En los dos primeros trabajos (la y lb), se evaluó la interacción entre cepas seleccionadas de Rhizobium (apropiadas para la leguminosa forrajera tropical Centrosema macrocarpum) y especies (Entrophospora colombiana, Acaulospora longula, Glomus manihotis) de micorriza vesiculo arbuscular (MVA), en...

En el invernadero se evaluó la efectividad de las cepas preseleccionadas de B. japonicum (CIAT 199,209,3778,3874 y 3876) de la recomendada (CIAT51) y una de Rhizobium spp (CIAT 3779). En el suelo Fluventic Haplustoll, de reacción casi neutra, se presentó respuesta altamente significativa a la ino...

This study examines the potential, magnitude, and causes of enhanced biological N2 fixation (BNF) by common beans (Phaseolus vulgaris L.) through bio-char additions (charcoal, biomass-derived black carbon). Bio-char was added at 0, 30, 60, and 90 g kg?1 soil, and BNF was determined using the isot...

Populations of Legume Nodulating Bacteria (LNB) were assessed under glasshouse conditions in soils collected from selected landuse systems in Taita Taveta district, Kenya. The populations were estimated by the most-probable-number (MPN) plant infection technique using Macroptilium atropurpureum (...

Ten isolates of Bradyrhizobium spp. which form two colony types were studied; the isolates originated from a range of legume species. The two colony types differed in the amount of gum formed or size or both, depending on the strain. Whole 7-day-old colonies of each type were subcultured to deter...

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...

At the Colombian coffee growing area, between 1,000 and 2,000m elevation, experiments were carried out under field conditions on steep slopes at Romelia (2,500 mm rainfall and a Dystrandept type of soil), and at Supía (1,708 mm rainfall and a Eutrandept type of soil). The legumes (Centrosema macr...
