Rusinamhodzi, LeonardWijk, Mark T. vanCorbeels, MarcRufino, Mariana C.Giller, Ken E.[Maize crop residue uses and trade-offs on smallholder crop-livestock farms in Zimbabwe: economic implications of intensification]Maize crop residue uses and trade-offs on smallholder crop-livestock farms in Zimbabwe: economic implications of intensification

Soil nutrient constraints coupled with erratic rainfall have led to poor crop yields and occasionally to crop failure in sole cropping in the Guinea savanna of West Africa. We explored different maize-grain legume diversification and intensification options that can contribute to mitigating risks...


Kermah, M.Franke, A.C.Ahiabor, B.D.K.Adjei-Nsiah, SamuelAbaidoo, R.C.Giller, Ken E.[Legume-maize rotation or relay? Options for ecological intensification of smallholder farms in the Guinea Savanna of northern Ghana]Legume-maize rotation or relay? Options for ecological intensification of smallholder farms in the Guinea Savanna of northern Ghana
Hengsdijk, H.Franke, A.C.Wijk, Mark T. vanGiller, Ken E.[How small is beautiful? Food self-sufficiency and land gap analysis of smallholders in humid and semi-arid sub Saharan Africa]How small is beautiful? Food self-sufficiency and land gap analysis of smallholders in humid and semi-arid sub Saharan Africa

N2 fixation in lines of Phaseolus vulgaris was measured by 15N-isotope dilution to determine whether a programme of crossing and recurrent selection had resulted in enhanced nitrogen fixation. In field experiments on an isohyperthermic Aquic Hapludoll soil the amount of N2 fixed by the different ...

Karanja, S.Herrero, Mario T.Ridder, N.A. deBaijukya, Frederick P.Mwale, M.Kaizzi, C.Mapfumo, PaulWatat, C.Issaka, R.Sanogo, O.Kungu, J.Mugendi, D.Quirós, CarlosTittonell, Pablo A.González Estrada, E.Giller, Ken E.[Income, food security, nutrients and labour: a comparison of key aspects of African smallholder farming systems using IMPACT]Income, food security, nutrients and labour: a comparison of key aspects of African smallholder farming systems using IMPACT

In African smallholder agriculture, improved farm-scale understanding of the interaction between the household, crops, soils and livestock is required to develop appropriate strategies for improving productivity. A combination of models was used to analyse land use and labour allocation strategie...


Zingore, ShamieGonzález Estrada, E.Delve, Robert J.Herrero, Mario T.Dimes, John P.Giller, Ken E.[An integrated evaluation of strategies for enhancing productivity and profitability of resource-constrained smallholder farms in Zimbabwe]An integrated evaluation of strategies for enhancing productivity and profitability of resource-constrained smallholder farms in Zimbabwe

The application of nitrogen in a soil under agricultural production is subject to several pathways including de-nitrification, leaching and recovery by an annual crop. This is as well greatly influenced by the management practices, nitrogen source and soil conditions. The main objective of this s...


Kimetu, J.M.Mugendi, DNBationo, B. AndréPalm, C.A.Mutuo, PKKihara, JobNandwa, SMGiller, Ken E.[Partial balance of nitrogen in a maize cropping systems in humic nitisol of Central Kenya]Partial balance of nitrogen in a maize cropping systems in humic nitisol of Central Kenya

Seed analysis can indicate differences in micronutrient availability between soils. Comparison of Phaseolus vulgaris L. with published analytical data indicated that the micronutrients most limiting for N2-fixation and growth in parts of East and soLithem Africa were Mo and Cu. Significant differ...


Brodrick, SJAmijee, FKipe-Nolt, Judith A.Giller, Ken E.[Seed analysis as a means of identifying micronutrient deficiencies of Phaseolus vulgaris L. in the tropics]Seed analysis as a means of identifying micronutrient deficiencies of Phaseolus vulgaris L. in the tropics

Intensification of smallholder agriculture in sub-Saharan Africa is necessary to address rural poverty and natural resource degradation. Integrated soil fertility management (ISFM) is a means to enhance crop productivity while maximizing the agronomic efficiency (AE) of applied inputs, and can th...
