Amaranth (Amaranthus hypochondriacus / A. cruentus) — Rajgira / Ramdana / Chaulai — is India's most ancient pseudocereal and one of the world's most nutritionally extraordinary grains. Cultivated in the Americas by Aztec civilization for 8,000 years, amaranth was also independently developed in India where Amaranthus species have been part of the food system for millennia as both grain (Rajgira) and leafy vegetable (Chaulai). In modern India, Rajgira holds a special position: it is the primary fasting food (Navratri vrat food), a highly regarded health grain with extraordinary protein quality, a gluten-free alternative, and increasingly a specialty crop with growing export demand. India produces amaranth grain primarily in Uttar Pradesh, Himachal Pradesh, Uttarakhand, Rajasthan and Maharashtra's tribal belt. The nutritional distinction that sets amaranth apart from all other cereals and most pulses: amaranth contains squalene (a rare compound also found in shark liver oil and olive oil), lysine (the amino acid limiting in most cereals), and the highest protein quality of any grain — with a Protein Digestibility Corrected Amino Acid Score (PDCAAS) approaching meat and milk. For India's vegetarian population, Rajgira grain is arguably the single most nutritionally complete plant food available.
Amaranth (Amaranthus) — Rajgira / Ramdana — India का most ancient pseudocereal। Navratri vrat का primary food। Protein PDCAAS = meat/milk के approaching! Lysine highest cereal। Squalene unique compound (shark liver oil + olive oil में पाया जाता)। Gluten-free। 8,000 years Aztec civilization + India indigenous cultivation। Most complete plant food for vegetarians।
🌾 Overview, Classification & Varieties
| 🔬 Scientific Name | Amaranthus hypochondriacus (grain — Rajgira) | A. cruentus (grain) | A. tricolor (vegetable — Chaulai) |
| 📅 Season | Kharif (main) June-July | Rabi possible in South India | Short-day plant |
| 🌡️ Temperature | 20-35°C — warm season. Drought tolerant. Heat tolerant. Wide adaptability. |
| 💧 Water | 350-500mm — drought tolerant! C4 photosynthesis — efficient water use. Rain-fed possible. |
| ⏱️ Duration | Grain: 90-120 days | Vegetable leaf: 25-30 days | Multiple cuts possible for leafy type |
| 🌾 Yield | Grain: 1.0-2.5 t/ha | Leaf: 10-15 t/ha fresh | Small seed but high density panicle |

🪴 Soil, Sowing & Nutrient Management
🌿 Crop Protection & Management
| Tool / Resource | Use for Amaranth |
|---|---|
| 📅 Crop Sowing Calendar | Kharif amaranth dates + Navratri market timing planning |
| 🧪 Fertilizer Calculator | Low N + organic FYM dosage for premium grain quality |
| 🔍 Pest Identifier | Leaf spot vs leaf webber — identification for spray decision |
| 💧 Watering Calculator | Rain-fed schedule + supplemental irrigation at grain fill |
| 🌱 Germination Tracker | Tiny seed germination tracking — emergence uniformity |
🌾 Harvest, Nutrition, Uses & Economics
- Harvest at grain hardening — careful threshing: 90-120 days. Panicle (grain head) turns golden, seeds hard and begin to shatter. Cut panicles first (before all seeds drop). Dry 4-5 days. Thresh by beating on clean sheet — tiny seeds scatter easily. Winnow very carefully — seeds extremely light. Dry to 10-12% moisture. Sieve to clean. Storage: airtight containers — tiny seeds attack by weevil. Refrigerator storage for long-term: keeps 2-3 years. MSP: no formal MSP. Market price: Rs.60-100/kg commodity. Health food market: Rs.150-250/kg branded, certified organic. Popped Rajgira (laddoo grade): Rs.100-180/kg.
| Nutrition (per 100g grain) | Value | Note |
|---|---|---|
| 💪 Protein | 14-15g — highest pseudocereal | PDCAAS 0.75 — approaches meat/milk quality |
| 🌾 Lysine | 5.5% protein — highest grain | Limiting amino acid in wheat/rice — amaranth solves this |
| 🦴 Calcium | 159mg — 16% RDA | Highest calcium cereal — better than wheat or rice |
| ⚙️ Iron | 7.6mg — 42% RDA | Excellent iron + Vitamin C improves absorption |
| 🌿 Squalene | 6-8% of oil — unique | Found mainly in shark liver + olive oil. Anti-cancer, skin, cardiovascular |
| 🌾 Gluten-free | YES — 100% | Safe for celiac + wheat sensitivity. Complete nutrition without gluten. |
