Interactions of Nitrogen Source and Rate and Weed Removal Timing Relative to Nitrogen Content in Corn and Weeds and Corn Grain Yield

Figure 1

Nitrogen (N) content in Palmer amaranth plants as influenced by N rate and average weed size at timing of removal. Means followed by the same letter are not significantly different based on Fisher’s protected LSD test at . Data are pooled over years, locations, and N sources.
