This article presents the results of experiments conducted on developing a new resource-saving method for producing quality seeds of the onion variety "Istiqbol" by leaving the bulbs in place and burying them. According to the research, the physiological processes in the onion bulbs did not stop, and due to the developed root system, the emergence of flower stalks, flowering time, and seed ripening period extended by 20-34 days compared to the control group. As a result, yields reached 532 kg on August 30, 515 kg on September 9, and 491 kg on September 19, which is 14.2-23.7% higher than the control variety.
