A representative 2 pound sample may be sent to the Federal Grain Inspection Service: USDA GIPSA FGISP.O. 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. 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. The allowable storage time for pea at select moisture contents and temperatures is shown in Table 1. Symptoms appear as caramel-brown lesions on the roots. 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. Yields will generally range from 1-2 tons/acre and protein from 15-20%, depending on the proportion of peas and oats in the mix. Most growers prefer a variety that will stand upright at harvest because that allows a faster harvest, minimal equipment modification and higher seed quality. The fungal growth can develop into hard, black bodies (sclerotia) found inside the stem, which can cause premature ripening of the plant. Average yield across rotations showed essentially the same yield for the tille… Research has shown that field pea is an excellent protein supplement in swine, beef cow and feeder calf, dairy and poultry rations. Feel free to use and share this content, but please do so under the conditions of our, NDSU Crop & Pest Report - September 24, 2020, NDSU Crop & Pest Report - September 10, 2020, NDSU Crop & Pest Report - August 27, 2020, NDSU Crop & Pest Report - August 13, 2020. 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. Field pea often is used in forage crop mixtures with small grain. 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. Average yields are 2.5 to 3.5 tons per hectare. Factory crop yields vary from a conservative 1.5 tons to a good yield of over 5 tons of shelled peas per hectare. This is typically the first question that I am asked when discussing field pea production. Hot temperatures and dry soils during the later vegetative and early reproductive stages are especially detrimental for N fixation. All insect pests but the cowpea curculio, have satisfactory control options available to growers. Reviewing harvest ease data is important because varieties within this plant type differ greatly in standability. An aeration system should be used to cool the stored pea as outdoor temperature cool, similar to other grains. Consulting the seed treatment label for its effect on rhizobium inoculants is very important. North Dakota Dry Pea Harvested Acreage, 1999 to 2015. When swathing pea, the seed needs to be at physiological maturity. The best yields were reported in … In addition, a study found that a delay in harvest affects postharvest breakage to a greater degree than seed moisture content. Consult the NDSU Extension Service publication PP1704 for more information. Normally, nodules will form on the roots two to four weeks after emergence. This system can make use of the remaining growing season because field pea is tolerant to minor frost. In the 1990s, North Dakota, South Dakota and Montana began producing dry pea. One of the most common insects in field pea is the pea aphid. Agronomics, fertility and overall nutrition can raise field pea yields as high as 94 bushels per acre After grazing, the pea stubble can be worked into the soil as a green manure or left over the winter. High-quality product is needed to receive a premium price for the crop. Cowpea curculio, Chalcodermus aeneus(Coleoptera), is a weevil (Figure 2), that seems to have originated from the Caribb… Grasshoppers are usually not a major pest problem in field pea because field pea is not typically a preferred host of grasshoppers. Field pea is well-adapted to cool, semiarid climates. For additional information on insecticides registered in field pea, please consult the NDSU Extension Service publication “North Dakota Field Crop Insect Management Guide,” E1143. Weeds such as kochia, Russian thistle, nightshade and wild buckwheat can cause harvest problems with fields that are intended to be straight combined. The optimal timing of fungicide applications varies based on conditions but often coincides with full bloom and early pod development. This research showed some differences in allowable storage time between pea and wheat. Accuracy of yield estimates depends upon an adequate number of counts being taken so as to get a representative average of the paddock. Field pea also contains 5 to 20 percent less of the trypsin inhibitors than soybean. 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. Growers can estimate dry bean yields by determining the average number of plants per acre, the average number of pods per plant and the average number of seeds per pod. A seeding rate of 3 bu/ac has been shown to yield as much as 4 bushels under normal conditions. Field pea seed will germinate at a soil temperature of 40 F. Emergence normally takes 10 to 14 days. The first criterion for selecting a variety should be market class. Infected seed will be shrunken and discolored. Field pea has moisture requirements similar to those of cereal grains. 2017-70006-27144/accession 1013592] from the USDA National Institute of Food and Agriculture. A three-year rotation will be adequate to control foliar disease pathogens. Pea seed may be stored at 14 percent moisture content as long as the seed temperature is kept below 60 degrees. Infection risk increases if field pea is planted close in rotation with broadleaf crops such as sunflower, dry edible bean, canola or mustard. Harvest management is especially important to obtain high-quality field pea to be marketed as human food or seed. Nightshade berries can stain the pea seed at harvest, causing a reduction in quality. Field pea yields can be slightly lower or similar to spring wheat on a pound or bushel basis within a specific region. Vine lifters enable producers to get under the pea vines and lift them over the cutting knife. 