dc.description.abstractThis paper deals with result of the effects of tillage systems on floristic composition weed synuzia of winter wheat in investigated period (2000/01-2002/03) on the chernozem luvic soil type. Tillage have a big influence on weed control and floristic composition, number of species individuals and biomass of weeds of winter wheat. The obtained results shows that the dominant species were from annuels Bilderdykia convolvulus (L) Dum., Sinapis arvensis L. and Agropyrum repens (L) Beauv., Convolvulus arvensis (L), Cirsium arvense (L) Scop., from perennials. The greatest number of species belonged to terrophytes in biological specter of weed communities. Mulch tillage had better effect in weed control than conventional and especially from no tillage systems. This is one of possibilities for crop technology rationalization for winter wheat and soil conservation. No-tillage increased total weed number annual and perennial species especially biomass. This tillage make weed control difficult.en
dc.description.abstractU radu je ispitivan uticaj tri sistema obrade zemljišta (konvencionalni i dva konѕervacijska: zaštitni i sistem direktne setve) na floristički sastav korovske sinuzije ozime pšenice. Ispitivanje je obavljeno na "Radmilovcu" eksperimentalnom dobru Poljoprivrednog fakulteta u Zemunu na zemljištu tipa izluženi černozem u tri vegetaciona perioda ozime pšenice od 2000/01-2002/03 god. Korovsku sinuziju useva ozime pšenice tokom trogodišnjih ispitivanja činilo je 18 vrsta korova. Dominantne korovske vrste bile su Bilderdykia convolvulus (L) Dum. i Sinapis arvensis L. od jednogodišnjih i Agropyrum repens L. i Convolvulus arvensis L., od višegodišnjih. Od ispitivanih sistema obrade zemljišta najveću efikasnost ispoljio je sistem zaštitne obrade u kome je dobijen najmanji broj jedinki korova po m2 (27.72) i najmanja biomasa 54.59 g/m2. Sistem direktne setve utiče na pojavu većeg broja jedinki, pre svega, višegodišnjih korova što utiče na ukupnu biomasu koja je u ovom sistemu obrade prosečno, ali i po godinama imala najveće vrednosti.sr
