Cooperative Extension is based at North Carolina's two land-grant institutions, 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). Terminate before seed production to avoid hard seed Reseeding usually will not work for crimson clover planted before full-season field corn because crimson clover seed matures after corn planting dates. Rye cover crop terminated by a roller-crimper prior to planting certified organic soybeans. Management to achieve sufficient cover crop biomass entails planting in September or October and killing about April 1 in the east and in mid- to late April in the piedmont and mountains. 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. Management decisions such as the date and method of killing a cover crop influence the amount of cover crop growth and nutrient uptake, as well as the availability of the nutrients released to a following crop by decomposition. Hairy vetch is better adapted to more sandy soils and to more poorly drained soils than crimson clover, although crimson clover provides adequate dry matter production on most well-drained sandy loams. Broadcast the seed over the soil at the rate recommended on the seed package – usually 1 to 2 pounds of seed for every 1,000 square feet of garden space. This earlier seed set provides a good food source for some game birds and flowering to attract beneficals. 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. Individuals who use agricultural chemicals are responsible for ensuring that the intended use complies with current regulations and conforms to the product label. Harvest the seed as soon as the plants, pods and seeds are dry enough to thresh. A. Kranz. Most of those who have incorporated legumes into their farm management plans are small growers or farms using organic production methods. For this reason, in milder climates it is not as vigorous as other vetches but can still give high yields if allowed to fully mature in late May. Figure 6. Cultipacking after broadcasting will encourage good soil/ seed contact. N.C. For example, when cereal rye and hairy vetch are planted together, the rapid germination and early fall growth of cereal rye help stabilize the soil surface and allow the more fragile hairy vetch seedlings to thrive. The use of a starter fertilizer will ensure faster initial growth. Surface residue (from a cover crop or previous crop) helps conserve soil moisture during the spring/summer growing season by reducing water evaporation from the soil surface before the protective full crop canopy has been established. In strip tillage systems or with banded herbicide applications, a crimson clover cover crop can be managed so that a proportion of the stand is allowed to continue growing and produce viable seed. Using a small grain cover crop for silage or hay will greatly delay corn planting and thereby increase the risks of drought, heat stress, and pests associated with late planting. Depending on the grass and legume cover crops chosen, a reduction in seeding rate may be appropriate. Allowing the cover crop to grow until later in the spring will improve nutrient accumulation in the cover biomass, but it may reduce the ability of microbes to decompose residues for short-term use. For best results, plant 3-6 weeks prior to the average first killing frost. Anderson, J. R., N. L. Hubbard, F. D. Shaw, and F. W. Smith. For pasture: A field of fall-seeded rye and vetch can be pastured from early May through June, then plowed and sown... 3. On coastal plain soils, supplemental N (25–35 pounds per acre) may be needed to obtain adequate top growth. Seed crimson clover at 20 to 25 pounds per acre broadcast and 15 to 20 pounds drilled. Even if economic factors do not favor the use of legume cover crops to supply N, farmers may be interested in building organic matter, enhancing available soil moisture, and benefiting the complex ecosystem effects that are often associated with legume and grass cover crops. Limited research indicates that these soils respond to subsoiling even with the presence of a cover crop mulch. Corn yields in the piedmont are lower after small grain silage removal compared to leaving the small grain as mulch. One exception is on coastal plain soils that are responsive to in-row subsoiling. Rye is the easiest small grain cover crop to control with Gramoxone. Careful management can prevent this problem. Do note that a cover crop depletes soil moisture during active growth, and it may be difficult to obtain adequate corn stands during dry spring seasons. A wide range of planting dates exists for most legumes (Table 1), although early plantings obtain the best results. In addition, the potential for conserving soil moisture may be reduced if the cover crop is removed for silage, leaving less mulch and reducing the following corn yield (Figure 8). Variation in soil temperature at 2" depth with selected cover crops. Figure 3. A large seed, so it must be sown at a robust rate, to get a decent cover in the field. Thus, they can reduce crop growth unless sufficient inorganic N is applied (Figure 2). However, situations occur that make weed control very difficult under no-till management. This vetch has been observed to produce more biomass than many other vetches and fixation of N could even start within a week of emergence. Ideal Sowing Time They then harvest the forage for hay or silage. A&T State University, in all 100 counties and with the Eastern Band of Cherokee Use seed that has been inoculated with the appropriate rhizobium strain (hairy vetch/pea group Rhizobium leguminosarum biovar viceae) to guarantee nitrogen fixation. NC State University and NC Receive Email Notifications for New Publications. 