Plevele ozimé pšenice a zpracování půdy

The bachelor thesis is focused on the issue of winter wheat weeds and their relation to the soil processing. Three different soil treatment technologies and two precursors were studied in the experiment. The results were based on gradient length analysis, as determined by DCA segment analysis (Early Correspondence Analysis). The redundancy analysis (RDA) was also used and the data was processed using the Canoco 4.0 computer program. In traditional soil cultivation ware found the lowest values of weed appearence, with the exception of Veronica polita. The medium occurrence of weed species showed the use of minimize soil tillage. There were found species Capsella bursa-pastoris, Lamium amplexicaule, Stellaria media and Thlaspi arvense, but their incidence was significantly lower compared to non-tillage technology. The non-tillage technology showed, with exception of Veronica polita, the highest values of weeb species especially in case of Capsella bursa-pastoris
