“It gives a good, thick stand,” he says. One cover cropping practice used by winter wheat growers involves frost seeding medium red clover seed into the wheat during freeze-thaw periods, usually in March or early April. In low-fertility or light-textured soils, consider a mixed seeding with a legume (80). Winter annual use. See Wheat Boosts Income and Soil Protection. An irrigation option ensures adequate soil moisture—for the wheat stand in fall or the potato crop in spring, she adds. NC State Extension is the largest outreach program at NC State University. Nitrogen uptake is only half of that of rye in the fall Other Options Choosing wheat as a small-grain cover crop offers the flexibility in late spring or early summer to harvest a grain crop. Poor Soil / Hungry Crops . Based in the College of Agriculture and Life Sciences, we reach millions of North Carolina citizens each year through local centers in the state's 100 counties and with the Eastern Band of Cherokee Indians. If frostseeding, use the full seeding rates for both species, according to recent work in Iowa (34). Also, the peas are field peas and don’t require tall trellising. In regions where these crops survive winter, they will grow vigorously in early spring. Mixed seeding or nurse crop. It adds up, however. In Colorado, wheat planted in August after early vegetables produced more than 4,000 lb. Erosion control. The effect of these cover crops on the next winter wheat crop was compared to summer fallow fields (i.e., weeds controlled by regularly disking the soil at 4 inches every 15 days). “Volunteer rye, however, is a serious problem in wheat grown in the West, and wheat is a common rotation crop for potato growers in the Pacific Northwest.”. To plant winter wheat as cover crop, rake the garden smooth, removing debris and large rocks. After drilling wheat, Carter goes back and mows the cotton stalks to leave some field residue until the wheat establishes. About 80 percent of the K is recycled if the stems and leaves aren’t removed from the field at harvest. A Maryland study of 25 wheat cultivars showed no major differences in overall biomass production at maturity (92). You also could overseed winter wheat prior to cotton defoliation and harvesting. Also in Maryland, wheat produced up to 12,500 lb. Winter wheat works well in mixtures with other small grains or with legumes such as hairy vetch. Winter Cover Crop Three Sisters Plan. USDA is an equal opportunity provider and employer. ... Winter rye; Winter wheat; Winter cover crops can help you improve and make use of your garden year round. Mid-quality soil nutrient content is best for winter wheat with an appropriate supply of nitrogen being critical for the wheat to be able to establish itself in time before winter dormancy. Cereal Rye. In the Corn Belt and northern U.S., undersow red clover or frostseed sweetclover into a wheat nurse crop if you want the option of a year of hay before going back to corn. “We usually kill the wheat from early to mid May— a week or two after planting potatoes. The Austrian winter pea pods have 3-5 round dark seeds that are commonly mottled with purple or brown spots. Some examples of crops that will survive the winter — depending on winter temperature lows — include winter rye, winter wheat, hairy vetch, Austrian winter peas, and crimson clover. But even better, as the cover crop breaks down in the soil next spring, it gives back all of it nutrients. If cover crop planting is delayed, consider sowing rye instead. Winter rye (Secale cereale) and annual ryegrass (Lolium multiflorum) are two completely different plants. Amount of spring rainfall and soil moisture and the wheat growth rate determine the optimal dates for killing wheat and planting potatoes. P2O5 and 60 lb. Rye tends to be more winter hardy than winter wheat, so some of the issues related to snow cover are less critical for its survival than winter wheat. As a fall-sown cereal, wheat competes well with most weeds once it is established (71). The discussion around adding winter wheat and a cover crop into a rotation to build soils and improve the bottom line is supported by concrete evidence, but some growers continue to resist the recommendation. Winter wheat cover crops are designed to lessen erosion from runoff of water and wind and to retain the soil. Hard winter wheat, Austrian winter peas, and tillage radish make good sisters. SARE Outreach operates under cooperative agreements with the University of Maryland to develop and disseminate information about sustainable agriculture. It is increasingly grown instead of rye because it is cheaper and easier to manage in spring. The practice has proven viable for many of our growers, despite