A reliable means to induce sprouting in dormant seed tubers of yams (Dioscorea species) is required to enhance flexibility in planting date and rate of propagation of the crop. Experiments were conducted to assess the potential of two gibberellin inhibitors, Uniconazole-P and Prohexadione-calcium...

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.

The effects of boiling on the microstructure of yams and their association with the textural quality of “boiled yam,” arguably the most common food product from yams, were studied using six varieties with variable cooking qualities from each of the two species, Dioscorea alata L. and D. rotundata...

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...

Based upon IBPGR (IPGRI) morphologic descriptors, 560 accessions of Benin Republic's cultivated yams (Dioscorea ccayenensis/Dioscorea rotundata complex were morphologically characterized. Ninety morphotypes were identified and accessions were classified into 26 varietal groups according to their ...

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 ...
