How do you calculate plant population and seeding rate? Ideal planting conditions Soybean has delicate seed, so it benefits when planted about 1.5 inches deep, modestly firmed into the seed furrow, covered by relatively loose soil and into soils that are 60 to 70 degrees Fahrenheit. Final soybean population depends on germination, emergence, disease and insect pressure, competition from other plants, etc. The proper way to think about seeding rate is the number of plants that need to reach maturity to maximize yield. 0000231426 00000 n The 15-inch row seems to be the soybean sweet spot, especially for the Grain Belt. Particularly with compaction (both surface and sidewall compaction) at planting time. There are more than 10,000 soybean cultivars. Htn% x,C ^q'n GR8?)_^>=>?%qo3r4f. 0000080119 00000 n 0000078352 00000 n But we do affect weed control, he says. We know from studies that we've done clear back in 1992, already, that we can pull those bean populations below 120,000 and not affect yield. Issued in furtherance of MSU Extension work, acts of May 8 and June 30, 1914, in cooperation with the U.S. Department of Agriculture. Thank you for stopping by! But take time to take extra care. to 5 bu. Planting date and field history are primary considerations when making your selection. Planting more seeds as insurance seldom pays off in higher yields. Economic yield also must be considered based on seed costs and soybean market prices., NDSU Agriculture Communication - April 26, 2021, Source: Greg Endres, 701-652-2951, gregory.endres@ndsu.edu, Source: Hans Kandel, 701-231-8135, hans.kandel@ndsu.edu, Editor: Ellen Crawford, 701-231-5391, ellen.crawford@ndsu.edu. 0000011992 00000 n Seeding rate or planting rate refers to the number of soybean seeds planted per acre to attain a certain plant population. Adequate soil moisture is the most important factor affecting soybean germination. The units mounted to the center frame of the planter placed the seed at 1.5 inches deep and into moisture while the units mounted to the outer wings planted the seed 1 inch deep and into dry or marginal moisture conditions. In eastern North Dakota trials, 8% of planted PLS per acre did not develop into viable soybean plants. The risks associated with reduced plant populations is that pods form closer to the ground increasing harvest losses and the plant must maintain a high growth rate and leaf area throughout the season to remain competitive with higher populations. April 28, 2022. As a general rule, plant at the shallower end of the range under the following conditions: Early planting High residue conditions Fine-textured soils Moist soils Planting at the deeper end of the range is recommended under the following conditions: Late planting Second, we present planting updates for corn and soybean from our research station managers across the state as our first planting date, 'ultra-early', went into the ground last week. Keep planting beds evenly moist until soybeans have pushed through the soil. Information is provided 'as is' and solely for informational purposes, not for trading purposes or advice. An important consideration would be that as plant population increases the available source (light) per plant decreases. Futures: at least 10 minute delayed. 0000211502 00000 n Dakota Gardener: Finding love in a corn field, Prairie Fare: Spring cleaning can make kitchens safer. utt@]$$X2t GI30c0A!3#4.Sx=^192`8=jZSgajq3?f\VK'$q7~A!Q_S,a,>0F&s u1D0I/`trB]1 Soybean germination begins when soil temperatures reach 50F and moisture is present at the planting depth of 1-1.5 inches. (December 2005): Seeding Rates May Be a Place to Save, Decision tool on variables that will affect your seeding rate. With Soybean Planting Populations, How Low Can You Go? 2023 The minimum stand for maximizing soybean yields, and factors that affect this. Slower germination and compaction can negate the benefits of the earlier planting date. All rights reserved. A versatile legume, soybeans are a common cash crop that produce at least twice as much protein per acre as most other vegetables or grains. 0000041242 00000 n An optimal plant population for soybean production is one that maximizes both yield and profitability. He says as farmers prepare for planting, that's one thing that needs to be considered in their overall crop plans. Soybeans can be, and often are, no-till drilled into previous crop residue, a move that saves on cost without affecting yield. Slower germination and compaction can negate the benefits of the earlier planting date. Licht says seed placement and spacing are not as crucial with soybeans as with corn. of Wisconsin-Madison Extension machinery ag systems specialist and Seth Naeve, UMN Extension soybean agronomist. A decision toolis available to help targeting the final stand of 100,000 plants per acre. 0000215150 00000 n SMaRT is a partnership between MSU Extension and the Michigan Soybean Checkoff program. 