S&W Seed SS405

SS405 is a late maturing, tall silage hybrid with high tonnage yield performance. Due to a high sugar content, stalks are very sweet and juicy. It is adapted for all but the shorter, cooler growing seasons in the northern Great Plains and at higher elevations. In its northern area of use, it may not produce a head. Plant height reaches 10 to over 12 feet with very good standability. In some areas it is grown for bio-mass ethanol production.

Applications & Uses

Hybrid Forage Sorghum Management
  • Planting Date: Late March through early June. Soil temperature should be 60°F to 65°F or warmer. Planting too early can result in slow early growth and reduced plant population.
  • Planting Depth: 1" to 1½" deep depending on soil moisture.
  • Row Width: 15" to 40" rows.

Fertility

  • Nitrogen: 7 lbs/acre per ton of silage harvested.
  • Phosphorus: 3 pounds/acre per ton of silage harvested.
  • Potassium: 7 lbs/acre per ton of silage harvested.
  • Magnesium: 1.7 pounds/acre per ton of silage harvested.
  • Sulfur: 0.8 pounds/acre per ton of silage harveted. Actual P & K needs should be based on current soil test levels.
