Conference Paper 1998

The effects of feed nitrogen and polyphenol levels on the fate of ingested nitrogen in steers and their implications for nitrogen cycling in mixed farming systems

Autor: Delve, Robert J. Tanner, J.C. Kimani, S. Giller, Ken E. Cadisch, Georg Thorne, Peter J.

Due to inadequate feed supplies for livestock production, farmers throughout the tropics and sub-tropics are being encouraged to supplement low quality basal diets with leguminous forage and concentrates. The varying quality (e.g. nitrogen, lignin and polyphenol content) of these diets will influ...

Effect of intercropping with herbaceous legumes on the yield and quality of Napier grass in the central highlands of Kenya

Autor: Mwangi, D.M. Giller, Ken E. Thorpe, W.R. Thomas, D.

Dairy production in an important enterprise for many smallholders in the East African highlands, where population pressure is high and inheritance traditionally leads to the subdivision of land holdings. As a result, farm sizes are decreasing such that in Kiambu District, central Kenya, they aver...

Understanding variability in soybean yield and response to P-fertilizer and rhizobium inoculants on farmers' fields in northern Nigeria

Autor: Ronner, E. Franke, A.C. Vanlauwe, Bernard Dianda, M. Edeh, E. Ukem, B. Bala, A. Heerwaarden, Joost van Giller, Ken E.

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...

Competing use of organic resources, village-level interactions between farm types and climate variability in a communal area of NE Zimbabwe

Autor: Rufino, Mariana C. Dury, J. Tittonell, Pablo A. Wijk, Mark T. van Herrero, Mario T. Zingore, Shamie Mapfumo, Paul Giller, Ken E.

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...

Yield gap analysis and entry points for improving productivity on large oil palm plantations and smallholder farms in Ghana

Autor: Rhebergen, T. Fairhurst, Thomas Whitbread, Anthony M. Giller, Ken E. Zingore, S.

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 ...

The role of legumes in the sustainable intensification of African smallholder agriculture: lessons learnt and challenges for the future

Autor: Vanlauwe, Bernard Hungria, M. Kanampiu, F. Giller, Ken E.

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...

Mineral fertilizer response and nutrient use efficiencies of East African highland banana (Musa spp., AAAEAHB, cv. Kisansa)

Autor: Nyombi, K. Asten, Piet J.A. van Corbeels, Marc Taulya, G. Leffelaar, P.A. Giller, Ken E.

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...
