Table 1: Significance of main effects and interactions for percent visual injury, dry weight, height, seed moisture content, and yield of dry bean treated with PRE applications of sulfentrazone, imazethapyr, or sulfentrazone plus imazethapyr. Means followed by the same letter within a column are not significantly different according to Fisher’s Protected LSD at . Means for a main effect were separated only if there was no significant interaction involving that main effecta.
