Get a Suitable Farmland for the Yam
The yam business is set up on a large parcel of land, not your backyard please. The condition of the soil on the land is also crucial. Uplands with sandy loam or silt loam soil are your best choices. So those living in forest areas have the ideal soil for planting yam.
Preparing the Land
Once the land had been cleared, you can now prepare the heap or ridge beds. Whichever one you use, it should be one meter high and one meter apart, and all beds must be built in line with the land’s contour to mitigate erosion.
Preparing your Setts
Sets are simply the yam ‘seeds’ to be planted. These are small pieces of the yam tuber, like the heat sett, the middle sett and the tail sett, including a whole tuber, it depends on the size of the sett. You should get your setts from healthy yam tubers.
The cut sets should be treated with ash or fungicide and then aire dried. Once this is done, you can either pre-sprout the setts or plant directly. Pre-sprouting is advised to reduce wedding and give you assurance that the setts would grow.
White yam is usually planted between march and April depending on when setts are sprouted or when rainy season actually begins in that area. One hectare of land can accommodate between 20,000 to 27,000 setts. Both pre-sprouted and non-pre-sprouted setts are planted at about the same time and in the same way.
You know it’s time to harvest your yams when the leaves and stalk start getting yellow or begin drying up. This usually occurs as from November and up to February the following year. Your commercial tubers will be harvested at the early stages even before yellowing and drying up. While the tubers to be made into setts will be harvested much more later.
