soybean planting depth and spacing

Under most conditions, soybeans should be planted between 1 and 1.5 inches deep. The soybean variety was Jindou 37 with a row spacing of 0.3 m 0.5 m and a plant spacing of 0.5 m in a north-south direction. We work with families and children, farmers and businessowners, community leaders and elected officials to build better lives, better businesses and better communities to make Ohio great. 3 Ensure good seed contact with soil moisture contact and avoid planting soybeans deeper than 1.5 inches. This effort has been funded by United Soybean Board. Using a no-till coulter increased corn emergence by 2.8% compared with not using a no-till coulter. Blanch green soybeans in boiling water for a couple of minutes and then plunge them into an ice-water bath. utt@]$$X2t GI30c0A!3#4.Sx=^192`8=jZSgajq3?f\VK'$q7~A!Q_S,a,>0F&s u1D0I/`trB]1 0000231607 00000 n The greatest benefit of planting May 1 to mid-May is canopy closure which increases light interception, improves weed control by shading out weeds, and helps retain soil moisture. How to avoid yield loss with late-planted soybeans. Most farmers find it easier and more reliable to count number of seeds per foot of row or seeds per acre instead of pounds or bushels per acre. 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. A higher population density is needed as soybean planting is delayed into mid-June. In the Farm Journal Test Plots, Ferrie explored the performance of bush beans compared to narrow-row soybeans. It is important to place the seed into the ground at a precise depth and in firm contact with the soil. Each fuzzy pod contains 2 to 4 seeds. Good Products for Growing Soybeans at Amazon: Note: Soybeans should not be eaten raw; they contain trypsin inhibitor which prevents the digestion of proteins. By following strategies for planting soybeans in Minnesota, producers can maximize yield and profits. The best and worst conditions to plant in. 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. Soybean yield: grow 4 to 8 soybean plants per household member. 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. Crop-Tech Consulting has a detailed list on just how low you can go with your planting populations. Increasing the seeding rate by 15 to 30% over desired final plant stand to compensate for plant loss is a good estimate. As farmers gear up and nail down planting depth, row spacing is also a crucial decision that could impact final yields. Plant spacing should be thought of as existing in two directions: 1) within row spacing and 2) between row spacing. Nevertheless, most producers have resisted lowering their planting rates accordingly. 0000013233 00000 n 0000011992 00000 n In Michigan, most farmers plant soybean in 15- or 30-inch row widths. Do not plant soybeans with onion or garlic. And those two have to go together, he says. All Rights Reserved. Decreasing the time to canopy closure can reduce soil moisture loss, increase the ability to control emerging weeds, and increase crop growth rate. If you have a disability and experience difficulty accessing this content request accommodation here. Soybeans grow best in loose, well-drained soil rich in organic matter. Planting too deep will result in poor emergence in the field. Black-seeded beans are used for drying. 0000145303 00000 n (Click an image below to view a high-resolution image that can be downloaded). 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. 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. to 5 bu. 116 Agricultural Administration2120 Fyffe Road For more information, visit https://extension.msu.edu. 0000008382 00000 n Weed control is the primary concern through the early stages of plant growth until the canopy closes around late June. Seed maturity, weather conditions and disease pressure influence whether a fungicide will pay for itself. 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. 0000023501 00000 n Dried, shelled soybeans can be stored in a cool, dry place for 10 to 12 months. A 5 to 10 percent improvement in stand can be achieved with a fungicide seed treatment regardless of seeding An optimal plant population for soybean production is one that maximizes both yield and profitability. Warmer temperatures and a drier forecast are pointing to the possibility of more farmers starting to plant across the Midwest this week. Higher plant populations result in canopy closure earlier in the season and greater light interception. 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. Soybean seed is very sensitive to planting depth, so producers need to be careful and get their crop off to a good start. But gaps of a foot or more between plants mean you need to adjust your planter settings. Seeds range from black to gray, brown, green, yellow, white, and striped. 