The aim of the Integrated Cassava Project (ICP) of the International Institute of Tropical Agriculture was to pre-emptively manage the cassava mosaic disease (CMD) to avert an imminent and increasing possible threat of the Ugandan strain of the CMD virus of the pathogen from doing damage to the N...


Dixon, A.Akoroda, M.O.Okechukwu, R.U.Ogbe, F.Ilona, P.Sanni, L.O.Ezedinma, C.Lemchi, J.Ssemakula, G.N.Yomeni, M.Okoro, E.Tarawali, G.[Fast track participatory approach to release of elite cassava genotypes for various uses in Nigerias cassava economy]Fast track participatory approach to release of elite cassava genotypes for various uses in Nigerias cassava economy

Cassava is a dominant component in crop mixtures in South-Eastern Nigeria. It is a preferred food security crop among smallholder farmers, because it can tolerate drought, low soil fertility and its production requires minimum external inputs. Various constraints have been shown to affect the wid...


Udensi, U.E.Tarawali, G.Favour, E.U.Asumugha, G.N.Ezedinma, C.Okoye, B.C.Okarter, C.Ilona, P.Okechukwu, R.U.Dixon, A.[Adoption of selected improved cassava varieties among smallholder farmers in SouthEastern Nigeria]Adoption of selected improved cassava varieties among smallholder farmers in SouthEastern Nigeria

The results are presented of a project to promote integrated Striga control (ISC) technologies to farmers in the Guinea savanna of northern Nigeria. Extension agents used a participatory research and extension approach (PREA) to encourage farmers to test and adopt ISC technologies. Over a 2-year ...


Franke, A.Ellis-Jones, J.Tarawali, G.Schulz, S.Hussaini, M.A.Kureh, I.White, R.Douthwaite, BoruOyewole, B.Olanrewaju, A.S.[Evaluating and scalingup integrated Striga hermonthica control technologies among farmers in northern Nigeria]Evaluating and scalingup integrated Striga hermonthica control technologies among farmers in northern Nigeria

Speargrass is a serious weed in many farming systems of West Africa. Participatory research and extension approaches were used to promote farmer testing of alternative speargrass management options in yam, cassava and soybean in Nigeria. Treatments were paired plots with a farmers' control and at...


Chikoye, D.Ellis-Jones, J.Avav, T.Kormawa, P.M.Udensi, U.E.Tarawali, G.Nielsen, O.K.[Promoting integrated management practices for speargrass (Imperata cylindrica (L) Raeusch.) in soybean, cassava and yam in Nigeria]Promoting integrated management practices for speargrass (Imperata cylindrica (L) Raeusch.) in soybean, cassava and yam in Nigeria

Traditional shifting cultivation systems can no longer be sustained in West Africa because of rapid increases in human and livestock populations. Short-duration, improved fallows are among the alternative land-management strategies that have evolved. This paper reviews how velvetbean or mucuna (M...

Studies of potassium (K) fixation in the soil were conducted by evaluating the effect of applied K on the extractability of K with time. A series of five K-sorption treatment solutions, 0.11, 0.22, 0.45, 0.90, and 1.80 cmol/kg were prepared and applied as potassium chloride (KC1) to three sets of...

The parasitic angiosperms, Striga hermonthica and S. gesnerioides, obligate root parasites endemic in sub-Saharan Africa, constitute severe constraints to cereal and legume production in West and Central Africa. Over the years, a range of effective component technologies has been identified for S...

Infestation of cereals and cowpeas by Striga species constitute a major constraint to increased crop pro-ductivity in the savannas of northern Nigeria. Field surveys were undertaken in Jigawa State, Nigeria in2012 to assess (i) the level and extent of Strgia infestation of cereal and cowpea field...

An advanced time series econometric technique was used to study the interaction between the prices of fermented flour, a popular cassava-based food product also called lafun, in typical urban-demand and ruralsupply markets in Nigeria. The price data cover 95 weeks from week 37 of 2004 to week 28 ...
