Age assessment of two cassava cultivars on yield and quality of Gari

Abstract

This study investigated the age effects of cassava roots on GARI yield and quality through the assessment of chemical analysis of two cassava varieties that were processed into gari, OKO IYAWO and TME 419; 12, 15, and 18 months of each of the cassava roots were selected. Chemical analyses done on the samples were: pH, total titratable acidity (TTA), total crude fiber (TCF), ash contents (AC), and moisture contents (MC). The results were pH of OKO IYAWO: 3.65, 4.00 and 3.75; pH of TME 419: 3.75, 4.00 and 4.21; TTA of OKO IYAWO: 0.85, 0.93 and 0.87; TTA of TME 419: 0.97, 0.95 and 0.84; TCF of OKO IYAWO: 2.77, 1.92 and 2.19; TCF of TME 419: 3.63, 1.82 and 1.62; AC of OKO IYAWO :1.30, 1.30 and 1.34; AC of TME 419: 1.24, 1.31 and 1.31; MC of OKO IYAWO: 3.7, 3.90 and 5.00; MC of TME 419: 5.5, 2.90 and 2.40. SI of OKO IYAWO: 2.80, 2.88 and 3.00; SI of TME 419: 3.00, 3.08 and 2.92 for 12, 15 and 18 months respectively. Finally, Gari yield values of OKO IYAWO cassava were 24%, 26% and 27% for the age of 12, 15 and 18 months respectively however, Gari yield of TME 419 cassava were 35%, 34% and 18% for the age of 12, 15 and 18 months respectively. The chemical analysis done were within the standard recommendation.
