Vyhodnocení intenzity zaplevelení polních plodin v podmínkách odlišného střídání plodin
 Hrubý, Roman
In the thesis, I focused on evaluating the intensity of weed of field crops, depending on their substitution and different tillage. The intensity of the weed was assessed in 2016 at the experimental station of the Mendel University in Žabčice. Weed evaluation was carried out in spring barley crops, which were planted in two field trials with different crop rotation. The first field trial is a long spring barley monoculture, which was established in 1970. In the second field trial is Norfolk rotation by rotation. In both experiments, there are two variants of tillage, and traditional and minimization. Evaluation of the intensity of weed infestation was carried out before the application of herbicides. The evaluation has been found that species composition of weeds in spring barley has a significant effect rotation. The variants with long-term monoculture of spring barley were found significantly fewer individuals than weeds on versions with Norfolk coppice.
