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. Heavier soils will require greater down-force to ensure that the row units maintain soil contact but be sure to not have it set too high or risk side-wall compaction and smearing. xb```e`b`g``b@ !6(3?^T^NLjY0IsZ$!Y[Zr*xpKKKhc200 0000211113 00000 n better in 15s than they were in 30s, he says. A wide row at a low population is going to take me longer to canopy, Ferrie says. However, the larger cotyledons on large seed are more difficult to pull through a soil crust, so plant large seed shallower when planting into soils prone to crusting. Soybeans can be susceptible to disease, with their closed canopy creating a humid microclimate. Seven factors for deciding whether to replant after hail or other sources of crop injury. (function() { Copyright 2023 Iowa State University of Science and Technology. The plants spread and fill in gaps and perfect stands are not required for maximum yields. 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. 0000112967 00000 n Obviously, both factors can be adjusted to provide optimal plant spacing and typically plant population increases as row spacing decreases. Plant seeds at a depth of 1-2 inches. For early planting, place seed slightly shallower to shorten the time until emergence (related to soil temperature). A good method to estimate your stand is to count plants per 10 feet of row, then divide this number by 10 and use Table 2 to determine plants per acre. Best dates and conditions for planting soybean in Minnesota. Dr. MarkLichtis an associate professor and extension cropping systems specialist with Iowa State University Extension and Outreach. Soybeans reach maturity at the same time; pull the whole plant and hang it upside down to dry. Green-seed cultivars are considered the most tender and best flavored. 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. Slower germination and compaction can negate the benefits of the earlier planting date. 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. Check multiple rows across the planter width. Increased seeding rate will influence yield to a point; however, yield will eventually reach a maximum at which addition of more seed will do nothing to increase yield. If you have wet seedbed conditions or if you have a lot of residue since you are using reduced tillage practices, then it may be an advantage for you to increase your seeding rate to 140,000 seeds per acre. Shibles, R.M., Weber, C.R. https://www.youtube.com/watch?v=ZQ665VJf82E, Registration is free, but required to participate, Fig. 0000231392 00000 n 0000145204 00000 n As a general rule, plant at the shallower end of the range under the following conditions: Early planting High residue conditions Fine-textured soils Moist soils Planting at the deeper end of the range is recommended under the following conditions: Late planting 1998 Childrens Online Privacy Protection Act (COPPA). Licht says corn timing is more important than beans, as beans are more resilient. In dry seedbeds it may be tempting to plant deeper than 1.5 inches. The first step to successful soybean planting and subsequent harvest is seed selection. When you should and shouldnt replant, including a worksheet for making the decision. (NDSU photo). The sowing date was 10 May 2022. . The planting season is hectic. The same applies for any known history of Phytophthora, Sudden Death Syndrome, or any other soybean pathogens. 0000145231 00000 n Planting depth surveys revealed that only 20 percent of the fields planted with drills were planted at or near the intended depth. Management decisions at soybean planting are critical in setting the crop for success. 36 - 48 (90-120 cm.) Newsletter is a summary of crop observations, related information, and appropriate recommendations for Ohio crop producers and industry. 0000015859 00000 n Summary. I do all of my research with 15 and 30 inch row spacing comparison since the trends shows that drills probably will disappear in the near future. There are circumstances where growers may plant deeper than that. Rotate beans so that they do not grow in the same location more than every three years. 0000145303 00000 n Research on plant population has been going on for many years and based on a review of articles beginning in 1980 there seems to be little change in the observations concerning the number of plants per acre needed to maximize yield despite farmers using more conservation tillage practices today. Licht says beware of two-year applications. 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. University of Minnesota Extension discovers science-based solutions, delivers practical education, and engages Minnesotans to build a better future. Seeding rate. Planting date and field history are primary considerations when making your selection. 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. Mike Staton, Michigan State University Extension - Using a no-till coulter increased corn emergence by 2.8% compared with not using a no-till coulter. Soil types and conditions will impact closing wheel performance. 0000080119 00000 n Blanch green soybeans in boiling water for a couple of minutes and then plunge them into an ice-water bath. For more information, visit https://extension.msu.edu. Guide to evaluating crop damage and deciding whether to replant. For an accessible format of this publication, visit cfaes.osu.edu/accessibility. Plant soybeans at 0.75-1.75 inches deep. Time is short. An important consideration would be that as plant population increases the available source (light) per plant decreases. } 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. 0000020961 00000 n The yield difference between 30-inch rows and rows 20 inches or less can be as much as 2.9 bushels per acre, but there are other considerations. C.O.R.N. For green shell beans, harvest soybeans when pods are green, full, and plump, usually 2 to 3 inches (5-7cm) long, about half mature. %PDF-1.4 % It is quite obvious that we may develop new seeding rate recommendations in the future. Historically, in Farm Journal Test Plots, Ferrie says he has seen a positive ROI about 50% of the time a fungicide was used in soybeans. 2023 Ideally target planting at a depth of 1"-1.25" in optimal soil moisture conditions. 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. For technical support please contact the CFAES Helpdesk. Strategies for success, including guidance on dates, maturities, row spacing and planting depth. Best dates to plant on to maximize yield potential. Crop-Tech Consulting has a detailed list on just how low you can go with your planting populations. There are more than 10,000 soybean cultivars. Spacing. Using spring-based down-force systems is fine but be sure to make sure that you adjust down-force to make sure that the row unit gauge wheels maintain contact with the soil at speed. 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. 0000014216 00000 n Reference to commercial products or trade names does not imply endorsement by MSU Extension or bias against those not mentioned. With todays seed treatments we are seeing planting earlier that ever before, says Licht. Higher plant populations result in canopy closure earlier in the season and greater light interception. Fungicide treatments are especially helpful if planting early in the spring, as wet, cool soil conditions can add to the risk of seedling disease. Prior to 2006, our recommendations were conducted prior to the use of roundup ready varieties. Good Products for Growing Soybeans at Amazon: Note: Soybeans should not be eaten raw; they contain trypsin inhibitor which prevents the digestion of proteins. How to avoid planting in bad weather and soil conditions. If planting in wide rows (24 to 30 inches), planting rates to reach the optimum yield were about 190,000 PLS per acre. MSU is an affirmative-action, equal-opportunity employer, committed to achieving excellence through a diverse workforce and inclusive culture that encourages all people to reach their full potential. 0000002500 00000 n April 14, 2023 Emmalea Garver Ernest. The team concluded that with aftermarket closing wheels, down-force pressure made less of an impact on corn emergence in a wet year providing uniform emergence regardless of pressure. window.mc4wp.listeners.push( The primary reason for this advantage is light utilization; canopy closure is approximately 15 days earlier in 15-inch rows compared to 30-inch rows. For normal planting dates in Michigan and across the Midwest, generally 100,000 to 120,00 plants per acre is enough to achieve maximum yield. 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. To have a digest of information delivered straight to your email inbox, visit https://extension.msu.edu/newsletters. MSU is an affirmative-action, equal-opportunity employer. While numerous field research studies and trials have worked to determine the optimal row spacing for soybeans, Pioneer says previous studies have found that soybean yield potential is often greater with row spacings narrower than 30 inches. There should be approximately 2" between plants. At lower populations interplant competition is reduced and each individual plant has a greater opportunity to produce more seeds. I am recommending farmers to try to see if they can manage a lower seeding rate (Table 4). Examples include planting to soil moisture with limited rainfall in the forecast or planting below a pre-emergence . 0000001976 00000 n We connect with people in all stages of life, from young children to older adults.
