రాగి (వేలు మిల్లెట్): Karnataka's nutri-cereal flagship
Ragi or finger millet (Eleusine coracana) covers about 1.1 million hectares producing 2.0 million tonnes nationally (DES 2024-25), with Karnataka alone accounting for 58% — the largest concentration of any millet in any state. Per gram of grain, ragi delivers 344 mg calcium (3x cow's milk by dry weight), 3.9 mg iron and 7.3 g protein — a nutritional density that has driven the Karnataka government to make ragi mudde and ragi malt central to its Anganwadi and PM-POSHAN supply chain. The 2025-26 MSP is₹4,886/q — the highest among cereals — reflecting CACP's effort to close the cultivation-cost gap and counter ragi's slow real-income decline against paddy and maize.
Geographic concentration
Karnataka (58%): Tumakuru, Mandya, Hassan, Bengaluru Rural, Chikballapur, Kolar — the "ragi belt". Bulk transplanted on red sandy loam, rainfed with occasional life-saving irrigation from open wells. Yields 14–22 q/ha. Karnataka's Raitha Siri pays ₹10,000/ha bonus to farmers shifting from paddy to ragi, supported by KMF's ragi malt baby food brand launch (2024) creating ₹40+/kg farmgate premium for APMC ragi.
Tamil Nadu (10%): Salem, Dharmapuri, Krishnagiri — rainfed plateau cultivation. ML-365 (Indaf-9) dominant. Yields 12–18 q/ha.
Uttarakhand (8%): Garhwal-Kumaon hill belt — known locally asmandua. VL-Mandua-352 (Vivekananda Parvatiya Krishi Anusandhan Sansthan, Almora) is the standard. Yields 14–18 q/ha rainfed.
Maharashtra (7%): Konkan and Vidarbha tribal pockets. Local landraces; consumption-led production with limited mandi marketing.
Andhra Pradesh (5%): Anantapur dryland; ICRISAT-bred lines under scaling.
Varieties — GPU series and the Karnataka breeding pipeline
GPU-28 (UAS Bengaluru, 2002) is the workhorse Karnataka variety — 28 q/ha potential, 115-day duration, blast-resistant, finger-shaped earhead. GPU-66 is the higher-yielding successor (30 q/ha, 110 days). ML-365 (Indaf-9, 1985) remains popular in TN-Salem for its drought tolerance. VL-Mandua-352 is the standard for Uttarakhand hills with its 105-day cycle that fits the short Himalayan growing season. Iron-biofortified VR-1054 and KMR-204 are released but yet to scale commercially.
Sowing, transplanting and water
Karnataka transplanted ragi: nursery sown June 15-25 (5-8 g seed per square metre), transplant at 25-30 day seedlings July 20 to August 10 at 30 × 10 cm spacing. Direct seeded ragi (rainfed plateau): sow May 25 to June 25 at seed rate 10 kg/ha. Nutrient requirement: 50:40:25 NPK kg/ha — modest. Most Karnataka ragi farms apply only N (20 kg/ha as urea) plus FYM 5 t/ha. The FAO-56 Kc curve (0.30 / 1.00 / 0.30) gives a seasonal ETc of ~360 mm for a 115-day crop. Rainfed crop relies on monsoon distribution June-October. Critical water windows are tillering (35 DAT) and panicle initiation (60 DAT) — life-saving irrigation here adds 4-6 q/ha.
Pests and the blast problem
Finger millet blast (Pyricularia grisea) is the dominant disease — leaf blast in early growth, neck blast at heading. Heavy infection on susceptible varieties can cut yield 40-60%. Modern GPU-28, GPU-66 and ML-365 carry partial resistance. Spraying tricyclazole 75WP at 0.6 g/L at boot stage protects when high-humidity weather threatens. Helminthosporium leaf spot is secondary; managed with mancozeb 2.5 g/L. Pink stem borer and armyworm can attack but rarely cross ETL.
Cost of cultivation and the Karnataka mandi premium
Ragi C2 cost (CACP 2022-23) averages ~₹3,400/q nationally and ~₹3,200/q in Karnataka. Against the ₹4,886/q MSP, the C2 margin is 44%. But the Karnataka mandi reality is higher than MSP — premium GI-tagged Kollegal and Mandya ragi trades at ₹5,500–6,500/q in retail-facing channels (KMF, Soulfull, Slurrp Farm), with farmer realisation at ₹5,000–5,300/q for grade-A bold-grain lots. Karnataka NAFED procurement under PSS crossed 4 LMT in 2024-25 — the largest single-state millet procurement on record.
A Tumakuru smallholder farming 1 ha of transplanted ragi yielding 20 q at ₹5,000/q mandi: gross ₹1,00,000, cash cost ~₹22,000, net cash margin ₹78,000/ha (~₹31,000/acre). On top, Raitha Siri ₹10,000/ha bonus and the per-acre PM-KISAN ₹3,000 (for ~1 ha holder) make the effective margin closer to ₹91,000/ha — competitive with sugarcane on the same land but at a third of the water footprint.
Schemes — Raitha Siri and the Odisha Millet Mission
Karnataka's Raitha Siri (since 2018) pays ₹10,000/ha bonus to farmers growing minor millets including ragi — disbursed via DBT. The bonus is the single biggest reason Karnataka ragi area has held steady at ~7 lakh ha against the all-India millet decline. Odisha Millet Mission has revived ragi-jowar mixed systems across 14 districts with FPO-led procurement at ₹5,000/q. PM-POSHAN adds ragi to school mid-day meals; KMF supplies ragi malt to Karnataka Anganwadi network. PM-KISAN, PMFBY and KCC apply standardly.
Climate, nutrition and the urban demand pull
Ragi's water footprint (~360 mm) is the lowest among cereals after pearl millet, and its calcium-iron-fibre nutrient density is the highest among cereals. NICRA projects ragi adaptability stretching further north as warming accelerates — Maharashtra-Vidarbha and southern MP could absorb 0.3-0.5 million hectares of additional ragi area by 2035 if urban demand sustains. The KMF ragi malt launch and the millet retail wave (Tata Sampann ragi atta at ₹120/kg, Aashirvaad multi-millet at ₹160/kg) have created a structural demand pull. For Karnataka smallholders on shallow red soils, ragi is now the highest-margin food crop available — a quiet revolution in the dryland.
