Row spacing. Plant seeds at a depth of 1-2 inches. Agriculture and Natural Resources 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. However, planting too early (before field conditions are adequate) comes with a risk. Recommended soybean seeding rates in Minnesota. 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. Other than yield, important factors driving soybean row spacing decisions include equipment and time management issues during the planting season. A dense soybean canopy enhances these conditions, potentially increasing the severity of the white mold. Phone: 740-223-4043, © 2020 | 2120 Fyffe Road | Room 3 Ag Admin Bldg. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean can be planted using a hand hoe or the mechanical planter. When you plant two seeds per hole, the inter spacing remains unchanged but the intra spacing is doubled, making 75cm by 50cm. Single Plants: 5" (15cm) each way (minimum) Rows: 5" (15cm) with 5" (15cm) row gap (minimum) Sow and Plant. “So, as you replant over a stand of soybeans at V1 or V2, you take what the original stand has had—with the advantage of time with nodal development and branching—vs. 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. To extract soybean oil from seed, the soybeans are cracked, adjusted for moisture content, rolled into flakes and solvent-extracted with commercial hexane. 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. 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. Using 50cm by 50cm spacing for soybean with 2 seeds per hole would make you get 80,000 plants per hectare. Figure 1. The increasing width of planters — many are now 60 feet wide — means that splitting rows with additional units makes planters very heavy. For the 15-inch row-spacing treatment, planting population was 180,000 seeds/acre. Today row spacing for soybeans seems to be driven by the row spacing for corn. The standard spacing for soybean is 50cm by 50cm. row spacings in early and late May from 1982 through 1985. 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. 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. Soybean Planting Rates The suggested soybean planting rates and final stands … either of the two spacing used, you would get 53,333 maize stands per hectare. | Columbus, Ohio 43210. While soybeans planted in a 15-inch row spacing can generally out-yield soybeans planted in a 30-inch row spacing, disease levels in a 15-inch row spacing can often be high enough that little yield advantage over the 30-inch row spacing might be observed in a high white mold environment. 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. Seeding rate. Each soybean variety was grown in separate test blocks with each variety block containing three replicates of the two spacing treatments. Although every attempt is made to produce information that is complete, timely, and accurate, the pesticide user bears responsibility of consulting the pesticide label and adhering to those directions. Some farmers use 20cm by 20xm; this is quite too close. The row spacing may be from 25 to 90 cm. Seeding rate recommendations for southern, central and northwestern Minnesota, as well as various maturity groups. In the dataset, soybean planting rates ranged from 60,000 to 220,000 pure live seed per acre and row spacings ranged from 7 inches to 30 inches. Before heading out to the field this spring, download a free pdf of the recently revised Ohio Agronomy Guide available here: https://stepupsoy.osu.edu/soybean-production/ohio-agronomy-guide-15th-edition Also, check out other information related to soybean management at http://stepupsoy.osu.edu. Soybean. Introduction Soybean is a versatile crop that can provide many benefits to farming systems in the irrigated areas of southern NSW and northern Victoria. Licht, Mark. In most situations, 140,000 seeds per acre should result in at least 100,000 plants per acre at harvest. The effect of plant population was also significant. 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. Before heading to the field, consider the conditions you will be planting into. Planting the right soybeans for your field is vital to maximizing the profitability of every acre on your farm. Numerous research studies over the past 40 years have evaluated soybean row spacing. Although row width preferences vary, a consistent trend across North America is a decline in drilled soybean acres (Figure 3).
