Fig. 2. Yearly seed yield responses to residue management (RM) and trinexapac-ethyl (TE) treatment combinations for 4 yr. RM treatments: burn, flail. TE treatment legend: CK = check; EF = average of two early fall rates; LF = average of two late fall rates; ES = early spring; LS = late spring. Vertical bars represent LSDs (p = 0.05). LSD 1 is for comparison of TE treatment at the same level of RM within each year. LSD 2 is for comparison of RM at the same or different level of TE treatment within each year. In 2002, LSD TE and RM are for comparison between TE and between RM treatments, respectively, averaged across all the levels of the other factor.
