The article presents data on the number of seedlings at the beginning and end of the growing season of the earlyripening sunflower variety Sam QXI 20-80 when planted as a repeated crop in areas freed from cereal crops at different (July 1; July 10; July 20) terms and in planting schemes of 70x20x1; 70x25x1; 70x30x1; 70x35x1; 70x40x1 cm. As the planting season was delayed from July 1 to July 10 and from July 10 to July 20, the number of seedlings decreased depending on the variety. In all the studied planting schemes, due to the expansion of the feeding area from 70x20x1 cm to 70x40x1 cm, good plant growth and development were observed, and it was determined that the number of bushes preserved as a percentage of the planned number of bushes increased. In general, according to all the studied options, the highest indicator in terms of percentage of the planned number of bushes was observed in the 70x40-1 cm planting scheme of the July 1 planting period (97.1% at the beginning of the operational period and 91.6% at the end of the operational period).
