Twenty Mimosa-nodulating bacterial strains from Brazil and Venezuela, together with eight reference Mimosa-nodulating rhizobial strains and two other ?-rhizobial strains, were examined by amplified rRNA gene restriction analysis. They fell into 16 patterns and formed a single cluster together wit...

Rust caused by Puccinia stylosanthis is reported for the first time on native populations of Stylosanthes aurea and S. guianensis var. pauciflora in the vicinity of Diamantina, Minas Gerais, Brazil. Although not common in May 1983, rust severely affected 50% of S. aurea and moderately affected mo...
The effects of size of terminal stem cuttings (2-, 3-, or 4-leaf) and of auxin treatment on percent rooting, root number and root length of six Stylosanthes guianensis accessions were evaluated in a single, factorial experiment.
Overall, 66% of cuttings rooted within ten days. Accessions differ...
The detection of the root-knot nematode, Meloidogyne javanica, as a pathogen of Desmodium spp. in Colombia, is the first reported case in South Aemerica. In the field, promising pasture legumes D. gyroides, D. heterocarpon and D. ovalifolium were severely damaged, while adjacent stands of Centros...

In recent years, increasing numbers of pathogens and pests have been reported from major centres of tropical pasture research. Damage is often severe and controls are needed. Diseases and pests may be controlled chemically, biologically, culturally and genetically. In pasture plants genetical res...

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...

The seed yields and limitations to yield for nine pasture legumes in a tropical savanna region were defined in a 3-year field experiment at the Cerrodos Agricultural Research Centre near Brasilia (15°36' S, 47° 42' W). Assessment was based on flowering times, incidence of diseases and pests, yiel...
