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. 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. 273 113 12 5 66 Calories per pound. Estimated nutrient requirements for grain sorghum based on stage of growth are presented in Table 4. If planting is delayed beyond early October, the optimal rate is 150 pounds or 2-1/2 bushels per acre. Environmental conditions, including weather and soil fertility, affect stress on stems and vegetative growth. Also, higher yield potential requires higher seeding rates. So how much wheat is a bushel? To some extent, wheat is inherently capable of compensating for factors that influence yield. 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. S per acre with the drill at planting. The heights of wheat products can vary from short and medium-short to tall. 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. Seed Cleaning and Germinability. S per acre in the sulfate form will be adequate for growing wheat on sandy soils. For irrigation, and especially with late seeding dates, row spacings of 6 to 8 inches are preferred. For example, see NebGuide G2044, Calibration of Sprayers (Also Seeders), specifically Problem 10 which illustrates how to calibrate a seeder. How many winter wheat seeds should be planted per acre? 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. So, for example, a field that normally yields 80 bushels per acre would need approximately 93 pounds of N; if 10 pounds were applied at planting, the remaining 83 pounds would be applied in the spring. can be flexed to reach the same yield with fewer plants. Winter wheat seeded late because of weather or following harvest of another crop may require a 30-60% increase in seeding rate. Yields are calculated as 60 pounds per bushel at 13.5% moisture. Seed cleaning and sizing is essential to remove straw, chaff, dirt, stones, weed seeds, and broken, diseased or small shriveled kernels. FieldView™ is a trademark of The Climate Corporation. For a grain yield of 7,500 pounds per acre, sorghum needs approximately 25 inches of water during the growing season. 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. Seeding rates can be reduced for products that tiller well and are planted timely in good soil conditions. 110.7 I.lvo I Dressed (pounds), i (pounds). 350 20 5 216 103 Doien. It also may delay maturity, increase weed competition, and fail to make use of the plant's full yield potential. At a 60 pounds per acre seeding rate, this will deliver 18 seeds to 22 seeds per square foot. With a 25 percent share rent — assuming a net selling price of $4.40 per bushel can be obtained — a producer would need an average yield of 51 bushels per acre to cover variable costs and rent. QuickRoots® is a registered trademark of Novozymes. Delay in planting reduces yield potential and tiller development. There are several options. Climate FieldView™ services provide estimates or recommendations based on models. On average, there are 22 seeds per head and 5 heads per plant, or 110 seeds per plant. Seeding rates tailored to wheat products can help farmers maximize the return on their seed investment while helping mitigate risks associated with under or over seeding. Using rates that are too high may increase costs, result in increased lodging, and possibly reduce yields. Tillering can be manipulated with nitrogen applications. Seed size ranged from a low of 9,000 seeds per pound to a high of 14,100 seeds per pound. Evaluating seed product yield test data from two or more years and multiple locations can provide a more accurate indication of the potential performance of each wheat product. Easy-to-remember approximate or ball-park conversions are often used in general discussion. Seed for planting should be above 85% germination. Lodging increases chances for disease, complicates harvest, and negatively affects yield potential. This is for winter wheat seeded at an optimum planting date. For winter wheat, seeding rates should be increased if planting is delayed to … ($) Total Farm Value ($'000) Figure 1 illustrates average wheat yield per hectare for each typical farm. The nitrogen fertilizer recommendation in South Texas is 2 pounds of nitrogen for each 100 pounds per acre of grain yield. The key is to get an optimum plant population with uniform distribution for efficient use of available resources. A general goal is to manage fields so each plant produces three tillers. Soft White Wheat is used in flat breads, cakes, biscuits, pastries, crackers, Asian-style noodles and snack foods. The highest production of wheat on an acre of land is about 50 bushels (57 last year in Kansas). It becomes quickly apparent that each lot planted at 60 pounds per acre would give vastly different plant populations. Weed management also depends on tiller scouting as some labels require tillers to have two to three leaves before herbicide application. Discuss these factors with your WestBred brand representative to get greater insight on what needs to be purchased and planted in each field. The amount of protein in the seed, not the protein percentage, is very important to early seedling vigor. Spring wheat is seeded at higher population compared to winter wheat. Precise conversions are used for exact technical analysis. Seed Cleaning and Germinability. Seed cleaning and sizing is essential to remove straw, chaff, dirt, … Here is some information and average numbers from a friend of mine who grows wheat to sell to folks who make their own flour. Scouting for tillers should begin when main stems have three full leaves. An acre of 660 by 66 international feet. ©2020 Bayer Group. Wheat has traditionally been planted by the pound. An international pound of 0.45359237 kilograms. 