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. The field pea variety Durwood was planted on March 14 and March 29 in 2018 and 2019, respectively. Refer to NDSU Extension Service publication SF882, “North Dakota Fertilizer Recommendation Tables and Equation” for additional information that relates to field pea nutrient requirements. It is likely that the seed weight might be lower under drought conditions resulting in more seeds per pound. 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. Fallow used 6.0 inches of water without producing any grain (Table 4). Keeping abreast of current markets by using sources such as written or electronic agricultural publications is important. Pea aphids are small, about c inch long and light to dark green. In addition, removing foreign material may reduce the moisture content by 1 or 2 percentage points. It severely affects the appearance of the seed, lowering the grade and marketability. 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. To check for nodulation, carefully dig up a number of plants and gently clear the soil from the root mass. 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. Severe infections of ascochyta will result in premature ripening, lodging and reduced yields. Harvest should occur during humid conditions, such as at night or early morning, when pods are wet with dew, to minimize seed shatter. Symptoms of the disease include a white, frothy, fungal growth found on dead or decaying tissue. Pea normally has a single stem but can branch from nodes below the first flower. Opportunities exist to enhance the value of feed peas by using the commodity as an on farm livestock feed source. Inoculants are living organisms, so proper storage and handling is important. 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. At harvest, a small percentage of the dry field pea seeds will have dropped to the ground, even when combines are well-adjusted. In 2020, Ostlie penciled out returns on the pea/canola intercrop, … Pea seed requires considerably higher amounts of moisture for germination than cereal grains. Two-year rotation.From 1991 through 2018, in the two-year corn-soybean rotation, corn in the tilled plots averaged 6.1 bushels per acre more than corn in the no-till plots. You can also consider ordering the seeds online. A wide selection of field pea varieties exists for producers across the region. Like other crops, dry field pea yield can be estimated prior to harvest. Field pea does not ripen as uniformly as other crops, therefore harvesting while green leaves and pods remain may be necessary. Seeding date studies conducted in North Dakota indicate that field pea yields decrease significantly when seeding is delayed beyond mid-May. 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. On stems, lesions are purplish brown and are centered on nodes; when stem lesions are severe, plants often lodge and sometimes ripen prematurely. Reductions in grade may be the result of weevil damage, heat damage, bleached or shriveled seeds, and seeds with cracked seed coats. Adjust combine settings as crop and weather conditions change. After dockage has been removed, the seeds are graded. 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. Michael Wunsch, Extension Plant Pathologist; The disease overwinters on plant residue of field pea and alternate hosts. The combination of planting early and the use of resistant varieties will aid in reducing risk with this disease. 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. Field pea contains approximately 21 to 25 percent protein. Planting field pea after mid-May means it more likely will mature during warm, dry weather favorable to disease development. Indeterminate varieties are more likely to compensate for periods of hot, dry weather and are more adapted to arid regions. 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. However, aphid populations are usually kept low by heavy rains and/or by beneficial insects, such as lacewings or ladybird beetles. One type has normal leaves and vine lengths of 3 to 6 feet; the second type is the semi leafless type that has modified leaflets reduced to tendrils, resulting in shorter vine lengths of 2 to 4 feet. As can be seen in Table 1, the number of seeds per pound is determined by environment in which the crop is grown. Premium pea markets normally are limited and require a more aggressive approach by the grower. Over time the nutrients removed by the crop exceed that which the soil can supply. However, peas have lower tolerance to saline and water logged soil conditions than cereal grains. Peas will not survive long in water logged conditions. Subscribe to receive weekly PDF via e-mail, Subscribe to a feed  of individual articles. Most commercial field pea varieties are susceptible to powdery mildew but resistant varieties are available. 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. Pea vines must be dry or harvest will be extremely slow and difficult. Tolerance for seed-borne Aschochyta in Canada is very high; however, no tolerance has been established for seed-borne bacterial blight. A Crop Circle Farm triple yield by increasing the number of peppers per plant. The crop, however, is actually producing 5 tons per acre. Rates can be adjusted higher or lower depending on the conditions in the field, Effective nodules will have a pink to red coloration on their interior. The resistance to airflow of pea is not well documented, but it likely is similar to corn, so select fans for natural-air drying using corn data. A listing of potential buyers and market opportunities is available from: Northern Pulse Growers Association1710 Burnt Boat DriveBismarck, ND 58503Phone: 701-222-0128Fax: 701-222-6340. Field monitoring for Lygus bug is important during flowering and early pod development. Field peas are sensitive to a number of herbicide residues. Always read and follow label instructions. Diverse rotation. Field pea commonly is grown in rotation following small grains. A soil test should be conducted to determine the status of the primary nutrients. In 2015, approximately 275,000 acres were planted in North Dakota. In central Nebraska, nearly every acre … Field pea can be grown on a wide range of soil types, from light sandy to heavy clay. Field pea can be grown in a no till or conventional-till cropping system. The average field pea yield in Manitoba was around 55 bu. Consult the most recent “North Dakota Weed Control Guide” (NDSU Extension Service publication W253) and herbicide labels for rotational restrictions. This may require a light harrowing of the field to incorporate the seed. Opportunities also exist to utilize just-harvested pea fields for a volunteer pea cover crop. 