In-Season Prediction of Corn Grain Yield Potential Using Normalized Difference Vegetation Index (2006, background): “Varvel et al. (1997) reported that maximum grain yields in corn could not be realized due to lost yield potential when severe N deficiencies occurred at V8; however, Scharf et al. (2002) found that N applications (no preplant N) could be delayed as late as V11 with no yield loss and only minor yie”
Using Relative Chlorophyll Meter Values to Determine Nitrogen Application Rates for Corn (2007, background): “Russelle et al. (1983) also found that when N applications were delayed to V16, the time of greatest N uptake was generally delayed until after R1. Scharf et al. (2002) found that when N application to corn was delayed until V12 to V16 there was a small but significant yield reduction.”
Effect of fertilizer application on photosynthesis and oil yield of Jatropha curcas L. (2010, background): “Detailed studies on how fertilizer application affects plant physiology and improve crop yield have been carried out for many commercial crops such as corn, wheat and rice (Scharf et al. 2002, Jiang et al. 2004, Stewart et al. 2005).”
An active sensor algorithm for corn nitrogen recommendations based on a chlorophyll meter algorithm. (2010, background): “Scharf et al. (2002) also found that irreversible yield losses were less likely to occur when N applications occurred by V11 compared to applying N at later growth stages.”
Chlorophyll meter readings can predict nitrogen need and yield response of corn in the north-central USA (2006, background): “There is evidence that corn can withstand N stress and rebound to produce full yield until well into the vegetative growth stages ( Scharf et al., 2002; Binder et al., 2000; Russelle et al., 1983; Miller et al., 1975), but also that early-season N stress sometimes irreversibly reduces yields (Binde”
Maize response to nitrogen fertilization timing in two tillage systems in a soil with high organic matter content (2007, background): “In addition, it may decrease the disparity of yield losses due to N stress if rainy springs delay the planned side-dress application time (Scharf et al., 2002).”
EFFECT OF DELAYED NITROGEN FERTILIZATION ON MAIZE (ZEA MAYS L.) GRAIN YIELDS AND NITROGEN USE EFFICIENCY (2012, background): “Scharf et al. (2002) found N fertilization even as late as the 11-leaf vegetative stage (V11) did not result in irreversible yield loss for maize showing very significant N stress.”
A visible band index for remote sensing leaf chlorophyll content at the canopy scale (2013, methodology): “Digital cameras and aerial photography are low-cost methods used for determining areas with nitrogen deficiency (Blackmer et al., 1996; Adamsen et al., 1999; Scharf et al., 2002a; Dani et al., 2005).”
Plant Density and Nitrogen Effects on Maize Phenology and Grain Yield (2009, background): “Grain yield in maize increases with increase in plant density, rate and spit application for N ( Mariga et al, 2000 ; Scharf et al, 2002 ).”
Association of “Greenness” in Corn with Yield and Leaf Nitrogen Concentration (2011, background): “Scharf et al. (2002) found that N application to N defi cient corn at tasseling positively aff ected grain yield; however, Binder et al. (2000) found that to avoid substantial yield losses, N must be applied before tasseling.”
