During the vegetation period of 2010 in organic production of rocket salad - Eruca vesicaria (L.) Cav. in the open area 31 plant species were found in the weed flora. The investigation was made in the village of Kisač (Serbia). The analysis of life forms in the weed flora of rocket salad indicated that therophytes are predominant in the studied agroecosystem. Ecological analysis of the weed flora indicated that the studied site is moderately moist, neutral to slightly alkaline, meso-eutrophic, with a medium humus content, well aerated and non-saline. In the weed flora of rocket salad, plants adapted to full light and some shadow and thermophilic plants are predominant. These weeds are adapted to the conditions of a moderately continental climate. One of the biggest problems in organic production is weed control. Therefore, knowledge of the weed flora, its biological and ecological characteristics are a prerequisite for choosing the method of weed control and suppression.