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. If planting is delayed past the optimum time period, the initial stand should be increased by 1 percent for each day planting is delayed. However, variations in seed size and density can lead to great differences in the number of seeds being planted from that pound of seed. Some parts of this site work best with JavaScript enabled. Generally, seed cleaning will add 1 to 2 lb to the seedlot's test weight by removing the small kernels. As mentioned earlier, new crop wheat bids in eastern Arkansas currently range from $4.22 to $4.45. 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. Although yield is only a partial gauge of performance, it reflects the available production technology across farms. Seeding rates are typically expressed as seeds per acre or pounds per acre. 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. To calculate bushels per acre the basic formula is: Bushels/acre = (Harvested dry matter lbs) ÷ Standard lbs/bushel ÷ plot area acres or Yield = “A” lbs ÷ “B” lbs/bushel ÷ “C” acres 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. Larger, denser seeds means fewer seeds planted. These do not guarantee results. 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 ConnectIN™, WestBred and Design® and WestBred® are trademarks of Bayer Group. “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. 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. 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 If we calculate the average yield for all of these crops we find it to be 10,642 pounds per one acre of land. 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. 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). Smaller, lighter seeds can cause over seeding and could lead to lodging, increased disease, and greater input costs. Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/ (1-expected stand loss))/ ((seeds per pound)X (% germinaton)) 267 171 Dozen. Quantifying tillers is important for management practices. Please switch to a supported browser: Chrome, Edge, Firefox, Safari. “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. Purchasing certified seed can help ensure the wheat product is free of weed seed and certain diseases and offers the desired germination percentage. Tall wheat products, fields with high yield potential, and over seeding can lead to plants susceptible to lodging. 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 general, an initial stand of 30 to 32 plants/ft2, which is about 1.3 to 1.4 million plants/acre, maximizes yield potential. Communications Bldg.Lincoln, NE 68583-0918. 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. UNL web framework and quality assurance provided by the, Visit the University of Nebraska–Lincoln, 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. 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 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. Pay close attention to each characteristic in Table 2 as this may require specific modifications in your production practices to achieve the best yield and quality of grain. 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. Bushels. 122.4 Pounds. When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 153% difference in seeding rate. 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. 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. 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). Table 1 lists optimum seeding rates for Nebraska. This browser is no longer supported. 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. 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). 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. Pounit. The broadcast application of 25 lb. Spring wheat is seeded at higher population compared to winter wheat. 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. Large, dense seeds are considered to be of better quality than low test weight seeds. 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. This can affect weed growth, delay maturity, and create an over-reliance on tillering. In general, southern locations had more stems per plant, and wheat planted in high-yielding locations had fewer stems per plant. Seed cleaning and sizing is essential to remove straw, chaff, dirt, … Wheat needs 60 heads to 70 heads per square foot at harvest for full yield potential. Seeding 40 lb of seed with a weight of 15,000 seed per pound has a yield potential of 60 bushels per acre. Instead, seed weight is the critical factor. So a bushel of wheat is 51.9 pounds of dry grain. A few varieties grown in Nebraska have small seed with a lower TKW, but their seed is still suitable for planting. The lower rates are most common in drier areas. Pounds of actual N = (1.33 x yield potential) – 13. 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. All rights reserved. Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/(1-expected stand loss))/((seeds per pound)X(% germinaton)). First, use the operator's manual to set the seeder. 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. Well, from kswheat.com: ‘One bushel of wheat will yield approximately 42 pounds of white flour. …A family of four could live about 2 years off the bread produced by one acre of wheat. In the seed-cleaning process, a gravity table will remove the light seed. For more efficient applications, use 10 to 15 lb. A 30 gram (1.05 ounce) TKW, which translates to 15,200 seeds per pound, is an appropriate minimum TKW for a seedlot.
