Crops, irrigation & farm marketing

A technology mission bundles research, quality seed, inputs, extension and market support into a time-bound push on one crop or sector; the Technology Mission on Oilseeds (1986) set the template.

The missions

• Technology Mission on Oilseeds (1986), later extended to pulses, oil palm and maize: drove the Yellow Revolution and near self-sufficiency in edible oils by the 1990s.
• Technology Mission on Cotton (2000): better varieties, integrated pest management and modernised ginning raised yields and fibre quality.
• Technology Mission for Integrated Development of Horticulture in the North East (2001-02), later folded into MIDH: fruits, vegetables and spices for nutrition and income.
• National Food Security Mission (2007): area expansion and productivity gains in rice, wheat, pulses and coarse cereals.
• New generation: NMEO-Oil Palm (2021), NMEO-Oilseeds (2024, ₹10,103 crore over 2024-25 to 2030-31), a pulses self-reliance mission, the Digital Agriculture Mission and a natural farming mission.

Role in food security

• Availability: record foodgrain output and lower import dependence in mission crops; NFSM underpins the grain security on which the PDS rests.
• Nutrition and stability: pulses, oilseeds, horticulture and millets diversify diets and steady prices.
• Gaps: edible oil and pulse imports continue; rain-fed regions lag; seed replacement and market links stay weak; intensive cropping strains water and soil.

Missions deliver when technology meets assured markets; the next phase must target climate-resilient, rain-fed and nutrition-rich crops.

Farmers often receive a small share of the consumer's rupee because produce passes through many hands and poorly equipped markets before it reaches the buyer.

Sources of inefficiency

• Market structure: too few regulated mandis, far apart, with fragmented market areas and licensing that limits competition among traders.
• Intermediation: long chains of commission agents, buyer cartels, arbitrary deductions and delayed payments.
• Infrastructure: inadequate storage, cold chains, grading and transport cause post-harvest losses and force distress sales at harvest.
• Information and scale: smallholders with tiny marketable surpluses and no price information have little bargaining power, so price discovery stays opaque.

How e-commerce reduces it

• e-NAM (2016), now covering 1,656 mandis in 23 States and 4 UTs: online bidding widens the buyer base and gives transparent price discovery, direct online payment and scope for inter-mandi and inter-state trade.
• Aggregation and access: FPOs sell on e-NAM and ONDC; B2B agritech platforms link farms to processors and retailers; direct farm-to-consumer sales cut out layers.
• Finance: electronic warehouse receipts let farmers store, borrow and sell later instead of at harvest-time lows.
• Limits: weak assaying, little actual inter-state trade, the digital divide and logistics gaps; online markets work only on physical infrastructure.

Digital markets cut transaction costs only when backed by grading, storage, logistics and farmer aggregation through FPOs.

In the mid-1960s India lived 'ship to mouth' on PL-480 wheat imports; the Third Advance Estimates put 2025-26 foodgrain output at a record 376.563 million tonnes.

From scarcity to surplus

• Green Revolution (mid-1960s onward): high-yielding wheat and rice varieties, fertilisers and assured irrigation in Punjab, Haryana and western Uttar Pradesh.
• Institutions: MSP and procurement through the Agricultural Prices Commission and the Food Corporation of India (both 1965), a public distribution system that absorbed the surplus, institutional credit, and research through ICAR and state agricultural universities.
• Later drivers: irrigation expansion and rural electrification, the National Food Security Mission (2007), better seeds, and the Yellow (oilseeds), White (Operation Flood) and Blue (fisheries) revolutions that widened the food basket.
• Result: self-reliance in cereals, buffer stocks for the PDS and rice exports, though gains were concentrated in irrigated regions and in rice and wheat.

Policies for diversification

• Crops: the Mission for Integrated Development of Horticulture; the National Mission on Edible Oils for oilseeds and oil palm; a pulses mission; the millets drive around the International Year of Millets 2023; the Crop Diversification Programme under RKVY in the original Green Revolution states.
• Allied sectors: National Livestock Mission, Rashtriya Gokul Mission for indigenous cattle, PM Matsya Sampada Yojana for fisheries and the National Beekeeping and Honey Mission.
• Enablers: Farmer Producer Organisations for scale, e-NAM for markets, micro-irrigation under Per Drop More Crop, food processing under PM Kisan SAMPADA Yojana, and natural farming.
• Concerns: MSP and procurement still favour rice and wheat, depleting groundwater and soil health and leaving nutrition gaps; incentives must become crop-neutral.

Having secured calories, policy must now secure nutrition, farm incomes and sustainability through diversification that pays the farmer as well as paddy does.

Climate-smart agriculture seeks higher productivity, adaptation to climate risk and lower emissions at once; India's space programme supplies much of the data that make all three possible across small and scattered holdings.

Climate-smart farming from space

• Weather and early warning: INSAT-3D, 3DR and 3DS observations feed IMD forecasts, cyclone tracks, heat and rainfall alerts and district agro-advisories, letting farmers time sowing, irrigation and harvest.
• Seeing through the monsoon: radar satellites such as EOS-04 image crops and floods through cloud; NISAR, launched in July 2025 with NASA, adds soil moisture and land-deformation data.
• Precision inputs: vegetation and moisture indices with NavIC positioning guide water, fertiliser and pest management — cutting costs, emissions and groundwater draw.
• Water and land planning: satellite mapping of groundwater, watersheds and soil supports drought-proofing, water budgeting and soil health cards.

Food security

• Crop forecasting: the FASAL programme and the Mahalanobis National Crop Forecast Centre combine satellite, weather and field data for pre-harvest estimates that guide procurement, buffer stocks and trade decisions.
• Drought and disaster: satellite drought assessment (NADAMS) and flood mapping trigger relief; satellite-based yield estimation speeds up PMFBY insurance settlements.
• Decision platforms: Bhuvan and Krishi-DSS (2024), built with the Department of Space, put crop maps, soil, weather and reservoir data on one geospatial platform for planners and extension workers.

Limits

• Resolution and small plots: free imagery cannot resolve tiny, fragmented fields; ground-truthing is thin, so estimates carry error.
• Last mile: data reach departments more than farmers; smallholders need a vernacular advisory on a phone, not a satellite image.
• Cost and capacity: analytics, high-resolution commercial data and trained agronomists are scarce; data governance and farmer privacy remain unsettled.

Satellites give India a strategic edge in climate-resilient farming; that edge becomes food security only when data flow through extension services, FPOs and digital public platforms to the farmer's field.

High-value crops — fruits, vegetables, spices, flowers, medicinal and aromatic plants — earn several times more per hectare than cereals, and India's horticulture output reached 3707.38 lakh tonnes from 301.36 lakh hectares in 2024-25. Yet the shift is uneven, because a farmer's choice turns on far more than price.

Market and price factors

• Demand pull: rising incomes, urbanisation and diet diversification; nearness to cities, highways, processing units and export channels — Nashik grapes, Jalgaon bananas.
• Price signals: assured MSP and procurement keep farmers in wheat and paddy, while most high-value crops have no price floor and see periodic crashes in onion and tomato.

Resource and risk factors

• Agro-climate and water: apples in the hills, spices in the Western Ghats; assured or micro-irrigation is often the deciding factor.
• Perishability and risk: pests, weather and thin cold chains, with weak insurance cover, make small farmers risk-averse.
• Capital and knowledge: higher input and working-capital needs, access to credit, quality planting material and extension advice.

