Description
The well-drained isohyperthermic savannas occupy an area of 98 million hectares, and are distributed in Colombia, Venezuela, northern Brazil, and Guyana. This extensive region of tropical America is characterized by a total wet season potential evapotranspiration of 901 to 1060 mn, an average monthly temperature in the wet season above 23.5 °C, and a wet season of six to eight months. The soils are Oxisols of low fertility and the predominant production system is extensive cattle ranching on native pastures of low nutritive value (Cochrane et al., 1985). The Tropical Pastures Program of CIAT began a series of regional trials in the savannas of Colombia (Eastern Plains) in 1980, to identify iaroductive forages adapted to the environmental conditions in this ecosystem. This article present results obtained between 1980 and 1987 from adaptation trials at eight experimental sites.
