of 2,250 pounds of forage DM/acre. Seed cleaning and sizing is essential to remove straw, chaff, dirt, stones, weed seeds, and broken, diseased or small shriveled kernels. 273 113 12 5 66 Calories per pound. In addition to these agronomic reasons, calculating optimal seeding rates is important to farmers for economic reasons. If planting is delayed past the optimum time period, the initial stand should be increased by 1 percent for each day planting is delayed. This can affect weed growth, delay maturity, and create an over-reliance on tillering. Weed management also depends on tiller scouting as some labels require tillers to have two to three leaves before herbicide application. First, use the operator's manual to set the seeder. 2017 Grains and Oilseeds; Crops Acres Seeded Acres Harvested Yield (bu/acre) Production ('000 bu) Farm Value per bu. For dryland winter wheat in western Nebraska, row spacings of 10 to 14 inches are recommended. 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. Wheat has traditionally been planted by the pound. Germination should be found on the seed tag. This is for winter wheat seeded at an optimum planting date. Spring wheat is seeded at higher population compared to winter wheat. 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. A review of seedling rates vs. yield potential is helpful. Commodity Planted All Purpose Acres Harvested Acres Yield Production Price per Unit Value of Production in Dollars; POTATOES: POTATOES: 310,000: 308,000: 425 CWT / ACRE Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/(1-expected stand loss))/((seeds per pound)X(% germinaton)). Seeding rates can be reduced for products that tiller well and are planted timely in good soil conditions. Seed cleaning and sizing is essential to remove straw, chaff, dirt, … The lower rates are most common in drier areas. ©2020 Bayer Group. 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. Seeding rates are more accurate and the likelihood of achieving the targeted plant stand is improved when the rate is calculated based on the seeds per pound for the specific seed lot being planted. Seeding rate (pounds per acre) = [desired stand / (1 - expected stand loss)] / [(seeds per pound) x percent germination] Optimal stand The optimum stand of winter wheat is 900,000 to 1,000,000 plants per acre or 21 to 23 plants per square feet. The highest production of wheat on an acre of land is about 50 bushels (57 last year in Kansas). QuickRoots® is a registered trademark of Novozymes. WestBred seed suppliers running the ConnectIN Wheat Insight System can offer seed counts for each product along with Optimal Seeding Rate recommendations. Seeding rates tailored to wheat products can help farmers maximize the return on their seed investment while helping mitigate risks associated with under or over seeding. Delay in planting reduces yield potential and tiller development. Consult your agronomist, commodities broker and other service professionals before making financial, risk management, and farming decisions. Leading U.S. states for wheat yield per harvested acre 2017-2019 U.S. wheat exports by major countries of destination 2018 Total U.S. rye plantings and harvestings 2000-2019 Scouting for tillers should begin when main stems have three full leaves. For irrigation, and especially with late seeding dates, row spacings of 6 to 8 inches are preferred. This range can be as many as 10,000 to as much as 20,000 seeds per pound. Seed Cleaning and Germinability. 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. Average wheat yield for the farms in 2013 to 2016 was 66.8 bushels per acre (4.49 metric tons per hectare). Figure 1 illustrates average wheat yield per hectare for each typical farm. Yields are calculated as 60 pounds per bushel at 13.5% moisture. WestBred seed suppliers have access to new tools to determine seeding rate based on wheat seed product, seed size and density, geography, planting date, and production practices. Seeding 40 lb of seed with a weight of 15,000 seed per pound has a yield potential of 60 bushels per acre. The broadcast application of 25 lb. Please switch to a supported browser: Chrome, Edge, Firefox, Safari. For more efficient applications, use 10 to 15 lb. Estimated nutrient requirements for grain sorghum based on stage of growth are presented in Table 4. One gardener in Vermont attests to having planted 30 pounds of winter wheat on one-eighth of an acre and harvesting 250 pounds of grain in July. He said a well managed lot of … However, using seeding rates that are too low can lead to excessive tillering. If the desired stand was around one million seeds per acre, then the first lot would fall far short and the second lot would be about correct. Another factor affecting seed quality is the protein content of the seed. 350 20 5 216 103 Doien. Environmental conditions, including weather and soil fertility, affect stress on stems and vegetative growth. For example, see NebGuide G2044, Calibration of Sprayers (Also Seeders), specifically Problem 10 which illustrates how to calibrate a seeder. 