Journal Article 2007

Autor: Ojiem, JO Vanlauwe, Bernard Ridder, N.A. de Giller, Ken E.

Nitrogen (N) deficiency is a major constraint to the productivity of the African smallholder farming systems. Grain, green manure and forage legumes have the potential to improve the soil N fertility of smallholder farming systems through biological N2-fixation. The N2-fixation of bean (Phaseolus...

Nitrogen fixation in nine common bean (Phaseolus vulgaris L.) lines was estimated using the 15N isotope dilution method at two locations in two seasons. In the first season at one location no N2 fixation was detected while in the second season up to 51 kg N ha?1 were estimated. There were signifi...

The success of scaling out depends on a clear understanding of the factors that affect adoption of grain legumes and account for the dynamism of those factors across heterogeneous contexts of sub-Saharan Africa. We reviewed literature on adoption of grain legumes and other technologies in sub-Sah...

A survey of selected fields in bean growing regions of Tanzania and a more detailed survey of bean fields in the Lushoto area of northern Tanzania were carried out to establish soil properties limiting the extent of root nodulation of Phaseolus vulgaris L. Soil samples were collected and soil pH,...

Journal Article 1993

Autor: Kipe-Nolt, Judith A. Giller, Ken E.

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 ...

Climbing beans offer potential for sustainable intensification of agriculture, but their cultivation constitutes a relatively complex technology consisting of multiple components or practices. We studied uptake of improved climbing bean production practices (improved variety, input use and manage...
