Editorial Summary: Down to Earth argues that India’s ethanol blending push has rapidly made maize the dominant feedstock, with around 9 lakh hectares of additional area in the 2025-26 kharif season displacing pulses and oilseeds and turning India into a net maize importer for the first time in decades. Policymakers must recalibrate the policy to embed safeguards for food security, nutrition, water, and soil within the energy transition framework — including yield-focused R&D, water-saving cultivars, and crop-diversification incentives.
The Policy Trajectory — E20 in 2025-26, E30 in May 2026
India’s biofuel framework was set out in the National Biofuel Policy 2018 and accelerated by an amendment in June 2022 that advanced the E20 target from 2030 to 2025-26. The E30 standard was notified in May 2026.
| Milestone | Year |
|---|---|
| National Biofuel Policy | 2018 |
| Amendment advancing E20 target | June 2022 |
| E20 achieved nationally | 2025 |
| E30 standard notified | May 2026 |
The policy categorises ethanol by feedstock generation:
- 1G ethanol — from sugar molasses (B-heavy, C-heavy) and grains (broken rice, maize, Damaged Food Grains)
- 2G ethanol — from lignocellulosic biomass (rice straw, bagasse, agricultural residues)
- 3G ethanol — from algae and other advanced biomass
The 1G pathway scaled fast. The 2G and 3G pathways have not.
Why Maize Became Dominant
Sugarcane molasses, the original 1G feedstock, has approached its diversion ceiling — roughly 60% of molasses is already converted to ethanol, with the balance needed for chemicals, beverages and animal feed. Grain-based ethanol from broken rice, Damaged Food Grains and FCI rice surpluses filled part of the gap, but the FCI rice route was later restricted on food-security grounds.
That left maize as the scalable kharif feedstock.
| Feedstock Property | Value |
|---|---|
| Ethanol yield from maize | ~480-490 L per tonne of grain |
| Crop season | Kharif (rainfed and irrigated zones) |
| 2025-26 ethanol procurement price — B-heavy molasses | ~₹60.73/L |
| 2025-26 ethanol procurement price — C-heavy molasses | ~₹56.58/L |
| 2025-26 ethanol procurement price — FCI/maize-based | ~₹71.86/L |
The procurement price structure tilted economics decisively toward maize.
The 2025-26 Acreage Shift
The 2025-26 kharif season saw approximately 9 lakh hectares of additional maize area in India, displacing pulses and oilseeds.
What Was Displaced
| Crop Category | Crops Affected |
|---|---|
| Pulses | Tur (arhar), moong, urad |
| Oilseeds | Soybean, mustard, groundnut |
Where the Shift Was Biggest
- Madhya Pradesh — soybean and pulses to maize
- Karnataka — pulses to maize in northern districts
- Telangana — soybean to maize
- Andhra Pradesh — pulses to maize
- Maharashtra — soybean to maize in Vidarbha and Marathwada
India’s maize production for FY26 is estimated in the 38-40 million tonne range — and yet the country has slipped into the net-importer column.
India Becomes a Net Maize Importer
For decades, India was a net exporter of maize. In 2024-25, India turned into a net importer of maize for the first time in that period.
| Indicator | Value |
|---|---|
| Earlier status | Net maize exporter for decades |
| 2024-25 status | Net importer for the first time in decades |
| Import sources | United States, Ukraine, Myanmar |
The imports have ripple effects beyond India — they disrupt global commodity markets and complicate trade relations, particularly with US corn exporters lobbying for permanent market access.
Food and Nutrition Implications
The maize-ethanol pivot has displaced two crop families that India is structurally short on.
Pulses
- India imports around 4.6 million tonnes of pulses (FY24, a six-year high), rising to a record 6.5-7.3 million tonnes in MY 2024-25 — the largest pulses importer in the world
- Pulses are the principal source of plant protein for Indian diets; displacement worsens nutrition outcomes
- The National Pulses Mission targets 35 million tonnes by 2030-31 — incompatible with continued area loss to maize
Edible Oils
- India imports around 60% of its edible oil consumption — an annual import bill of around $15 billion
- The National Mission on Edible Oils — Oilseeds (NMEO-Oilseeds, 2024-25 to 2030-31) targets oilseed area expansion
- Soybean and mustard, principal kharif and rabi oilseeds, are exactly what maize is displacing
Poultry Feed and Food Inflation
Maize is the principal input in poultry feed. Rising maize prices feed directly into chicken and egg prices, which disproportionately affect lower-income consumers for whom poultry is a primary affordable animal-protein source.
