This use also can substitute water loss by evaporation or leaching from black fallow, with transpiration through plant growth, and exploits rotational benefits. Field pea should be seeded early, in April to mid-May, so flowering will occur during potentially cooler weather in June and early July. A representative 2 pound sample may be sent to the Federal Grain Inspection Service: USDA GIPSA FGISP.O. Phosphorus (P) fertilization is likely the primary concern for field pea growers. Historically, field pea primarily was grown in the Palouse region of Washington and Idaho. Aphanomyces root rot is caused by a fungal-like organism. A seeding depth of 2 inches is recommended, with a rule of thumb that field pea should be seeded at least ½ inch into moisture and never seeded onto the interface where soil moisture meets dry soil. Aphanomyces root rot is another disease that can affect field pea. After dockage has been removed, the seeds are graded. If the crop has quality problems, including bleached, split, cracked or earth-tagged seed, the livestock feed market likely will be the only option. Field pea commonly is grown in rotation following small grains. When seeding pea, always adjust for germination and allow for a certain percent of the seed that germinates not to become an established plant. Aschochyta (Mycosphaerella) blight and bacterial blight are economically important diseases of field pea that are confused easily. Planting the Seeds. The decision to start the harvest process will depend on three factors: Field pea can be swathed to preserve quality if crop maturity is uneven or heavy weed pressure is present. Spores also can be carried on the seed; therefore, planting disease-free seed is very important. Lygus bug (or tarnished plant bug) has the potential of being the most serious insect pest in field pea in North Dakota. Inoculants are living organisms, so proper storage and handling is important. The crop matures from the bottom pods upward. Field pea forage is approximately 18 to 20 percent protein. Land Grant. If the temperature of stored pea cannot be maintained below 60 degrees, then the recommended storage moisture content is 13 percent. This system can make use of the remaining growing season because field pea is tolerant to minor frost. Pea normally has a single stem but can branch from nodes below the first flower. Primary field pea market opportunities are for livestock feed, seed and human food. Student Focused. Field pea has shown to be well-adapted to most regions of the northern Great Plains (Figure 2). Relatively slow early season growth and a lack of complete ground cover by the crop canopy allow weeds to be competitive. The growing pea plants will provide a soil cover and protect the soil from erosive forces. Insecticide treatment for pea aphid control should be considered 1) when an economic threshold of an average of two to three aphids per 8-inch pant tips is reached or 90 to 120 aphids per 10 180-degree sweeps of a 15-inch diameter insect net are found, and 2) when few natural enemies are present. Powdery mildew is an economic disease that is generally most severe in late-planted field pea. At all temperature levels, seed coat breakage increases linearly with decreasing moisture content. To reduce seed shattering, the combine reel should be adjusted to a low speed. For additional information on fungicides labelled in field pea, consult the “North Dakota Field Crop Plant Disease Management Guide” (PP622). Thorough coverage of the seed is critical because seeds not exposed to the bacteria will result in plants unable to fix nitrogen. Finally, the number in pounds needs to be divided by the standard 60 pound per bushel to get the yield in bushel per acre adjusted to 13.5 percent moisture. An example: A field believed to be producing 4 tons per acre of dry forage per year is fertilized to achieve a 4 ton production level. Maintaining a low cutter bar height is essential to reduce losses. Field surveys performed across North Dakota from 2008 to 2015 have indicated that Fusarium and Aphanomyces root rot are most commonly observed and cause the most damage to field pea. In fact, corn in the no-till plots showed a small numeric yield advantage in the longer rotations (1.3 to 1.8 bushels per acre), but it was not statistically significant. Seeding field pea beyond mid-May will result in the crop beginning to flower in mid-July, which increases the risk of heat stress and disease problems, such as powdery mildew, reducing yields. Either option can improve or maintain future crop productivity. Drying in a high-temperature dryer should be done gradually at temperatures below 115 degrees to limit hardening or cracking of seed destined for food use and below 110 degrees to prevent germination