Summary

Results of a 2-year study in a rainforest zone of south-western Nigeria to determine the effects of various planting and harvesting times on the yield, HCN, dry-matter accumulation and starch contents of cassava showed that times of planting and harvesting significantly affected all the variables studied. May planting gave highest yield arid starch contents, which suggests that large-scale production of cassava for industrial starch and human consumption should be planted in the month of May.

The harvesting time experiment shows that cassava tuber will continue to increase until the 24th month, although, because of increasing demand for land, it will not be economic to leave cassava on the field for more than 15 months. For optimum starch and dry-matter accumulation, cassava should be harvested between 12 and 15 months.
