Cultivar-specific management for seed production of creeping red fescue
A study was conducted in the Peace River region of north-western Canada with three cultivars (Boreal, Jasper, Jasper E) of creeping red fescue (Festuca rubra L. var. rubra) to identify cultivar-specific management practices for seed production. Experimental treatments included four methods of establ...

A study was conducted in the Peace River region of north-western Canada with three cultivars (Boreal, Jasper, Jasper E) of creeping red fescue (Festuca rubra L. var. rubra) to identify cultivar-specific management practices for seed production.
