field peas yield per acre

“I think about rates and percentages. inches. Selecting the appropriate field pea variety should be based on the review of the many differences that exist among varieties and location grown. At harvest, a small percentage of the dry field pea seeds will have dropped to the ground, even when combines are well-adjusted. Lygus bug (or tarnished plant bug) has the potential of being the most serious insect pest in field pea in North Dakota. Research has shown that field pea is an excellent protein supplement in swine, beef cow and feeder calf, dairy and poultry rations. 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. Field pea seed will germinate at a soil temperature of 40 F. Emergence normally takes 10 to 14 days. The peas are very common and the seeds should be easily available in your area. Many failures with nitrogen fixation have been associated with improper application technique. Yield loss typically does not occur unless the infection occurs during early to midpod set. Grain legumes vary widely in the proportion of the crop’s total nitrogen (N) requirement that may be met through nitrogen fixation. 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. 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. After dockage has been removed, the seeds are graded. 10,040 lb. Agronomics, fertility and overall nutrition can raise field pea yields as high as 94 bushels per acre North Dakota Dry Pea Harvested Acreage, 1999 to 2015. Disease is most severe with continuous wet weather. In the presence of pea roots, the oospores will germinate and eventually swimming spores (zoospores) that can infect pea roots will be formed. Most commercial field pea varieties are susceptible to powdery mildew but resistant varieties are available. A three-year rotation will be adequate to control foliar disease pathogens. Field pea is well-adapted to cool, semiarid climates. Lygus bugs will migrate quickly into fields after alfalfa (preferred host) is cut for hay. Nodules will be present on the primary root and lateral roots. Many growers use a pickup reel to help in moving plant material off the cutter bar onto the canvas. Preharvest desiccants also are labeled to dry weeds for a more efficient harvest. Gregory Endres, Area Extension Specialist/Cropping Systems, Shana Forster, NDSU North Central Research Extension Center Director; Most growers prefer a variety that will stand upright at harvest because that allows a faster harvest, minimal equipment modification and higher seed quality. 2017-70006-27144/accession 1013592] from the USDA National Institute of Food and Agriculture. 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. Avoid excessive tillage in the spring to avoid drying out the seedbed. The numbers in the table are intended to provide an approximate value of seeds per pound. blackeyed peas, crowders, field peas, cowpeas, or just peas. Field pea also may be grown as a green manure or green fallow crop. The number of plants per acre ranges from 850,000 to 1,400,000. Infected seed will be shrunken and discolored. The Role of Field Pea in Cropping Systems. Leaf lesions often are constrained by veins and frequently become translucent or shatter as they age. Phosphorous may also be needed and is normally applied at a rate of 20 lb per acre. Estimating Pea Yield. Table 1 provides some seed per pound numbers for selected varieties tested in 2016. Relatively slow early season growth and a lack of complete ground cover by the crop canopy allow weeds to be competitive. 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. Start with counting the total plants per 1/1000th acre to determine plant population. This is particularly true when planting into cold or wet soils or when seeding in close rotation with other broadleaf crops. 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. If the economic threshold is exceeded, a single application of insecticide when 50 percent of plants have produced some young pods usually will protect the crop against yield loss. Inoculants are available in various forms, including dry peat, liquid and granular. When selecting within these semi leafless types, consider the impact of vine length. Applying pre-emergence herbicides before planting field pea is encouraged. 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. At all temperature levels, seed coat breakage increases linearly with decreasing moisture content. 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. Good weed control is also very important in raising high-quality human edible pea. 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. With a more diverse rotation, there was no yield benefit observed with tillage in this trial. Grasshoppers are usually not a major pest problem in field pea because field pea is not typically a preferred host of grasshoppers. 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. Some growers, particularly in the Swan River region, recorded yields … To reduce seed shattering, the combine reel should be adjusted to a low speed. Breakage increases at moisture contents below 14 to 16 percent. Powdery mildew is an economic disease that is generally most severe in late-planted field pea. The use of an inoculum labeled for soybean, clover or various other legumes will not allow the nitrogen-fixation process to occur. Correct combine settings and operation are important to maintain seed quality. Premium pea markets normally are limited and require a more aggressive approach by the grower. This type of variety normally will be heavily lodged at harvest and require special harvest procedures. 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. Diseased tissue is never translucent, does not readily shatter and is not constrained by veins. Nitrogen fixation will take place from about four weeks after emergence through seed formation. Weeds such as kochia, Russian thistle, nightshade and wild buckwheat can cause harvest problems with fields that are intended to be straight combined. After grazing, the pea stubble can be worked into the soil as a green manure or left over the winter. Fertilizer Use: Nitrogen deficiency in soil is common in proso production areas, especially when planted following winter wheat. The seeding rate will depend on the size of the seed. 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. In 2015, approximately 275,000 acres were planted in North Dakota. 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. 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. In most cases, the breakage increases with a decrease in temperature. 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 … Field pea should be cooled to about 30 degrees for winter storage. Hans Kandel, Extension Agronomist/Broadleaf Crops; The optimal timing of fungicide applications varies based on conditions but often coincides with full bloom and early pod development. 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 should be seeded early, in April to mid-May, so flowering will occur during potentially cooler weather in June and early July. Indeterminate varieties are later in maturity, ranging from 90 to 100 days. Adjust combine settings as crop and weather conditions change. An aeration system should be used to cool the stored pea as outdoor temperature cool, similar to other grains. The cowpea curculio is the main production-limiting key pest where it occurs in the Southeastern United States. Green Peas: Area, Production, Farm Value, Price and Yield, Ontario, 1979 - 2017 Imperial However, the number of seeds per pound differ for various varieties. Field pea often is cracked or ground and added to cereal grain rations. Try our corporate solution for free! A preferred crop rotation would have field pea planted with at least four cropping years between plantings. 24,000 lb. Research has indicated the importance of adequate phosphorus fertility for optimizing seed yield. 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 pea seeds can be planted either by scattering throughout the field or by sowing in rows. Indeterminate varieties are more likely to compensate for periods of hot, dry weather and are more adapted to arid regions. Normal application rates range from 40 - 60 lb per acre. Research at Carrington in 2008 found that fall-produced dry pea biomass reached 1,500 to 3,000 pounds per acre. 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. Always read and follow label instructions. Losses from shattering may be reduced by harvesting field pea before all pods are dry. Average yields are 2.5 to 3.5 tons per hectare. Field pea contains approximately 21 to 25 percent protein. We use gypsum to get calcium and sulfur into our fertilizer mix. Pea varieties have indeterminate or determinate flowering growth habit. 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.