Institutional and household factors

• FPOs, contract farming, e-NAM, processing and export clusters lower transaction costs; MIDH supports area expansion.
• Farm size and tenure: marginal farmers put household food security first; tenants avoid long-gestation orchards.

Diversification will follow de-risking — cold chains, FPO aggregation, price stabilisation and insurance — rather than price incentives alone.

Supply chain management links production, aggregation, storage, processing, transport and retail so that produce reaches the consumer with the least loss and the largest share of value for the farmer.

Scope

• Before harvest: input supply, crop planning tied to demand, contract farming and aggregation through FPOs.
• After harvest: grading, packaging, warehousing and warehouse receipts, cold chains and reefer transport, processing, e-NAM trading, retail and export logistics.
• Cross-cutting: quality standards, traceability, market intelligence and digital platforms such as the agri-stack.

Significance

• Farmers: better price realisation and a larger share of the consumer rupee as intermediary layers shrink.
• Loss reduction: the NABCONS study (reference years 2020–22) estimated post-harvest losses of 6.02–15.05% for fruits and 4.87–11.61% for vegetables, mainly from poor handling, storage and transport.
• Food security and prices: buffer-stock and PDS logistics; smoothing tomato, onion and potato price spikes under Operation Greens.
• Value addition and exports: processing linkages, traceability and standards create rural jobs and export earnings.
• Gaps to close: fragmented holdings, cold storage concentrated in a few States and APMC distortions — addressed through PM Kisan SAMPADA, the Agriculture Infrastructure Fund and warehouse-receipt finance.

A farm-to-fork chain built on FPOs, cold chains and digital markets can raise farm incomes while cutting waste and food inflation at the same time.

India is the world's largest user of groundwater. Nationally, extraction is about 61% of the extractable resource (60.63% in the 2025 assessment), but 730 of 6,762 assessment units are over-exploited — the average hides a crisis in the north-west and the hard-rock peninsula.

Factors behind depletion

• Irrigation dominance: most extraction goes to farms, and water-hungry paddy and sugarcane are grown in semi-arid Punjab, Haryana and Maharashtra.
• Perverse incentives: free or flat-rate farm power, MSP procurement tilted to paddy and wheat, and cheap borewells make pumping the rational private choice.
• Urban and industrial demand: paved surfaces cut recharge while cities and industries extract with little regulation.
• Hydrogeology and climate: the peninsula's hard-rock aquifers store little; erratic and intense rainfall reduces recharge.
• Governance gaps: groundwater rights tied to land ownership, negligible metering, weak State regulation and fragmented data.

Government steps

• Community demand management: Atal Bhujal Yojana in water-stressed blocks, with incentives for States and villages that plan and save water.
• Recharge: Jal Shakti Abhiyan: Catch the Rain, Amrit Sarovar ponds, and check dams and recharge structures built with MGNREGS funds in over-exploited blocks.
• Regulation and knowledge: CGWA extraction guidelines (2020) for industry and infrastructure, national aquifer mapping, and a model groundwater bill for States.
• Farm-level: Per Drop More Crop micro-irrigation and State incentives for diversification away from paddy.

Lasting recovery needs a shift from supply to demand management — crop diversification, farm-power pricing reform and community management of aquifers as the unit of planning — before more blocks cross the line.

Nanotechnology works at 1–100 nanometres, where materials gain very high surface area and reactivity — letting farm inputs be delivered in smaller, targeted doses and crops be monitored in real time.

Advancements in agriculture

• Nano-fertilisers: nano urea and nano DAP as foliar sprays aim at higher nutrient-use efficiency and lower bulk use; ICAR trials at 20 locations found nano urea usable as a foliar top-dressing in place of conventional urea.
• Crop protection: nano-pesticides and controlled-release formulations cut chemical loads, residues and runoff.
• Precision farming: nano-sensors read soil moisture, nutrients and pest pressure in real time, guiding drone-based spraying and irrigation.
• Seeds, soil and water: nano-coatings for germination and protection, hydrogels that hold soil moisture, and nano-filters for clean irrigation and drinking water.
• Post-harvest: nano-packaging and edible coatings extend shelf life; sensors flag spoilage — fewer losses between farm and market.

Uplifting farmers' socio-economic status

• Lower costs: smaller, lighter inputs cut input, transport and storage costs for the farmer, and the fertiliser subsidy and import burden for the exchequer.
• Higher and better output: precision dosing raises yield and quality, earning premium prices in domestic and export markets.
• Health and environment: fewer residues and less runoff mean safer produce, cleaner water and healthier farm workers.
• New rural livelihoods: drone-spraying and sensor services open jobs for rural youth and women's self-help groups trained as operators.
• Resilience: hydrogels and sensors help smallholders cope with erratic rain; fewer post-harvest losses mean steadier income.
• Caveats: field results are mixed and need independent long-term trials; biosafety and toxicity rules must keep pace; cost and awareness limit uptake among smallholders.

Nanotechnology can make farming input-lean and precise — if its benefits are proven in independent field trials and delivered through extension that reaches smallholders.

Millets — jowar, bajra, ragi and the minor millets — are hardy dryland grains that India has recast as 'Shree Anna' and nutri-cereals; on India's proposal the UN declared 2023 the International Year of Millets.

Role in health

• Nutrient density: rich in dietary fibre, protein and micronutrients — ragi for calcium, bajra for iron — countering the hidden hunger behind anaemia and stunting.
• Lifestyle disease: a low glycaemic index and no gluten make them useful against diabetes and obesity, which now coexist with undernutrition.

Role in nutritional security

• Climate-resilient supply: they grow on marginal rain-fed land with little water or fertiliser, stabilising output in a warming climate.
• Diversifying the plate: they reduce dependence on rice and wheat; inclusion in the PDS, ICDS and PM POSHAN carries better nutrition to the poorest households.
• Livelihoods: they support small and tribal farmers in dryland regions, linking farm income to household nutrition.
• Constraints: low yields, anti-nutrients and short shelf-life that need processing, weak consumer demand and thin procurement still limit their reach.

Pairing demand creation with assured procurement, processing and research will move millets from symbolic promotion to everyday plates — and to lasting nutritional security.

Agriculture uses more than 80% of India's water, yet only about half the net sown area is irrigated — a system that is at once stretched and wasteful.

Major challenges

• Groundwater over-extraction: tubewells dominate irrigation; free or cheap power drives water tables down in Punjab, Haryana and western Uttar Pradesh, and salinity spreads in over-drawn aquifers.
• Low efficiency: flood irrigation and unlined canals lose much of the water, and a persistent gap remains between irrigation potential created and utilised.
• Neglected assets: incomplete projects, silted reservoirs and canals, poor maintenance and low water charges that starve systems of funds.
• Crop–water mismatch: paddy and sugarcane in water-scarce regions, encouraged by assured procurement and power subsidies.
• Climate stress: erratic monsoons, heatwaves and glacial change make both rain-fed and canal supply less predictable; inter-State river disputes add uncertainty.
• Weak governance: fragmented departments, little farmer participation and poor data on actual water use.

