Three planting densities were applied (70, 90 and 110 seeds per 1 m2) with two row spacing (16 and 32 cm), in 4 replications. Soybean Seed Rate Calculator (Fill in numbers in blue boxes) Seed: Seeding rate: Planting: Acres in field Desired stand, thousands of plants per acre Seed drop rate per foot of row Pounds of seed in a unit, if sold by weight Row spacing in inches Inches between seeds Figure 3. what you have just replanted. 2.What is the best row spacing that I should plant my Eagle Forage Soybeans on? Soybean seed yield response to planting date and seeding rate in the upper Midwest. C.O.R.N. Average yield results from 7 soybean row spacing studies published during the last 10 years. Seeding rates based on lbs/acre have little meaning since seed size com-monly varies from 13,000 to 24,000 seeds/pound. Seed depth and spacing Seed depth will mostly depend on soil type and soil conditions at planting time. The increasing width of planters — many are now 60 feet wide — means that splitting rows with additional units makes planters very … Planting the right soybeans for your field is vital to maximizing the profitability of every acre on your farm. Accessibility Accommodation. In the last 10 years, studies show a 3 to 4 bu/acre yield advantage for soybeans planted in drilled narrow rows and 15-inch rows over 30-inch rows. In most situations, 140,000 seeds per acre should result in at least 100,000 plants per acre at harvest. Recommended Population Sizes. Recommended soybean seeding rates in Minnesota. If you plant corn in 20-inch rows soybeans will be planted in 20-inch rows. row spacings in early and late May from 1982 through 1985. Three planting densities were applied (70, 90 and 110 seeds per 1 m 2) with two row spacing (16 and 32 cm), in 4 replications. Research was conducted from 1984 through 1986 at Stoneville, MS, on Sharkey clay (very‐fine, montmorillonitic, nonacid, thermic Vertic Haplaquept) to determine the effect of irrigation and row spacing on seed yield and yield components of early or mid‐May versus late‐June plantings of soybean. Among the largest soybean-producing states there are substantial differences in row spacing practices, with a majority of growers in Illinois, Indiana, Ohio, and Missouri favoring 15-inch spacings, compared to Iowa and Minnesota where soybeans planted in 30-inch rows are much more common (Figure 3). The oil is then refined, blended for different applications, and sometimes hydrogenated. In our 2016 row width study, soybeans grown in 7.5 and 15-inch rows yielded similarly while soybeans grown in 30-inch rows yielded on average 15-20% lower. Other than yield, important factors driving soybean row spacing decisions include equipment and time management issues during the planting season. Agronomy Journal. In June, the soybeans planted in 30-inch rows looked better than the soybeans planted in 15 and 7.5-inch row widths. When your seeds sprout, thin them by cutting the weak seedlings to the ground and spacing the remaining plants 4-6 inches apart. Row spacing and plant density had no statistically significant effect on seed protein concentration and only a small and inconsistent effect on seed size. 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. Soybean growers in the northern latitudes of the United States plant the crop in a wide range of row spacings although there has been a shift toward wider rows (>50 cm) in some Upper Midwest states in the last 5 years. Spacing. 100:696-673. Soybean farmers need to be flexible enough to embrace new technologies and methods. CFAES COVID-19 Resources:   Safe and Healthy Buckeyes   |   COVID-19 Hub   |   CFAES Calendar. … The average relative soybean seed yield among row spacings, ranging from 7- to 30-inches, and averaged across planting rates and all North Dakota site-years is shown in Figure 2. Over the years, the development of soybeans with tolerance to glyphosate, glufosinate, dicamba and 2,4-D have made a huge impact on the way we farm, adding more options to the weed control toolbox from which farmers can work. Newsletter is produced by the Ohio State University Extension Agronomy Team, state specialists at The Ohio State University and the Ohio Agricultural Research and Development Center (OARDC). The closer the row spacing, the higher the yield, but the yield advantage is not great (about 5 to10 %). Soybean seeds need to be planted deep enough to get good seed-to-soil contact and shallow enough that they don’t expend more energy to get out of the ground than necessary—usually about 3 ⁄ 4 to 1 1 ⁄ 4 inches deep. This site designed and maintained by CFAES Marketing and Communications. Most corn planters are set to plant 30-inch rows, and 15-inch soybeans are generally planted by using split-row units placed between the 30-inch rows. Let’s assume a plant stand of 100,000 plants/acre, and one plant is selected for pod count. Phone: 740-223-4043, © 2020 | 2120 Fyffe Road | Room 3 Ag Admin Bldg.

