చెరకు: India’s most lucrative crop and the ethanol pivot
Sugarcane (Saccharum officinarum) is India’s most economically rewarding field crop per acre — and the most water-intensive. Grown on roughly 5.0 million hectares with annual cane production of 440-460 million tonnes (DES 2024-25 advance estimate), India is the world’s largest cane producer and second-largest sugar producer behind Brazil. The 2025-26 Fair & Remunerative Price (FRP), notified by Cabinet in February 2025, is ₹355 per quintal of cane at 10.25% basic recovery, with linear adjustment of ₹3.46/q per 0.1% above 9.5%. Unlike the MSP for cereals (declared but variably procured), the FRP is a statutory floor: sugar mills are legally bound to pay FRP within 14 days of cane delivery under the Sugarcane (Control) Order 1966.
Sugarcane is the only crop where India runs a centrally-administered statutory price mechanism that mills must honour, plus state-level SAP (State Advised Price) in UP, Punjab and Haryana that adds ₹15-30/q on top of FRP. Maharashtra and Karnataka do not declare SAP but mill cooperatives often pay a Revenue Sharing component above FRP. The 2024-25 UP SAP was set at ₹370/q for general variety and ₹380/q for early/premium variety — meaning the actual cane-grower payout in UP exceeds FRP by 5-10%.
Where sugarcane is grown — UP, Maharashtra and the deltas
Uttar Pradesh (48% of national production): the western and Terai belt — Muzaffarnagar, Saharanpur, Bijnor, Meerut, Gorakhpur, Bahraich, Lakhimpur Kheri. Predominantly alluvial soil with assured canal + tubewell irrigation. Average yield 800-850 q/ha (~80-85 t/ha); best farms in Muzaffarnagar push 1,100 q/ha. UP has 119 operational sugar mills (60% co-operative, 40% private) processing 6-7 lakh tonnes of cane daily during the crushing season (October-April). UP SAP is set politically every year before crushing begins.
Maharashtra (22%): the western Maharashtra and Marathwada cooperative belt — Pune, Ahmednagar, Sangli, Satara, Solapur, Kolhapur, Latur. Higher yield potential on black soils with drip-irrigation — 900-1,100 q/ha is routine. The state’s 193 sugar mills (largest in India by count) are 65% co-operative; the Pawar (Vasantdada Sugar Institute) cooperative ecosystem is the country’s benchmark. Maharashtra crushing season is October-March; the 2024-25 season was cut short to February in Solapur-Sangli because of monsoon deficit.
Karnataka (10%): Belagavi, Mandya, Mysuru, Bagalkot. Yield 750-900 q/ha on canal-irrigated red and black soils. The state has 67 sugar mills concentrated in north Karnataka. Bihar (4%): Bettiah, Motihari Champaran belt; 600-700 q/ha on alluvial soil. Tamil Nadu (4%): Erode, Salem, Coimbatore; 900-1,000 q/ha on borewell irrigation. Punjab and Haryana have small but high-yielding sugarcane areas (1,000-1,200 q/ha on Indo-Gangetic alluvium).
Variety landscape — Co-0238 ascendancy and the early/general split
India’s sugarcane variety landscape was transformed by Co-0238(released 2009 by ICAR-IISR Lucknow) — a Co-1148 × Co-9333 cross that combines high yield (90+ t/ha), high recovery (11.5-12%), early maturity (12 months) and tolerance to red rot. By 2018, Co-0238 covered 65% of UP cane area — the fastest variety adoption in Indian agricultural history. But the variety’s red-rot resistance has been breaking down since 2022 (climate-driven pathogen evolution), and the new replacement candidates — Co-15023, Co-118 (Karan-4), Co-15027, Co-15031 — are now being multiplied. For Maharashtra-Karnataka, the standard remains Co-86032(released 1997) at 950+ t/ha with 11% recovery. CoLk-94184 is the UP late-maturing premium variety; CoS-8436 is the UP eastern belt general.
