Detailed chemical analysis of raw cassava root (RCR) and processed cassava root meal (PCRM) was assayed. Results obtained were Subjected to analysis of variance (ANOVA) as applicable to a completely Randomized Design (CRD).Significant means were separated using Duncan’s Multiple Range Test. (RDECRM) had the highest crude protein content Original Research Article