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 This surface mulch enhances summer rainfall infiltration, reduces soil water evaporation, and provides weed control by early shading. Drilling depth can be up to an inch lower, if planted early but if broadcasting is the method used than a shallow incorporation is suggested. Cover crop growth can be terminated by tillage, rolling, or herbicides. Figure 2. This seed is then naturally dispersed and can germinate late in the summer when moisture becomes sufficient. commitment to diversity. 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. If carefully managed, hairy vetch may be grown with Bermudagrass. N.C. Crown vetch, a perennial, spreads by rhizomes under ground as well as by seed dispersal. While there is limited experience with this practice in on-farm situations, it is a viable option for innovative farmers. Successful stand establishment generally can be obtained with planting dates later than those for legumes, even as late as early December in coastal plain regions (Table 4). 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. seed will mature, but care must be taken to insure Smith, F.S., A.D. Falk, and W.R. Ocumpaugh. The forage produced is palatable when green but palatability will greatly increase as it's dried down. Harvesting can be made easier if the seed crop is sown with 10–15 kg oat seed/ha. Other management factors in a no-till system are similar to practices used with conventional tillage. The use of brand names and any mention or listing of commercial products or services in this publication does not imply endorsement by NC State University or N.C. A&T State University nor discrimination against similar products or services not mentioned. Leaving the cover crop on the surface also reduces its decomposition rate compared to plowing. To plant hairy vetch, plow the soil as you would for any regular crop. Cooperative Extension prohibits discrimination and harassment regardless of age, color, disability, family and marital status, gender identity, national origin, political beliefs, race, religion, sex (including pregnancy), sexual orientation and veteran status. Some producers may find the late maturity of WinterKing reduces the potential for undesired seed propagation found in earlier maturing cover crop varieties. Results of N response test for corn yields, Tyrrell County, 2007. Killing the cover crop about 10 days before planting no-till sorghum or vegetables can minimize soil water depletion. Growers need to consider timing when planting winter wheat in locations where the Hessian fly may be a problem. Raleigh, NC: Agricultural Experiment Station, North Carolina State College. The next spring, the cereal rye plants provide physical support for the climbing hairy vetch stems. This vetch has been observed to produce more biomass than many other vetches and fixation of N could even start within a week of emergence. For Austrian winter pea, the rates are 25 to 35 pounds per acre broadcast and 20 to 25 pounds drilled. Woollypod vetch has been observed to survive conditions as low as 0 degrees F with no snow cover but that was without much fluctuation in the temperature. Timely management is required to optimize cover crop and cash crop performance. Aerial overseeding into cotton at defoliation or into soybean prior to leaf drop has been successful in some cases (Figure 7). The nonlegumes rye and triticale provide maximum erosion protection during fall and winter because of their rapid growth rates. What puts vetch in the weed category is that the hairy vetch, an annual, drops its seed early and once established it’s very difficult to eradicate. Recommendations for the use of agricultural chemicals are included in this publication as a convenience to the reader. It can also be used in feed as hay, silage or grazing due to its high crude protein content. SmartMix is the best cover crop decision making tool in the industry. B: Cover crop wheat planted to protect a planned summer vegetable crop. Planting about a quarter of your garden to cover crops each year can add fertility, reduce erosion, help break pest cycles, and much more. In many areas of North Carolina, nutrient management is becoming increasingly important as farmers do their part to protect surface waters from nutrient loading. All of these plants have similar heights, so deleterious shading would be at a minimum