|Table 1: Percent reduction in soybean fresh weight and dry weight at harvest (40 days after emergence) caused by early season interference by Palmer amaranth in greenhouse experiment.a,b|
|Data are pooled over runs of the experiment. Abbreviations: GR, glyphosate resistant; GS, glyphosate susceptible.|
Means within a parameter and analysis followed by the same letter are not significantly different according to Fisher’s Protected LSD test at P ≤ 0.05 for fresh weight reduction and P ≤ 0.10 for dry weight reduction.
Consists of six Palmer amaranth biotypes.
Consists of a group of three glyphosate-resistant (GR) and a group of three glyphosate-susceptible (GS) Palmer amaranth biotypes.
