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. In Michigan, most farmers plant soybean in 15- or 30-inch row widths. Table 1. Slower germination and compaction can negate the benefits of the earlier planting date. An important factor in determining soybean seeding depth is the process of germination and emergence. This work resulted in the NDSU Extension publication Soybean Response to Planting Rates and Row Spacings in North Dakota (A1961). Soybeans grow best where the daytime temperature averages between 60F and 70F (16-21C). Prior to 2006, our recommendations were conducted prior to the use of roundup ready varieties. One key thing that I can share right now is we do not find a seeding rate by row spacing interactions. Although every attempt is made to produce information that is complete, timely, and accurate, the pesticide user bears responsibility of consulting the pesticide label and adhering to those directions. How to avoid yield loss with late-planted soybeans. We connect with people in all stages of life, from young children to older adults.
