Sweetclover STAVROPOLSKY

Biological potential of the «Stavropolsky» sweet clover

The «Stavropolsky» sweet clover (Melilotus) is a product of breeding research conducted by the Stavropol State Agrarian University. This variety represents an example of adaptive breeding aimed at increasing the productivity of forage lands and enhancing soil fertility. The plant height ranges from 80 to 150 cm, ensuring an optimal balance between biomass volume and ease of mechanical harvesting.

Agrotechnical development features

The key value of this variety lies in its structural characteristics and life cycle:

• Stem structure: The plants demonstrate high leafiness, which is crucial for producing high-quality hay or haylage with a high protein content.
• Root system: The well-developed taproot system allows for efficient water uptake from deeper soil layers, ensuring stable growth even during dry periods.
• Soil enrichment: As a member of the Melilotus genus, this variety actively contributes to atmospheric nitrogen fixation, making it an essential crop in rotations for restoring soil structure and nutrient levels.

Practical application and breeding

The development of the variety was led by experts A.I. Voyskovoy, A.A. Krivenko, and V.I. Zhabina. The breeders successfully achieved a combination of resistance to abiotic stress factors and high regrowth intensity after mowing. In practice, «Stavropolsky» demonstrates rapid biomass accumulation, allowing for multiple cuts per season under proper agricultural management. The variety is suitable for both establishing permanent hayfields and as a green manure crop, providing intensive organic matter accumulation in the soil profile.
