What is the difference between yam seed and seed yam?
Seed yam ready for planting. Tubers produced from seed yam are genetically identical to the mother seed material, while those produced from yam seeds have an identity different from the parent material. In West Africa, farmer-saved seeds are the predominant source of planting material (Nweke et al. 2011).
How many months does it take yam to mature?
Depending on the variety, yams are harvested 6 to 12 months after planting. Lift the tubers when the leaves and stems turn yellow and dry. Do not leave the ripe tubers too long in the ground, otherwise they become bitter and may rot. With some varieties, only one crop is harvested.
What is a seed yam?
Seed yams are being mass produced by scientists in a rapid and affordable process, which avoids using soil and transferring disease. A project in Ghana and Nigeria is using aeroponics to address the inefficiency of traditional seed yam production and increase yields of the staple crop.
How many yams can be planted on a plot of land?
Yam farming is lucrative a 100 by 100 plot of land can produce up to 10,000 tubers.
How do you prepare a soil for yams?
Yams require deep, loose, textured loamy soil that is rich in organic matter. They are best planted at the beginning of the rainy season. Mulch around the planted sets protects them from excessive heat and desiccation, especially in areas with hot temperatures and dry weather.

Synergistic use of oil palm bunch ash + poultry manure at 10 t ha−1 each was most effective for sustainable management of soils and for improving agronomic productivity of yam.
