This may require a light harrowing of the field to incorporate the seed. 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. Field pea has two main types. For a listing of registered seed treatments and specifics on disease control, consult the most current version of NDSU Extension Service publication PP622, “North Dakota Field Crop Fungicide Guide.”. It severely affects the appearance of the seed, lowering the grade and marketability. Field pea has moisture requirements similar to those of cereal grains. 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. However, not enough time is left of the growing season to expect to harvest a second dry pea crop for seed. Federal grain standards have been established for whole and split field pea. A desiccant may be used to enhance crop drying prior to combining. 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. The crop matures from the bottom pods upward. When seeding pea, always adjust for germination and allow for a certain percent of the seed that germinates not to become an established plant. The seed should be cooled whenever the average outdoor temperature is 10 to 15 degrees cooler than the seed temperature. Avoid placing fertilizer directly with the seed. When swathing pea, the seed needs to be at physiological maturity. 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. Aphanomyces root rot is caused by a fungal-like organism. In most cases, the breakage increases with a decrease in temperature. Maintaining a low cutter bar height is essential to reduce losses. Inoculants are available in various forms, including dry peat, liquid and granular. 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. Vine lifters enable producers to get under the pea vines and lift them over the cutting knife. Producers should refer to the manufacturer’s package labels to review the proper inoculum rate and handling procedure. Yield in 2015 was higher (maximum yield 33 bu/ac) than in 2016 (maximum yield 25-26 bu/ac) regardless of population density. Good weed control is also very important in raising high-quality human edible pea. 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. Disease is most severe with continuous wet weather. Michael Wunsch, Extension Plant Pathologist; Spores also can be carried on the seed; therefore, planting disease-free seed is very important. If an insecticide application is necessary during flowering, spray when bee foraging is minimal, preferably during the evening hours (after 8 p.m.). Field pea often is cracked or ground and added to cereal grain rations. Powdery mildew is an economic disease that is generally most severe in late-planted field pea. 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. Average North Dakota Dry … Peas will not survive long in water logged conditions. In 2015, approximately 275,000 acres were planted in North Dakota. Aschochyta blight can be managed successfully with fungicides, but fungicides are not effective against bacterial blight. Indeterminate varieties tend to express more stable seed yields when moisture and heat stress impact crop development. As can be seen in Table 1, the number of seeds per pound is determined by environment in which the crop is grown. The average field pea yield in Manitoba was around 55 bu. It overwinters in the soil as thick-walled spores (oospores) that can survive for many years. The field pea variety Durwood was planted on March 14 and March 29 in 2018 and 2019, respectively. Keeping abreast of current markets by using sources such as written or electronic agricultural publications is important. Field pea commonly is grown in rotation following small grains. 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. For more information on registered herbicides and directions for use, consult the “North Dakota Weed Control Guide” (W253). Combining should not be delayed after swathing because pea swaths are susceptible to movement by wind. 2017-70006-27144/accession 1013592] from the USDA National Institute of Food and Agriculture. Nodules will be present on the primary root and lateral roots. Cowpea curculio, Chalcodermus aeneus(Coleoptera), is a weevil (Figure 2), that seems to have originated from the Caribb… Overall, root rots are the most damaging pathogen to field pea in North Dakota. Multiple hand harvests can increase pod and green pea yields of vining types (indeterminate) by about 25 percent above the indicated single harvest yields. Splitting involves a mechanical process and results in separation of the two seed cotyledons. These bacteria, if present, live in root nodules of legumes, including peas, and convert atmospheric nitrogen into forms available to … Allowable storage time values should be considered estimates. Breakage increases at moisture contents below 14 to 16 percent. If a seed or pod will not mature, it should not be counted. Thorough coverage of the seed is critical because seeds not exposed to the bacteria will result in plants unable to fix nitrogen. The symptoms of Lygus bug feeding injury is a shriveled and deformed seed, often with chalk spot. Chalk spot damage in field pea has been as high as 27 percent when Lygus bug densities are high in fields. Research Institution. Allowing the seed treatment to dry fully and adding inoculants just prior to planting always is recommended. Markets are readily available with minimal quality restrictions for peas sold as livestock feed. Grasshopper outbreaks usually coincide with several years of low rainfall and drought periods. 