Scarcity and/or high cost of healthy seed yams are the greatest constraints in yam production in Nigeria and probably across the West African Yam belt. Scientists at the National Root Crops Research Umudike developed the yam minisett technique of seed yam production in 1982 but nearly three decad...

Production of improved water yam (Dioscorea alata) genotypes that are suitable for the preparation of amala (a popular darkish Nigerian food) would likely enhance the economic importance of the crop in Nigeria. Fermented flour (oven dried and sun dried) made from tubers of eight new improved D.al...

The study, between 1999 and 2003, investigated the effect of a 3-year fallow with leguminous cover crops on soil fertility and sweetpotato production in the lowland humid forest zone of south-eastern Nigeria. The experiment was a 2 × 13 factorial in a randomized complete block design with three r...
