Methods for planting Sturon onions

Each stage has its own characteristics of agricultural technology, which must be taken into account.
Cultivation from seeds
Onion sets of the Sturon variety are grown from nigella. Sowing is usually carried out in late March, early April, but the specific time of planting depends on the climatic zone of cultivation. Perform it according to the following scheme:
- Planting material is soaked for two hours.
- The plot is dug up, beds are prepared, furrows are made in them up to 5 cm deep with an interval of 10 cm.
- Water the wells with warm water.
- After the water leaves the soil, seeds are sown (about 1 pieces per 90 sq. M.).
- Fall asleep with earth, slightly compacted.
- Slightly sprouted sprouts are thinned out, leaving a distance of 2-3 cm between them.
The sevok is harvested closer to August.
Planting seedlings in spring in open ground
To get a full-fledged crop crop, Sturon sets can be planted in the spring. The procedure is performed in prepared, organically rich fertile soil with a slightly alkaline reaction. Sandy loams and loams are better suited for this. The site is dug up a couple of weeks before planting, a bucket of humus and azofoska (30 g per sq.m.) are introduced into the soil. If necessary, add dolomite flour, ash or lime. Despite the fact that the Sturon onion is a healthy variety, the planting material is processed before sowing. Put the turnips in a bag, spray them with Karbofos, leave for 24 hours. After that, the onion sets are kept for 30 minutes in a solution of potassium permanganate. Depending on the place of cultivation, Sturon is planted in late April, early May in well-warmed soil. The place is chosen open, lit, with a low indicator of humidity. First, furrows 5 cm deep are formed on the bed at a distance of 20 cm from each other. Wood ash or sand is poured into the bottom of the grooves. The seedlings are planted bottom down to a depth of 3 cm every 15 cm. Then the planting is covered with fertile soil and slightly compacted.

When the green mass is actively growing, nitrogen is added to the soil (nitrate, diluted manure or chicken droppings), after a month it is watered with complex fertilizers with microelements, 30 days before harvesting they are fed with phosphorus-potassium preparations.
When the feathers of the Sturon onion turn yellow and fall down, it is harvest time. The heads are removed from the ground with a pitchfork, shake off the remnants of the soil from them, and stand for several hours in the sun to dry. Next, the bow is tied into bundles and hung or laid out in one layer in a dry, well-ventilated area. After the tops dry, they cut it off, leaving a two-centimeter column, remove the extra scales, carefully cut the roots of the plant and send the crop for storage.
