abstract = "The analysis of weed flora in organic production of spices and medical herbs (nettle, basil, spearmint, dill, alpine savory, marigold and lemon balm) a total of 21 species were found. In the studied flora is dominated therophytes with 71.42%, while geophytes and hemicryptophytes are present both with 14.29%. The largest number of detected species were weed-ruderal plants (80.96%). They are followed by ruderal and segetal weeds, both present with the 9.52%. Phytogeographic analysis of weed flora indicates the dominance of the species which are widely distributed with 80.95% (Cosmopolitan - 47.62%, Eurasian - 19.05%, Adventive - 9.52% and Circumpolar - 4.76%). Plant species which are less distributed are present with 19.05% (Pontic- Central Asian - 9.52%; Sub-Atlantic - 4.76% and Central European - 4.76%). Ecological analysis of the weed flora was according Landolt (2010) and it showed that detected weeds are adapted to the conditions of moderately continental climate of the study area (Kx = 3.19). The studied agroecosystem is characterized as warm (Tx = 4.05) and well lit place (L = 3.91). It was found that the investigated site is fresh (Fx = 2.48), weakly acid to weakly neutral chemical reaction (Rx = 3.48), with a medium to relatively rich in mineral matter (Nx = 3.76), weakly saline (Ss - 33.33%), moderately rich in organic matter (Hx = 2.81) and moderately aerated (Dx = 2.62)., Analizom korovske flore u organskoj proizvodnji začinskog i lekovitog bilja (koprive, bosiljka, nane, mirođije, čubra, nevena i melise) konstatovana je ukupno 21 vrsta. U ispitivanoj flori dominiraju terofite sa 71,42%, dok su geofite i hemikriptofite prisutne sa po 14,29%. Najveće je učešće korovsko-ruderalnih biljaka (80,96%). Slede ih ruderalni i segetalni korovi prisutni sa po 9,52%. Biljnogeografska analiza flore pokazuje dominantno prisustvo korovskih vrsta širo- kog rasprostranjenja sa 80,95% (kosmopolitskih - 47,62%, evroazijskih - 19,05%, adventivnih - 9,52% i cirkumpolarnih - 4,76%). Biljne vrste užeg rasprostranjenja prisutne su sa 19,05% (pontsko-centralnoazijske - 9,52%; subatlanske - 4,76% i srednjeevropske - 4,76%). Ekološka analiza flore urađena je prema Landolt (2010), a pokazala je da je ispitivana korovska flora dobro prilagođena uslovima umereno kontinentalne klime istraživanog područja (Kx = 3,19), a ispitivani agroekosistem okarakterisan je kao topao (Tx = 4,05) i dobro osvetljen (Lx = 3,91). Utvrđeno je da je ispitivano stanište vlažno (Fx = 2,48), slabo kisele do slabo neutralne hemijske reakcije (Rx = 3,48), umereno do bogato mineralnim jedinjenjima (Nx = 3,76), slabije zaslanjeno (Ss - 33,33%), umereno bogato organskim materijama (Hx = 2,81) i umereno aerisano (Dx = 2,62).",
