Seeding depths of less than one inch increase likelihood of winter kill. Using rates that are too high may increase costs, result in increased lodging, and possibly reduce yields. Count the number of seeds in the sample. 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. If seeding rate for Winter Wheat is determined by lbs/acre, the number of seeds per acre could vary by as much as 13 times! Wheat, Spring 60 1 1/2 bushels 1 1/2 bushel 2" May-April Wheat, Winter 60 90-110 lb broadcast, or drill 75-90 1 1/2 -2 bushel 2" Sept-Oct Hairy Vetch is an annual legume which provides an excellent seed for food during the fall in winter Also an insect Habitat for hatchlings to feed on. It doesn’t provide as much forage as most other plants do. 105 Ag. Seeding depth of 1 to 1 1/2 inches is optimal for quick emergence. Increase the rate up to two bushels per acre (1) if seed … 2. Winter barley can thus be planted a few days earlier than wheat, that is, from September 10 to September 20. With seeding rate determined, how can we be sure the seeder plants the desired amount? A 30 gram (1.05 ounce) TKW, which translates to 15,200 seeds per pound, is an appropriate minimum TKW for a seedlot. Wheat Use Seeding Rate Seeding Method To achieve this goal, the seeding rate for soft red winter wheat is between 1,300,000 and 1,600,000 viable seeds per acre (Table 1). Many farmers are using ATVs with spinners to seed red clover into wheat, covering a lot of ground without rutting or causing compaction. When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 53% difference in seeding rate. Seeding depth of 1 to 1 1/2 inches is optimal for quick emergence. This cool-season cereal grain is highly digestible, has 18 to 20 percent protein and holds a lot of nutritional value. When planting winter wheat, a relatively deeper seed placement is required, in which the tillering node is laid deeper. Aerially seeding wheat into standing soybeans or cotton can provide early forage. For a broadcast situation that’s going to look like 37 to 48 seeds per square foot. Winter wheat seeded late because of weather or following harvest of another crop may require a 30-60% increase in seeding rate. Table 3 provides the pounds of seed needed per acre for 6- to 14-inch row spacings and seed sizes of 12,000 to 18,000 seeds per pound, based on 18 seeds per foot of row. The lower rates are most common in drier areas. 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. Table 3 provides the pounds of seed needed per acre for 6- to 14-inch row spacings and seed sizes of 12,000 to 18,000 seeds per pound, based on 18 seeds per foot of row. To facilitate rapid emergence, seed winter wheat at a 1- to 1.5-inch soil depth. There are several options. After the mid Oct I bump my seeding rate to 70-75 lbs per acre. For irrigation, and especially with late seeding dates, row spacings of 6 to 8 inches are preferred. UNL recommends that growers base wheat seeding rates on seeds per acre not pounds per acre because of wide variances in the number of seeds per pound. A few varieties grown in Nebraska have small seed with a lower TKW, but their seed is still suitable for planting. We’ll discuss a few examples that will show you how to determine 1) Cost per pound of seed, 2) Cost of seed per acre planted, and 3) Cost of seed per pound of forage produced. He plants thicker than most farmers, aiming for 1.8 million seeds per acre, where 1.2 million seeds … Too much competition, even among small grain plants, may lead to fewer kernels per head and lower kernel weight. • Wheat is an annual cereal grain. Based on an average seed size of 13,000 kernels/lb, the following seeds/ft2 equals the following seeding rates in lbs/acre 26 Seeds/ft2 = 87 lbs/acre (our Rec for drilled wheat planted early into a good seedbed) 36 Seeds/ft2 = 120 lbs/acre 45 Seeds/ft2 = 150 lbs/acre 54 Seeds/ft2 = 180 lbs/acre With these varieties, producers should use the largest seed they can obtain. As planting gets going, here are a couple considerations when it comes to planting dates and seeding rates for Oklahoma winter wheat. 