At this stage of growth, the majority of pods should have turned from green to yellow. They are sold as a dry, shelled product and used for either human consumption or livestock food. If the crop has quality problems, including bleached, split, cracked or earth-tagged seed, the livestock feed market likely will be the only option. 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. At this moisture range, the seeds are firm and no longer penetrable with a thumbnail. 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. These fungi survive on plant debris, and spores can survive for years on field pea stubble. 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. Effective nodules will have a pink to red coloration on their interior. A certain percent of splits are allowed in whole field pea and a certain percentage of whole field pea is allowed in split field pea. Applying pre-emergence herbicides before planting field pea is encouraged. Field pea should be seeded early, in April to mid-May, so flowering will occur during potentially cooler weather in June and early July. When selecting within these semi leafless types, consider the impact of vine length. 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. Yield in 2015 was higher (maximum yield 33 bu/ac) than in 2016 (maximum yield 25-26 bu/ac) regardless of population density. Multiple hand harvests can increase pod and green pea yields of vining types (indeterminate) by about 25 percent above the indicated single harvest yields. 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. Field pea also may be grown as a green manure or green fallow crop. Peas grow well on most well-drained soil types. Planting the Seeds. 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. 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. Start with counting the total plants per 1/1000th acre to determine plant population. A hard copy is available from county Extension offices. Additionally, low levels of discolored and/or shrunken seed may be present. The fungal growth can develop into hard, black bodies (sclerotia) found inside the stem, which can cause premature ripening of the plant. Table 1 provides some seed per pound numbers for selected varieties tested in 2016. Indeterminate varieties tend to express more stable seed yields when moisture and heat stress impact crop development. Field pea also contains 5 to 20 percent less of the trypsin inhibitors than soybean. Pea normally has a single stem but can branch from nodes below the first flower. If the temperature of stored pea cannot be maintained below 60 degrees, then the recommended storage moisture content is 13 percent. Reel speed should be slow to minimize seed shatter. Varieties differ in their susceptibility to Aschochyta, but susceptibility ratings are generally unavailable and no commercial variety carries full resistance to Aschochyta or bacterial blight. Good storage facilities maintain the product by protecting it from direct sunlight. 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. Seeding date studies conducted in North Dakota indicate that field pea yields decrease significantly when seeding is delayed beyond mid-May. The disease overwinters on plant residue of field pea and alternate hosts. Field pea has high levels of the amino acids, lysine and tryptophan, which are relatively low in cereal grains. Sclerotinia is rarely a disease of economic importance in dryland field pea production in North Dakota. The main reason for including peas is the positive effect on protein content and palatability of the resulting ensiled forage. Seeding rate is based on the number of bushels of seed per acre to be planted. Michael Wunsch, Extension Plant Pathologist; The average field pea yield in Manitoba was around 55 bu. 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. All insect pests but the cowpea curculio, have satisfactory control options available to growers. 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 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. When seeding pea, always adjust for germination and allow for a certain percent of the seed that germinates not to become an established plant. Water use data indicated that field peas used 10.9 inches of water in 2015 to produce 36 bu/ac yield, which resulted in crop water productivity of 3.3 bushel per acre-inch (Table 4). This is particularly true when planting into cold or wet soils or when seeding in close rotation with other broadleaf crops. Powdery mildew infections usually do not occur until midsummer. Application of inoculant (Rhizobium leguminosarum biovar viciae) to the seed is an extremely important procedure. Field pea primarily is used for human consumption or as livestock feed. Factory crop yields vary from a conservative 1.5 tons to a good yield of over 5 tons of shelled peas per hectare. 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. Chalk spot damage in field pea has been as high as 27 percent when Lygus bug densities are high in fields. The soil-residual activity can provide weed control while field pea is emerging. Powdery mildew is an economic disease that is generally most severe in late-planted field pea. Inoculants are available in various forms, including dry peat, liquid and granular. Good weed control is also very important in raising high-quality human edible pea. 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. Since the production peak in 2006 (Figure 1), field pea acres have decreased in North Dakota. In 2015, approximately 275,000 acres were planted in North Dakota. At a minimum, we apply 100-150 pounds of MAP per acre. of nitrogen per acre, depending on plant density and availability of the appropriate species of Rhizobium bacteria. However, aphid populations are usually kept low by heavy rains and/or by beneficial insects, such as lacewings or ladybird beetles. Bacterial blight often develops at similar severity in the midcanopy as the lower canopy, and it is most sever after rain storms accompanied by strong winds or after hail storms. Research Institution. Poorly drained and saline soils should be avoided when growing field pea. Either option can improve or maintain future crop productivity. Warm seed should be cooled immediately to near average outdoor temperature after binning. Field pea can be grown on a wide range of soil types, from light sandy to heavy clay. If a seed or pod will not mature, it should not be counted. Average North Dakota Dry … Splitting involves a mechanical process and results in separation of the two seed cotyledons. Delaying harvest until oats are at the soft-dough stage of maturity and peas are undergoing pod development will increase yields but decrease quality. Flowering usually begins 40 to 50 days after planting. Combining should not be delayed after swathing because pea swaths are susceptible to movement by wind. An aeration system should be used to cool the stored pea as outdoor temperature cool, similar to other grains. Fields with a history of perennial weed problems such as Canada thistle, perennial sowthistle and field bindweed should be avoided. Photos courtesy of the Northern Pulse Growers Association. On stems, lesions are purplish brown and are centered on nodes; when stem lesions are severe, plants often lodge and sometimes ripen prematurely. Field pea commonly is grown in rotation following small grains. Infection may occur at any stage of plant growth. A soil test should be conducted to determine the status of the primary nutrients. Green weed seeds or foreign material should be cleaned from the crop before storage to reduce the potential for deterioration during storage and enhance market opportunities. 