Figure 1. Corn grain yield as impacted by timing of sidedressing (NoN = starter only; Nrich = 300 lbs N per acre at planting; V4, V6, V8, and V10 = sidedressing of 180 lbs N per acre at the designated growth stage). The trials were conducted on continuous corn fields without a recent manure history at the Musgrave Research Farm in Aurora, NY). The values above each bar indicate the mean yield. Yield are not statistically different if followed by the same letter (a, b, etc.).
