Beans will compensate for plant spacing and other ills. Planting into a poor seedbed, use of poor quality seed, inaccurate planter adjustment, planting too fast, soil crusting, soil moisture extremes, and environmentally induced plant injuries such as herbicide drift, pathogens, insects, hail, or frost all reduce plant population requiring a greater seeding rate. 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. Management decisions at soybean planting are critical in setting the crop for success. Soybeans are rarely attacked by a disease. 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. Seeding rate or planting rate refers to the number of soybean seeds planted per acre to attain a certain plant population. So here are some tips for planting soybeans: Strive for uniform depth of planting.
