Rice–wheat cropping systems in South Asia: issues, options and opportunities (2019, background): “Optimum seed rate and plant geometry, and proper N management and use of crop residue must be considered for better weed control and management (Chauhan and Johnson 2010a, 2010c, 2011a, 2011b; Chauhan et al. 2011; Mahajan and Chauhan 2011).”
Productivity and sustainability of the rice-wheat cropping system in the indo-gangetic plains of the Indian subcontinent: Problems, opportunities, and strategies (2012, background): “Since the conditions are not conducive for perfect seedling emergence in the farmers' fields, the seeding rate should be kept higher than 15 kg ha 1 to compensate for damage by rats and birds, to partially overcome the adverse effects of herbicides, and to compensate for poor stand establishment if ”

Weed Ecology and Weed Management Strategies for Dry-Seeded Rice in Asia (2012, background): “In DSR, crop interference reduced the height of barnyardgrass [Echinochloa crus-galli (L.) Beauv.] and ludwigia [Ludwigia hyssopifolia (G. Don) Exell] but did not affect the height of rice flatsedge (Chauhan and Johnson 2010c; Chauhan et al. 2011a).”
