Description:

Winter Barley cover crop grass is an upright, cool season annual grass known for its quick growth and low water use. Winter Barley grass is often used on soils where reclamation and/or rapid soil recovery is the goal.

  • Drought-tolerant; low water use
  • Ideal for suppressing weeds when planted at heavier seeding rates
  • Captures excessive nutrients left from cash crops
  • Silage value resembles whole-plant corn silage
  • Reduces some pests in fruit and vegetable crops
  • Known suppression to root knot nematode
  • Fall forage option (best use –fall pasture, silage and hay)
  • Best Use: Fall Pasture; Silage & Hay (boot to dough stage)

Considerations

    • Prefers pH 6.0 – 8.5
    • Inconsistent at overwintering versus other winter small grains
    • Avoid seeding in cold, damp soils
    • Winter barley is the most susceptible to winterkill of the cereal grains. Consideration should be made when grazing late into the fall. Barley’s value as a silage crop is the most comparable to whole-plant corn (90-100%).

Fertility
Fertilizer removal rates need to be considered as well. When utilizing cover crops as forage, it’s critical to consider the nutrients being removed along with the biomass. These fertilizer levels will need to be added to ensure maximum nutrient availability for the following cash crop.

Hay Production
Hay yields often average between 2-4 tons/acre. Moisture content should be between 15-20% moisture. Hay quality is more maturity-dependent at harvest than is silage.

The most efficient time to harvest small grain cereals for hay is at early-milk stage. This allows for the greatest compromise between forage yield and quality (quality would be greatest at the late-boot stage). To help speed up drying, a crimper is recommended when harvesting in the late-boot stage

Silage Production
Wheat, barley, oat and triticale silage yields are similar, 4-7 tons/acre of 35% dry matter forage in the boot stage and closer to 6-10 tons/acre when harvested in the late-boot stage. Small grains should be ensiled at between 62–68% moisture. Chop length should be set finer than when harvesting corn or forage sorghum.