Government measures

• PMKSY (2015): AIBP to complete pending projects, Har Khet Ko Pani for new potential and groundwater, watershed development, and Per Drop More Crop for drip and sprinkler (about 115 lakh hectares covered by July 2026).
• Micro Irrigation Fund with NABARD to help States expand drip and sprinkler at concessional cost.
• Atal Bhujal Yojana: community-led groundwater management with water budgets in over-exploited blocks.
• PM-KUSUM: solar pumps and feeder solarisation to replace diesel and reduce the incentive for wasteful pumping.
• Jal Shakti Abhiyan — Catch the Rain: rainwater harvesting, renovation of tanks and recharge structures.
• Governance: Command Area Development, participatory irrigation management through water-user associations, and State incentives for shifting out of paddy in Punjab and Haryana.

Efficiency will come when price and power reforms, crop diversification and micro-irrigation at scale work together to deliver 'more crop per drop'.

For a small farmer, timely information is an input as vital as seed and water; e-technology delivers it cheaply and at scale, from sowing to sale.

In production

• Advisory: Soil Health Cards guide fertiliser use; Meghdoot, mKisan and the Kisan Call Centre deliver weather and crop advisories; FASAL uses remote sensing for crop assessment.
• Precision farming: drones for spraying and field monitoring, sensors, satellite imagery and AI tools that optimise irrigation, nutrients and pest control.
• Inputs and risk: DBT for subsidies, PM-KISAN transfers, Kisan Credit Card credit, and remote-sensing-aided loss assessment for crop insurance claims.

In marketing

• Price discovery: e-NAM links mandis for online bidding, widening the buyer pool beyond local traders.
• Finance and storage: electronic negotiable warehouse receipts let farmers borrow against stored grain instead of distress-selling at harvest.
• Market access: ONDC and mobile apps connect farmers and FPOs directly to buyers; Agmarknet gives daily prices; QR-based traceability opens premium and export markets.

Limits and the bridge

• Patchy connectivity, low digital literacy, small holdings and device costs restrict uptake; FPOs, Common Service Centres and vernacular services can carry the last farmer along.

Technology raises farm incomes when connectivity, skills and collective institutions such as FPOs reach the last farmer.

As incomes rise, Indian households eat less coarse cereal and more fruit, vegetables, milk, eggs and pulses; farmers, meanwhile, plant what prices and procurement reward.

Shifts driven by marketing conditions

• MSP and assured procurement made wheat and rice dominant in Punjab, Haryana and western Uttar Pradesh, while coarse cereals and millets lost area even where they suited the soil.
• Cash crops followed markets: cotton, sugarcane and soybean expanded in Maharashtra, Karnataka and Madhya Pradesh where prices, mills and assured cane payments were favourable.
• Newer channels, e-NAM, contract farming, FPOs, agro-processing and export demand for basmati, spices and oilseeds, pull farmers towards high-value crops; APMC restrictions and price risk hold others back.

Shifts driven by consumption

• Demand for fruit and vegetables has expanded horticulture into a fast-growing segment of farm output.
• Growth in dairy and poultry has raised maize acreage for feed; edible-oil demand has pushed oilseeds and oil palm.
• Pulses and edible oils still fall short of demand because they lacked assured markets, leaving India dependent on imports.

Consequences

• Groundwater depletion in the north-west, soil-health decline under cereal monoculture, and import dependence for pulses and edible oil.

Corrections under way

• Crop diversification programmes, MSP and procurement for millets and pulses, the International Year of Millets 2023, missions for oilseeds and oil palm, and micro-irrigation to make diversification water-wise.

A demand-led, water-wise cropping pattern with assured markets for diverse crops would serve farmers and consumers better than one shaped by cereal procurement alone.

Farmers get a modest share of the consumer's rupee because the chain from farm to market is weak at every link, both before produce reaches the mandi (upstream) and after it leaves (downstream).

Upstream bottlenecks

• Fragmented supply: small, scattered holdings produce small lots with no grading, standards or aggregation, leaving farmers with little bargaining power.
• Information and credit: limited price information, credit and inputs push farmers into distress sales soon after harvest, when prices are lowest.
• Mandi system: too few regulated markets, APMC monopoly, dominance of commission agents, high market fees, cartelisation among traders and delayed payments.
• Regulation: stock limits and export curbs under the Essential Commodities Act and sudden trade-policy swings discourage private investment and add to price volatility.

Downstream bottlenecks

• Intermediaries: many layers between mandi and consumer, each adding margin without adding value.
• Losses: poor rural roads, inadequate warehouses and thin cold chains cause heavy post-harvest losses, especially in fruits, vegetables and milk.
• Processing and retail: low processing levels and weak links between farmers, processors and organised retail keep value addition low.
• Institutions: thin reach of e-NAM, weak farmer producer organisations, limited warehouse-receipt finance and few safeguards in contract farming.

Way forward

• Aggregation through FPOs, APMC reform on the lines of the 2017 model law, e-NAM and direct marketing, the Agriculture Infrastructure Fund for storage and cold chains, and a stable trade policy.

Better aggregation, storage and market access under predictable rules would shrink the farm-to-fork gap and raise the farmer's share of the final price.

Integrated Farming System (IFS) combines crops with livestock, fish, poultry, bees, trees and biogas on a single farm, so that the waste or by-product of one enterprise becomes the input of another.

What IFS is

• A whole-farm, resource-recycling approach: crop residue becomes fodder, dung becomes manure and biogas, and pond water irrigates crops.
• It is planned around the farm's land, water, labour and market, so the mix of enterprises differs by region and farm size, and ICAR has developed location-specific farming-system models.

How it helps small and marginal farmers

• Income through the year: milk, eggs, fish, honey and vegetables bring regular cash between crop harvests.
• Lower risk: if a crop fails, the other enterprises cushion the loss.
• Lower costs: recycling cuts spending on fertiliser, feed and energy, so net income on a small plot rises.
• Higher resource productivity: more output per unit of land, water and labour, which matters most where holdings are tiny.
• Employment and nutrition: work is spread across the year and uses family labour, including women, and the diverse produce improves household nutrition.
• Sustainability: better soil health, less chemical use and greater climate resilience; agroforestry and water harvesting can be added.

Constraints and support

• Start-up capital, skills and market links limit adoption; Krishi Vigyan Kendras, ICAR farming-system models, FPOs, livestock and fisheries schemes and convergence with MGNREGA for farm ponds and cattle sheds help.

For small farms, integration is a practical route to stable income, lower risk and sustainable farming, and it deserves the first claim on extension effort.

Agriculture is the largest user of India's water, mostly through flood irrigation, so farm-level efficiency is central to easing the crisis.

How micro-irrigation helps

• Drip and sprinkler systems deliver water at the root zone, cutting evaporation, runoff and seepage, so each drop and each unit of pumping energy yields more.
• Fertigation delivers nutrients with water, raising yields and cutting fertiliser, weeding and labour costs; it suits undulating, saline and water-scarce land.
• Policy support: Per Drop More Crop under PMKSY (from 2015-16) and the Micro Irrigation Fund with NABARD give subsidy and cheaper finance.

To what extent

• Coverage is still well under a tenth of the net sown area and concentrated in Andhra Pradesh, Gujarat, Karnataka, Tamil Nadu and Maharashtra; paddy, wheat and sugarcane remain flood-irrigated.
• Savings per hectare may not cut basin-level use if farmers use the saved water to expand area, so groundwater regulation must go with it.
• Constraints: high upfront cost for small holdings, clogging and poor servicing, unreliable power and delayed subsidy.
• The crisis also stems from crop choice, free power and urban and industrial demand, so watershed recharge, canal modernisation, wastewater reuse and pricing reform are needed too.