reduction in seed. All field pea varieties may be considered feed peas, but only selected varieties are acceptable for the green or yellow human edible market. The addition of peas to oats or other small grains including barley or triticale grown for forage does not necessarily improve yield, although it can increase yields from 0-0.5 tons dry matter per acre. Diseased tissue is never translucent, does not readily shatter and is not constrained by veins. They require using aeration to cool or maintain the temperature of pea, proper monitoring and storage management similar to what is required for other types of grain. Little information exists on using natural-air or low-temperature drying to dry field pea. The North Dakota Field Pea Production guide is intended to provide growers field pea production information including variety selection principles, field selection, seeding rate, seed treatments, inoculation, fertilization, weed control, diseases, insect pests, harvest and storage and markets. Reviewing harvest ease data is important because varieties within this plant type differ greatly in standability. Field pea is a legume crop and has the inherent ability to obtain much of its nitrogen requirement from the atmosphere by forming a symbiotic relationship with Rhizobium bacteria in the soil. All insect pests but the cowpea curculio, have satisfactory control options available to growers. A conventional grain drill or air seeder that is capable of handling large seed without cracking is important. Field pea is a grain legume commonly consumed throughout the world and is popular in human vegetarian diets. The majority (more than 70 percent) of the dry pea produced in the U.S. is exported. The recommended seeding rate for peas is a target plant stand of 75 to 85 plants per square metre or seven to eight plants per square foot. Flowering usually begins 40 to 50 days after planting. The general yield formula is: plants per square foot x pods per plant x average seeds per pod x square feet per acre (43,560) = seeds per acre. Most seed treatments have little or no effect on rhizobium inoculants and nodulation; however, some seed treatments are very toxic to all formulations of inoculants. Producers should avoid planting field pea on fields that have a high level of nitrogen. Severe infections of ascochyta will result in premature ripening, lodging and reduced yields. If a seed or pod will not mature, it should not be counted. Most growers prefer a variety that will stand upright at harvest because that allows a faster harvest, minimal equipment modification and higher seed quality. Field pea is a poor competitor with weeds, especially during the first month after planting. For example, a Canadian trial indicated that two wild mustard plants per square foot reduced pea yield as much as 35 percent. The following insects are ranked from the most important and common pests in Georgia, with an emphasis on southern Georgia, where the majority of the production occurs. In central Nebraska, nearly every acre … When field pea has been grown in rotation for a few times in the same field, the need for inoculation is not as critical, compared with growing field pea for the first time in a field. Average number of grains per head/pod is 24 (B) Weight of 100 grains of wheat is 3.4g (per Table 1) (C) Yield in t/ha = (220 × 24 × 3.4) / 10,000 = 1.79. Depending on the variety, you will need about 35 to 40 kg seeds per acre. The disease overwinters on plant residue of field pea and alternate hosts. These seeds may be stimulated to germinate and start growing. We use gypsum to get calcium and sulfur into our fertilizer mix. Field pea is well-adapted to cool, semiarid climates. However, aphid populations are usually kept low by heavy rains and/or by beneficial insects, such as lacewings or ladybird beetles. Try our corporate solution for free! A good source of information to aid in variety selection is field trial evaluations conducted by the various NDSU Research Extension Centers across the state. Research has indicated the importance of adequate phosphorus fertility for optimizing seed yield. Fields containing rocks can be rolled before emergence, up to the 5-6 node stage of the peas. This may require a light harrowing of the field to incorporate the seed. Proper fertilizer source, rate and placement are necessary to avoid reductions in plant stand while at the same time meeting the P needs of the field pea plant. The most recent “North Dakota Dry Pea Variety Trial Results and Selection Guide” (A1469) can be useful for comparing variety data. This revision is based the publication Blaine Schatz, director and research agronomist at the NDSU Carrington Research Extension Center, and Greg Endres, NDSU area Extension