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 ...

The Yam Improvement for Income and Food Security in West Africa (YIIFSWA) project was initiated to assess and understand the yam-based systems in order to identify the opportunities of interventions that could potentially help to increase productivity in the region. The project consists of two ph...

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 ...

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 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...