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. Delaying harvest until oats are at the soft-dough stage of maturity and peas are undergoing pod development will increase yields but decrease quality. Feel free to use and share this content, but please do so under the conditions of our, North Dakota Dry Pea Variety Trial Results and Selection Guide. 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. Planting oat as a pre-crop also has been shown to reduce disease severity. At this moisture range, the seeds are firm and no longer penetrable with a thumbnail. 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 desiccant may be used to enhance crop drying prior to combining. 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. If the temperature of stored pea cannot be maintained below 60 degrees, then the recommended storage moisture content is 13 percent. Indeterminate varieties are later in maturity, ranging from 90 to 100 days. Figure 2. For example, semi leafless pea has a more open canopy, remain erect longer and dry down more rapidly after a rain or heavy dew than the indeterminate long vine type. Student Focused. Field pea, or “dry pea,” is marketed as a dry, shelled product for human or livestock food. The cream-colored varieties commonly grown in Minnesota and Wisconsin are used for feed or as seed for forage production. Federal grain standards have been established for whole and split field pea. Fields with a history of perennial weed problems such as Canada thistle, perennial sowthistle and field bindweed should be avoided. If an insecticide application is necessary during bloom, spray when bee foraging is minimal, preferably during the evening hours (after 8 p.m.). If an insecticide application is necessary during flowering, spray when bee foraging is minimal, preferably during the evening hours (after 8 p.m.). Table 1 lists the fertilizer recommendations for Georgia. Chalk spot damage in field pea has been as high as 27 percent when Lygus bug densities are high in fields. This site is supported in part by the Crop Protection and Pest Management Program [grant no. The green and yellow cotyledon types are the primary market classes. Determinate, semi leafless varieties that have good harvestability are more adapted to the wetter regions. 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. Like other crops, dry field pea yield can be estimated prior to harvest. Table 1 provides some seed per pound numbers for selected varieties tested in 2016. Averaging multiple observations per field will increase the accuracy of the yield estimate. The equilibrium moisture content is similar to cereal grains such as wheat and corn, so these charts can be used to estimate expected moisture contents. Relatively slow early season growth and a lack of complete ground cover by the crop canopy allow weeds to be competitive. Field pea is especially susceptible to aphid feeding injury during the flowering to early pod stage and drought stress, which can lower yields due to less seed formation and smaller seed size. Controlling diseases in field pea begins with crop rotation. 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. For example, a Canadian trial indicated that two wild mustard plants per square foot reduced pea yield as much as 35 percent. 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. Low cylinder speeds, normally 350 to 600 rpm, should be used to minimize seed cracking or splitting. Grain legumes vary widely in the proportion of the crop’s total nitrogen (N) requirement that may be met through nitrogen fixation. Read and follow all chemical labels. On pods, lesions often are sunken and can result in discolored seeds. Research Institution. Powdery mildew impacts seed yield, seed weight and seed size. Always select high-quality, disease free seed. Hans Kandel, Extension Agronomist/Broadleaf Crops; 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. However, not enough time is left of the growing season to expect to harvest a second dry pea crop for seed. The use of an inoculum labeled for soybean, clover or various other legumes will not allow the nitrogen-fixation process to occur. Land Grant. Average North Dakota Dry Pea Yield in Bushels per Acre, 1999 to 2015.Source: North Dakota Agricultural Statistics Service – USDA. 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. Applying pre-emergence herbicides before planting field pea is encouraged. 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. Under most conditions, the use of inoculants will satisfy the nitrogen requirement of a field pea crop. This permits time for moisture equalization in the seed and minimizes stresses on the seed. 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. 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. However, the number of seeds per pound differ for various varieties. Infection may occur at any stage of plant growth. 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. Both diseases survive in crop residues and are seed-borne and seed-transmitted. 