SIBIRYAK

Stable yields in challenging environments: Sibiryak onion

For farms operating in high-risk agricultural zones, choosing the right seed material is a matter of crop survival. Developed by specialists at the Tyumen State Agricultural Academy, the "Sibiryak" variety was designed to address the primary threats to the crop: high soil moisture and pathogenic microflora that cause rot. This bulb onion variety demonstrates excellent adaptability, maintaining its marketability even during mechanized harvesting.

Agronomic features and protection

The key advantage of this variety is its genetic resistance to fusarium rot. In intensive production environments where diseases can wipe out a significant portion of crops within weeks, such immunity minimizes the need for costly fungicide treatments. Sibiryak does not just resist rot; it ensures consistent bulb development within 90–100 days from emergence to technical maturity.

Cultivation practice and market potential

• Mechanized harvesting: The round-cuboid shape of the bulb makes it resilient to damage when passing through harvester equipment. The dense bulb structure significantly reduces the rejection rate.
• Weight indicators: The standard bulb weight ranges from 100 to 130 grams, which is ideal for both retail chains and food processing plants.
• Yield: The yield of marketable produce reaches up to 50 tons per hectare, making the variety highly profitable when proper agricultural techniques are followed.

Visually, Sibiryak is characterized by bright brown outer scales hiding quality white flesh. This combination makes it a versatile solution: the onion is equally sought after for fresh market use (due to its moderate pungency) and for processing. The produce handles transportation and long-term storage exceptionally well, which is critical for farms that cannot sell their harvest immediately after pulling it from the field.
