Row Width and Maize Grain Yield (2006, background): “…on light interception and grain yield have been documented (Farnham, 2001; Flé net et al., 1996; Hodges and Evans, 1990; Ottman and Welch, 1989; Widdicombe and Thelen, 2002) when the resulting plant spatial arrangement (square or rectangular planting geometry, commonly referred to as narrow…”
Drought resistance, water-use efficiency, and yield potential-are they compatible, dissonant, or mutually exclusive? (2005, background): “Stem reserve utilisation has been found to be an effective yield-supporting mechanism under drought stress (Hossain et al. 1990; Pheloung and Siddique 1991; Gavuzzi et al. 1997; Yang et al. 2002; Asseng and van Herwaarden 2003; Plaut et al. 2004).”
Conventional and glyphosate-resistant maize yields across plant densities in single- and twin-row configurations (2011, background): “Widdicombe and Thelen (2002) reported 2 and 4% maize yield increases across two separate growing seasons when rows were reduced from 76 cm to 56 and 38 cm.”
Optimum Plant Population of Bt and Non-Bt Corn in Wisconsin (2006, background): “This observation was consistent with Widdicombe and Thelen (2002) where grain moisture decreased 5.2 and 3.5% with increasing plant populations for early and mid-season hybrids, respectively.”
Maize grain yield enhancement through high plant density cultivation with different inter-row and intra-row spacings (2016, background): “…withstand higher population densities, because they 81 can support stressful environmental conditions caused by a higher intra-specific 82 competition more easily, and this results in a lower incidence of barren plants and reduced 83 stem lodging (Tollenaar, 1989; Widdicombe and Thelen, 2002).”
Why Do Maize Hybrids Respond Differently to Variations in Plant Density (2007, background): “Other authors found similar results (Brown et al., 1970; Beech and Basinski, 1975; Widdicombe and Thelen, 2002; Edwards et al., 2005).”
Corn Response to Nitrogen Rate, Row Spacing, and Plant Density in Eastern Nebraska (2006, background): “51-m spacing is supported by the findings of others who have reported yield increases of up to 10% with reduced row spacing (Hodges and Evans, 1990; Polito and Voss, 1991; Porter et al., 1997; Ulger et al., 1997;Widdicombe and Thelen, 2002).”
Survey of Plant Density Tolerance in U.S. Maize Germplasm (2014, background): “As plant maturity is approached, the environment and plant density can influence lodging (Stanger and Lauer, 2007; Widdicombe and Thelen, 2002).”
