Uses of : Landscaping, Medicinal, Culinary, etc.
Erosion control: Hairy vetchвАЩs capacity to provide a heavy mulch aids in soil and water conservation.
Crop: Hairy vetch is grown as a cover preceding such crops as safflower, corn, tobacco, cotton, rice, tomatoes, and other vegetables. Hairy vetch is valuable for use in no-till corn rotations, especially in regions that are less favorable for clover and pea cultivation. It may also be used in orchards and vineyards. Hairy vetch is noted for its ability to fix large quantities of nitrogen.
Livestock: It is grown for hay, pasture, silage, seed, or as interim cover on disturbed soil.
Vicia villosa Roth, hairy vetch, is a vining, winter-active legume. It may be annual or biennial. It has a shallow root system. Stems may grow 2 to 5 feet long. Leaves bearing several leaflets grow perpendicular to the stem, and may terminate in tendrils. Stems and leaves of hairy vetch are pubescent (covered with a soft woolly fuzz) and tufts are present at the tips of stems. Flowers are purple. Seeds are round and black, and develop inside elongated and flattened pods.
Required Growing Conditions
Hairy vetch is a hardy type of vetch suited to wetter soil and colder winters than other winter-active legumes. Hairy vetch develops best under cool temperature conditions, on fertile loam soils; it is also productive on sandy or clay soils. It has been reported to grow well on light soils that are too sandy for crimson clover. It is only moderately sensitive to soil acidity.
Hairy vetch is distributed throughout the entire United States.
Cultivation and Care
Hairy vetch is planted in the fall wherever it is grown. It is normally seeded at 20 to 40 pounds per acre. Due to the vining, climbing habit of the plant, it is often sown in combination with rye so the rye may provide some support. In a mixture, 50 pounds of rye and 15 to 20 pounds of vetch per acre should be used.
General Upkeep and Control
Hairy vetch performs well in rotations with conventional and no-till planted row crops. In these systems, the fall planted legume is either mechanically or chemically killed 2 to 3 weeks prior to planting or it is sprayed at planting. A heavy disking may be advantageous prior to turning or it may be sufficient as a primary operation depending on the top growth of the vetch. The row-crop is then planted conventionally or no-tilled into the cover crop. The legume decomposes, providing nitrogen for the following crop. When grown for hay, vetch is generally cut when the first pods are set. It may be cut using a mower with a swather attachment. If grown as a seed crop, hairy vetch is harvested when the lower pods are ripe to avoid shattering. If carefully managed, hairy vetch may be grown with Bermudagrass. Vetch volunteers profusely when allowed to disseminate seed.
Pests and Potential Problems There are no serious insect or disease pests of mature hairy vetch; however, the seed is highly susceptible to vetch bruchid (Bruchus brachialis) injury. This insect pest is largely responsible for poor natural reseeding of hairy vetch in pastures.
