October-sown wheat will generally produce two to three good tillers per plant and will reach the 60 heads per square foot target when sown at 60 pounds per acre. Delay in planting reduces yield potential and tiller development. At a 60 pounds per acre seeding rate, this will deliver 18 seeds to 22 seeds per square foot. 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. Robert Klein Western Nebraska Crops Specialist, 105 Ag. Using rates that are too high may increase costs, result in increased lodging, and possibly reduce yields. Seed cleaning and sizing is essential to remove straw, chaff, dirt, … He said a well managed lot of … In top wheat producing states Kansas, North Dakota, and Montana, non irrigated wheat yields are typically 30-50 bushels per acre with there being 60 lbs in a bushel. 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. 267 171 Dozen. Soft white winter wheat has a broad optimum seeding rate range and rates of about 120 pounds or 2 bushels per acre usually result in the highest grain and straw yields. 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. With these varieties, producers should use the largest seed they can obtain. A review of seedling rates vs. yield potential is helpful. FieldView™ is a trademark of The Climate Corporation. 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. WestBred seed suppliers running the ConnectIN Wheat Insight System can offer seed counts for each product along with Optimal Seeding Rate recommendations. 350 20 5 216 103 Doien. 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). However, using seeding rates that are too low can lead to excessive tillering. Weed management also depends on tiller scouting as some labels require tillers to have two to three leaves before herbicide application. How many winter wheat seeds should be planted per acre? As mentioned earlier, new crop wheat bids in eastern Arkansas currently range from $4.22 to $4.45. “Then, we come back with that much again about midspring, for a total of 100 to 120 pounds.” Too much N, especially in one shot, and the wheat is more prone to lodging and disease, he says. Large, dense seeds are considered to be of better quality than low test weight seeds. Precise conversions are used for exact technical analysis. ($) Total Farm Value ($'000) 73.8 1,960 a 5, 940 6,000 1,200 1,200 1,154 1,086 960 524 »784 840 60 ceoo 2,190 219 98.55 Dressed (pounds). 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. 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. It may be beneficial to increase seeding rates for products that tiller less, are planted later than the optimum, or are planted in rough seedbed conditions. Seed for planting should be above 85% germination. It also may delay maturity, increase weed competition, and fail to make use of the plant's full yield potential. First, use the operator's manual to set the seeder. The heights of wheat products can vary from short and medium-short to tall. Purchasing certified seed can help ensure the wheat product is free of weed seed and certain diseases and offers the desired germination percentage. For dryland winter wheat in western Nebraska, row spacings of 10 to 14 inches are recommended. “We recommend 30 to 50 pounds per acre of N with conventional tillage and 40 to 60 pounds with no-till,” says Lee. Also, higher yield potential requires higher seeding rates. These do not guarantee results. Larger, denser seeds means fewer seeds planted. Table 1 lists optimum seeding rates for Nebraska. In general, an initial stand of 30 to 32 plants/ft2, which is about 1.3 to 1.4 million plants/acre, maximizes yield potential. For a grain yield of 7,500 pounds per acre, sorghum needs approximately 25 inches of water during the growing season. 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 key is to get an optimum plant population with uniform distribution for efficient use of available resources. 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. 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. Figure 1 illustrates average wheat yield per hectare for each typical farm. Environmental conditions, including weather and soil fertility, affect stress on stems and vegetative growth. Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/(1-expected stand loss))/((seeds per pound)X(% germinaton)). 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 Quantifying tillers is important for management practices. 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. Pounds 35 no 100 20 20 40 16 34 35 14 1 0 24 Live (poimds). 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. The number of heads per pure live seed planted decreases, with increased seeding rates. 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. Clearfield® is a registered trademark of BASF Corporation. 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. For winter wheat, seeding rates should be increased if planting is delayed to … Weed competition can be reduced by using narrower row spacings. The highest production of wheat on an acre of land is about 50 bushels (57 last year in Kansas). 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. 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. Too much competition, even among small grain plants, may lead to fewer kernels per head and lower kernel weight. 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. Then, use one of the several items available to help calibrate the seeder. 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. Actually, a high thousand kernel weight (TKW) is a better measurement of seed quality. Although yield is only a partial gauge of performance, it reflects the available production technology across farms. Unit Descriptions; 1 Pound per Acre: Mass of pounds per area of an acre. The number of winter wheat seeds in one pound varies depending on the variety and the condition under which it was produced. 