Maize Iziaslav 220 MV

Technical Profile of the Izyaslav 220 MV Hybrid

Izyaslav 220 MV is a simple corn hybrid developed by the Grain Growing Institute of the UAAS. With an FAO rating of 220, it belongs to the mid-early group, offering farmers significant flexibility in planning sowing and harvesting windows. The maturation period ranges from 90 to 110 days, making it a reliable choice for regions with varying seasonal temperatures.

Grain Morphology and Performance

The dent-type kernel is a defining characteristic of this hybrid, optimized for both high-yield grain production and high-quality silage. This architectural choice promotes efficient dry matter accumulation and excellent moisture release during the final stages of the vegetative cycle, reducing drying costs for grain producers.

Integrated Protection and Disease Resistance

The hybrid’s breeding program focused heavily on inherent plant resilience against biological threats:

• Phytopathology: It displays high resistance levels to common smut (Ustilago maydis) and significant tolerance against head smut in corn and sorghum, as well as onion stem smut, minimizing crop losses.
• Entomology: Engineered resistance to the European corn borer reduces dependence on chemical insecticides, ensuring structural integrity of the stem and minimizing ear damage.

Recommended Planting Density

The optimal plant population density depends on local moisture availability and the intended final use:

• Intensive grain production: 70,000–80,000 plants/ha.
• Standard technology (moderate moisture): 60,000–70,000 plants/ha.
• Low-moisture/Extensive management: 45,000–50,000 plants/ha.
