Description

Trials were seeded in 1993 at Saskatoon SK and Brooks AB, Canada and assessed in 1994 and 1995 to examine the impact of residue management, row spacing and seeding rate on seed yields of Kentucky bluegrass, creeping bentgrass, and creeping red fescue, with the focus primarily on Kentucky bluegrass. The highest, most consistent yields were achieved in the first production year, and yields were generally highest at narrow (20 - 40 cm) row spacings at that time. Without aggressive residue management such as burning or close mowing (scalping), yield of all three species declined dramatically in the second harvest year (less pronounced at wide row spacing). Aggressive management consistently produced higher yields than mowing or baling, but even the best yields were lower than those in the first harvest. Seeding rate did not have a consistent effect on Kentucky bluegrass seed yield, and residue management did not affect the incidence of silvertop.
