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. | Columbus, Ohio 43210 | 614-292-6181 Plots were seeded at either 75k, 105k, 135k, 170k, or 205k pure live seeds (PLS) ac-1. © 2020 Corteva. The seed must imbibe (take-in) 50 percent of its weight in moisture in order for the germination process to begin and remain above 20 percent after the seed swells and the seed coat splits. 2Purdue Extension recommends row spacing between 7.5 and 15 inches for maximum soybean yield. Soybeans have a similar growth habit to bush beans, so there’s no caging or staking required. 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. If you count the plant that has 25 pods then you would estimate 35 bu/acre. Spacing. Planting 30 cm row spacing yielded 183 kg ha-1 greater than 61 cm row spacing. When you plant two seeds per hole, the inter spacing remains unchanged but the intra spacing is doubled, making 75cm by 50cm. 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. PIONEER® brand products are provided subject to the terms and conditions of purchase which are part of the labeling and purchase documents. Recommended soybean seeding rates in Minnesota. Introduction Soybean is a versatile crop that can provide many benefits to farming systems in the irrigated areas of southern NSW and northern Victoria. Recommended Population Sizes. The effect of plant population was also significant. 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. Final soybean population depends on germination, emergence, disease and insect pressure, competition from other plants, etc. Row spacing is a management decision that often comes up as a priority for achieving high-yielding soybean. 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. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean and Pulse Agronomy Lab, Department of Plant Science, University of Manitoba. If you’re unsure about which soybean is right for your farm, contact your local Stine Seed Agronomist. The increasing width of planters — many are now 60 feet wide — means that splitting rows with additional units makes planters very … Soybean. Figure 3. Row spacing and plant density had no statistically significant effect on seed protein concentration and only a small and inconsistent effect on seed size. 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. wide rows with a drill on June 12. either of the two spacing used, you would get 53,333 maize stands per hectare. Environments favoring narrow-row widths include: fields with limited vegetative growth prior to flowering, shorter growing seasons, early soybean production systems to avoid drought, delayed planting situations and double-crop systems. The minimum stand for maximizing soybean yields, and factors that affect this. Figure 4. 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. Soybean Planting Rates The suggested soybean planting rates and final stands … The soybean variety, Channel 2402, was seeded in 7.5 in. Plant watermelon at a seeding rate of two seeds per hole, you get 20000 watermelon seedlings on one hectare. The 90% germination value from the seed tag was used to calculate PLS. Some farmers use 20cm by 20xm; this is quite too close. Other than yield, important factors driving soybean row spacing decisions include equipment and time management issues during the planting season. The 170k seeding rate/30 in. The best soybean yields occur on well-drained, but not sandy soils having a pH of 6.5 or above. CFAES provides research and related educational programs to clientele on a nondiscriminatory basis. Each soybean variety was grown in separate test blocks with each variety block containing three replicates of the two spacing treatments. They need to look above and beyond their current cultural practices. 116 Agricultural Administration2120 Fyffe Road 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 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).