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. Tolerance for seed-borne Aschochyta in Canada is very high; however, no tolerance has been established for seed-borne bacterial blight. This allows it to be fed directly to livestock without having to go through the extrusion heating process. Consult the NDSU Extension Service publication PP1704 for more information. Field pea is well-adapted to cool, semiarid climates. 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 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. Pea aphids have multiple generations per year and overwinter as eggs in alfalfa, clover or vetch. North Dakota research has indicated stand loss is likely while yields are not increased. This is similar to the recommended temperatures for drying soybean. Like other crops, dry field pea yield can be estimated prior to harvest. Lygus bugs will migrate quickly into fields after alfalfa (preferred host) is cut for hay. 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. Nitrogen fixation will take place from about four weeks after emergence through seed formation. 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. A plant density of 300,000 to 350,000 plants per acre or seven to eight plants per square foot is recommended. In most cases, the breakage increases with a decrease in temperature. Seedlings are tolerant of spring frosts in the low 20s, and if injured by frost, a new shoot will emerge from below the soil surface until approximately seven nodes are above the soil surface. Maintaining a low cutter bar height is essential to reduce losses. This use also can substitute water loss by evaporation or leaching from black fallow, with transpiration through plant growth, and exploits rotational benefits. Land Grant. 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. Planting field pea after mid-May means it more likely will mature during warm, dry weather favorable to disease development. Shipping Information This item’s size, weight, or shape may require an additional shipping surcharge based on the shipping location selected. Most growers will select among the semi leafless varieties that are more determinate in development. Student Focused. After dockage has been removed, the seeds are graded. On leaves, petioles and pods, Aschochyta blight develops as brownish to black flecks, often with a purplish tint: on leaves, it also can cause large, tan, round to oval lesions composed of several concentric rings. If an insecticide application is necessary during bloom, spray when bee foraging is minimal, preferably during the evening hours (after 8 p.m.). Typically, long-vine varieties having normal leaf arrangement are more susceptible to sclerotinia because they tend to lodge after flowering, forming a dense canopy close to the soil surface and increasing the risk of infection. This inoculant is metered through the planter and delivered directly into the seed furrow. Crop harvestability is a very important factor in variety selection and often is noted by harvest ease scores in trial results. However, the number of seeds per pound differ for various varieties. The total amount of nitrogen fixed by the crop also depends on favorable growing conditions. To reduce seed shattering, the combine reel should be adjusted to a low speed. Box 13427Grand Forks, ND 58208 3427. The first criterion for selecting a variety should be market class. Multiple hand harvests can increase pod and green pea yields of vining types (indeterminate) by about 25 percent above the indicated single harvest yields. Refer to NDSU Extension Service publication SF882, “North Dakota Fertilizer Recommendation Tables and Equation” for additional information that relates to field pea nutrient requirements. In southern states, field pea is grown as a fall-sown cover and green manure crop. They are a member of the legume family and are capable of forming nitrogen-fixing nodules on ... 20 to 50 pounds of nitrogen per acre is needed for southernpea production. Try our corporate solution for free! 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. It is likely that the seed weight might be lower under drought conditions resulting in more seeds per pound. 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. Field pea typically is seeded in a narrow row spacing of 6 to 12 inches. Agronomics, fertility and overall nutrition can raise field pea yields as high as 94 bushels per acre Field pea, or “dry pea,” is marketed as a dry, shelled product for human or livestock food. Planting equipment should be calibrated or modified to allow for seed and inoculant to flow properly without cracking the seed or plugging the opener. However, peas have lower tolerance to saline and water logged soil conditions than cereal grains. Field pea should be combined with seed moisture of 17 to 20 percent to reduce splitting and seed coat cracking. 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 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. Initial concave settings of 0.6 inch clearance at the front and 0.3 inch at the rear, with the chaffer at 0.6 inch and sieve size at 0.4, are suggested. The cream-colored varieties commonly grown in Minnesota and Wisconsin are used for feed or as seed for forage production. The use of an inoculum labeled for soybean, clover or various other legumes will not allow the nitrogen-fixation process to occur. Several soil applied and post emergence herbicides labeled for weed control in field pea are available. Many growers use a pickup reel to help in moving plant material off the cutter bar onto the canvas. Thorough coverage of the seed is critical because seeds not exposed to the bacteria will result in plants unable to fix nitrogen. Granular inoculant has alleviated many of the concerns with inoculant applications. Indeterminate varieties are more likely to compensate for periods of hot, dry weather and are more adapted to arid regions. The numbers in the table are intended to provide an approximate value of seeds per pound. Fallow used 6.0 inches of water without producing any grain (Table 4). Being a legume, peas do use a lot of calcium. 