Effect of sowing depth and soil cover on Paspalum virgatum L. seedling emergence

Paspalum virgatum L. is a grass weed common in pasture and has difficult control, mainly due to its similarity forage, found areas of degraded pastures the state Mato Grosso. The objective this work was evaluate seed germination seedling emergence razor-blade (P. L.) when exposed different sowing depths. Two independent experiments were carried out, one using straw from Brachiaria brizantha cv. Marandu (Experiment I) another Panicum maximum Mombasa II). treatments for both organized 7x2 factorial scheme, considering seven depth levels (0, 1, 2, 3, 4, 5, 10 cm). bottom pots sealed with filter paper gauze. seedlings recorded daily until 28 days after sowing. data obtained submitted analysis variance. For experiment I, there significant effect on soil cover factor relation %E IVE, where use more efficient. II, no IVE. greater depth, lower seedlings.
