These herbicides can be used as spot treatment with backpack sprayers, or can be used with high-volume equipment e. While most of the cultivated vetches are annuals, hairy vetch is grown as an annual or winter annual. Vetch can be grown following any crop harvested before mid- August. Protective covering by a companion crop or crop waste reduces the danger of winter kill. Flowers look similar to those of the sweet pea and appear in pairs on short flower stalks.

Mixing rye and crimson clover with hairy vetch seeding rates of 30, 10, and 20 lb. Doll 1 , K. Some separation of seed will occur if the two seeds are mixed together in the same seed box. Research in Maryland has shown that hairy vetch mixed with rye fixes almost the same amount of nitrogen as if it were grown without a companion. Overview Fingerprint. Widely adapted and winter hardy through Hardiness Zone 4 and into Zone 3 with snow cover , hairy vetch is a top N provider in temperate and subtropical regions. This seed burial study was initiated fall of when seeds of three hairy vetch cultivars Albert Lea, Groff, Nebraska were placed at two burial depths 3 and 15 cm with a mechanical scarification treatment scarified vs. It is necessary to perform a follow-up treatment to get any stems missed or new seedlings. The mulch retains moisture, allowing plants to use mineralized nutrients better than unmulched fields. It can be adapted to fit a 4-row planter on inch rows, and a 5- foot version for 2-row vegetable planters. The management challenge is that the mulch also lowers soil temperature, which may delay early season growth You are responsible for using pesticides according to the manufacturer's current label directions. Seed can be broadcast or drilled and should be inoculated prior to planting. Several conventional herbicides labeled in wheat applied in the fall and spring were also evaluated. No-till innovator Steve Groff of Lancaster County, PA,, uses the rolling stalk chopper to create a killed organic mulch. Vetch does not require nitrogen fertilization.

Soil under hairy vetch also had the lowest level of P remaining after growers applied high amounts of poultry litter prior to vegetable crops Researchers attribute this to dual cover crop benefits: their ability to enhance the stability of soil aggregates particles , and to decrease the likelihood that the aggregates will disintegrate in water Leaving unmowed remnant strips can lessen movement of disruptive pests while still allowing you to kill most of the cover crop Precaution and Remarks: Use on residential turf, golf courses not greens and sod farms for pre- and postemergence weed control. Figure 3. Figure 4. Control common vetch by growing a thick, healthy turf. The chevron pattern on the face of the roller came about after the designers realized that mounting the roller blades in a straight line would cause excessive bouncing, while just curving the blades in a screw pattern would act like an auger and create a pulling effect. Also, planting in a second pass in the opposite direction from which the cover crop was rolled makes getting uniform seeding depth and spacing more difficult because the planter tends to stand the plant material back up. Nitrogen source.
Hairy vetch also improves soil tilth and fixes significant amounts of nitrogen which can be utilized by subsequent crops.

Hairy vetch is often planted with cereal rye, oats or other winter grains for improved winter survival, greater winter annual weed control and increased erosion control. When used as a cover crop, hairy vetch does not normally require fertilizer unless the field has a severe P or K deficiency. Hairy vetch performs well in rotations with conventional and no-till planted row crops. In these systems, the hairy vetch is either mechanically or chemically terminated during full bloom to allow for peak nitrogen accumulation and maximum vetch kill prior to planting the row crop. When grown for hay, vetch is generally cut in the early bloom stage. For grazing, wait until the plants are at least 6 inches high. Close grazing will destroy buds needed for regrowth. Need Help?

These formulations have not been tried but may do a better job of controlling crown vetch. See Vetch Beats Plastic. He kills the vetch when it is in its pre-bloom or bloom stage, nearing its peak N-accumulation capacity. How you kill hairy vetch influences its ability to suppress weeds. One has noticeably hairy, bluish-green foliage with bluish flowers and is more cold-tolerant. For best results, the seedbed should be firm and have adequate moisture for good seed germination. In TRI trials, simultaneous rolling and no-till planting eliminated seven of the eight field passes usually necessary with conventional organic corn production, including plowing, discing, packing, planting, two rotary hoe passes and two cultivations. In southern Illinois , hairy vetch no-tilled into fescue provided 40 to lb. Vetch can be grown following any crop harvested before mid- August. Figure 6. However, attention needs to be paid to the herbicide program used; check the rotational restrictions on the label or in the Penn State Agronomy Guide. Glyphosate is a nonselective herbicide, so any other plants covered with the herbicide will be affected. Table 2. Figure Hairy vetch is often planted with cereal rye, oats or other winter grains for improved winter survival, greater winter annual weed control and increased erosion control. Even better, the mix provides a legume N boost, protects soil in fall and winter better than legumes, yet avoids the potential crop-suppressing effect of a pure rye mulch on some vegetables. Flail mowing before tillage helps, but that is a time and horsepower intensive process. Prescribed burning may be effective against seedlings or in slowing the spread of crown vetch, but it will not control large populations. Farmer Built. Its effectiveness wanes as it decomposes, falling off significantly after about three or four weeks. No-till, delayed kill. Vetches are more tolerant to acid soil conditions than most legumes.

Hairy vetch Vicia villosa is a trailing winter annual, biennial, or summer annual weed that forms large mats of vegetation. If established more than three weeks prior to latest establishment date, hairy vetch may winter-kill due to excessive fall growth. Tank mix with prodiamine 65 WG for extended preemergence grassy weed control. It is possible to establish hairy vetch after early corn silage harvest in parts of Pennsylvania. Seedlings and re-sprouts can be difficult to locate in native vegetation. Soil organic matter improvement and erosion control were additional benefits In an Ohio trial, corn no-tilled into hairy vetch at mid-bloom in May received better early season weed control from vetch mulch than corn seeded into vetch killed earlier. For optimal weed control with a hairy vetch mulch, select crops that form a quick canopy to compensate for the thinning mulch or use high-residue cultivators made to handle it. Rodeo should be used, rather than Roundup, for infestations along streams or near any other aquatic community. A disease that resembles anthracnose, but is caused by a different fungus, is prevalent on hairy vetch in the South. For sod production, apply 6 months after establishment, and do not harvest within 3 months. Check the mix carefully for weed seeds. It is important to have a lead coulter in front of each plow bottom to avoid wrapping of hairy vetch vines on the standard assembly. Investigations have started into killing hairy vetch with a hollow drum with blunt blades and then no-tilling corn into the mulch. One option is to capitalize on high quality, low-cost tomatoes that capture the late-season market premiums. The periphery of the crown vetch where there is some grass fuel may be set back, but the center of the population will not be affected.
