If the plant space is not less than 20cm, working speed could reach 8km/hour. 0000013233 00000 n Row spacing. The other factor that could impact row spacing is the need for fungicide and insecticide applications. By late May, producers will see a yield reduction. Read the detailed report on planting date. Water regularly during flowering and pod formation. EPA released its draft rule on tailpipe emissions and its drawing fire from biofuels groups. Recommended seeding rates by Minnesota region and maturity group. "When lowering populations, treat soybean planting more like you treat corn planting," he advises. Some are planting beans before corn, says Licht. 0000118763 00000 n Prairie Fare: What would you call these foods? Need to increase seeding rate if seed bed conditions are not optimal, Increase seeding rate as row spacing decreases, Use lower seeding rates in addition to tolerant varieties, Higher seeding rates are needed if not treated with a fungicide seed treatment, Higher seeding rates are needed if germination is low, Higher seeding rates are needed if speed is too high due to poor seed placement. Table 2. Guide to evaluating crop damage and deciding whether to replant. Warmer temperatures and a drier forecast are pointing to the possibility of more farmers starting to plant across the Midwest this week. And those two have to go together, he says. focused on planter settings and soybean planting considerations, Before applying manure, check the Runoff Risk Advisory Forecast, Starter fertilizer for corn: 5 things to know. Under most conditions, soybeans should be planted between 1 and 1.5 inches deep. Once planting season begins, it is of utmost importance to follow best practices for safety and environmental stewardship. If you're using the square foot gardening method, plant 9 per square foot. In determining when to put seeds in the ground, soil condition and weather trump date. Soybean plant population in plants per foot of row for different row spacing's. The other variable farmers sometimes forget, according to Ferrie, is the correlation between row spacing and weed control. Prairie Fare: Can you name the three ways to thaw food safely? This work resulted in the NDSU Extension publication Soybean Response to Planting Rates and Row Spacings in North Dakota (A1961). Grow soybeans with potatoes, cucumbers, corn, strawberries, celery, and summer savory. Optimum planting depth under good seed bed conditions is from 1 to 1 inches. event : evt, 0000231392 00000 n In dry seedbeds it may be tempting to plant deeper than 1.5 inches. USDA shows 8% of the nation's corn crop and 4% of the U.S. soybean crop is now planted. soybean fungicide seed treatment may want to reconsider this spring, Identifying and managing sudden death syndrome in soybeans, Helena introduces two new sustainable brands, XtremeAg farmers share wins and lessons of 2022 growing season, plans for 2023. Particularly with compaction (both surface and sidewall compaction) at planting time. What about the whole story on seeding rate versus economics? 0000223869 00000 n The best soybean yields occur on well-drained, but not sandysoils having a pH of 6.5 or above. A corn planter usually does a better job than a grain drill, though modern drills have much better depth control than older drills. Choosing a seeding rate that is high increases seed cost and may not contribute to a yield increase. Historically, in Farm Journal Test Plots, Ferrie says he has seen a positive ROI about 50% of the time a fungicide was used in soybeans. An optimal plant population for soybean production is one that maximizes both yield and profitability. This is why agronomists recommend planting soybeans into at least 0.5 inch of moist soil. Futures: at least 10 minute delayed. } No-till fields will have cool soils longer into the season than tilled fields and commonly will have more seedling disease problems. 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. 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. Emergence and eventual establishment of a soybean stand varies from year to year because of many factors (Table 1). better in 15s than they were in 30s, he says. According to Purdue Extension, 67% of Indiana growers plant soybeans one to three weeks earlier than they did 10 years ago.

