Khorasan Green Hull

Triticum turgidum subsp. turanicum

grass

Khorasan, also known as Kamut, is an ancient hulled wheat variety with large, golden kernels and a nutty flavor. It is a tetraploid wheat (with 28 chromosomes) that is higher in protein and certain nutrients compared to modern bread wheat. This heritage grain is typically grown as a cool-season annual crop.

Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout and develop first leaves. Young shoots emerge from soil.

Sow in fall (September-October in most zones) or early spring for best results. Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing if direct seeded.

2

Vegetative Growth

4-6 weeks

Plant develops multiple tillers (shoots) and an extensive root system. Foliage is deep green and upright.

Apply nitrogen fertilizer as needed if soil is poor. Monitor for weeds and thin competing growth. Ensure adequate moisture. Watch for potential disease issues in humid conditions.

3

Jointing & Stem Elongation

3-4 weeks

Stems elongate and become more rigid. Plant height increases rapidly. Nodes (joints) become visible on stems.

Provide adequate water, especially if rainfall is limited. Reduce nitrogen fertilizer to prevent lodging. Monitor for pest activity. Stake or support if plants appear weak.

4

Flowering & Pollination

2-3 weeks

Seed heads emerge from the flag leaf. Flowers are small but visible in the head; self-pollination occurs. Heads elongate and mature.

Maintain consistent moisture during this critical stage for grain development. Avoid excessive nitrogen. Protect from strong winds if possible to prevent lodging.

5

Grain Fill & Ripening

3-4 weeks

Kernels develop and fill with starch and protein. Heads become heavier and may droop slightly. Color transitions from green to golden-tan as plant dries.

Continue moderate watering until plants begin to dry naturally. Do not fertilize at this stage. Monitor moisture content of grain—aim for 12-14% for harvest. Protect from birds if needed.

Common Pests

  • Sow at recommended times to avoid peak fly activity; use resistant varieties if available; remove crop residue promptly.

  • Monitor plants; use beneficial insects or insecticidal sprays if population thresholds are exceeded; maintain crop rotation.

  • No direct control; rely on resistant varieties and crop rotation; remove volunteer plants.

  • Avoid planting after corn or other susceptible crops; ensure good air circulation; use fungicide if needed during flowering; select tolerant varieties.

  • Improve air circulation; reduce nitrogen excess; apply sulfur or fungicide if severe; choose resistant varieties.

Uses

🍳

Ancient Grain Flour & Whole Grain

Culinary

Khorasan flour is prized for its nutty, slightly sweet flavor and can be used in bread baking, pasta, and whole grain dishes. It is increasingly popular with artisanal bakers and health-conscious consumers. [source]

🍳

High Protein Content

Culinary

Khorasan wheat contains approximately 14-18% protein, making it higher in protein than modern commercial wheat varieties. This makes it valuable for protein-rich grain bowls, pasta, and baked goods. [source]

🏠

Sustainable & Organic Farming

Household

As a heritage grain, Khorasan is widely grown in organic and sustainable farming systems. It is often marketed under the Kamut brand name, which emphasizes organic certification and heritage seed preservation. [source]

💊

Mineral & Nutrient Density

Medicinal

Khorasan is rich in selenium, magnesium, phosphorus, and other minerals, and contains higher levels of lipids (healthy fats) compared to common wheat. Some traditional systems value it for nutritional support. [source]

🦋

Bird & Pollinator Food

Wildlife

Unharvested or volunteer Khorasan plants provide seeds and forage for wild birds and beneficial insects. The open seed heads and tall stems support diverse insect populations during the growing season. [source]

Harvest Tips

Harvest when plants are completely dry and grain moisture is 12-14%. Heads should be tan-golden and kernels should not dent easily when pressed. Cut or thresh heads by hand for small plots, or use a combine harvester for larger areas. Dry grain thoroughly (to 10-12% moisture) before storage to prevent mold.

Fun Facts

  • 🌱 Khorasan is one of the world's oldest cultivated wheats, with origins in the Khorasan region of Iran (now northeastern Iran and adjacent areas). It was nearly lost to extinction but was re-introduced commercially in North America in the 1980s under the trademarked name 'Kamut.'
  • 🌱 Khorasan kernels are significantly larger than modern bread wheat—approximately 30-40% larger—which makes them visually distinctive and easier to separate from chaff during processing.
  • 🌱 Some people with gluten sensitivity report better tolerance to Khorasan wheat compared to modern bread wheat, though it does contain gluten. This may be due to its different gluten structure and higher nutrient density, though scientific evidence is still emerging.