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. It was treated with Gaucho 600 and EverSol seed treatments. These devices allow the farmer to control the rate of planting. Robert Klein Western Nebraska Crops Specialist, 105 Ag. Table 1 lists optimum seeding rates for Nebraska. Remember that each variety and lot may have a different number of seeds per pound. For winter wheat, seeding rates should be increased if planting is delayed to compensate for increased winterkill potential. There are several options. Large seed tends to tiller more than small seeds; however, small dense kernels are better than large, light kernels. As we start progressing towards November wheat seeding rate needs to be increased to compensate for lost tiller production. Although this method was easy to calculate and remember from year to year, changes in production practices and equipment, and greater diversity in varieties has given way to a new and better way of seeding winter wheat: using seeds per acre. Keep in mind I have not done ANY research on seeding rate. Increase the planting rate by about 20 percent if less precise methods of planting, such as broadcast seeding, are used. Optimum winter wheat plant populations/m2 depend critically on sowing date, not variety. Table 2 identifies the pounds of seed that a grower would need based on the seed count per pound and his target seeding rate. Nitrogen guidelines, whether calculated from the equation or obtained from Table 3, should also be used for winter wheat production. 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. Weed competition can be reduced by using narrower row spacings. 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. Large, dense seeds are considered to be of better quality than low test weight seeds. No one would suggest planting a $300 bag of corn or cotton seed based on pounds per acre. Nebraska growers use seeding rates for winter wheat that vary from 30 to 180 lb per acre (320,000 to almost 3,000,000 seeds per acre). In the 2020 Nebraska Winter Wheat Variety Evaluation trial at Harlan County, winter wheat yields ranged from a low of 37.8 to a high of 93.9 bushels per acre. If determined by the number of seeds per acre, it can vary by 4.2 times. Savings or additional costs on inputs (fertilizers, crop spray etc) or higher or lower yield will influence that cost per ton figure. Seeding shallower than an inch deep puts the crowns at a higher risk for winter kill, while seeding deeper will delay emergence. How many winter wheat seeds should be planted per acre? A change in winter wheat seeding rate recommendations should be made from using pounds per acre to seeds per acre. 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. For dryland winter wheat in western Nebraska, row spacings of 10 to 14 inches are recommended. Generally, seed cleaning will add 1 to 2 lb to the seedlot's test weight by removing the small kernels. For irrigation, and especially with late seeding dates, row spacing of 6 to 8 inches is preferred. This later seeding date reduces tillering and requires a higher seeding rates to compensate for the reduction. Barley is less hardy than wheat and is not susceptible to Hessian fly. With an average seed size of 15,000 seeds per pound or 900,000 seeds per bushel, a pound of average-sized seed with 80% germination and emergence has a yield potential of approximately 1.5 bushels per acre. For dryland winter wheat in western Nebraska, row spacings of 10 to 14 inches are recommended. The United States grew 1,304,003,000 bushels (i.e. Historically, wheat growers often calculated their seeding rate based on pounds of seed per acre; however, seed size varies and it's now recommended that growers calculate their seeding rate using seeds per acre 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. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. Multiply the number of seeds counted by a factor of 22.68. On average, there are 22 seeds per head and 5 heads per plant, or 110 seeds per plant. As we hit November I am in the 80s. Increase seeding rate by 150,000 to 200,000 seeds per acre if seeding late or poor seedbed conditions. Summary. Winter wheat seeded late because of weather or following harvest of another crop may require a 30-60% increase in seeding rate. Table 1 lists optimum seeding rates for Nebraska. Optimum winter wheat plant populations/m2 depend critically on sowing date, not variety. For a broadcast situation that’s going to look like 37 to 48 seeds per square foot. If you’re using a grain drill the range is about 21 to 28 seeds per row foot. I don’t know what the wheat seed cost threshold is for switching to seeds per acre but would assume that if we ever reach this point seed quality will increase accordingly, making seeds per acre a … The higher seeding rate of two bushels per acre is generally used. With an average seed size of 15,000 seeds per pound or 900,000 seeds per bushel, a pound of average-sized seed with 80% germination and emergence has a yield potential of approximately 1.5 bushels per acre. … Depending upon varietal seed size, this equates to a range of between 74 and 119 pounds of seed per acre (Table 2). When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 153% difference in seeding rate. Oats for grain are best planted with a grain drill. It is also important to pay special attention to your seeding depth. The key is to get an optimum plant population with uniform distribution for efficient use of available resources. 