AB  - A field experiment was conducted in order to estimate the influence of different arrangement patterns of maize plants (Zea mays L.) in combination with low rates of herbicides on weed infestation and on production parameters of the crop. The maize was sown at 70-, 50-, and 35-cm row space with the same crop density. The weed biomass declined with smaller row spaces and was, on average, the lowest with the 35-cm row space; even though the arrangement patterns of the maize plants had no significant effect on the average values of the weed biomass. The interaction of the arrangement pattern and the herbicide rate significantly influenced weed biomass. Maize grain yield expressed the greatest variation under the effects of applied factors, but did not differ significantly between treatments with the full and the half rate of herbicides. The results indicate that it is possible to control weed infestation level if maize is grown with increased spatial uniformity and combined application of other practices such are herbicides. In such a way, maize plants are more competitive against weeds and even lower amounts of herbicides could be applied in order to achieve high yields.

AB  - Growing competitive crops is an important component of the integrated weed management system, although selection of genotypes with the increased competitive ability is rather difficult. The possibility of reducing weed infestation by increasing the competitive activity of crops by growing genotypes, i.e. hybrids that better 'endure' a greater density, depends on the FAO maturity group and morphological properties of a genotype, environmental conditions and the growing regions. The competition between maize and weeds varies over the modified crop arrangement pattern. The greatest weed infestation is recorded in the crops of the sparse-spaced plants, while the height and the weight of weeds are significantly lower in closely-spaced plants. The height, growth intensity in the initial stages, embryo vigour and leaf area of the plant are important for a greater competitive ability, as they are components of competitive effects of crops on weeds. Weed infestation and maize hybrids yielding were studied in dependence on the hybrids arrangement pattern and the application of herbicides. Obtained results show statistically significant differences in the weed fresh weight, but only in certain years and in accordance with differences in the height and the leaf area of ZP maize hybrids.
AB  - Gajenje kompetitivnijih useva je važna komponenta integralnog sistema suzbijanja korova, iako je selekcija genotipova sa povećanom kompetitivnom sposobnošću dosta teška. Mogućnost smanjenja zakorovljenosti na osnovu povećanja kompetitivnog delovanja useva gajenjem genotipova tj. hibrida koji bolje 'podnose' veću gustinu, zavisi od FAO grupe zrenja i morfoloških karakteristika genotipa, uslova spoljašnje sredine i područja gajenja. Kompeticija između kukuruza i korova se menja sa promenom gustine i rasporeda gajenih biljaka. Najzakorovljeniji su usevi retkog sklopa, dok su visina i masa korova u usevima gustog sklopa znatno niže. Za veću kompetitivnost genotipa kukuruza u odnosu na korove važni su visina, intenzitet rastenja u početnim fazama, vigor klijanaca i lisna površina biljke, koje su komponente konkurentskog delovanja useva na korove. U radu je ispitivana zakorovljenost i produktivnost različitih hibrida kukuruza u zavisnosti od prostornog rasporeda u kome su gajeni i primene herbicida. Rezultati pokazuju da su pri gajenju ispitivanih genotipova kukuruza utvrđene statistički značajne razlike u svežoj masi korova, ali samo u pojedinim godinama, u skladu sa razlikama u visini i lisnoj površini ZP hibrida.

AB  - The intensity of crop competition is mostly defined by population density and spatial arrangement of plants. The effect of plant arrangement pattern of maize, in combination with the application of different herbicide rates, on weediness and maize yields were studied at the Maize Research Institute, Zemun Polje, during 2004 and 2005. Different plant arrangement patterns were designed by combining three inter-row distances (70, 50 and 35 cm) as well as by plant spacing at uniform population density. Subvariants included the application of isoxaflutole + acetochlor herbicides after sowing but prior to maize emergence at three rates: recommended, half of the recommended rate and without herbicide treatment. The number of plants per species, fresh weight of weeds, biomass and grain yield of maize were analysed. Although there were no statistical significances, the number of plants per species and fresh weight of weeds declined with the decrease in inter-row distance and, on the average, their values were the lowest in the 35-cm variant in both years 2004 and 2005 (78.52 plants m-2 and 388.65 g m-2 vs. 105.78 plants m-2 and 191.54 g m-2, respectively). The different rates of herbicide application significantly affected weediness by reducing it in both years of investigation. Maize grain yield did not vary over treatments with the recommended and half the recommended rate at the different inter-row distances and on the average.
AB  - Intenzitet kompeticijskog delovanja useva na korove je uglavnom određen gustinom i prostornim rasporedom gajenih biljaka. U ogledu su ispitivani efekti prostornog rasporeda u kome se gaji kukuruz u kombinaciji sa primenom herbicida u različitim količinama, na zakorovljenost i produktivnost kukuruza tokom 2004. i 2005. godine u Institutu za kukuruz Zemun Polje. Različit prostorni raspored biljaka kukuruza je ostvaren kombinovanjem veličine međurednog razmaka (70, 50 i 35 cm) i razmaka između biljaka, u okviru iste gustine. Podvarijante su dobijene primenom herbicida isoxaflutole+acetohlor, posle setve a pre nicanja kukuruza u tri količine: preporučenoj, polovini peporučene količine i bez herbicda. Analiziran je broj jedinki i sveža masa korova, kao i biomasa i prinos zrna kukuruza. Iako nije bilo statističke značajnosti, broj jedinki i sveža masa korova su se smanjivali sa smanjenjem međurednog razmaka i u proseku imali najmanje vrednosti na varijanti 35 cm, kako u 2004. (78,52 jedinki m-2 i 388,65 g m-2), tako i u 2005. godini (105,78 jedinki m-2 i 191,54 g m-2). Primena herbicida u različitim količinama uticala je na značajno smanjenje zakorovljenosti u obe godine ispitivanja. Prinos zrna kukuruza se nije razlikovao između tretmana sa preporučenom i polovinom količine herbicida, u svim varijantama međurednog razmaka i prosečno.