0000016118 00000 n If topsoil moisture is lacking, use the deeper placement, but never plant deeper than 1 inches. According to Pioneer, the most common row spacing options for soybeans in the U.S. are 15-inch and 30-inch rows, each accounting for more than one-third of total acreage. He says in some cases, the adjustment to row spacing will impact weed control more than yield. 0000016388 00000 n Timely planting allows for soybean to maximize light interception and canopy photosynthesis, increase number of nodes and seeds per unit area, and lengthen the seed filling period. Adjust your soybean planting equipment as soil and crop residue conditions change and dig up seed frequently to verify that it is placed at the intended depth and into at least 0.5 inch of moist soil. A good method to estimate your stand is to count plants per 10 feet of row, then divide this number by 10 and use Table 2 to determine plants per acre. 3 Ensure good seed contact with soil moisture contact and avoid planting soybeans deeper than 1.5 inches. Rotate beans so that they do not grow in the same location more than every three years. Choosing a seeding rate that is high increases seed cost and may not contribute to a yield increase. Under most conditions, soybeans should be planted between 1 and 1.5 inches deep. callback: cb This site designed and maintained by CFAES Marketing and Communications. Planting soybean seed at the proper depth will produce more uniform stands and higher yields. Figure 3. Planting . The "old" seeding rate guideline (prior to 2006) for optimum planting conditions were: To answer questions about whether current seeding rates are appropriate, numerous studies were initiated in 2003 to update our recommendation. { Green-shelled or unshelled soybeans will keep in the refrigerator for up to one week. It looks like the bush beans had no response to row spacing, which is also kind of interesting.. The University of Minnesota is an equal opportunity educator and employer. C.O.R.N. Also, consider seed size when deciding how deep to plant.

Should new corn growers invest in a grain drill or a corn planter? Table 1. 0000003419 00000 n Maninder Singh, Michigan State University Extension, Department of Plant, Soil and Microbial Sciences - If the plant space is not less than 20cm, working speed could reach 8km/hour. Across North Dakota or by regions, narrow rows (less than 15 inches) consistently provided greatest soybean yield. Row spacing. Timely planting of soybean is critical in achieving high soybean yields. 0000022027 00000 n 0000012728 00000 n By late May, producers will see a yield reduction. Licht says beware of two-year applications. 0000118763 00000 n All rights reserved. One of the challenges that we run into is as farmers are putting the plan together, and you may be thinking weeds on this spectrum, and then somebody over here is thinking about planting and row spacing population. Dont test your planter only in the farmyard, but rather with your planter in the ground and at speed. 0000012838 00000 n Soybean is able to compensate for poor stands by producing more branches resulting in yields comparable to higher plant populations. Soybean extension specialists from across the U.S. have been working together to summarize research related to various management practices. It has previously been an insurance to overseed just to be sure that we received the proper stand since seeds were not very expensive, but who can afford this today? For example, if 120,000 plants per acre is the plant population needed at harvest to maximize yield then more than 120,000 seeds will need to be planted to compensate for plant loss throughout the season. 1-3 seeds Size:24*58*58cm Weight:7.5kg Sowing specifications 6 holes, plant spacing 28cm 7 holes, plant spacing 23cm, 8 holes, plant spacing 20cm, 9 holes, plant spacing 18.5cm, 10 holes, . One should, however, consider planting fullest-season soybean varieties earliest. In this case, most of the seed was planted too deep (see photo). In western North Dakota, the combination of narrow rows (7 to 10 inches) and planting rates of about 150,000 PLS per acre provided optimum yield. If you have a disability and experience difficulty accessing this content request accommodation here. 0000027514 00000 n Some are planting beans before corn, says Licht. Do not soak seed before planting and do not overwater immediately after planting; too moist seeds may crack and germinate poorly. Plant soybeans in full sun; soybeans will tolerate partial shade but the yield will be reduced. It is quite obvious that we may develop new seeding rate recommendations in the future. To contact an expert in your area, visit https://extension.msu.edu/experts, or call 888-MSUE4MI (888-678-3464).

