Abstract: Cassava (Manihot esculenta, Crantz) and pigeon pea (Cajanus cajan (L), Millisp.) were timely intercropped with yam (Dioscorea rotundata, Poir) to evaluate these cropping systems as potential substitute for traditional hand made structures for yam vines support. Yam grown with 'vines crept-up on cassava plants yielded 36,054 kg/ha of tubers; when vines were supported by fence-trellises the production was 37,171 kg/ha. Yield of yam grown with the vines entangled on pigeon pea plants was drastically reduced to 29,452 tog/ha. Total yield from the yam/cassava intercropping was 50,880 kg/ha during a planting to harvest cycle that lasted 10 months for yam and 18 months for cassava. This combined yield was 37% higher than yam grown as a monoculture with vines supported ty fence-trellises.
