Title
Increased crop density reduces weed seed production without increasing screenings.
S. Peltzer; A. C. Bishop; M. Boersma; et al. 12th Australian Weeds Conference, Papers and Proceedings, Hobart, Tasmania, Australia, 12-16 September 1999: Weed management into the 21st century: do we know where we're going? 1999
Other claims from this paper (8)
- Intervention effect High seeding rates reduced weed seed production to manageable levels in all four cereals (oats, barley, wheat, triticale).
- 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.