cropping systems specialist, revised in 2009. The fungal growth can develop into hard, black bodies (sclerotia) found inside the stem, which can cause premature ripening of the plant. A soil test should be conducted to determine the status of the primary nutrients. Peas will not survive long in water logged conditions. NOTE: To convert yield per acre to yield per 100 feet of row: multiply yield per acre by the number of feet between rows and divide by 4356. Opportunities also exist to utilize just-harvested pea fields for a volunteer pea cover crop. Higher nitrogen levels also will reduce the potential of nitrogen fixation and increase the potential for lodging. R.J. French, in Encyclopedia of Food Grains (Second Edition), 2016. per acre in 2019 and likely higher in 2020, Lange said. Shipping Information This item’s size, weight, or shape may require an additional shipping surcharge based on the shipping location selected. 2017-70006-27144/accession 1013592] from the USDA National Institute of Food and Agriculture. Determinate, semi leafless varieties that have good harvestability are more adapted to the wetter regions. of nitrogen per acre, depending on plant density and availability of the appropriate species of Rhizobium bacteria. Producers should refer to the manufacturer’s package labels to review the proper inoculum rate and handling procedure. The cowpea curculio is the main production-limiting key pest where it occurs in the Southeastern United States. Symptoms appear as caramel-brown lesions on the roots. Average North Dakota Dry … Disease is most severe with continuous wet weather. Kenneth Hellevang, Extension Agricultural Engineer. Like other crops, dry field pea yield can be estimated prior to harvest. If nodulation does not occur and soil nitrogen levels are low, an application of nitrogen fertilizer over the top may be required to optimize seed yields. Field pea has improved handling characteristics at higher moisture levels. Field pea should be cooled to about 30 degrees for winter storage. Field pea will fix the majority of the plants’ required nitrogen if the seed is inoculated properly. In trials conducted at the SWROC it was observed that organic oat yield as function of seeding rate was very consistent among the varieties used, though it varied by year. Average pea yields across the province came in at 42 bushels per acre, which compares with the 10-year average of 33 bushels per acre. This indicates a plant population of 10,250 plants per acre, so the average yield per plant is approximately 3.6 pounds. The cream-colored varieties commonly grown in Minnesota and Wisconsin are used for feed or as seed for forage production. On stems, lesions are purplish brown and are centered on nodes; when stem lesions are severe, plants often lodge and sometimes ripen prematurely. Fungicides have efficacy when applied at the first signs of powdery mildew in the lower canopy but are of limited effectiveness once the disease has spread to the mid- and upper canopy. Factors to consider should include market class, yield potential, harvest ease, vine length, maturity, seed size and disease tolerance. A wide selection of field pea varieties exists for producers across the region. Pea varieties have indeterminate or determinate flowering growth habit. Fungal spores may spread to uninfected tissue by splashing rain. They are sold as a dry, shelled product and used for either human consumption or livestock food. Infected seed will be shrunken and discolored. In most cases, the breakage increases with a decrease in temperature. However, seed that is too dry will be susceptible to seed coat breakage or peeling. The combine and portable augers should be operated at full capacity and low speeds to reduce pea seed damage. Producers who buy or use their own seed should know the level of seed-borne inoculum present on the seed. Low, Good and Excellent yields are based on national data, while 5-year averages (2014-2018) are from the USDA-National Agricultural Statisitics Service New … An insecticide treatment is recommended when more than 10 Lygus bugs per 25 180-degree sweeps with a 15-inch diameter insect sweep net are present. Read and follow all chemical labels. Diverse rotation. In addition, removing foreign material may reduce the moisture content by 1 or 2 percentage points. However, the number of seeds per pound differ for various varieties. Cowpea curculio, Chalcodermus aeneus(Coleoptera), is a weevil (Figure 2), that seems to have originated from the Caribb… Planting oat as a pre-crop also has been shown to reduce disease severity. Immature and adult Lygus bugs feed and inject a toxin into the tissues of the developing pods and seeds of peas. Field pea can be grown on a wide range of soil types, from