Narrative

Evaluated in monoculture and in binary mixtures with alfalfa at Grand Rapids and St. Paul, MN from 1996 to 1998. Forage yield compared to common quackgrass in monoculture was similar averaging 2.3 and 4.8 Mg ha-1 at Grand Rapids and St. Paul repectively but were lower than Palaton reed canarygrass and Orion orchardgrass which averaed 2.9 and 5.2 Mg ha-1 at Grand Rapids and St. Paul respectively. Forage crude protein, acid detergent fiber, and neutral detergent fiber avraged 160, 333, and 530 g kg-1 respectively across the two locations and two harvest years and few differences were observed among the grass species for forage quality parameters. In replicated seed production trials conducted at Roseau, NM, the seed production potential was good and averaged 434 kg ha-1 and was not different from three common quackgrass populations.
