The agronomic performance of seven accessios of Arachis pintoi was evaluated between Jauary 1994 and November 1996, on a humic gley Inceptisol. The trial was conducted at the Brasilia Faculty of Agriculture (1500 mm rainfall; 1000 m.a.s.l.; 15o 35' S and 47o 42'W), Planaltina, DF, Brazil. Soil was prepared mechanically for planting, but no fertilizers were applied, nor herbicides for weed control. The treatments consisted of seven accession of A. pintoi that were pre selected at the Cerrados Agricultural Research Center (CPAC) of EMBRAPA. These accessions belonged to a collection of 80 accessions, obtained during expeditons conducted under the coordination of the National Center of Genetic Resources and Biotechnology (CENARGEN), also of EMBRAPA. The germplasm was planted in January 1994 and evaluated until November 1996. Vegetative material was used as planting material for both the legume and the grass Paspalum maritimum BRA-000078. After 60 days of rooting, the A. pintoi plantlets were transplanted at distances of 0.7 m between rows and 0.5 m between plants in 20-m2 plots. The grass was planted between the rows of legume. A completely randomized design was used, with three replications per treatment. The associations of the grass with A. pintoi accessions BRA-013251, BRA-015121, BRA-031135, and BRA-031143 were relatively stable over time. The accessions A. pintoi BRA-030368 and BRA-031542 diminished in the asscociation: after 2 years of cuttings and consecutive grazings, they represented barely 5% of the botanical composition. At the end of the second year, A. pintoi BRA-031828 was the only accession to comprise 60% of the associated pasture, showing good vigor and excellent plant health. Paspalum maritimum BRA-000078 showed high branching ability and stem growth, reaching an average lenght of 703 +- 308 cm per plant and a daily growth rate of 6.8 +- 3.0 cm, between 0 and 104 days after planting. These results highlight the potential of this grass for use in degraded areas; for example, to control erosion on slopes and combat weeds.
