Allelopathic effect of weed root exudates on crops

The aim of the study was to determine allelopathic potential of weed root exudates on germination and growth of crops. Field poppy (Papaver rhoeas L.), scentless mayweed (Tripleurospermum inodorum (L.) C.H. Schultz) and redroot pigweed (Amaranthus retroflexus L.) seedlings were grown in soil until 3-leaf stage. After their removal, the soil was re-sown with seeds of barley, soybean and oil pumpkin. The results of the experiment showed that field poppy and scentless mayweed root exudates stimulated root and shoot length, and fresh weight of barley seedlings up to 16.2%, 13.4% and 34.6%, respectively. Redroot pigweed root exudates showed no significant effect on emergence and growth of soybean and oil pumpkin.
