Potential Synergistic Effects of Cereal Rye Biomass and Soybean Planting Density on Weed Suppression (2011, background): “Increasing crop interference with weeds by increasing crop seeding density and spatial uniformity can be an effective cultural weed management tactic (Hock et al. 2009; Jordan 1993; Weiner et al. 2001).”
Crop Density, Sowing Pattern, and Nitrogen Fertilization Effects on Weed Suppression and Yield In Spring Wheat (2008, methodology): “These results are consistent with those of our other studies (Olsen et al. 2005a,b, 2006; Weiner et al. 2001), and they also support the notion that increased wheat density and spatial uniformity can play an important role in weed management under a wide range of nitrogen inputs.”
Heteromyopia and the spatial coexistence of similar competitors (2002, background): “A striking application of this is in the use of cereal crop plants to control their weeds: much more effective control can be achieved by switching from the current practice of sowing cereals in rows to sowing them on lattices ( Weiner et al. 2001 ).”
Integrating physical and cultural methods of weed control— examples from European research (2005, background): “Crops planted in rows allow for weeds to use the light between the rows, whereas crops that are uniformly distributed are better at competing with the weeds, resulting in a 30% decrease in weed biomass (Weiner et al. 2001).”
Sustainable weed management in direct seeded rice culture: a review. (2013, background): “Combination of increased crop density and more uniform plating for better weed suppression has been emphasized by many researchers (Weiner et al., 2001; Boyd et al., 2009), who concluded that row seeding allows for weeds to utilize the light between the rows, while evenly distributed crops compete…”
Increased density and spatial uniformity increase weed suppression by spring wheat (2005, positive): “Furthermore, the clumped pattern reduces the potential for increasing weed suppression with higher crop densities, because increasing crop density within rows increases intraspecific competition within the crop population more than it increases competition with the weeds (Weiner et al., 2001).”
The Weed-Competitive Ability of Canada Western Red Spring Wheat Cultivars Grown under Organic Management (2007, background): “Much of the Canadian wheat competition research has involved the use of cultivated crop plants like A. sativa L., Brassica juncea L., and B. napus L. (Huel and Hucl, 1996; Weiner et al., 2001 ) or sown densities of wild oat (A. fatua L.) (Kirkland and Hunter, 1991) as weed analogs.”
Influence of sowing density and spatial pattern of spring wheat (Triticum aestivum) on the suppression of different weed species (2006, methodology): “Under very high weed pressure, a combination of high crop-sowing density and increased spatial uniformity resulted in a 60% reduction in weed biomass and a corresponding reduction in crop losses due to weeds in comparison to normal sowing practise (Weiner et al. 2001).”
Investigating the selectivity of weed harrowing with new methods (2008, background): “…& Svenningsen, 1995), but this study showed that selectivity only was affected by row spacing in the late GS 21, indicating that early post-emergence weed harrowing may be used successfully in narrow rowed cropping systems like the spatial uniformity system proposed by Weiner et al. (2001).”
Reliability of higher seeding rates of wheat for increased competitiveness with weeds in low rainfall environments (2004, background): “Row spacings and planting patterns can also produce a more competitive crop stand and in some cases the advantage can be large (Weiner et al. 2001).”