Micro-irrigation is a strong but partial answer: with crop diversification, groundwater governance and finance for small farmers it can carry much of the load; alone it cannot.

Diversification away from the rice-wheat cycle is needed to save groundwater, restore soils, improve diets and raise incomes, yet the structure of incentives keeps farmers where they are.

Present challenges

• Policy bias: assured MSP and open-ended procurement for rice and wheat, with free or cheap power and water, especially in Punjab, Haryana and western Uttar Pradesh, make alternatives look risky.
• Market risk: pulses, oilseeds, fruit and vegetables face price volatility and thin procurement; poor storage, cold chains and processing force distress sales of perishables.
• Farm-level limits: small holdings, weak credit and information, scarce quality seed and know-how for new crops, and pest and climate risk.
• Demand side: consumption and the public distribution system centre on cereals, so millets and pulses lack pull.
• Cost of the status quo: paddy in water-scarce regions depletes groundwater and monoculture degrades soil, so the change cannot wait.

Opportunities from emerging technologies

• Data and sensing: satellite and drone crop mapping, soil sensors and weather-based advisories guide crop choice, input use and timing, lowering the risk of trying a new crop.
• Digital markets: e-NAM (2016), FPO platforms and price-forecasting apps widen the buyer base; traceability and grading help high-value crops reach organised retail and export.
• Biotechnology: climate-resilient, short-duration and biofortified varieties of pulses, millets and oilseeds fit into existing rotations and raise nutrition.
• Precision irrigation and machinery: drip and sprinklers suit horticulture, and custom-hiring of harvesters and planters cuts the cost of switching.
• Enabling policy: technology pays off only with assured procurement of pulses and millets and crop-neutral incentives.

Technology can shrink the risk of leaving rice and wheat, but the price signals must change first; then data, markets and seeds can make diversification the farmer's own choice.

India grows large surpluses of grain, fruit, vegetables and milk, yet the farmer often gets a small share of the consumer's price because produce is hard to move, store and sell.

Transport constraints

• Last-mile roads: weak rural and feeder roads slow movement from farm to market, especially in the monsoon.
• Cold logistics: few refrigerated vehicles and pack-houses, so perishables spoil in transit; rail and waterways are barely used for farm produce.
• Cost: high freight and handling charges eat into the margin on small consignments.

Marketing constraints

• Storage: too few warehouses and cold stores near farms force distress sales right after harvest and cause heavy post-harvest losses of fruit, vegetables, milk and fish.
• Market structure: regulated mandis are few and far apart, commission agents dominate, and small farmers sell to village traders at low prices.
• Fragmented holdings: a small marketable surplus makes grading, standardisation and collective bargaining hard and weakens credit against stored produce.
• Information: e-NAM's own objectives name the gap, information asymmetry between farmer and trader and weak price discovery, and its reach is still uneven.

Rural roads, cold chains, aggregation through FPOs and open, transparent markets such as e-NAM would raise the farmer's share of the consumer's rupee and cut waste.

India is among the world's largest producers of milk, pulses, fruit and vegetables, yet only a small share is processed; that gap is both the sector's challenge and its opportunity.

Challenges

• Fragmented supply chains and weak cold storage and transport, so raw material arrives late, damaged or not at all.
• Small, scattered units with low technology, weak grading and quality standards, and thin credit.
• Seasonal, perishable supply and price swings, high logistics costs and the cost of food-safety compliance.

Opportunities

• Rising urban incomes and demand for packaged and ready-to-eat food, export potential, and a large domestic raw-material base.
• Rural non-farm jobs close to production clusters.

Raising farm incomes

• Value addition: processed products fetch more than raw produce, and farmers share the gain when linked as suppliers or owners through FPOs and cooperatives.
• Less waste: processing and cold chains near the farm cut post-harvest loss, so more of the harvest is sold.
• Assured demand: contract farming with assured procurement and grading at source give steady offtake and better prices.
• Diversification: demand for processable fruit, vegetables, pulses and milk lets farmers move beyond low-value cereals.
• Support: PM Kisan SAMPADA Yojana (mega food parks, cold chains), the PMFME scheme for micro units, and liberal FDI norms.

A strong processing sector can turn surplus into income and jobs, provided supply chains, credit and quality standards are built alongside.

From the food on the plate and the vaccine in the arm to the phone in the hand, science and its technologies shape daily life, usually without being noticed.

Science in everyday life

• Health: vaccines, antibiotics and diagnostics have lengthened lives; clean water and sanitation rest on chemistry and microbiology.
• Connectivity and money: mobile phones, the internet and UPI payments run on semiconductors and satellites.
• Energy and home: electricity, LEDs, refrigeration and household appliances; weather forecasts and ISRO's remote-sensing services guide farmers, fishermen and disaster response.
• Mind and State: scientific temper, a fundamental duty under Article 51A(h), and evidence-based, data-driven governance.

Striking changes in agriculture

• Green Revolution: high-yielding dwarf wheat and rice, with fertiliser and assured irrigation, turned food deficit into self-sufficiency in foodgrains.
• Biotechnology and breeding: Bt cotton (2002), hybrids, tissue culture and improved livestock breeds; Operation Flood helped make India the largest milk producer.
• Precision and digital farming: drones, satellite crop and soil monitoring, soil health cards, weather advisories, e-NAM and mobile advisory apps.
• Water and inputs: drip and sprinkler irrigation, bio-fertilisers, integrated pest management, cold chains and climate-resilient seeds.
• The cost: soil and groundwater damage, pesticide residues, monoculture and biodiversity loss, and unequal access.

Science is woven into every part of life; in agriculture its next task is to move from raising yield alone to sustainable and shared gains.

• Focus on 1,592 water-stressed blocks in 256 districts, where teams of central officers work with the district administration.
• Two phases in 2019: 1 July to 15 September during the monsoon, and 1 October to 30 November for states that receive the retreating north-east monsoon.

Five interventions

• Water conservation and rainwater harvesting; renovation of traditional water bodies and tanks; reuse of water and recharge structures for borewells; watershed development; intensive afforestation.

Delivery

• A collaborative effort of Union ministries and state governments, coordinated by the Department of Drinking Water and Sanitation, with block and district water conservation plans.
• Krishi Vigyan Kendras promote efficient irrigation and better crop choices, and a large communication campaign draws citizens in.

Later phases and links

• From 2021 the campaign continued as JSA: Catch the Rain, covering all districts, rural and urban.
• It complements the Jal Jeevan Mission (tap water for rural homes) and the Atal Bhujal Yojana (community groundwater management).

JSA works when conservation becomes local: recharge, reuse and community ownership build water security where the rain falls.

The rice-wheat system of the Indo-Gangetic plains, led by Punjab, Haryana and western Uttar Pradesh, turned India from a food-deficit importer into a foodgrain-surplus nation; the same system now strains its water, soil, air and farm economy.

Factors behind the success

• Technology: high-yielding dwarf varieties of wheat and rice that respond to fertiliser, with pesticides and mechanisation, raised yields sharply.
• Agro-ecology: fertile alluvial soils and assured irrigation from canals and tubewells; kharif rice followed by rabi wheat fits the climate and the crop calendar.
• Price and procurement: assured MSP and open-ended procurement by the FCI gave a guaranteed buyer at a guaranteed price for both crops.
• Input support: subsidised power, fertiliser and credit lowered costs, while ICAR and the agricultural universities supplied research and extension.
• Farmers: enterprising cultivators adopted the package quickly, and the two crops fitted well into a mechanised annual cycle.

