Between the years 1998–2000, comparative studies were carried out on the influence of propyzamide (0.750 and 3.500 kg ha^-1), trifluraline (0.625 and 1.000 kg ha^-1), propachlor (3.250 and 4.450 kg ha^-1), chloridazone (4.615 and 6.153 kg ha^-1) and metolachlor (1.440 and 1.728 kg ha^-1) on the weed population, (Nigella damascena L.) cultivated for dried bouquets in the soil-climatic conditions of the Lublin Upland and on their influence on cultivated plants. Propachlor proved to be the most effective preparation in weed control. Chloridazone caused inconsiderable and passing damage of seedlings Nigella damascena L.
