Make ridges 

And if planting in sacks fill up the sacks (bags) with soil.

Step 3 – Seed Selection when Planting Yam

Yam is propagated through seed yams (small whole yam) or setts (cut pieces of yam)

Recent development or technique shows that yam can be grown through the stem or vine cuttings.

We have various species or varieties of Yam in Nigeria, 

These varieties are named by location where they are grown e.g Ebira Yam, Zaki Ibiam Yam, Onitsha Yam etc.

And newer varieties come with there given names e.g UMUDa-27 (TDa1100201), UMUDr-18 (TDr 89/02475)

Seeds or setts stored from the last harvest can be used as well.

How to make yam setts

Treat the cut with wood Ash

Step 4 – Plant the Seed

With seed yam:

On the ridge, push in the seed yam into the soil or make a hole on the ridge enough to take the tuber with the yam head upward, cover up with soil.

With yam setts:

On the ridge make a hole enough to accommodate the yam setts and ensure the tip faces upward.

To plant the yam, you have to Finally plant the Yam into ridges or bags with the tip planted upward. The yam should go deep into the soil.

The spacing between each plant should be 40 cm (15.7 in) by 75 cm (29.5 in).

To plant with sacks:

Be careful with the plant when stalking and avoid getting the stem cut.

Yam take about five to seven months to mature, depending on the variety.
