Studies were carried out in the years 1998-00 on the influence of the sowing date and standard on the yields and inflorescence quality of the annual (Lonas annua (L.) Vines et Druce). Seeds were sown in rows 25 cm apart directly into the ground over three different periods, on the following dates: 1st period - May 4th, April 29th and 28th, 2nd period - May 14th, 10th and 8th, 3rd period - May 24th, 20th and 19th. The seedlings were not thinned out. On each of the sowing dates planned, the following sowing standards were applied: 40, 60, 80, 100 and 120 g/100 square m. After reaching harvest maturity (80 percent of the inflorescence on the plantation in full bloom, with inflorescence shoots of a red-brown colour), the plants were removed from the field. Of the sowing dates studied, the plants with the most abundant flowering (10.62 pieces) with the highest number of capitula in the inflorescence (18.49 pieces) were obtained from the earliest sowing date. The lowest sowing standard of 40 g/ 100 square m influenced the inflorescence quantity most favourably. Plants from this combination showed a tendency towards the most abundant flowering
