| Sumario: | Soil and crop management can affect the weed population in corn. The experiment was carried out to evaluate the
effect of cultural and chemical management practices on weed infestation and corn yield. The experiment was carried out in
Papanduva, SC, Brazil. The experimental design was a randomized complete blocks with three replications in a split-plot
arrangement. In plots were evaluated two cultural weed management systems: S1 (multicropping of winter cover crops, corn
seeds with high weight and narrow row of 0.45 m) and S2 (winter fallow, corn seeds with low weight and narrow row of 0.90
m). In subplots were evaluated four weed control strategies (no-control, atrazine, atrazine + mesotrione and weeding). The
parameters evaluated were the straw quantity, residue decomposition, weed plant density and shoot dry mass and corn
performance. The use of cultural weed management practices reduced the weed infestation on corn and improved the crop
yield. The association of atrazine + mesotrione herbicides showed more efficient weed control than atrazine. |