light sandy to heavy clay. Field pea has two main types. Aschochyta is always most severe at the base of the plant and is most prevalent when cool, wet weather occurs during late vegetative growth and bloom. Field pea often is cracked or ground and added to cereal grain rations. Powdery mildew infections usually do not occur until midsummer. A preferred crop rotation would have field pea planted with at least four cropping years between plantings. Adjust combine settings as crop and weather conditions change. Consult the NDSU Extension Service publication PP1704 for more information. Average yields are 2.5 to 3.5 tons per hectare. After market type is determined, growers should review the field pea performance test information from trials conducted across the state while paying particular attention to those trials reflective of their farming area. Pea vines must be dry or harvest will be extremely slow and difficult. These bacteria, if present, live in root nodules of legumes, including peas, and convert atmospheric nitrogen into forms available to … As the stimulated volunteer plants follow a main crop of field peas, high numbers of Rhizobium leguminosarum bacteria inoculum will be in the soil and nodulation is typically excellent. On pods, lesions often are sunken and can result in discolored seeds. Research at Carrington in 2008 found that fall-produced dry pea biomass reached 1,500 to 3,000 pounds per acre. Field pea can be grown in a no till or conventional-till cropping system. Field pea seeding rate was 350,000 live seeds per acre and planting was performed using a 20-foot Crustbuster no-till box drill with a 7.5-inch row spacing. Field pea is sensitive to heat stress at flowering, which can reduce pod and seed set. Seeding pea well into moisture is critical and seeding peas into dry soil should be avoided. Sclerotinia is rarely a disease of economic importance in dryland field pea production in North Dakota. Field pea yields can be slightly lower or similar to spring wheat on a pound or bushel basis within a specific region. Some growers, particularly in the Swan River region, recorded yields … The number on the bottom of the columns represents the average of all the peas in the trial, with 23 and 18 varieties tested in Minot and Hettinger, respectively. Avoid placing fertilizer directly with the seed. The average field pea yield in Manitoba was around 55 bu. Because the test weight of pea is similar to wheat, using information for wheat should provide appropriate design guidance on required airflow rates and expected drying times. Always read and follow label instructions. Producers must be certain that the inoculum product they obtain is specific for field pea. However, for this relationship to occur, the seed must be inoculated properly with the appropriate strain of Rhizobium bacteria. The total amount of biomass produced depends upon the pea plant density, the timing of initiation of regrowth, soil moisture, rainfall and the date of a killing frost. For example, pea seed-borne mosaic virus (PSbMV) is an economically damaging viral pathogen of field pea that can cause significant losses in seed yield and quality, especially when infections occur before or during flowering. Another probable cause of chalk spot is harvesting field peas at a high moisture content, which makes them susceptible to bruising if they are handled roughly. Subscribe to receive weekly PDF via e-mail, Subscribe to a feed  of individual articles. In the presence of pea roots, the oospores will germinate and eventually swimming spores (zoospores) that can infect pea roots will be formed. A hard copy is available from county Extension offices. The indeterminate nature of the long vined normal leaf type varieties may make them a preferred type in western North Dakota, where moisture stress is more prevalent. Applying pre-emergence herbicides before planting field pea is encouraged. Controlling diseases in field pea begins with crop rotation. With a typical row spacing of 51 inches and an average in-row spacing of 12 inches, each pepper plant receives 4.25 square feet of growing space. Table 1 provides some seed per pound numbers for selected varieties tested in 2016. Selling peas in the premium markets is a greater challenge than marketing a traditional small-grain crop. Seeding rate is based on the number of bushels of seed per acre to be planted. The equilibrium moisture content and allowable storage time of pea is similar to that of wheat, so the recommended storage moisture content and storage characteristics will be similar. Field pea is among the most highly efficient nitrogen-fixing crops and may obtain as much as 80 percent of its total nitrogen requirement from fixation under good growing conditions. Consult the