Asten, Piet J.A. vanGold, C.S.Okech, S.H.O.Gaidashova, S.V.Tushemereirwe, W.K.Waele, D. de[Soil quality problems in East African banana systems and their relation with other yield loss factors]Soil quality problems in East African banana systems and their relation with other yield loss factors

Since plants first colonized land, endophytic bacteria and fungi have been inside them, contributing to their hosts' survival and evolution. Endophyte ecology is an active field of study seeking to understand principles of host strain selection and microbial provenance; although most plants were ...

By altering evapotranspiration and influencing how water is routed and stored in a basin, natural and agrarian ecosystems affect river flow. To quantify the impact of ecosystems on streamflow in two large river basins in Asia and Africa, simple statistical relationships were calculated, enabling ...


Lacombe, GuillaumeMcCartney, Matthew P.[Evaluating the flow regulating effects of ecosystems in the Mekong and Volta river basins]Evaluating the flow regulating effects of ecosystems in the Mekong and Volta river basins

Although there is increasing visibility and international frameworks for soil organic carbon, investment and action at sufficient scales is lagging behind. Practices that retain and increase soil organic carbon are well established but their effect is highly context specific. There is less unders...

The pH dependent cation exchange capacity (CEC) and pH buffering capacity (pH BC) are two crucial properties in soil fertility management of variable charge soils. However, they are rarely measured, since most of the existing methods are cumbersome and time-consuming. We propose a new method, bas...

Cassava is Africa's second most important food source in terms of calories consumed per capita. However, farmers use little or no fertilizer on cassava and scant information is available regarding the cassava yield response to mineral and organic fertilizer inputs in Zambia. This study was undert...


Biratu, G.K.Elias, E.Ntawuruhunga, PheneasSileshi, Gudeta W.[Cassava response to the integrated use of manure and NPK fertilizer in Zambia]Cassava response to the integrated use of manure and NPK fertilizer in Zambia

Reliable information on the persistence of rhizobium in soil in the absence of host between growing periods is important in deciding whether inoculation on the same plot in subsequent seasons is necessary. This study determined the survival of introduced rhizobium strains and predominant factors ...


Ulzen, J.Abaidoo, R.C.Masso, C.Owusu-Ansah, E.D.J.Ewusi-Mensah, N.[Is there a need for Bradyrhizobium yuanmingense and B. japonicum reinoculation in subsequent cropping seasons under smallholder farmers' conditions?]Is there a need for Bradyrhizobium yuanmingense and B. japonicum reinoculation in subsequent cropping seasons under smallholder farmers' conditions?

Cowpea [Vigna unguiculata (L.) Walp.] plays an important role in the livelihoods of the people of sub-Saharan Africa, but phosphorus (P) deficiency in soils is a serious problem that contributes to low productivity. This study was conducted to verify the efficiency of indigenous rock phosphate (R...


Suzuki, K.Fatokun, C.A.Boukar, O.[Responses of cowpea genotypes to indigenous rock phosphate application]Responses of cowpea genotypes to indigenous rock phosphate application

Improving agricultural productivity to keep pace with the fast-growing food demand is a huge challenge for sub-Saharan Africa (SSA). Fertilizer is a powerful productivity-enhancing input; nevertheless, farmers of SSA use only 5–9 kg ha−1 of fertilizer, which is ten times lesser than Latin America...

Improving soil health by utilizing the appropriate tillage, cropping systems and soil management practices is important for enhanced soil quality and agricultural productivity. Of key importance is effect of these factors on the persistence of soil faunal diversity, biomass and their performance ...
