The present study had the objective to evaluate the establishment of Italian Rye grass (Lolium multiflorum) under five densities of seeding (15, 30, 45, 60 and 75 kg of seed/ha) into degraded pastures invaded by kikuyu (Pennisetum clandestinum), as an alternative to rotations with agricultural cultivations. Each density was mixed with 3.0 kg/ ha of Lucerne seed (Ranger variety). The study was carried out at the “El Mantaro-IVITA” Research Station from March till July 2002. A land with degraded pasture that was grazed for seven years was mechanically prepared and the Italian Rye grass seed was vollied by hand. The fertilization was carried out with 60-20-0 of N-P2O5-K2O kg/ha thirty days after seedding. The statistical analysis was done using the randomized complete block design with three repetitions. The botanical composition before the first grazing (120 days after seeding) showed a significant increase (p<0.05) of the Italian Rye grass proportion (21.3 to 82.9% with the seeding density of 15 and 75 kg, respectively). The biomass production of Italian Rye grass significantly increased (p<0.05) with the increase of seeding density. It was concluded that the Italian Rye grass is better established into degraded areas invaded by kikuyu, when the seeding density was >30kg/ha.
