Title of the thesis:Reaction of weeds on different doses of nitrogen fertilizers
Summary:Abstract The aim of bachelor work was to assess weed infestation in spring barley in different variants of nitrogen fertilizers. The assessment was carried out in log-term monoculture of spring barley, in the field trial which was established in Žabčice in 1970. Three variants of nitrogen fertilization, first variant with 30 kg N ha-1, second 60 kg N ha-1 and third 90 kg N ha-1. The impact of two other factors was evaluated: straw management -- straw was incorporated into the soil; straw was picked up and burned. The last factor -- soil tillage has two variants -- conventional tillage and minimum tillage. The obtained results were analyzed using DCA and RDA method. Only some of the presented weeds were directly influenced with nitrogen fertilization (Stachys palustris, Lamium purpureum, Persicaria lapathifolia). Other weed species were more influenced with other factor than nitrogen, especially with soil tillage and straw management.
Formula clause:Bachelor work is schooltask and can be use for commercial purpose only with agreement head of diploma work and dean of faculties AF MZLU in Brno.
Key words:nitrogen fertilization, spring barley, weeds
