Agrotechnics.
Sowing seeds for seedlings is carried out in March, planting seedlings in open ground - in early May. Sowing seeds directly into the open ground is carried out in late April - early May, to a depth of 1.0-1.5 cm. Sowing scheme, planting seedlings: 5-7x10-15 cm. In the last 20-30 days of the growing season, fertilise with fertilizers containing calcium.
1,0 g = 250-300 seeds.

* Onions require a little water to form crops. But due to the compact and shallow root system, onions are demanding in terms of soil and air moisture. Moreover, its requirements for soil moisture in different periods of growth are not the same. Onions especially need soil moisture in the first 2 weeks after sowing and for 2-3 weeks after germination, when intensive leaf formation and regrowth of the root system occur. The highest water requirement of onions is during the period of leaf growth and bulb formation. Later, excess moisture retards the development of the bulbs and worsens their shelf life. In general, the yield of onions largely depends on the moisture supply of the upper 30-centimetre soil layer. Therefore, during the period of intensive growth of leaves and root system, the moisture content of the upper soil layer should be increased, and during the formation and growth of the bulb, this entire layer should be well moistened.