2023 Meredith Corporation. 0000080119 00000 n Shell dry beans once the pods are fully dry. Soybeans are rarely attacked by a disease. The corn can remove more nutrients than anticipated, leaving levels short for beans. Licht says corn timing is more important than beans, as beans are more resilient. In this case, most of the seed was planted too deep (see photo). However, greater populations do not always result in higher yields. This article was produced by the SMaRT project (Soybean Management and Research Technology). Dr. MarkLichtis an associate professor and extension cropping systems specialist with Iowa State University Extension and Outreach. Across North Dakota and row spacings, the planting rate of about 170,000 pure live seeds (PLS) per acre optimized soybean seed yield. Thin successful seedlings from 4 to 6 inches (1015cm) apart; cutaway thinned seedlings with scissors at ground level being careful not to disturb the roots of remaining plants. If an insecticide/fungicide seed treatment is used, seeding rates can be reduced by 10,000 to 20,000 seeds per acre. 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 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. -102.094189 . 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. Iowa Farm Business Association. 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. New earliest planting date map by countyfor a. Do not soak seed before planting and do not overwater immediately after planting; too moist seeds may crack and germinate poorly. Time is short. 0000223754 00000 n Keep planting beds evenly moist until soybeans have pushed through the soil. Soybean seed depth should be between to 1 inches. Planters typically provide better depth control than drills or air seeders. 0000073092 00000 n An important consideration would be that as plant population increases the available source (light) per plant decreases. Whether to plant longer- or shorter-season varieties. Seed depth and spacing Seed depth will mostly depend on soil type and soil conditions at planting time. 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. Within regions, optimum yield occurred with 180,000 and about 140,000 PLS per acre in eastern and western North Dakota, respectively. 24 - 36 (60-90 cm.) If the plant space is not less than 20cm, working speed could reach 8km/hour. In June, the soybeans planted in 30-inch rows looked better than the soybeans planted in 15 and 7.5-inch row widths. Row width and seeding rates Seeding rates vary with row spacing (Table 2.) Student Focused. Management decisions at soybean planting are critical in setting the crop for success. Space beans about 4-6 inches away from one another with 24 inches between rows. Choosing a seeding rate that is high increases seed cost and may not contribute to a yield increase. Soybeans normally are planted the last two weeks of May, or after corn planting is finished. 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 Planting Depth. 0000115792 00000 n SMaRT is a partnership between MSU Extension and the Michigan Soybean Checkoff program. For an accessible format of this publication, visit cfaes.osu.edu/accessibility. This may require planting deeper than 1.5 inches under dry soil conditions. When planting no-tillage glyphosate-resistant soybeans, such as Roundup Ready, a burn-down herbicide should be used before or at the time of planting if significant weed cover is present. I do all of my research with 15 and 30 inch row spacing comparison since the trends shows that drills probably will disappear in the near future. In most situations, 140,000 seeds per acre should result in at least 100,000 plants per acre at harvest. Soybean plant population in plants per foot of row for different row spacing's. When planting soybeans with a grain drill, it is important to set the drill to the correct depth and spacing. Reconfiguring planting units on no-till drills to improve soybean planting performance, 1998 Childrens Online Privacy Protection Act (COPPA). Recommended seeding rates by Minnesota region and maturity group. better in 15s than they were in 30s, he says. 2022 Farm Journal Test Plots Early Results, Prepare For Planting: This is One of the Biggest Misconceptions About Effectively Combatting Problematic Weeds. 0000012728 00000 n When soybeans are planted in May, a final (harvest) population of 100,000 to 120,000 plants per acre is generally adequate for maximum yield. 3. However, careful planning is required to minimize risks associated with early planting. Plant soybeans in late winter in warm-winter regions. Soybean Planting Time. In Michigan, most farmers plant soybean in 15- or 30-inch row widths. Be sure your conditions are such that reduced row width and greater seeding rates justify the increased cost of seed.