Soybean growers in the northern latitudes of the United States plant the crop in a wide range of row spacings although there has been a shift toward wider rows (>50 cm) in some Upper Midwest states in the last 5 years. 1971 Before heading to the field, consider the conditions you will be planting into. Do not plant early if the soil is excessively cold or wet. Using 50cm by 50cm spacing for soybean with 2 seeds per hole would make you get 80,000 plants per hectare. 4 Grieger, L. 2018. For the soybean monocropping, the row spacing was 0.5 m. The area of each experimental plot was 36 m 2 (6×6 m). C.O.R.N. Consider 15-inch Row Spacing in Soybean. Row spacing is a management decision that often comes up as a priority for achieving high-yielding soybean. For the 15-inch row-spacing treatment, planting population was 180,000 seeds/acre. The 170k seeding rate/30 in. Soybean. If planting 2 inches deep to access uniform moisture, make … CFAES provides research and related educational programs to clientele on a nondiscriminatory basis. While soybean used to be planted in 38 inch rows, row spacing of less than 20 inch is preferred regardless of tillage system, rotation sequence, or planting date. Columbus, OH 43210 Figure 4. | Columbus, Ohio 43210. of soybean seed of four soybean cultivars grown with irrigation at two planting dates and three row spacings in 1971-72, Oakes, North Dakota (9). Soybean relative seed yield with plating rates averaged across row spacings in North Dakota. Source: DuPont Pioneer Brand Concentration Survey. Planting 30 cm row spacing yielded 183 kg ha-1 greater than 61 cm row spacing. Assessing Seed Maturity. Influence of Soybean Seeding Rate, Row Spacing, and Herbicide Programs on the Control of Resistant Waterhemp in Glufosinate-Resistant Soybean - Volume 29 Issue 2 - … Eight soybean seeding rates (starting at 197600 and increasing by 49400 live seed ha-1 increments) and row spacing (30 and 61 cm) were evaluated in 15 North Dakota environments in 2017-2018 to determine plant densities, seed yield, and plant loss, which were compared with soybean producer field data. In Ohio, most soybeans are planted in row widths ≤ 15 inches. Seeding rate. Try to weed your seedbed regularly, especially while the plants are small and easily choked out by weeds. In both years, soybean yield decreased by 0.6 bu/ac per day when planting after mid-May. Soybean germination begins when soil temperatures reach 50°F and moisture is present at the planting depth of 1-1.5 inches. Establishing a good plant stand in the field is important to ensure good crop yields. Eagle Soybean seed comes packaged in 50lb bag lots and the seeding rate of these forage soybeans is 50lbs per acre if rowplanted with a planter or drill. In 2013 and 2014, we conducted a planting date trial at the Western Agricultural Research Station near South Charleston, Ohio. You can save seeds from soybean even if you only grow one plant. White mold development favors cool and wet conditions during soybean flowering. Our trial located at the Western Agricultural Research Station in Clark County was planted the end of May (pictured below). Soybean row width preferences vary greatly across North America, with the 4 largest soybean-producing states showing substantial differences. Soybean can be planted using a hand hoe or the mechanical planter. The study consisted of a series of nine trials conducted during 2008 to 2011 at the NDSU Carrington Research Extension Center and research sites in Prosper and Fargo. At noon at the Shandong site, the red to far-red (R/FR) ratio at the top of the soybean canopy in the intercrop was ~0.4 and the photosynthetic photon flux density (PPFD) was ~740 µmol m −2 s −1 (49% of that of the monoculture soybean plants). The effect of plant population was also significant. Newsletter questions are directed to Extension and OARDC state specialists and associates at Ohio State. The standard spacing requirement for maize is 75cm by 25cm, this is spacing is used when you plant one maize seed per hole. Gaspar, Adam P. January 2019. A dense soybean canopy enhances these conditions, potentially increasing the severity of the white mold. Soybeans grown in narrow rows (≤ 15 inches) tend to out-yield soybean produced in wide row … When saving seeds from soybeans, separate varieties by at least 10-20 feet. C.O.R.N. We connect with people in all stages of life, from young children to older adults. Seed yields from the irrigated early plantings in 1984,1985, and 1986 averaged 3570, 2960, and 2695 kg ha −1, while the later plantings averaged 3115,1900, and 1425 kg ha −1, respectively. Calibration of plants should be based on seed spacing. Soybean seed contains 18–19% oil.

