Using two commercially available arbuscular mycorrhizal fungal (AMF) products, one based on Funneliformis mosseae and the other on Glomus dussii, an experiment was conducted to assess their effect on yam growth and ability to suppress nematode damage in pots. Four yam cultivars (cvs) were used: t...

The white yam/cassava production system used in Sucre and Bolivar, Colombia, is described. Data on area planted, climate, soils, and production units are given. Of the farmers surveyed, 88 percent always plant white yam with cassava, and among these, 13 percent intercrop yam/cassava/maize. Cassav...
