This increased rate helps to compensate for the more extreme conditions that the seedlings are likely to weather during emergence and the earliest and most vulnerable stages of growth. �w���bS�w�1Z��8p�H�� Farmers on the northern plains often have to contend with snowy, icy, or muddy conditions well into the spring, which interferes with timely planting of the year’s crop. Vetch’s optimum germination temperature range is 15° to 23° C (59° to 73.4° F). Dormant seeding is indeed a risk, and like any other planting event it takes careful planning and attention to weather patterns. View our financial After emergence, the seedlings begin to grow before the frost, form a crown (indicated by several secondary shoots from the base of the main stem), and then use stored root carbohydrate reserves to survive dormancy over the winter. 0000003548 00000 n Our trial was quite unusual, because we took this practice and applied it to a winter annual, in effect shifting and condensing the vetch’s life cycle to fit our rotation. The leaves have long, soft hairs with 10 to 20 leaflets borne opposite each other and tendrils at the end. It’s (Almost) Never Too Late to Plant Hairy Vetch, Rodale Institute’s Farmer Training (RIFT), Influence of Alternative & Conventional Agricultural Management on Soil Microbial Processes & Nitrogen Availability, Monitoring the Decline in AM Fungus Populations & Efficacy During a Long Term Bare Fallow, Field Guide: Controlling Striped Cucumber Beetles with Insectary Strips. If farmers miss the critical window for planting hairy vetch (typically 40 to 50 days before the first killing frost, or mid-August to mid-September here in Berks County, Pennsylvania), the data shows that dormant seeding may be their next best bet. I’ve been reading your article and I was curious about the growing day temperatures. Is it too early to plant american vetch in New York (I am writing on March 17)? The vetch begins to grow again in earnest early the following spring. and consumer education. Ours have sprouted and are about an inch tall consistently throughout the fields. 0000004406 00000 n For transplanting tomatoes into hilly, erosion-prone soil, Steve Groff fall-seeds a per-acre mix of 30 pounds rye, 25 pounds hairy vetch and 10 pounds crimson clover. Sow in the spring as part of a whole crop mixture, but can be autumn sown for over winter cover or grass silage mixes. When hairy vetch is sown in late July or August, the seed germinates readily and the plants generally form a crown before the first snow. Erosion control/Cover Crop: Hairy vetch provides good ground cover for erosion control during winter and spring. Broadcast With Light Incorporation: 17 – 22 lbs. When used as a winter-annual cover crop and planted during this window in early fall, hairy vetch puts on preliminary growth, goes dormant in seedling form over winter, and blooms the following spring. 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). It is best used in mixtures with cool season annual grasses and clovers. This taproot will allow the vetch to thrive even in dry conditions. Since temperature had a strong influence on germination, seeding time for some legumes should be selected to match expected temperatures for particular locations. The mixture should be sown several weeks before the typical first fall frost date to allow time for the legume to adequately establish so it can survive the winter. For best results, plant 3-6 weeks prior to the average first killing frost. View our financial It is therefore vital that dormant seeding be followed by a consistently cold winter. A seeding rate of about 20 to 30 pounds of hairy vetch per acre is recommended. Although it will not provide winter ground cover (we made up for this by planting into residue), it provides a sound alternative to spring planting. 0000002780 00000 n Minimum Germination Temp: 60 ℉. Learn how your comment data is processed. 