A seeding rate of about 20 to 30 pounds of hairy vetch per acre is recommended. This vigorous, fast-growing perennial grows in 2-foot tall mounds. An innovative system that has shown promise in other southeastern states is to allow crimson clover to reseed itself naturally. There are many combinations to choose from: using winter wheat or cereal rye; planting flat or on beds; and planting the following crop no-till, strip-till, or conventional till. Strip-plantings of cereal rye can also be used as windbreaks to protect vegetable crops and tobacco from wind erosion (Figure 4). Cooperative Extension, College of Agriculture and Life Sciences, NC State University. By combining grass and legume cover crops, farmers also can gain the benefits of nitrogen scavenging, high biomass production to build organic matter, biological nitrogen fixation, and moderated nutrient release, compared to a legume-only cover crop. Planting Depth: 0.5-1.5 inches For both hairy vetch and Cahaba white vetch, the rates are 20 to 30 pounds per acre broadcast and 15 to 20 pounds drilled. Hairy vetch is a winter annual legume and one of the most productive at nitrogen fixation. Hairy vetch has consistently performed well in these trials, and crimson clover is also promising on well-drained sites (Figure 2; Table 3).

The forage produced is palatable when green but palatability will greatly increase as it's dried down. Variation in soil temperature at 2" depth with selected cover crops. No-Till Farm and Garden Cover Crop Mix Seeds - 1 Lbs - Blend of Gardening Cover Crop Seeds: Hairy Vetch, Daikon Radish, Forage Collards, Triticale, More Visit the Mountain Valley Seed Company Store 4.4 out of 5 stars 384 ratings Seeds that have a hard seed coat can lay dormant in the soil for over five years. In Figure 2, maximum yield was attained with both 104 lb fertilizer N/acre and with 54 lb fertilizer N/acre plus vetch; thus, vetch appears to supply the equivalent of 50 lb N/acre. Hairy vetch is not a crop that would planted as a monoculture if your goal is to build organic matter. Common vetches are an annual pasture/forage/grain legume, extremely palatable at all growth stages, from early green shoots, as dry matter/hay or silage through to seedpods and seeds over summer. 7.5 - 22.5kg per acre / 18.75 - 56.2 kg per ha. Cooperative Extension is based at North Carolina's two land-grant institutions, High pressure (40 to 45 pounds per square inch) will help the spray penetrate dense vegetation. Terminate before seed production to avoid hard seed 129. For both hairy vetch and Cahaba white vetch, the rates are 20 to 30 pounds per acre broadcast and 15 to 20 pounds drilled. Crown vetch, a perennial, spreads by rhizomes under ground as well as by seed dispersal. A wide range of planting dates exists for most legumes (Table 1), although early plantings obtain the best results. N.C. Aerial seeding of rye into soybeans just before leaf drop has been marginally successful. Seeding rates are 1 to 11⁄2 bushels per acre for rye, triticale, and wheat and 2 bushels per acre for oats. In Figure 9, prices can fluctuate dramatically, but current total production cost estimates are $60–$75/acre/year for hairy vetch, $45–$60/acre/year for seeded crimson clover, <$30/acre/year for self-reseeding crimson clover, $40–$60/acre/year for winter pea, and $300–$400/ton for an inorganic fertilizer with 30% N as a UAN solution.

A&T State University nor discrimination against similar products or services not mentioned. Killing the cover crop about 10 days before planting no-till sorghum or vegetables can minimize soil water depletion. This extra surface residue accumulation can benefit subsequent crops, but it should be evaluated to determine whether it inhibits crop growth or encourages pests or diseases. 4. Fertilizer costs vary due to market fluctuations but are generally in the range of $0.35 to $0.70/pound of N ($200 to $400/ton of 30 percent N solution). This seed is then naturally dispersed and can germinate late in the summer when moisture becomes sufficient. The following general cultural practices are applicable to all legume cover crops: Planting dates. Woollypod vetch has the potential to grow faster and earlier than hairy vetch. At a Wayne County site, the thin crimson clover cover stand on the left was planted late (November 19), whereas the plot on the right was planted as recommended on October 12. 2012. adequate seed drying procedures are followed to Notice of Release of Hoverson Germplasm deer prevent molding and heating of this mixture. With careful management, this system can work for full-season no-till corn if strips of crimson clover are allowed to mature, produce, and disperse seed (as discussed in the “Legume N Economics” section, below). Winter annual cover crops have been used in rotation with summer crops for many years in North Carolina, but now there are some interesting new applications of this practice. All these potential benefits are highly dependent on weather and management factors that should be considered when using cover crops. Residual weed-control methods for no-till crops planted into a cover crop are similar to those used for conventional planted crops, with the obvious exception of the use of cultivation for weed control. Ideal seeding depth: ½–1½". 10% - 30% vetch inclusion in a whole crop mixture with cereals and or peas. This allows establishment of the cover crop after a late-fall-harvested crop such as soybeans. In contrast, the presence of a cover crop, particularly rye, has had a beneficial effect on weed control by suppressing germination of many large-seeded broadleaf weeds. Active cover crop growth in the spring, before the summer crop is planted, offers continued erosion control compared to bare ground. Publication date: May 6, 2014 One or more residual herbicides are usually applied at the same time as the knockdown herbicide. Hairy Vetch does an excellent job in soil tilth in the top few inches in the soil, often creating the illusion of planting in a cloud due to the soil’s looseness. Legumes can supply much of the N required for many summer crops, from row crops such as corn or grain sorghum to vegetables such as sweet corn, cabbage, squash, and pumpkins (Figure 2). Positive yield responses in corn have been documented when planted after Woollypod vetch and there is no known hazards of increasing insect pest issues. This means using a spray volume of 20 to 60 gallons per acre for Gramoxone and 10 to 30 gallons of water per acre for Roundup. Studies have shown some tolerance to glyphosate. Caesar Kleberg Wildlife Research harvested with this method is best cleaned by Institute. Harvesting: 1. When allowed to overwinter, the extra growth aids in smothering out weed competition and protecting the soil. Aerial overseeding into cotton at defoliation or into soybean prior to leaf drop has been successful in some cases (Figure 7). Early experiments date from the 1940s and show several important benefits of planting winter annual cover crops, chief among them erosion control, addition of nitrogen (N) to the soil for use by a subsequent crop, removal of N from the soil to prevent nutrient loading, buildup of soil organic matter, and buildup of residue that acts as a mulch for water conservation or retention. Being a very versatile vetch, it can grow in many types of soil conditions including even poor fertility or sandy soils. Addition of a residual herbicide to the burndown herbicide also improves cover crop kill. The cover also decreases rainfall runoff and increases water infiltration. In general, planting late (late October to November) in the piedmont and mountains will increase the risk of winter kill. Mix with cereal rye for increased weed suppression and increased winter survival of hairy vetch; Soil health benefits: source of nitrogen, increases weed control; Slow-growing cover crop so seed early for best growth; Not a good option for grazing. * Dry matter and N accumulation were significantly reduced if planting was delayed until November following harvest of a maturity group 5 soybean (P<0.05). A well-established legume cover potentially can supply 50 to 150 or more pounds of N per acre, or approximately two thirds of the N required by a corn crop and most of what is needed for grain sorghum and some vegetable crops (Table 3 and Table 5). Hairy Vetch (Vicia villosa) is a short term legume commonly used for cover crops in home gardens, weed suppression, erosion control, ground cover, green manure, pasture, silage and hay.
