This study is known as allelochemical effect of white cabbage (Brassica oleracea L.) seedlings
of weeds purslane (Portulaca oleracea L.), lamb's quarters (Chenopodium album L.), black
nightshade (Solanum nigrum L.) and redroot pigweed (Amaranthus retroflexus L.), with the culture
plant maize (Zea mays L.) and sugarbeet (Beta vulgaris L.) seed germination was carried out between
2018-2019 in order to determine the effect. Methanol and aqueous extracts (30, 40, 50 %) of dry
and fresh white cabbage seedlings were used in the study. While none of the practices of maize plants
were effective, only dry plant methanol applied to sugar beet. The best result in weed seeds was
obtained in dry aqueous application of 50 % concentration in black nightshade. Purslane, lamb's
quarters and redroot pigweed have generally shown the highest effect of 50% concentration of fresh
plant methanol application. There are significant differences between the results obtained from
cultivated plants and weed seeds which is an important result in terms of transferring this study to
practice.
