Abstract

Synopsis Seedlings of two varieties of Bromus inermis , Lyon and Canadian certified, produced more rhizomes when kept free of weeds than when weeds were clipped or where a companion crop was used. The production of rhizomes by Lyon (southern) was greater than was the production by Canadian certified (northern) in most instances. The addition of fertilizer did not increase significantly the development of rhizomes.
