|How to grow yams|
CONTROL OF WEEDS
For a good harvest, hoeing must be done two or three times during the early stages of growth.
When this cultivation is being done, the mounds are remade at the same time.
Later, the abundant vegetation of the yams prevents the growth of weeds.
It is then not necessary to hoe.
CONTROL OF DISEASES AND PESTS
Yams have few diseases.
However, rodents, some insects and fungi cause damage.
Damaged tubers rot quickly and cannot be kept for long.