The minimum stand for maximizing soybean yields, and factors that affect this. Without irrigation, yield differences between planting dates were not significant. Best forage performance was obtained when soybean was planted at population levels comparable to those recommended for grain production (100,000 plants/acre). Three planting densities were applied (70, 90 and 110 seeds per 1 m 2) with two row spacing (16 and 32 cm), in 4 replications. The 90% germination value from the seed tag was used to calculate PLS. Plant seeds from late spring to early summer. Calculate Seeds per Foot of Row: How many seeds per foot should I plant? Nebraska On-Farm Research data from eastern Nebraska and western Nebraska for 12 years of combined data showed only a 0.6 bu/ac yield increase when seeding 180,000 soybean seeds/acre compared to 120,000 seeds/acre in 15-inch or 30-inch rows. 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. Figure 1. Percent residue cover after planting ranged from 7 to 15% for … ICM News. Soybean Seeding Rate - Past, Present, and VRS Future. 2Purdue Extension recommends row spacing between 7.5 and 15 inches for maximum soybean yield. Some farmers use 20cm by 20xm; this is quite too close. Test plot data was collected from across the whole state. Factors such as damping-off and pressure from bean leaf beetle are concerns to keep in mind, as well as the possibility of a late spring frost. The effect of plant population was also significant. 5 Mohr, R. 2018. April 2018. Based on the regression equation, the relative yield increases by 0.5% for each inch the spacing is narrower from 30 inches up to the 7-inch row spacing. The relative soybean seed yield among row spacings, ranging from 7- to 30-inches, averaged across planting rates and all North Dakota site-years is shown in Figure 2. The foregoing is provided for informational use only. Soybean Row Spacing and Seeding Rate A study was conducted by NDSU with selected intensive management practices and inputs to examine potential increases in yield and profit. When we talk about the fight against weeds in your soybean fields, herbicides and seeds with herbicide tolerance are often the first things that come to mind. By Laura Lindsey, Crop and Soil Scientist Ohio State University Extension shares the planting time, seeding rates and row widths that achieve higher soybean yields. Rees, Jenny, Laura Thompson, Nathan Mueller. Plots were seeded at either 75k, 105k, 135k, 170k, or 205k pure live seeds (PLS) ac-1. In most cases, there is no difference between 7.5, 10, 15, or 20 inch row spacing and anything less than 30 … Final soybean population depends on germination, emergence, disease and insect pressure, competition from other plants, etc. Although row width preferences vary, a consistent trend across North America is a decline in drilled soybean acres (Figure 3). Soybean row spacings (inches) in the 4 largest soybean-producing states in 2012 as a percent of total acres (USDA-NASS. The standard spacing for soybean is 50cm by 50cm. Final soybean population depends on germination, emergence, disease and insect pressure, competition from other plants, etc. Soybean seeding rates of 90,000 to 120,000 seeds/acre resulted in the highest profitability. The soybean or soya bean (Glycine max) is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses.. 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. Row width should be narrow enough for the soybean canopy to completely cover the interrow space by the time the soybeans begin to flower. The seed was untreated. Adequate soil moisture is the most important factor affecting soybean germination. Newsletter is a summary of crop observations, related information, and appropriate recommendations for Ohio crop producers and industry. As field conditions change or if there are major changes in soil type, evaluations should be conducted again. Row spacing. © 2020 Corteva. The wider the row, the closer are the seeds placed in the row, and this sometimes helps, especially for emergence on … (No studies in sandy soils). For the 15-inch row-spacing treatment, planting population was 180,000 seeds/acre. Licht, Mark. The objective of this study was to evaluate the impact of row spacing and seeding rate on the performance of soybean and to determine whether these management … Soybean Planting Rates The suggested soybean planting rates and final stands … Under good humidity and thermal conditions in 2016 and 2017, the yield of seeds and protein in soybean was 3.3 times higher than if exposed to extreme drought and accompanying high air temperatures in 2018 and 2019. Single Plants: 5" (15cm) each way (minimum) Rows: 5" (15cm) with 5" (15cm) row gap (minimum) Sow and Plant. Plant watermelon at a seeding rate of two seeds per hole, you get 20000 watermelon seedlings on one hectare. If you’re using the square foot gardening method, plant 9 per square foot. The average relative soybean seed yield among row spacings, ranging from 7- to 30-inches, and averaged across planting rates and all North Dakota site-years is shown in Figure 2. 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. Research findings on Minnesota soybean seeding rates. If you’re unsure about which soybean is right for your farm, contact your local Stine Seed Agronomist. Planting depth should be about 1.25 1 to 1.5 inches, depending on soil moisture conditions, and should not exceed 2 inches. Our Ag Calculators are a useful tool to help you calculate your corn seed spacing, drill callibration, soybean replants, and much more. If you count the plant that has 25 pods then you would estimate 35 bu/acre. 1. However, it still is a good idea to stop, dig, and measure to determine if seeds are being placed at the depth and spacing desired. For an accessible format of this publication, visit cfaes.osu.edu/accessibility. It is not uncommon in western Nebraska to see soybean seeding delayed until after irrigated corn is planted, and to do it in 30-inch rows and at 160,000 seeds/ac. Slower germination and compaction can negate the benefits of the earlier planting date. 116 Agricultural Administration2120 Fyffe Road Larger enterprises are more likely to have a dedicated soybean planter; whereas for smaller farms, it may be more practical to share a planter with another crop, such as a drill with wheat or a 30-inch planter with corn. 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. In Ohio, most soybeans are planted in row widths ≤ 15 inches. “By the VC (vegetative cotyledon) stage, with the cotyledons and unifoliates (leaves) fully extended, the plant has already made its decision to branch,” says Casteel. However, the spacing varies, with hand hoes taking on a spacing of (50x25cm) with 3 seeds per hole. The calculator works for soybeans, corn,peanuts and other small-grain tree seeds.
