- Biochemical analyses were carried out to determine the changes that occurred in two varieties of cocoyam (var. esculenta and var. antiqourum (L.) Schott (Hubbard & Render) corms and cormels inoculated with Alternaria alternate, Fusarium oxysporum, Verticilium lateritium, Botrydiplodia theobramae, Colletotricum coccoides, Phythium myriotylum, Fusarium verticillioides, Rhizopus stolonifer and Geotricum candidum. Significant increases (P0.05) were observed in moisture, protein, crude fat, fiber and ash contents of the two varieties of the cocoyam corms and cormels inoculated with the fungi during the 14-day period of incubation, when compared with the un-inoculated corms and cormels. In the var. esculenta, A. alternata, B. theobromae, P. myriotylum, F. stolonifer, F. verticillioides, F. oxysporium, G. candidum, C. coccoides and V. lateritium increased the moisture cntent, protein content,crude fat content,fiber content and ash content in corms and cormels incubated for 14 days in complete darkness at 25° C ± 2 C, when compared to their controls. The nine fungi caused a significant (P
