SANCHEZ, Tania; LAMELA, L    LOPEZ, O. Characterization of the plant community in an association of improved grasses and Leucaena leucocephala cv.: Cunningham. []. , 30, 4, pp. 0-0. ISSN 0864-0394.

In a dairy of the Genetic Enterprise of Matanzas, a work was carried out for five years, with the objective of characterizing the performance of the plant community in an association of improved grasses and Leucaena leucocephala cv Cunningham under commercial conditions. The botanical composition of the pastureland, tree density, dry matter availability and DM, CP, Ca and P contents of the species present in the system were determined. The botanical composition of the pastureland was characterized by a percentage of improved pastures higher than 50%, with predominance of Cynodon nlemfuensis cv. Jamaicano and Panicum maximum cv. Likoni; while leucaena maintained plant density, as an adaptation to the conditions of the system. The total dry matter availability was higher than 3 t/ha/rotation during the experimental stage. It is concluded that in the association of improved grasses and L. leucocephala cv. Cunningham there was high dry matter availability and persistence of the grassland during the five years of evaluation, with values of CP in the improved grasses of 9,6-9,8% and in leucaena of 25%, applying neither irrigation nor chemical fertilizers, which allowed to attenuate the differences between the rainy and dry seasons.