The early-vs-general split is the most important commercial distinction. Early varieties (Co-0238, CoLk-94184) mature at 10-12 months — they are crushed in October-December when sucrose recovery is highest, earning the per-tonne FRP premium plus the early-cane payment (₹15/q in UP for cane crushed by 31 December). General varieties (Co-87263, CoSe-95436) crush January-March; they pay full FRP but no premium. A UP farmer with all-early planting has 8-12% higher gross revenue than a general-only farmer on the same land.
Planting, ratooning and the 3-year cycle
Sugarcane is unique among Indian field crops in being a long-duration semi-perennial. Planted (plant) crop: setts (3-bud cuttings) planted October-November (autumn) or February-March (spring) in furrows 90-120 cm apart at 6,000-8,000 kg setts per hectare. The plant crop matures in 12-14 months — harvested October-March of the following calendar year. Ratoon crop: after harvest, regrowth from the cane stubble is the ratoon, harvested 11-12 months later. UP typically takes 2 ratoons (3-year cycle: plant + ratoon-1 + ratoon-2); Maharashtra 1 ratoon (2-year cycle); Tamil Nadu sometimes up to 3 ratoons. Ratoon yield is typically 80% of plant crop yield in the first ratoon, declining further with successive ratoons.
Sett treatment is critical: hot water at 52°C for 30 minutescontrols grassy-shoot disease, ratoon-stunting disease and certain bacterial infections — a non-negotiable step in any high-yield cane operation. Carbendazim 0.1% dip controls red-rot at sett stage.
Nutrient management — heaviest feeder among Indian field crops
Sugarcane is the heaviest nutrient-removing crop in Indian agriculture. ICAR-IISR Lucknow’s recommendation for irrigated 80-tonne yield: 275:62.5:112.5 kg/ha N:P2O5:K2O plus 50 kg ZnSO4 and 25 kg FeSO4. Nitrogen split: 25% basal, 25% at 60 DAP (sprouting), 30% at 90 DAP (tillering), 20% at 120 DAP (grand growth). The 90-120 day window is the most yield-leveraged N application timing. Top-dressed urea at earthing-up. FYM at 10-15 t/ha plus Trichoderma harzianum 5 kg/ha as basal soil-amendment is the modern cane-farmer standard, especially in Maharashtra cooperative ecosystem.
Water management — the 2,500 mm crop
Sugarcane demands 2,000-2,500 mm of water per crop cycle — twice paddy and 5x cotton. FAO-56 Kc curve: Kc-ini 0.40, Kc-mid 1.25, Kc-end 0.75. The crop water demand peaks June-August (grand growth phase) at 8-10 mm/day. UP-Muzaffarnagar irrigated cane gets 15-20 irrigations per cycle; Maharashtra drip-fertigated cane needs 18-22 mm/day at peak but distributed continuously through emitters. The drip-fertigationpush under PMKSY-PDMC (55% subsidy for SMF) has transformed Maharashtra cane economics — drip cane yields 1,100-1,300 q/ha (15-25% higher than flood-irrigated) on roughly half the water. By 2024, drip coverage on Maharashtra cane reached 35%, the highest of any crop in any state. UP drip adoption remains under 5% because cooperative pricing structures do not differentially reward water-efficient cane.
Pest and disease management — the borer-rot trinity
Early shoot borer (Chilo infuscatellus): damages young shoots within 60 days of planting; characteristic dead-heart with offensive smell. ETL: 10% dead-hearts. Chlorantraniliprole 18.5SC at 375 ml/ha or fipronil 0.3G granular application at planting. Top borer (Scirpophaga excerptalis): characteristic “bunchy-top” symptom; rogue affected canes and use light traps. Pyrilla (Pyrilla perpusilla): a sucking pest causing honeydew + sooty mould. The most successful biocontrol intervention in Indian agriculture: releases of Epiricania melanoleuca (a host-specific parasitoid) in UP from the 1990s have kept pyrilla below ETL across most of the cane belt.
