Title
Increased crop density reduces weed seed production without increasing screenings.

Other claims from this paper (8)
- Intervention effect Western Australian crop varieties did not show increased screenings with increased seeding rates.
- Intervention effect Increasing crop density can substantially reduce weed growth and weed seed production in the absence of in-crop herbicides.
- Intervention effect Wheat yield decreased when seeding rates increased, attributed to the extremely dry finish to the 1998 season.
- Intervention effect Triticale yield decreased when seeding rates increased, attributed to the extremely dry finish to the 1998 season.
- Observation Only triticale, and not the other cereals, showed increased screenings.
- Observation Oats were unaffected with respect to screenings.
- Observation Barley was unaffected with respect to screenings.
- Observation Other trials with different wheat varieties, seeding rates, seeding patterns and row spacings corroborated the uniformity of screenings across seeding density.