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. S per acre in the sulfate form will be adequate for growing wheat on sandy soils. Average wheat yield for the farms in 2013 to 2016 was 66.8 bushels per acre (4.49 metric tons per hectare). An international pound of 0.45359237 kilograms. Seeding rates are typically expressed as seeds per acre or pounds per acre. 273 113 12 5 66 Calories per pound. In general, southern locations had more stems per plant, and wheat planted in high-yielding locations had fewer stems per plant. All rights reserved. Seed Cleaning and Germinability. Yields are calculated as 60 pounds per bushel at 13.5% moisture. …A family of four could live about 2 years off the bread produced by one acre of wheat. …One 60-pound bushel of wheat provides about 42 pounds of white flour, 60 to 73 loaves of bread (depending on the size of the loaf and whether the bread is whole wheat), or 42 pounds of pasta. A 30 gram (1.05 ounce) TKW, which translates to 15,200 seeds per pound, is an appropriate minimum TKW for a seedlot. 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. For example, see NebGuide G2044, Calibration of Sprayers (Also Seeders), specifically Problem 10 which illustrates how to calibrate a seeder. After seed germinability has been determined, the seeding rate can be determined. With seeding rate determined, how can we be sure the seeder plants the desired amount? 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 Well, from kswheat.com: ‘One bushel of wheat will yield approximately 42 pounds of white flour. Lodging increases chances for disease, complicates harvest, and negatively affects yield potential. An acre of 660 by 66 international feet. Privacy Policy | Conditions of Use | Product Legal Notice. Taking a germination test is essential to determine the seed viability. Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/ (1-expected stand loss))/ ((seeds per pound)X (% germinaton)) In the range of acceptable seeding rates, shorter wheat products with strong straw can be planted at higher seeding rates with less risk of lodging. Here is some information and average numbers from a friend of mine who grows wheat to sell to folks who make their own flour. If producers use test weight as a seed quality measurement, they should use a seed test weight above 57 lb per bushel. 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 is for winter wheat seeded at an optimum planting date. Consult your seed brand representative for more information on products best-adapted to your geography and the specific agronomic needs of your farm. ©2020 Bayer Group. This range can be as many as 10,000 to as much as 20,000 seeds per pound. of 2,250 pounds of forage DM/acre. If planting is delayed beyond early October, the optimal rate is 150 pounds or 2-1/2 bushels per acre. Another factor affecting seed quality is the protein content of the seed. For irrigation, and especially with late seeding dates, row spacings of 6 to 8 inches are preferred. Wheat has traditionally been planted by the pound. Conversely, a decreased seeding rate results in a decreased number of seeds per head and larger seeds. can be flexed to reach the same yield with fewer plants. S per acre with the drill at planting. More information at http://www.climate.com/disclaimers. 110.7 I.lvo I Dressed (pounds), i (pounds). 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 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). This can affect weed growth, delay maturity, and create an over-reliance on tillering. Seeding rates can be reduced for products that tiller well and are planted timely in good soil conditions. Seed size ranged from a low of 10,700 seeds per pound to a high of 16,400 seeds per pound. Therefore, the yield for 1/4 acre is 1/4 of that, or 2660 pounds. Evaluating seed product yield test data from two or more years and multiple locations can provide a more accurate indication of the potential performance of each wheat product. A few varieties grown in Nebraska have small seed with a lower TKW, but their seed is still suitable for planting. There are several options. Large seed tends to tiller more than small seeds; however, small dense kernels are better than large, light kernels. 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 The expected stand loss can vary between 10 and 20 percent, depending on seedbed conditions. 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). Seed cleaning and sizing is essential to remove straw, chaff, dirt, … To some extent, wheat is inherently capable of compensating for factors that influence yield. 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. The lower rates are most common in drier areas. 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. 2017 Grains and Oilseeds; Crops Acres Seeded Acres Harvested Yield (bu/acre) Production ('000 bu) Farm Value per bu. The change can result in as much as a 200% difference in seeding rate. The amount of protein in the seed, not the protein percentage, is very important to early seedling vigor. On average, there are 22 seeds per head and 5 heads per plant, or 110 seeds per plant. However, variations in seed size and density can lead to great differences in the number of seeds being planted from that pound of seed. Tall wheat products, fields with high yield potential, and over seeding can lead to plants susceptible to lodging. This later seeding date reduces tillering and requires higher seeding rates to compensate for the reduction. 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. Estimated nutrient requirements for grain sorghum based on stage of growth are presented in Table 4. A general goal is to manage fields so each plant produces three tillers. QuickRoots® is a registered trademark of Novozymes. Seed size ranged from a low of 9,000 seeds per pound to a high of 14,100 seeds per pound. ConnectIN™, WestBred and Design® and WestBred® are trademarks of Bayer Group. In the seed-cleaning process, a gravity table will remove the light seed. So how much wheat is a bushel? Pounds of actual N = (1.33 x yield potential) – 13. When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 153% difference in seeding rate. Germination should be found on the seed tag. 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. In addition to these agronomic reasons, calculating optimal seeding rates is important to farmers for economic reasons. Soft White Wheat is used in flat breads, cakes, biscuits, pastries, crackers, Asian-style noodles and snack foods.