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. Despite the deceptive warmth, growing hairy vetch as it was destined to grow—as a winter annual—would have been risky business. However, seed germination rates of three species were influenced by priming: 50% germination was reached 8, 6, and 9 h earlier in hairy vetch, mustard, and perennial ryegrass, respectively. Hairy vetch is valuable for use in no-till systems. per acre. per acre. With a little creativity, hairy vetch can be worked into almost any rotation, and it’s well worth the effort for the soil enrichment, fertility and weed suppression it provides. The corn would need not only an ample amount of nitrogen from the vetch but also plenty of dense biomass for weed suppression. Successful dormant seeding requires that farmers get seeds in the ground before the ground freezes and winter-long snow cover arrives, but not so early that warm weather coaxes a tender sprout from the ground to face the violent elements of winter before it has a chance to put on adequate growth and energy reserves for survival. Genevieve Slocum and Dave Wilson. 0000003908 00000 n Crown vetch is an extremely aggressive perennial that is used for erosion control, not as a cover crop. sk�S��I@ou�X A heavy Crude protein content of AU EarlyCover is about 27 percent on April 1. 0000006929 00000 n %PDF-1.4 %���� Wendy, Hi, I live in southern Indiana, zone 6a and we planted hairy vetch October 10. The ideal temperatures for early root growth range from 20° to 25° C (68° to 77° F). Hairy vetch (Vicia villosa) is a legume that's related to peas and beans. Dave Wilson, my supervisor at the time and encyclopedia for all things agronomic, got the idea for dormant seeding from hearing stories of farmers in North Dakota who used the practice to get a head start on planting spring wheat, since conditions for driving a tractor in a northern spring can be quite tricky, often excessively wet and muddy. endstream endobj 134 0 obj<>stream Buy now Tech Sheet Tech Sheet (Spanish) It has been reported to grow … Maturing earlier in the spring than hairy vetch allows this species to reach its maximum N production sooner. 119 31 of nitrogen per acre to a following spring crop. 0000007789 00000 n 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. We increased the seeding rates for the dormant- and spring-seeded vetch, from the fall rate of 27 lbs/acre to 33.5 lbs/acre. 0000000933 00000 n information. Inoculant: Pea-Vetch or Garden Combination inoculant (sold separately) Germination: 5-10 Days; Plant Height: 2 - 3' Use: Green manure, weed competition, erosion control; Facts to Note: Tolerates cold temperatures if well established When the seed does germinate, it depletes its energy reserves, and is unlikely to survive prolonged periods of freezing once its first shoot emerges. Duke (1981) also recounted briefly the history of hairy vetch breeding and seed production in the U.S. 0000006092 00000 n The goal was to follow the vetch cover crop with a no-till corn crop, ideally planted into the rolled vetch mulch. x�bb�g`b``�� �)7 A dormant seed should be just as the name implies throughout the cold months—asleep and inactive beneath soil, residue and snow. 0000009665 00000 n endstream endobj 120 0 obj<>/Metadata 19 0 R/PieceInfo<>>>/Pages 18 0 R/PageLayout/OneColumn/OCProperties<>/StructTreeRoot 21 0 R/Type/Catalog/LastModified(D:20061002112745)/PageLabels 16 0 R>> endobj 121 0 obj<>/PageElement<>>>/Name(HeaderFooter)/Type/OCG>> endobj 122 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/ExtGState<>>>/Type/Page>> endobj 123 0 obj<> endobj 124 0 obj<> endobj 125 0 obj<> endobj 126 0 obj<> endobj 127 0 obj<> endobj 128 0 obj[/ICCBased 142 0 R] endobj 129 0 obj<> endobj 130 0 obj<> endobj 131 0 obj<> endobj 132 0 obj<> endobj 133 0 obj<>stream Hi Amber–great question! 0000073601 00000 n 0 The idea behind dormant seeding is to plant when it’s cold enough to inhibit the seed’s germination so that it lies dormant over winter and is ready to germinate when the ground first begins to thaw—but is still too wet to drive through. Purple flowers form in early to mid summer. The leaves of hairy vetch are oblong, with 5-10 pairs of leaves per leaflet. This means that hairy vetch should be terminated after May 1 in southern Pennsylvania, after May 10 in central Pennsylvania, and after May 20 in northern Pennsylvania and higher altitudes. 0000025657 00000 n 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. Ideal Sowing Time. 0000005154 00000 n It turns out that dormant seeding is a feasible Plan B. But it is probably better than nothing for the farmer who missed their ideal fall seeding window. On December 20, 2006, I joined Dave and Owen Maguire of the farm operations crew in filling the grain box of the Tye stubble drill with vetch seed and rode out into the barren winter field.