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. With a 25 percent share rent — assuming a net selling price of $4.40 per bushel can be obtained — a producer would need an average yield of 51 bushels per acre to cover variable costs and rent. Winter wheat seeded late because of weather or following harvest of another crop may require a 30-60% increase in seeding rate. After seed germinability has been determined, the seeding rate can be determined. Yield Units Realistic Yields/Acre Corn (grain) bushels 100-250 Corn (silage) wet tons 12-18 Cotton bales 1-3 Peanuts lbs 3,200 Rice bushels 144 -164 Sorghum (grain) bushels 80 - 140 Sorghum (silage) wet tons 12-18 Soybeans bushels 25-55 Sweet Potatoes cwt A150-160 Watermelons cwt 100-200 Wheat (grain) bushels 40-80 All rights reserved. Purchasing certified seed can help ensure the wheat product is free of weed seed and certain diseases and offers the desired germination percentage. In general, southern locations had more stems per plant, and wheat planted in high-yielding locations had fewer stems per plant. Here is some information and average numbers from a friend of mine who grows wheat to sell to folks who make their own flour. With seeding rate determined, how can we be sure the seeder plants the desired amount? Soft White Wheat is used in flat breads, cakes, biscuits, pastries, crackers, Asian-style noodles and snack foods. 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. More information at http://www.climate.com/disclaimers. 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). 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. S per acre in the sulfate form will be adequate for growing wheat on sandy soils. “This is closer to one pound of nitrogen per bushel versus the 2 to 2.5 pounds nitrogen per bushel the university suggests is required,” he says. Actually, a high thousand kernel weight (TKW) is a better measurement of seed quality. 1 lbm/ac ≈ 0.000 112 085 115 619 446 kg/m 2.: 1 Bushel per Acre: Pounit. In the 2019 Nebraska Winter Wheat Variety Evaluation for 16 trials, winter wheat yields ranged from a low of 30 to a high of 123 bushels per acre. ($) Total Farm Value ($'000) Yield per acre. On average, there are 22 seeds per head and 5 heads per plant, or 110 seeds per plant. Compare these yields to that of small grains (wheat or cereal rye mixed with ryegrass) interseeded into warm­ season grass sod (black line) from mid­September to mid­October. A few varieties grown in Nebraska have small seed with a lower TKW, but their seed is still suitable for planting. Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/ (1-expected stand loss))/ ((seeds per pound)X (% germinaton)) A general goal is to manage fields so each plant produces three tillers. An acre of 660 by 66 international feet. To some extent, wheat is inherently capable of compensating for factors that influence yield. Tillering can be manipulated with nitrogen applications. The statistical information listed In the tables below represent a crop-by-crop average yield of 47 foods (in pounds per acre), according to two different sources. In this step, remember that a bushel of wheat is 60 pounds, but there are 8.1 pounds of moisture (a 60-pound bushel of wheat contains 13.5 percent moisture). Clearfield® is a registered trademark of BASF Corporation. 35,000 lbs per acre Worth $7,980/acre Storage Onions 65,000 lbs per acre Worth $5,206/acre Potatoes 61,000 lbs per acre Worth $4,090/acre 4,296 lbs per acre Worth $485/acre Fresh Sweet Corn 16,500 lbs per acre Worth $6,540/acre Hops 2,200 lbs per acre Worth $6,050/acre Seed size ranged from a low of 9,000 seeds per pound to a high of 14,100 seeds per pound. It becomes quickly apparent that each lot planted at 60 pounds per acre would give vastly different plant populations. Large, dense seeds are considered to be of better quality than low test weight seeds. Discuss these factors with your WestBred brand representative to get greater insight on what needs to be purchased and planted in each field. When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 153% difference in seeding rate. For winter wheat, seeding rates should be increased if planting is delayed to … This year’s 105-bushel wheat was achieved with no more than 105 pounds of actual nitrogen applied as the nitrogen source, with another 10 pounds of nitrogen in the starter fertilizer, Wert says. Communications Bldg.Lincoln, NE 68583-0918. Tall wheat products, fields with high yield potential, and over seeding can lead to plants susceptible to lodging. However, optimum seeding rate are required to optimize the plant population, which in turn is important for maximizing grain yield and quality and controlling weeds.
