ABSTRACT: This research aimed at investigating which sowing method is more suitable for the deployment of Urochloa ruziziensis to suppress the weed community in no-tillage. The design was a randomized block ones, with a 3 x 2 factorial design, in which the first factor was composed of three sowing methods (broadcast, broadcast with incorporation or line sowing) and factor B consisted in the application and non-application of the herbicide 2,4-D. On day 30 and 60 after sowing (DAS), the relative importance of the present plant species was determined. On day 120 and 180 DAS, the accumulation of biomass and the plant cover percentage on the soil provided by the cover crop and weed species were determined. Moreover, on day 180 DAS, the density of the existing... |

ABSTRACT: Native species seedling growth may be affected by allelopathic substances released by invasive forage species, mainly in natural regrowth areas. Thus, this research aimed to evaluate the growth characteristics of pequi trees influenced by concentrations of plant residues of different forage species (Urochloa decumbens, Melinis minutiflora and Paspalum notatum). A randomized block experimental design was arranged in a factorial 3 x 4 + 1, with four replications. Treatments consisted of incorporating plant shoot residues of three forage species to pequi seedling substrate (soil + fertilizer) at four concentrations (1%, 2%, 3%, and 4% mass/mass), plus pequi seedlings grown in a residue-free substrate (control). Pequi plant height, stem diameter, and... |
