spring wheat seeding rate per acre

His research showed that using a common North Dakota seeding rate of 1.5 bu./acre of two varieties with very different kernel weights — 15 grams per 500 kernels for one and 20 grams per 500 kernels for the other — could result in a difference of up to 400,000 seeds per acre. Delay in planting reduces yield potential and … A variety that tillers well requires a lower seeding rate than one that does not. Alpha Lattice with three replications. Farmers calculate corn and soybean rates by seed count and should do the same for small grains. FieldView™ is a trademark of The Climate Corporation. Farm Progress is part of the Informa Markets Division of Informa PLC. As an example, Albany, which tillers profusely at low seeding rates, had an optimum seeding rate across all environments of 1.06 million seeds per acre, while Kuntz, the variety that produced the lowest number of tillers at a given seeding rate in the study, had an optimum of 2.03 million seeds per acre. Discuss these factors with your WestBred brand representative to get greater insight on what needs to be purchased and planted in each field. This browser is no longer supported. This can affect weed growth, delay maturity, and create an over-reliance on tillering. Note that it is important to determine kernel weight and know the germination status of your seed. Spring wheat is seeded at higher population compared to winter wheat. Dryland fields in the Panhandle can have their seeding rate lowered to 45 lb/acre. Seeding depth can be as deep as 1½ inches, but a depth of only ½ to ¾ inch will increase the rate of emergence, establishment and forage production potential. Areas with more moisture may use a heavier rate and adjusted planting dates. All rights reserved. 28 -30. For a wheat variety like Superb, that would equate to about 2.35 bushels per acre. Seeding Rate Calculator. Germination should be found on the seed tag. Lower seeding rates can be used on most productive ground; higher rates are needed on moderate to poorer quality soils. Data from 2013 to 2015 including 12 hard red spring wheat products planted across Minnesota and North Dakota demonstrates tillering can be predictive. Lines and paragraphs break automatically. For cover crop, 40 lbs./acre is good rate for new growers. If drilling, approximately 75 pounds per acre should do. Use this calculator to decide how much seed you need to plant to obtain the desired plant population and calibrate your seeder. Furthermore, this supports the recommendation of using a slightly higher seeding rate when planting is delayed beyond the optimum window.”. If you’re using a grain drill the range is about 21 to 28 seeds per row foot. The higher wheat and cattle prices will affect decisions for fall wheat planting. 2. 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. Example: 25 (plants per sq. 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. Good seed will have a germination of 90-95% and seed mortality is … Averaged across all environments and varieties, the highest yield was obtained at the 1.40 million seeds per acre seeding rate. In other words, you would need to plant 64 pounds of this product per acre to achieve a 25 lbs./acre PLS seeding rate. 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. Mueller and fellow SDSU Extension agronomists have been researching spring wheat seeding rates since 2010. The optimum stand is less than hard red spring wheat (HRSW) because the crop will have more opportunity to tiller … Seeding rates (1, 1.5, 2, 2.5 million seeds per acre). With spring wheat, a yield loss of about 1/2 bushel per acre per day can be expected if planting occurs after April 15. If broadcasting, do so at a rate of approximately 100 pounds per acre. Wheat has traditionally been planted by the pound. Tall wheat products, fields with high yield potential, and over seeding can lead to plants susceptible to lodging. Based on predictive equations, the optimum average seeding rate was 1.47 million seeds per acre. This range can be as many as 10,000 to as much as 20,000 seeds per pound. Clearfield® is a registered trademark of BASF Corporation. 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. The heights of wheat products can vary from short and medium-short to tall. For example, the seeding rate for wheat in western Kansas ranges from 40 to 60 pounds per acre, and increases from 50 to 60 pounds per acre and 60 to 75 pounds per acre in central and eastern areas, respectively. This site is operated by a business or businesses owned by Informa PLC and all copyright resides with them. The best seeding rate will vary by variety and soil’s productivity. How heavy should the new spring wheat varieties be seeded? Privacy Policy | Conditions of Use | Product Legal Notice. Seeding rates for dryland fields in the Panhandle for this type of management can be lowered to 90 lb/acre. SEED NUMBERS: Wheat seedlings emerge in the spring. “Wheat intended for pasture should be seeded at a high rate — about 120 pounds of seed per acre — and planted early,” says Jim Shroyer, Kansas State University Extension agronomist. In addition to these agronomic reasons, calculating optimal seeding rates is important to farmers for economic reasons. Seed cleaning and sizing is essential to remove straw, chaff, dirt, … Ask your wheat seed dealer about seed counts for the wheat product you purchase. All seed was treated, but the chemicals and rates used varied according to the preferences of the originating organization. Similarly, if wheat is planted early, seeding rates must be adjusted down, by at least 25% if seeding 10 days ahead of normal. Environmental conditions, including weather and soil fertility, affect stress on stems and vegetative growth. Purchasing certified seed can help ensure the wheat product is free of weed seed and certain diseases and offers the desired germination percentage. Informa Markets, a trading division of Informa PLC. Seed cleaning and sizing is essential to remove straw, chaff, dirt, … Seeding shorter statured varieties like Rollag and Linkert, on the other hand, at seeding rates higher than 1.4 million seeds per acre, will probably result in a positive economic return, especially for environments that are low to moderate for yield. Sometimes recommendations for good wheat stands are based on seedlings per foot of row. Alfalfa: 60: 10-20: Medium Red Clover : 60: 10-15: … Seeding rates can be reduced for products that tiller well and are planted timely in good soil conditions. Environment plays a significant role in the optimum seeding rate. 