April 27, 2016. 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. In this case, most of the seed was planted too deep (see photo). Soybeans, like other legumes, set up a mutual exchange with soil microorganisms called nitrogen-fixing bacteria to produce nitrogen compounds used by the plant. Management decisions at soybean planting are critical in setting the crop for success. Recommended seeding rates by Minnesota region and maturity group. If planting no-till, be sure the seed are in contact with the soil, not just the residue on the soil surface. Determination of the plant population is essential after damage by hail, diseases, or herbicides. Improved planter technology and increased seed quality have resulted in more accurate plant populations and stand establishment that are only slightly reduced from the seeding rate, and do not require over seeding by 20 to 30%. The University of Minnesota is an equal opportunity educator and employer. On average a farmer in Iowa spends $25 per acre on seeds (Figure 1). High Precision of Sowing: The qualified data reaches more than 90% with coherent sowing depth and distance; 4. This work resulted in the NDSU Extension publication Soybean Response to Planting Rates and Row Spacings in North Dakota (A1961). They are generally grown in a crop rotation with corn, creating good risk management for both crops by breaking disease, insect, and weed cycles, as well as managing farm workflow. Soybean costs ($ per acre) for seed and herbicide; The goal is to get the best results from the potential of the genetics, says Licht. An even bigger concern is that in 68 percent of the fields, the seed was planted too deep, a condition known to delay emergence. Proper management practices are important if you want to keep soybean profitable. The SMaRT project was developed to help Michigan producers increase soybean yields and farm profitability. But gaps of a foot or more between plants mean you need to adjust your planter settings. Alterations in plant spacing through row spacing and plant populations have a significant effect on canopy development and yield components. })(); Join our gardening family to receive the latest tips.

According to Purdue Extension, 67% of Indiana growers plant soybeans one to three weeks earlier than they did 10 years ago. (Click an image below to view a high-resolution image that can be downloaded). Decreasing the time to canopy closure can reduce soil moisture loss, increase the ability to control emerging weeds, and increase crop growth rate. Soybean seed is very sensitive to planting depth, so producers need to be careful and get their crop off to a good start. For more information, visit https://extension.msu.edu. 0000002402 00000 n What about the whole story on seeding rate versus economics?

Wet weather can delay wheat planting, but issues such as these can be overcome if you factor variety selection, rotations, seeding depth and rate into your planting decisions. Soybeans are not frost-tolerant. Dried, shelled soybeans can be stored in a cool, dry place for 10 to 12 months. At a given plant population, as row spacing decreases the plant spacing within the row increases and results in a more equidistant plant spacing. 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. 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. The apple and soybean roots were collected separately. 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.

Note that the recommended planting rates are for optimum yield, Kandel says. All rights reserved. It takes approximately 125 growing degree day units for soybean seedlings to begin to emerge from the soil, and it might be of use for people trying to time soybean planting to plant approximately 125 heat units earlier than the date of the last 32 degree frost. Table 3. Timely planting is critical for maximizing yield in soybeans, but using good judgement on field conditions plays a role that is equally important to determining yield potential. The minimum stand for maximizing soybean yields, and factors that affect this. Soybeans, however, can emerge reasonably well from a 2.5 inch depth, if soil crusting is not prevalent during actual emergence from the soil.