He likes how the threeway mix guarantees biomass, builds soil and provides N. Spring seeding. Ideal seeding depth: ½–1½". Thank you for your feedback. If planting with clovers, seed rye at a slightly higher rate, about 56 lb. To fix much nitrogen, the hairy vetch should not be terminated too early in the spring (Table 1). Crimson can grow at lower temperatures better then almost any other clover species. Rodale Institute is a 501(c)(3) nonprofit. Being more winter hardy than common vetch, hairy vetch has the potential to withstand temperatures in excess of 5F with no cover. By the time the weather's warm enough to plant tomatoes, it will be three to four feet tall and beginning to flower. trailer Thanks for reading! AU EarlyCover also is a better choice than common hairy vetch for forage purposes for producers who want to provide early spring grazing for livestock. The flowers are small but I think they're showy. 0000001237 00000 n If farmers miss the critical window for planting hairy vetch (typically 40 to 50 days before the first killing frost, or mid-August to mid-September here in Berks County, Pennsylvania), the data shows that dormant seeding may be their next best bet. A later planting date means increased probability of temperatures dipping below these ranges, which means less likelihood that plants will grow enough to conduct adequate energy reserves, through photosynthesis, into their root storage systems. startxref Germination is once and done forever, the seed’s instinctual flying leap from the safety of dormancy to inject its new life into the world. Legume choice (vetch vs clover), but also the variety of that legume (‘Lana’ vetch vs hairy vetch) Cover crop planting time (where earlier planting can increase nitrogen release the following year) Cover crop termination time; Current soil nitrogen levels; Seeding rates; Single stand vs. mix; Carbon:Nitrogen (C:N) ratio of the cover crop Drill: 15 – 20 lbs. They are annuals that can easily be killed when time comes to plant the main crop. Peak N production occurs during flowering around the middle of May when it is induced by 12 hours of daylight. And if it is okay, should I soak the seeds in warm water for 24 hours prior to planting? 0000003119 00000 n 0000073862 00000 n Hairy vetch, winter vetch, woolly vetch Uses Range Improvement: Woollypod vetch is particularly ... be treated with a fungicide at the time of planting. and 15 to 20 pounds of vetch per acre should be used. 0000015012 00000 n Plant vetch 30 to 45 days before killing frost for winter annual management.

I am curious if they will continue to grow as long as the day temperatures stay above 50 F, which is what we are experiencing now. Because of its sprawling, viney growth habit, hairy vetch can suppress late winter/early spring annual weeds. Ideal temperature for germination is about 68 degrees F. If the soil temperature is too cold, the seed will not germinate. This species is known to have a great rooting system, with a tap root that will extend 1 to 3 feet into the soil profile. Management Hairy vetch performs well in rotations with conventional and no-till planted row crops. In southern Illinois, hairy vetch no-tilled into fescue provided 40 to 180 lb. Hairy vetch, as a winter annual, will sprout in the fall, overwinter, regrow in spring, go to seed and die. However, seed germination rates of three species were influenced by priming: 50% germination was reached 8, 6, and 9 h earlier in hairy vetch, mustard, and perennial ryegrass, respectively. 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. Planting about a quarter of your garden to cover crops each year can add fertility, reduce erosion, help break pest cycles, and much more. vtt4�5 +�a+��bU�� In spring, the plant produces 3 to 10 long, weak, branching stems or vines 3 to 6 ft long. In the southeastern U.S. early cultivars like ‘AU EarlyCover’ can produce three times the dry matter in February as a late maturing hairy vetch. 