Nitrogen Yield and Land Use Efficiency in Annual Sole Crops and Intercrops (2006, background): “Weed community species composition could have influenced weed N uptake levels (Blackshaw et al., 2003), but this effect was not tested in our study.”
Herbicide Resistance: Toward an Understanding of Resistance Development and the Impact of Herbicide-Resistant Crops (2012, background): “Placement and timing of fertilizer can be manipulated to reduce weed interference in crops (Blackshaw et al. 2003, 2004a,b; Kirkland and Beckie 1998; Melander et al. 2003; Rasmussen et al. 1996).”
Weed species response to phosphorus fertilization (2004, methodology): “…plants per pot at the soil surface and placing them in an oven at 70 C for 96 h. Roots were extracted from the soil by a washing method outlined by Blackshaw and Entz (1995) and oven-dried at 70 C for 96 h. Shoot and root samples were then finely ground and analyzed for P and carbon (C)…”
Fertilizer, manure and compost effects on weed growth and competition with winter wheat in western Canada (2005, background): “Weeds not only reduce the amount of N available to crops but the growth of many weed species also is enhanced by higher soil N levels (Supasilapa et al., 1992; Blackshaw et al., 2003).”
Effect of nitrogen rates and weed control methods on weeds abundance and yield of direct-seeded rice (2011, unknown): “Our study supports previous findings indicating that many weeds are equally or more responsive than crops to higher soil N levels (Lintell-Smith et al. 1992; Supasilapa et al. 1992; Blackshaw et al. 2003).”
Crop Density, Sowing Pattern, and Nitrogen Fertilization Effects on Weed Suppression and Yield In Spring Wheat (2008, background): “In a study of the response of 21 weed species, wheat and oil-seed rape (Brassica napus L.) to nitrogen fertilization, wheat was among the least responsive species (Blackshaw et al. 2003).”
Nitrogen Fertilizer, Manure, and Compost Effects on Weed Growth and Competition with Spring Wheat (2005, background): “ABSTRACT weed species also is enhanced by higher soil N levels (Supasilapa et al., 1992; Blackshaw et al., 2003).”
The competitive ability of pea-barley intercrops against weeds and the interactions with crop productivity and soil N availability (2011, background): “Weed species differ in their responses to N (Blackshaw et al., 2003).”
A functional group approach to the management of UK arable weeds to support biological diversity (2006, background): “, 1999), the response to nitrogen fertiliser (Blackshaw et al., 2003; Moss et al., 2004) and the ability to invade the field body from the margins (Marshall, 1989).”
