Weedy rice in sustainable rice production. A review (2017, background): “Weedy rice was found to produce six times more root tips and three times more shoot biomass compared to cultivated rice when subjected to nitrogen deficiency (Burgos et al. 2006; Sales et al. 2011).”
Reducing the Risks of Herbicide Resistance: Best Management Practices and Recommendations (2012, background): “In rice production, weedy rice takes up about 60% of applied N (Burgos et al. 2006), giving it a competitive advantage over the crop, leading to greater seed production and increased risk of herbicide-resistance evolution.”
Weed Ecology and Weed Management Strategies for Dry-Seeded Rice in Asia (2012, background): “Weeds can have a higher nutrient requirement than crops and compete strongly for nutrients, even when high rates of fertilizer are applied (Burgos et al. 2006; Chauhan and Johnson 2010b, 2011c; Malicki and Berbeciowa 1986).”
