Seed selection. Sown seeds should be clean, highly germinating, disease-free, whole, heavy. The seeds are cleaned of seeds and mixtures of other plants.

Land preparation. The sown areas are qualitatively cleared of past crop residues and weeds. The soil is loosened to a depth of 20–25 cm, after the large lumps are crushed, it is well leveled and irrigation furrows are obtained.

Sowing time. Onions are planted in three periods - early spring, summer-autumn and ninety. Onion seeds in spring in the southern regions from January 5 to 25, in the central regions from February 20 to March 10, in the northern regions from March 5 to 25, in the central regions from November 15 to December 15 and in the northern regions from November 1 to March 1. in December, in the summer-autumn period in the northern regions from August 15 to September 1, in other regions from August 15 to September 10. Onion seeds weigh 10-1,2 kg in the spring, 1,5 kg in the summer-autumn and nineties. is spent. Depending on the slope of the ground, the row spacing should be 2-70 cm. are planted in a four-row manner. Seeds are buried in the ground to a depth of 90–1,5 cm. After sowing the seeds are mixed with the husk into the soil.

Care. For planting onions in the spring, the furrows are removed in the fall. In the summer-autumn and nineties, onions are planted after the middle, summer vegetables, potatoes and grain.

Fertilization. Onions are a root vegetable, and the root system is mainly located close to the top of the soil. Therefore, it requires a lot of essential nutrients in the upper part of the earth. On gray soils, an average of 10 kg of nitrogen, 30 kg of phosphorus and 22 kg of potassium should be applied to every 9 sots of land. Meadow and meadow-swamp soils require 25 kg of nitrogen, 20 kg of phosphorus and 8 kg of potassium. When growing onions in saline, low-quality meadow bald, bald soils should give 32 kg of nitrogen, 22 kg of phosphorus and 10 kg of potassium.

Irrigation. The water requirement of the crop increases especially during the period of germination and onion head formation. Only at the end of the growing season and when the onion heads are ripe does the plant's need for water decrease slightly. On the gray soils with deep groundwater, onions are watered every 7–10 days in late spring and early summer. After the growth of the bulb stops, the crop is watered twice at intervals of 12–14 days, and watering is stopped one month before harvest. In areas close to groundwater, onions should be watered 7-9 times during the growing season.