How it became a bane

• Water: paddy is water-hungry, and free or cheap power for tubewells has pulled groundwater down to critical depths in Punjab and Haryana.
• Soil: heavy urea use has skewed the nutrient balance, organic matter has fallen, salinity and waterlogging affect canal commands, and yield growth has slowed.
• Air and climate: burning of paddy stubble in October-November thickens north India's winter smog, and flooded paddies emit methane.
• Economy: monoculture crowds out pulses, oilseeds and millets, grain stocks pile up beyond need, and farmers stay locked into MSP dependence at a rising fiscal cost.
• Biodiversity and health: loss of crop and varietal diversity, pest build-up and pesticide residues.

Way forward

• Crop diversification backed by MSP and procurement for pulses, oilseeds and millets; direct-seeded rice and shorter-duration varieties; in-situ straw management; and reformed power and fertiliser incentives.

The system fed the nation; keeping it sustainable now means rewarding water saved and crops diversified rather than grain alone.

With per-capita water availability falling and groundwater depleting, India must both hold more of the monsoon where it falls and get more crop from every drop it stores.

Improving water storage

• Revive local storage: desilt and restore tanks, ponds and traditional structures; build check dams, farm ponds and percolation tanks under watershed programmes.
• Recharge aquifers: rainwater harvesting, managed aquifer recharge and watershed treatment, with community-led groundwater management as under the Atal Bhujal Yojana.
• Large storage: manage dams for multiple uses, desilt reservoirs and complete pending projects so that created capacity is actually used, as the AIBP component of PMKSY aims to.
• Reuse: treat urban wastewater and channel it to peri-urban irrigation, adding to supply without new abstraction.

Improving the irrigation system

• Efficient application: drip and sprinkler systems under Per Drop More Crop (PMKSY), laser land levelling, and canal lining and modernisation to cut seepage.
• Command-area works: field channels and on-farm development so that water released from dams reaches the tail end.
• Cropping choices: shift from water-intensive paddy and sugarcane in dry regions to millets, pulses and oilseeds, backed by MSP and procurement for them.
• Pricing and institutions: rational power tariffs and feeder separation, volumetric pricing of canal water, water user associations, and regulation of groundwater extraction.
• Technology: soil-moisture sensors, satellite advisories and village-level crop-water budgets so that irrigation follows need, not habit.

More storage and recharge must go with efficient use, right pricing and community management if irrigation is to survive a drier future.

An Integrated Farming System links crops with livestock, fish, poultry, bees or trees on one holding, so that the by-product of one enterprise becomes the input of another.

How IFS sustains production

• Recycling: crop residue feeds animals, dung and slurry return as manure or biogas, pond silt fertilises fields; purchased inputs fall and soil health improves.
• Efficiency: land, water and family labour work through the year, raising output per hectare and cutting dependence on chemicals.
• Stable income: several enterprises spread weather and price risk and give year-round cash and employment, most useful for small and marginal holdings, the vast majority of Indian farms.
• Resilience and nutrition: mixed systems buffer drought and flood losses, fit organic farming and agroforestry, and diversify the family diet; ICAR's farming-systems research and rainfed-area programmes promote such models.

Where it falls short

• It needs capital, skills, labour and market links; gains vary with land, water and location; weak extension and credit gaps slow adoption.
• It complements, rather than replaces, productivity gains in the main cereal belts.

IFS goes a long way towards sustaining production and livelihoods on small farms, but only where credit, training, extension and markets make it workable.

Watershed development treats a drainage basin as one unit, conserving rain, soil and vegetation from ridge to valley. India applied it to rainfed farmland through NWDPRA (1990-91), then the Integrated Watershed Management Programme, and now PMKSY's watershed component.

Impact on production

• Water: check dams, farm ponds, contour bunds and trenches slow run-off and recharge groundwater, so wells last longer and soil moisture carries crops through dry spells.
• Soil: erosion control and vegetative cover retain topsoil and organic matter, restoring the productivity of degraded land.
• Cropping: protective irrigation makes a second crop possible, lifts yields and allows a shift to horticulture, fodder and livestock in dry districts.
• Stability: steadier output and income against rainfall variability, wage work during construction, greener commons and, in many villages, less distress migration.
• Institutions: village watershed committees plan and maintain works, building local ownership of the assets.

Where results fall short

• Gains fade where structures go unmaintained, participation is weak, better-off farmers capture the recharge, or the monsoon fails altogether; rainfed yields still trail irrigated ones.

Watershed programmes have made rainfed farms more productive and resilient; lasting impact depends on community upkeep and convergence with MGNREGS and PMKSY.

Visvesvaraya built the water systems that made dry land farmable; Swaminathan raised what that land could yield. Together they form one chain from water to food.

Sir M. Visvesvaraya: water engineering

• Block system of canal irrigation in the Deccan, rationing water by turns so that more land was irrigated from the same flow.
• Automatic reservoir sluice gates that raised storage safely; chief engineer of the Krishnaraja Sagara dam on the Cauvery, which supplies irrigation and drinking water to this day.
• Flood-protection system for Hyderabad; planning by data, economy and technical education; Engineers' Day on 15 September honours him.
• Benefit: secure cultivation in dry tracts, city water supply, and a model of engineering-led public works.

Dr M. S. Swaminathan: agricultural science

• Led the adaptation and spread of high-yielding wheat and rice as head of IARI and ICAR, turning the Green Revolution into food self-sufficiency after the shortages of the 1960s.
• Chaired the National Commission on Farmers, which urged MSP at least 50 per cent above the cost of production; argued for an 'evergreen revolution' that sustains yields without harming soil and water.
• Benefit: higher yield per hectare, food security and higher farm incomes, and a farmer-centred policy agenda.

One gave India its water systems, the other its seeds and farm-policy ideas; together they anchor irrigation-led, science-led agriculture and food security.

Food processing adds value to farm produce, cuts post-harvest waste and creates jobs off the farm, yet India processes only a small share of what it grows; the Ministry of Food Processing Industries leads the policy response to this gap.

The challenges

• Low processing of perishables and high post-harvest losses; thin cold chains and fragmented farm-to-factory linkages; small unorganised units; uneven quality standards; limited credit and skills.

Policy response

• Infrastructure: Pradhan Mantri Kisan SAMPADA Yojana (2016-20, Rs 6,000 crore) funds mega food parks, integrated cold chains, processing units, agro-processing clusters, backward and forward linkages, food-safety laboratories and skills.
• Price and supply stability: Operation Greens (2018) for tomato, onion and potato value chains, to cut wastage, stabilise prices and link growers to processors.
• Investment and credit: 100 per cent FDI is allowed in food processing, and a special NABARD fund gives cheaper credit to food parks and agro-processing units.
• Quality and safety: the Food Safety and Standards Act, 2006 and FSSAI licensing, standards and testing laboratories raise quality for domestic and export markets.
• Markets: the Agriculture Export Policy, 2018 and World Food India events promote processed-food exports and attract investors.
• Since then: the scheme for formalising micro food processing enterprises (2020) and a production-linked incentive scheme (2021) support small units and Indian brands.

