Ivanna Poliska

Agrotechnological potential of the "Ivanna Poliska" variety

The 2025 novelty from the NSC "Institute of Agriculture of NAAS" — winter soft wheat "Ivanna Poliska" — is designed as a high-yielding variety for the steppe zone of Ukraine. Given its genetic predisposition to challenging growing conditions, this variety requires precise adherence to agrotechnical regulations to unlock its grain productivity potential.

Recommendations for sowing and maintenance

• Timing and rates: Considering the late heading type, the variety requires optimal early sowing dates to ensure high-quality tillering before entering winter. The semi-prostrate growth habit facilitates efficient use of the feeding area.
• Soil conditions: The variety demonstrates adaptability to steppe soils, but it is critical to ensure a balance of nitrogen nutrition during the stem elongation phase, given the strong waxy bloom on the upper internode, which serves as a protective reaction to intense insolation.
• Phase-based care: During the spring tillering phase, attention must be paid to protection against leaf infections. Despite the moderate pubescence of the nodes, the variety requires monitoring during the grain-filling period, as the medium-sized red grain needs sufficient moisture during the milk-wax ripeness phase.

"Ivanna Poliska" possesses distinct morphological defense traits: a strong waxy bloom on the flag leaf and upper internode minimizes transpiration, making this variety promising for farms operating in conditions of water scarcity.
