Abstract

The field study was conducted in April 2006 in a long-term fertilization experiment that was set up in 1983. The aims of this study are to compare the weediness in plots with nitrogen-phosphorus-potassium (NPK), NPK + farmyard manure (FYM), and NPK + stalk treatments and to study the effect of increasing N doses on the weeds and winter wheat plants. The bifactorial test was arranged in a split-plot design with three replications. The treatments were the following: 0, 50, 100, 150, and 200 kg ha -1 N, 100 kg ha -1 phosphorus pentoxide (P 2O 5), and 100 kg ha -1 potassium oxide (K 2O). Three weed species were dominant in the experiment: Veronica hederifolia, Consolida regalis, and Stellaria media. The NPK treatment resulted in the smallest average weed cover. The significantly greatest weed cover was found on the plots treated with NPK + FYM, but the greatest biomass production of winter wheat was measured also in the NPK + FYM treatment, which resulted in a good crop competition. The weed cover was increased proportionally by the rising N doses. The effect of increasing N rates was positive on the winter wheat biomass and on wheat competition to the weeds. Results of our study show that we can manage weeds better using favorable plant nutrition.
