Ideally target planting at a depth of 1"-1.25" in optimal soil moisture conditions. A low plant population can be competitive with higher plant populations as long as the plant population is uniformly distributed in the field. Plant soybeans in full sun; soybeans will tolerate partial shade but the yield will be reduced. Soybeans for shelling and fresh use are ready for harvest 45 to 65 days after sowing. While shorter season varieties will not gain yield potential with an earlier planting date, a longer-season variety will, adding another couple of nodes of pods when planted earlier compared to later. listeners: [], USDA shows 8% of the nation's corn crop and 4% of the U.S. soybean crop is now planted.

Seeding rate and number of viable plants are influenced by many factors. Since there is good evidence that soybean is already source limited, any more reduction on source capacity would come at a cost of yield per plant. Slower germination and compaction can negate the benefits of the earlier planting date. Active down-force systems maintain gauge wheel load and maintain a steady load across the field by lifting and alleviating some pressure or providing down-pressure. Be sure your conditions are such that reduced row width and greater seeding rates justify the increased cost of seed. Optimal planting date, seeding rate and row spacing are important to maximize soybean yield and profits.
