Poor drainage is found on about 11.3% of agricultural land in Latin America where physiography promotes flooding, high groundwater tables, or stagnant surface water (waterlogging). Waterlogging drastically reduces oxygen diffusion into the soil causing hypoxia which is the main limitation that re...

We conducted an experiment to determine the effects of concentration and astringency of extractable and bound condensed tannins (CT) in tropical legumes on intake, digestibility, and nitrogen (N) utilization by sheep. The test legumes (Desmodium ovalifolium and Flemingia macrophylla) had similar ...

A series of feeding trials with sheep were carried out at the Centro Internacional de Agricultura Tropical in Colombia to assess the effect of wilting and drying on intake rate and acceptability of the shrub legume Cratylia argentea (Desvaux) O. Kuntze. In the first 2 experiments, intake rate was...

Research aimed at developing various Stylosanthes species as forage crops in South America began with the collection of Brazilian germplasm in the 1960s. These efforts have intensified greatly in the past 25 years with the participation of a number of local, national and international institution...