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. Field pea is invariably grown as a component of a cropping system, and its interaction with other crops is an important consideration in a farmer's decision to grow it. 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. For additional information on insecticides registered in field pea, please consult the NDSU Extension Service publication “North Dakota Field Crop Insect Management Guide,” E1143. 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. Opportunities also exist to utilize just-harvested pea fields for a volunteer pea cover crop. Powdery mildew infections usually do not occur until midsummer. A seeding rate of 3 bu/ac has been shown to yield as much as 4 bushels under normal conditions. The first criterion for selecting a variety should be market class. 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. Always select high-quality, disease free seed. Fallow used 6.0 inches of water without producing any grain (Table 4). The use of an inoculum labeled for soybean, clover or various other legumes will not allow the nitrogen-fixation process to occur. The use of field pea for green fallow instead of black fallow protects the soil from erosion and improves soil 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. Figure 2. Average yield across rotations showed essentially the same yield for the tille… Field pea, or “dry pea,” is marketed as a dry, shelled product for human or livestock food. This is typically the first question that I am asked when discussing field pea production. Under these conditions, the addition of 20 to 30 pounds of nitrogen with commercial fertilizer is recommended to meet the needs of the developing field pea plant until nodulation becomes fully effective. Selling peas in the premium markets is a greater challenge than marketing a traditional small-grain crop. Field pea can be grown in a no till or conventional-till cropping system. Pea aphids have piercing-sucking mouthparts and may vector viral diseases. Avoid excessive tillage in the spring to avoid drying out the seedbed. Seeding rate is based on the number of bushels of seed per acre to be planted. This system can make use of the remaining growing season because field pea is tolerant to minor frost. 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. All field pea varieties may be considered feed peas, but only selected varieties are acceptable for the green or yellow human edible market. Producers who buy or use their own seed should know the level of seed-borne inoculum present on the seed. Field pea will fix the majority of the plants’ required nitrogen if the seed is inoculated properly. 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. The volunteer pea crop can be used for grazing or the biomass can be left on the soil or worked into the soil. Field pea is sensitive to heat stress at flowering, which can reduce pod and seed set. Both diseases survive in crop residues and are seed-borne and seed-transmitted. 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. Selecting the appropriate field pea variety should be based on the review of the many differences that exist among varieties and location grown. Producers must be certain that the inoculum product they obtain is specific for field pea. The optimal timing of fungicide applications varies based on conditions but often coincides with full bloom and early pod development. In 2020, Ostlie penciled out returns on the pea/canola intercrop, … In addition, a study found that a delay in harvest affects postharvest breakage to a greater degree than seed moisture content. Tolerance for seed-borne Aschochyta in Canada is very high; however, no tolerance has been established for seed-borne bacterial blight. Under most conditions, the use of inoculants will satisfy the nitrogen requirement of a field pea crop. Shipping Information This item’s size, weight, or shape may require an additional shipping surcharge based on the shipping location selected. Previous soil-applied herbicides may result in crop rotation restrictions when field pea is planted in the following year(s). Nitrogen fixation will take place from about four weeks after emergence through seed formation. Relatively slow early season growth and a lack of complete ground cover by the crop canopy allow weeds to be competitive. 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. Infected seed will be shrunken and discolored. At a minimum, we apply 100-150 pounds of MAP per acre. This use also can substitute water loss by evaporation or leaching from black fallow, with transpiration through plant growth, and exploits rotational benefits. R.J. French, in Encyclopedia of Food Grains (Second Edition), 2016. Consulting the seed treatment label for its effect on rhizobium inoculants is very important. In addition, removing foreign material may reduce the moisture content by 1 or 2 percentage points. Field pea has hypogeal emergence in which the cotyledons remain below the soil surface. Infection risk increases if field pea is planted close in rotation with broadleaf crops such as sunflower, dry edible bean, canola or mustard. Read and follow all chemical labels. 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. 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. Accuracy of yield estimates depends upon an adequate number of counts being taken so as to get a representative average of the paddock. Indeterminate varieties are later in maturity, ranging from 90 to 100 days. 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. 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. 