Environmental Costs
Water
1G ethanol production uses approximately 1,500-2,000 litres of water per litre of ethanol. The maize-irrigated regions of India are among the more water-stressed in the country.
Soil
Maize monoculture displaces nitrogen-fixing pulse rotation. The agronomic consequence is faster nitrogen depletion, micronutrient loss, and yield plateauing — exactly the dynamic that the long-term diversification logic of Indian agronomy is designed to prevent.
Tailpipe Emissions
Ethanol-blended fuels can elevate acetaldehyde and formaldehyde emissions at the tailpipe — a gap not yet adequately captured in current BS-VI norms. This is a separable concern, addressed in detail in the May 20 daily edition; the policy point is that auto-emission standards need to evolve in parallel with blending levels.
The Economic Case — Real but Partial
The ethanol blending programme has delivered genuine benefits.
| Benefit | Estimate |
|---|---|
| Cumulative forex saving 2014-2024 (Petroleum Ministry) | ~₹99,000 crore (~US$11.8 billion) |
| Farmer income for maize farmers | Remunerative procurement prices |
| Use of surplus and broken grain | Productive monetisation |
| Petrol decarbonisation | Partial, ongoing |
| Particulate emissions in transport | Reduced |
The case for blending was sound. The case for letting maize crowd out pulses and oilseeds without a parallel investment in yield, water and crop diversification is not.
Policy Contradictions
The maize-ethanol pivot contradicts other stated policy objectives.
| Programme | Stated Target | Conflict |
|---|---|---|
| National Pulses Mission | 35 mt by 2030-31 | Pulse area is shrinking as maize expands |
| NMEO-Oilseeds (2024-25 to 2030-31) | Oilseed self-sufficiency expansion | Soybean and mustard displaced by maize |
| Water conservation programmes | Reduce irrigation intensity | 1G ethanol is water-intensive |
| Edible Oil import substitution | Reduce $15 bn import bill | Reverse trend in 2025-26 |
Policy coherence requires that the ethanol programme operate within food-security and water-security envelopes, not as a parallel track that overrides them.
Way Forward
Down to Earth’s recommended course correction:
- Cap maize-ethanol diversion at around 30% — proposed by Economic Survey 2025-26 — with automatic feedstock review triggered when domestic maize imports cross a defined threshold
- R&D for higher-yield maize cultivars — move from the current national average of around 3 tonnes a hectare toward the achievable 7-8 tonnes a hectare through public-sector and ICAR-led breeding programmes
- Water-saving cultivation — drip irrigation, precision fertiliser application, and shift to less-water-intensive maize varieties in stressed regions
- Re-incentivise pulses — a 10%-of-MSP premium under an expanded PM-AASHA framework, alongside procurement guarantees
- Accelerate 2G ethanol commercialisation — through the HPCL Bathinda and IOCL Panipat lignocellulosic plants, supported by viability gap funding where required
- Compressed biogas via SATAT — Sustainable Alternative Towards Affordable Transportation, as an alternative to grain-based ethanol
- National Biofuel Coordination Committee — should publish a periodic food-energy-water review linking ethanol blending levels with crop area, water use and import dependence on pulses and oilseeds
- Bring NMEO-Oilseeds and the Pulses Mission targets into feedstock-planning calculus — so that ethanol policy is consistent with the food-security architecture

Editorial Insight
The maize-ethanol story is a useful reminder that energy transition policy does not happen in isolation from food, water and nutrition policy. India’s ethanol programme has delivered real benefits — about ₹99,000 crore in cumulative forex savings from 2014 to 2024, farmer income, partial decarbonisation — but it has also displaced pulses and oilseeds, raised poultry-feed prices, intensified water use, and pulled the country into the net-importer column for maize for the first time in decades. The right policy response is not to halt blending; it is to install guardrails. A diversion cap, a yield-focused R&D push, a re-incentivised pulses regime, and faster 2G commercialisation can convert the maize lesson into a structural correction. The slogan should be food-first within an energy transition, not energy at the cost of food.