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. 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. Avoid excessive tillage in the spring to avoid drying out the seedbed. This research showed some differences in allowable storage time between pea and wheat. Field pea yields can be slightly lower or similar to spring wheat on a pound or bushel basis within a specific region. Lesions can develop on pods, which may result in the seed becoming infected. Prices received for feed peas should be considered base prices. 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. Premium prices are associated with the human food and seed markets. The Role of Field Pea in Cropping Systems. Reviewing harvest ease data is important because varieties within this plant type differ greatly in standability. Disease is most severe with continuous wet weather. 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. As a green manure crop, field pea returns approximately 25 lb/acre of nitrogen (N) to the soil. The use of field pea for green fallow instead of black fallow protects the soil from erosion and improves soil quality. Consult the most recent “North Dakota Weed Control Guide” (NDSU Extension Service publication W253) and herbicide labels for rotational restrictions. Historically, field pea primarily was grown in the Palouse region of Washington and Idaho. Peas can fix anywhere from 50-300 lbs. Pea roots can grow to a depth of 3 to 4 feet; however, more than 75 percent of the root biomass is within 2 feet of the soil surface. Green Peas: Area, Production, Farm Value, Price and Yield, Ontario, 1979 - 2017 Imperial 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. Alternative seed-handling equipment such as belt conveyors should be considered for handling the grain intended for seed or the human food market. 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. Table 1 lists the fertilizer recommendations for Georgia. 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. Field peas' average nitrogen production is 100 lb/acre. Excess nitrogen will promote vegetative development rather than reproductive seed production. Producers should refer to the manufacturer’s package labels to review the proper inoculum rate and handling procedure. After harvest, the crop needs to be graded to determine what markets are options for the grower. Field pea should be swathed in the early morning or late afternoon when the humidity is high and the pods are tough to reduce shattering losses. 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. A three-year rotation will be adequate to control foliar disease pathogens. 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. The pathogen infects the cortex (outer portion) of the root; therefore, when plants are pulled from the soil, the cortex may slough off, leaving only a small strand of vascular tissue intact. Phosphorous may also be needed and is normally applied at a rate of 20 lb per acre. Diseased tissue is never translucent, does not readily shatter and is not constrained by veins. These trials include the most promising varieties with information recorded on the important traits necessary for making proper variety selection. 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. 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. In the presence of pea roots, the oospores will germinate and eventually swimming spores (zoospores) that can infect pea roots will be formed. 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. For feed pea, drying temperatures up to 160 degrees can be used, but seed damage likely will occur. Research at Carrington in 2008 found that fall-produced dry pea biomass reached 1,500 to 3,000 pounds per acre. Estimating Pea Yield. 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. The most recent “North Dakota Dry Pea Variety Trial Results and Selection Guide” (A1469) can be useful for comparing variety data. Ascochtya foot rot will form blackish purple lesions on the stem at the base of the plant. Immature and adult Lygus bugs feed and inject a toxin into the tissues of the developing pods and seeds of peas. Determinate, semi leafless varieties that have good harvestability are more adapted to the wetter regions. Yield loss typically does not occur unless the infection occurs during early to midpod set. 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. 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. Pea aphids have piercing-sucking mouthparts and may vector viral diseases. In addition, a study found that a delay in harvest affects postharvest breakage to a greater degree than seed moisture content. 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. Federal grain standards have been established for whole and split field pea. The green and yellow cotyledon types are the primary market classes. Fungal spores may spread to uninfected tissue by splashing rain. Phosphorus (P) fertilization is likely the primary concern for field pea growers. 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. In 2020, Ostlie penciled out returns on the pea/canola intercrop, … Field pea is an annual cool season grain legume or pulse crop. The majority (more than 70 percent) of the dry pea produced in the U.S. is exported. Always read and follow label instructions. Averaging multiple observations per field will increase the accuracy of the yield estimate. On pods, lesions often are sunken and can result in discolored seeds. Source: North Dakota Agricultural Statistics Service – U.S. Department of Agriculture. Field pea will fix the majority of the plants’ required nitrogen if the seed is inoculated properly. Most growers prefer a variety that will stand upright at harvest because that allows a faster harvest, minimal equipment modification and higher seed quality. Julie Pasche, NDSU Plant Pathologist; 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. Using recommended seeding rates and establishing an optimal plant stand is important for maximizing yields. Aschochyta blight can be managed successfully with fungicides, but fungicides are not effective against bacterial blight. This system can make use of the remaining growing season because field pea is tolerant to minor frost. Figure 2. Symptoms appear as caramel-brown lesions on the roots. 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. Flower duration is normally two to four weeks, depending on the growth habit and environment during flowering. Factors to consider should include market class, yield potential, harvest ease, vine length, maturity, seed size and disease tolerance.
