Generally results from all the trials conducted consistently showed that soil and location factors affected the physical and chemical characteristics but not the organoleptic quality of both cassava and ubi. Bohol [ Philippines] grown cassava had the highest percentage of dry matter and other chemical constituents in the roots while those planted in ViSCA [Baybay, Leyte, Philippines] obtained the highest moisture content. Organoleptic test revealed that cassava roots were all acceptable in all locations and soil used, although in Bubon and Loon grown roots gave relatively low ratings because of the slight bitterness of cooked roots. HCN contents of the roots in these location were found to be highest. Similarly ubi tubers planted in Bohol generally showed higher percentage of the dry matter and other chemical constituents than the ViSCA grown tubers. However, the sensory qualities of the tubers were similar in all locations. Although Bohol grown tubers numerically obtained high scores, they did not differ significantly from the ViSCA grown tubers