NDSU Extension Service publication EB76, “Feeding Peas to Livestock,” for more information. Pea markets should be identified before peas are produced to optimize the ability to harvest a crop that will meet market standards. Selecting the appropriate field pea variety should be based on the review of the many differences that exist among varieties and location grown. Since the production peak in 2006 (Figure 1), field pea acres have decreased in North Dakota. Due to limited market opportunities for human food grade peas, make sure local, state or regional buyers are aware of the quality and quantity of crop you have available for sale. Another factor to consider in variety selection is the producer’s location. Overall, root rots are the most damaging pathogen to field pea in North Dakota. A three-year rotation will be adequate to control foliar disease pathogens. Start with counting the total plants per 1/1000th acre to determine plant population. Rates can be adjusted higher or lower depending on the conditions in the field, Crops Information One of the most common insects in field pea is the pea aphid. High-quality product is needed to receive a premium price for the crop. A relatively shallow root system and high water use efficiency make field pea an excellent rotational crop with small grains, especially in arid areas where soil moisture conservation is critical. A 50 bushel per acre (bu/ac) pea crop takes up 40 to 54 kg/ha (36 to 48 lb/ac) of phosphate and 35 to 43 kg/ha (31 to 38 lb/ac) is removed from the field with the seed. Exposure to sunlight also can cause a degradation in color. Premium pea markets normally are limited and require a more aggressive approach by the grower. The use of field pea for green fallow instead of black fallow protects the soil from erosion and improves soil quality. Field pea also may be grown as a green manure or green fallow crop. Research Institution. Field pea typically is seeded in a narrow row spacing of 6 to 12 inches. Federal grain standards have been established for whole and split field pea. Planting into well-drained soils and minimizing soil compaction will help manage the disease. Field pea contains approximately 21 to 25 percent protein. Averaging multiple observations per field will increase the accuracy of the yield estimate. Seed treatment fungicides show limited efficacy against the most common root rotting pathogens, Fusarium and Aphanomyces; however, the use of seed treatment fungicides is recommended for field pea to control root rots and damping-off caused by Rhizoctonia and Pythium. Previous soil-applied herbicides may result in crop rotation restrictions when field pea is planted in the following year(s). Correct combine settings and operation are important to maintain seed quality. To get the pea yield in pounds per acre, the number of seeds per acre from the formula, mentioned above, can be divided by the number of approximate seeds per pound for the variety being evaluated. Land Grant. Fallow used 6.0 inches of water without producing any grain (Table 4). Several soil applied and post emergence herbicides labeled for weed control in field pea are available. Field pea, or “dry pea,” is marketed as a dry, shelled product for human or livestock food. Always select high-quality, disease free seed. Peas can fix anywhere from 50-300 lbs. Field peas, also referred to as southern peas or cowpeas, are grown on over 25 million acres throughout the world. Avoid excessive tillage in the spring to avoid drying out the seedbed. In addition, a study found that a delay in harvest affects postharvest breakage to a greater degree than seed moisture content. The first criterion for selecting a variety should be market class. The major field pea-producing areas include Canada, Europe, Australia and the U.S. 24,000 lb. Powdery mildew develops on plant surfaces as a white fungal growth that can be wiped off easily with a finger; initially, underlying tissue remains green, but as the disease develops, underlying tissue takes on a bluish hue. Crop harvestability is a very important factor in variety selection and often is noted by harvest ease scores in trial results. Gregory Endres, Area Extension Specialist/Cropping Systems, Shana Forster, NDSU North Central Research Extension Center Director; This permits time for moisture equalization in the seed and minimizes stresses on the seed. The combination of planting early and the use of resistant varieties will aid in reducing risk with this disease. The number of plants per acre ranges from 850,000 to 1,400,000. Green Peas: Area, Production, Farm Value, Price and Yield, Ontario, 1979 - 2017 Imperial Normal application rates range from 40 - 60 lb per acre. Figure 2. Flower duration is normally two to four