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 bottom lineIn higher yielding environments and when planting a variety that tillers well with reasonable straw strength, seeding rates greater than about 1.4 million seeds per acre will not return extra value to your operation, Ransom says. The number of heads per pure live seed planted decreases, with increased seeding rates. 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. Seeding Rate (lbs/acre) = ((desired stand in plants per acre)/(1-expected stand loss))/((seeds per pound)X(% germinaton)). So this 50-lb. 25 lbs./acre divided by 0.39 = 64 lbs./acre of crimson clover. It becomes quickly apparent that each lot planted at 60 pounds per acre would give vastly different plant populations. 2. The first consideration involves understanding how much difference there can be between seed lots in the number of seeds per pound. OSU recommends a 60 lb/acre seeding rate for grain-only production when planted during that optimal mid-October time. WestBred seed suppliers running the ConnectIN Wheat Insight System can offer seed counts for each product along with Optimal Seeding Rate recommendations. A general goal is to manage fields so each plant produces three tillers. Normal seeding rates are considered to be 1.5 million seeds/acre on clay loam or lighter soils, and 1.8 million seeds/acre on heavy clay soils. Five things that Joel Ransom, NDSU Extension agronomist, says the researchers learned were: 1. Generally, this is equivalent to approximately 1 bushel rye seed/acre for crop production. All rights reserved. If the desired stand was around one million seeds per acre, then the first … Remember that each variety and lot may have a different number of seeds per pound. 4. Once planting begins, make sure the seeds are 1 to 1½ inches in depth. Legumes: Per BU. Seeding different varieties at the same pounds per acre can result in significantly different plant populations. “Conversely, for lower yielding environments, there may be an economical advantage to increasing the seeding rate over the general recommendation of 1.4 million seeds per acre. Seeding rate (pounds of live seed per acre) Seeding date* Depth; Spring Fall; Grasses; Barley: Annual, cool-season grass: Broadcast:110 to 140 Drilled:80 to 110 : Sept 15 to 30: 1 to 2 inches: Bermudagrass: Perennial, warm-season grass: 20 to 30 bushels per acre sprigged 30 bushels broadcast: March to May : 1 to 2 inches. Smaller, lighter seeds can cause over seeding and could lead to lodging, increased disease, and greater input costs. These do not guarantee results. Winterhardiness,yielding ability, straw strength, height, grain quality, andresistance to Hessian fly and diseases (particularly Septoria leaf andglume blotch, powdery mildew, and leaf rust) all must be consideredwhen choosing a variety. 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. ft.) x 43 (g) x 10 ÷ 85 (per cent survival) = 126 lb. Although the varieties used in this study were not the most recent or most popular varieties, they had known traits and genes that helped the researchers help us develop models to predict an optimum seeding rate for new varieties with those traits and genes. Lodging increases chances for disease, complicates harvest, and negatively affects yield potential. Varieties differed in their response to seeding rate. "This research showed a seeding rate of 1.2 million pure live seeds (PLS) … If planting is delayed past the optimum time period, the initial stand should be increased by 1 percent for each day planting is delayed. Treated seeds are larger than non-treated seeds, a factor in determining your seeding rate. Suggested planting rates for Kansas crops. The optimum seeding rate varied from 600,000 seeds per acre for Sabin to 2.0 million seeds per acre for Kuntz. Climate FieldView™ services provide estimates or recommendations based on models. (LBS.) “This substantial difference strongly suggests the importance of a variety-specific seeding rate recommendation,” Ransom says. For best results, oat should be drill-planted on a conventionally tilled seedbed at a seeding rate of 80 to 100 pounds of seed per acre. Seeding rate ranges for the state are recommended between 1.6 million and 2.1 million seeds per 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. increase seeding rate by 400,000 seeds/ac above your normal seeding rate. In 2019, Seahawk soft white spring wheat was planted in a trial (results in Figure 1) with the following treatments: Starter fertilizer (with and without). Also remember to adjust your planter. Number 8860726. The optimum stand of winter wheat is 900,000 to 1,000,000 plants per acre or 21 to 23 plants per square feet. Consult your agronomist, commodities broker and other service professionals before making financial, risk management, and farming decisions. Informa PLC's registered office is 5 Howick Place, London SW1P 1WG. >65 bu per acre), seeding rates need not be increased to achieve higher yields, but in fact, they should probably be reduced slightly,” Ransom says. QuickRoots® is a registered trademark of Novozymes. Germination and mortality are based on seed tests. Those who may still be planting by pounds or bushels per acre may want to consider a different approach. 3. Nitrogen rates (0, 45, 90, 135, 180 pounds per acre). No single soft red winter wheat variety has all the desirablecharacteristics; rather, each has certain advantages. Conversely, a decreased seeding rate results in a decreased number of seeds per head and larger seeds. Tillering can be manipulated with nitrogen applications. Heads per plant, or tillering, is a trait affected by environmental conditions, including soil fertility, planting date, and agronomic practices such as seeding rate. If you're still seeding wheat by "about two bushels per acre", it's time to revisit your seeding strategy. Seed Cleaning and Germinability. Varieties differed in their response to seeding rate. 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. 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.