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. 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). In the 2014 Nebraska Winter Wheat Variety Evaluation for 14 trials, winter wheat yields ranged from a low of 24 to a high of 127 bushels per acre. Stand estab­ lishment is highly dependent on soil moisture and rainfall after seeding, so this is not as reliable as other seeding methods. 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. The southern area of this region may use wheat as pasture. 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). 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. 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. On average, there are 22 seeds per head and 5 heads per plant, or 110 seeds per plant. Communications Bldg.Lincoln, NE 68583-0918. Some parts of this site work best with JavaScript enabled. 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. This was also the case with varieties; LG Spotlight and LG Jigsaw which produced the highest yields at the lower seed rate of 300 seeds/m2, showing yield penalties at the higher seed rate of 400 seeds/m2. The lower rates are most common in drier areas. To achieve this goal, the seeding rate for soft red winter wheat is between 1,300,000 and 1,600,000 viable seeds per acre (Table 1). Average seed costs per 50-pound bag currently range from $12.50 to $12.95. Winter wheat will remain "green" in the winter and deer will start eating it the minute it starts growing. Seeding date. Seed cleaning and sizing is essential to remove straw, chaff, dirt, stones, weed seeds, and broken, diseased or small shriveled kernels. 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. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. The higher rates are used for irrigated wheat which often is seeded in narrower rows and later in the season since it often follows another crop rather than fallow. In the seed-cleaning process, a gravity table will remove the light seed. Those who may still be planting by pounds or bushels per acre may want to consider a different approach. 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. Seed size ranged from a low of 14,000 seeds per pound to a high of 21,400 seeds per pound. The lower rates are most common in drier areas. N per acre should be applied in the fall either before or at the time of seeding. Winter Wheat Seed Size Varies. Seed winter wheat at 900,000 to 1,000,000 viable seeds per acre (about 70 lbs 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. 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. In the 2014 Nebraska Winter Wheat Variety Evaluation for 14 trials, winter wheat yields ranged from a low of 24 to a high of 127 bushels per acre. Winter wheat seeding recommendations for western Nebraska dryland winter wheat will likely be based on the number of seeds per foot of row. Increase seeding rate by 150,000 to 200,000 seeds per acre if seeding late or poor seedbed conditions. Winter Wheat Yield per Acre by State: The Top 11. 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. Winter oats intended for harvest as a grain are commonly planted at a rate of about 75 pounds per acre. Seeding rate ranges for the state are recommended between 1.6 million and 2.1 million seeds per acre. The higher rates are used for irrigated wheat which often is seeded in narrower rows and later in the season since it often follows another crop rather than fallow. The United States grew 1,304,003,000 bushels (i.e. Green earned second place in the national dryland wheat winter wheat portion of the 2018 contest. First, use the operator's manual to set the seeder. They make a good pair when planting to feed whitetails year-round. I did this because the 20 20 20 fertilizer and the nitrogen they put on the wheat seed … Ideally, winter wheat is planted while the soil and air temperatures are still warm to ensure that seedlings can emerge quickly and in plenty of time to develop a couple of tillers and a strong root system. Remember that each variety and lot may have a different number of seeds per pound. The best winter wheat crops have to have a healthy, vigorous start, good tillering (shoot growth) and be well established before winter hits. Wheat seed costs appear to be stable relative to a year ago. 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. • 11,000 to 18,000 seeds per pound • 60 pounds per bushel • HRWW can yield 50 - 90 bushels/acre Management considerations • Direct seeding winter wheat into standing crop stubble (other than corn) is recommended in order to retain snow during the winter… Then in 2000, AHDB published a project report on winter wheat seed rates.
