How to Grow Cassava
Step 1: Cut fresh cassava stems into pieces of about 15 cm long. Each piece must have viable bud eyes.
Step 2: Measure the planting distances of about 90 cm apart on the ridge or flat.
Step 3: Push the cut stem into the ridge or flat at the 90 cm distances in a slanting position making sure that the buds are facing upwards. Continue in this manner until the plot is planted up.
Step 4: Check for sprouting two or three weeks after planting and replace the dead sticks.
Step 5: Apply NPK fertilizer about five weeks after sprouting.
Step 6: Carry out the first weeding and remold the ridges.
Step 7: Do the second weeding after about 6 months.
Step 8: Check for maturity 12-18 months after planting, depending on the variety planted.
Step 9: Harvest the tubers and process within 3 days of harvesting.
