The objective of this research was to evaluate the seed longevity of Eragrostis plana Nees buried at different soil depths, in a natural-grassland area in the Pampa biome (46 m altitude, 30º05´S and 51º40´W) of Rio Grande do Sul State, Brazil. The experimental design was a split-plot type in complete blocks with two factors: seeds buried at five different depth levels (soil surface and 2.5, 5, 10 and 20 cm) and seven exhumation dates. The blocks were allocated in natural […]

The objective of this study was to control biological invasion by Eragrostis plana Nees (South African lovegrass) on a roadside by introducing competitor grasses associated with soil management and fertilization practices. The experimental design was a complete randomized block with split-plots parcels and three replications. In the parcels, it was evaluated two practices of soil treatments: subsoil tillage plus disc harrow tillage and application of limestone and phosphorous; and only subsoil tillage and, in the split-plots, the following grass species: […]

This work was carried out with the objective of evaluating the effect of the bovine digestion process on the germination capacity of the capim-annoni-2 (Eragrostisplana Ness) seeds recovered in feces. The seeds (6 g, 27,273 seeds) were placed in a ruminal ventral sack of eight fistulated steers kept in pen trial. Forthy-three percent of the offered seeds were recovered in the feces. Seeds recovered in the first three days corresponded to 97.2% of the offered seeds. Only 7.2% of the […]
