Smooth brome Aira

Genetic Potential and Selection of 'Ayra' Brome Grass

Developed by the Institute of Fodder of the NAAS of Ukraine, the 'Ayra' variety represents a specialized solution for establishing long-term, high-yield pastures and hayfields. The breeding program focused on maximizing forage production stability within the variable climatic conditions of Ukraine.

Technical Specifications and Performance Metrics

• Vegetation Dynamics: The variety exhibits high regrowth vigor, allowing for 2–3 full cuts per growing season, which significantly enhances total biomass yield per hectare.
• Root System Architecture: A robust, deep-penetrating root system enables the plant to access subsoil moisture, providing resilience during mid-summer dry spells.
• Stand Density: 'Ayra' is noted for its excellent tillering capacity, forming a dense sod that prevents weed encroachment and withstands grazing pressure.

Operational Benefits for Livestock Farms

The primary advantage of the 'Ayra' variety lies in its longevity. Under proper management, the sward remains productive for 5–7 years, reducing the annual costs and labor associated with reseeding. The biochemical profile of the forage—characterized by optimal protein and fiber ratios—ensures high palatability for livestock, directly impacting milk and meat yield performance. 'Ayra' is an essential component for operations looking to optimize their feed base and minimize long-term operational expenses in forage production.
