Abaidoo, R.C.Singh, BBNwoke, CPypers, PieterDiels, J.Kolawole, G.O.[Evaluation of shoot and root traits for identifying P-use efficient cowpea genotypes]Evaluation of shoot and root traits for identifying P-use efficient cowpea genotypes

Soybean is a relatively new crop to most African smallholder farming communities. Cultivation is expanding rapidly because of its perceived potential to enhance soil fertility through biological nitrogen fixation and its source as food and cash. High N2, fixation in promiscuous soybean genotypes ...

Abaidoo, R.C.Sanginga, NteranyaOkogun, J.A.Kolawole, G.O.Tossah, B.K.Diels, J.[Genotypic variation of soybean for phosphorus use efficiency and their contribution of N and P to subsequent maize crops in three ecological zones of West Africa]Genotypic variation of soybean for phosphorus use efficiency and their contribution of N and P to subsequent maize crops in three ecological zones of West Africa

A longterm alley cropping trial was undertaken on an eroded Oxic paleustalf in the forest-savanna transition zone of southwestern Nigeria from 1981–1993. Two nitrogen fixing hedgerow species (Gliricidia sepium and Leucaena leucocephala) and two non legume hedgerow species (Alchornea cordifolia an...


Kang, B.T.Caveness, F.E.Tian, G.Kolawole, G.O.[Longterm alley cropping with four hedgerow species on an Alfisol in southwestern Nigeria effect on crop performance, soil chemical properties and nematode population]Longterm alley cropping with four hedgerow species on an Alfisol in southwestern Nigeria effect on crop performance, soil chemical properties and nematode population

A screenhouse experiment was conducted to assess the effects of seed size and phosphorus (P) fertilization on growth of 12 herbaceous and shrub legumes [Arachis hypogaea, Cajanus cajan, Centrosema pascuorum, Centrosema brasilianum, Crotolaria ochroleuca, Glycine max, Lablab purpureus, Mucuna coch...


Kolawole, G.O.Kang, B.T.[Effect of seed size and phosphorus fertilization on growth of selected legumes]Effect of seed size and phosphorus fertilization on growth of selected legumes

The potential of planted leguminous cover crop fallow as an alternative to the natural regrowth fallow for sustaining the productivity of low activity clay (LAC) soils in the tropics as the fallow period shortens was tested at Ibadan in the forest-savanna zone of southwestern Nigeria. The study, ...


Tian, G.Kolawole, G.O.Salako, F.K.Kang, B.[An improved cover cropfallow system for sustainable management of low activity clay soils of the tropics]An improved cover cropfallow system for sustainable management of low activity clay soils of the tropics

The effects of burning, incorporation and surface mulching after one year of natural regrowth (NF) and Pueraria cover crop fallows on soil P fractions and maize and cassava yields were assessed. Data were collected between 1998 and 2000 as part of an on-going long-term fallow management trial est...


Tian, G.Kolawole, G.O.Tijani-Eniola, H.[Phosphorus fractions in fallow systems of West Africa: effect of residue management]Phosphorus fractions in fallow systems of West Africa: effect of residue management

Phosphorus is important for cowpea production in many tropical African soils with inherent low P fertility. Most farmers in Africa, however, do not have access to P fertilizer. Selection of cowpea lines that produce good yield under low soil P or those with high P-use efficiency can be a low inpu...


Kolawole, G.O.Tian, G.Singh, B.B.[Differential response of cowpea lines to application of P fertilizer]Differential response of cowpea lines to application of P fertilizer

Simultaneous intercropping is a crop-management strategy that is applied by the majority of small-scale farmers in the derived savanna of West Africa. Developing improved systems that are close to farmers' practices is likely to lead toadoption. This paper report economic results from a 2year on-...


Manyong, Victor M.Tian, G.Makinde, K.Kolawole, G.O.[Economic evaluation of systems intercropping food crops with leguminous cover crops in the derived savanna of Nigeria]Economic evaluation of systems intercropping food crops with leguminous cover crops in the derived savanna of Nigeria

Legume cover crops are a potential means for overcoming N depletion in the derived savanna of West Africa. A 3-year trial was, therefore, conducted near Ibadan, southwestern Nigeria to measure the N contribution of 13 legume cover crops as compared to urea –N, using a N fertilizer replacement ind...
