Ragi (Finger Millet)
Eleusine coracana
📖 About this plant
Ragi (Eleusine coracana), known as ragi in Kannada/Hindi, kelvaragu in Tamil, mandua in Hindi, and finger millet in English (for the characteristic hand-like “finger” inflorescence), is a hardy annual grass in the Poaceae family — one of the most nutritious of all cereals and a staple food for over 100 million people in the semi-arid tropics of Africa and south Asia. Native to East Africa (Uganda and Ethiopia), where it was domesticated over 5,000 years ago, finger millet arrived in India around 1,500 BC and became the staple grain of the dry regions of south India (Karnataka, Tamil Nadu, Andhra Pradesh) and the Himalayan foothills (Uttarakhand, Himachal Pradesh). Today, India is the worlds largest producer of finger millet (about 60% of global supply), with major cultivation in Karnataka (the largest producer — especially the southern districts of Mysore, Mandya, Hassan), Tamil Nadu, Andhra Pradesh, Telangana, Odisha, Maharashtra, and Uttarakhand. The plant is a small (50-120 cm) bushy grass with bright green folded leaves and a characteristic inflorescence of 5-7 finger-like spikes (called “curved fingers” — giving the grain its English name) that contain hundreds of tiny (1-1.5 mm) round reddish-brown seeds. The grain is exceptionally nutritious — among the richest cereals in calcium (344 mg/100g — over 10x more than rice or wheat!), iron, dietary fiber, plant protein, B vitamins, and antioxidants (especially the dark varieties, which contain tannins and anthocyanins). It is also gluten-free and has the lowest glycemic index of any cereal — making it ideal for diabetics. In south India, ragi is ground into flour and made into mudde (ragi mudde — the famous Karnataka ball of cooked ragi flour, eaten with sambar or chutney), dosa, idli, roti, and porridge (ragi koozh — the famous Tamil Nadu fermented summer drink made with buttermilk). Ragi is also given to babies as a weaning food (ragi porridge — considered one of the most nutritious first foods in Indian tradition) and to lactating mothers and the sick for strength. In Uttarakhand and Himachal, ragi (mandua) is made into rotis, halwa, and ladoos. In Ayurvedic medicine, ragi is considered cooling, warming in digestion, and nourishing — recommended for vata and pitta doshas, for diabetes (low glycemic), weight loss, anemia (high iron), osteoporosis (highest calcium of any cereal), and as a weaning and postpartum food.

💡 Care tips
- Direct sow seeds or transplant seedlings.
- For direct sowing: sow seeds 1-2 cm deep, broadcast or in rows 25-30 cm apart, at the start of the monsoon (June-July in India).
- Thin seedlings to 10-15 cm apart after establishment.
- For transplanting: sow seeds in a nursery, then transplant 25-30 day old seedlings to the main field — this gives better weed control and stand establishment.
- Plant in full sun in well-draining, even poor loam.
- Ragi thrives in poor soils where other cereals fail and tolerates a wide pH range (5.0-7.5) — including acidic soils.
- Water sparingly — ragi is drought-tolerant and suffers from overwatering.
- Water during germination and flowering if rainfall is inadequate
- otherwise rely on monsoon.
- Stop watering when heads turn brown and dry.
- Do NOT apply nitrogen — ragi is a low feeder.
- Apply phosphorus and potassium at planting if soil is poor.
- The plant grows rapidly — 50-80 cm in 50-70 days.
- Heads (fingers) mature 100-130 days after sowing.
- Harvest when heads turn from green to straw-brown and grains become hard — cut individual heads (not entire plants, as ragi tillers and heads mature over several weeks) over a 2-3 week harvest window.
- Dry heads in the sun for 3-5 days, then thresh to release grain (thresh by beating with sticks or by trampling).
- Winnow to remove chaff.
- Dry grain to 12% moisture before storage.
- Store in airtight containers — add dried neem leaves to prevent insect infestation.
- Save seeds for next year — they remain viable for 1-2 years.
- Popular Indian varieties include MR-1, MR-6, GPU-28, PR-202, CO-13, Indaf-9, and the high-yielding VL Mandua series.
- For cooking: ragi grains are too small to cook whole, so they are always ground into flour.
- Sprout ragi (soak for 8 hours, drain, sprout for 2-3 days) — sprouting enhances nutrient availability (especially iron and calcium) and reduces anti-nutrients (phytates).
- Dry sprouted ragi in the sun, then roast lightly and grind into flour (sprouted ragi flour is the most nutritious form, used for baby food and porridge).
- For home gardeners, ragi is one of the easiest and most rewarding millets to grow — fast, drought-tolerant, beautiful with its finger-like seed heads, and exceptionally nutritious.
