Botanical Description:

  1. Growth Habit:

    • Hairy vetch is a trailing or climbing annual legume.

  2. Height:

    • It can grow to a height of about 30 to 90 centimeters (12 to 35 inches).

  3. Leaves:

    • The leaves are compound, with several pairs of leaflets arranged along a central stem. Leaflets are oval to lance-shaped and have a hairy texture.

  6. Inflorescence:

    • The inflorescence is a raceme, with flowers arranged along a central stalk.

  7. Roots:

    • Hairy vetch has a deep taproot system that helps in soil penetration.

Uses:

  • Cover Crop:

    • Hairy vetch is widely used as a cover crop in agricultural rotations to improve soil fertility, suppress weeds, and prevent erosion.

  • Forage Crop:

    • It is utilized as a forage crop for livestock, providing high-quality feed.

  • Green Manure:

    • When plowed into the soil, hairy vetch serves as a green manure, enriching the soil with nitrogen.

Benefits in Agriculture:

  • Nitrogen Fixation:

    • Hairy vetch has nitrogen-fixing nodules on its roots, contributing nitrogen to the soil.

  • Erosion Control:

    • Its extensive root system helps control erosion by stabilizing the soil.

  • Weed Suppression:

    • Hairy vetch competes with weeds, helping to suppress their growth.

Habitat:

  • Distribution:

    • Native to Europe and Western Asia, it is widely cultivated in various regions.

  • Habitat:

    • Thrives in cool-season conditions, making it suitable for temperate climates.

Planting:

  • Season:

    • Typically planted in the fall for winter cover or in early spring.

  • Companion Planting:

    • Often used in companion planting with grains or other crops.

Management:

  • Termination:

    • Hairy vetch is terminated before seed set to prevent it from becoming invasive.

  • Rotational Benefits:

    • Rotating with other crops enhances soil health and fertility.
