Abstract

Practices that facility the crop establishment are important in weed management, consequently reducing herbicide use. A small time among plant cover desiccation and sowing maize is one of the management practices that can reduce weed infestation due to weed establishment retardation. The aim of this work was to evaluate the effect of the cover crop desiccation time in relation to the maize sowing on the weed infestation and maize yield. An experiment was carried out in Canoinhas, SC, Brazil in the season 2004/05. Ryegrass in a single crop and an intercropping system (ryegrass + black oat + rye + common vetch + oilseed radish) were desiccated in five times: 30, 20, 10, 5 e 1 day before the maize sowing, in a factorial scheme 2 x 5. The cover crop management near to the maize sowing reduced the density and mass accumulation of weeds and improved the maize grain yield.
