Rolling and immediately planting has provided the greatest vetch control and weed suppression. The timing of this practice is essential for success. A nurse crop is suggested for establishment because hairy vetch produces low amounts of fall growth. The plant will grow vigorously throughout the winter. When a hairy vetch cover crop is plowed into the soil, significant amounts of nitrogen are restored. 30 Seeding Rate (Broadcast with Incorporation) 1.3 Ounces/100 Sq. If the companion is rye, triticale, wheat, or barley, the small grain will survive the winter with the hairy vetch. Best seeded in late winter or early spring. The hairy vetch and winter rye combination are highly recommended for fields that will not be planted in spring. Compaction reduction. Optimal Soil Conditions. JavaScript seems to be disabled in your browser. Although hairy vetch is not generally included as a rotational crop on the herbicide label, alfalfa and clover rotational restrictions should be similar to hairy vetch. Care should be taken not to delay the date of seeding, since a vigorous and competitive cover crop is your best weed control. Hairy Vetch Vicia villosa Roth. Seeding Depth: 3/4” - 1 1/2” Seeding Dates: 30-40 days before the first killing frost in the fall, or as soon as ground can be worked in the spring A mixture of oats and hairy vetch. Seeding Rate: 60 lbs/A. The small grains also provide mulch that is more resistant to decomposition and contributes to the buildup of soil organic matter. The small grains provide a quick cover, whereas the hairy vetch grows slowly in the fall. ½ - 1½ . Item Number. Planting at a seeding rate that is too high increases seed costs and wastes money. However, attention needs to be paid to the herbicide program used; check the rotational restrictions on the label or in the Penn State Agronomy Guide . ft Seed Planting Depth: Broadcasting directly and lightly tamp into soil Treatment. Ideal seeding depth: ½–1½". Seeding rate. The C/N (carbon-to-nitrogen) ratio of the residue tends to be lower if the small grain is grown in companion with hairy vetch, contributing to faster decomposition of the small grain residue and less nitrogen immobilization. Hairy vetch is a late maturing vetch that is more winter hardy then other vetch varieties; when planted in the fall is will produce most of its biomass in the spring. 60°F. If volunteer small grain cannot be counted on, then it is recommended to seed a hairy vetch/small grain mix instead of pure hairy vetch. Download PDF New release from SARDI Vetch Breeding Program. Hairy vetch can fix large amounts of nitrogen that are released rapidly after it has been terminated. Later establishment will usually lead to a poor stand due to winterkill. The plant is sometimes planted in spring, especially in agricultural applications. Entering your postal code will help us provide news or event updates for your area. Seeding Rate: 30 lbs. The optimal seeding rate is 15 to 20 kg ha −1 in Massachusetts, New York, and Pennsylvania. Plant hairy vetch with grains if you intend to harvest the vetch for seed. Use seed that has been inoculated with the appropriate rhizobium strain (hairy vetch/pea group Rhi-zobium leguminosarum biovar viceae) to guarantee nitrogen fixation. Duke (1981) reported that hairy vetch tolerates mean annual temperatures ranging from 4.3-21.1 C, with a mean of 42 cases of 12.0. Decomposition and nitrogen release rates are faster if the vetch is incorporated, but total amount of nitrogen released over the entire growing season is similar to vetch left on the surface as a mulch. Austrian Winter Peas – Some plants may survive winter, good N production, mix with annual ryegrass or radish. If using a chisel plow, it is recommended to shred the vetch using a tool such as a flail mower before plowing.
