Most families in the area of Tiahuanaco, Bolivia participate in livestock production, mainly cattle breeding. The primary feed sources for livestock in this area are native grasses, barley, and, to a smaller degree, oats. These grasses have low yield because of climate and soil conditions. This area does not have enough forage, especially during the dry season, and the animals are not regularly fed during the year. Consequently, animal production is low. This research was conducted during 2001 and 2002 at the Bolivian Catholic University campus, Farmer’s Academic Unit of Tiahuanaco, Ingavi Province, La Paz, Bolivia. Study site locations were characterized by clay soils, low fertility, an annual median temperature of 8.35° C, and a mean precipitation of 495.4 mm. Five species of grasses were used: Agropyron trichophorum Link (Pubescent), Dactylis glomerata L. (Dactilo-Orchard), Agropyron cristatum Gaertn (Agropiro), Phleum pratensis L. (Fleo), and Bromus inermis Leysser (Bromo). In order to evaluate agronomic behavior of the forage grasses, the following measurements were collected: plant height, population size, leaf width and length, number of sprouts per plant, soil hedging, and yields of green and dry matter.
