Time is short. The experts will say the earlier you plant, the better the yield, but there must be adequate ground moisture and the weather should be in a warming trend. Sow soybeans in spring 2 to 3 weeks after the average last frost date when the soil has warmed to at least 60F (16C). Do not plant early if the soil is excessively cold or wet. %PDF-1.4 % Planting in early April carries significant risk, but when successful can produce impressive yields. Having someone watch the planter perpendicular to the direction of travel can help to ensure that the row units maintain contact with the soil. Seeding rate or planting rate refers to the number of soybean seeds planted per acre to attain a certain plant population. Research Institution. At lower populations interplant competition is reduced and each individual plant has a greater opportunity to produce more seeds. Management decisions at soybean planting are critical in setting the crop for success. 0000018731 00000 n Across the U.S., narrow rows ( 15 inches) out-yielded wide rows ( 30 inches) 69% of the time. Issued in furtherance of MSU Extension work, acts of May 8 and June 30, 1914, in cooperation with the U.S. Department of Agriculture. In the Farm Journal Test Plots, Ferrie explored the performance of bush beans compared to narrow-row soybeans. holding off on buying and working with what I have. Ideal seed depth for most conditions is 1 to1 inches, but beans can be planted up to 2 inches deep in sandy soils, or in dry conditions. Particularly with compaction (both surface and sidewall compaction) at planting time. Iowa Farm Business Association. The other factor that could impact row spacing is the need for fungicide and insecticide applications. Planting date and field history are primary considerations when making your selection. Soybean germination starts when the seed imbibes approximately 50% of the seed weight in water, swelling the seed and starting the process of cell division. Table 4. 0000216556 00000 n Seed size varies from one variety to another; therefore one variety may have fewer seeds per pound than another variety. 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. 0000211113 00000 n There are more than 10,000 soybean cultivars. Strategies for success, including guidance on dates, maturities, row spacing and planting depth. window.mc4wp.listeners.push( Seed depth will mostly depend on soil type and soil conditions at planting time. Timely planting allows for soybean to maximize light interception and canopy photosynthesis, increase number of nodes and seeds per unit area, and lengthen the seed filling period. If planting in wide rows (24 to 30 inches), planting rates to reach the optimum yield were about 190,000 PLS per acre. Optimal planting date, seeding rate and row spacing are important to maximize soybean yield and profits. Shell dry beans once the pods are fully dry. 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 . 0000020961 00000 n Grow soybeans with potatoes, cucumbers, corn, strawberries, celery, and summer savory. Soybeans reach maturity at the same time; pull the whole plant and hang it upside down to dry. Soybean plant population in plants per foot of row for different row spacing's. MSU is an affirmative-action, equal-opportunity employer. 0000003237 00000 n Green-shelled or unshelled soybeans will keep in the refrigerator for up to one week. listeners: [], Plant green beans in soil temperatures of 65 degrees or greater. Although there have been concerns surrounding this practice in the past, an understanding of row spacing and soybean growth patterns can play a significant role in integrated weed management. The two plants on the left were planted at least 1 inch deeper than the emerged plants on the right and the seed was placed about 3 inches deep. 2150 Beardshear Hall This site designed and maintained by CFAES Marketing and Communications. At a fixed row width, as plant population increases the plant spacing within the row decreases and interplant competition increases. 0000111762 00000 n 3. One of the challenges that we run into is as farmers are putting the plan together, and you may be thinking weeds on this spectrum, and then somebody over here is thinking about planting and row spacing population. Figure 3. Within regions, optimum yield occurred with 180,000 and about 140,000 PLS per acre in eastern and western North Dakota, respectively. 0000145231 00000 n The bush beans were planted in six maturity groups from a 2.9 up to a 4.0 in both 15 rows and 30 rows. Soybeans grow 12 to 36 inches (30-91cm) tall. 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. Likewise, insecticide seed treatment may be desirable if the field is known for insect pests. In eastern North Dakota trials, 8% of planted PLS per acre did not develop into viable soybean plants. Seeds can be smaller than a pea or as large as a kidney bean. I typically had more trouble calls with soybean emergence from deep placement below 1.25 inches deep. The old method was to use a Hula-Hoop but not many people find it attractive today to drive around with a Hula-Hoop in their truck when they can easily use a meter stick or a measuring tape. On average a farmer in Iowa spends $25 per acre on seeds (Figure 1). Ideally target planting at a depth of 1"-1.25" in optimal soil moisture conditions. 0000159510 00000 n Temperature conditions at planting were considered adequate, average soil t emperatures at 2 inches of depth were in the range of 52 to 57F while average . Recently, a multi-state group of university-based soybean agronomists noticed that the maps that the USDA- Risk Management Agency developed for the earliest planting date that would be allowed for a soybean crop to be insured seemed to have artificial borders not based on real-world risk one example being the stark 10-day difference in earliest planting date on either side of the Red River of the North in Minnesota and North Dakota. 0000002500 00000 n Planting depth surveys revealed that only 20 percent of the fields planted with drills were planted at or near the intended depth. 0000011992 00000 n Seeding rate recommendations for southern, central and northwestern Minnesota, as well as various maturity groups. 0000214510 00000 n At least 50F. 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.

