Rogiznyanka

Agrobiological Potential of the Rogiznyanka Variety

The Rogiznyanka soybean variety, developed by the Bukovinian State Agricultural Research Station, represents a prime example of adaptive breeding focused on yield stability within the Ukrainian climate. Its technical value lies in the balance between earliness and the efficiency of organic compound accumulation.

Vegetation Parameters and Field Architecture

With a maturation period of 90–100 days, this variety is classified as early-maturing (Group 000). This allows it to capitalize on soil moisture during the first half of the summer, effectively bypassing the risks associated with late-season droughts. The plant height of 80–90 cm is ideal for mechanized harvesting; the compact habitus minimizes lodging, while the lower pod attachment height of 14–16 cm is critical for reducing harvesting losses.

Seed Biochemical Profile

Rogiznyanka exhibits a high-quality grain composition that is highly sought after by processing industries:

• Protein content: 39–41%. This high protein level ensures marketability for both export and animal feed production.
• Oil content: 19–20%. A stable oil ratio combined with robust protein levels reflects high nutritional density.

Field experience indicates that the variety is highly responsive to planting density management, which, when combined with its intrinsic biological traits, allows for uniform pod formation and efficient harvesting across the entire field.
