A trial was conducted on-station with farmer participation at Fumesua (Forest zone), Wenchi (Forest-Savannah transition zone) and Bodwease (Coastal Savannah zone) from 2000 to 2003 and on-farm during 2002-2003. Two factors, staking and species, with two levels each were assessed using the Augment...

A major constraint facing yam producers in southeastern Nigeria is poor storage of the tubers. Farmers in the area also opine that yams grown with mineral fertilizers tend to have shorter shelf life than those grown without mineral fertilizers. This study was undertaken to evaluate the effect of ...

White or Guinea yam (Dioscorea rotundata), grown for its underground tubers, is an important food in West Africa. Progress in yam breeding is constrained by variable flowering behaviour, making hybridization difficult. Yam clones may be dioecious, monoecious or hermaphrodite with variable sex rat...

Yam was intercropped with maize, okra, and sweet potato and subjected to various periods of weed interference and weed-free regimes. The field trials were conducted for two cropping seasons at the research farm of the National Root Crops Institute, Umudike, Nigeria, 5° 29' N latitude and 7° 32' E...

Two similar experiments are described in which the effects of different mulching materials and staking on the growth, development and yield of white yam (Dioscorea rotundata) Minisetts were studied. One white yam cultivar TDR 131 was used and the treatments were: black and white embossed polyethy...

Pests and pathogens in storage are frequently identified as constraints to yam (Dioscorea spp.) production in West Africa. At a one-day workshop (International Institute of Tropical Agriculture, Ibadan, May 1995), it was recognized that nematodes, a range of fungal pathogens and insect pests caus...

A Nigerian isolate of Yam mosaic virus (YMV), genus Potyvirus from Dioscorea rotundata leaves was used to mechanically inoculate Nicotiana benthamiana (propagation host) plants from which the virus was purified. A hybridoma cell line secreting a monoclonal antibody (Mab) against YMV was produced ...

Yams (Dioscorea spp., Dioscoreaceae), grown either for their starchy tubers or medicinal properties, are important crops in the tropics and subtropics. Yams broaden the food base and provide food security and income to over 300 million people. They are vegetatively propagated and comprise both di...
