| ABSTRACT: Sunflower is an important crop for Integrated Crop-livestock Systems (ILCS), and one of the main management difficulties identified in this crop is weed control, especially under no-till conditions when chemical weed control is not allowed. Therefore, the aim of this research was to evaluate the effect of greater sunflower population density on weed control, and its impact on sunflower yield, in an ILCS with eucalyptus in an Environmental Protection Area. Two population densities were tested (45 and 90 thousand pl. ha-1) in two crop systems (sunflower monoculture and sunflower-eucalyptus integration). An additional treatment was provided in the sunflower-eucalyptus integration, and 5 positions (2,4; 4,8; 7,2; 9,6; and 12 m) between the tree rows... |

| ABSTRACT: Trees in integrated crop-livestock systems can reduce infestation and dispersion of weeds because of a negative interference promoted by competition for light, water and nutrients. The objective of this study was to evaluate the infestation and dispersion of sticky nightshade (Solanum sisymbriifolium) in soybean in different positions between eucalyptus (Eucalyptus dunnii) double rows [20 m x (4 m x 3 m)] in an integrated crop-livestock system at Subtropical Brazil. The experiment was conducted in a randomized block design, with nine replications, and five equidistant positions between double rows (n=45) as treatments. Sticky nightshade was evaluated for infestation through biomass, plant density (reproductive and vegetative plants), and for... |