compared to using taller rye and shorter crimson clover. * 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). If the legume cover crop is established early enough, adequate growth in the fall can help minimize soil erosion. For certified organic farms, non-manure N sources often cost several dollars per pound of N, and legume use is usually cost-effective. For sandier coastal plain soils, such as Wagram, Lucy, Kenansville, and Conetoe, rye is the preferred small grain cover crop. Raleigh, NC: N.C. Determine small grain lime and fertilizer needs based on soil test results. B: Water erosion on sloping land. Winter Cover Crops: Their Effects on Corn Yields and Soil Properties. Using no-till planting and cover residue can increase the reservoir of available soil water and can substantially increase corn yields in droughty years. When to Grow Crown Vetch?. Hairy vetch is not a crop that would planted as a monoculture if your goal is to build organic matter. If Hessian fly is present in your area, wheat should be planted after the first fall frost. Either Gramoxone Super or Roundup can be used to control existing cover crop vegetation. Decomposition of legume residues proceeds rapidly under favorable conditions, and most of the N becomes available before the corn tassels and silks or by the time it is needed by grain sorghum or most short-season vegetable crops. Therefore, use of a soil insecticide is recommended when planting without tillage into a cover crop. Common vetch, Vicia sativa, does not produce as much seed as hairy vetch, posing less of a risk of becoming weedy. The legumes best adapted to North Carolina soil and climatic conditions are crimson clover, hairy vetch, Austrian winter pea, and Cahaba white vetch. Woollypod vetch has the potential to grow faster and earlier than hairy vetch. This thick thatch will slow soil warming and drying and this could cause some issues in a no-till system. Spray solutions for Gramoxone can be water, nitrogen solution, or clear fertilizer solutions and must contain a nonionic surfactant. Figure 1B. Technical Bulletin no. Hairy vetch develops best under cool temperature conditions on fertile loam soils; it is also productive on sandy or clay soils. 10% - 30% vetch inclusion in a whole crop mixture with cereals and or peas. For this reason, fertilizer N application rates should reflect both cover crop and summer crop potential constraints, with attention being given to timing and placement of fertilizer N to promote high yields (Table 6). Hairy Vetch. In general, planting late (late October to November) in the piedmont and mountains will increase the risk of winter kill. Handbook series book 9. Surface residue cools the soil considerably during the spring, with late-summer differences between the cover and bare soil lessening as the corn crop begins to shade the soil. Winter annual cover crops can be either legumes or cereals. A Florida based worldwide supplier of Lawn, Pasture and Turf Grass Seed at wholesale pricing direct to the public! Growing Organic Hairy Vetch Cover Crop Garden Seeds. Woollypod vetch can be easily grown if planted into a moist soil, in the early fall. The following general cultural practices are applicable to all legume cover crops: Planting dates. Managing Cover Crops Profitably. In addition to protecting land from erosion, hairy vetch can provide spring pasture for livestock. No-till planting into a cover crop involves minimal soil disturbance—that is, opening only a narrow furrow for the seed. AU Merit hairy vetch can be seeded at a rate of 10-40 lbs/acre depending on the mix or purpose. It has been reported to grow … The procedures for planting without tillage into a cover crop are similar to planting into residues of a previous crop, such as soybeans or corn. In some instances, the effectiveness of both Gramoxone and Roundup on actively growing legumes has been enhanced by the addition of 2,4-D amine (1⁄2 to 1 pint per acre) or Banvel (1⁄2 pint per acre tank-mixed). Hessian fly does not inhabit rye, triticale, barley, or oats. Hairy vetch has consistently performed well in these trials, and crimson clover is also promising on well-drained sites (Figure 2; Table 3). As an annual legume, hairy vetch may need to be terminated either mechanically or chemically when followed by a row crop. 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). With a very low C:N ratio the residue breaks down very quickly and will leave the soil bare throughout much of the growing season. Hairy Vetch is best grown with plants like cereal rye that enable the hairy vetch to climb up the cereal rye to allow air movement across the soil surface. Cooperative Extension. Be notified by email when this product is back in stock. In other cases, producers plant it with winter annual grasses, especially small grains. 