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. of nitrogen per acre, depending on plant density and availability of the appropriate species of Rhizobium bacteria. Multiple hand harvests can increase pod and green pea yields of vining types (indeterminate) by about 25 percent above the indicated single harvest yields. 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. 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. Several soil applied and post emergence herbicides labeled for weed control in field pea are available. Phosphorus (P) fertilization is likely the primary concern for field pea growers. Thorough coverage of the seed is critical because seeds not exposed to the bacteria will result in plants unable to fix nitrogen. Overall, root rots are the most damaging pathogen to field pea in North Dakota. 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. Losses from shattering may be reduced by harvesting field pea before all pods are dry. Data from other tested varieties in 2016 can be found in the North Dakota Dry Pea Variety Trial Results for 2016 and Selection Guide A1469-16. Field peas, also referred to as southern peas or cowpeas, are grown on over 25 million acres throughout the world. Powdery mildew infections usually do not occur until midsummer. Generally, semi leafless pea that has good standability will avoid any serious sclerotinia infections. Julie Pasche, NDSU Plant Pathologist; 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. 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 All field pea varieties may be considered feed peas, but only selected varieties are acceptable for the green or yellow human edible market. 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. The addition of a nitrogen fertilizer may be required when field pea is planted on land with less than 30 pounds of available nitrate N in the top 2 feet of the soil profile. The total amount of nitrogen fixed by the crop also depends on favorable growing conditions. However, grasshoppers can cause damage to field pea, especially when field pea is in the flower to pod-filling stages and when populations are high. This statistic shows the yield of wheat per harvested acre in the United States from 2000 to 2019. The test weight of field pea is similar to that of wheat, so the amount of water per point of moisture that needs to be removed during drying is similar. 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. Research has indicated the importance of adequate phosphorus fertility for optimizing seed yield. Field pea has two main types. Selling peas in the premium markets is a greater challenge than marketing a traditional small-grain crop. Correct combine settings and operation are important to maintain seed quality. 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. Fields containing rocks can be rolled before emergence, up to the 5-6 node stage of the peas. Seeding pea well into moisture is critical and seeding peas into dry soil should be avoided. For more information on registered herbicides and directions for use, consult the “North Dakota Weed Control Guide” (W253). The most recent “North Dakota Dry Pea Variety Trial Results and Selection Guide” (A1469) can be useful for comparing variety data. Pea aphids have multiple generations per year and overwinter as eggs in alfalfa, clover or vetch. 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. Gregory Endres, Area Extension Specialist/Cropping Systems, Shana Forster, NDSU North Central Research Extension Center Director; Exposure to sunlight also can cause a degradation in color. Many failures with nitrogen fixation have been associated with improper application technique. Allowing the seed treatment to dry fully and adding inoculants just prior to planting always is recommended. Austrian Winter Pea Ball Clover Berseem Clover Red Clover Sub Clover White Clover Lespedeza 150 80 100 195 90 105 110 105 130 150 50-70 30-50 30-50 70-90 30-50 30-50 30-50 ... Nitrogen recommendations are based the realistic yield goal in tons per acre for the given forage and are given in tons per acre of nitrogen required. The pea seeds can be planted either by scattering throughout the field or by sowing in rows. From a single harvest, green pod yields will range from 2,500 to 4,500 pounds per acre, while shelled green and dry pea yield will range from 1,200 to 2,000 pounds per acre. 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. Indeterminate varieties tend to express more stable seed yields when moisture and heat stress impact crop development. At all temperature levels, seed coat breakage increases linearly with decreasing moisture content. 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. Any opinions, findings, conclusions, or recommendations expressed are those of the website author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. The soil-residual activity can provide weed control while field pea is emerging. Depending on the variety, you will need about 35 to 40 kg seeds per acre. Aschochyta (Mycosphaerella) blight and bacterial blight are economically important diseases of field pea that are confused easily. Producers should refer to the manufacturer’s package labels to review the proper inoculum rate and handling procedure. For feed pea, drying temperatures up to 160 degrees can be used, but seed damage likely will occur. The newer varieties that have shorter vines and are semi leafless will be easier to harvest. Box 13427Grand Forks, ND 58208 3427. Research Institution. Fertilizer Use: Nitrogen deficiency in soil is common in proso production areas, especially when planted following winter wheat. Field pea often is cracked or ground and added to cereal grain rations. Try our corporate solution for free! Aphanomyces root rot is another disease that can affect field pea. Field pea primarily is used for human consumption or as livestock feed. 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.
