Wheat seed costs appear to be stable relative to a year ago. Seed for planting should be above 85% germination. For this crop, 15 to 30 lb. The lower rates are most common in drier areas. Winter Wheat Seed Size Varies. Soil Selection. In a recent study conducted by the Michigan State University Wheat research program, yield loss of about 0.6 bushels per day occurs when planting after Oct. 1. … The remainder of the amount of fertilizer N needed should be topdressed early in the following spring. The key is to get an optimum plant population with uniform distribution for efficient use of available resources. Large seed may have a lower protein percentage than small, shriveled seed, but because it is larger, it may have more total protein per seed. If producers use test weight as a seed quality measurement, they should use a seed test weight above 57 lb per bushel. We harvested 10.8 tons per acre from the winter rye (as seen in picture) on May 18 th and 8.7 tons per acre on the winter wheat on May 26 th. Seed for planting should be above 85% germination. Stand estab­ lishment is highly dependent on soil moisture and rainfall after seeding, so this is not as reliable as other seeding methods. The current research is evaluating seeding rates on both 7.5- and 10-inch row spacings using seeding rates of 14, 16, 18 and 20 seeds per foot of row. When the upper layers of the soil dry out, the depth of sowing seeds … For a broadcast situation that’s going to look like 37 to 48 seeds per square foot. The increase in forage potential by using this higher seeding rate can justify the cost of the extra seed. Another factor affecting seed quality is the protein content of the seed. Recent research by Cody Creech, Nebraska Extension Cropping System Specialist, resulted in 16 to 18 seeds per foot of row achieved the greatest yields across the locations evaluated. When the upper layers of the soil dry out, the depth of sowing seeds on chernozems can be increased to 8 – 10 cm. The higher seeding rate of two bushels per acre is generally used. Another factor affecting seed quality is the protein content of the seed. With seeding rate determined, how can we be sure the seeder plants the desired amount? For irrigation, and especially with late seeding dates, row spacing of 6 to 8 inches is preferred. It also may delay maturity, increase weed competition, and fail to make use of the plant's full yield potential. Seed size ranged from a low of 14,000 seeds per pound to a high of 21,400 seeds per pound. Soft red winter wheat also has a broad optimum seeding rate range and rates between 1,000,000 and 1,500,000 seeds per acre result in highest grain and straw yields. Some parts of this site work best with JavaScript enabled. This equals seed per pound. Source: Crop Quest By Stan Schield, Division Manager, Montezuma, Kan. As producers begin to make preparations for fall seeding of winter wheat, one of the decisions to be made is how much seed to plant per acre. When considering winter annual seed costs, consider not only upfront seed costs, but also the overall costs and benefits of those seed choices. However, seed cost depends on the variety (whether public or private) and the quantity of seed being purchased. Seeding 40 lb of seed with a weight of 15,000 seed per pound has a yield potential of 60 bushels per acre. On chernozem soils and in arid regions, seeds of winter wheat are planted to a depth of 5 – 6 cm. Historically, wheat growers calculated their seeding rate based on pounds of seed per acre; however, seed size varies; so it's recommended that growers calculate their seeding rate using seeds per acre rather than pounds to provide more accurate seeding results.The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. Winter wheat is capable of compensating among yield components, which often results in similar grain yields being produced across a fairly wide range of seeding rates. Seed cleaning and sizing is essential to remove straw, chaff, dirt, stones, weed seeds, and broken, diseased or small shriveled kernels. Calculate the seeding rate using the following equation: Seeding rate (pounds per acre) = [desired stand / (1 - expected stand loss)] / [(seeds per pound) x percent germination] The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. Wheat can be broadcast at a rate of 90 to 120 lbs./acre for a pure stand or drilled at a rate of 60 to 90 lbs./acre (the photo at the top shows a plot planted with a grain drill). Large, dense seeds are considered to be of better quality than low test weight seeds. Using rates that are too high may increase costs, result in increased lodging, and possibly reduce yields. