Resumo
Soybean cultivation has been one of the main alternatives for the restoration and
renovation of degraded pastures, and soybean rotation with pasture has provided
benefits to both cultures. However, it has been observed that forage in these areas
becomes the main weed species that compete with soybeans, due to the seed bank
formed by previous grazing. Thus, the aim of this study was to evaluate the
emergence and development of soybean seedlings when sown with three different
species of Brachiaria (Brachiaria decumbens, Brachiaria ruziziensis and Brachiaria
humidicola). In soybean seedlings grown with cover crops evaluated the germination
percentage, root length, shoot length, fresh weight and dry weight. The experimental
design was completely randomized with four treatments and four replications. Means
were compared statistically by the Tukey test (p ≤ 5%). Brachiaria species interfered
with the germination and initial development of soybean seedlings. The long
association of soy with Brachiaria species, the densities used did not provide
sufficient competition to cause interference on the parameters evaluated.
