Sažetak
The aim of the research was to determine allelopathic potential of three weed species (Amaranthus retroflexus, Solanum nigrum, Sorghum halepense) on germination and growth of two onion cultivars (Holandski žuti and Srebrenac majski). Effect of water extracts from dry aboveground weed biomass in concentrations of 1, 5 and 10% (10, 50 and 100 g/l) was examined under laboratory conditions in petri dishes. The results showed that all extracts significantly decreased germination, root and shoot length and fresh weight of onion seedlings. A. retroflexus and S. nigrum extracts had greater inhibitory potential and reduced seedlings growth over 50%. Extracts in concentrations of 5 and 10% exhibited higher negative effect. Differences in sensitivity among onion cultivars were recorded.
