Management decisions at soybean planting are critical in setting the crop for success. 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. Regents of the University of Minnesota. Table 1. 0000022352 00000 n Check out the MSU Fruit & Vegetable Crop Management Program! Research indicates seed treatments aid in Phytophthora control and are highly economical. 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. 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. 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. Particularly with compaction (both surface and sidewall compaction) at planting time. Figure 3. With these conditions, emergence can typically be expected 2-3 weeks after planting. 0000110302 00000 n However, careful planning is required to minimize risks associated with early planting. Nevertheless, most producers have resisted lowering their planting rates accordingly. As processed meal or oil, soybeans make their way into human and animal foods, as well as an array of nonfood industrial products and fuel. We comply with the Federal Trade Commission 1998 Childrens Online Privacy Protection Act (COPPA). In dry seedbeds it may be tempting to plant deeper than 1.5 inches. 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.

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, low plant populations may result in lower pod height, lodging of lateral branches, and higher weed populations, all of which may result in harvest losses. After more than 30 experiments across the last 3 years we have seen very consistent data and even though we will finalize the studies in 2006 I have decided to share some of the data that we have found. Soybean plants are very flexible at adjusting to a wide range of plant populations. An even bigger concern is that in 68 percent of the fields, the seed was planted too deep, a condition known to delay emergence. })(); Join our gardening family to receive the latest tips. Across the U.S., narrow rows ( 15 inches) out-yielded wide rows ( 30 inches) 69% of the time. In most situations, 140,000 seeds per acre should result in at least 100,000 plants per acre at harvest. 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. One should, however, consider planting fullest-season soybean varieties earliest. Do not plant early if the soil is excessively cold or wet. Adjustable sowing space.You can adjust the plant spacing through the seed round or the chain gear.