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. With seeding rate determined, how can we be sure the seeder plants the desired amount? A review of seedling rates vs. yield potential is helpful. Plants per square foot; Winter Wheat: 0.90 - 1.00: 21 - 23: Spring Wheat: 1.30 - 1.40: 30 - 32: Durum: 1.30 - 1.40: 30 - 32: Barley: 1.25 - 1.30: 28 - 30: Oat: 1.25 - 1.30: 28 -30 Seeding rates should be increased by 1% for each day planting is delayed up to a maximum rate of 1.6 million seeds per acre. Increase the rate up to two bushels per acre (1) if seed … UNL web framework and quality assurance provided by the, Apply to the University of Nebraska–Lincoln, Give to the University of Nebraska–Lincoln, Institute of Agriculture and Natural Resources, Strengthening Nebraska's Agricultural Economy, Robert Klein - Emeritus Extension Professor, Determining the Seeding Rate for Winter Wheat. Seeding rate ranges for the state are recommended between 1.6 million and 2.1 million seeds per acre. In the 2019 Harlan County tests seed size varied from 9,900 to 13,000 seed per pound. Optimum Planting Dates for Winter Wheat in Ontario . Increase seeding rate by 150,000 to 200,000 seeds per acre if seeding late or poor seedbed conditions. This statistic shows the yield of wheat per harvested acre in the United States from 2000 to 2019. However, using seeding rates that are too low can lead to excessive tillering. Seed size was smaller in 2020 than in the good conditions for seed fill in 2019. Winter wheat seeding recommendations for western Nebraska dryland winter wheat will likely be based on the number of seeds per foot of row. This later seeding date reduces tillering and requires higher seeding rates to compensate for the reduction. The graph below shows the US national average winter wheat yield in bushels per acre as reported by the USDA NASS. Generally, seed cleaning will add 1 to 2 lb to the seedlot's test weight by removing the small kernels. Winter wheat will remain "green" in the winter and deer will start eating it the minute it starts growing. Winter oats might also be planted for use as livestock feed or grazing. The number of winter wheat seeds in 1 pound can range from more than 20,000 to less than 10,000, depending on the variety and the year it was produced. Grain test weight often is used as a measure of seed quality, but test weight is a bulk density or a weight-per-volume measurement, and small seed that packs well can have a high test weight. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. In these situations the common planting rate is about 100 pounds per acre. Green earned second place in the national dryland wheat winter wheat portion of the 2018 contest. It is also important to pay special attention to your seeding depth. Average seed costs per 50-pound bag currently range from $12.50 to $12.95. To facilitate rapid emergence, seed winter wheat at a 1- to 1.5-inch soil depth. Aerially seeding wheat into standing soybeans or cotton can provide early forage. Large seed tends to tiller more than small seeds; however, small dense kernels are better than large, light kernels. After seed germinability has been determined, the seeding rate can be determined. As we hit November I am in the 80s. On average, there are 22 seeds per head and 5 heads per plant, or 110 seeds per plant. For example, see NebGuide G2044, Calibration of Sprayers (Also Seeders), specifically Problem 10 which illustrates how to calibrate a seeder. Optimum winter wheat plant populations/m2 depend critically on sowing date, not variety. generally range from 10,000 to 17,000 seeds/lb. If determined by the number of seeds per acre, it can vary by 4.2 times. It also may delay maturity, increase weed competition, and fail to make use of the plant's full yield potential. More seeds increase the number of plants, thereby increasing the leaf and stem materials used as forage or feed. A change in winter wheat seeding rate recommendations should be made from using pounds per acre to seeds per acre. For winter wheat, seeding rates should be increased if planting is delayed to compensate for increased winterkill potential. Nebraska growers use seeding rates for winter wheat that can vary from 30 to 180 lb per acre (300,000 to almost 4,000,000 seeds per acre = 13.3) if the lower rate is with a large seed and the higher rate is with a small seed. Historically, winter wheat was seeded based on pounds of seed per acre or bushels per acre. Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/(1-expected stand loss))/((seeds per pound)X(% germinaton)) When drilled at 400 seeds/m2, this dropped to 12.3 t/ha – once again confirming that high seed rates don’t necessarily bring the highest yields. UNL web framework and quality assurance provided by the, Apply to the University of Nebraska–Lincoln, Give to the University of Nebraska–Lincoln, Institute of Agriculture and Natural Resources, Strengthening Nebraska's Agricultural Economy, Determining the Seeding Rate for Your Winter Wheat. Nebraska growers use seeding rates for winter wheat that can vary from 30 to 180 lb per acre (300,000 to almost 4,000,000 seeds per acre = 13.3) if the lower rate is with a large seed and the higher rate is with a small seed. How many winter wheat seeds should be planted per acre? Higher rates at this time are discouraged as overly thick stands may encourage lodging, as was experienced by some growers during the 2010-2011 season. A 30 gram (1.05 ounce) TKW, which translates to 15,200 seeds