PRODUCTION OF TUBER CROPS(CASSAVA)

Back to: Agricultural Science Primary 6

Welcome back to class

 

Last lesson we learnt about the steps taken in the production of maize which is a cereal. In today’s lesson, we will look at the production of cassava. Cassava is a tuber. Other examples of tuber crops are sweet potatoes, Yam, Cocoyam, Irish potato and Carrot.

ACTIVITY

1. What is the major nutrient that these food crops give?
2. State the major function of the food nutrient mentioned above.

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.