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. When grown for hay, vetch is generally cut when the first pods are set. Freeze damage has also occurred with Austrian winter pea in higher elevations (above 2,500 feet). Latin Name: Vicia villosa Common Names: Winter Vetch, Fodder Vetch, Sand Vetch Hairy Vetch Hardiness Zones: Perennial to zones 1-7, Annual cover crop Days to Maturity: 80-90 days (longer when left to germinate over winter) Hairy Vetch Seeding Rate: 1-2 lb per 1000 sq. Mixture Sowing Rate Advice. It grows slowly in the fall, but its roots grow throughout the winter and by spring, hairy vetch quickly grows into twelve-foot long vines. Vetches have the ability to offer substantial improvements in soil fertility, structure and organic matter as well as offering a weed and disease break for cereals in a crop rotation. 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. I. Corn growing in a hairy vetch cover crop after herbicide has killed the vetch. The oat seed is readily graded out of sample and the oat plant provides a framework for the twining, usually prostrate, vetch. When the summer crops are grain sorghum or warm season vegetable crops, planting dates can be more flexible. With hard seed potential, seed can germinate over the course of several years and this would be a concern in fields that will be planted to a commercial cereal grain crop. For corn following a small grain cover crop, special consideration must be given to fertilization, especially with regard to the N source, placement, and timing of application. This method will work in North Carolina where the following crop is midsummer vegetable crops (pumpkins), grain sorghum, or tropical silage corn (late spring establishment). Cooperative Extension county center. Higher seeding rates and sowing in nutrient deficient fields can aid Woollypod vetch in weed suppression. For both hairy vetch and Cahaba white vetch, the rates are 20 to 30 pounds per acre broadcast and 15 to 20 pounds drilled. One solution is to consider planting fields with legume cover crops last and to monitor early spring conditions to minimize moisture depletion before corn-planting time. 7.5 - 22.5kg per acre / 18.75 - 56.2 kg per ha. Read our Timing is particularly important with legumes because late seeding results in small plants with limited root systems. Hairy vetch is a hardy type of vetch suited to wetter soil and colder winters than other winter-active legumes. Corn is highly sensitive to moisture stress at critical stages of development. Sustainable Agriculture Network. — Read our Generally, a grass species is combined with one or more legume species. If a legume cover crop contributes 100 pounds of N/ acre, the legumes would cost the equivalent of a typical inorganic N fertilizer (30% N as UAN solution) priced at $275 to $450/ton for crimson clover and hairy vetch, respectively (Figure 9). 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. Get ratings for species suitability based on goals, planting dates, geographic location C:N ratio, nitrogen fixation, grazing suitability, frost tolerance and more. It has very high feed values for animals as green plants and dry matter as well as grain. Figure 10. As previously discussed, seeding depth varies from 1⁄2 to 11⁄2 inches, depending on soil texture. Seed corn insects can be abundant in cover crops used as no-till mulch. Being a very versatile vetch, it can grow in many types of soil conditions including even poor fertility or sandy soils. In the spring, if grazing continues too long, growers may find that the rough soil conditions caused by hoof traffic lessen the benefits they expected from spring no-till management. Also, early-planted row crops and spring-planted vegetables tend to grow more slowly under mulched conditions because of lower soil temperatures. 2. D: Wheat cover crop on Caroline fine sandy loam, 2%–6% slopes. Aerial seeding of rye into soybeans just before leaf drop has been marginally successful. When planted alone as a winter cover crop in annual vegetable rotations, it can provide as much as 110 lbs. Crimson clover productivity has been much lower on poorly drained soils, with N accumulations of less than 25 lb/acre in some recent field trials. With a small grain cover crop, killing it seven to fourteen days before corn is planted can reduce potential soil water depletion. For assistance, contact your local N.C. If planted in the spring, weed competition could be an issue and the vetch should be allowed to grow to at least memorial day to justify your investment. May have some allelopathic properties, so it is best to allow 2-3 weeks between incorporating and seeding of small-seeded crops. If planted to late when soils start to cool off than overall germination and results will be unfavorable. 