| Tartalmi kivonat: | In several years lasting period occur great numbers of harmful organisms that cause decrease in crops yield. The most frequently occurring weed species cause great damages in agricultural crops, with potential yield loss of 34% [5]. They compete with the crops for water, space, light and nutrients and are hosts to insects and pathogens [8]. During 2014 allelopathic influence of Xanthium strumarium L. on maize yield (Zea mays L.) was studied in field conditions. Beside water extract from plant dry weight of the studied weed species, extract of methanol was also used in different concentrations. Concentrations of 0.04, 0.02, 0.01 and 0.004 g of the plant dry weight per 1 ml of solution were used. The required material was made from weed species picked up in 3-4 leaves phenophases. The reduced maize yield was established in fields in which water extracts, as well as methanol extracts were used. In comparison to untreated control variants, the reduced yield of 10.53-30.3% was established in treatments in which water extracts were applied. In relation to control plots, methanol treatments reduced yield for 20.26-36.32%. |