There are more than 10,000 soybean cultivars. For early planting, place seed slightly shallower to shorten the time until emergence (related to soil temperature). Planting depth should be 1/2" to 1". Not all of the seed that is planted will germinate or grow to reach plant maturity. Proper Planting Depth for Corn & Soybeans Pioneer Seeds United States 22.2K subscribers Subscribe 13 Share 4K views 3 years ago Pioneer Field Agronomist Jesse Moch shows you the proper. 0000210857 00000 n Ideal seed depth for most conditions is 1 to 1 inches, but beans can be planted up to 2 inches deep in sandy soils, or in dry conditions. Soybeans are not frost-tolerant. View general guidelines for planting soybean, including: How to select varieties and correct soil deficiencies. Over several years, research across Midwestern states has consistently shown that soybean planted in narrow rowsless than 30-inchhas a yield advantage when compared to rows greater than 30-inches. 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. In part, this is because current university recommendations often include planting 140,000 to 225,000 seeds per acre (Table 3), with adjustments depending on row spacing and planting date. Spacing. 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. The goal is to get the best results from the potential of the genetics, says Licht. Slower germination and compaction can negate the benefits of the earlier planting date. 0000223942 00000 n Best dates and conditions for planting soybean in Minnesota. 3. Reference to commercial products or trade names does not imply endorsement by MSU Extension or bias against those not mentioned. Check out the Michigan Manure Hauler Certification Program! Planting more seeds as insurance seldom pays off in higher yields. Be sure your conditions are such that reduced row width and greater seeding rates justify the increased cost of seed. Like any input, the cost must be weighed against yield gains. On average, producers can achieve 4.5 bu./acre more yield by planting soybean in 15 inch vs. 30 inch row spacing across all seeding rates. If an insecticide/fungicide seed treatment is used, seeding rates can be reduced by 10,000 to 20,000 seeds per acre. Seeding rate and number of viable plants are influenced by many factors. A low plant population can be competitive with higher plant populations as long as the plant population is uniformly distributed in the field. (NDSU photo). and warming to ensure adequate soil temps is ideal. Maninder Singh, Michigan State University Extension, Department of Plant, Soil and Microbial Sciences - This is true when large seed is planted in coarse-textured soils. Soybeans grow best where the daytime temperature averages in the 70sF (21C). Since there is good evidence that soybean is already source limited, any more reduction on source capacity would come at a cost of yield per plant. 24 - 36 (60-90 cm.) At lower populations interplant competition is reduced and each individual plant has a greater opportunity to produce more seeds. Soybeans grow best in loose, well-drained soil rich in organic matter. (800) 262-3804, Iowa State University 0000023066 00000 n Increasing the seeding rate by 15 to 30% over desired final plant stand to compensate for plant loss is a good estimate. 0000080119 00000 n 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. Final soybean population depends on germination, emergence, disease and insect pressure, competition from other plants, etc. Examples include planting to soil moisture with limited rainfall in the forecast or planting below a pre-emergence . Shibles, R.M., Weber, C.R. How row spacing and other factors affect seeding rates. Other than yield, the most important factor driving soybean row spacing practices are equipment and time management during the planting season, said Mark Jeschke, Pioneer agronomy manager. 0000112967 00000 n 0000231426 00000 n Planting into a poor seedbed, use of poor quality seed, inaccurate planter adjustment, planting too fast, soil crusting, soil moisture extremes, and environmentally induced plant injuries such as herbicide drift, pathogens, insects, hail, or frost all reduce plant population requiring a greater seeding rate. Sow soybean seeds 1 to 2 inches (2.5-5cm) deep, 2 to 4 inches (5-1ocm) apart in rows 24 to 30 inches (61-76cm) apart. However, depth control on drills and air seeders equipped with gauge wheels mounted on single disk openers can be greatly improved. How to Plant, Grow, and Harvest Cucumbers, Cucumber Varieties: Best Bets and Easy-to-Grow, How to Plant, Grow, and Harvest Hot Peppers, Care and Feeding Vegetables in Containers, Grow Bags: Best Vegetable Varieties to Grow, Balcony and Rooftop Vegetable Garden Basics. Then the roots were cleaned and the . 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. The apple and soybean roots were collected separately. 2 - 4 (5-10 cm.) All https://www.barchart.com/solutions/ is provided by Barchart Solutions. 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. 0000075510 00000 n Soybeans grown in narrow rows ( 15 inches) tend to out-yield soybean produced in wide row width (30 inches) due to increased sunlight interception in narrow rows. 0000016388 00000 n Slower germination and compaction can negate the benefits of the earlier planting date. The "new" seeding rate guideline for optimum planting conditions are: It is not a secret that planting 20 to 30% more seed than we really need is an expensive insurance. 