24,000 lb. Field pea also contains 5 to 20 percent less of the trypsin inhibitors than soybean. Field pea typically is seeded in a narrow row spacing of 6 to 12 inches. 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. Normally, nodules will form on the roots two to four weeks after emergence. At this moisture range, the seeds are firm and no longer penetrable with a thumbnail. However, peas have lower tolerance to saline and water logged soil conditions than cereal grains. Pea aphids have multiple generations per year and overwinter as eggs in alfalfa, clover or vetch. The peas are very common and the seeds should be easily available in your area. 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. Powdery mildew impacts seed yield, seed weight and seed size. High-quality product is needed to receive a premium price for the crop. The cylinder speed should be reduced as harvest seed moisture decreases. Field pea should be combined with seed moisture of 17 to 20 percent to reduce splitting and seed coat cracking. Good storage facilities maintain the product by protecting it from direct sunlight. The Role of Field Pea in Cropping Systems. Research has indicated the importance of adequate phosphorus fertility for optimizing seed yield. Diverse rotation. When selecting within these semi leafless types, consider the impact of vine length. Agronomics, fertility and overall nutrition can raise field pea yields as high as 94 bushels per acre Floating cutter bars or flex-heads and raking-type pickup reels are available to reduce losses and increase harvest efficiency. 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. 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). Maintaining firm seed-to-soil moisture contact is critical. This allows it to be fed directly to livestock without having to go through the extrusion heating process. These trials include the most promising varieties with information recorded on the important traits necessary for making proper variety selection. Sclerotinia is rarely a disease of economic importance in dryland field pea production in North Dakota. 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. A plant density of 300,000 to 350,000 plants per acre or seven to eight plants per square foot is recommended. Yield loss typically does not occur unless the infection occurs during early to midpod set. Source: North Dakota Agricultural Statistics Service – U.S. Department of Agriculture. Seeding pea well into moisture is critical and seeding peas into dry soil should be avoided. 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. “I think about rates and percentages. You can also consider ordering the seeds online. Soil moisture is essential for germination to take place. 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. 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. However, Rhizoctonia and Pythium also can cause root rot, seedling damping-off and reduced emergence. Gregory Endres, Area Extension Specialist/Cropping Systems, Shana Forster, NDSU North Central Research Extension Center Director; Costs of tillage and idled land in black fallow are substituted with costs of field pea establishment and termination (at early flowering) in green fallow. 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. Seeding date studies conducted in North Dakota indicate that field pea yields decrease significantly when seeding is delayed beyond mid-May. Fields containing rocks can be rolled before emergence, up to the 5-6 node stage of the peas. Pea vines must be dry or harvest will be extremely slow and difficult. This is particularly true when planting into cold or wet soils or when seeding in close rotation with other broadleaf crops. 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. Crops Information The main reason for including peas is the positive effect on protein content and palatability of the resulting ensiled forage. However, aphid populations are usually kept low by heavy rains and/or by beneficial insects, such as lacewings or ladybird beetles. A Crop Circle Farm triple yield by increasing the number of peppers per plant. Cultural methods that should be used as part of an integrated weed management system include crop rotation, field selection, rapid crop establishment at an adequate density and use of clean seed. Field pea differs from fresh or succulent pea, which is marketed as a fresh or canned vegetable. Fungal spores may spread to uninfected tissue by splashing rain. 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. 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. 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. Peas can fix anywhere from 50-300 lbs. For feed pea, drying temperatures up to 160 degrees can be used, but seed damage likely will occur. A preferred crop rotation would have field pea planted with at least four cropping years between plantings. 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 … Historically, field pea primarily was grown in the Palouse region of Washington and Idaho. Land Grant. In the presence of pea roots, the oospores will germinate and eventually swimming spores (zoospores) that can infect pea roots will be formed. Hot temperatures and dry soils during the later vegetative and early reproductive stages are especially detrimental for N fixation. Fields with a history of perennial weed problems such as Canada thistle, perennial sowthistle and field bindweed should be avoided. The crop, however, is actually producing 5 tons per acre. North Dakota Dry Pea Harvested Acreage, 1999 to 2015. The green and yellow cotyledon types are the primary market classes. A well-established stand of seven to eight plants per square foot is critical for field pea to be competitive with weeds. 