Variability in elephant foot yam following hybridization and open pollination.
Stimulating the sprouting of yam tubers with ethephon.
Yam tubers without blemish and about 10 cm in diameter and 20 cm in length were regarded as ware tubers.
Effects of cultivations and heights and directions of staking on yield and general performance of eight yam cultivars.
Most tubers from cultivated yams are elongated cylinders rounded at both ends.
In the sub-plots of 10.5 m x 9.5 m, eight rows of pumpkin bordered 10 rows of yam with the rows 0.50 m apart.
The tubers in both the yam barn and the growth chamber were kept in moist coir, such that all were subject to similar humidity.
The same observation is true for yam mucilage.
