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...

Nine Nigerian populations of Scutellonema bradys, obtained from infected yam (Dioscorea spp.), were assessed following inoculation onto susceptible yam (Dioscorea rotundata) cv. TDr131 in pot and field experiments in Nigeria between 2002 and 2004. In addition, geographically separated populations...

Autor: Coyne, D.L. Akpheokhai, L.I. Adeniran, A.F.

Potato (Solanum tuberosum) production in Africa is rapidly expanding and becoming increasingly important. As its geographical production range broadens, so does its potential to host new pests and diseases. Following the discovery that potato can be affected by Scutellonema bradys, further studie...

Published studies to date have suggested that seed-yam (Dioscorea rotundata) production in Nigeria using minisett (∼0.025 kg) technology or an adapted form of the technology using larger setts (0.08 to 0.1 kg) was not profitable. But these studies were often conducted under artificial conditions ...

The root-knot nematodes (RKN), Meloidogyne spp., represent an important threat to yam (Dioscorea spp.) production in West Africa. With the aim to establish the diversity of RKN species affecting yam tubers, for control and resistance screening purposes, surveys were conducted in the main yam prod...

The rapid decline of soil fertility of cultivated lands in the sub-Saharan savannas of West Africa is considered to be the main cause of the increasingly severeconstraints of food production. The soils in this tropical area are highly fragile, and crop yields are limited bycharacteristically low ...

In Benin, yam production continues to face numerous production constraints, including yield and quality reduction by Scutellonema bradys. Implementation of efficient management techniques against this pest requires an improved understanding, including at the molecular level, of the pest. The curr...

The use of commercial inoculants containing non-indigenous arbuscular mycorrhizal fungi (AMF) is an emerging technology towards improving crop production in Africa. The present study aims at evaluating the influence of two strains of commercial arbuscular mycorrhizal fungi (AMF) products, based o...

Yam (Dioscoreaspp.) is a tuberous staple foodcrop of major importance in the sub-Saharan savannas ofWest Africa. Optimal yields commonly are obtained only inthe first year following slash-and-burn in the shifting cul-tivation systems. It appears that the yield decline in sub-sequent years is not ...
