Meziplodiny a zaplevelení obilnin

The aim of this master’s thesis was to determine the types of weeds in intercrops and subsequent cereals, to evaluate changesin weeding and to estimate the long-term effects of intercrops on cereal weeding. The weeding rate was evaluated using a numerical method. In the company Hoštická a. s., weeding was observed in various mixtures of intercrops and subsequently cultivated spring barley and maize. In a field experiment carried out at the experiment station Ivanovice na Hané weeding was observed in a barley monoculture after a sown intercrop and after skimming. The results were processed using statistical methods. Weed species were also divided according to different criteria (according to biological properties, according to origin, according to invasive status and according to harmfulness). The results show that monoculture of barley can increase the species representation of weeds. In the long term, intercrops can suppress some types of weeds. Intercrops allow the sprouts of the previous crop to emerge and prevent weeding of subsequent crops. As the diversity of intercrops increases, the list of ecosystem services expands.