Be sure there is no longer a risk of late freeze or frost by the time of the crops emergence seven to 10 days after planting. 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. 0000218981 00000 n Pods grow 1 to 4 inches (2.5-10cm) long in clusters of three to five. Planting date. 0000021415 00000 n No-till fields will have cool soils longer into the season than tilled fields and commonly will have more seedling disease problems. C.O.R.N. Keep planting beds evenly moist until soybeans have pushed through the soil. Shelled soybeans can be frozen, canned, or dried. 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. However, there are cases where 100,000 plants per acre is not enough. 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. To make shelling easier, drop pods into boiling water for a minute. Each fuzzy pod contains 2 to 4 seeds. For more information, visit cfaesdiversity.osu.edu. With Soybean Planting Populations, How Low Can You Go? The same applies for any known history of Phytophthora, Sudden Death Syndrome, or any other soybean pathogens.

In eastern North Dakota trials, 8% of planted PLS per acre did not develop into viable soybean plants. In June, the soybeans planted in 30-inch rows looked better than the soybeans planted in 15 and 7.5-inch row widths. The proper way to think about seeding rate is the number of plants that need to reach maturity to maximize yield. Regardless of planting date and row spacing, select varieties with good tolerance and/or resistance to Phytophthora root rot. 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. Under most conditions, soybeans should be planted between 1 and 1.5 inches deep. Avoid handling soybeans when they are wet or covered with heavy dew; this may spread fungus spores. 0000013665 00000 n It looks like the bush beans had no response to row spacing, which is also kind of interesting.. Plant spacing should be thought of as existing in two directions: 1) within row spacing and 2) between row spacing. 0000214777 00000 n window.mc4wp = window.mc4wp || { Here is your complete guide to growing soybeans. Ideal seed depth for most conditions is 1 to 1 inches, but beans can be planted up to 2 inches deep in sandy soils, or in dry conditions. They are generally grown in a crop rotation with corn, creating good risk management for both crops by breaking disease, insect, and weed cycles, as well as managing farm workflow. Soybean germination begins when soil temperatures reach 50F and moisture is present at the planting depth of 1-1.5 inches. Soybeans can be planted earlier in warm-winter regions. To have a digest of information delivered straight to your email inbox, visit https://extension.msu.edu/newsletters. Dont test your planter only in the farmyard, but rather with your planter in the ground and at speed. The corn can remove more nutrients than anticipated, leaving levels short for beans. If using a pre-emergence broadleaf herbicide (especially a metribuzin), a depth of 1 to 2 inches deep is recommended to decrease the likelihood that the soybean seedling will take up the herbicide. Residual herbicides are often weed species specific and can help control weeds that have become glyphosate resistant. Green-seed cultivars are considered the most tender and best flavored. Soybean germination begins when soil temperatures reach 50 F and moisture is present at the planting depth of 1-1.5 inches. Late planting under dry conditions requires deeper seed placement to place the seed in contact with moisture. 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. Check out the Michigan Manure Hauler Certification Program! Double, triple and quadruple check to make sure that you are getting your desired seeding depth and seed spacing.