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 To see all exchange delays and terms of use, please see https://www.barchart.com/solutions/terms. Keep planting beds evenly moist until soybeans have pushed through the soil. 0000080959 00000 n I visited a field where a planter had failed to place the seed at the correct depth. Taking time to check planting depth is important regardlessof the planting equipment used. The number of seeds planted per foot of row is based on 85 percent germination and an optimum population of approximately 150,000 plants per acre for full-season beans. But we do affect weed control, he says. Having enough down-pressure is key to getting good soil contact with row unit, as under heavy residue conditions, the row-unit would otherwise just ride above and not through the residue, wasting seed. Land Grant. Do not plant early if the soil is excessively cold or wet. Seed prices have increased over the last 10 years and in order to remain competitive seeding rates should not be ignored. Beans will compensate for plant spacing and other ills. 0000212661 00000 n Soybeans can be grown in containers 8 inches deep, the space required for a useable crop makes soybeans a poor choice for container growing. 0000003604 00000 n While for others, its hard for them to wrap their heads around that change. For larger farms he suggests running two planters simultaneously. If topsoil moisture is lacking, use the deeper placement, but never plant deeper than 1 inches. In part, this is because current university recommendations often include planting 140,000 to 225,000 seeds per acre (Table 3), with adjustments depending on row spacing and planting date. Newsletter questions are directed to Extension and OARDC state specialists and associates at Ohio State. In both years, soybean yield decreased by 0.6 bu/ac per day when planting after mid-May. After more than 30 experiments across the last 3 years we have seen very consistent data and even though we will finalize the studies in 2006 I have decided to share some of the data that we have found. (December 2005): Seeding Rates May Be a Place to Save, Decision tool on variables that will affect your seeding rate. For technical support please contact the CFAES Helpdesk. Soybean row spacing used by growers varies widely across the U.S. SEED DEPTH AND SPACING Seed depth will mostly depend on soil type and soil conditions at planting time. Under most conditions, soybeans should be planted between 1 and 1.5 inches deep. If aftermarket closing wheels are something that you are interested in pursuing, buy a handful to test, rather than purchasing enough for your planter. One should, however, consider planting fullest-season soybean varieties earliest. Table 1. Ideal seed depth for most conditions is 1 to 1 inches, but beans can be planted up to 2 inches deep in sandy soils, or in dry conditions. Weed control is the primary concern through the early stages of plant growth until the canopy closes around late June. The expectation would be that narrow row spacing and increased plant population would improve light interception and that would then have a cascade effect, increasing crop growth rate and potentially improving seed production. Soybeans are not frost-tolerant. 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. Strategies for success, including guidance on dates, maturities, row spacing and planting depth. Check out the MSU Fruit & Vegetable Crop Management Program! Jarrod O. Miller, Extension Agronomist, jarrod@udel.edu. Soil types and conditions will impact closing wheel performance. Soybean Planting Time. Soybean Soybean planting Planting is the most critical management period for soybean production. You need to look at your planting window and your harvest window and determine what works best for you. Heavier soils will require greater down-force to ensure that the row units maintain soil contact but be sure to not have it set too high or risk side-wall compaction and smearing. Soybeans are also sensitive to certain herbicide residues, so care should be taken to ensure carryover will not affect next years crop. Regents of the University of Minnesota. Seed size varies from one variety to another; therefore one variety may have fewer seeds per pound than another variety. Prior to 2006, our recommendations were conducted prior to the use of roundup ready varieties. Should new corn growers invest in a grain drill or a corn planter? ); Do not plant early if the soil is excessively cold or wet. 48 - 60 (90-150 cm.) Mulch when the soil warms to greater than 60F (16C) to conserve soil moisture. Soybean germination begins when soil temperatures reach 50F and moisture is present at the planting depth of 1-1.5 inches. When planting soybeans with a grain drill, it is important to set the drill to the correct depth and spacing. Planting Date Decisions. Mulch to conserve soil moisture once the soil has warmed. Decreasing the time to canopy closure can reduce soil moisture loss, increase the ability to control emerging weeds, and increase crop growth rate. Soybean Planting Research Updates. It is increased if the field is fertile enough and well provided with moisture, and if there is a lack of moisture, it is reduced. To contact an expert in your area, visit https://extension.msu.edu/experts, or call 888-MSUE4MI (888-678-3464). It looks like the narrow-row beans did respond to narrower rows by 3 bu. This is especially true in hitting your yield targets. The variety had an excellent emergence rating and many of the plants were able to finally emerge, but with lower energy reserves and vigor than the plants that were planted at the correct depth. Summary. If the field was previously planted to corn, check phosphorous and potassium levels. Planting . The term plant population refers to the number of soybean plants per acre. The team concluded that with aftermarket closing wheels, down-force pressure made less of an impact on corn emergence in a wet year providing uniform emergence regardless of pressure. However, low plant populations may result in lower pod height, lodging of lateral branches, and higher weed populations, all of which may result in harvest losses.
