| ABSTRACT: This research aimed at investigating which sowing method is more suitable for the deployment of Urochloa ruziziensis to suppress the weed community in no-tillage. The design was a randomized block ones, with a 3 x 2 factorial design, in which the first factor was composed of three sowing methods (broadcast, broadcast with incorporation or line sowing) and factor B consisted in the application and non-application of the herbicide 2,4-D. On day 30 and 60 after sowing (DAS), the relative importance of the present plant species was determined. On day 120 and 180 DAS, the accumulation of biomass and the plant cover percentage on the soil provided by the cover crop and weed species were determined. Moreover, on day 180 DAS, the density of the existing... |

| ABSTRACT The aim of this paper was to conduct the phytosociological survey of weeds in cultivated areas with common beans and castor beans in the municipality of Ipameri, in the Southeast region of the State of Goiás, considering intercropping and monoculture. The survey was conducted 20 days after emergence of the crop using the square inventory method. We evaluated the green and dry biomass of weeds, their leaf area, frequencies, density and absolute and relative dominance, relative importance and similarity index, expressed as a percentage. Sixteen weed species were identified, distributed into 10 botanical families. The most important weed species in the Southeast region of Goiás for the cultivation of common beans and castor beans were: Cenchrus... |
