During two years, a study was conducted to assess the impact of the introduction of white clover in natural prairies dominated by Festuca dolichophylla. The study area was located at 4 500 m.a.s.l. in the region of Pasco; Ayaracra sector belonging to the Puna ecoregion. The study design was a 2x2 factorial in blocks with two factors of phosphorus 0 to 80 kg / ha and two distances between sowing seeds gaps (0.5 v / s 1.0m). The parameters evaluated were coverage, density, vigor, productivity, degree of nodulation and nitrogen content the plant and soil. The results revealed that phosphorus improved (P <0.05) the height, yield and vigor of Fedu and that there was no effect of distancing in the parameters evaluated. When the effect of phosphorus and distancing the behavior clover was evaluated it was found that the phosphorus improved the degree of nodulamiento (P <0.05), but there was no significant effect on the nitrogen content in the key plant and in the soil, despite there was a clear trend toward improvement. Interactions between phosphorus and nitrogen. It is recommended to evaluate the persistence and adaptive capacity of Trifoliun repens to different management conditions and environmental stress to determine the optimal environments where it can apply this strategy of improving prairies.
