Wyckhuys, Kris A.G.[Phyto-pathogens and Soil Nutrients Shape Biological Control of Invasive Mealybugs in Asia’s Cassava Crops]Phyto-pathogens and Soil Nutrients Shape Biological Control of Invasive Mealybugs in Asia’s Cassava Crops

The moist savannas of West and Central Africa have great potential for maize grain production due to high levels of radiation and reduced incidence of pests and diseases. However, soils in this zone are generally low in organic matter and cation exchange capacity in addition to land use intensifi...


Ajala, S.O.Menkir, A.Kamara, A.Y.Alabi, S.O.Abdulai, M.S.[Breeding strategies to improve maize for adaptation to low soil nitrogen in West and Central Africa]Breeding strategies to improve maize for adaptation to low soil nitrogen in West and Central Africa

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

Kang, B.T.Fox, R.L.[Influence of soil fertility on the protein and sulphur contents on grain legumes]Influence of soil fertility on the protein and sulphur contents on grain legumes

The major thrust of the West and Central Africa Collaborative Maize Research Network (WECAMAN) has been on the development of early and extra-early maize varieties and associated agronomic practices. Adoption of these varieties and, to some extent, the complementary agronomic practices by farmers...


Badu-Apraku, B.Fakorede, M.A.B.Ajala, S.O.[Promoting maize technology transfer in West and Central Africa: a networking approach]Promoting maize technology transfer in West and Central Africa: a networking approach

Mulch applications generally have a large beneficial effect on the productivity of important perennial cash crops in the East African Highlands such as bananas (Musa spp.) and coffee (Coffea spp.), due to the conservation of soil moisture and the improvement of soil fertility. However, the availa...


Asten, Piet J.A. vanTwagirayezu, A.Gaidashova, S.V.[Effect of Guatamala grass (Tripsacum laxum) mulch applications on soil moisture conservation and soil fertility status]Effect of Guatamala grass (Tripsacum laxum) mulch applications on soil moisture conservation and soil fertility status
Martínez, A.León Sarmiento, Luis AlfredoNavas Alvarado, J[Uso potencial de rocas fosfóricas y de rocas fosfóricas parcialmente aciduladas en la agricultura colombiana]Uso potencial de rocas fosfóricas y de rocas fosfóricas parcialmente aciduladas en la agricultura colombiana

Because of their favourable hydrology, the small inland valleys of West Africa offer the possibility of sustainable increases in food crop production. A key component in any sustainable cropping system is the maintenance or restoration of soil fertility. This paper explores avenues for introducin...


Carsky, R.J.Ajayi, E.O.[Fitting soilimproving legumes into inland valley ricebased cropping systems in West Africa]Fitting soilimproving legumes into inland valley ricebased cropping systems in West Africa

On-farm trials were conducted at Kaduna in the northern Guinea savanna of Nigeria in 1996 and 1997. The objective was to investigate the residual effects of Mucuna and cowpea grown during the first 2-3months of the season on subsequent maize yields, to elicit farmers' feedback on these cropping s...


Oyewole, B.Carsky, R.J.Schulz, S.[Onfarm testing of Mucuna and cowpea double cropping with maize in the Guinea savanna of Nigeria]Onfarm testing of Mucuna and cowpea double cropping with maize in the Guinea savanna of Nigeria

In order to promote the identification of herbaceous legumes that may contribute to weed control, soil fertility, crop production, and livestock enterprises, as a means of encouraging sustainable agricultural practices amongst resource-poor farmers, an evaluation method using a simple sampling ap...
