This study was done with the objective of evaluating the agronomic performance of five varieties of forage grasses introduced to the community of Carmen Pampa in the province of Nor Yungas, La Paz from 2005-2006. The average temperature during the study was 11.93ºC and the average precipitation was 801.75 mm. The trial was done with a design of randomized blocks having five species and six repetitions. The species studied were: Panicum virgatum, Sorghastrum nutans, Andropogon gerardii, Tripsacum dactyloides, and Eragrostis curvula. Variables evaluated were: plant height (cm), coverage (%), number of plants, bunches of florets, and dry matter yield (kg/ha). The forage species that grew highest were Eragrostis curvula (55.5 cm) and Panicum virgatum (44.96 cm). Those same species also showed the best performance in regard to coverage with 88% and 33.4%, respectively. Eragrostis curvula had the largest number of plants with an average of 72.5 plants per m2. With regard to bunches of florets, Eragrostis curvula had the most with 31.33 bunches. As for dry matter yield, Eragrostis curvula had the best performance with 5298.5 kg/ha.
