Quentin Tyler, Director, MSU Extension, East Lansing, MI 48824. It was noticed that the total nodes and edges decreased with increasing soil depth, with 0-20 cm recording the highest number of nodes and edges (125 and 58, respectively), followed by 20-40 . For example, if 120,000 plants per acre is the plant population needed at harvest to maximize yield then more than 120,000 seeds will need to be planted to compensate for plant loss throughout the season. } 0000213298 00000 n This article was published by Michigan State University Extension. Soybeans branch out and can produce high yields even at relatively low plant densities. 0000231491 00000 n The "old" seeding rate guideline (prior to 2006) for optimum planting conditions were: To answer questions about whether current seeding rates are appropriate, numerous studies were initiated in 2003 to update our recommendation. (Click an image below to view a high-resolution image that can be downloaded). With these conditions, emergence can typically be expected 2-3 weeks after planting. C.O.R.N. 0000080959 00000 n better in 15s than they were in 30s, he says. Regents of the University of Minnesota. Planting is the most critical management period for soybean production. The University of Minnesota is an equal opportunity educator and employer. Another key thing is that you do not need to increase your seeding rate if you are planting late or if you have to replant. In eastern trials, 8% of planted PLS per acre did not develop into viable soybean plants. Not all of the seed that is planted will germinate or grow to reach plant maturity. 0000223869 00000 n Water regularly during flowering and pod formation. 0000011661 00000 n Planting . Green-seed cultivars are considered the most tender and best flavored. 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. Farmers who have never used a soybean fungicide seed treatment may want to reconsider this spring, says Dean Grossnickle, a Syngenta agronomic service representative based in central Iowa.

How row spacing and other factors affect seeding rates. It looks like the narrow-row beans did respond to narrower rows by 3 bu. Following years of field research on soybean planting rates and/or row spacing, North Dakota State University Extension agronomists are updating their recommendations for establishing soybean stands. Planting in early April carries significant risk, but when successful can produce impressive yields. Plant soybeans at 0.75-1.75 inches deep. Dakota Gardener: Finding love in a corn field, Prairie Fare: Spring cleaning can make kitchens safer. Soybean yield: grow 4 to 8 soybean plants per household member. Residual herbicides require moisture to activate, but not too much, or the chemicals can break down too quickly, so watch the weather report when planning application. The best soybean yields occur on well-drained, but not sandysoils having a pH of 6.5 or above. April 27, 2016. Land Grant. Alterations in plant spacing through row spacing and plant populations have a significant effect on canopy development and yield components. 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. Higher plant populations result in canopy closure earlier in the season and greater light interception. It has previously been an insurance to overseed just to be sure that we received the proper stand since seeds were not very expensive, but who can afford this today? According to Purdue Extension, 67% of Indiana growers plant soybeans one to three weeks earlier than they did 10 years ago. 0000016118 00000 n Planting fungicide-treated soybean seed particularly on seed with lower-than-normal germination is a way to ensure adequate stand potential,he says.

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. 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. Columbus, OH 43210 Copyright 2023 Iowa State University of Science and Technology. 0000006214 00000 n The goal is to get the best results from the potential of the genetics, says Licht. Soybeans are bushy, free-branching, warm-weather annuals. EPA released its draft rule on tailpipe emissions and its drawing fire from biofuels groups. The proper way to think about seeding rate is the number of plants that need to reach maturity to maximize yield. 0000210857 00000 n Research has shown that photosynthetic rate is greater and maintained longer in response to larger sink size (seed number) by increased protein levels in leaves and reduced leaf senescence of older leaves. Recommend seeding rates for seed not treated with insecticide or fungicide is around 170,000 seeds per acre for 7-inch row spacing, 160,000 seeds per acre for 15-inch rows, and 150,000 plants per acre for 30-inch rows.

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. 2150 Beardshear Hall If an insecticide/fungicide seed treatment is used, seeding rates can be reduced by 10,000 to 20,000 seeds per acre. In Michigan, we estimate a yield reduction of 7% when planting soybean on May 31 compared to May 1, with majority of decline occurring after mid-May.

Ideal planting conditions Soybean has delicate seed, so it benefits when planted about 1.5 inches deep, modestly firmed into the seed furrow, covered by relatively loose soil and into soils that are 60 to 70 degrees Fahrenheit. Obviously, both factors can be adjusted to provide optimal plant spacing and typically plant population increases as row spacing decreases. Seven factors for deciding whether to replant after hail or other sources of crop injury. However, careful planning is required to minimize risks associated with early planting. 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. 0000211502 00000 n Soybean is able to compensate for poor stands by producing more branches resulting in yields comparable to higher plant populations. Shelled soybeans can be frozen, canned, or dried. Zucchini. Before heading to the field, consider the conditions you will be planting into.

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. The soybean is native to East Asia, but today most soybean production takes place in the U.S. and South America. Soybean germination begins when soil temperatures reach 50 F and moisture is present at the planting depth of 1-1.5 inches. 0.8 m, 1.4 m, and 2.0 m from the apple trunks and soybean stems at a depth of 20 cm. Seed depth will mostly depend on soil type and soil conditions at planting time. Planting depth should be about 1.25 1 to 1.5 inches, depending on soil moisture conditions, and should not exceed 2 inches. Black-seeded beans are used for drying. USDA shows 8% of the nation's corn crop and 4% of the U.S. soybean crop is now planted. To see all exchange delays and terms of use, please see https://www.barchart.com/solutions/terms. If you must plant deeper than 1.5 inches in order to place the seed into uniform moisture, make sure the variety has an excellent emergence score or long hypocotyl. The other factor that could impact row spacing is the need for fungicide and insecticide applications.