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. The soil-residual activity can provide weed control while field pea is emerging. This inoculant is metered through the planter and delivered directly into the seed furrow. 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. 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. The disease overwinters on plant residue of field pea and alternate hosts. Pea aphids are small, about c inch long and light to dark green. Research has shown that field pea is an excellent protein supplement in swine, beef cow and feeder calf, dairy and poultry rations. However, for this relationship to occur, the seed must be inoculated properly with the appropriate strain of Rhizobium bacteria. Many failures with nitrogen fixation have been associated with improper application technique. With a more diverse rotation, there was no yield benefit observed with tillage in this trial. It may be stored at 16 percent moisture if the seed temperature is kept below 50 degrees. Weeds such as kochia, Russian thistle, nightshade and wild buckwheat can cause harvest problems with fields that are intended to be straight combined. Table 1 provides some seed per pound numbers for selected varieties tested in 2016. The numbers in the table are intended to provide an approximate value of seeds per pound. 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. Indeterminate flowering varieties will flower for long periods, and ripening can be prolonged under cool, wet conditions. After grazing, the pea stubble can be worked into the soil as a green manure or left over the winter. 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. 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. A hard copy is available from county Extension offices. Consult the most recent “North Dakota Weed Control Guide” (NDSU Extension Service publication W253) and herbicide labels for rotational restrictions. Exposure to sunlight also can cause a degradation in color. Hans Kandel, Extension Agronomist/Broadleaf Crops; Always read and follow label instructions. This statistic shows the yield of wheat per harvested acre in the United States from 2000 to 2019. Determinate, semi leafless varieties that have good harvestability are more adapted to the wetter regions. 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 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. Field pea has high levels of the amino acids, lysine and tryptophan, which are relatively low in cereal grains. Estimating Pea Yield. Preharvest desiccants also are labeled to dry weeds for a more efficient harvest. We use gypsum to get calcium and sulfur into our fertilizer mix. For the most important root rot pathogens, little to no difference occurs between lentil and field pea in susceptibility, and a minimum of a four-year rotation would be needed for either of these crops, especially when soil conditions are relatively wet. They are sold as a dry, shelled product and used for either human consumption or livestock food. Leaf lesions often are constrained by veins and frequently become translucent or shatter as they age. Additionally, low levels of discolored and/or shrunken seed may be present. 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. 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. 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. Immature and adult Lygus bugs feed and inject a toxin into the tissues of the developing pods and seeds of peas. Field pea yields can be slightly lower or similar to spring wheat on a pound or bushel basis within a specific region. If the crop has quality problems, including bleached, split, cracked or earth-tagged seed, the livestock feed market likely will be the only option. per acre in 2019 and likely higher in 2020, Lange said. Planting oat as a pre-crop also has been shown to reduce disease severity. The combine and portable augers should be operated at full capacity and low speeds to reduce pea seed damage. Planting equipment should be calibrated or modified to allow for seed and inoculant to flow properly without cracking the seed or plugging the opener. Try our corporate solution for free! Research Institution. 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. Prices received for feed peas should be considered base prices. Growers should check their fields to determine if inoculation was successful. The cowpea curculio is the main production-limiting key pest where it occurs in the Southeastern United States. Land Grant. Most commercial field pea varieties are susceptible to powdery mildew but resistant varieties are available. Either option can improve or maintain future crop productivity. 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. One of the most common insects in field pea is the pea aphid. 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. Consult the NDSU Extension Service publication PP1704 for more information. The fungal growth can develop into hard, black bodies (sclerotia) found inside the stem, which can cause premature ripening of the plant. This is similar to the recommended temperatures for drying soybean. 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. Flowering usually begins 40 to 50 days after planting. Sclerotinia stem rot can infect field pea. 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. Seeds per Acre. Pea normally has a single stem but can branch from nodes below the first flower. 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.