Licht says corn timing is more important than beans, as beans are more resilient. Planting fungicide-treated soybean seed particularly on seed with lower-than-normal germination is a way to ensure adequate stand potential,he says. Soybeans can be planted earlier in warm-winter regions. For the upper Midwest, optimal planting time is generally April 25 to mid-May. })(); Join our gardening family to receive the latest tips. 0000213298 00000 n If an insecticide/fungicide seed treatment is used, seeding rates can be reduced by 10,000 to 20,000 seeds per acre. 0000145204 00000 n Wet weather can delay wheat planting, but issues such as these can be overcome if you factor variety selection, rotations, seeding depth and rate into your planting decisions. Join Jonathan Perkins and Joe Bolte at the Southern IL PFR Site for this latest PFR Report as they evaluate one the planting depth study that they are about . Soybeans, however, can emerge reasonably well from a 2.5 inch depth, if soil crusting is not prevalent during actual emergence from the soil. With conventional tillage glyphosate-resistant soybeans, it is recommended glyphosate be applied 24 to30 days after planting. Soybean stand loss was around 10%. Soybean seeding depth recommendations are at 0.75-1.25 inches for North Carolina, but the right planting depth will depend on field specific conditions at planting. Seeds range from black to gray, brown, green, yellow, white, and striped. Plant soybeans in late winter in warm-winter regions. Rotate soybeans and other legumes to add nitrogen to the soil. How row spacing and other factors affect seeding rates. Soybean (Glycine max L.) is an important leguminous crop [1] which belongs to family Fabaceae. For green shell beans, harvest soybeans when pods are green, full, and plump, usually 2 to 3 inches (5-7cm) long, about half mature. The information presented here, along with any trade names used, is supplied with the understanding that no discrimination is intended and no endorsement is made by Ohio State University Extension is implied. View general guidelines for planting soybean, including: How to select varieties and correct soil deficiencies. Soybeans branch out and can produce high yields even at relatively low plant densities. Plant seeds at a depth of 1-2 inches. At a fixed row width, as plant population increases the plant spacing within the row decreases and interplant competition increases. Summary. However, careful planning is required to minimize risks associated with early planting. Assuming a 90% germination rate and 10% plant attrition during the season, early season stand loss likely reduced final stand in this field to just above 100,000 plants/acre. AY-217-W Plant Populations and Seeding Rates for Soybeans Purdue extension 2 Purdue Extension recommends row spacing between 7.5 and 15 inches for maximum soybean yield. A wide row at a low population is going to take me longer to canopy, Ferrie says. Research has shown that photosynthetic rate is greater and maintained longer in response to larger sink size (seed number) by increased protein levels in leaves and reduced leaf senescence of older leaves. Alterations in plant spacing through row spacing and plant populations have a significant effect on canopy development and yield components. A higher population density is needed as soybean planting is delayed into mid-June. 2023 Meredith Corporation. | Columbus, Ohio 43210 | 614-292-6181 Agriculture and Natural Resources The bush beans were planted in six maturity groups from a 2.9 up to a 4.0 in both 15 rows and 30 rows.

If using a pre-emergence broadleaf herbicide (especially a metribuzin), a depth of 1 to 2 inches deep is recommended to decrease the likelihood that the soybean seedling will take up the herbicide. While shorter season varieties will not gain yield potential with an earlier planting date, a longer-season variety will, adding another couple of nodes of pods when planted earlier compared to later. This is especially true in hitting your yield targets. Farmers who have never used a soybean fungicide seed treatment may want to reconsider this spring, says Dean Grossnickle, a Syngenta agronomic service representative based in central Iowa. For normal planting dates in Michigan and across the Midwest, generally 100,000 to 120,00 plants per acre is enough to achieve maximum yield. The old method was to use a Hula-Hoop but not many people find it attractive today to drive around with a Hula-Hoop in their truck when they can easily use a meter stick or a measuring tape. To obtain a valid estimate of the number of plants per foot of row, make at least 10 random counts throughout the field. In areas prone to pathogens like white mold, plant spacing of up to 30 inches may be preferable. Harvesttotable.com has more than 10 million visitors each year. It takes approximately 125 growing degree day units for soybean seedlings to begin to emerge from the soil, and it might be of use for people trying to time soybean planting to plant approximately 125 heat units earlier than the date of the last 32 degree frost. 0000001976 00000 n You may want to apply a residual herbicide that will remain active in the soil for an extended period of time and act on successive weed germinations. If you're using the square foot gardening method, plant 9 per square foot. Phomopsisinfested a share of soybeans last year, and the inoculum may carry into this years seed lots. As a general rule, plant at the shallower end of the range under the following conditions: Planting at the deeper end of the range is recommended under the following conditions: Soybean seed can be planted up to 2 inches deep in sandy soils. Across North Dakota and row spacings, the planting rate of about 170,00 PLS per acre optimized soybean seed yield, while optimum yield occurred with 180,000 and about 140,000 PLS per acre in eastern and western North Dakota, respectively. Stems and leaves are hairy. This procedure is discussed in more detail in the Michigan State University Extension article, Reconfiguring planting units on no-till drills to improve soybean planting performance.. April 14, 2023 Emmalea Garver Ernest. In most situations, 140,000 seeds per acre should result in at least 100,000 plants per acre at harvest. (Click an image below to view a high-resolution image that can be downloaded). "Consider how to achieve uniform seed placement by looking at factors such as seedbed. Recommended seeding rates vary considerably, but are often around 25% higher than the target plant population. Like any input, the cost must be weighed against yield gains.
