CK: cottonseed shell blank culture medium inoculation. DSE: P. bamuru A024 inoculation alone. CK + SH: Single inoculation with R. solani SH01. DSE + SH: sequential inoculation with P. bamuru A024 and R. solani SH01. Diverse letters within each column are indicative of significant differences (p < 0.05) upon Tukey test.
