2.5. Statistical analysis
Weed control data were arcsine transformed prior to analysis of
variance but are expressed in their original form for clarity since the
transformation did not alter mean rank. Visual estimates of weed
control and soybean yield were subjected to analysis of variance to
test effects of herbicide–fungicide combinations and application
timings. Means were compared with the appropriate Fisher’s protected LSD Test at the 5% probability level.
