Turbo™

$2.00 /lb

Sudangrass is a warm season annual grass commonly used for hay and silage production, as well as grazing. Turbo is a very high yielding sudangrass hybrid that carries the brown midrib gene as well as a brachytic dwarf gene. Brachytic dwarf varieties are desirable because they will have the same amount of leaf area as taller varieties, but a shorter stalk which results in a higher leaf to stem ratio. The BMR gene lowers lignin levels in the plant, which results in more digestible fiber and much higher feed value in BMR varieties compared to non-BMR types. Turbo is extremely fast to establish and will have rapid regrowth in a multi-cut or grazing scenario. This makes it an excellent option as a season long crop, or for double forage cropping. Sudangrass is very drought tolerant and grows well under limited moisture conditions. It is used throughout the U.S. and can be productive in northern climates that have a short growing season. It will perform best on well drained soils and does not do well in flooding or standing water conditions. Sudangrass is somewhat tolerant to saline soils, but performance will be limited.

Drilled Seeding Rate: 15 lbs/acre

Product Guide

Planting

  • Planting Time: Late Spring – Mid Summer
    • Sudangrass needs a minimum soil temperature of 60 degrees to germinate
  • Drilled Seeding Rate: 15 lbs/acre
  • Ideal Seed Depth: ¾” – 1”

Fertility

Use the fertilizer rates below for maximum yield potential:

  Recommended Application Rate (Lbs/acre)
Soil Fertility Level Nitrogen (N) Phosphorus (P2O5) Potassium (K2O)
High 65 10 40
Medium 85 25 75
Low 100                          40 120

*Rates are recommended if no soil test is taken.

  • Apply ½ rate of nitrogen before or immediately after planting, and the other ½ rate 30 days after emergence.
  • If crop is intended for multiple cuttings, split apply the total rates recommended between each cutting.
  • Do not exceed a total of 10 lbs/a of N+K if fertilizer is placed in-furrow at planting.

Weed Control

Plant into a clean, weed-free seed bed and use the herbicide options below for optimal weed control:

Timing Herbicide Rate Notes Weeds Controlled Control Method
Preplant or Preemergence Makaze (Glyphosate) 32 oz/a Apply any time before crop emergence Grasses & Broadleaves Contact
Post-emergence Broclean (Bromoxynil) 1-1.5 pts/a Apply from 4-leaf stage and prior to preboot stage Broadleaves Contact

*Always read and follow label instructions before making an application

Harvest Management

  • Hay or Haylage: For best performance in a multi-cut system, cut either 40 days after emergence or when the plant is 40” tall – whichever comes first. Leave 4-6” of stubble to allow the best regrowth.
    • Cutting stimulates Turbo to tiller which causes the stand to thicken after each harvest.
  • In a single cut system, allowing plants to mature to at least the early heading stages will increase yield. Turbo maintains forage quality very well as it matures.
  • Grazing: Begin when plants are at least 18” tall and graze to a minimum stubble height of 4-6” before removing livestock to allow for regrowth.
    • Turbo performs best in a rotational grazing system due to its rapid regrowth.
  • Nitrates: Sudangrass that is stressed to the point of stunted growth can accumulate nitrates in the lower portion of the plant and should not be grazed or hayed during these stress periods. Ensiling sudangrass with high levels of nitrates will reduce them to safe levels.
  • Prussic Acid: Avoid sudangrass for 5-7 days following a killing frost due to the potential for prussic acid concentrations to reach toxic levels. After this period, it is safe to graze for the remainder of the season. If haying, the drying process will allow prussic acid to exit the plant and hay will be safe to feed. Ensiling also eliminates prussic acid concerns in sudangrass.
