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 ...

A survey was conducted in major yam cultivation zones in Côte d’Ivoire in 2009 to determine the incidence, severity of viral diseases, and viruses associated with the infected plants. Incidence and severity of the viral diseases were estimated based on symptoms. Enzyme-linked immunosorbent assay ...

Yam production is constrained by the limited availability and high cost of quality seed due to its slow vegetative propagation ratio. Micropropagation using nodal and meristem explants have been used to produce clean plantlets, with a 1:4 multiplication ratio for nodal explants and 1:1 ratio for ...

The associations between the production and some of the variously-debated factors that have the tendency to influence it, including cultivated land area, yield, and climatic conditions, were investigated for yams (Discora Roundata), a leading tuber crop in Nigeria. Secondary data collected from t...

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...

Tuber dormancy is of major importance in yam production, but the lack of a method to consistently break dormancy restricts the rate at which new clones can be multiplied to release to farmers. Much of the work on yam tuber dormancy was small scale, using only one or two clones and a few tubers. O...

Yams (Dioscorea spp.) constitute an important starchy staple in sub-Saharan Africa (SSA) where food security for a growing population is a critical issue. Mixed cropping in yam based systems is the norm in the region and productivity of yams in these systems is below potential. It is concluded th...
