| Sumario: | Current methods and the importance of supporting yam vines and the significance of the yam crop in W. Africa are discussed. A support system based on the in situ stems from bush fallow was developed in Nigeria. The yield of yams was lower with in situ stems at 1.5 X 1.0 m spacings than with conventional staking at 1.0 X 1.0 m spacings but yields were similar when both support systems were at 1.5 X 1.0 m spacings. Leucaena leucocephala gave suitable support stems in 1-2 yr. The yields of yams given when L. leucocephala was used in a horizontal support system (tops and small branches thrown on the ground) or as conventional stakes were 25.5 and 25.9 t/ha, respectively. |
