Other claims from this paper (13)
- Association Improved perennial ryegrasses were no more competitive toward Kentucky bluegrass seedlings than annual ryegrass.
- Observation Improved perennial ryegrasses provided rapid initial cover.
- Mechanism Persistence of perennial ryegrasses allowed bluegrass encroachment during the seedling year.
- Mechanism Ryegrass seedling competition was not due to seed or seedling excretions.
- Association Turf quality with improved perennial ryegrasses exceeded annual ryegrass but was slightly below pure bluegrass.
- Association Redtop and creeping red fescue were less competitive with bluegrass than ryegrasses.
- Association Turf quality of redtop and creeping red fescue mixtures was similar to pure bluegrass.
- Intervention effect Higher seeding rates offered no advantage above 5% PLS.
- Association Fall seeded mixtures contained the most Kentucky bluegrass.
- Association Summer seedings contained the least Kentucky bluegrass.
- Intervention effect Low clipping reduced companion grass competition and allowed transition to bluegrass dominance.
- Association Pure bluegrass turf had the best sod strength.
- Observation Improved perennial ryegrasses had the best root development.
