Improved planter technology and increased seed quality have resulted in more accurate plant populations and stand establishment that are only slightly reduced from the seeding rate, and do not require over seeding by 20 to 30%. When planting with the standard closing wheels under wet soil conditions, however, using high down-force tended to bury the seed deeper, and didnt provide the small bit of tillage that the steel tine-type aftermarket closing wheels did which may have helped with emergence. Dried, shelled soybeans can be stored in a cool, dry place for 10 to 12 months. An important consideration when selecting the correct seeding rate is that seeds planted per acre will not be the same as plants per acre. You may want to apply a residual herbicide that will remain active in the soil for an extended period of time and act on successive weed germinations.

Soybeans have a similar growth habit to bush beans, so there's no caging or staking required. Soybean seed depth should be between to 1 inches. Plant seeds at a depth of 1-2 inches. 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. Futures: at least 10 minute delayed. In eastern North Dakota trials, 8% of planted PLS per acre did not develop into viable soybean plants. 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. Planting Date Decisions. Some are planting beans before corn, says Licht. Seed maturity, weather conditions and disease pressure influence whether a fungicide will pay for itself. Timely planting allows for soybean to maximize light interception and canopy photosynthesis, increase number of nodes and seeds per unit area, and lengthen the seed filling period. Across North Dakota and row spacings, the planting rate of about 170,00 PLS per acre optimized soybean seed yield, while optimum yield occurred with 180,000 and about 140,000 PLS per acre in eastern and western North Dakota, respectively.
