Analysis of the weed flora in the vegetable gardens in the village of Trmčare (Kruševac municipality) revealed the presence of a total of 44 weed species [23 weed, 19 weed-ruderal, 1 ruderal and 1 weed of meadows and pastures]. The recorded weed flora is dominated by representatives of the class Magnoliopsida (dicotyledons, broad-leaved weeds) with 38 species, while only six species are present from the class Liliopsida (monocotyledons, grass weeds). The analysis of life forms of weeds recorded in vegetable gardens shows a dominance of therophytes (70.45%), compared to geophytes (13.64%). Meanwhile, hemicrypthophytes make 11.36% of the weed flora and thero-hemicrypthophytes only 4.55%. The number of weeds was not high, because the inter-row cultivation was done every ten to fifteen days, and weeds were manually removed in the rows, around the plants. Regardless of the mechanical removal of weeds, the diversity of the weed flora was not negligible. In all observed vegetable gardens under organic production, the most frequent winter weeds were: Camelina sativa (L.) Crantz., Poa annua L., Myosotis arvensis (L.) Hill., Veronica persica Poir., Cerastium glomeratum Thuill., Lamium purpureum L. Of the early spring weeds the most frequent were Chenopodium polyspermum L., Polygonum lapathifolium L., Polygonum persicaria L., Polygonum convolvulus L, and Galium aparine L., and of the late spring weeds the most often present were Chenopodium album L., Amaranthus retroflexus L., Amaranthus hybridus L., Setaria viridis (L.) P. B., Hibiscus trionum L., and Portulaca oleracea L.
