Rusinamhodzi, LeonardCorbeels, MarcZingore, ShamieNyamangara, JusticeGiller, Ken E.[Pushing the envelope? Maize production intensification and the role of cattle manure in recovery of degraded soils in smallholder farming areas of Zimbabwe]Pushing the envelope? Maize production intensification and the role of cattle manure in recovery of degraded soils in smallholder farming areas of Zimbabwe

Soybean yields could benefit from the use of improved varieties, phosphate-fertilizer and rhizobium inoculants. In this study, we evaluated the results of widespread testing of promiscuous soybean varieties with four treatments: no inputs (control); SSP fertilizer (P); inoculants (I) and SSP plus...


Ronner, E.Franke, A.C.Vanlauwe, BernardDianda, M.Edeh, E.Ukem, B.Bala, A.Heerwaarden, Joost vanGiller, Ken E.[Understanding variability in soybean yield and response to P-fertilizer and rhizobium inoculants on farmers' fields in northern Nigeria]Understanding variability in soybean yield and response to P-fertilizer and rhizobium inoculants on farmers' fields in northern Nigeria
Rusinamhodzi, LeonardCorbeels, MarcGiller, Ken E.[Diversity in crop residue management across an intensification gradient in southern Africa: System dynamics and crop productivity]Diversity in crop residue management across an intensification gradient in southern Africa: System dynamics and crop productivity

In communal areas of NE Zimbabwe, feed resources are collectively managed, with herds grazing on grasslands during the rainy season and mainly on crop residues during the dry season, which creates interactions between farmers and competition for organic resources. Addition of crop residues or ani...


Rufino, Mariana C.Dury, J.Tittonell, Pablo A.Wijk, Mark T. vanHerrero, Mario T.Zingore, ShamieMapfumo, PaulGiller, Ken E.[Competing use of organic resources, village-level interactions between farm types and climate variability in a communal area of NE Zimbabwe]Competing use of organic resources, village-level interactions between farm types and climate variability in a communal area of NE Zimbabwe

Oil palm production must increase in Ghana to meet the increasing demand for palm oil and avoid costly imports. Although maximum fruit bunch (FB) yields of >20 t ha−1 yr−1 are achievable, average FB yields in Ghana are only 7 t ha−1 yr−1. Despite the pressing need to increase palm oil production ...


Rhebergen, T.Fairhurst, ThomasWhitbread, Anthony M.Giller, Ken E.Zingore, S.[Yield gap analysis and entry points for improving productivity on large oil palm plantations and smallholder farms in Ghana]Yield gap analysis and entry points for improving productivity on large oil palm plantations and smallholder farms in Ghana

Grain legumes play a key role in smallholder farming systems in sub-Saharan Africa (SSA), in relation to food and nutrition security and income generation. Moreover, because of their N2-fixation capacity, such legumes can also have a positive influence on soil fertility. Notwithstanding many deca...


Vanlauwe, BernardHungria, M.Kanampiu, F.Giller, Ken E.[The role of legumes in the sustainable intensification of African smallholder agriculture: lessons learnt and challenges for the future]The role of legumes in the sustainable intensification of African smallholder agriculture: lessons learnt and challenges for the future

Poor yields of East African highland bananas (Musa spp., AAA-EAHB) on smallholder farms have often been attributed to problems of poor soil fertility. We measured the effects of mineral fertilizers on crop performance at two sites over two to three crop cycles; Kawanda in central Uganda and Ntung...


Nyombi, K.Asten, Piet J.A. vanCorbeels, MarcTaulya, G.Leffelaar, P.A.Giller, Ken E.[Mineral fertilizer response and nutrient use efficiencies of East African highland banana (Musa spp., AAAEAHB, cv. Kisansa)]Mineral fertilizer response and nutrient use efficiencies of East African highland banana (Musa spp., AAAEAHB, cv. Kisansa)
Rurinda, J.Wijk, Mark T. vanMapfumo, PaulDescheemaeker, KatrienSupit, I.Giller, Ken E.[Climate change and maize yield in southern Africa: what can farm management do?]Climate change and maize yield in southern Africa: what can farm management do?

Oil palm, currently the world’s main vegetable oil crop, is characterised by a large productivity and a long life span (≥25 years). Peak oil yields of 12 t ha−1 yr−1 have been achieved in small plantations, and maximum theoretical yields as calculated with simulation models are 18.5 t oil ha−1 yr...

Climbing beans offer potential for sustainable intensification in the East-African highlands, but their introduction requires a major change in the cropping system compared with the commonly grown bush bean. We explored farm-level opportunities, constraints and trade-offs for climbing bean cultiv...
