Agronomic assessment of 76 accessions of tropical fine stem stylo or "tardio" (Stylosanthes guianensis Sw. var. guianensis) was carried out at the Carimagua Research Station in the eastern plains region of Colombia. Of 27 accessions tested for dry matter yield, CIAT 10136 was the highest yielder ...

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...

The seed yields and limitations to seed production for four tropical grass cultivars were defined via a replicated field experiment conducted over three years at the Cerrados Agricultural Research Centre near Brasilia (latitude 15° 36' S; longitude 47° 42' W) in a tropical savanna region. The fou...

Growth and mineral uptake of twenty-four tropical forage legumes and grasses were compared under glasshouse conditions in a sterile low P oxisol, one part inoculated and the other not inoculated with mycorrhizal fungi. Shoot and root dry weights and total uptake of P, N, K, Ca, and Mg of all the ...

A polyacrylamide gel electrophoresis procedure was developed for discriminating cultivars of the forage legume Pueraria phaseoloides on the basis of the patterns of cotyledon proteins. The genotypic marker proteins were extracted with 5M acetic acid and electrophoresed at pH 3.1 in aluminum lacta...

No Brasil, o potencial para o estabelecimento de uma exploração expecializada em produção de sementes de forrageiras é considerável. Para que estes produtores de sementes obtenham êxito em seu empreendimento é necessário que eles se estabeleçam em regiões ideais para esta atividade agrícola. Nest...
