Introduction of Forage Legumes into Pastures of Three Different Grasses

It was evaluated the introduction of a mixture of calopo, galaxia, perennial soybean, guata and stylo broadcsted into marandu, setaria and tanzania half-plots already established in three cafeterias, each one located inside a paddock of each grass. The legumes were seeded in the end of the Spring (12/07/98), after the plots had been cut down and fertilized. The cafeterias were grazed intermittently by buffaloes maintained in the three paddocks. The occurrence of the five legume plants was avaluated by countings (#/m2) effected in the middle of Autumn, Winter and Spring of 1999 and Summer of 2000. Along with this last counting it was evaluated the forage remained after grazing and its N%. Marandu-grass presented the higher amount of forage remained after grazing but the lower presence of legumes along all countings. The contrary happened with Tanzania-grass. Significantly higher N% was found in the mixed grass half-plots compared with them without legumes.
