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. ;R�7��]-0 �w���`��8�Y�8��So�m�������o�gS?�P�3Z-h��IX��*gW�L[2��dF�� o%��=��-L̀��U�䉂5��>�؈C��`��{��T�'�~��P0I��2��~K�P�TG���"edc���v��c�䟺�������U��4��'�%�%���9�SN��;�Z"�-rkI�p�Tc���7.�e��.¶�CF���'E`a{�ݣs84��*3��49)���Y�u�e�h�`�����{z ���z�Cz� 0 ��� This taproot will allow the vetch to thrive even in dry conditions. Duke (1981) also recounted briefly the history of hairy vetch breeding and seed production in the U.S. The leaves have long, soft hairs with 10 to 20 leaflets borne opposite each other and tendrils at the end. 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. information. Minimum Germination Temp: 60 ℉. 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. English photo. 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. And if it is okay, should I soak the seeds in warm water for 24 hours prior to planting? startxref Without something to climb, vetch can reach heights of about one foot, but grows much higher with a form of support, such as a fence. 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. 0 For best results, plant 3-6 weeks prior to the average first killing frost. Dormant seeding is indeed a risk, and like any other planting event it takes careful planning and attention to weather patterns. Thanks for reading! 0000007789 00000 n But it is probably better than nothing for the farmer who missed their ideal fall seeding window. Hairy vetch is an annual or biennial spreading herb with climbing stems growing up to 3 feet long. 0000010686 00000 n Crude protein content of AU EarlyCover is about 27 percent on April 1. Ideal seeding depth: ½–1½". 0000001237 00000 n 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. Learn how your comment data is processed. Ideal temperature for germination is about 68 degrees F. If the soil temperature is too cold, the seed will not germinate. 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? 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 ���/M�@*�;%����̃���?� ����:�f��B� BĄ���nt� and consumer education. � C5c&�kF}�NF�U@��w�2h2[2+2[0W1Ob�c(gb���Y�ˍa�C��2yj���@�:�9��Q@� �������t;�5싁4[鋔���@�E�Ad� �='� of nitrogen per acre to a following spring crop. Farmers often plow it under as a green manure for nitrogen or roll it for the weed-suppressing mulch—a good application for the thick tangle of leguminous tendrils, some reaching 6 or 7 feet in length. Erosion control/Cover Crop: Hairy vetch provides good ground cover for erosion control during winter and spring. 0000001408 00000 n The corn would need not only an ample amount of nitrogen from the vetch but also plenty of dense biomass for weed suppression. The flowers are small but I think they're showy. 0000002780 00000 n 0000073862 00000 n If planting with clovers, seed rye at a slightly higher rate, about 56 lb. As temperatures gradually warm and days lengthen, seeds begin to absorb moisture, and the new seedlings grow rapidly as growing degree day units increase. In southern Illinois, hairy vetch no-tilled into fescue provided 40 to 180 lb. 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). 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. 10% - 30% vetch inclusion in a whole crop mixture with cereals and or peas.

He likes how the threeway mix guarantees biomass, builds soil and provides N. Spring seeding. Hairy vetch is one of the most winter hardy legumes. information. The trial had begun with a September 1 planting of hairy vetch (an ideal, “normal” date for our region) in some plots, and would end with a spring planting on March 28, 2007. 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 This site uses Akismet to reduce spam. %PDF-1.4 %���� Since temperature had a strong influence on germination, seeding time for some legumes should be selected to match expected temperatures for particular locations. 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. Genevieve Slocum and Dave Wilson. Thank you for your feedback. The flowers, borne in a dense one-sided spike, are violet and white to rose colored. per acre. 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. Ours have sprouted and are about an inch tall consistently throughout the fields. Hairy vetch, winter vetch, woolly vetch Uses Range Improvement: Woollypod vetch is particularly ... be treated with a fungicide at the time of planting. 0000004406 00000 n However, neither dormant seeding nor spring seeding is likely to yield enough biomass for an effective weed-suppressing mulch in a no-till system. per acre. Crimson clovers spring growth can rapidly produce a large amount of biomass. 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. View our financial 0000001856 00000 n By the time the weather's warm enough to plant tomatoes, it will be three to four feet tall and beginning to flower. 0000012342 00000 n Sow in the spring as part of a whole crop mixture, but can be autumn sown for over winter cover or grass silage mixes. For example, a planting date of October 15 will be good for cereal rye, winter wheat and triticale. 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. It is therefore vital that dormant seeding be followed by a consistently cold winter. WinterKing hairy vetch can be seeded at a rate of 10-40 lbs/acre depending on the mix or purpose. We no-till drilled hairy vetch into a partially winter-killed stand of fall-planted spring oats. View our financial The soil was on the brink of freezing beneath the residue, but it still had some give. 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. x�bb�g`b``�� �)7 A seeding rate of about 20 to 30 pounds of hairy vetch per acre is recommended. 0000009665 00000 n “With a little creativity, hairy vetch can be worked into almost any rotation.”. The scientists sowed the vetch in mid-September. 0000008715 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. 0000015012 00000 n Crimson can grow at lower temperatures better then almost any other clover species. The leaves of hairy vetch are oblong, with 5-10 pairs of leaves per leaflet. These options are best plowed down for nitrogen for the following crop, and may require additional compost or manure for fertility. 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. Pretreat the seeds in order to get them to germinate. endstream endobj 148 0 obj<>/Size 119/Type/XRef>>stream trailer Hairy vetch and common vetch are widely used as cool-season cover crops. 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. 0000004905 00000 n 0000003119 00000 n © 2021 Rodale Institute. The answer was yes and no. 0000003908 00000 n FR����]Q��aV7� 0000006092 00000 n 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. In stands where it occurs, a one year rotation with another crop will generally destroy the residue which harbors the pathogen. Buy now Tech Sheet Tech Sheet (Spanish) A dormant seed should be just as the name implies throughout the cold months—asleep and inactive beneath soil, residue and snow. For northern farmers who need a more winter-hardy vetch, look for a northern seed tag origin. vtt4�5 +�a+��bU�� Germination: 10 - 14 days. Hairy vetch (Vicia villosa) is a legume that's related to peas and beans. To fix much nitrogen, the hairy vetch should not be terminated too early in the spring (Table 1).

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). 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. Maturing earlier in the spring than hairy vetch allows this species to reach its maximum N production sooner. Hairy vetch (Vicia villosa) is a trailing winter annual, biennial, or summer annual weed that forms large mats of vegetation. 0000002253 00000 n The goal was to follow the vetch cover crop with a no-till corn crop, ideally planted into the rolled vetch mulch. Purple flowers form in early to mid summer. The plants flower 23 to 36 days earlier than commercial hairy vetch. Emergence Time: 14 days. N/A per year over 15 years for one researcher/farmer. Despite the deceptive warmth, growing hairy vetch as it was destined to grow—as a winter annual—would have been risky business.
