Abstract

In a field experiment, cassava (Manihot esculenta Crantz) varieties M.4 and H.2304 were trial harvested at 6 to 12 months after planting (MAP). Fresh tuber yield was not significantly different between harvest stages of 6th to 9th MAP. Though there was increase in yield beyond the 10th month, there was increase in fibre content of tubers and deterioration in cooking quality. Contents of starch, fibre and HCN were higher and dry matter percentage lower in H. 2304 than M. 4. The HCN content, though increased up to 8 MAP. it was within the safe limit of 100 μ/g.
