Luckily for multicrop producers, corn-planting equipment also works for soybeans with very few adjustments. 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. Seeding rate. 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. 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. Row width and seeding rates Seeding rates vary with row spacing (Table 2.) 0000112606 00000 n If an insecticide/fungicide seed treatment is used, seeding rates can be reduced by 10,000 to 20,000 seeds per acre. Black-seeded beans are used for drying. 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. In determining when to put seeds in the ground, soil condition and weather trump date. In this case, most of the seed was planted too deep (see photo). Plant spacing should be thought of as existing in two directions: 1) within row spacing and 2) between row spacing. Green-seed cultivars are considered the most tender and best flavored. Although early planting is important to maximize yield, planting into a wet seedbed can result in compaction and soil crusting which could reduce stand establishment and yield. 0000008382 00000 n Higher plant populations result in canopy closure earlier in the season and greater light interception. Likewise, insecticide seed treatment may be desirable if the field is known for insect pests. He says in some cases, the adjustment to row spacing will impact weed control more than yield. 0000023066 00000 n Sow soybeans in spring 2 to 3 weeks after the average last frost date when the soil has warmed to at least 60F (16C). Corn emergence was again approximately 2% higher when using low down-force than high down-force. So here are some tips for planting soybeans: Strive for uniform depth of planting. SMaRT is a partnership between MSU Extension and the Michigan Soybean Checkoff program. Data contributed from Michigan was generated based on research funded by Michigan Soybean Committee. At a fixed row width, as plant population increases the plant spacing within the row decreases and interplant competition increases.
