Seedling
2-3 weeksShoots emerge with fine, grass-like leaves; plant is 4-6 inches tall
Keep soil evenly moist; thin seedlings to proper spacing; protect from birds
Vegetative
4-6 weeksRapid leaf growth; plant develops multiple tillers; reaches 2-3 feet tall
Water regularly during this phase; apply nitrogen fertilizer mid-stage; control weeds
Boot and Heading
3-4 weeksSeed head emerges from flag leaf sheath; plant reaches full height of 4-5 feet
Reduce watering; monitor for diseases; support tall plants in windy areas
Flowering and Grain Fill
3-4 weeksSeed head opens and flowers; distinctive black-hulled grain develops and hardens
Minimal water needed; watch for pest damage; allow air circulation to prevent mold
Maturity and Harvest
2-3 weeksKernel is hard and difficult to dent with thumbnail; seed head browns and hardens; moisture drops to 12-15%
Stop all irrigation; allow full dry-down; harvest when stalks are completely brown and brittle

Harvest Tips
Harvest when seed heads are fully mature and brown, typically 110-130 days after planting. Cut or bend seed heads into a collection tray when stalks are completely brittle and dry. Allow harvested heads to dry further in sun for 1-2 weeks before threshing. Thresh by hand (beating against bucket) for small plots or use mechanical thresher for larger quantities. Store in cool, dry location; clean seeds to remove chaff.
Fun Facts
- 🌱 Black Hull Kafir is one of the oldest cultivated grain sorghums, with origins in Ethiopia and the Sudan, and has been used for thousands of years in African and Middle Eastern cuisines.
- 🌱 Sorghum plants produce compounds called dhurrin that can inhibit weed growth and pest feeding, making them naturally allelopathic and reducing the need for chemical inputs.
- 🌱 A single Black Hull Kafir plant can produce 1,000+ grains and withstand severe drought by shutting down growth and resuming when water becomes available—a survival strategy unmatched by most grain crops.
