aMeans within a herbicide resistance trait followed by the same letter are not significantly different according to Fisher’s Protected LSD test at P 0.05. Data are pooled over postemergence herbicides. bLow and high soybean populations were 145,000 and 464,000, respectively. cS-metolachlor and S-metolachlor plus fomesafen applied at 1500 and 1200 + 270 g ha−1, respectively. dGlufosinate and glyphosate applied to appropriate herbicide-resistant cultivar at 560 g ha−1 and 840 g ha−1, respectively. |
