Abstract	Ambrosia artemisiifolia L. jedna je od najnapasnijih i najštetnijih korovnih vrsta u svijetu i Hrvatskoj. Hipoteza istraživanja je pretpostavka da na rast i volumen jedinki ambrozije utječu biotički (interspecifična i intraspecifična kompeticija) i abiotički (temperature i oborine) čimbenici. Trogodišnji stacionarni poljski pokus postavljen je na lokalitetu Popovača u proljeće 2014. Odabir lokaliteta zahtijevao je visoku gustoću zakorovljenosti ambrozijom te mogućnost neuznemiravanja pokusa naredne dvije godine. Na 12 stacionarna mjerna kvadrata utvrđivana su morfološka (volumen biljaka), fenološka (razvojne faze ambrozije) te reproduktivna (broj ženskih i dužina muških cvatova) svojstva ambrozije u sve tri godine istraživanja u dva roka (proljeće i jesen). Rezultati istraživanja ukazuju na značajne varijacije između godina istraživanja u volumenu biljaka, broju ženskih i muških cvatova ambrozije te produkciji sjemena i polena po jedinici površine. Od okolišnih čimbenika, interkompeticija (prisustvo ostale vegetacije) je najjače reducirala volumen biljaka te količinu sjemena i polena ambrozije. Rezultati istraživanja ukazuju na visoku sposobnost prilagodbe ambrozije na okolišne čimbenike što predstavlja opasnost za daljnje širenje na nova staništa.
Abstract (english)	Ambrosia artemisiifolia L. is one of the most noxious and harmpful weed species in the world and Croatia. The hypothesis of research is the assumption that growth and volume individuals of common ragweed are influenced by biotic (interspecific and intraspecific competition) and abiotic (temperature and precipitation) factors. A three-year stationary field experiment was set up at Popovača locality in spring 2014. The selection of locality required a high density of common ragweed and the possibility of non- cultivation (untreated) experiments over the next two years. Morphological (plant volume), phenolic (amphiphase developmental phases) and reproductive (number of female and male flower buds) were determined on 12 stationary metering squares in all three years of research in two deadlines (spring and autumn). The placement of the experiment show significant variations between years of research into plant volume, number of female and male blooms, and production seeds and pollen per unit area. Of the environmental factors, intercompetition (presence of other vegetation) was the strongest in reducing the volume of plants and the amount of seeds and pollen of common ragweed. The research results indicate a high ability to adapt the common ragweed to environmental factors, which is a danger to further spread to new habitats.