weeks, depending on the growth habit and environment during flowering. Julie Pasche, NDSU Plant Pathologist; For the fresh market, yields of peas in pods vary from 3 tons to 10 tons per hectare, or an average of 5 or 6 tons of pods per hectare. At this stage of growth, the majority of pods should have turned from green to yellow. Most growers will select among the semi leafless varieties that are more determinate in development. The field pea variety Durwood was planted on March 14 and March 29 in 2018 and 2019, respectively. Indeterminate varieties are more likely to compensate for periods of hot, dry weather and are more adapted to arid regions. It is likely that the seed weight might be lower under drought conditions resulting in more seeds per pound. In southern states, field pea is grown as a fall-sown cover and green manure crop. Field pea has a 330,000 (plants per acre) standard seeding rate and canola has 5 pounds (per acre) seeding rate, which is the standard rate,” he said. The newer varieties that have shorter vines and are semi leafless will be easier to harvest. Powdery mildew impacts seed yield, seed weight and seed size. It overwinters in the soil as thick-walled spores (oospores) that can survive for many years. Pea interseeded at 60 to 100 pounds per acre with a small grain such as oat can increase the protein concentration of the mixed forage by 2 to 4 percentage points and increase the relative feed value by 20 points over oat seeded alone. A six year average (2010-2015) of Agassiz field pea yield at the North Central Research Extension Center at Minot was 3,277 pounds, or 55 bushels per acre, compared with Faller hard red spring wheat at 4,241 pounds, or 71 bushels per acre. It may be stored at 16 percent moisture if the seed temperature is kept below 50 degrees. Additionally, low levels of discolored and/or shrunken seed may be present. Sclerotinia stem rot can infect field pea. Many short to medium vine and semi leafless pea cultivars have characteristics that allow straight harvesting compared with cultivars with indeterminate and prostrate vine growth. Field pea in a green fallow system yielded 3,425 pounds per acre of biomass and 103 pounds per acre of accumulated nitrogen in above-ground biomass at the Carrington Like other crops, dry field pea yield can be estimated prior to harvest. Peas contain high levels of carbohydrates, are low in fiber and contain 86 to 87 percent total digestible nutrients, which makes them an excellent livestock feed. Field pea primarily is used for human consumption or as livestock feed. An aeration system should be used to cool the stored pea as outdoor temperature cool, similar to other grains. Being a legume, peas do use a lot of calcium. The soil-residual activity can provide weed control while field pea is emerging. Consult the most recent “North Dakota Weed Control Guide” (NDSU Extension Service publication W253) and herbicide labels for rotational restrictions. Generally, postemergence herbicides should be applied to small weeds and pea (less than 2- to 4 inch height) to maximize weed control and minimize crop injury. Perennial weeds and annual weeds that emerge early in the season, including common lambsquarters, kochia, volunteer grain, wild mustard and wild oat, are very competitive with pea. As can be seen in Table 1, the number of seeds per pound is determined by environment in which the crop is grown. Multiple hand harvests can increase pod and green pea yields of vining types (indeterminate) by about 25 percent above the indicated single harvest yields. Bacterial blight, which is easily confused with Aschochyta blight, causes lesions on leaves, petioles, stems and pods that appear shiny to greasy when the lesions are fresh. North Dakota research has indicated stand loss is likely while yields are not increased. Michael Wunsch, Extension Plant Pathologist; “I think about rates and percentages. Maintaining firm seed-to-soil moisture contact is critical. Field pea often is used in forage crop mixtures with small grain. Fertilizer Use: Nitrogen deficiency in soil is common in proso production areas, especially when planted following winter wheat. Always read and follow label instructions. Box 13427Grand Forks, ND 58208 3427. To check for nodulation, carefully dig up a number of plants and gently clear the soil from the root mass. Insecticide treatment for grasshopper control should be considered when nymph (immature) or adult grasshoppers are present at 30 to 45 and 8 to 14 per square meter in the field, respectively. As a green manure crop, field pea returns approximately 25 lb/acre of nitrogen (N) to the soil. If the seed moisture content must be reduced by 5 percent or more, drying in a high-temperature dryer should take place in two passes.
