Treatment with indolebutyric acid (IBA) significantly increased the number of roots produced by vine cuttings of ten Dioscorea rotundata cultivars. Some cultivars could be propagated by layering, especially with IBA treatment, but layering does not appear to be feasible for use on farms.

A better knowledge of traditional cultivars is a prerequisite to overcoming the various constraints of yam production in Benin. Using IPGRI's descriptors, 560 accessions of cultivated yams (D. cayenensis Lam./D. rotundata Poir. complex) collected throughout Benin, were characterised. Ninety morph...

Yield decline in yam may not only be due to soil nutrient depletion but also to the activity of soilmicroflora. Arbuscular mycorrhizal (AM) symbiosis helps in plant nutrition but may be affected bythe application of fertilizer. The effects of nitrogen (N), phosphorus (P), and potassium (K) fertil...

This study investigated pasting and sensory characteristics of Dioscorea?alata, an underutilized yam species, to ascertain its suitability for amala (a pasty yam product) in comparison with D.?rotundata. Pasting was determined by Rapid Visco-Analyser and the amala was prepared from parboiled and ...

Yam is the third most important root and tuber crop in the tropics but few species are grown as health food and/or for medicinal purposes. To ascertain the potential health benefits and alternate usage of the species, 20 varieties of Dioscorea alata (water yam) were investigated for their total d...

The diversity of arbuscular mycorrhizal (AM) fungi in soils under a yam cropping system in four agroecologies of Nigeria was investigated. Soil samples were collected from yam fields at Onne (humid forest, high rainfall area), Ibadan (derived savanna), Abuja (Guinea savanna) and Ubiaja (humid for...