Assessment

• The mix addresses the supply side, but last-mile cold chains, farmer-processor contracts, skills and steady domestic demand for processed food remain weak, so the assets created do not yet deliver their full value.

Infrastructure, credit, standards and price stabilisation tackle the supply side; the sector will grow when farmer-processor links, last-mile cold chains, skills and demand for value-added food are built together.

Biotechnology applies biological knowledge, from genes to microbes, to make crops, livestock and inputs more productive and resilient. For a farmer it can mean more output per acre, lower input bills, fewer losses and new sources of income, all of which lift living standards.

Higher and more stable output

• Pest-resistant varieties: Bt cotton, approved in March 2002, cut bollworm damage and raised output; marker-assisted breeding speeds the release of improved varieties.
• Stress tolerance: crops bred for drought, salinity, flood and pests protect incomes in rainfed and coastal areas, and genome editing offers faster, targeted improvement.
• Tissue culture: disease-free, uniform planting material for banana, sugarcane, potato and flowers raises yield and quality; national certification of tissue-culture plants protects growers.

Lower costs and healthier soils

• Bio-inputs: biofertilisers, biopesticides and bio-control agents cut chemical bills, restore soil health and support organic and natural farming.

Livestock and fisheries

• Vaccines and diagnostics, artificial insemination, embryo transfer and improved fish strains raise milk and fish output and cut disease losses, the mainstay of landless and small households.

Nutrition and income beyond the field

• Biofortified crops tackle hidden hunger in farm families; bio-processing and waste-to-energy add income beyond the farm gate.

Concerns to manage

• Seed costs and corporate control; pest resistance, as with pink bollworm in Bt cotton; biosafety and biodiversity risks; and public trust. GEAC regulates approvals, and the Department of Biotechnology's Biotech-KISAN programme links scientists with farmers so that technology reaches the field with support.

Biotechnology can raise yields, incomes and nutrition, provided farmers get affordable, safe and well-regulated technology with extension support, as Biotech-KISAN tries to ensure.

Minimum Support Price is the floor price at which the government stands ready to buy specified crops, announced before sowing on the advice of the Commission for Agricultural Costs and Prices (CACP).

What MSP means

• Announced for 23 crops; CACP weighs cost of production, demand and supply, market trends and parity between crops.
• Cost basis: Budget 2018-19 promised MSP of at least one and a half times production cost; the Swaminathan Commission had suggested C2 cost plus 50 per cent, while kharif 2018 MSPs used the narrower A2+FL cost.

How it can break the low-income trap

• Price assurance: a guaranteed floor removes the fear of a post-harvest collapse and cuts distress sales.
• Investment: assured returns let farmers spend on quality seed, inputs and technology, raising productivity and income.
• Crop choice: a remunerative price improves creditworthiness and encourages pulses and oilseeds, where MSPs were raised.

Conditions for success

• Procurement reach: over 86 per cent of farmers are small and marginal, and procurement centres on wheat and rice in a few States, so most farmers sell below MSP.
• Deficiency payment: the Budget asked NITI Aayog to design a mechanism for when prices fall below MSP; e-NAM and rural markets must widen.
• Risks: fiscal cost, bias toward water-hungry rice and wheat, stock build-up.

MSP can cushion prices and support income; escaping the trap also needs wider procurement, lower costs, diversification and non-farm jobs.

Fruits and vegetables in India usually pass through several traders and commission agents between the farm and the consumer, losing value and freshness at each step; supermarkets shorten that chain by managing it end to end.

Role in supply chain management

• Direct sourcing: buying from farmers, farmer producer organisations or through contract farming at collection centres close to the farm.
• Post-harvest functions: grading, sorting, packing, cold storage and refrigerated transport cut wastage and lengthen shelf life.
• Scale and planning: demand forecasting, bulk purchase, private labels and bar-coded traceability give price stability, food safety and assured offtake to suppliers.

How intermediaries are eliminated

• The mandi's commission agent, wholesaler and sub-wholesaler are bypassed when the retailer buys at the farm gate and delivers to its own stores.
• Own warehouses and logistics replace the transporter and the local trader; the gap between farm-gate and retail price narrows, and the farmer's share can rise.

Limits

• Organised retail covers a small part of an unorganised market; small farmers struggle with quality standards, and bulk buyers can delay payment or squeeze suppliers.
• Public support is needed: FPOs, e-NAM, upgraded rural haats and Operation Greens (Budget 2018-19, ₹500 crore) for tomato, onion and potato, with mandi reform and cold-chain investment.

Supermarkets compress the chain and reduce waste; farmers keep the gain only when aggregation, fair contracts and market reform run alongside.

Sikkim began withdrawing chemical fertilisers and pesticides from its farms in 2010 and was declared India's first fully organic State in January 2016; the Economic Survey 2023-24 calls it the first such State in the world.

Ecological benefits

• Soil health: more organic matter, better water retention and microbial life, and less erosion on Himalayan slopes.
• Clean water and biodiversity: no chemical run-off into streams and groundwater, so pollinators, birds and beneficial insects return in a fragile ecosystem.
• Climate: lower energy use and emissions from fertiliser manufacture, and soils more resilient to erratic rain.

Economic benefits

• Premium prices and a State brand for large cardamom, ginger, turmeric and buckwheat, with export potential.
• Lower input costs once compost, bio-fertilisers and local seed replace purchased chemicals.
• Health and jobs: safer food, less chemical exposure for farm workers, and farm tourism and homestays built on the organic identity.
• Model for others: Paramparagat Krishi Vikas Yojana and the North-East organic value-chain mission back cluster-based conversion; Tripura and Uttarakhand have set similar targets.

Limits

• Yield dips during transition, certification and marketing costs, shortage of organic manure, and food-security concerns for larger, food-deficit States.

Sikkim shows that organic conversion can protect a fragile ecosystem and raise incomes; scaling it needs research on yields, certification support and assured markets.

The National Horticulture Mission, launched in 2005-06, aimed at holistic growth of horticulture through area expansion, quality planting material and post-harvest infrastructure; since 2014-15 it runs within the Mission for Integrated Development of Horticulture.

Role in production and productivity

• Inputs: quality planting material and area expansion under fruits, vegetables and other horticulture crops.
• Technology: protected cultivation, micro-irrigation, integrated pest management and organic practices raised yields per hectare.
• Post-harvest: pack-houses, cold storage and market infrastructure reduced losses and lengthened the selling window.
• Outcome: horticulture output overtook foodgrains; official data put horticulture output at about 300 million tonnes in 2016-17 against about 275 million tonnes of foodgrains (since then, 3707 lakh tonnes on 301 lakh hectares in 2024-25, per the Agriculture Ministry).

Role in income

• Horticulture yields more value per hectare than cereals and employs labour through the year; growers with cold chains, markets and processing nearby earn more, and cluster development helps small growers reach scale.

How far incomes have risen

• Uneven: gains concentrate where markets and cold chains exist; small holdings, weak market links and delayed subsidy release limit the spread.
• Price risk: gluts of tomato, onion and potato crash prices, and intermediaries capture margins, so higher output has not meant proportionately higher realised income.
• Evidence gap: data on net farm income from horticulture is thin, and benefits vary across States and crops.

Way forward

• Farmer producer organisations, Operation Greens (2018) for tomato, onion and potato, e-NAM, food processing and cold chains, crop insurance and market intelligence.

