Zaplevelení jarního ječmene v podmínkách odlišného střídání plodin

In my diploma thesis I deal with weed infestation of spring barley under different crop rotation conditions. I evaluated the weed intensity in 2016 - 2018 at the experimental station of Mendel University in Žabčice. Weeds were evaluated in spring barley stands, which were grown in two field trials with different crop rotation. The first experiment was a long-term monoculture of spring barley, which has been in Žabčice since 1970. In the second attempt, it was evaluated in crop rotation crops according to the Norfolk crop rotation. In the first and second attempts I used two variants of soil cultivation, traditional and minimizing. Weeds have always been evaluated before herbicide application. Evaluation of weed intensity showed that crop rotation has a great influence on the species composition of weeds in spring barley. In the variant with long-term spring barley monoculture, significantly fewer weed plants were observed than in the variant with the Norfolk crop rotation
