Exotic legumes (Calopogonium mucunoides, Centrosema pubescens, Pueraria phaseoloides, Macroptilium atropurpureum) and indigenous legumes (Desmodium heterophyllum, Mimosa pudica, Vigna luteola) were compared for dry matter (DM) and crude protein (CP) production, nitrogen fixation and nitrogen tran...
The productivity and nutritive value of Chamaecrista rotundifolia cv. Wynn, Centrosema pascuorum cv. Cavalcade, Stylosanthes guianensis cv. Pucallpa and S. hamata cv. Verano as affected by single superphosphate fertilisation (SSP) and weed control were measured during the dry season in subhumid N...
A small-plot grazing trial was conducted to assess selection by oesophageal-fistulated steers of 5 shrubby legumes adapted to acid, low-fertility soils (Centrosema arenarium, Desmodium strigillosum, D. velutinum, Flemingia macrophylla, and Tadehagi triquetrum) and the herbaceous Centrosema acutif...
The yield attributes of 18 accessions of Centrosema, comprising the species, C. macrocarpum, C. brasilianum, Centrosema sp. nov. were compared in two experiments under a cutting regime. Small, grazed swards of various Centrosema spp. sown with Andropogon gayanus in mixture were also studied, with...
A survey of three regions of Colombia revealed a total of 31 species of plant-parasitic nematodes associated with tropical pasture legumes and grasses. Seventeen of these nematode species had not been recorded previously in Colombia. There also are 120 newly reported associations of plant-parasit...
Three phases of Rhizobium inoculation trials were carried out as part of a programme to select forage legume germplasm adapted to acid, infertile Oxisols of tropical America. Firstly, a range of tropical forage legumes were evaluated for their response to N fertilization or inoculation with strai...