NHM has lifted horticulture's output and diversified Indian farming, but incomes rise durably only when cold chains, markets and processing let farmers keep more of the value they create.

Assured procurement and subsidised inputs tilted India's cropping pattern towards rice, wheat, sugarcane and cotton, while hardy, nutritious millets lost ground; the push for millets seeks to reverse that.

How emphasis changed cropping patterns

• Rice and wheat: MSP with assured procurement, plus subsidised power, water and fertiliser, made the pair dominant in Punjab, Haryana and western Uttar Pradesh, displacing coarse cereals, pulses and oilseeds.
• Other shifts: sugarcane spread in Maharashtra and Karnataka on assured cane prices; Bt cotton after 2002 raised cotton's area; soybean grew across central India; pulses and oilseeds lagged, leaving import dependence.
• Consequences: groundwater depletion in the north-west, soil fatigue, monoculture, crop-residue burning, nutrition gaps and regional imbalance; millets' area shrank as cheap PDS rice and wheat replaced them on plates.

Emphasis on millets: production

• Why: jowar, bajra, ragi and minor millets need little water and few inputs, grow in rainfed and dry areas and withstand heat, which makes them climate-resilient crops.
• Policy: millets were notified as nutri-cereals in April 2018; a nutri-cereals sub-mission under the National Food Security Mission began in 2018-19; MSPs for millets were raised in 2018-19.

Emphasis on millets: consumption

• Nutrition: rich in fibre, iron and calcium, millets can close nutrition gaps that a rice-and-wheat diet leaves open.
• Barriers: taste habits, laborious processing, short shelf life and the PDS bias towards rice and wheat.
• Measures: procurement of millets for the PDS, school meals and anganwadis; value-added products, branding and ready-to-eat forms; awareness campaigns.

Way forward

• Crop-neutral incentives, research on millet yields, and matching crops to agro-climatic zones and nutrition needs.

Aligning crop choice with agro-climatic zones and nutrition, through MSP, procurement and PDS reform, can save water and improve diets; millets are the practical starting point.

After independence India moved from ship-to-mouth imports under PL-480 to self-sufficiency in foodgrains, and then diversified into milk, fish, oilseeds and horticulture through campaign-style 'revolutions'.

The revolutions

• Green Revolution (mid-1960s): high-yielding wheat and rice, fertilisers, irrigation and assured procurement prices, mainly in Punjab, Haryana and western Uttar Pradesh; foodgrain output reached a record 275.68 million tonnes in 2016-17.
• White Revolution (Operation Flood, 1970): cooperative dairying under the NDDB, led by Verghese Kurien, made India one of the largest milk producers.
• Blue (fisheries), Yellow (oilseeds), Golden (horticulture), Pink (meat and prawns) and Silver (eggs and poultry) revolutions widened the food basket.

Food security

• Surplus grain built buffer stocks and fed the public distribution system; famine deaths and import dependence ended, and the National Food Security Act, 2013 could promise subsidised grain to two-thirds of the population.
• Cheaper milk, eggs, fish and vegetables improved nutrition beyond calories.

Poverty alleviation

• Higher yields raised farm incomes and rural wages; dairy gave small and landless households, especially women, a steady daily cash income.
• Lower food prices raised the real incomes of the poor, while agro-processing and input industries created non-farm jobs.
• Limits: gains were regional and crop-specific; groundwater depletion, soil fatigue and neglect of pulses and rain-fed areas call for M.S. Swaminathan's 'evergreen revolution'.

These revolutions gave India food security and raised rural incomes; the next phase must be sustainable, regionally balanced and built around small farmers.

The UN General Assembly declared 2016 the International Year of Pulses, with FAO as lead agency, under the slogan 'nutritious seeds for a sustainable future', because pulses serve nutrition and sustainability at once.

Nutritional and health advantages

• Pulses are rich in protein, fibre, iron and folate and low in fat, giving affordable protein where animal foods are costly.
• A low glycaemic index and high fibre help manage diabetes, heart disease and obesity, and suit vegetarian diets.

Agronomic and environmental advantages

• Root-nodule bacteria fix atmospheric nitrogen, so pulses in rotation or intercropping cut fertiliser need and raise the yield of the following crop; FAO highlighted this as a way to reduce dependence on synthetic fertilisers.
• Most pulses need less water than cereals, tolerate drought and have a low carbon footprint, which suits rainfed farming under climate stress.

Economic and food-security advantages

• Short-duration crops fit cropping systems, residues serve as fodder, and pulses give small farmers extra income and a hedge against cereal risk.
• Dry pulses store for long periods, aiding food security; India is the largest producer and consumer yet still imports to meet demand.

By joining nutrition, soil health and climate resilience in one crop group, pulses earned a dedicated year and remain central to sustainable food systems.

The rice-wheat system of the Indo-Gangetic plains delivered the Green Revolution, but four decades of the same two cereals on the same fields have brought yield stagnation and rising input costs, most sharply in Punjab and Haryana.

Why yields are declining

• Soil fatigue: continuous cereal cropping mines nutrients; organic carbon and micronutrients such as zinc fall, and nitrogen used far out of proportion to phosphorus and potash lowers the response to fertiliser.
• Water: flooded paddy draws heavily on groundwater and free power encourages over-pumping, so water tables fall while canal tracts suffer waterlogging and salinity.
• Biotic stress: monoculture builds up pests and diseases and has produced herbicide-resistant Phalaris minor in wheat; stubble burning destroys soil life and fouls the air.
• Climate: terminal heat during grain filling cuts wheat yields, and an erratic monsoon delays paddy transplanting, which squeezes the wheat sowing window.
• Technology plateau: the yield potential of Green Revolution varieties is largely exhausted and new varieties reach farmers slowly.
• Policy lock-in: assured procurement at minimum support prices for rice and wheat makes every other crop the riskier choice.

How diversification stabilises yields

• Soil renewal: pulses in rotation fix nitrogen and add organic matter; deep-rooted crops improve soil structure, so cereal yields recover in the following season.
• Breaking cycles: a change of crop interrupts pest, disease and weed cycles and reduces pesticide use.
• Water balance: maize, pulses and oilseeds need far less water than paddy, easing groundwater decline and keeping the system viable.
• Risk spreading: a mix of crops and horticulture spreads weather and price risk and adds income, so one failed crop no longer sinks the farm.
• Policy support: the Crop Diversification Programme, run under RKVY since 2013-14 in Punjab, Haryana and western Uttar Pradesh, helps shift paddy area to maize, pulses, oilseeds and agroforestry; it works only where procurement and markets exist for these crops.

Moving part of the rice-wheat area to pulses, oilseeds and horticulture, backed by prices and markets, can restore soil and water health and steady yields across the whole system.

Subsidies on fertiliser, power, water and credit lower farmers' costs, but they also signal what to grow and how much input to use, and so shape cropping decisions across the country.

Effect of subsidies

• Cropping pattern: cheap urea, free or flat-rate power, subsidised canal water and assured procurement pull farmers towards rice, wheat and sugarcane even where water is scarce, as with paddy in Punjab and sugarcane in Maharashtra.
• Crop diversity: pulses, oilseeds and millets lose area to cereals; monocropping narrows the crop base; the urea bias distorts the nitrogen-phosphorus-potash balance and degrades soil.
• Farm economy: subsidies cut costs and steady incomes, but larger irrigated farms capture most of the benefit; overuse raises costs later through deeper pumping and poorer soils; the fiscal burden crowds out public investment in irrigation, research and markets.

