE 54' — and the effects on dry matter production
