Sweetclover Lazar

Technical Profile of 'Lazar' Sweet Clover

The 'Lazar' yellow sweet clover variety, bred by the Siberian Federal Scientific Center for Agrobiotechnologies RAS, is a specialized crop designed for regions requiring high biomass productivity and stress tolerance. Its technical efficiency is driven by a strong growth habit and soil-enrichment capabilities.

Development and Growth Parameters

With a vegetation period of 80–120 days, the crop fits well into varying climate zones, utilizing early-season moisture efficiently. Reaching a height of 150–200 cm, 'Lazar' produces a substantial volume of green mass. To maximize feed quality, harvesting must be executed before full flowering, as the high-stature stems tend to lignify, which impacts digestibility.

Seed Characteristics and Sowing Precision

The 1000-seed weight is between 1.8–2.2 grams. This fine seed profile necessitates precise drill calibration and shallow planting depths (1–2 cm) to ensure optimal germination. Due to these small seed dimensions, soil compaction after seeding is vital for maintaining capillary moisture contact.

Key Application Areas

• Forage Production: Its substantial vegetative growth makes this variety a primary choice for hay production and green manure systems.
• Apiculture: The extended flowering period provides a stable, high-quality nectar source, positioning 'Lazar' as an essential asset for honey production.
• Soil Management: The deep root architecture serves as an effective tool for soil aeration and natural nitrogen fixation, significantly improving structural integrity for subsequent crops.

The variety shows a notable resistance to abiotic stresses, allowing it to perform consistently even in suboptimal or nutrient-depleted soil conditions.