1 = Poor : 5 = Average : 10 = Excellent. of nitrogen per acre to a following spring crop. Hairy vetch can become weedy if left to produce seed. Because Cahaba white vetch does not possess much winter hardiness, it is not adapted to the western regions of the state. Remember, though, that late seeding dates may sacrifice some soil erosion protection. Kamprath, E. J., W. V. Chandler, and B. Figure 8. Mow the hairy vetch before the plant flowers in spring. Woollypod vetch can be more sensitive to cold weather fluctuations than some other vetches. Cover crops in a conservation tillage planting system provide erosion control during the winter while the plant is growing and mulch for the soil surface during the summer in the form of crop residue. This allows establishment of the cover crop after a late-fall-harvested crop such as soybeans. Cover the seeds with about ½ inch of soil, then water well. Seeding rate, depth, and method. Raleigh, NC: Proceedings of the 1990 Southern Region Conservation Tillage Conference. When allowed to overwinter, the extra growth aids in smothering out weed competition and protecting the soil. 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. There are other types of vetch plants, but hairy vetch is most widely used in farming. Hairy Vetch is a viney, cool season legume best used in a crop rotation for erosion control or as a cover crop. C: Cotton strip-till planted into a wheat cover crop on Augusta fine sandy loam. Proper field scouting is important in determining the need for postemergence weed control measures. 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). Seeding rates are 1 to 11⁄2 bushels per acre for rye, triticale, and wheat and 2 bushels per acre for oats. For corn and cotton, the generally lower soil temperature under the cover crop makes it imperative to select a hybrid that demonstrates excellent germination and seedling vigor under cool, wet conditions (Figure 10). However, in a hairy vetch cover crop, increased populations of soybean cyst nematodes have been found. Several studies comparing conventional and no-till corn in eastern North Carolina have documented the potential contribution of N by legumes. If not given structure to climb, Woollypod vetch with grow across the ground forming a very thick and tangled thatch. Growth correlates with growing degree days (units of average daily temperature compared to a base at which no growth takes place) which are calculated for hairy vetch using a base temperature of 4° C (39.2° F). Publication date: May 6, 2014 Overseeding can avoid the reduced productivity that might result if planting is delayed until after harvest of certain crops (Table 3). If grown as a seed crop, hairy vetch is harvested when the lower pods are ripe to avoid shattering. ft Seed Planting Depth: Broadcasting directly and lightly tamp into soil Effect of cover crop and N rate on corn grain yield (2-year average). Soybeans are never harvested early enough for the seeding of legume cover crops. Although crimson clover, hairy vetch, Austrian winter pea, and common vetch are widely adapted to soil and climatic conditions in North Carolina, they do have some limitations. Indians. Hairy vetch is a winter annual legume and one of the most productive at nitrogen fixation. When growing a winter rye and legume mixture, the rate of winter rye seeding should be reduced to no more than a bushel per acre to allow space for the legume to grow. Two or more cover crop species can be combined in a single planting to realize the benefits of each. In planting, use shallow planting depths for finer-textured, clayey soils and deeper depths for coarse-textured, sandy soils. An innovative system that has shown promise in other southeastern states is to allow crimson clover to reseed itself naturally. Call to Order: We are encouraging our customers to call us at 800-352-5247 to place your orders.We can then ship your seed directly to you, or you can come pick it up at Albert Lea Seed. Cover crop residue usually does not promote a higher population of nematodes in no-till corn. Recent trials have also included lupines, berseem clover, subterranean clover, and other legumes. ft Seed Planting Depth: Broadcasting directly and lightly tamp into soil The cover also decreases rainfall runoff and increases water infiltration. All these potential benefits are highly dependent on weather and management factors that should be considered when using cover crops. Growing Hairy Vetch Cover Crop Garden Seeds. It may be cut using a mower with a swather attachment. Strip-plantings of cereal rye can also be used as windbreaks to protect vegetable crops and tobacco from wind erosion (Figure 4). With the early harvest and the open fall this year, there is enough time for a cover crop to be seeded and to have adequate growth to provide some benefits. 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. When cereal rye is planted early in the fall alone and in mixtures, it can greatly reduce available soil nitrogen that can be subject to leaching during the wet winter months. This vigorous, fast-growing perennial grows in 2-foot tall mounds. Seeds that have a hard seed coat can lay dormant in the soil for over five years. The plant will grow vigorously throughout the winter. When hairy vetch, common vetch, crimson clover, and Austrian winter pea were planted in a mixture with cereal rye, spring oats, or winter wheat, the cereal rye/hairy vetch mixture had 30 to 45 percent less residual inorganic soil nitrogen than legume-only plots.
