Seed cleaning and sizing is essential to remove straw, chaff, dirt, stones, weed seeds, and broken, diseased or small shriveled kernels. The key is to get an optimum plant population with uniform distribution for efficient use of available resources. Robert Klein Western Nebraska Crops Specialist, 105 Ag. 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. 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). Taking a germination test is essential to determine the seed viability. Seeding date. 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. The lower rates are most common in drier areas. A change in winter wheat seeding rate recommendations should be made from using pounds per acre to seeds per acre. For dryland winter wheat in western Nebraska, row spacings of 10 to 14 inches are recommended. However, using seeding rates that are too low can lead to excessive tillering. 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. N per acre should be applied in the fall either before or at the time of seeding. Seed winter wheat at 900,000 to 1,000,000 viable seeds per acre (about 70 lbs per acre). Some parts of this site work best with JavaScript enabled. Wheat also is a high-carb plant. Winter oats intended for harvest as a grain are commonly planted at a rate of about 75 pounds per acre. Furthermore, it can commonly produce up to 6,500 pounds of forage per acre during the hunting season. After seed germinability has been determined, the seeding rate can be determined. The key is to get an optimum plant population with uniform distribution for efficient use of available resources. As we saw with the 2019 winter wheat crop, if winter wheat ... 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. 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. However, using seeding rates that are too low can lead to excessive tillering. If producers use test weight as a seed quality measurement, they should use a seed test weight above 57 lb per bushel. If you’re using a grain drill the range is about 21 to 28 seeds per row foot. Large, dense seeds are considered to be of better quality than low test weight seeds. Wheat Use Seeding Rate Seeding Method For winter wheat, seeding rates should be increased if planting is delayed to compensate for increased winterkill potential. The higher rates are used for irrigated wheat, which often is seeded in narrower rows and later in the season, as it often follows another crop rather than fallow. But wheat has a bad side. Seeding 40 lb of seed with a weight of 15,000 seed per pound has a yield potential of 60 bushels per acre. 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. With these varieties, producers should use the largest seed they can obtain. 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. Too much competition, even among small grain plants, may lead to fewer kernels per head and lower kernel weight. Winter wheat seeded late because of weather or following harvest of another crop may require a 30-60% increase in seeding rate. With seeding rate determined, how can we be sure the seeder plants the desired amount? Weed competition can be reduced by using narrower row spacing. Winter Wheat Yield per Acre by State: The Top 11. Increase the rate up to two bushels per acre (1) if seed … This equals seed per pound. Also, as you can see in the pictures i put cardboard between the four wheeler and seed spreader. They make a good pair when planting to feed whitetails year-round. 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). Barley is less hardy than wheat and is not susceptible to Hessian fly. Some parts of this site work best with JavaScript enabled. In the seed-cleaning process, a gravity table will remove the light seed. ... pure live seed (PLS) per acre when using as a dualpurpose crop (grazing and grain) to ensure the proper stand density for grazing. The United States grew 1,304,003,000 bushels (i.e. Also, higher yield potential requires higher seeding rates. Seed size ranged from a low of 10,700 seeds per pound to a high of 16,400 seeds per pound. Winter Wheat Seed Size Varies. In the 2019 Harlan County tests seed size varied from 9,900 to 13,000 seed per pound. Optimum winter wheat plant populations/m2 depend critically on sowing date, not variety. As planting gets going, here are a couple considerations when it comes to planting dates and seeding rates for Oklahoma winter wheat. Higher yield potential requires higher seeding rates. Too much competition, even among small grain plants, may lead to fewer kernels per head and lower kernel weight. The lower rates are most common in drier areas. Keep in mind I have not done ANY research on seeding rate. The higher seeding rate of two bushels per acre is generally used. At the end of the last century the industry was content that seed rates for winter wheat was a done deal. For example, see NebGuide G2044, Calibration of Sprayers (Also Seeders), specifically Problem 10 which illustrates how to calibrate a seeder. The higher seeding rate of two bushels per acre is generally used. Seeding Rate. It is also important to pay special attention to your seeding depth. 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). Depending upon varietal seed size, this equates to a range of between 74 and 119 pounds of seed per acre (Table 2). Aerially seeding wheat into standing soybeans or cotton can provide early forage. 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. Oats for grain are best planted with a grain drill. Planting date: The optimal window for dual-purpose wheat for most of Oklahoma is between September 10-20 (approximately day 260 in Figure 1). N per acre should be applied in the fall either before or at the time of seeding. In winter wheat country – from Texas to Nebraska – winter wheat is generally planted the end of September through mid-October. The graph below shows the US national average winter wheat yield in bushels per acre as reported by the USDA NASS. Seeding depth of 1 to 1 1/2 inches is optimal for quick emergence. The technology trend causes an upward slope of yield over time. 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. 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. Oklahoma Winter Wheat: Planting Date and Seeding Rate Considerations. around 3.75/acre that gives a cost per acre of £525. The most consistent stands of red clover have resulted when seeding at 12 pounds to the acre. The United States grew 1,304,003,000 bushels (i.e. Seed for planting should be above 85% germination. Table 2 identifies the pounds of seed that a grower would need based on the seed count per pound and his target seeding rate. 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. Because of this, many hunters and land managers plant a blend of wheat and clover. 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. Increase the rate up to two bushels per acre (1) if seed are broadcast, (2) when seeding is delayed until Nov. 1, or (3) when seedings are made on land heavily infested with johnsongrass or wild barley, to suppress growth of these weeds. Some years, seed size can vary by 100% or more. 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. Table 2. 1.3 Billion bushels) of winter wheat in 2019. 1.3 Billion bushels) of winter wheat in 2019. 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. For this crop, 15 to 30 lb. When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 53% difference in seeding rate. 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). Communications Bldg.Lincoln, NE 68583-0918. Weed competition can be reduced by using narrower row spacings. After the mid Oct I bump my seeding rate to 70-75 lbs per acre. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. It doesn’t provide as much forage as most other plants do. 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. There are several options. Generally, seed cleaning will add 1 to 2 lb to the seedlot's test weight by removing the small kernels.