Red rot (Colletotrichum falcatum) is the most devastating disease — soil-borne fungus that turns cane internodes blood-red and rotten. The 2022-23 UP red-rot outbreak (affecting Co-0238 in eastern UP) caused an estimated 5% area loss. Management is varietal — Co-0238, Co-86032 and the new Co-15023 are tolerant. Hot-water sett treatment, three-row trench planting + 2.5 m fallow border between affected and healthy plots is essential. Smut (Sporisorium scitamineum): whip-shaped sori at the cane top; rogue + hot-water sett treatment. Grassy shoot disease (phytoplasma): thin, grass-like tillering; ratoon-stunting disease (RSD, Leifsonia xyli): internal yellow vascular discolouration. Both are sett-borne and need hot-water treatment.
Cost of cultivation, FRP and the mill-payment cycle
CACP places sugarcane A2+FL cost at ₹200/q on the national average; C2 cost at ₹255/q. Against FRP ₹355/q the C2 margin is 39% — among the highest for any crop. But cane economics is not just about FRP. The full revenue equation: Revenue = (Cane tonnage × recovery-adjusted FRP) + (state SAP top-up) + (early-cane premium) + (transport allowance). For a UP farmer with Co-0238 yielding 80 t/ha at 11% recovery, FRP-equivalent is ₹405/q (FRP ₹355 + 0.1% adjustment), plus UP SAP topup ₹25-30/q, plus early-cane premium ₹10-15/q — net realisation ₹440-450/q. Gross revenue: ₹3,52,000-3,60,000/ha. Cash cost: ₹1,40,000-1,55,000/ha. Net margin: ₹2,00,000-2,15,000/ha (₹80,000-85,000/acre) — the highest of any non-horticulture crop in India.
But this margin assumes timely mill payment. The 14-day statutory payment is routinely violated: UP mill arrears to farmers peaked at ₹15,800 crore in 2021-22 (later substantially cleared). Maharashtra arrears are smaller because of cooperative governance. Tamil Nadu mills have a chronic delayed-payment culture. The cash-margin calculation must therefore account for the ~6-month interest-free credit the farmer extends to the mill — the “hidden financing cost” of being a cane grower.
Ethanol pivot and the 20% blending target
The single most transformative policy for Indian sugarcane in the past decade has been the Ethanol Blending Programme (EBP). India achieved 12.5% ethanol blending in petrol by April 2024 and targets 20% (E20) by 2025-26. The implications for cane economics are large: sugar mills are increasingly diverting B-heavy molasses and even cane juice directly to ethanol (rather than sugar), earning ₹65-72 per litre from OMCs against the falling international sugar price. Total ethanol procurement by OMCs in 2023-24 was 660 crore litres; 2024-25 target 825 crore litres. The diversion policy needs careful management — too much cane to ethanol pushes domestic sugar prices up; too little means mills under-recover at the global sugar price. The Sugarcane (Control) Order has been amended to allow direct-cane-juice ethanol diversion since 2022.
Schemes — beyond FRP
PM-KISAN applies. PMFBY covers sugarcane optionally (not all states). KCC at 4% effective rate up to ₹3 lakh. Cane Development Programme (NFSM-Commercial Crops) subsidises tissue-culture healthy seed, hot-water treatment plant capex and drip irrigation. PMKSY-PDMC at 55% subsidy is the most-used scheme for Maharashtra drip cane. Ethanol Interest Subvention at 6% (DFPD scheme) supports mills setting up new ethanol plants — about 250 new distilleries operational by 2024-25 against 2018 baseline of 160.
The water question and the long horizon
Sugarcane sits at a contradiction. It is India’s most lucrative field crop and the country’s most water-intensive. UP’s sugarcane belt consumes roughly 22% of the state’s irrigation water on 8% of its cropped area. Maharashtra’s cane occupies 4% of cropped area but consumes 65-70% of dam irrigation — an inequity the state has tried to address through cane area capping (regulating new permit issuance) since 2018. The path forward is unambiguous: drip mandatory, surface flood phased out. Co-0238 successor varieties with red-rot resistance plus 10%+ recovery will be the next yield-driver. The ethanol diversion provides the economic ceiling for cane — but only at 20% blending; further blending (E27 by 2030) would require a 30% increase in cane area, which the water table cannot sustain. The economic ceiling and the ecological floor will meet somewhere around 2030.
