| This research aimed to identify the floristic composition of weed communities present in the agricultural area, cultivated with winter cereals and managed under integrated crop livestock. The study was conducted in the experimental area of the Western Paraná State University, Campus Marechal Cândido Rondon, in EUTRUSTOX Eutrophic, with a randomized block design in bands, with four replications. The treatments consisted of three different winter cereals (oats IPR 126, triticale IPR 111 and wheat BRS Tarumã) with different managements: ungrazed, one grazing and two grazings. The grazing was done in two days, until the residual height of 15 cm of each forage, using Holstein cows. The phytosociological survey was conducted in each plot 20 days after harvest... |

| Soil is a finite resource, limited and non-renewable. The type of soil management is crucial to the sustainability of hydrological and productive potential of a watershed. This study aimed to diagnose the current state of the watershed of the Guará River, performing characterizations of the physical and environmental management tools such as use territorial environmental and land. The investigative unit was the soil in order to find the main agents of degradation, and finally recommend the best ways to watershed management, minimizing soil degradation.The land use is the most relevant for agriculture (65.9%) cultivated with soybeans, corn and wheat. The area used for pasture was (11.8%) used for dairy cattle feeding. The watershed has slopes 0-13 degrees,... |

| Mixed systems of exploitation of crop and livestock have called attention to the advantages over isolated systems of farming or ranching. Therefore, the objective of this study was to evaluate the influence of seeding rates of Brachiaria brizantha (0.0; 5.0; 10.0 e 15.0 kg ha-1) in the variables of corn productivity and B. brizantha plant stand when cultivated in the consortium. The experiment was established in a randomized complete block design with four replications using the maize cultivar Pioneer 30K64Y sown under the spacing of 0.90 m between rows. We evaluated the number of kernel rows, number of kernels per row, ear length, ear diameter, ear height, plant height, plant population and productivity in corn, as well as plant stand in B. brizantha.... |
