Daňhel, Vladimír
The aim of this thesis was to evaluate weed infestation of chosen crops, to compare weed infestation among each crop and evaluate used regulation interventions, eventually to suggest another solution. Evaluation was made in winter oilseed rape, winter wheat and in spring barley. In the winter oilseed rape were found Viola arvensis, Triticum aestivum, Thlaspi arvense, Chenopodium album, Geranium pusillum, Fallopia convolvulus, Stellaria media, Lamium purpureum, Capsella bursa-pastoris, Veronica persica, Tripleurospermum inodorum and Cirsium arvense. In winter wheat were Viola arvensis, Veronica persica, Brassica napus ssp. napus, Lamium purpurem, Galium aparine, Geranium pusillum, Capsella bursa-pastoris, Thlaspi arvense, Chenopodium album, Stellaria media, Matricaria recutita and Cirsium arvense. In spring barley were Viola arvensis, Raphanus raphanistrum, Lamium purpureum, Veronica persica, Thlaspi arvense, Fallopia convolvulus, Polygonum aviculare, Galeopsis tetrahit, Chenopodium album, Galium aparine, Geranium pusillum, and Matricaria recutita. Weed infestation was processed by canonical correspondent analysis (CCA). Finally it was suggested to use different methods for weed regulation.
