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. 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). Maturing earlier in the spring than hairy vetch allows this species to reach its maximum N production sooner. 0000004905 00000 n H���mO�0���S�K{j���y@ Z�mm���7 m����@�o�;�Mj�&D���=���/�wEpw?�����.���&0���� ���EQ� �x D(�L�(aH�PPlA��@���R ZI�*���. and consumer education.

Hairy vetch and common vetch are widely used as cool-season cover crops. In stands where it occurs, a one year rotation with another crop will generally destroy the residue which harbors the pathogen. 0000073601 00000 n For northern farmers who need a more winter-hardy vetch, look for a northern seed tag origin. Purple flowers form in early to mid summer. Duke (1981) also recounted briefly the history of hairy vetch breeding and seed production in the U.S. 0000010686 00000 n 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. 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. Drill: 15 – 20 lbs. per acre. Management Hairy vetch performs well in rotations with conventional and no-till planted row crops. 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. WinterKing hairy vetch can be seeded at a rate of 10-40 lbs/acre depending on the mix or purpose. To fix much nitrogen, the hairy vetch should not be terminated too early in the spring (Table 1). Vetch’s optimum germination temperature range is 15° to 23° C (59° to 73.4° F). No-till corn into killed vetch. 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. Hairy vetch is valuable for use in no-till systems. The scientists sowed the vetch in mid-September. 0000009665 00000 n 0000004649 00000 n Buy now Tech Sheet Tech Sheet (Spanish) 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. 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. 0000002780 00000 n 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. It has been reported to grow … Hairy vetch is a hardy type of vetch suited to wetter soil and colder winters than other winter-active legumes. Hairy vetch (Vicia villosa) is a legume that's related to peas and beans. 119 0 obj <> endobj 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. By the time the weather's warm enough to plant tomatoes, it will be three to four feet tall and beginning to flower. This site uses Akismet to reduce spam.

Crown vetch seeds germinate best in soil that is between 68 and 77 degrees Fahrenheit. 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. The more time your mix has to grow, especially during the summer, the more options you have for diverse species. endstream endobj 134 0 obj<>stream Hairy vetch develops best under cool temperature conditions on fertile loam soils; it is also productive on sandy or clay soils.

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 Crimson can grow at lower temperatures better then almost any other clover species. Hi Amber–great question! 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. However, neither dormant seeding nor spring seeding is likely to yield enough biomass for an effective weed-suppressing mulch in a no-till system. 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. 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. Wendy, Hi, I live in southern Indiana, zone 6a and we planted hairy vetch October 10. 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. Erosion control/Cover Crop: Hairy vetch provides good ground cover for erosion control during winter and spring. 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. Broadcast With Light Incorporation: 17 – 22 lbs. 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. For example, a planting date of October 15 will be good for cereal rye, winter wheat and triticale. 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. Because of its sprawling, viney growth habit, hairy vetch can suppress late winter/early spring annual weeds. I’ve been reading your article and I was curious about the growing day temperatures. Plant vetch 30 to 45 days before killing frost for winter annual management. The vetch begins to grow again in earnest early the following spring. The leaves of hairy vetch are oblong, with 5-10 pairs of leaves per leaflet. The flowers, borne in a dense one-sided spike, are violet and white to rose colored. Ideal temperature for germination is about 68 degrees F. If the soil temperature is too cold, the seed will not germinate. The branches have curly tendrils that find and cling to fences and other plants. per acre. Hairy vetch, winter vetch, woolly vetch Uses Range Improvement: Woollypod vetch is particularly ... be treated with a fungicide at the time of planting. In spring, the plant produces 3 to 10 long, weak, branching stems or vines 3 to 6 ft long. 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 next spring, the cereal rye plants provide physical support for the climbing hairy vetch … 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. View our financial 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. 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. But it is probably better than nothing for the farmer who missed their ideal fall seeding window. The leaves have 12 to 20 leaflets and terminate with tendrils. Rodale Institute is growing the organic movement through research, farmer training, These options are best plowed down for nitrogen for the following crop, and may require additional compost or manure for fertility. 0000010531 00000 n © 2021 Rodale Institute. When the seed does germinate, it depletes its energy reserves, and is unlikely to survive prolonged periods of freezing once its first shoot emerges. 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. This field is for validation purposes and should be left unchanged. Biomass comparisons of the three planting dates on June 1, 2007, revealed that fall-planted fared the best, yielding 7016 lbs/acre of dry matter, followed by the December dormant seeded vetch, at 5983 lbs/acre, and spring seeded with 4255 lbs/acre. N/A per year over 15 years for one researcher/farmer. 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. �w���bS�w�1Z��8p�H�� 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. 0000001408 00000 n x�b```a``-d`e`�fd@ A�P�cC�~ ?I���L�~N����C��RX,D1 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.