per pound, is an appropriate minimum TKW for a seedlot. No one would suggest planting a $300 bag of corn or cotton seed based on pounds per acre. If you are planting later than the optimum date, the seeding rate should be increased by 200,000 seeds/acre per week to a maximum of 2.2 million seeds/acre to compensate for the delayed planting. Seeding rates on the lower end of the range should be reserved for fields being planted within a couple weeks of the fly-free-date. When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 153% difference in seeding rate. The remainder of the amount of fertilizer N needed should be topdressed early in the following spring. Actually, a high thousand kernel weight (TKW) is a better measurement of seed quality. Those who may still be planting by pounds or bushels per acre may want to consider a different approach. The southern area of this region may use wheat as pasture. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. The increase in forage potential by using this higher seeding rate can justify the cost of the extra seed. Weed competition can be reduced by using narrower row spacing. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. Floyd E. Bolton, crop scientist at Oregon State University, says 18 seeds per foot of row seems to be the point of diminishing yield increases, no matter the row spacing from 6 to 18 inches. • Wheat is an annual cereal grain. 2. The higher seeding rate of two bushels per acre is generally used. Robert Klein Western Nebraska Crops Specialist, 105 Ag. Seed winter wheat at 900,000 to 1,000,000 viable seeds per acre (about 70 lbs per acre). Both crops were put up as high moisture haylage and bagged with an Ag Bag silage bagger. Seed size ranged from a low of 10,700 seeds per pound to a high of 16,400 seeds per pound. Keep in mind I have not done ANY research on seeding rate. Table 2 shows the yield potential of winter wheat seeded on the recommended seeding date at 18 seeds per foot of row with 80% germination and emergence (stand establishment). For dryland winter wheat in western Nebraska, row spacings of 10 to 14 inches are recommended. September 5, 2017 ... Every 1,000 kg/ha is equal to approximately 900 lb/acre or 15 bu/acre. Planting date: The optimal window for dual-purpose wheat for most of Oklahoma is between September 10-20 (approximately day 260 in Figure 1). Since wheat seed varies in seed size (seeds/lb) and germination rates, the following equation can be used to determine seeding rate in pounds per acre. Planting date: The optimal window for dual-purpose wheat for most of Oklahoma is between September 10-20 (approximately day 260 in Figure 1). However, 45kg/ha of the same seed, costing 13.50/ha (5.40/acre) is sufficient to achieve a seed rate of 100 seeds/m 2, which allows for 40% losses to achieve the end of September target plant population. around 3.75/acre that gives a cost per acre of £525. If you’re using a grain drill the range is about 21 to 28 seeds per row foot. Table 2. Count the number of seeds in the sample. Average wheat yield for the farms in 2013 to 2017 was 65.3 bushels per acre (4.39 metric tons per hectare). Fall and Winter Grazing of Wheat. Furthermore, it can commonly produce up to 6,500 pounds of forage per acre during the hunting season. Source: Crop Quest By Stan Schield, Division Manager, Montezuma, Kan. As producers begin to make preparations for fall seeding of winter wheat, one of the decisions to be made is how much seed to plant per acre. Paul Beck and John Jennings. When planting winter wheat, a relatively deeper seed placement is required, in which the tillering node is laid deeper. Seed cleaning and sizing is essential to remove straw, chaff, dirt, stones, weed seeds, broken diseased, and small shriveled kernels. Seed winter wheat at 900,000 to 1,000,000 viable seeds per acre (about 70 lbs per acre). Nitrogen guidelines, whether calculated from the equation or obtained from Table 3, should also be used for winter wheat production. Barley is less hardy than wheat and is not susceptible to Hessian fly. The lower rates are most common in drier areas. Savings or additional costs on inputs (fertilizers, crop spray etc) or higher or lower yield will influence that cost per ton figure. With the good conditions for seed fill in 2014, there was less variation in seed size than in 2013 when the seed size in the variety test ranged from a low of 12,000 seeds per pound to a high of 23,000 seeds per pound, a 192% difference in seed size. A change in winter wheat seeding rate recommendations should be made from using pounds per acre to seeds per acre. As planting gets going, here are a couple considerations when it comes to planting dates and seeding rates for Oklahoma winter wheat. Many farmers are using ATVs with spinners to seed red clover into wheat, covering a lot of ground without rutting or causing compaction. For example, if the seed bag specifies that there are 14,000 seeds per pound and the target seeding rate is 1.8 million seeds per acre, 129 pounds of seed would be needed per acre. Floyd E.
