Growth Stages

1

Seedling

2-3 weeks

Emergence of first leaves; plant is 2-4 inches tall with thin, upright growth

Ensure consistent soil moisture for germination. Monitor for seedling pests and diseases. Thin to proper spacing if needed.

2

Vegetative

3-4 weeks

Plant develops 4-8 leaves, stem thickens, height reaches 12-24 inches. Strong root system establishes.

Apply pre-emergent herbicides for weed control. Begin monitoring for pests. Fertilize if soil tests indicate deficiency.

3

Boot to Heading

2-3 weeks

Panicle emerges from boot leaf; plant height 24-48 inches. Flowering begins as panicle extends.

Critical irrigation period if rainfall is insufficient. Scout for aphids and mites. Avoid herbicide applications during this stage.

4

Flowering to Soft Dough

3-4 weeks

Panicle in full bloom; kernels develop and reach soft dough stage. Plant reaches full height (36-60 inches).

Monitor for head mold and grain mold diseases in humid conditions. Continue pest monitoring. Reduce irrigation as grain matures.

5

Physiological Maturity to Harvest

2-3 weeks

Kernels harden; black layer forms at base of kernel. Plant dries down; leaves senesce.

For forage, harvest at boot to early heading stage for highest digestibility. For grain, wait for hard dough stage (moisture 15-20%). Allow stalks to cure if standing for harvest.

Companion Planting

Plan your garden →

Plant with:

Legumes (alfalfa in mixed forage stands) Cowpeas (in intercropping systems) Velvet beans

Avoid planting near:

Corn (competes for resources; disease overlap) Sudangrass in early rotation (allelopathic effects)

Common Pests

  • Plant resistant varieties; monitor panicles during bloom; insecticide applications if threshold (1-2 midges per panicle) is reached

  • Scout regularly; use Bt products for organic control; broad-spectrum insecticides for severe infestations

  • Resistant varieties; early plowing of crop residue; targeted insecticides at whorl stage if economic threshold exceeded

  • Resistant varieties; insecticide spray if colonies cause leaf yellowing and stunting

  • Plant disease-resistant varieties; avoid excess irrigation during flowering; ensure adequate air circulation; fungicide applications if needed

Uses

🍳

Livestock Feed & Forage

Culinary

DEKALB Forage sorghum is widely used as nutritious silage, hay, or grazing forage for cattle, sheep, goats, and other livestock. It provides high-quality feed with good energy content and digestibility, especially when harvested at the boot stage. [source]

🍳

Grain for Animal Feed

Culinary

The mature grain can be harvested and used as a concentrate feed ingredient for livestock, poultry, and swine. It serves as an alternative to corn and is often used in feed milling operations. [source]

🦋

Wildlife Food & Habitat

Wildlife

Standing sorghum provides food and cover for numerous bird species and small mammals. The seed head is a valuable food source for quail, pheasants, and songbirds. [source]

🏠

Biofuel & Biomass

Household

Sorghum biomass can be converted to ethanol, biogas, or other renewable energy products. Its high cellulose content and drought tolerance make it attractive for sustainable fuel production. [source]

💊

Drought-Resistant Crop & Climate Resilience

Medicinal

DEKALB Forage is highly valued in water-limited regions and provides food security for livestock operations in semi-arid climates. Its drought tolerance helps farmers maintain productivity during dry years. [source]

Harvest Tips

For forage/silage: Harvest at boot to early heading stage (50-60% moisture) for optimal digestibility and yield. Use forage chopper or baler. For grain: Harvest when kernels reach hard dough stage (15-20% moisture content). Use combine harvester. Allow 1-2 weeks of drying if moisture exceeds 20%. Stover can be baled for additional forage value.

Fun Facts

  • 🌱 Sorghum is one of the oldest cultivated crops, with origins in Africa dating back over 5,000 years. It is the fifth-most important cereal crop globally by production volume.
  • 🌱 DEKALB varieties are bred using advanced genetics and selection techniques to optimize forage quality, disease resistance, and drought tolerance for modern agricultural systems.
  • 🌱 Sorghum produces allelopathic compounds that can inhibit the growth of competing plants, making it a useful tool for weed management in sustainable and organic farming systems.