Significance for small and marginal farmers

• Crop insurance: the Pradhan Mantri Fasal Bima Yojana (2016) fixes the farmer's premium at 2 per cent for kharif, 1.5 per cent for rabi and 5 per cent for annual commercial and horticultural crops, with the balance paid by government; it reduces distress borrowing after weather shocks and lets small farmers try higher-value crops, though delayed claims and low awareness limit its reach.
• Minimum support price: a floor that guards against a post-harvest price crash and, where procurement exists, gives income certainty; yet small farmers with little marketable surplus and distant mandis often sell to traders below MSP, and procurement is concentrated in a few States and crops.
• Food processing: cuts post-harvest losses, adds value and provides assured buyers through contract farming and producer organisations; it raises the farmer's share of the consumer price and creates non-farm jobs near villages, which matters where holdings are too small to live on.

Reform direction

• Move to direct income support, bring urea under nutrient-based pricing, extend procurement to pulses and oilseeds, and organise small holders into farmer producer organisations linked to processors.

Support should protect the small farmer without dictating the crop; insurance, wider price support and processing can do that better than open-ended input subsidies.

Irrigation takes most of India's freshwater, yet each unit of water yields less crop than in many countries. Water-use efficiency is the ratio of crop output to the water actually used, popularly 'more crop per drop', measured at field, farm or project level.

Where water is lost

• Conveyance losses: seepage and evaporation from canals and field channels.
• Application losses: runoff, deep percolation and excess flooding in traditional surface irrigation, so only part of the water reaches the root zone.
• Efficiency rises when these losses fall and when each unit of water produces more yield.

Role of micro-irrigation

• Drip: delivers water slowly to the root zone through emitters, cutting evaporation, runoff and deep percolation, suppressing weeds, and allowing fertigation, so nutrient use improves too.
• Sprinklers and micro-sprinklers: spread controlled amounts of water like rain, suited to uneven land, light soils and many field, vegetable and orchard crops.
• Gains: substantial water and energy savings, higher yield and quality, more area irrigated from the same source, and less waterlogging and salinity.
• Support: the Per Drop More Crop component of PMKSY (2015-16) subsidises systems, with improving on-farm water-use efficiency a stated objective (since then, a Rs 5,000 crore Micro Irrigation Fund was created with NABARD in 2018-19).
• Constraints: high upfront cost for small farmers, clogging and maintenance, power needs and delayed subsidies; cereals such as paddy are hard to cover.

Micro-irrigation is the quickest route to higher water-use efficiency, but it must go with better canal management, crop choice matched to water availability, and rational pricing of water and power.

Allelopathy is the effect, harmful or beneficial, that one plant has on another through chemicals it releases into the environment. The term was coined by Hans Molisch in 1937.

What it involves

• Allelochemicals leave plants through root exudates, leaf leachates, volatiles and decaying residues; they affect germination, growth, soil microbes and nutrient cycling.

Beneficial role in irrigated systems

• Weed suppression: residues and mulches of sorghum, sunflower and rye, and allelopathic rice and wheat varieties, reduce weed growth and herbicide use in rice-wheat and other intensive systems.
• Rotation and intercropping: chemicals left by one crop shape the next, so a well-chosen sequence improves yields and pest control, and allelopathic cover crops keep weeds down in sugarcane-based systems.
• Bio-herbicides: natural allelochemicals can replace part of the synthetic herbicides on which irrigated farming depends.

Harmful role

• Weeds such as Parthenium and Cyperus release chemicals that reduce crop germination and vigour, and agroforestry trees can suppress crops planted beneath them.
• Autotoxicity: continuous paddy and repeated sugarcane ratoons build up self-inhibiting compounds and cause yield decline.
• Residues: incorporating fresh straw of some crops before it decomposes inhibits the following crop, so the timing of residue management matters.

Way forward

• Breed allelopathic cultivars, plan rotations and intercrops, manage residues by mulching or timed incorporation rather than burning, and test effects before promotion.

Used with care, allelopathy can cut chemical use and support sustainable irrigated farming; its harmful side must be managed through rotation and residue handling.

Land reform changes who owns and controls land, and therefore who has the security and incentive to invest in it. After Independence India pursued abolition of intermediaries, tenancy reform, ceilings on holdings and consolidation.

Role in agricultural development

• Security and incentive: ownership or secure tenancy encourages investment in irrigation, seeds and inputs, raising productivity.
• Ending intermediaries: abolition of zamindari brought the tiller into direct relation with the State and ended rent-seeking by absentee landlords.
• Equity and productivity: ceilings and redistribution reduce inequality, and owner-operated small holdings are often more productive per hectare.
• Consolidation and records: fewer fragments and clear titles cut costs and disputes and make credit accessible.

Factors behind success

• Political will with legal protection: the First Amendment (1951) added Articles 31A and 31B and the Ninth Schedule, shielding land reform laws from fundamental-rights challenge, so abolition of intermediaries succeeded nationwide.
• Committed governments and organised peasants: in West Bengal, Operation Barga (from 1978) recorded sharecroppers and secured them against eviction; in Kerala, mobilised tenants and a determined government made tenancy reform effective.
• Administrative machinery: updated land records, village-level officials and panchayat involvement in identifying tenants and surplus land.
• Where these were absent, loopholes, concealed tenancy, benami transfers and landlord influence diluted ceilings and tenancy laws, and land stayed concentrated.

Unfinished agenda

• Digitised land records, legal recognition of tenancy, women's land titles and land pooling or leasing for small farmers.

Land reform raised both equity and productivity wherever political will, constitutional protection and administrative capacity came together; completing that agenda remains part of agricultural development.

Much of India's farming depends on the monsoon, and a single drought, flood or hailstorm can wipe out a season's income and push a family into debt. Crop insurance spreads that risk across farmers, insurers and the State.

Need for crop insurance

• Weather shocks, pests and disease cause sudden income loss; small farmers have thin savings, so loss turns into debt and distress.
• Insurance stabilises incomes, keeps credit flowing because banks lend more readily to insured farmers, and encourages adoption of new inputs and crops.
• It is more predictable and less distorting than ad hoc relief and loan waivers.
• Earlier schemes, NAIS and MNAIS, had high premiums, capped sums insured, low coverage and delayed claims.

Salient features of PMFBY

• Approved in 2016 and implemented from kharif 2016, replacing NAIS and MNAIS.
• Low, uniform premium: farmers pay at most 2 per cent for kharif food and oilseed crops, 1.5 per cent for rabi crops and 5 per cent for commercial and horticultural crops; the Centre and States share the rest without a cap, so the full sum insured is covered.
• Comprehensive cover: prevented sowing, standing crop loss from natural risks, post-harvest losses and localised calamities such as hailstorm, landslide and inundation, the last assessed at the individual farm.
• Technology: smartphones for crop-cutting experiments, remote sensing and drones to speed assessment, with claims paid directly into bank accounts.
• Compulsory for loanee farmers and voluntary for others (since then, voluntary for all farmers from 2020).
• Issues: delayed claims, low awareness, poor yield data and insurers' losses in bad years.

Timely and accurate yield assessment, quick claim payment and farmer awareness will decide whether PMFBY becomes a dependable shield against nature.
