Phosphorus release from decomposing leaf biomass of Calliandra calothyrsus Meissner, Tithonia diversifolia Hensley A.Gray and Tephrosia vogelii Hook.f. agroforestry species applied alone or combined with triple super phosphate (TSP) was studied at World Agroforestry Centre (ICRAF) laboratory for ...


Mukuralinda, A.Tenywa, J.S.Verchot, Louis V.Obua, J.Namirembe, S.[Decomposition and phosphorus release of agroforestry shrub residues and the effect on maize yield in acidic soils of Rubona, southern Rwanda]Decomposition and phosphorus release of agroforestry shrub residues and the effect on maize yield in acidic soils of Rubona, southern Rwanda

Green manure of multipurpose trees is known to be a good source of nutrients to crop. However, most agroforestry species do not have adequate phosphorus in their leaves. Supplementing green manure with moderate dose of P is a beneficial strategy to improve food security in Rwanda. This study exam...


Mukuralinda, A.Tenywa, J.S.Verchot, Louis V.Obua, J.Nabahungu, N.L.Chianu, J.N.[Phosphorus uptake and maize response to organic and inorganic fertilizer inputs in Rubona, Southern Province of Rwanda]Phosphorus uptake and maize response to organic and inorganic fertilizer inputs in Rubona, Southern Province of Rwanda

Dairy production is a major contributor towards national economies and household food security and incomes in sub-Saharan Africa (SSA). Milk production in the region is estimated at 1.27 million metric tonnes year-1. However, this level of milk production is inadequate for the existing human popu...


Mubiru, S.L.Tenywa, J.S.Halberg, N.Romney, D.L.Nanyeenya, W.Baltenweck, IsabelleStaal, Steven J.[Categorisation of dairy production systems: A strategy for targeting meaningful development of the systems in Uganda]Categorisation of dairy production systems: A strategy for targeting meaningful development of the systems in Uganda

Knowledge of status of nutrient management in agricultural production systems is critical in the development of sustainable improvement options; however, in mixed dairy-crop systems in Uganda, which are gaining prevalence, the status of nutrient management is unclear. Nitrogen (N) being one of th...


Mubiru, L.S.Romney, D.L.Halberg, N.Tenywa, J.S.[Development of nutrient management strategies based on mapping of nitrogen flows and balances in dairy production systems in Uganda]Development of nutrient management strategies based on mapping of nitrogen flows and balances in dairy production systems in Uganda

Soil Organic Carbon (SOC) is a major indicator of soil fertility in the tropics and underlies variability in crop response to mineral fertilizers. Critical SOC concentrations that interact positively with N fertilizer for optimal crop yield are less understood. A study was conducted on a Ferralso...


Musinguzi, P.Ebanyat, PeterTenywa, J.S.Basamba, T.A.Tenywa, M.M.Mubiru, D.N.[Critical soil organic carbon range for optimal crop response to mineral fertiliser nitrogen on a ferralsol.]Critical soil organic carbon range for optimal crop response to mineral fertiliser nitrogen on a ferralsol.

In 1996, Cassava Mosaic Disease in Western Kenya depressed productivity and de-stabilized markets. The study assesses the effectiveness of breeding and disseminating CMD-resistant varieties in western Kenya by determining the extent of adoption and impact on farmers' income of the new varieties v...


Abele, S.Twine, Edgar E.Ntawuruhunga, PheneasTenywa, J.S.Nampala, P.Okori, P.Kyamuhangire, W.Adipala, E.Tusiome, G.Odendo, M.Obiero, H.Odenya, J.[Effectiveness of breeding and disseminating CMDresistant cassava varieties in western Kenya]Effectiveness of breeding and disseminating CMDresistant cassava varieties in western Kenya

We propose a novel indicator measuring one dimension of the sustainability of an entity in modern societies: Nitrogen-neutrality. N-neutrality strives to offset Nr releases an entity exerts on the environment from the release of reactive nitrogen (Nr) to the environment by reducing it and by offs...