0000004649 00000 n FR����]Q��aV7� WinterKing hairy vetch can be seeded at a rate of 10-40 lbs/acre depending on the mix or purpose. The more time your mix has to grow, especially during the summer, the more options you have for diverse species. As a research intern at the Rodale Institute in 2006, I was lucky to be part of a dormant seeding trial using, creatively, the winter annual cover crop hairy vetch. %%EOF Results from the 2006-2007 trial, however, showed us that farmers would almost certainly be better off using the dormant seeding approach, with all its risks, rather than waiting until spring and gambling on potentially un-plant-able fields to seed the vetch in time. Rodale Institute is growing the organic movement through research, farmer training, Do not include brassicas or hairy vetch, because October 15 is past their optimum planting time (see the Midwest Cover Crop Council website below for further reading). The answer was yes and no. In stands where it occurs, a one year rotation with another crop will generally destroy the residue which harbors the pathogen. Website by Infantree. English photo. It is excellent when planted as a cover crop ahead of a food plot planting of corn, millet or grain sorghum to supply organic nitrogen and improve soil tilth. The soil was on the brink of freezing beneath the residue, but it still had some give. 149 0 obj<>stream Hairy vetch develops best under cool temperature conditions on fertile loam soils; it is also productive on sandy or clay soils. The scientists sowed the vetch in mid-September. by No-till corn into killed vetch. This field is for validation purposes and should be left unchanged. Fall temperatures during the experiment year were warmer than usual, so many time-strapped farmers were calling Dave in October to ask if they could still plant hairy vetch. Hairy vetch is one of the most winter hardy legumes. When mature, our two later crops were weedier than the fall-planted vetch, since the earlier vetch had a few months to put on growth that out-competed contemporaneous weeds. Germination: 10 - 14 days. Crown vetch seeds germinate best in soil that is between 68 and 77 degrees Fahrenheit.

Warm mid- to late-fall weather can support hairy vetch emergence and early growth, but these hospitable temperatures can plunge without warning, leaving vulnerable seedlings with too little biomass and insufficient energy supplies left to withstand brutal weather. With an overall rate of 75 kg per acre / 187.5 kg per ha. The best time for planting no-till corn into hairy vetch varies with local rainfall patterns, soil type, desired N contribution, season length, and vetch maturity. The leaves have 12 to 20 leaflets and terminate with tendrils. Soil Preference: Till soil so that after seed is sown, seed can be raked into the top 1/4" of finely worked soil. endstream endobj 148 0 obj<>/Size 119/Type/XRef>>stream However, neither dormant seeding nor spring seeding is likely to yield enough biomass for an effective weed-suppressing mulch in a no-till system. 0000004905 00000 n 0000011572 00000 n per acre. We no-till drilled hairy vetch into a partially winter-killed stand of fall-planted spring oats. 0000005231 00000 n Following a dormant seeding, the seed’s metabolic activity will be low, preventing it from germinating, if temperatures remain below 35° F. Once the seed’s temperature reaches 38° F to 40 °F, with sufficient moisture, germination begins. ���/M�@*�;%����̃���?� ����:�f��B� BĄ���nt� As temperatures gradually warm and days lengthen, seeds begin to absorb moisture, and the new seedlings grow rapidly as growing degree day units increase. We suggest you reach out to our Organic Crop Consultant Sam Malriat (Sam.Malriat@RodaleInstitute.org) with your questions. Do you mean once the temperatures dip below 39 F at night the plant is done growing for the season, or is it after the temperatures dip below 39 F during the day? Emergence Time: 14 days. The flowers, borne in a dense one-sided spike, are violet and white to rose colored. Hairy Vetch is the go-to crop when nitrogen production is at the top of your list for goals to achieve. 0000008715 00000 n 0000002253 00000 n xref For example, a planting date of October 15 will be good for cereal rye, winter wheat and triticale. Hairy vetch (Vicia villosa) is a trailing winter annual, biennial, or summer annual weed that forms large mats of vegetation. information. Thank you, The plants flower 23 to 36 days earlier than commercial hairy vetch. For northern farmers who need a more winter-hardy vetch, look for a northern seed tag origin.