the disadvantage of not having good seed-to-soil contact. Adequate but not excessive N is important during wheat’s early growth stages (prior to stem growth) to ensure adequate tillering and root growth prior to winter dormancy. With rye, he has to disk two to three weeks earlier in spring to incorporate the biomass, which can be a problem in wet conditions. Seed at a low to medium rate when soil moisture is plentiful (71). Sow winter rye in late summer or early autumn after your vegetables have been harvested, and then watch out! Winter wheat can be grown as a cash crop or a cover crop, although you should manage each differently. Some of these species are cereal rye, wheat, triticale, barley, and hairy vetch. Type: winter annual cereal grain; can be spring-planted Roles: prevent erosion, suppress weeds, scavenge excess nutrients, add organic matter Mix with: annual legumes, ryegrass or other small grains See charts, pp. See Wheat Boosts Income and Soil Protection. Several long-term (14 & 15 years) crop rotations studies (Monmouth and Perry, Illinois and Ridgetown, Ontario) have shown including winter wheat in the rotation with corn and soybeans increases water stable aggregates, which is a very sensitive and good indicator for soil physical health. Winter wheat can be grown as a cash crop or a cover crop, although you should manage each differently. With or without underseeding a legume or legume-grass mix, winter wheat provides great grazing and nutritional value and can extend the grazing season. It provides a cash-grain option while also opening a spot for a winter annual legume in a corn>soybean or similar rotation. Winter wheat is less likely to become a weed and is easier to get rid of than barley or rye. The 100 days between winter wheat harvest and winter wheat planting are a fine time to grow short-season cover crop blends, according to Windom, Kansas, farmer Joe Swanson. In parts of Zone 6 and warmer, you also have a dependable double-crop option. Pairing a winter wheat cover crop with a reduced herbicide program in the inland Pacific Northwest could provide excellent weed control in potatoes grown on light soils in irrigated, semiarid regions. At the 2018 Wheat Field Day at the Princeton Research and Education Center, Dr. Erin Haramoto presented Using Wheat as a Cover Crop. Cheaper and easier to manage than rye, winter wheat’s popularity as a cover crop is exponentially growing. They also contribute to the reduction of mineral leaching and compaction , suppress the amount of weed growth, reduce insect pests and diseases, and increase crop yield. Some starter N (50 to 60 lb./A) can help the wheat establish. They add organic material that then gets tilled under in spring prior to planting your summer crops.. Using wheat as a winter cover crop isn’t new to agriculture, though it is new in some parts of the Southeastern U.S. It is usually planted in the Great Plains region as a cash grain but is also an excellent green manure cover crop. Winter wheat grasses are also easier to grow as they germinate and establish much more quickly than cover crops, such as clover. This field study was conducted from 2008–2011 at Garden City, KS. Managed as a cover crop, wheat rarely poses an insect or disease risk. The effect of these cover crops on the next winter wheat crop was compared to summer fallow fields (i.e., weeds controlled by regularly disking the soil at 4 inches every 15 days). You might not need a burndown herbicide, either. 66 to 72, for ranking and management summary. K2O per acre by boot stage. With irrigation or in humid regions, you could harvest 45- to 60-bushel wheat, then double crop with soybeans, cotton or another summer crop. She recommends drilling winter wheat at 90 lb./A into a good seedbed, generally in mid- September in Idaho. Two tests were established in disked and cultipacked fields near Chickasha and Perkins in mid-June 2016 and 201 No f7. If wheat diseases or pests are a major concern in your area, rye or barley might be a better choice as an overwintering cover crop that provides a grain option, despite their lower grain yield. Biomass production and N uptake are fairly slow in autumn. The grass is not an ornamental species and is best suited for large beds and open grassland. Having winter-hardy species in the mixture will help to maintain cover crop benefits throughout the winter and into the spring. A 50 bushel wheat crop can take up 20 to 25 lb. There are many herbicides registered for use in wheat but good weed control for a cover crop should not be expensive and may not be needed. “In our area, growers can deep rip in fall, disk and build the beds (hills), then drill wheat directly into the beds,” she says.
