- Abstract
Survey of weed population in seedling alfalfa was conducted in 2005 in 4 localities in Pelagonia region. The objective of this study was to identify weeds of importance and to determine quantitative and qualitative structure of weed population in seedling alfalfa. During the study 20 weed species were registered and determined in all localities. The maximum weed species were registered in Poeševo (16), while the minimum (12) were registered in Logovardi. The weediness in the forth localities was high. Weed density was highest in Logovardi (197.0 plants m-2) followed by Novaci and Kravari (177.6 and 168.4 plants m-2, respectively). The lowest weed density was recorded in Poeševo (130.7 plants m-2). Polygonum aviculare, Echinochloacrus galli and Chenopodium album were the most dominant weeds. By taxonomic aspect, the weed flora is distributed in 9 families. 17 weed species are dicotyledons and 3 weed species are monocotyledons. Terophytes were dominant life form category in seedling alfalfa. They paricipated with 17 species. Detected weed population indicated that habitats in the forth localities are with favorable thermal and light regimes, slightly acid to neutral soil pH, -moderately moist and with medium to high supply of mineral matter.
